This is needed to determine both the lengths of the rebar and how many rows and columns are needed. Subtract the clearance from the length and width to find the dimensions of the grid. For example, if the slab is 10′ x 10′ and the clearance is 3″, the size of the rebar grid will be 9′ 6″ x 9′ 6″. Step Three: Estimate the Rows and

get priceAn ordinary person can estimate reinforcement as a lump sum. I see many people estimate reinforcement as a percentage of concrete volume. Such as 2% or 1.5% of concrete volume. But as a construction professional you shouldn’t estimate rebar quantity as a percent of concrete volume. You should estimate that as shown in the structural drawing.
