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 2015 was around 417 billion U.S. dollars while that of non-residential buildings stood at over 380 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.
