Domestication is a sustained multi-generational relationship in which one group of organisms assumes a significant degree of influence over the reproduction and care of another group to secure a more predictable supply of resources from that second group. Charles Darwin recognized the small number of traits that made domestic species different from their wild ancestors, he was the first to recognize the difference between conscious selective breeding in which humans directly select for desirable traits, unconscious selection where traits evolve as a by-product of natural selection or from selection on other traits. There is a genetic difference between wild populations. There is such a difference between the domestication traits that researchers believe to have been essential at the early stages of domestication, the improvement traits that have appeared since the split between wild and domestic populations. Domestication traits are fixed within all domesticates, were selected during the initial episode of domestication of that animal or plant, whereas improvement traits are present only in a proportion of domesticates, though they may be fixed in individual breeds or regional populations.
The dog was the first domesticated vertebrate, was established across Eurasia before the end of the Late Pleistocene era, well before cultivation and before the domestication of other animals. The archaeological and genetic data suggest that long-term bidirectional gene flow between wild and domestic stocks – including donkeys, horses and Old World camelids, goats and pigs – was common. Given its importance to humans and its value as a model of evolutionary and demographic change, domestication has attracted scientists from archaeology, anthropology, zoology and the environmental sciences. Among birds, the major domestic species today is the chicken, important for meat and eggs, though economically valuable poultry include the turkey and numerous other species. Birds are widely kept as cagebirds, from songbirds to parrots; the longest established invertebrate domesticates are the silkworm. Terrestrial snails are raised for food, while species from several phyla are kept for research, others are bred for biological control.
The domestication of plants began at least 12,000 years ago with cereals in the Middle East, the bottle gourd in Asia. Agriculture developed in at least 11 different centres around the world, domesticating different crops and animals. Domestication, from the Latin domesticus,'belonging to the house', is "a sustained multi-generational, mutualistic relationship in which one organism assumes a significant degree of influence over the reproduction and care of another organism in order to secure a more predictable supply of a resource of interest, through which the partner organism gains advantage over individuals that remain outside this relationship, thereby benefitting and increasing the fitness of both the domesticator and the target domesticate." This definition recognizes both the biological and the cultural components of the domestication process and the impacts on both humans and the domesticated animals and plants. All past definitions of domestication have included a relationship between humans with plants and animals, but their differences lay in, considered as the lead partner in the relationship.
This new definition recognizes a mutualistic relationship. Domestication has vastly enhanced the reproductive output of crop plants and pets far beyond that of their wild progenitors. Domesticates have provided humans with resources that they could more predictably and securely control and redistribute, the advantage that had fueled a population explosion of the agro-pastoralists and their spread to all corners of the planet. Houseplants and ornamentals are plants domesticated for aesthetic enjoyment in and around the home, while those domesticated for large-scale food production are called crops. Domesticated plants deliberately altered or selected for special desirable characteristics are cultigens. Animals domesticated for home companionship are called pets, while those domesticated for food or work are known as livestock; this biological mutualism is not restricted to humans with domestic crops and livestock but is well-documented in nonhuman species among a number of social insect domesticators and their plant and animal domesticates, for example the ant–fungus mutualism that exists between leafcutter ants and certain fungi.
Domestication syndrome is the suite of phenotypic traits arising during domestication that distinguish crops from their wild ancestors. The term is applied to vertebrate animals, includes increased docility and tameness, coat color changes, reductions in tooth size, changes in craniofacial morphology, alterations in ear and tail form, more frequent and nonseasonal estrus cycles, alterations in adrenocorticotropic hormone levels, changed concentrations of several neurotransmitters, prolongations in juvenile behavior, reductions in both total brain size and of particular brain regions; the domestication of animals and plants began with the wolf at least 15,000 years before present, which led to a rapid shift in the evolution and demography of both humans and numerous species of animals and plants. The sudden appearance of the domestic dog in the archaeological record was followed by livestock and crop domestication, the transition of humans from foraging to farming in different places and times across the planet.
