Parts of the building are built in a different location and then shipped to the construction site. Prevalent in highway bridge construction; tilt-slab construction. Which construction method is this?

• A. Cast in Place
• B. Spalling
• C. Pre-Cast
• D. Type I - Fire Resistive

Answer: (C)

Off-site fabrication and assembly of concrete components is precast construction. In this approach, parts of the building—such as wall panels, beams, or bridge segments—are cast and cured in a controlled factory, then transported to the site and erected. This method is especially common in highway bridge work and in tilt-up (tilt-slab) construction, where wall panels are made elsewhere, transported, and lifted into place. Cast-in-place would involve pouring concrete on the job site rather than shipping finished pieces. Spalling is a concrete damage phenomenon, not a construction method, and Type I - Fire Resistive is a fire-resistance rating category, not about how components are manufactured or assembled.
