Cast in place concrete refers to concrete cast where?

• A. Concrete poured off-site
• B. Concrete cast off-site and cured elsewhere
• C. Concrete molded in a factory and delivered
• D. Concrete cast on-site

Answer: (D)

Cast in place means the concrete is poured into forms and cured at the actual project site, with formwork built on site and the final piece standing in its intended location. This distinguishes it from precast methods, where concrete is cast in a factory, cured there, and then delivered to the site. So the method is on-site because the work happens where the building stands, not off-site. The other options describe off-site pouring or factory casting and delivery, which are precast or off-site processes.