Around 10,000 YBP, a new way of life emerged for humans through the management and exploitation of plant and an
The three-age system is the categorization of history into time periods divisible by three. In history and physical anthropology, the three-age system is a methodological concept adopted during the 19th century by which artifacts and events of late prehistory and early history could be ordered into a recognizable chronology, it was developed by C. J. Thomsen, director of the Royal Museum of Nordic Antiquities, Copenhagen, as a means to classify the museum’s collections according to whether the artifacts were made of stone, bronze, or iron; the system first appealed to British researchers working in the science of ethnology who adopted it to establish race sequences for Britain's past based on cranial types. Although the craniological ethnology that formed its first scholarly context holds no scientific value, the relative chronology of the Stone Age, the Bronze Age and the Iron Age is still in use in a general public context, the three ages remain the underpinning of prehistoric chronology for Europe, the Mediterranean world and the Near East.
The structure reflects the cultural and historical background of Mediterranean Europe and the Middle East and soon underwent further subdivisions, including the 1865 partitioning of the Stone Age into Paleolithic and Neolithic periods by John Lubbock. It is, however, of little or no use for the establishment of chronological frameworks in sub-Saharan Africa, much of Asia, the Americas and some other areas and has little importance in contemporary archaeological or anthropological discussion for these regions; the concept of dividing pre-historical ages into systems based on metals extends far back in European history originated by Lucretius in the first century BC. But the present archaeological system of the three main ages—stone and iron—originates with the Danish archaeologist Christian Jürgensen Thomsen, who placed the system on a more scientific basis by typological and chronological studies, at first, of tools and other artifacts present in the Museum of Northern Antiquities in Copenhagen.
He used artifacts and the excavation reports published or sent to him by Danish archaeologists who were doing controlled excavations. His position as curator of the museum gave him enough visibility to become influential on Danish archaeology. A well-known and well-liked figure, he explained his system in person to visitors at the museum, many of them professional archaeologists. In his poem and Days, the ancient Greek poet Hesiod between 750 and 650 BC, defined five successive Ages of Man: 1. Golden, 2. Silver, 3. Bronze, 4. Heroic and 5. Iron. Only the Bronze Age and the Iron Age are based on the use of metal:... Zeus the father created the third generation of mortals, the age of bronze... They were terrible and strong, the ghastly action of Ares was theirs, violence.... The weapons of these men were bronze, of bronze their houses, they worked as bronzesmiths. There was not yet any black iron. Hesiod knew from the traditional poetry, such as the Iliad, the heirloom bronze artifacts that abounded in Greek society, that before the use of iron to make tools and weapons, bronze had been the preferred material and iron was not smelted at all.
He did not continue the manufacturing metaphor, but mixed his metaphors, switching over to the market value of each metal. Iron was cheaper than bronze, so there must have been a silver age, he portrays a sequence of metallic ages. Each age has less of a moral value than the preceding. Of his own age he says: "And I wish that I were not any part of the fifth generation of men, but had died before it came, or had been born afterward." The moral metaphor of the ages of metals continued. Lucretius, replaced moral degradation with the concept of progress, which he conceived to be like the growth of an individual human being; the concept is evolutionary:. Everything must pass through successive phases. Nothing remains. Everything is on the move. Everything is transformed by nature and forced into new paths... The Earth passes through successive phases, so that it can no longer bear what it could, it can now what it could not before; the Romans believed that the species of animals, including humans, were spontaneously generated from the materials of the Earth, because of which the Latin word mater, "mother", descends to English-speakers as matter and material.
In Lucretius the Earth is Venus, to whom the poem is dedicated in the first few lines. She brought forth humankind by spontaneous generation. Having been given birth as a species, humans must grow to maturity by analogy with the individual; the different phases of their collective life are marked by the accumulation of customs to form material civilization: The earliest weapons were hands and teeth. Next came stones and branches wrenched from trees, fire and flame as soon as these were discovered. Men learnt to use tough iron and copper. With copper they tilled the soil. With copper they whipped up the clashing waves of war... By slow degrees the iron sword came to the fore. Lucretius envisioned a pre-technological human, "far tougher than the men of today... They lived out their lives in the fashion of wild beasts roaming at large." The next stage was the use of huts, clothing and the family. City-states and citadels followed them. Lucretius supposes that the initial
In archaeology a section is a view in part of the archaeological sequence showing it in the vertical plane, as a cross section, thereby illustrating its profile and stratigraphy. This may make it easier to interpret as it developed over time. Half-sectioning is the usual method whereby one half of a feature is excavated and the remainder left in situ. Large linear features may be sectioned at intervals along their lengths. Sectioning has fallen out of favour in some schools of practice because detail is missed in section, important to the phasing of the site. Examples of detail, revealed poorly "in section" include gravel or thin cobbled surfaces; the main problem with sections is the arbitrary location of their placement may "clip" or "just miss" contexts that reveal a different story form the one interpreted by the archaeologist. For instance thin liner features such as wheel ruts may be sectioned at an oblique angle giving the impression of a wider feature as the eye and brain tends to assume that features revealed in section have been cut at right angles to the orientation the feature was made.
