During the subcontractor quantity check at the maintenance-shop wash bay, the #4 slab dowels takeoff has 27 bars at 34 ft each. Using 0.668 lb per ft for dowel stock, what reinforcing weight is estimated?
Correct Answer
A) 613 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 B: 918 lb
918 lb is above the supported result for #4 slab dowels; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option C: 18 lb
18 lb is below the supported result for #4 slab dowels; it likely omits allowance, conversion, coverage, or final round-up.
Option D: 687 lb
687 lb is above the supported result for #4 slab dowels; it likely double-counts allowance, uses the wrong unit, or rounds too early.
