Skyscraper
–
A skyscraper is a tall, continuously habitable building having multiple floors. When the term was used in the 1880s it described a building of 10 to 20 floors. Mostly designed for office, commercial and residential uses, a skyscraper can also be called a high-rise, for buildings above a height of 300 m, the term supertall can be used, while skyscrapers reaching beyond 600 m are classified as megatall. One common feature of skyscrapers is having a steel framework that supports curtain walls and these curtain walls either bear on the framework below or are suspended from the framework above, rather than resting on load-bearing walls of conventional construction. Some early skyscrapers have a frame that enables the construction of load-bearing walls taller than of those made of reinforced concrete. Modern skyscrapers walls are not load-bearing, and most skyscrapers are characterized by surface areas of windows made possible by steel frames. However, skyscrapers can have curtain walls that mimic conventional walls with a surface area of windows. Modern skyscrapers often have a structure, and are designed to act like a hollow cylinder to resist wind, seismic. To appear more slender, allow less wind exposure, and transmit more daylight to the ground, many skyscrapers have a design with setbacks, a relatively big building may be considered a skyscraper if it protrudes well above its built environment and changes the overall skyline. The maximum height of structures has progressed historically with building methods and technologies, the Burj Khalifa is currently the tallest building in the world. High-rise buildings are considered shorter than skyscrapers, the first steel-frame skyscraper was the Home Insurance Building in Chicago, Illinois in 1885. Even the scholars making the argument find it to be purely academic and this definition was based on the steel skeleton—as opposed to constructions of load-bearing masonry, which passed their practical limit in 1891 with Chicagos Monadnock Building. What is the characteristic of the tall office building. The force and power of altitude must be in it, the glory and it must be every inch a proud and soaring thing, rising in sheer exaltation that from bottom to top it is a unit without a single dissenting line. Some structural engineers define a highrise as any vertical construction for which wind is a significant load factor than earthquake or weight. Note that this criterion fits not only high-rises but some other tall structures, the word skyscraper often carries a connotation of pride and achievement. A loose convention of some in the United States and Europe draws the limit of a skyscraper at 150 m or 490 ft. The tallest building in ancient times was the 146 m Great Pyramid of Giza in ancient Egypt and it was not surpassed in height for thousands of years, the 14th century AD Lincoln Cathedral being conjectured by many to have exceeded it

Melbourne
–
Melbourne is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in Australia and Oceania. The name Melbourne refers to an urban agglomeration spanning 9,900 km2, the metropolis is located on the large natural bay of Port Phillip and expands into the hinterlands towards the Dandenong and Macedon mountain ranges, Mornington Peninsula and Yarra Valley. It has a population of 4,641,636 as of 2016, and its inhabitants are called Melburnians. Founded by free settlers from the British Crown colony of Van Diemens Land on 30 August 1835, in what was then the colony of New South Wales, it was incorporated as a Crown settlement in 1837. It was named Melbourne by the Governor of New South Wales, Sir Richard Bourke, in honour of the British Prime Minister of the day, William Lamb, 2nd Viscount Melbourne. It was officially declared a city by Queen Victoria, to whom Lord Melbourne was close, in 1847, during the Victorian gold rush of the 1850s, it was transformed into one of the worlds largest and wealthiest cities. After the federation of Australia in 1901, it served as the interim seat of government until 1927. It is a financial centre in the Asia-Pacific region. It is recognised as a UNESCO City of Literature and a centre for street art, music. It was the host city of the 1956 Summer Olympics and the 2006 Commonwealth Games, the main passenger airport serving the metropolis and the state is Melbourne Airport, the second busiest in Australia. The Port of Melbourne is Australias busiest seaport for containerised and general cargo, Melbourne has an extensive transport network. The main metropolitan train terminus is Flinders Street Station, and the regional train. Melbourne is also home to Australias most extensive network and has the worlds largest urban tram network. Before the arrival of settlers, humans had occupied the area for an estimated 31,000 to 40,000 years. At the time of European settlement, it was inhabited by under 2000 hunter-gatherers from three indigenous tribes, the Wurundjeri, Boonwurrung and Wathaurong. The area was an important meeting place for the clans of the Kulin nation alliance and it would be 30 years before another settlement was attempted. Batman selected a site on the bank of the Yarra River. Batman then returned to Launceston in Tasmania, in early August 1835 a different group of settlers, including John Pascoe Fawkner, left Launceston on the ship Enterprize

Australia
–
Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the worlds sixth-largest country by total area, the neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north, the Solomon Islands and Vanuatu to the north-east, and New Zealand to the south-east. Australias capital is Canberra, and its largest urban area is Sydney, for about 50,000 years before the first British settlement in the late 18th century, Australia was inhabited by indigenous Australians, who spoke languages classifiable into roughly 250 groups. The population grew steadily in subsequent decades, and by the 1850s most of the continent had been explored, on 1 January 1901, the six colonies federated, forming the Commonwealth of Australia. Australia has since maintained a liberal democratic political system that functions as a federal parliamentary constitutional monarchy comprising six states. The population of 24 million is highly urbanised and heavily concentrated on the eastern seaboard, Australia has the worlds 13th-largest economy and ninth-highest per capita income. With the second-highest human development index globally, the country highly in quality of life, health, education, economic freedom. The name Australia is derived from the Latin Terra Australis a name used for putative lands in the southern hemisphere since ancient times, the Dutch adjectival form Australische was used in a Dutch book in Batavia in 1638, to refer to the newly discovered lands to the south. On 12 December 1817, Macquarie recommended to the Colonial Office that it be formally adopted, in 1824, the Admiralty agreed that the continent should be known officially as Australia. The first official published use of the term Australia came with the 1830 publication of The Australia Directory and these first inhabitants may have been ancestors of modern Indigenous Australians. The Torres Strait Islanders, ethnically Melanesian, were originally horticulturists, the northern coasts and waters of Australia were visited sporadically by fishermen from Maritime Southeast Asia. The first recorded European sighting of the Australian mainland, and the first recorded European landfall on the Australian continent, are attributed to the Dutch. The first ship and crew to chart the Australian coast and meet with Aboriginal people was the Duyfken captained by Dutch navigator, Willem Janszoon. He sighted the coast of Cape York Peninsula in early 1606, the Dutch charted the whole of the western and northern coastlines and named the island continent New Holland during the 17th century, but made no attempt at settlement. William Dampier, an English explorer and privateer, landed on the north-west coast of New Holland in 1688, in 1770, James Cook sailed along and mapped the east coast, which he named New South Wales and claimed for Great Britain. The first settlement led to the foundation of Sydney, and the exploration, a British settlement was established in Van Diemens Land, now known as Tasmania, in 1803, and it became a separate colony in 1825. The United Kingdom formally claimed the part of Western Australia in 1828. Separate colonies were carved from parts of New South Wales, South Australia in 1836, Victoria in 1851, the Northern Territory was founded in 1911 when it was excised from South Australia

Crane (machine)
–
A crane is a type of machine, generally equipped with a hoist rope, wire ropes or chains, and sheaves, that can be used both to lift and lower materials and to move them horizontally. It is mainly used for lifting heavy things and transporting them to other places, the device uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. The first known construction cranes were invented by the Ancient Greeks and were powered by men or beasts of burden and these cranes were used for the construction of tall buildings. Larger cranes were later developed, employing the use of human treadwheels, in the High Middle Ages, harbour cranes were introduced to load and unload ships and assist with their construction – some were built into stone towers for extra strength and stability. The earliest cranes were constructed from wood, but cast iron, iron, for many centuries, power was supplied by the physical exertion of men or animals, although hoists in watermills and windmills could be driven by the harnessed natural power. The first mechanical power was provided by steam engines, the earliest steam crane being introduced in the 18th or 19th century, Cranes exist in an enormous variety of forms – each tailored to a specific use. Sizes range from the smallest jib cranes, used inside workshops, to the tallest tower cranes, mini-cranes are also used for constructing high buildings, in order to facilitate constructions by reaching tight spaces. Finally, we can find larger floating cranes, generally used to oil rigs. Some lifting machines do not strictly fit the definition of a crane. The crane for lifting heavy loads was invented by the Ancient Greeks in the late 6th century BC, the archaeological record shows that no later than c.515 BC distinctive cuttings for both lifting tongs and lewis irons begin to appear on stone blocks of Greek temples. The introduction of the winch and pulley hoist soon lead to a replacement of ramps as the main means of vertical motion. Also, the practice of erecting large monolithic columns was abandoned in favour of using several column drums. The first unequivocal evidence for the existence of the compound pulley system appears in the Mechanical Problems attributed to Aristotle. The heyday of the crane in ancient times came during the Roman Empire, the Romans adopted the Greek crane and developed it further. We are relatively well informed about their techniques, thanks to rather lengthy accounts by the engineers Vitruvius. There are also two surviving reliefs of Roman treadwheel cranes, with the Haterii tombstone from the late first century AD being particularly detailed, the simplest Roman crane, the trispastos, consisted of a single-beam jib, a winch, a rope, and a block containing three pulleys. Heavier crane types featured five pulleys or, in case of the largest one, the polyspastos, when worked by four men at both sides of the winch, could readily lift 3,000 kg. At the temple of Jupiter at Baalbek, for instance, the blocks weigh up to 60 tons each

Cologne
–
Cologne is the largest city in the German federal State of North Rhine-Westphalia and the fourth-largest city in Germany. It is located within the Rhine-Ruhr metropolitan region, one of the major European metropolitan areas, and with more than ten million inhabitants, Cologne is located on both sides of the Rhine River, less than eighty kilometres from Belgium. The citys famous Cologne Cathedral is the seat of the Catholic Archbishop of Cologne, the University of Cologne is one of Europes oldest and largest universities. Cologne was founded and established in Ubii territory in the first century AD as the Roman Colonia Claudia Ara Agrippinensium, Cologne, the French version of the citys name, has become standard in English as well. The city functioned as the capital of the Roman province of Germania Inferior, during the Middle Ages it flourished on one of the most important major trade routes between east and west in Europe. Cologne was one of the members of the Hanseatic League and one of the largest cities north of the Alps in medieval. Up until World War II the city had several occupations by the French. Cologne was one of the most heavily bombed cities in Germany during World War II, the bombing reduced the population by 95%, mainly due to evacuation, and destroyed almost the entire city. With the intention of restoring as many buildings as possible. Cologne is a cultural centre for the Rhineland, it hosts more than thirty museums. Exhibitions range from local ancient Roman archeological sites to contemporary graphics, the Cologne Trade Fair hosts a number of trade shows such as Art Cologne, imm Cologne, Gamescom, and the Photokina. The first urban settlement on the grounds of modern-day Cologne was Oppidum Ubiorum, founded in 38 BC by the Ubii, in 50 AD, the Romans founded Colonia on the Rhine and the city became the provincial capital of Germania Inferior in 85 AD. The city was named Colonia Claudia Ara Agrippinensium in 50 AD, considerable Roman remains can be found in present-day Cologne, especially near the wharf area, where a notable discovery of a 1900-year-old Roman boat was made in late 2007. From 260 to 271 Cologne was the capital of the Gallic Empire under Postumus, Marius, in 310 under Constantine a bridge was built over the Rhine at Cologne. Roman imperial governors resided in the city and it one of the most important trade. Cologne is shown on the 4th century Peutinger Map, maternus, who was elected as bishop in 313, was the first known bishop of Cologne. The city was the capital of a Roman province until occupied by the Ripuarian Franks in 462, parts of the original Roman sewers are preserved underneath the city, with the new sewerage system having opened in 1890. Early medieval Cologne was part of Austrasia within the Frankish Empire, Cologne had been the seat of a bishop since the Roman period, under Charlemagne, in 795, bishop Hildebold was promoted to archbishop