Numerous other false readings of sections are possible to the unwary, this is why excavation "in plan" is now preferred. Sections are used in conjunction with two-dimensional excavation by plan to determine the origin of archaeological remains. For recording purposes sections are drawn at a scale of 1:10 or 1:20 with their height related to the site benchmark which in turn is related back to a level fixed at some agreed standard of sea level. Orientation should be recorded. If the section is instructive a photographic record may be made. Sections may be employed in excavation in temporary fashion as a form of stratigraphic control so as to ascertain the relationship between two or more contexts which may be better examined by the use of a section. Once a relationship is established contexts can be removed from site in the reverse order they arrived in accordance with the stratigraphic excavation and the creation of a Harris matrix for the sequence being investigated, it is up to the archaeologist on site to determine the best local on site strategy for excavating deposits, be it "in section" or "in plan".
In this regard the modern archaeologist uses sectioning as a tool for understanding the site stratigraphically during excavation rather than as an end goal in recording it. These caveats aside sections remain a powerful tool for archaeological investigation. A revival of digging in section with machines has occurred in recent years by a proliferation of limited time constrained development led excavations. Sometimes called digging by quadrant this special case is a procedure for excavating circular features mounds and, Deposits are excavated from four quarters of the feature, starting with two diagonally opposite quadrants and ending with the other two; the quadrants are offset, so that the outer balk of one is continuous with the outer face of its opposite, going through the center of the feature. After the recording of the sections, the balks may be removed and the rest of the feature excavated; the advantage of quarter sectioning is it allows a look at two complete cross-sections while still allowing excavation in plan thus allowing a better interpretation of the stratigraphy of the site.
The merits of this sectioning and balk creation are disputed.

An artifact, or artefact, is something made or given shape by humans, such as a tool or a work of art an object of archaeological interest. In archaeology, the word has become a term of particular nuance and is defined as: an object recovered by archaeological endeavor, which may be a cultural artifact having cultural interest. However, modern archaeologists take care to distinguish material culture from ethnicity, more complex, as expressed by Carol Kramer in the dictum "pots are not people". Examples include stone tools, pottery vessels, metal objects such as weapons, items of personal adornment such as buttons and clothing. Bones that show signs of human modification are examples. Natural objects, such as fire cracked rocks from a hearth or plant material used for food, are classified by archeologists as ecofacts rather than as artifacts. Artifacts can come from any archaeological context or source such as: Buried along with a body From any feature such as a midden or other domestic setting Votive offerings Hoards, such as at wellsArtifacts are distinguished from the main body of the archaeological record such as stratigraphic features, which are non-portable remains of human activity, such as hearths, deposits, trenches or similar remains, from biofacts or ecofacts, which are objects of archaeological interest made by other organisms, such as seeds or animal bone.
Natural objects that humans have moved but not changed are called manuports. Examples include seashells moved inland, or rounded pebbles placed away from the water action that made them; these distinctions are blurred. For instance, a bone removed from an animal carcass is a biofact, but a bone carved into a useful implement is an artifact. There can be debate over early stone objects that could be either crude artifacts or occurring and happen to resemble early objects made by early humans or Homo sapiens, it can be difficult to distinguish the differences between actual man-made lithic artifacts and geofacts – occurring lithics that resemble man-made tools. It is possible to authenticate artifacts by examining the general characteristics attributed to man-made tools and local characteristics of the site. In ethnography and archaeology, a category of "ancestral artifact" has been proposed, defined as "any object of natural raw material made by a people following a lifestyle based on foraging and/or basic agriculture or pastoralism".

