Determining a Unit Price for Masonry

Now, to calculate the concrete block (Concrete Masonry Unit or CMUs), there are 1.125 CMU per square foot of wall (without extras). Doing the math, 400 square feet times 1.125 CMU per square foot equals 450 CMU. The materials you install will be mostly on grade, but you will have to construct a hop board or a small scaffold to top out the coursing. Get price
