Public Works

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. They include public buildings (municipal buildings, schools, hospitals), transport infrastructure (roads, railroads, bridges, pipelines, canals, ports, airports), public spaces (public squares, parks, beaches), public services (water supply, sewage, electrical grid, dams), and other, usually long-term, physical assets and facilities. Though often interchangeable with public infrastructure and public capital, public works does not necessarily carry an economic component, thereby being a broader term.

Public works is a multi-dimensional concept in economics and politics, touching on multiple arenas including: recreation (parks, beaches), aesthetics (trees, green space), economy (goods and people movement, energy), law (police and courts), and neighborhood (community centers, social services buildings). Essentially, it represents any constructed object that augments a nation's physical infrastructure.
