Public works

Public works are a broad category of infrastructure projects, financed and procured by a government body for recreational, employment, and health and safety uses in the greater community. They include public buildings (municipal buildings, schools, and hospitals), transport infrastructure (roads, railroads, bridges, pipelines, canals, ports, and airports), public spaces (public squares, parks, and beaches), public services (water supply and treatment, sewage treatment, electrical grid, and 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. Construction may be undertaken either by directly employed labour or by a private operator. Public works has been encouraged since antiquity. For example, the Roman emperor Nero encouraged the construction of various infrastructure projects during widespread deflation. Public works is a multi-dimensional concept in economics and politics, touching on multiple arenas including: recreation (parks, beaches, trails), aesthetics (trees, green space), economy (goods and people movement, energy), law (police and courts), and neighborhood (community centers, social services buildings). It represents any constructed object that augments a nation's physical infrastructure. Municipal infrastructure, urban infrastructure, and rural development usually represent the same concept but imply either large cities or developing nations' concerns respectively. The terms public infrastructure or critical infrastructure are at times used interchangeably. However, critical infrastructure includes public works (dams, waste water systems, bridges, etc.) as well as facilities like hospitals, banks, and telecommunications systems and views them from a national security viewpoint and the impact on the community that the loss of such facilities would entail. Furthermore, the term public works has recently been expanded to include digital public infrastructure projects.
