For the subcontractor quantity check at the bank drive-through canopy, the #6 grade-beam bars takeoff has 87 bars at 24 ft each. Using 1.502 lb per ft for beam reinforcement, what reinforcing weight is estimated?
Correct Answer
C) 3,136 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: 2,088 lb
2,088 lb is below the supported result for #6 grade-beam bars; it likely uses the wrong base, period, or account bucket.
Option B: 131 lb
131 lb is below the supported result for #6 grade-beam bars; it likely uses the wrong base, period, or account bucket.
Option D: 3,512 lb
3,512 lb is above the supported result for #6 grade-beam bars; it likely adds an unsupported amount or compares the wrong financial base.
