Structure partially built in a factory and shipped to the installation site?

• A. Bowstring Truss
• B. Cast-in-place Concrete
• C. Eave
• D. Factory-Built Home

Answer: (D)

Off-site construction involves making major building parts in a factory and delivering them to the site for assembly. A factory-built home is designed to be manufactured in a factory, with walls, roof sections, and sometimes whole modules completed there, then shipped and installed at the site. This directly matches the idea of a structure being partially built in a factory and then moved to the installation location.

Cast-in-place concrete is poured on site, not shipped as components. An eave is simply part of the roof edge, not a structure built off-site. A bowstring truss is a type of roof framing that can be prefabricated, but it describes a component rather than the whole building approach.