The Neolithic, the final division of the Stone Age, began about 12,000 years ago when the first development of farming appeared in the Epipalaeolithic Near East, in other parts of the world. The division lasted until the transitional period of the Chalcolithic from about 6,500 years ago, marked by the development of metallurgy, leading up to the Bronze Age and Iron Age. In Northern Europe, the Neolithic lasted until about 1700 BC, while in China it extended until 1200 BC. Other parts of the world remained broadly in the Neolithic stage of development, although this term may not be used, until European contact; the Neolithic comprises a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops and of domesticated animals. The term Neolithic derives from the Greek νέος néos, "new" and λίθος líthos, "stone" meaning "New Stone Age"; the term was coined by Sir John Lubbock in 1865 as a refinement of the three-age system. Following the ASPRO chronology, the Neolithic started in around 10,200 BC in the Levant, arising from the Natufian culture, when pioneering use of wild cereals evolved into early farming.
The Natufian period or "proto-Neolithic" lasted from 12,500 to 9,500 BC, is taken to overlap with the Pre-Pottery Neolithic of 10,200–8800 BC. As the Natufians had become dependent on wild cereals in their diet, a sedentary way of life had begun among them, the climatic changes associated with the Younger Dryas are thought to have forced people to develop farming. By 10,200–8800 BC farming communities had arisen in the Levant and spread to Asia Minor, North Africa and North Mesopotamia. Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. Early Neolithic farming was limited to a narrow range of plants, both wild and domesticated, which included einkorn wheat and spelt, the keeping of dogs and goats. By about 6900–6400 BC, it included domesticated cattle and pigs, the establishment of permanently or seasonally inhabited settlements, the use of pottery. Not all of these cultural elements characteristic of the Neolithic appeared everywhere in the same order: the earliest farming societies in the Near East did not use pottery.
In other parts of the world, such as Africa, South Asia and Southeast Asia, independent domestication events led to their own regionally distinctive Neolithic cultures, which arose independently of those in Europe and Southwest Asia. Early Japanese societies and other East Asian cultures used pottery before developing agriculture. In the Middle East, cultures identified as Neolithic began appearing in the 10th millennium BC. Early development occurred from there spread eastwards and westwards. Neolithic cultures are attested in southeastern Anatolia and northern Mesopotamia by around 8000 BC; the prehistoric Beifudi site near Yixian in Hebei Province, contains relics of a culture contemporaneous with the Cishan and Xinglongwa cultures of about 6000–5000 BC, neolithic cultures east of the Taihang Mountains, filling in an archaeological gap between the two Northern Chinese cultures. The total excavated area is more than 1,200 square yards, the collection of neolithic findings at the site encompasses two phases.
The Neolithic 1 period began around 10,000 BC in the Levant. A temple area in southeastern Turkey at Göbekli Tepe, dated to around 9500 BC, may be regarded as the beginning of the period; this site was developed by nomadic hunter-gatherer tribes, as evidenced by the lack of permanent housing in the vicinity, may be the oldest known human-made place of worship. At least seven stone circles, covering 25 acres, contain limestone pillars carved with animals and birds. Stone tools were used by as many as hundreds of people to create the pillars, which might have supported roofs. Other early PPNA sites dating to around 9500–9000 BC have been found in Jericho, West Bank, Gilgal in the Jordan Valley, Byblos, Lebanon; the start of Neolithic 1 overlaps the Heavy Neolithic periods to some degree. The major advance of Neolithic 1 was true farming. In the proto-Neolithic Natufian cultures, wild cereals were harvested, early seed selection and re-seeding occurred; the grain was ground into flour. Emmer wheat was domesticated, animals were herded and domesticated.
In 2006, remains of figs were discovered in a house in Jericho dated to 9400 BC. The figs are of a mutant variety that cannot be pollinated by insects, therefore the trees can only reproduce from cuttings; this evidence suggests that figs were the first cultivated crop and mark the invention of the technology of farming. This occurred centuries before the first cultivation of grains. Settlements became more permanent, with circular houses, much like those of the Natufians, with single rooms. However, these houses were for the first time made of mudbrick; the settlement had a surrounding stone wall and a stone tower. The wall served as protection from nearby groups, as protection from floods, or to keep animals penned; some of the enclosures suggest grain and meat storage. The Neolithic 2 began around 8800 BC according to the ASPRO chronology in the Levant; as with the PPNA dates, there are two versions from the same laboratories noted above. This system of terminology, however, is not convenient for southeast Anatolia and settlements of the middle Anatolia basin.