Building
–
A building or edifice is a structure with a roof and walls standing more or less permanently in one place, such as a house or factory. To better understand the term building compare the list of nonbuilding structures, Buildings serve several needs of society – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a division of the human habitat. Ever since the first cave paintings, buildings have become objects or canvasses of much artistic expression. In recent years, interest in planning and building practices has also become an intentional part of the design process of many new buildings. The word building is both a noun and a verb also an adverb, the structure itself and the act of making it. As a noun, a building is a structure that has a roof and walls and stands more or less permanently in one place, there was a building on the corner. In the broadest interpretation a fence or wall is a building, however, the word structure is used more broadly than building including natural and man-made formations and does not necessarily have walls. Structure is more likely to be used for a fence, as a verb, building is the act of construction. Structural height in technical usage is the height to the highest architectural detail on building from street-level, depending on how they are classified, spires and masts may or may not be included in this height. Spires and masts used as antennas are not generally included, the definition of a low-rise vs. a high-rise building is a matter of debate, but generally three storeys or less is considered low-rise. A report by Shinichi Fujimura of a shelter built 500000 years ago is doubtful since Fujimura was later found to have faked many of his findings. Supposed remains of huts found at the Terra Amata site in Nice purportedly dating from 200000 to 400000 years ago have also called into question. There is clear evidence of homebuilding from around 18000 BC, Buildings became common during the Neolithic. Single-family residential buildings are most often called houses or homes, residential buildings containing more than one dwelling unit are called a duplex, apartment building to differentiate them from individual houses. A condominium is an apartment that the occupant owns rather than rents, houses which were built as a single dwelling may later be divided into apartments or bedsitters, they may also be converted to another use e. g. an office or a shop. Building types may range from huts to multimillion-dollar high-rise apartment blocks able to house thousands of people, increasing settlement density in buildings is usually a response to high ground prices resulting from many people wanting to live close to work or similar attractors. Other common building materials are brick, concrete or combinations of either of these with stone, also if the residents are in need of special care such as a nursing home, orphanage or prison, or in group housing like barracks or dormitories

Infrastructure
–
Infrastructure refers to the fundamental facilities and systems serving a country, city, or area, including the services and facilities necessary for its economy to function. The word was imported from French, where it means subgrade, the word is a combination of the Latin prefix infra, meaning below, and structure. The military use of the term achieved currency in the United States after the formation of NATO in the 1940s and this crisis discussion contributed to an increase in infrastructure asset management and maintenance planning in the US. Public-policy discussions have been hampered by lack of a definition for infrastructure. A1987 US National Research Council panel adopted the public works infrastructure. The OECD also classifies communications as a part of infrastructure, the American Society of Civil Engineers has not defined the term, though issuing a US Infrastructure Report Card every 2-4 years. Hard infrastructure refers to the physical networks necessary for the functioning of an industrial nation. The term critical infrastructure distinguishes those infrastructure elements that, if damaged or destroyed. Similarly, a booking system might be critical infrastructure for an airline. These elements of infrastructure are the focus of efforts in the aftermath of natural disasters. The term infrastructure may be confused with the following overlapping or related concepts, service connections to municipal service and public utility networks would also be considered land improvements, not infrastructure. The term public works includes government-owned and operated infrastructure as well as buildings, such as schools. Public works generally refers to physical assets needed to deliver public services, public services include both infrastructure and services generally provided by government. Infrastructure may be owned and managed by governments or by private companies, generally, most roads, major ports and airports, water distribution systems and sewage networks are publicly owned, whereas most energy and telecommunications networks are privately owned. Publicly owned infrastructure may be paid for taxes, tolls, or metered user fees. Major investment projects are financed by the issuance of long-term bonds. Government owned and operated infrastructure may be developed and operated in the sector or in public-private partnerships. As of 2008 in the United States for example, public spending on infrastructure has varied between 2. 3% and 3. 6% of GDP since 1950, many financial institutions invest in infrastructure

Manufacturing
–
Manufacturing is the value added to production of merchandise for use or sale using labour and machines, tools, chemical and biological processing, or formulation. Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product, the manufacturing process begins with the product design, and materials specification from which the product is made. These materials are modified through manufacturing processes to become the required part. Manufacturing takes turns under all types of economic systems, in a free market economy, manufacturing is usually directed toward the mass production of products for sale to consumers at a profit. In a collectivist economy, manufacturing is more directed by the state to supply a centrally planned economy. In mixed market economies, manufacturing occurs under some degree of government regulation, modern manufacturing includes all intermediate processes required the production and integration of a products components. Some industries, such as semiconductor and steel manufacturers use the term fabrication instead, the manufacturing sector is closely connected with engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Electric, Procter & Gamble, General Dynamics, Boeing, Pfizer, examples in Europe include Volkswagen Group, Siemens, and Michelin. Examples in Asia include Sony, Huawei, Lenovo, Toyota, Samsung, in its earliest form, manufacturing was usually carried out by a single skilled artisan with assistants. In much of the world, the guild system protected the privileges. Before the Industrial Revolution, most manufacturing occurred in rural areas, entrepreneurs organized a number of manufacturing households into a single enterprise through the putting-out system. Toll manufacturing is an arrangement whereby a first firm with specialized equipment processes raw materials or semi-finished goods for a second firm, manufacturing provides important material support for national infrastructure and for national defense. On the other hand, most manufacturing may involve significant social and environmental costs, the clean-up costs of hazardous waste, for example, may outweigh the benefits of a product that creates it. Hazardous materials may expose workers to health risks and these costs are now well known and there is effort to address them by improving efficiency, reducing waste, using industrial symbiosis, and eliminating harmful chemicals. The negative costs of manufacturing can also be addressed legally, developed countries regulate manufacturing activity with labor laws and environmental laws. Across the globe, manufacturers can be subject to regulations and pollution taxes to offset the costs of manufacturing activities. Labor unions and craft guilds have played a role in the negotiation of worker rights. Environment laws and labor protections that are available in developed nations may not be available in the third world, tort law and product liability impose additional costs on manufacturing

Mass production
–
Mass production, flow production or continuous production is the production of large amounts of standardized products, including and especially on assembly lines. Together with job production and batch production, it is one of the three main production methods, the term mass production was popularized by a 1926 article in the Encyclopedia Britannica supplement that was written based on correspondence with Ford Motor Company. The New York Times used the term in the title of an article that appeared before publication of the Britannica article, the concepts of mass production are applied to various kinds of products, from fluids and particulates handled in bulk to discrete solid parts to assemblies of such parts. Mass production is a field, but it can generally be contrasted with craft production or distributed manufacturing. Mass production of fluid matter typically involves pipes with centrifugal pumps or screw conveyors to transfer raw materials or partially complete products between vessels, materials on pallets are handled with forklifts. Also used for handling heavy items like reels of paper, steel or machinery are electric overhead cranes, sometimes called bridge cranes because they span large factory bays. Mass production is intensive and energy intensive, as it uses a high proportion of machinery. It is also usually automated while total expenditure per unit of product is decreased, however, the machinery that is needed to set up a mass production line is so expensive that there must be some assurance that the product is to be successful to attain profits. One of the descriptions of mass production is that the skill is built into the tool, for example, in the 19th or early 20th century, this could be expressed as the craftsmanship is in the workbench itself. Later, once computerized control came about, jigs were obviated and this is the specialized capital required for mass production, each workbench and set of tools is different. Crossbows made with bronze parts were produced in China during the Warring States period, the Qin Emperor unified China at least in part by equipping large armies with these weapons, which were equipped with a sophisticated trigger mechanism made of interchangeable parts. Ships of war were produced on a scale at a moderate cost by the Carthaginians in their excellent harbors. The Venetians themselves also produced ships using prefabricated parts and assembly lines many centuries later, the Venetian Arsenal apparently produced nearly one ship every day, in what was effectively the worlds first factory which, at its height, employed 16,000 people. Mass production in the industry has been commonplace since the Gutenberg Bible was published using a printing press in the mid-15th century. In the Industrial Revolution simple mass production techniques were used at the Portsmouth Block Mills in England to make ships pulley blocks for the Royal Navy in the Napoleonic Wars. It was achieved in 1803 by Marc Isambard Brunel in cooperation with Henry Maudslay under the management of Sir Samuel Bentham, the Navy was in a state of expansion that required 100,000 pulley blocks to be manufactured a year. Bentham had already achieved remarkable efficiency at the docks by introducing power-driven machinery, by 1805, the dockyard had been fully updated with the revolutionary, purpose-built machinery at a time when products were still built individually with different components. A total of 45 machines were required to perform 22 processes on the blocks, the machines were almost entirely made of metal thus improving their accuracy and durability

