Public works
Public works are a broad category of infrastructure projects, financed and procured by a government body for employment, health and safety, and recreational uses in the greater community. They include environmental protection (drinking water protection, preservation and restoration of forests and wetlands, soil erosion reduction, wildlife habitat preservation), public buildings (hospitals, municipal buildings, and schools), public services (dams, electrical grid, sewage treatment, and water supply and treatment), public spaces (beaches, parks, and public squares), transport infrastructure (airports, bridges, canals, pipelines, ports, railroads, and roads) and other, usually long-term, physical assets and facilities.
