Which construction method involves pouring concrete into forms and letting it take the shape of the form where it will be used?

• A. Cast-in-place Concrete
• B. Factory-Built Home
• C. Fire Stop
• D. Fire Door

Answer: (A)

Pouring concrete into forms on the job site and letting it cure to take the exact shape defined by those forms is poured-in-place concrete. This method uses formwork to shape walls, slabs, or foundations, with reinforcement placed inside before the concrete is poured, so the final structure becomes a single, integrated element in its destined location. It’s described by the idea that the concrete takes the shape of the form where it will be used, since the pour occurs in place rather than being cast elsewhere and transported.

This differs from precast methods, where concrete is cast in a factory, cured, and then transported to the site as finished components. The other options relate to fire safety features or different building approaches (such as modular construction) rather than the on-site forming and pouring process.
