In tilt-up planning, which statement best describes the order of erection based on height?

• A. Height is not considered
• B. The shortest panel goes first
• C. Random order
• D. The tallest panel goes first

Answer: (D)

In tilt-up planning, the order of erection is guided by height to optimize crane access, alignment, and stability as the wall goes up. Erecting the tallest panel first establishes the primary vertical element of the structure early, giving a clear reference for all subsequent lifts. This approach helps manage the crane’s reach and movements, minimizes the risk of taller pieces having to maneuver past already-placed panels, and sets up a stable frame that the shorter panels can later tie into. Once the tall panel is in place and braced, you can bring in the remaining panels and connect them to the established vertical framework, finishing the walls in a logical, controlled progression. Starting with the shortest or random order can complicate crane setup, increase risk of interference, and make bracing and alignment more difficult as the project progresses, which is why placing the tallest panel first is the best approach.
