Which term describes a concrete element cast and cured away from the construction site?

• A. Prestressed Girder
• B. Precast
• C. Preliminary Design
• D. Profile

Answer: (B)

Off-site fabrication is the idea here: a concrete element that is cast and cured away from the actual construction site in a controlled plant, then transported to the site and installed. This is what precast concrete refers to. Casting in a factory allows better quality control, faster on-site erection, protection from weather, and the ability to produce standardized or complex shapes like beams, columns, and panels before they ever arrive at the structure. In contrast, a prestressed girder is about applying internal prestressing to a member (which can be precast or cast in place), preliminary design refers to early-stage planning, and profile describes the shape or cross-section rather than where the concrete is cast.