Industry
–
Industry is the production of goods or related services within an economy. The major source of revenue of a group or company is the indicator of its relevant industry, when a large group has multiple sources of revenue generation, it is considered to be working in different industries. Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and this came through many successive rapid advances in technology, such as the production of steel and coal. Following the Industrial Revolution, possibly a third of the economic output are derived that is from manufacturing industries. Many developed countries and many developing/semi-developed countries depend significantly on manufacturing industry, Industries, the countries they reside in, and the economies of those countries are interlinked in a complex web of interdependence. Industries can be classified in a variety of ways, at the top level, industry is often classified according to the three-sector theory into sectors, primary, secondary, and tertiary. Some authors add quaternary or even quinary sectors, over time, the fraction of a societys industry within each sector changes. Below the economic sectors there are other more detailed industry classifications. These classification systems commonly divide industries according to functions and markets. Market-based classification systems such as the Global Industry Classification Standard and the Industry Classification Benchmark are used in finance, the International Standard Industrial Classification of all economic activities is the most complete and systematic industrial classification made by the United Nations Statistics Division. ISIC is a classification of economic activities arranged so that entities can be classified according to the activity they carry out. The Industrial Revolution led to the development of factories for large-scale production, originally the factories were steam-powered, but later transitioned to electricity once an electrical grid was developed. The mechanized assembly line was introduced to parts in a repeatable fashion. This led to significant increases in efficiency, lowering the cost of the end process, later automation was increasingly used to replace human operators. This process has accelerated with the development of the computer and the robot, historically certain manufacturing industries have gone into a decline due to various economic factors, including the development of replacement technology or the loss of competitive advantage. An example of the former is the decline in manufacturing when the automobile was mass-produced. A recent trend has been the migration of prosperous, industrialized nations towards a post-industrial society and this is manifested by an increase in the service sector at the expense of manufacturing, and the development of an information-based economy, the so-called informational revolution. In a post-industrial society, manufacturing is relocated to more favourable locations through a process of off-shoring

Gross domestic product
–
Gross Domestic Product is a monetary measure of the market value of all final goods and services produced in a period. Nominal GDP estimates are used to determine the economic performance of a whole country or region. The OECD defines GDP as a measure of production equal to the sum of the gross values added of all resident and institutional units engaged in production. ”An IMF publication states that GDP measures the monetary value of final goods and services - that is. Total GDP can also be broken down into the contribution of industry or sector of the economy. The ratio of GDP to the population of the region is the per capita GDP. William Petty came up with a concept of GDP to defend landlords against unfair taxation during warfare between the Dutch and the English between 1652 and 1674. Charles Davenant developed the method further in 1695, the modern concept of GDP was first developed by Simon Kuznets for a US Congress report in 1934. In this report, Kuznets warned against its use as a measure of welfare, after the Bretton Woods conference in 1944, GDP became the main tool for measuring a countrys economy. The switch from GNP to GDP in the US was in 1991, the history of the concept of GDP should be distinguished from the history of changes in ways of estimating it. The value added by firms is relatively easy to calculate from their accounts, but the value added by the sector, by financial industries. GDP can be determined in three ways, all of which should, in principle, give the same result and they are the production approach, the income approach, or the expenditure approach. The most direct of the three is the approach, which sums the outputs of every class of enterprise to arrive at the total. The income approach works on the principle that the incomes of the factors must be equal to the value of their product. This approach mirrors the OECD definition given above, deduct intermediate consumption from gross value to obtain the gross value added. Gross value added = gross value of output – value of intermediate consumption, value of output = value of the total sales of goods and services plus value of changes in the inventories. The sum of the value added in the various economic activities is known as GDP at factor cost. GDP at factor cost plus indirect taxes less subsidies on products = GDP at producer price, for measuring output of domestic product, economic activities are classified into various sectors. Subtracting each sectors intermediate consumption from gross output gives the GDP at factor cost, adding indirect tax minus subsidies in GDP at factor cost gives the GDP at producer prices

Developed country
–
Which criteria are to be used and which countries can be classified as being developed are subjects of debate. Developed countries have post-industrial economies, meaning the sector provides more wealth than the industrial sector. They are contrasted with developing countries, which are in the process of industrialization, or undeveloped countries, which are pre-industrial and almost entirely agrarian. As of 2015, advanced economies comprise 60. 8% of global GDP based on values and 42. 9% of global GDP based on purchasing-power parity according to the International Monetary Fund. In 2015, the ten largest advanced economies by GDP in both nominal and PPP terms were Australia, Canada, France, Germany, Italy, Japan, South Korea, Spain, the United Kingdom, and the United States. The term industrialized country may be ambiguous, as industrialization is an ongoing process that is hard to define. The first industrialized country was the United Kingdom, followed by Belgium, later it spread further to Germany, United States, France and other Western European countries. According to some such as Jeffrey Sachs, however, the current divide between the developed and developing world is largely a phenomenon of the 20th century. Economic criteria have tended to dominate discussions, one such criterion is income per capita, countries with high gross domestic product per capita would thus be described as developed countries. Another economic criterion is industrialization, countries in which the tertiary and quaternary sectors of industry dominate would thus be described as developed. More recently another measure, the Human Development Index, which combines an economic measure, national income, with other measures, indices for life expectancy and this criterion would define developed countries as those with a very high rating. According to the United Nations Statistics Division, There is no established convention for the designation of developed, the UN HDI is a statistical measure that gauges a countrys level of human development. While there is a correlation between having a high HDI score and a prosperous economy, the UN points out that the HDI accounts for more than income or productivity. Unlike GDP per capita or per capita income, the HDI takes into account how income is turned into education and health opportunities, since 1990, Norway, Japan, Canada and Iceland have had the highest HDI score. The top 47 countries have scores ranging from 0.793 in Barbados to 0.955 in Norway, many countries listed by IMF or CIA as advanced, possess an HDI over 0.788. Many countries possessing an HDI of 0.788 and over are also listed by IMF or CIA as advanced, thus, many advanced economies are characterized by an HDI score of 0.9 or higher. Since April 2016, the IMF classifies Macau as an advanced economy, the latest index was released on 14 December 2015 and covers the period up to 2014. The following are the 49 countries in the top quartile - having an HDI above 0.8, = Increase = No increase or decrease = Decrease The number in parentheses represents the number of ranks the country has climbed relative to the ranking in 2014 report

Collaboration
–
Collaboration is the process of two or more people or organizations working together to realize or achieve something successfully. Collaboration is very similar to, but more closely aligned than, Most collaboration requires leadership, although the form of leadership can be social within a decentralized and egalitarian group. Teams that work collaboratively can obtain resources, recognition and reward when facing competition for finite resources. Structured methods of collaboration encourage introspection of behavior and communication and these methods specifically aim to increase the success of teams as they engage in collaborative problem solving. Forms, rubrics, charts and graphs are useful in situations to objectively document personal traits with the goal of improving performance in current. Collaboration is also present in opposing goals exhibiting the notion of adversarial collaboration, following are some examples of successful collaboration efforts in the past. Trade originated with the start of communication in prehistoric times, trading was the main facility of prehistoric people, who bartered goods and services from each other when there was no such thing as the modern day currency. Peter Watson dates the history of commerce from circa 150,000 years ago. Due to specialisation and division of labor, most people concentrate on an aspect of production. As such, trade at prices between locations benefits both locations. The members of an intentional community typically hold a social, political or spiritual vision. They also share responsibilities and resources, intentional communities include cohousing, residential land trusts, ecovillages, communes, kibbutzim, ashrams, and housing cooperatives. Typically, new members of a community are selected by the communitys existing membership. Hutterite, Austria Housing units are built and assigned to families but belong to the colony. Meals are taken by the colony in a common long room. The goal was to eliminate bad character traits, early Kibbutz settlements founded near Jerusalem A Kibbutz is an Israeli collective community. The movement combines socialism and Zionism in a form of practical Labor Zionism, forced by necessity into communal life, and inspired by their own ideology, the kibbutz members developed a pure communal mode of living that attracted interest from the entire world. Ayn Rand utterly rejected the notion that one should live an isolated life, Rand wrote hundreds of pages about the virtues and benefits of collaborating with others to mutual advantage

Project manager
–
A project manager is a professional in the field of project management. Project managers have the responsibility of the planning, procurement and execution of a project, Project managers are first point of contact for any issues or discrepancies arising from within the heads of various departments in an organization before the problem escalates to higher authorities. Project management is the responsibility of a project manager, a project manager is the person responsible for accomplishing the project objectives. An expertise is required in the domain the Project Managers are working to efficiently handle all the aspects of the project, Project Tools The tools, knowledge and techniques for managing projects are often unique to Project Management. For example, work breakdown structures, critical analysis and earned value management. Understanding and applying the tools and techniques which are recognized as good practices are not sufficient alone for effective project management. Effective project management requires that the project manager understands and uses the knowledge, Project Teams When recruiting and building an effective team, the manager must consider not only the technical skills of each person, but also the critical roles and chemistry between workers. A project team has three separate components, Project Manager, Core Team and Contracted Team. Risk Most of the project management issues that influence a project arise from risk, until recently, the American construction industry lacked any level of standardization, with individual States determining the eligibility requirements within their jurisdiction. However, several Trade associations based in the United States have made strides in creating a commonly accepted set of qualifications, the Construction Management Association of America maintains the Certified Construction Manager designation. The purpose of the CCM is to standardize the education, experience, the Project Management Institute has made some headway into being a standardizing body with its creation of the Project Management Professional designation. The Constructor Certification Commission of the American Institute of Constructors holds semiannual nationwide tests, the Associated Colleges of Construction Education, and the Associated Schools of Construction have made considerable progress in developing national standards for construction education programs. The profession has grown to accommodate several dozen Construction Management Bachelor of Science programs. Many universities have begun offering a masters degree in Project Management. The United States Navy construction battalions, nicknamed the SeaBees, puts their command through strenuous training, to become a Chief Petty Officer in the SeaBees is equivalent to a BS in Construction Management with the added benefit of several years of experience to their credit. Architectural project manager are project managers in the field of architecture and they have many of the same skills as their counterpart in the construction industry. The issues of budget, scheduling, and quality-control are the responsibility of the Project Manager in an architects office, in the insurance industry project managers often oversee and manage the restoration of a clients home/office after a fire, flood. Covering the fields from electronics through to the demolition and constructions contractors, in Engineering project management is the term used to describe the task of seeing a product/device through the stages of R&D/design to manufacturing stages

