Building information modeling (BIM) is a process involving the generation and management of digital representations of the physical and functional characteristics of buildings and other physical assets. BIM is supported by various tools, technologies and contracts. Building information models (BIMs) are computer files which can be extracted, exchanged or networked to support decision-making regarding a built asset. BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain buildings and diverse physical infrastructures, such as water, refuse, electricity, gas, communication utilities, roads, railways, bridges, ports and tunnels.

Construction is a general term meaning the art and science of forming objects, systems, or organizations. It comes from the Latin word constructio and Old French construction. To 'construct' is a verb: the act of building, and the noun is construction: how something is built or the nature of its structure.
