Define 'panelizing' the building.

• A. Designing the building's foundation
• B. Choosing exterior finishes
• C. Calculating crane load for erection
• D. Determining how many walls are divided into panels (shapes & joints)

Answer: (D)

Panelizing in tilt-up construction means planning how a building’s walls are broken into individual wall panels, with defined shapes and joints. This involves deciding how many panels each wall will be divided into and where the panel boundaries, joints, and openings will be. This layout governs how each panel is cast, where lifting inserts and reinforcement go, and the sequence of erection, since smaller, well-defined panels are easier to lift and place. The key idea is that panelizing focuses on dividing walls into panels and detailing their boundaries, shapes, and joints. It isn’t about the foundation, exterior finishes, or crane load calculations themselves, which are separate considerations—panelizing is about the panel boundaries and how walls are segmented.