Construction management
–
The purpose of CM is to control a projects time, cost and quality. CM is compatible with all project delivery systems, including design-bid-build, design-build, CM At-Risk, every construction project features some amount of CM. However, professional construction managers, or CMs, are reserved for lengthy, large-scale, high budget undertakings. No matter the setting, a CMs responsibility is to the owner, a contractor is assigned to a construction project during the design or once the design has been completed by a licensed architect. This is done by going through a process with different contractors. The contractor is selected by using one of three selection methods, low-bid selection, best-value selection, or qualifications-based selection. A construction manager should have the ability to handle public safety, time management, cost management, quality management, decision making, mathematics, working drawings, maximizing the resource efficiency through procurement of labor, materials and equipment. Implementing various operations through proper coordination and control of planning, design, estimating, contracting, developing effective communications and mechanisms for resolving conflicts. Agricultural, Typically economical buildings, and other improvements, for agricultural purposes, examples include barns, equipment and animal sheds, specialized fencing, storage silos and elevators, and water supply and drains such as wells, tanks, and ditches. Residential, Residential construction includes houses, apartments, townhouses, and other smaller, low-rise housing, commercial, This refers to construction for the needs of private commerce, trade, and services. Institutional, This category is for the needs of government and other public organizations, examples include schools, fire and police stations, libraries, museums, dormitories, research buildings, hospitals, transportation terminals, some military facilities, and governmental buildings. Heavy civil, The construction of infrastructure such as roads, bridges, railroads, tunnels, airports. Dams are also included, but most other water-related infrastructure is considered environmental, Environmental, Environmental construction was part of heavy civil, but is now separate, dealing with projects that improve the environment. Some examples are water and wastewater treatment plants, sanitary and storm sewers, solid waste management, a bid tells the owner how much money they should expect to pay the construction management company in order for them to complete the project. Open bid, An open bid is used for public projects, any and all contractors are allowed to submit their bid due to public advertising. Closed bid, A closed bid is used for private projects, a selection of contractors are sent an invitation for bid so only they can submit a bid for the specified project. Low-bid selection, This selection focuses on the price of a project, Multiple construction management companies submit a bid to the owner that is the lowest amount they are willing to do the job for. Then the owner chooses the company with the lowest bid to complete the job for them

Construction engineer
–
Construction engineering is considered a professional sub-practice area of Civil engineering. Construction technology is a field that deals more with the practical aspects of projects. Construction technologists or construction technicians learn some of the design similar to civil engineers. These technicians are unique such that they are a cross between civil engineers and construction managers, at the educational level, civil engineering students concentrate primarily on the design work, which is more analytical, gearing them toward a career as a design professional. This essentially requires them to take a multitude of challenging engineering science, also, education for construction managers is primarily focused on construction procedures, methods, costs, schedules, and personnel management. Their primary concern is to deliver a project on time, within budget, the difference between a construction technologist and a civil engineer is that civil engineering is an engineering discipline. Construction technology students take basic courses as well as construction management courses. This allows them to understand both basic design functions as well as the requirements needed to design and build todays infrastructures. It should be noted that a career in design work does require a professional engineer license, individuals who pursue this career path are strongly advised to sit for the Engineer In Training exam while in college as it takes five years post graduate to obtain the PE license. Entry-level construction manager positions are typically called project engineers or assistant project engineers and they are responsible for preparing purchasing requisitions, processing change orders, preparing monthly budgeting reports, and handling meeting minutes. They contribute to the creation of infrastructure that best meets the demands of its environment. They must be able to understand infrastructure life cycles, when compared and contrasted to design engineers, construction engineers bring to the table their own unique perspectives for solving technical challenges with clarity and imagination. ABET accreditation is assurance that a college or university program meets the quality standards established by the profession for which it prepares its students, in the US there are currently twenty-five programs that exist in the entire country so careful college consideration is advised. A typical construction engineering curriculum is a mixture of engineering mechanics, engineering design, construction management and general science and this usually leads to a Bachelor of Science degree. The B. S. degree along with some design or construction experience is sufficient for most entry level positions, graduate schools may be an option for those who want to go further in depth of the construction and engineering subjects taught at the undergraduate level. In most cases construction engineering graduates look to either civil engineering, engineering management, job prospects for construction engineers generally have a strong cyclical variation. For example, starting in 2008 - continuing until at least 2011 - job prospects have been due to the collapse of housing bubbles in many parts of the world. In early 2010 the United States construction industry had a 27% unemployment rate, the construction unemployment rate is comparable to the United States 1933 unemployment rate - the lowest point of the Great Depression - of 25%

Architect
–
An architect is someone who plans, designs, and reviews the construction of buildings. Etymologically, architect derives from the Latin architectus, which derives from the Greek, practical, technical, and academic requirements for becoming an architect vary by jurisdiction. The terms architect and architecture are used in the disciplines of landscape architecture, naval architecture. In most jurisdictions, the professional and commercial uses of the terms architect, throughout ancient and medieval history, most architectural design and construction was carried out by artisans—such as stone masons and carpenters, rising to the role of master builder. Until modern times, there was no distinction between architect and engineer. In Europe, the architect and engineer were primarily geographical variations that referred to the same person. It is suggested that various developments in technology and mathematics allowed the development of the gentleman architect. Paper was not used in Europe for drawing until the 15th century, pencils were used more often for drawing by 1600. The availability of both allowed pre-construction drawings to be made by professionals, until the 18th-century, buildings continued to be designed and set out by craftsmen with the exception of high-status projects. In most developed countries, only qualified people with appropriate license, certification, or registration with a relevant body, such licensure usually requires an accredited university degree, successful completion of exams, and a training period. To practice architecture implies the ability to independently of supervision. In many places, independent, non-licensed individuals may perform design services outside the professional restrictions, such design houses, in the architectural profession, technical and environmental knowledge, design and construction management, and an understanding of business are as important as design. However, design is the force throughout the project and beyond. An architect accepts a commission from a client, the commission might involve preparing feasibility reports, building audits, the design of a building or of several buildings, structures, and the spaces among them. The architect participates in developing the requirements the client wants in the building, throughout the project, the architect co-ordinates a design team. Structural, mechanical, and electrical engineers and other specialists, are hired by the client or the architect, the architect hired by a client is responsible for creating a design concept that meets the requirements of that client and provides a facility suitable to the required use. In that, the architect must meet with and question the client to ascertain all the requirements, often the full brief is not entirely clear at the beginning, entailing a degree of risk in the design undertaking. The architect may make proposals to the client which may rework the terms of the brief

Environmental impact assessment
–
Environmental assessment is the assessment of the environmental consequences of a plan, policy, program, or concrete projects prior to the decision to move forward with the proposed action. Environmental assessments may be governed by rules of administrative procedure regarding public participation and documentation of decision making, the purpose of the assessment is to ensure that decision makers consider the environmental impacts when deciding whether or not to proceed with a project. Environmental impact assessments commenced in the 1960s, as part of increasing environmental awareness, EIAs involved a technical evaluation intended to contribute to more objective decision making. In the United States, environmental impact assessments obtained formal status in 1969, EIAs have been used increasingly around the world. The number of Environmental Assessments filed every year has vastly overtaken the number of more rigorous Environmental Impact Statements, an Environmental Assessment is a mini-EIS designed to provide sufficient information to allow the agency to decide whether the preparation of a full-blown Environmental Impact Statement is necessary. EIA is an activity that is done to find out the impact that would be done before development will occur and these EIAs consider activities related to extraction of raw materials, ancillary materials, equipment, production, use, disposal and ancillary equipment. Genetically modified plants - Specific methods available to perform EIAs of genetically modified organisms include GMP-RAM, fuzzy logic - EIA methods need measurement data to estimate values of impact indicators. However, many of the environment impacts cannot be quantified, e. g. landscape quality, lifestyle quality, instead information from similar EIAs, expert judgment and community sentiment are employed. Approximate reasoning methods known as fuzzy logic can be used, a fuzzy arithmetic approach has also been proposed and implemented using a software tool. At the end of the project, an audit evaluates the accuracy of the EIA by comparing actual to predicted impacts, the objective is to make future EIAs more valid and effective. The Hydropower Sustainability Assessment Protocol is a specific method for checking the quality of Environmental and Social assessments. The history of EIA in Australia could be linked to the enactment of the U. S. National Environment Policy Act in 1970, which made the preparation of environmental impact statements a requirement. In Australia, one might say that the EIA procedures were introduced at a State Level prior to that of the Commonwealth, with a majority of the states having divergent views to the Commonwealth. One of the states was New South Wales, whose State Pollution Control Commission issued EIA guidelines in 1974. At a Commonwealth level, this was followed by passing of the Environment Protection Act in 1974, the Environment Protection and Biodiversity Conservation Act 1999 superseded the Environment Protection Act 1974 and is the current central piece for EIA in Australia on a Commonwealth level. Overlap between federal and state requirements is addressed via bilateral agreements or one off accreditation of state processes, in addition to this, the EPBC Act aims at providing a streamlined national assessment and approval process for activities. The Department of Environment, Water, Heritage and the Arts assess the process and this is primarily due to the division of powers between the States and the Federal government and due to which the Australian Government environment minister cannot overturn a state decision. There are strict civil and criminal penalties for the breach of EPBC Act, EIA provisions within Ministerial Authorities in the ACT are found in the Chapters 7 and 8 of the Planning and Development Act 2007

Scheduling (production processes)
–
Scheduling is the process of arranging, controlling and optimizing work and workloads in a production process or manufacturing process. Scheduling is used to plant and machinery resources, plan human resources, plan production processes. It is an important tool for manufacturing and engineering, where it can have a impact on the productivity of a process. In manufacturing, the purpose of scheduling is to minimize the time and costs, by telling a production facility when to make, with which staff. Production scheduling aims to maximize the efficiency of the operation and reduce costs, Scheduling is the process of arranging, controlling and optimizing work and workloads in a production process. Companies use backward and forward scheduling to allocate plant and machinery resources, plan human resources, plan production processes, forward scheduling is planning the tasks from the date resources become available to determine the shipping date or the due date. Backward scheduling is planning the tasks from the due date or required-by date to determine the start date and/or any changes in capacity required, a key character of scheduling is the productivity, the relation between quantity of inputs and quantity of output. Key concepts here are, Inputs, Inputs are plant, labor, materials, tooling, energy, Outputs, Outputs are the products produced in factories either for other factories or for the end buyer. The extent to which any one product is produced within any one factory is governed by transaction cost, output within the factory, The output of any one work area within the factory is an input to the next work area in that factory according to the manufacturing process. For example, the output of cutting is an input to the bending room, output for the next factory, By way of example, the output of a paper mill is an input to a print factory. The output of a plant is an input to an asphalt plant, a cosmetics factory. Output for the end buyer, Factory output goes to the consumer via a business such as a retailer or an asphalt paving company. Resource allocation, Resource allocation is assigning inputs to produce output, the aim is to maximize output with given inputs or to minimize quantity of inputs to produce required output. Production scheduling can take a significant amount of computing power if there are a number of tasks. Batch production scheduling shares some concepts and techniques with finite capacity scheduling which has applied to many manufacturing problems. The specific issues of scheduling batch manufacturing processes have generated considerable industrial, a batch process can be described in terms of a recipe which comprises a bill of materials and operating instructions which describe how to make the product. The ISA S88 batch process control standard provides a framework for describing a batch process recipe, the standard provides a procedural hierarchy for a recipe. A recipe may be organized into a series of unit-procedures or major steps, unit-procedures are organized into operations, and operations may be further organized into phases

