While preparing the look-ahead planning meeting for the pharmacy tenant improvement, the interior pit perimeter requires 168 LF of pit-wall forms at 3.5 ft high on 2 sides. What contact area is required?
Correct Answer
C) 1,176 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: 588 SF
588 SF is below the supported result for pit-wall forms; it likely omits allowance, conversion, coverage, or final round-up.
Option B: 336 SF
336 SF is below the supported result for pit-wall forms; it likely omits allowance, conversion, coverage, or final round-up.
Option D: 1,470 SF
1,470 SF is above the supported result for pit-wall forms; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Memory Technique
Measure to form, adjust for contact, then let Concrete Foreman set the finish line.
