During the buyout verification pass at the middle-school kitchen line, the #6 grade-beam bars takeoff has 150 bars at 36 ft each. Using 1.502 lb per ft for beam reinforcement, what reinforcing weight is estimated?
Correct Answer
C) 8,111 lb
Reinforcing weight equals bar count times length times pounds per foot.
Why This Is the Correct Answer
Reinforcing weight equals bar count times length times pounds per foot.
Why the Other Options Are Wrong
Option A: 5,400 lb
5,400 lb is below the supported result for #6 grade-beam bars; it likely omits allowance, conversion, coverage, or final round-up.
Option B: 225 lb
225 lb is below the supported result for #6 grade-beam bars; it likely omits allowance, conversion, coverage, or final round-up.
Option D: 9,084 lb
9,084 lb is above the supported result for #6 grade-beam bars; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Memory Technique
Concrete Estimator takeoff: count the condition before counting the package.