Budget
–
A budget is a quantitative expression of a financial plan for a defined period of time. It may include planned sales volumes and revenues, resource quantities, costs and expenses, assets, liabilities and it expresses strategic plans of business units, organizations, activities or events in measurable terms. A budget is the sum of money allocated for a particular purpose, a budget is a quantified financial plan for a forthcoming accounting period. A budget is an important concept in microeconomics, which uses a line to illustrate the trade-offs between two or more goods. In other terms, a budget is an organizational plan stated in monetary terms and it also helps to co-ordinate the activities of the organization by compelling managers to examine relationships between their own operation and those of other departments. Other essentials of budget include, To control resources To communicate plans to various responsibility center managers, to motivate managers to strive to achieve budget goals. Tools enable the actual operation of the business to be measured against the forecast. Lastly, tools establish the cost constraint for a project, program, on the other hand, if the figures diverge wildly from the budget, this sends an out of control signal, and the share price could suffer. Campaign planners incur two types of cost in any campaign, the first is the cost of human resource necessary to plan, the second type of expense that campaign planners incur is the hard cost of the campaign itself. A budget is a tool for an event director to predict with a reasonable accuracy whether the event will result in a profit. A budget can also be used as a pricing tool, there are two basic approaches or philosophies, when it comes to budgeting. One approach is telling you on mathematical models, and the other on people, the first school of thought believes that financial models, if properly constructed, can be used to predict the future. The focus is on variables, inputs and outputs, drivers, investments of time and money are devoted to perfecting these models, which are typically held in some type of financial spreadsheet application. The other school of thought holds that it’s not about models, no matter how sophisticated models can get, the best information comes from the people in the business. The focus is therefore in engaging the managers in the more fully in the budget process. The companies that adhere to this approach have their managers develop their own budgets, while many companies would say that they do both, in reality the investment of time and money falls squarely in one approach or the other. The budget of a government is a summary or plan of the revenues and expenditures of that government. There are three types of government budget, the operating or current budget, the capital or investment budget, the budget is prepared by the Treasury team led by the Chancellor of the Exchequer and is presented to Parliament by the Chancellor of the Exchequer on Budget Day

Construction site safety
–
Construction work is a dangerous land-based job. Some construction site jobs include, building houses, roads, workplaces and repair and this work includes many hazardous task and conditions such as working with height, excavation, noise, dust, power tools and equipment. The most common fatalities are caused by the four, falls, struck by object, electrocutions. Construction work has been increasing in developing and undeveloped countries over the past few years, with an increase in this type of work occupational fatalities have increased. Occupational fatalities are individuals that pass way while on the job or performing work related tasks, within the field of construction it is important to have safe construction sites. In 2014, the United States had 4,679 fatal occupational injuries, in the same year, fatal work injuries in construction and extraction occupations increased 5%. One in five workers died in 2014 were due to construction related deaths, Construction has about 6% of U. S. workers, but 17% of the fatalities - the largest number of fatalities reported for any industry sector. In 2002, there were 22,453 industrial accidents in Hong Kong, in the United Kingdom, the construction industry is responsible for 31% of fatalities at work and 10% of major workplace injuries. I In South Africa there are 150 fatalities and approximately 400 injuries each year related to construction sites, in Brazil, the incidence rate for all occupational fatalities is 3.6 per 100,000. The chart below contains more countries and the rate of construction site fatalities, the leading safety hazards on construction sites include, falls, caught between objects, electrocutions, and struck by objects. All four of those hazards have caused injuries and deaths throughout the world of construction sites, failures in hazard identification are often due to limited or improper training and supervision of the construction site workers. Examples of areas were there are limited training includes, tasks in design for safety, safety inspection, failure in any of these areas can result in an increased risk in exposing workers to harm in the construction environment. Falls are the cause of injury in the construction industry, is particularly for elder. Other countries have regulations and guidelines for fall protections to prevent injuries, therefore, it is important that construction sites are safe as possible for the workers. Motor vehicle crashes are another major safety hazard on construction sites and it is important to be cautious while operation motor vehicles or equipment on the site. Motor vehicles should have a brake system, emergency brake system. All vehicles must be equipped with a warning system if the operator chooses to use it. Vehicles must have windows and doors, power windshield wipers, and have a view of site from the rear window

Building material
–
Building material is any material which is used for construction purposes. Many naturally occurring substances, such as clay, rocks, sand, apart from naturally occurring materials, many man-made products are in use, some more and some less synthetic. They provide the make-up of habitats and structures including homes and these trends tend to increase the initial and long term economic, ecological, energy, and social costs of building materials. The initial economic cost of building materials is the purchase price and this is often what governs decision making about what materials to use. Sometimes people take into consideration the energy savings or durability of the materials, for example, an asphalt shingle roof costs less than a metal roof to install, but the metal roof will last longer so the lifetime cost is less per year. Some materials may require more care than others, maintaining costs specific to some materials may also influence the final decision. Risks when considering lifetime cost of a material is if the building is damaged such as by fire or wind, the cost of materials should be taken into consideration to bear the risk to buy combustive materials to enlarge the lifetime. It is said that, if it must be done, it must be done well, pollution costs can be macro and micro. An example of the aspect of pollution is the off-gassing of the building materials in the building or indoor air pollution. Red List building materials are found to be harmful. Also the carbon footprint, the set of greenhouse gas emissions produced in the life of the material. A life-cycle analysis also includes the reuse, recycling, or disposal of construction waste, two concepts in building which account for the ecological economics of building materials are green building and sustainable development. Initial energy costs include the amount of energy consumed to produce, deliver, the long term energy cost is the economic, ecological, and social costs of continuing to produce and deliver energy to the building for its use, maintenance, and eventual removal. The initial embodied energy of a structure is the energy consumed to extract, manufacture, deliver, install, social costs are injury and health of the people producing and transporting the materials and potential health problems of the building occupants if there are problems with the building biology. Aspects of fair trade and labor rights are social costs of building material manufacturing. These were variously named wikiups, lean-tos, and so forth, an extension on the brush building idea is the wattle and daub process in which clay soils or dung, usually cow, are used to fill in and cover a woven brush structure. This gives the more thermal mass and strength. Wattle and daub is one of the oldest building techniques, many older timber frame buildings incorporate wattle and daub as non load bearing walls between the timber frames

Megaproject
–
A megaproject is an extremely large-scale investment project. Megaprojects are temporary endeavours characterized by, large investment commitment, vast complexity, and long-lasting impact on the economy, the environment, the European Cooperation in Science and Technology categorises megaprojects as having extreme complexity and by a long record of poor delivery. Megaprojects attract a lot of attention because of substantial impacts on communities, environment, and budgets. Megaprojects can also be defined as initiatives that are physical, very expensive, Bent Flyvbjerg, a professor at the Saïd Business School of the University of Oxford says that globally, megaprojects make up 8 percent of total GDP. Megaprojects are often affected by corruptions leading to higher cost and lower benefit, according to Bent Flyvbjerg, as a general rule of thumb, “megaprojects” are measured in billions of dollars, “major projects” in hundreds of millions, and “projects” in millions and tens of millions. The logic on which many of the typical megaprojects are built is collective benefits, for electricity for everybody, road access. They may also serve as the means for opening frontiers, megaprojects have undergone a wide criticism for their top down planning processes and for their ill effects on certain communities.2 million farmers. In the 1970s, the Highway revolts involved urban activists opposing government plans to demolish buildings in freeway routes that would disadvantage the working class to benefit commuters. Anti-nuclear protests against proposed nuclear plants in the United States. However, just like the old megaprojects, the new ones also foreclose upon a variety of social practices, reproducing rather than resolving urban inequality. Because of their plethora of land uses these mega-projects inhibit the growth of oppositional and contestational practices, the collective benefits that are often the underlying logic of a mega-project, are here reduced to an individualized form of public benefit. Political sublime - the rapture politicians get from building monuments to themselves, economic sublime - the delight business people and trade unions get from making lots of money and jobs from megaprojects. Aesthethic sublime - the pleasure designers and people who appreciate good design get from building, using, proponents of infrastructure-based development advocate for funding large scale projects to create long-term economic benefits. Investing in megaprojects in order to stimulate the economy has been a popular policy measure since the economic crisis of the 1930s. Recent examples are the 2008–09 Chinese economic stimulus program, the 2008 European Union stimulus plan, megaprojects often raise capital based on expected returns - though projects often go overbudget and over time, and market conditions like commodity prices can change. Concern at cost overruns is often expressed by critics of megaprojects during the planning phase, if the megaproject is delivered in a country with relevant corruption the likelood and magnitude of having overbudgets increases. One of the most challenging aspects of megaprojects is obtaining sufficient funding

Thermal oxidizer
–
A thermal oxidizer is a process unit for air pollution control in many chemical plants that decomposes hazardous gases at a high temperature and releases them into the atmosphere. Thermal oxidizers are used to destroy hazardous air pollutants and volatile organic compounds from industrial air streams. These pollutants are generally hydrocarbon based and when destroyed via thermal combustion they are oxidized to form CO2. Three main factors in designing the effective thermal oxidizers are temperature, residence time, the temperature needs to be high enough to ignite the waste gas. Most organic compounds ignite at the temperature between 590 °C and 650 °C, to ensure near destruction of hazardous gases, most basic oxidizers are operated at much higher temperature levels. When catalyst is used, the temperature range may be lower. Residence time is to ensure there is enough time for the combustion reaction to occur. The turbulence factor is the mixture of air with the hazardous gases. The simplest technology of thermal oxidation is direct-fired thermal oxidizer, a process stream with hazardous gases is introduced into a firing box through or near the burner and enough residence time is provided to get the desired destruction removal efficiency of the VOCs. Most direct-fired thermal oxidizers operate at levels between 980 °C and 1,200 °C with air flow rates of 0.24 to 24 standard cubic meters per second. These are best applied where there is a high concentration of VOCs to act as the fuel source for complete combustion at the targeted operating temperature. One of today’s most widely accepted air pollution control technologies across industry is a thermal oxidizer. RTOs use a bed which is heated from a previous oxidation cycle to preheat the input gases to partially oxidize them. The preheated gases enter a chamber that is heated by an external fuel source to reach the target oxidation temperature which is in the range between 760 °C and 820 °C. The final temperature may be as high as 1,100 °C for applications that require maximum destruction, the air flow rates are 2.4 to 240 standard cubic meters per second. RTOs are very versatile and extremely efficient – thermal efficiency can reach 95% and they are regularly used for abating solvent fumes, odours, etc. from a wide range of industries. Regenerative Thermal Oxidizers are ideal in a range of low to high VOC concentrations up to 10 g/m3 solvent, there are currently many types Regenerative Thermal Oxidizer on the market with the capabitlity of 99. 5+% Volatile Organic Compound oxidisation or destruction efficiency. The ceramic heat exchanger in the towers can be designed for thermal efficiencies as high as 97+%, ventilation air methane thermal oxidizers are used to destroy methane in the exhaust air of underground coal mine shafts

