Masonry takeoffs should be built by wall type rather than one blended square-foot number. CMU, brick veneer, architectural block, and other masonry assemblies have different materials, reinforcement, accessories, and labor.
Measure walls by assembly
Use plans, elevations, wall sections, and schedules to identify each masonry type. Measure gross wall area, then account for openings according to the estimating method being used. Track wall height and thickness because both affect production and material.
Build the material scope
Depending on the assembly, carry masonry units, mortar, grout, reinforcing steel, joint reinforcement, anchors, ties, flashing, weeps, control-joint materials, lintels, bond beams, and accessories shown in the documents.
Openings need more than a deduction
Doors, windows, louvers, and large penetrations may reduce unit quantity but add jamb work, lintels, reinforcing, flashing, and layout labor. Treat the opening as a condition, not simply negative square footage.
Separate structural and veneer conditions
Structural CMU and masonry veneer should not share one production assumption. Reinforcement, grout lifts, scaffolding, access, cleaning, and weather protection can materially change the estimate.
State the boundary
Clarify whether excavation, foundations, structural steel lintels, insulation, air barriers, sealants, and final cleaning belong to the masonry scope. A clear boundary prevents duplicate or missing costs.
