Public works (or internal improvements historically in the United States) are a broad category of infrastructure projects, financed and constructed by the government, for recreational, employment, and health and safety uses in the greater community.
In the 18th century, the construction organisation was a part of the Army as the Public Works Department (PWD) manned by the Indian Corps of Engineers was created under the control of a Military Board. By 1851, the PWD came under the civil control but was responsible for both civil and military works.