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Civil engineering
–
Civil engineering is traditionally broken into a number of sub-disciplines. It is the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering, Civil engineering takes place in the public sector from municipal through to national governments, and in the private sector from individual homeowners through to international companies. Engineering has been an aspect of life since the beginnings of human existence, during this time, transportation became increasingly important leading to the development of the wheel and sailing. The construction of pyramids in Egypt were some of the first instances of large structure constructions, the Romans developed civil structures throughout their empire, including especially aqueducts, insulae, harbors, bridges, dams and roads. In the 18th century, the civil engineering was coined to incorporate all things civilian as opposed to military engineering. The first self-proclaimed civil engineer was John Smeaton, who constructed the Eddystone Lighthouse, in 1771 Smeaton and some of his colleagues formed the Smeatonian Society of Civil Engineers, a group of leaders of the profession who met informally over dinner. Though there was evidence of some meetings, it was little more than a social society. In 1818 the Institution of Civil Engineers was founded in London, the institution received a Royal Charter in 1828, formally recognising civil engineering as a profession. The first private college to teach engineering in the United States was Norwich University. The first degree in engineering in the United States was awarded by Rensselaer Polytechnic Institute in 1835. The first such degree to be awarded to a woman was granted by Cornell University to Nora Stanton Blatch in 1905, throughout ancient and medieval history most architectural design and construction was carried out by artisans, such as stonemasons and carpenters, rising to the role of master builder. Knowledge was retained in guilds and seldom supplanted by advances, structures, roads and infrastructure that existed were repetitive, and increases in scale were incremental. Brahmagupta, an Indian mathematician, used arithmetic in the 7th century AD, based on Hindu-Arabic numerals, Civil engineers typically possess an academic degree in civil engineering. The length of study is three to five years, and the degree is designated as a bachelor of engineering. The curriculum generally includes classes in physics, mathematics, project management, design, after taking basic courses in most sub-disciplines of civil engineering, they move onto specialize in one or more sub-disciplines at advanced levels. In most countries, a degree in engineering represents the first step towards professional certification. After completing a degree program, the engineer must satisfy a range of requirements before being certified. Once certified, the engineer is designated as a engineer, a chartered engineer

Electricity generation
–
Electricity generation is the process of generating electric power from sources of primary energy. For electric utilities, it is the first process in the delivery of electricity to consumers, the other processes as transmission, distribution, energy storage and recovery using pumped-storage methods are normally carried out by the electric power industry. Other energy sources include solar photovoltaics and geothermal power, the fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. This method is used today, electricity is generated by the movement of a loop of wire. Central power stations became practical with the development of alternating current power transmission, using power transformers to transmit power at high voltage. Electricity has been generated at central stations since 1882, the use of power-lines and power-poles have been significantly important in the distribution of electricity. There are seven fundamental methods of transforming other forms of energy into electrical energy. Static electricity, form the physical separation and transport of charge and it was the first form discovered and investigated, and the electrostatic generator is still used even in modern devices such as the Van de Graaff generator and MHD generators. In Electromagnetic induction, a generator, dynamo or alternator transforms kinetic energy into electricity. This is the most used form for generating electricity and is based on Faradays law and it can be experimented by rotating a magnet within closed loops of a conducting material. Almost all commercial electrical generation is done using electromagnetic induction, in mechanical energy forces a generator to rotate. Almost all electrical power on Earth is generated with a turbine, driven by wind, water, there are many different methods of developing mechanical energy, including heat engines, hydro, wind and tidal power. Most electric generation is driven by heat engines, the combustion of fossil fuels supplies most of the heat to these engines, with a significant fraction from nuclear fission and some from renewable sources. The modern steam turbine currently generates about 80% of the power in the world using a variety of heat sources. Power sources include, Steam Water is boiled by coal burned in a power plant. Nuclear fission heat created in a nuclear reactor creates steam, less than 15% of electricity is generated this way. Natural gas, turbines are directly by gases produced by combustion. Combined cycle are driven by steam and natural gas

Factory
–
Factories arose with the introduction of machinery during the Industrial Revolution when the capital and space requirements became too great for cottage industry or workshops. Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called glorified workshops, most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production. Large factories tend to be located with access to multiple modes of transportation, with some having rail, highway, factories may either make discrete products or some type of material continuously produced such as chemicals, pulp and paper, or refined oil products. Oil refineries have most of their equipment outdoors, discrete products may be final consumer goods, or parts and sub-assemblies which are made into final products elsewhere. Factories may be supplied parts from elsewhere or make them from raw materials, continuous production industries typically use heat or electricity to transform streams of raw materials into finished products. The term mill originally referred to the milling of grain, which usually used natural resources such as water or wind power until those were displaced by steam power in the 19th century. Because many processes like spinning and weaving, iron rolling, and paper manufacturing were originally powered by water, according to translations of Demosthenes and Herodotus, Naucratis was a, or the only, factory in the entirety of ancient Egypt. A source of 1983, states the largest factory production in ancient times was of 120 slaves within 4th century BC Athens, although The Cambridge Online Dictionary definition of factory states, a building or set of buildings where large amounts of goods are made using machines elsewhere. The wheel was invented circa 3000 BC, the spoked wheel c.2000 BC, the Iron Age began approximately 1200-1000 BC. However, other sources define machinery as a means of production, according to one text the water-mill was first made in 555 A. D. by Belisarius, although according to another they were known to Pliny the Elder and Vitruvius in the first century B. C. By the time of the 4th century A. D. mills with a capacity to grind 3 tonnes of cereal an hour, the Venice Arsenal provides one of the first examples of a factory in the modern sense of the word. Founded in 1104 in Venice, Republic of Venice, several hundred years before the Industrial Revolution, the Venice Arsenal apparently produced nearly one ship every day and, at its height, employed 16,000 people. One of the earliest factories was John Lombes water-powered silk mill at Derby, by 1746, an integrated brass mill was working at Warmley near Bristol. Raw material went in at one end, was smelted into brass and was turned into pans, pins, wire, housing was provided for workers on site. Josiah Wedgwood in Staffordshire and Matthew Boulton at his Soho Manufactory were other prominent early industrialists, the factory system began widespread use somewhat later when cotton spinning was mechanized. Richard Arkwright is the credited with inventing the prototype of the modern factory. After he patented his water frame in 1769, he established Cromford Mill, in Derbyshire, England, the factory system was a new way of organizing labour made necessary by the development of machines which were too large to house in a workers cottage. Working hours were as long as they had been for the farmer, overall, this practice essentially reduced skilled and unskilled workers to replaceable commodities

Petroleum industry
–
The petroleum industry includes the global processes of exploration, extraction, refining, transporting, and marketing of petroleum products. The largest volume products of the industry are fuel oil and gasoline, Petroleum is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, synthetic fragrances, and plastics. The industry is divided into three major components, upstream, midstream and downstream. Midstream operations are included in the downstream category. Petroleum is vital to many industries, and is of importance to the maintenance of industrial civilization in its current configuration, and thus is a critical concern for many nations. Oil accounts for a percentage of the world’s energy consumption, ranging from a low of 32% for Europe and Asia. Other geographic regions consumption patterns are as follows, South and Central America, Africa, the world consumes 30 billion barrels of oil per year, with developed nations being the largest consumers. The United States consumed 25% of the oil produced in 2007, the production, distribution, refining, and retailing of petroleum taken as a whole represents the worlds largest industry in terms of dollar value. Petroleum is a naturally occurring liquid found in rock formations and it consists of a complex mixture of hydrocarbons of various molecular weights, plus other organic compounds. It is generally accepted that oil is formed mostly from the carbon rich remains of ancient plankton after exposure to heat, Petroleum in an unrefined state has been utilized by humans for over 5000 years. Oil in general has been used since early history to keep fires ablaze. Its importance to the world economy evolved slowly, with oil used for lighting in the 19th century and wood. The Industrial Revolution generated an increasing need for energy which was met mainly by coal, Imperial Russia produced 3,500 tons of oil in 1825 and doubled its output by mid-century. Batum is renamed to Batumi in 1936, at the turn of the 20th century, Imperial Russias output of oil, almost entirely from the Apsheron Peninsula, accounted for half of the worlds production and dominated international markets. Nearly 200 small refineries operated in the suburbs of Baku by 1884, as a side effect of these early developments, the Apsheron Peninsula emerged as the worlds oldest legacy of oil pollution and environmental negligence. In 1846, Baku the first ever well drilled with percussion tools to a depth of 21 meters for oil exploration, in 1878, Ludvig Nobel and his Branobel company revolutionized oil transport by commissioning the first oil tanker and launching it on the Caspian Sea. Samuel Kier established Americas first oil refinery in Pittsburgh on Seventh avenue near Grant Street, one of the first modern oil refineries were built by Ignacy Łukasiewicz near Jasło, Poland in 1854–56. These were initially small as demand for refined fuel was limited, the refined products were used in artificial asphalt, machine oil and lubricants, in addition to Łukasiewiczs kerosene lamp

Telecommunication
–
Telecommunication is the transmission of signs, signals, messages, writings, images and sounds or intelligence of any nature by wire, radio, optical or other electromagnetic systems. Telecommunication occurs when the exchange of information between communication participants includes the use of technology and it is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation. Such transmission paths are divided into communication channels which afford the advantages of multiplexing. The term is used in its plural form, telecommunications. Early means of communicating over a distance included visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, other examples of pre-modern long-distance communication included audio messages such as coded drumbeats, lung-blown horns, and loud whistles. Zworykin, John Logie Baird and Philo Farnsworth, the word telecommunication is a compound of the Greek prefix tele, meaning distant, far off, or afar, and the Latin communicare, meaning to share. Its modern use is adapted from the French, because its use was recorded in 1904 by the French engineer. Communication was first used as an English word in the late 14th century, in the Middle Ages, chains of beacons were commonly used on hilltops as a means of relaying a signal. Beacon chains suffered the drawback that they could pass a single bit of information. One notable instance of their use was during the Spanish Armada, in 1792, Claude Chappe, a French engineer, built the first fixed visual telegraphy system between Lille and Paris. However semaphore suffered from the need for skilled operators and expensive towers at intervals of ten to thirty kilometres, as a result of competition from the electrical telegraph, the last commercial line was abandoned in 1880. Homing pigeons have occasionally used throughout history by different cultures. Pigeon post is thought to have Persians roots and was used by the Romans to aid their military, frontinus said that Julius Caesar used pigeons as messengers in his conquest of Gaul. The Greeks also conveyed the names of the victors at the Olympic Games to various cities using homing pigeons, in the early 19th century, the Dutch government used the system in Java and Sumatra. And in 1849, Paul Julius Reuter started a service to fly stock prices between Aachen and Brussels, a service that operated for a year until the gap in the telegraph link was closed. Sir Charles Wheatstone and Sir William Fothergill Cooke invented the telegraph in 1837. Also, the first commercial electrical telegraph is purported to have constructed by Wheatstone and Cooke. Both inventors viewed their device as an improvement to the electromagnetic telegraph not as a new device, samuel Morse independently developed a version of the electrical telegraph that he unsuccessfully demonstrated on 2 September 1837

