List the items that would be included on a pre-pour checklist for panels?

• A. Elevator location
• B. Temperature, formwork, panelization, sequencing and layout, rebar, design, bondbreaker
• C. Paint colors
• D. Roof materials

Answer: (B)

When planning a tilt-up panel pour, the key is to verify every factor that directly affects the panel’s shape, strength, and restraint before concrete goes in. The items on a pre-pour checklist for panels cover crucial aspects that ensure the panels will pour correctly and perform as designed.

Temperature matters because concrete temperature influences setting rate, workability, and cure, affecting strength and cracking potential. Formwork is checked to ensure the molds are correctly built, braced, and sealed so the panel takes its intended shape and dimensions without leaks or deformation. Panelization and sequencing and layout focus on how panels are grouped, where each one sits relative to others, and the order in which pours occur so alignment, gaps, and joint locations line up with the design. Rebar placement is inspected to confirm the reinforcement is in the right location, properly sized, spaced, and spanned as required, with all ties, couplers, and embeds in place. Design compatibility is reviewed to ensure the pour follows the engineered drawings, including thicknesses, openings, embedments, and any special features. Bondbreaker is used where needed to prevent unwanted adhesion between the panel and the bed or adjacent components, allowing proper separation and joint movement after curing.

Other items like elevator location, paint colors, or roof materials don’t directly affect the pour itself, so they aren’t part of the essential pre-pour checklist for panels.
