Construction is the process of constructing a building or infrastructure. Construction differs from manufacturing in that manufacturing typically involves mass production of similar items without a designated purchaser, while construction typically takes place on location for a known client. Construction as an industry comprises six to nine percent of the gross domestic product of developed countries. Construction starts with planning, design, and financing; it continues until the project is built and ready for use.
Construction is a general term meaning the art and science to form objects, systems, or organizations, and comes from Latin constructionem (from com- “together” and struere “to pile up”) and Old French construction.Construction is used as a verb: the act of building, and a noun: how a building was built, the nature of its structure.
