Private construction is typically categorized into residential (for example, home improvements and single-family buildings) and non-residential (e.g. power facilities, commercial, manufacturing, health care and education) construction projects. The value of new residential buildings put in place by privately owned construction companies in 2019 was around 515 billion U.S. dollars while that of non-residential buildings stood at over 463 billion U.S. dollars in that same year. Most new private sector non-residential construction projects are carried out in the Southern parts of the United State, with Texas being one of the highest contributing states. Buildings for farms, warehouses, multi-retail outlets and the automotive industry constitute standard examples of private sector commercial construction. In manufacturing, the chemical industry has tended to dominate in the value derived from manufacturing construction that emanates from the private sector.
Bechtel, one of the leading privately owned American corporations, is one of the largest companies—either public or privately owned—in the United States that deals with civil engineering projects and construction. Some of the other leading private construction companies in the United States include: the Koch Industries, Kiewit Corporation, the Renco Group as well as, the Clark Enterprises.