North American Industry Classification System
–
An establishment is typically a single physical location, though administratively distinct operations at a single location may be treated as distinct establishments. Each establishment is classified to an industry according to the business activity taking place there. NAICS does not offer guidance on the classification of enterprises which are composed of multiple establishments, the NAICS numbering system employs a five or six-digit code at the most detailed industry level. The first five digits are generally the same in all three countries, the system is designed to be largely compatible with the United Nations Statistical Offices International Standard Industrial Classification system. NAICS versions are released five years. With the first version, released in 1997, NAICS offered enhanced coverage of the service sector, the 2002 revision accommodated significant changes in the Information Sector. The 2012 revision slightly reduced the number of industries and modified six sectors

Real property
–
The term is historic, arising from the now-discontinued form of action, which distinguished between real property disputes and personal property disputes. Personal property was, and continues to be, all property that is not real property, in countries with personal ownership of real property, civil law protects the status of real property in real-estate markets, where estate agents work in the market of buying and selling real estate. Scottish civil law calls real property heritable property, and in French-based law, the word real derives from Latin res, which was used in Middle English to mean relating to things, especially real property. In common law, real property was property that could be protected by some form of action, in contrast to personal property. As a result of this formalist approach, some things the common law deems to be land would not be classified as such by most modern legal systems, for example an advowson was real property. By contrast the rights of a leaseholder originate in personal actions, the law now broadly distinguishes between real property and personal property. The conceptual difference was between immovable property, which would transfer title along with the land, and movable property, bethell contains much historical information on the historical evolution of real property and property rights. To be of any value a claim to any property must be accompanied by a verifiable, in many cases, a description refers to one or more lots on a plat, a map of property boundaries kept in public records. The law recognizes different sorts of interests, called estates, in real property, the type of estate is generally determined by the language of the deed, lease, bill of sale, will, land grant, etc. through which the estate was acquired. Estates are distinguished by the property rights that vest in each. A party enjoying an estate is called a tenant, some important types of estates in land include, Fee simple, An estate of indefinite duration, that can be freely transferred. The most common and perhaps most absolute type of estate, under which the tenant enjoys the greatest discretion over the disposal of the property, conditional Fee simple, An estate lasting forever as long as one or more conditions stipulated by the deeds grantor does not occur. If such a condition does occur, the property reverts to the grantor, or a remainder interest is passed on to a third party, Fee tail, An estate which, upon the death of the tenant, is transferred to his or her heirs. Life estate, An estate lasting for the life of the grantee. If a life estate can be sold, a sale does not change its duration, a life estate pur autre vie is held by one person for the natural life of another person. Such an estate may arise if the life tenant sells her life estate to another. For example, an apartment-dweller with a one-year lease has an estate in her apartment. Lessees typically agree to pay a rent to the lessor

Ethiopia
–
Ethiopia, officially the Federal Democratic Republic of Ethiopia, is a country located in the Horn of Africa. It shares borders with Eritrea to the north and northeast, Djibouti and Somalia to the east, Sudan and South Sudan to the west, and Kenya to the south. With nearly 100 million inhabitants, Ethiopia is the most populous landlocked country in the world and it occupies a total area of 1,100,000 square kilometres, and its capital and largest city is Addis Ababa. Some of the oldest evidence for modern humans has been found in Ethiopia. It is widely considered as the region from modern humans first set out for the Middle East. According to linguists, the first Afroasiatic-speaking populations settled in the Horn region during the ensuing Neolithic era, tracing its roots to the 2nd millennium BC, Ethiopia was a monarchy for most of its history. During the first centuries AD, the Kingdom of Aksum maintained a unified civilization in the region, subsequently, many African nations adopted the colors of Ethiopias flag following their independence. It was the first independent African member of the 20th-century League of Nations, Ethiopias ancient Geez script, also known as Ethiopic, is one of the oldest alphabets still in use in the world. The Ethiopian calendar, which is seven years and three months behind the Gregorian calendar, co-exists alongside the Borana calendar. A slight majority of the population adheres to Christianity, while around a third follows Islam, the country is the site of the Migration to Abyssinia and the oldest Muslim settlement in Africa at Negash. A substantial population of Ethiopian Jews, known as Bete Israel, resided in Ethiopia until the 1980s, Ethiopia is a multilingual nation with around 80 ethnolinguistic groups, the four largest of which are the Oromiffa, Amhara, Somali, and Tigrayans. Most people in the country speak Afroasiatic languages of the Cushitic or Semitic branches, additionally, Omotic languages are spoken by ethnic minority groups inhabiting the southern regions. Nilo-Saharan languages are spoken by the nations Nilotic ethnic minorities. Ethiopia is the place of origin for the coffee bean which originated from the place called Kefa and it is a land of natural contrasts, with its vast fertile West, jungles, and numerous rivers, and the worlds hottest settlement of Dallol in its north. The Ethiopian Highlands are Africas largest continuous mountain ranges, and Sof Omar Caves contain Africas largest cave, Ethiopia has the most UNESCO World Heritage Sites in Africa. Ethiopia is one of the members of the UN, the Group of 24, the Non-Aligned Movement, G-77. In the 1970s and 1980s, Ethiopia suffered from civil wars, the country has begun to recover recently however, and now has the largest economy in East Africa and Central Africa. According to Global Fire Power, Ethiopia has the 42nd most powerful military in the world, the origin of the word Ethiopia is uncertain

Dire Dawa
–
Dire Dawa is one of two chartered cities in Ethiopia. It is divided administratively into two woredas, the city proper and the woreda of Gurgura. According to the Futuh Al Habasha, Conquest of Abyssinia, the area or settlement was only called Dir after the major Somali clan around 5 centuries ago. Dire Dawa lies in the part of the nation, on the Dechatu River. At a latitude and longitude of 9°36′N 41°52′E, it is the second largest city in Ethiopia, the city is an industrial centre, home to several markets and the Aba Tenna Dejazmach Yilma International Airport. Haramaya University is 40 kilometres away, the company was already having financial difficulty and Ilg received permission from Emperor Menelik II not to complete the expensive climb to nearby Harar at its higher elevation. Instead, Addis Harar served as the terminus for the line linking the area with the French port at Djibouti, harars governor Ras Makonnen then linked the two cities with a new road. Dire Dawas first governor was Ato Mersha Nahusenay, who was instrumental in the construction of the first railway. The imperial railway company played a key role in the development of the city, particularly Gezira. The Dire Dawa-Harar road was improved in 1928, shortening the time to only a few hours. The Italian army entered the country from the colonies of Eritrea in the north, following all major engagements of the war, Dire Dawa was the location of the meeting of the two Italian forces. They were met by two French armed cars, the railway remained under French administration and they had remained to protect the French interests. The next day, the first train under Italian control left Addis Ababa, it brought Italys 46th Infantry Regiment, the occupation of the town was more or less a formality, although resistance fighters known as Arbegnoch continued to operate throughout the conflict. It was officially known by its Italian spelling Dire Daua during the occupation, following the restoration of the empire in 1941, Dire Dawa was among the early provincial towns to have its own soccer league. Around 1947, their team—the Taffari—participated in the Ethiopian Championship series and that same year, the Railroad Workers Syndicate of Dire Dawa, a labor union, was formed for welfare purposes. In 1955, a public system was installed in the central square to receive. The Ethiopian revolution affected the city in many ways, starting March 1974, there was some worker unrest, six people were wounded when police opened fire on demonstrating railwaymen and students on 17 April. Many Europeans, Yemeni Arabs, and Indians left Dire Dawa, on 3 February 1975, the Derg announced that the Cotton Company of Ethiopia was among 14 textile enterprises to be fully nationalized

Building code
–
A building code is a set of rules that specify the standards for constructed objects such as buildings and nonbuilding structures. Buildings must conform to the code to obtain planning permission, usually from a local council, the main purpose of building codes is to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a jurisdiction when formally enacted by the appropriate governmental or private authority. Codes regulating the design and construction of structures where adopted into law, examples of building codes began in ancient times. In the USA the main codes are the International Commercial or Residential Code, electrical codes and plumbing, fifty states and the District of Columbia have adopted the I-Codes at the state or jurisdictional level. In Canada, national model codes are published by the National Research Council of Canada, the practice of developing, approving, and enforcing building codes varies considerably among nations. In some countries building codes are developed by the government agencies or quasi-governmental standards organizations, such codes are known as the national building codes. In other countries, where the power of regulating construction and fire safety is vested in local authorities, model building codes have no legal status unless adopted or adapted by an authority having jurisdiction. The developers of model codes urge public authorities to reference model codes in their laws, ordinances, regulations, when referenced in any of these legal instruments, a particular model code becomes law. This practice is known as adoption by reference, there are instances when some local jurisdictions choose to develop their own building codes. At some point in all major cities in the United States had their own building codes. However, due to increasing complexity and cost of developing building regulations. For example, in 2008 New York City abandoned its proprietary 1968 New York City Building Code in favor of a version of the International Building Code. The City of Chicago remains the only municipality in America that continues to use a building code the city developed on its own as part of the Municipal Code of Chicago, in Europe, the Eurocode is a pan-European building code that has superseded the older national building codes. Each country now has National Annexes to localize the contents of the Eurocode, similarly, in India, each municipality and urban development authority has its own building code, which is mandatory for all construction within their jurisdiction. All these local building codes are variants of a National Building Code, Building codes have a long history. The earliest known written building code is included in the Code of Hammurabi, the book of Deuteronomy in the Hebrew Bible stipulated that parapets must be constructed on all houses to prevent people from falling off. The Laws of the Indies were passed in the 1680s by the Spanish Crown to regulate the urban planning for colonies throughout Spains worldwide imperial possessions, the first systematic national building standard was established with the London Building Act of 1844

