Which type of structure is partially or completely built in a factory and shipped to the installation location?

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

Answer: (D)

Prefabrication and off-site construction involve making a structure in a factory and shipping it to the installation site. Factory-built homes are produced in a controlled factory environment, delivered as modules or sections, and then assembled on a foundation at the destination. This contrasts with components built entirely or mostly on site, like a bowstring truss or cast-in-place concrete, and with doors such as fire doors that are installed within a structure rather than forming the whole building. So the structure that is partially or completely built in a factory and shipped to the site fits the factory-built home.