A settlement of 3,000 inhabitants was found in th
History of agriculture
The history of agriculture records the domestication of plants and animals and the development and dissemination of techniques for raising them productively. Agriculture began independently in different parts of the globe, included a diverse range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin. Wild grains were collected and eaten from at least 20,000 BC. From around 9500 BC, the eight Neolithic founder crops – emmer wheat, einkorn wheat, hulled barley, lentils, bitter vetch, chick peas, flax – were cultivated in the Levant. Rye may have been cultivated earlier but this remains controversial. Rice was domesticated in China by 6200 BC with earliest known cultivation from 5700 BC, followed by mung and azuki beans. Pigs were domesticated in Mesopotamia around 11,000 BC, followed by sheep between 11,000 BC and 9000 BC. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around 8500 BC. Sugarcane and some root vegetables were domesticated in New Guinea around 7000 BC.
Sorghum was domesticated in the Sahel region of Africa by 5000 BC. In the Andes of South America, the potato was domesticated between 8000 BC and 5000 BC, along with beans, llamas and guinea pigs. Bananas were hybridized in the same period in Papua New Guinea. In Mesoamerica, wild teosinte was domesticated to maize by 4000 BC. Cotton was domesticated in Peru by 3600 BC. Camels were domesticated late around 3000 BC; the Bronze Age, from c. 3300 BC, witnessed the intensification of agriculture in civilizations such as Mesopotamian Sumer, ancient Egypt, the Indus Valley Civilisation of South Asia, ancient China, ancient Greece. During the Iron Age and era of classical antiquity, the expansion of ancient Rome, both the Republic and the Empire, throughout the ancient Mediterranean and Western Europe built upon existing systems of agriculture while establishing the manorial system that became a bedrock of medieval agriculture. In the Middle Ages, both in the Islamic world and in Europe, agriculture was transformed with improved techniques and the diffusion of crop plants, including the introduction of sugar, rice and fruit trees such as the orange to Europe by way of Al-Andalus.
After the voyages of Christopher Columbus in 1492, the Columbian exchange brought New World crops such as maize, sweet potatoes, manioc to Europe, Old World crops such as wheat, barley and turnips, livestock including horses, cattle and goats to the Americas. Irrigation, crop rotation, fertilizers were introduced soon after the Neolithic Revolution and developed much further in the past 200 years, starting with the British Agricultural Revolution. Since 1900, agriculture in the developed nations, to a lesser extent in the developing world, has seen large rises in productivity as human labour has been replaced by mechanization, assisted by synthetic fertilizers and selective breeding; the Haber-Bosch process allowed the synthesis of ammonium nitrate fertilizer on an industrial scale increasing crop yields. Modern agriculture has raised social and environmental issues including water pollution, genetically modified organisms and farm subsidies. In response, organic farming developed in the twentieth century as an alternative to the use of synthetic pesticides.
Scholars have developed a number of hypotheses to explain the historical origins of agriculture. Studies of the transition from hunter-gatherer to agricultural societies indicate an antecedent period of intensification and increasing sedentism. Current models indicate that wild stands, harvested started to be planted, but were not domesticated. Localised climate change is the favoured explanation for the origins of agriculture in the Levant; when major climate change took place after the last ice age, much of the earth became subject to long dry seasons. These conditions favoured annual plants which die off in the long dry season, leaving a dormant seed or tuber. An abundance of storable wild grains and pulses enabled hunter-gatherers in some areas to form the first settled villages at this time. Early people began altering communities of flora and fauna for their own benefit through means such as fire-stick farming and forest gardening early. Exact dates are hard to determine, as people collected and ate seeds before domesticating them, plant characteristics may have changed during this period without human selection.