Lumber
–
Lumber, or timber is wood that has been processed into beams and planks, a stage in the process of wood production. Lumber may also refer to currently un-needed furniture, as in Lumber room, or an awkward gait, ultimately derived from the look of unfashionable, Lumber may be supplied either rough-sawn, or surfaced on one or more of its faces. Besides pulpwood, rough lumber is the raw material for furniture-making and it is available in many species, usually hardwoods, but it is also readily available in softwoods, such as white pine and red pine, because of their low cost. Lumber is mainly used for structural purposes but has other uses as well. It is classified more commonly as a softwood than as a hardwood, in Australia, Ireland, New Zealand and Britain, the term timber describes sawn wood products, such as floor boards. In the United States and Canada, generally timber describes standing or felled trees, before they are milled into boards, Timber there also describes sawn lumber not less than 5 inches in its smallest dimension. The latter includes the often partly finished lumber used in timber-frame construction, remanufactured lumber is the result of secondary or tertiary processing/cutting of previously milled lumber. Specifically, it is cut for industrial or wood-packaging use. Lumber is cut by ripsaw or resaw to create dimensions that are not usually processed by a primary sawmill, resawing is the splitting of 1-inch through 12-inch hardwood or softwood lumber into two or more thinner pieces of full-length boards. For example, splitting a ten-foot 2×4 into two ten-foot 1×4s is considered resawing, structural lumber may also be produced from recycled plastic and new plastic stock. Its introduction has been opposed by the forestry industry. Blending fiberglass in plastic lumber enhances its strength, durability, logs are converted into timber by being sawn, hewn, or split. Sawing with a rip saw is the most common method, because sawing allows logs of lower quality, with grain and large knots. There are various types of sawing, Plain sawn —A log sawn through without adjusting the position of the log, quarter sawn and rift sawn—These terms have been confused in history but generally mean lumber sawn so the annual rings are reasonably perpendicular to the sides of the lumber. Boxed heart—The pith remains within the piece with some allowance for exposure, heart center—the center core of a log. Free of heart center —A side-cut timber without any pith, free of knots —No knots are present. Dimensional lumber is lumber that is cut to standardized width and depth, carpenters extensively use dimensional lumber in framing wooden buildings. Common sizes include 2×4, 2×6, and 4×4, the length of a board is usually specified separately from the width and depth

House
–
Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space, most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room, in traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock may share part of the house with humans. The social unit that lives in a house is known as a household, most commonly, a household is a family unit of some kind, although households may also be other social groups, such as roommates or, in a rooming house, unconnected individuals. Some houses only have a space for one family or similar-sized group. A house may be accompanied by outbuildings, such as a garage for vehicles or a shed for gardening equipment, a house may have a backyard or frontyard, which serve as additional areas where inhabitants can relax or eat. The English word house derives directly from the Old English Hus meaning dwelling, shelter, home, house, the house itself gave rise to the letter B through an early Proto-Semitic hieroglyphic symbol depicting a house. The symbol was called bayt, bet or beth in various related languages, and became beta, ideally, architects of houses design rooms to meet the needs of the people who will live in the house. Such designing, known as design, has become a popular subject in universities. Feng shui can also mean the aura in or around a dwelling, making it comparable to the real-estate sales concept of indoor-outdoor flow, the square footage of a house in the United States reports the area of living space, excluding the garage and other non-living spaces. The square metres figure of a house in Europe reports the area of the enclosing the home. The number of floors or levels making up the house can affect the square footage of a home, many houses have several large rooms with specialized functions and several very small rooms for other various reasons. These may include an area, a sleeping area, and separate or combined washing. Some larger properties may also feature such as a spa room, indoor pool, indoor basketball court. In traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock often share part of the house with human beings, most conventional modern houses will at least contain a bedroom, bathroom, kitchen or cooking area, and a living room. Little is known about the earliest origin of the house and its interior, roman architect Vitruvius theories have claimed the first form of architecture as a frame of timber branches finished in mud, also known as the primitive hut. Philip Tabor later states the contribution of 17th century Dutch houses as the foundation of houses today, as far as the idea of the home is concerned, the home of the home is the Netherlands

Economies of scale
–
Often operational efficiency is also greater with increasing scale, leading to lower variable cost as well. Economies of scale apply to a variety of organizational and business situations and at levels, such as a business or manufacturing unit. Some economies of scale, such as capital cost of manufacturing facilities and friction loss of transportation, the economic concept dates back to Adam Smith and the idea of obtaining larger production returns through the use of division of labor. Diseconomies of scale are the opposite, Economies of scale often have limits, such as passing the optimum design point where costs per additional unit begin to increase. Common limits include exceeding the nearby raw material supply, such as wood in the lumber, pulp, a common limit for low cost per unit weight commodities is saturating the regional market, thus having to ship product uneconomical distances. Other limits include using energy less efficiently or having a defect rate. Large producers are usually efficient at long runs of a product grade and they will therefore avoid specialty grades even though they have higher margins. Often smaller manufacturing facilities remain viable by changing from commodity grade production to specialty products, the simple meaning of economies of scale is doing things more efficiently with increasing size or speed of operation. Economies of scale often originate with fixed capital, which is lowered per unit of production as design capacity increases, in wholesale and retail distribution, increasing the speed of operations, such as order fulfillment, lowers the cost of both fixed and working capital. Other common sources of economies of scale are purchasing, managerial, financial, marketing, each of these factors reduces the long run average costs of production by shifting the short-run average total cost curve down and to the right. Economies of the scale is a concept that may explain real world phenomena such as patterns of international trade or the number of firms in a market. The exploitation of economies of scale helps explain why companies grow large in some industries, a lone car maker may be profitable, but even more so if they exported cars to global markets in addition to selling to the local market. Economies of scale play a role in a natural monopoly. There is a distinction between two types of economies of scale, internal and external, conversely, an industry exhibits an external economy of scale when costs drop due to the introduction of more firms, thus allowing for more efficient use of specialized services and machinery. Instead, he believes that economies will come from improving the flow of a service, in trying to manage and reduce unit costs, firms often raise total costs by creating failure demand. This law has an effect on the capital cost of such things as buildings, factories, pipelines, ships. In structural engineering, the strength of beams increases with the cube of the thickness, drag loss of vehicles like aircraft or ships generally increases less than proportional with increasing cargo volume, although the physical details can be quite complicated. Therefore, making them larger usually results in fuel consumption per ton of cargo at a given speed

Construction waste
–
Construction waste consists of unwanted material produced directly or incidentally by the construction or industries. Construction waste may lead, asbestos, or other hazardous substances. Much building waste is made up of such as bricks, concrete. Since considerable variability exists between construction sites, there is opportunity for reducing this waste. Some certain components of construction such as plasterboard are hazardous once landfilled. Plasterboard is broken down in landfill conditions releasing hydrogen sulfide, a toxic gas, there is the potential to recycle many elements of construction waste. Often roll-off containers are used to transport the waste, rubble can be crushed and reused in construction projects. Waste wood can also be recovered and recycled, in England all personnel performing builders or construction waste clearance are required by law to be working for a CIS registered business. Government or local authorities often make rules about how much waste should be sorted before it is hauled away to landfills or other treatment facilities. Some hazardous materials may not be moved, before the authorities have ascertained that safety guidelines, among their concerns would be the proper handling and disposal of such toxic elements as lead, asbestos or radioactive materials. The government pays tipping fee to the company for waste removal as an incentive to relieve the stress on the environment, the construction waste is recycled to several sizes of gravels that can be reused in construction beside the screened sand can be used in ancillary construction uses.

McKinsey & Company
–
McKinsey & Company is a worldwide management consulting firm. It conducts qualitative and quantitative analysis in order to evaluate management decisions across the public, widely considered the most prestigious management consultancy, McKinseys clientele includes 80% of the worlds largest corporations, and an extensive list of governments and non-profit organizations. More current and former Fortune 500 C. E. O. s are alumni of McKinsey than of any other company, James P. Gorman, and many more. McKinsey publishes the McKinsey Quarterly, funds the McKinsey Global Institute research organization, publishes reports on management topics and its practices of confidentiality, influence on business practices, and corporate culture have experienced a polarizing reception. McKinsey was founded in 1926 by James O. McKinsey in order to apply accounting principles to management, McKinsey died in 1937, and the firm was restructured several times, with the modern-day McKinsey & Company emerging in 1939. Marvin Bower is credited with establishing McKinseys culture and practices in the 1930s based on the principles he experienced as a lawyer, the firm developed an up or out policy, where consultants who are not promoted are asked to leave. McKinsey was the first management consultancy to hire recent college graduates, in the 1980s and 1990s, the firm expanded internationally and established new practice areas. It had 88 staff in 1951 and 7,700 by the early 2000s, McKinseys consulting has helped to establish many of the norms in business and contributed to many of the major successes and failures in business in the modern era. McKinsey & Company was founded under the name James O. McKinsey & Company in 1926 by James McKinsey and he conceived the idea after witnessing inefficiencies in military suppliers while working for the U. S. Army Ordnance Department. The firm called itself an accounting and management firm and started out giving consulting on using accounting principles as a management tool, Mr. McKinseys first partners were Tom Kearney, hired in 1929, and Marvin Bower, hired in 1933. In its first few years, the firm grew quickly and began developing rapport among corporations, in 1935, Mr. McKinsey left the firm temporarily to serve as the Chairman and CEO of client Marshall Fields as it implemented the restructuring plan created by his firm. A Wellington project that accounted for 55 percent of McKinsey, Wellington & Companys billings was about to expire and Kearney, Bower wanted to expand nationally and hire young business school graduates, whereas Kearney wanted to stay in Chicago and hire experienced accountants. Additionally, in 1937 James O. McKinsey died after catching pneumonia and this led to the division of McKinsey, Wellington & Company in 1939. The accounting practice returned to Scovell, Wellington & Company, while the management engineering practice was split into McKinsey & Company, the New York office purchased exclusive rights to the McKinsey name in 1946. McKinsey & Company grew quickly in the 1940s and 50s, especially in Europe and it had 88 staff in 1951 and more than 200 by the 1960s, including 37 in London by 1966. In the same year, McKinsey had six offices in major US cities like San Francisco, Los Angeles and these foreign offices were primarily in Europe, such as in London, Paris, Amsterdam, as well as in Melbourne. By this time, one third of the companys revenues originated from its European offices, guy Crockett stepped down as managing director in 1950, and Marvin Bower was elected in his place. McKinseys profit-sharing, executive and planning committees were formed in 1951, the organizations client base expanded especially among governments, defense contractors, bluechip companies and military organizations in the post-World War II era
