Precast concrete was invented in 1905, in Liverpool, England and has become commonplace in the modern world. The process begins with creating molds that concrete is poured into to form components of a larger construction build. These "precast" pieces are typically created offsite, away from the construction site, and in temperature controlled factories. This allows the construction team to ensure the concrete structures are cured perfectly. Once the components are approved, they are transported to the construction site and put into place.