An example is the semi-tough rachis and larger seeds of cereals from just after the Younger Dryas in the early Holocene in the Levant region of the Fertile Crescent. Monophyletic characteristics were attained without any human intervention, implying that apparent domestication of the cereal rachis could have occurred quite naturally. Agriculture began independently in different parts of the globe, included a diverse range of taxa. At least 11 separate regions of the Old and New World were involved as independent centers of origin; some of the earliest known domestications were of animals. Domestic pigs had multiple centres of origin in Eurasia, including Europe, East Asia and Southwest Asia, where wild boar were first domesticated about 10,500 years ago. Sheep were domesticated in Mesopotamia between 11,000 BC and 9000 BC. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around 8500 BC. Camels were domesticated late around 3000 BC, it was not until after 9500 BC that the eight so-called founder crops of agriculture appear: first emmer and einkorn wheat hulled barley, lenti
In engineering, a foundation is the element of a structure which connects it to the ground, transfers loads from the structure to the ground. Foundations are considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics in the design of foundation elements of structures. Foundations provide the structure's stability from the ground. To distribute the weight of the structure over large area so as to avoid over-loading of the soil beneath. To anchor the structures against the changing natural forces like Earthquakes, frost-heave, tornado or wind. To load the sub-stratum evenly and thus prevent unequal settlement. To provide a level surface for building operations. To take the structure deep into the ground and thus increase its stability, preventing overloading. Specially designed foundation helps in avoiding the lateral movements of the supporting material; the design and the construction of a well-performing foundation must possess some basic requirements that must not be ignored.
They are: The design and the construction of the foundation is done such that it can sustain as well as transmit the dead and the imposed loads to the soil. This transfer has to be carried out without resulting in any form of settlement that can result in any form of stability issues for the structure. Differential settlements can be avoided by having a rigid base for the foundation; these issues are more pronounced in areas. Based on the soil and area it is recommended to have a deeper foundation so that it can guard any form of damage or distress; these are caused due to the problem of shrinkage and swelling because of temperature changes. The location of the foundation chosen must be an area, not affected or influenced by future works or factors. Buildings and structures have a long history of being built with wood in contact with the ground. Post in ground construction may technically have no foundation. Timber pilings were used on soft or wet ground below stone or masonry walls. In marine construction and bridge building a crisscross of timbers or steel beams in concrete is called grillage.
The simplest foundation is the padstone, a single stone which both spreads the weight on the ground and raises the timber off the ground. Staddle stones are a specific type of padstones. Dry stone and stones laid in mortar to build foundations are common in many parts of the world. Dry laid. Sometimes the top, visible course of stone is quarried stones. Besides using mortar, stones can be put in a gabion. One disadvantage is that if using regular steel rebars, the gabion would last much less long than when using mortar. Using weathering steel rebars could reduce this disadvantage somewhat. Rubble trench foundations are a shallow trench filled with rubble or stones; these foundations extend below the frost line and may have a drain pipe which helps groundwater drain away. They are suitable for soils with a capacity of more than 10 tonnes/m2. Shallow foundations called footings, are embedded about a metre or so into soil. One common type is the spread footing which consists of strips or pads of concrete which extend below the frost line and transfer the weight from walls and columns to the soil or bedrock.
Another common type of shallow foundation is the slab-on-grade foundation where the weight of the structure is transferred to the soil through a concrete slab placed at the surface. Slab-on-grade foundations can be reinforced mat slabs, which range from 25 cm to several meters thick, depending on the size of the building, or post-tensioned slabs, which are at least 20 cm for houses, thicker for heavier structures. A deep foundation is used to transfer the load of a structure down through the upper weak layer of topsoil to the stronger layer of subsoil below. There are different types of deep footings including impact driven piles, drilled shafts, helical piles, geo-piers and earth stabilized columns; the naming conventions for different types of footings vary between different engineers. Piles were wood steel, reinforced concrete, pre-tensioned concrete. A monopile foundation is a type of deep foundation which uses a single large-diameter, structural element embedded into the earth to support all the loads of a large above-surface structure.
A large number of monopile foundations have been utilized in recent years for economically constructing fixed-bottom offshore wind farms in shallow-water subsea locations. For example, a single wind farm off the coast of England went online in 2008 with over 100 turbines, each mounted on a 4.74-meter-diameter monopile footing in ocean depths up to 16 metres of water. Foundations are designed to have an adequate load capacity depending on the type of subsoil/rock supporting the foundation by a geotechnical engineer, the footing itself may be designed structurally by a structural engineer; the primary design concerns are bearing capacity. When considering settlement, total settlement and differential settlement is considered. Differential settlement is; this can cause problems to the structure. Expansive clay soils can cause problems.
