What is the total linear feet of rebar required for the grade beam at the west wall of the master suite?

• A. 40 Feet
• B. 43 Feet 8 Inches
• C. 46 Feet
• D. 50 Feet

Answer: (B)

The amount of rebar for a grade beam is determined by the physical length of the beam it reinforces, including any required laps or splice lengths specified in the plan. For the grade beam along the west wall of the master suite, the beam runs the full length of that wall, which is 43 feet 8 inches. So the total linear footage of rebar needed along that beam is 43 ft 8 in. The other figures would imply shorter or longer beam lengths than the plan shows, which is why they don’t fit. In short, use the wall length from the plan, 43 ft 8 in, as the total rebar length for that grade beam.
