During the look-ahead planning meeting at the laboratory exhaust chase, the slab edge requires 408 LF of thickened-edge forms at 3.5 ft high on 1 side. What contact area is required?
Correct Answer
B) 1,428 SF
Form contact area equals length times height times the number of formed sides.
Why This Is the Correct Answer
Form contact area equals length times height times the number of formed sides.
Why the Other Options Are Wrong
Option A: 408 SF
408 SF is below the supported result for thickened-edge forms; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 1,785 SF
1,785 SF is above the supported result for thickened-edge forms; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 1,429 SF
1,429 SF is above the supported result for thickened-edge forms; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Memory Technique
Thickened-Edge cart for Concrete Foreman: form first, contact second, whole sf last.
Reference Hint
Open-book path: tab Principles and Practices of Commercial Construction, 10th Edition to Concrete slab forming; edge form area; verify the construction method, material quantity, equipment use, unit conversion, or field-control calculation.
