Common Work Results for Masonry Cost Estimating Tips

The terms mortar and grout are often used interchangeably and incorrectly.

Mortar is used to bed masonry units, seal the entry or air and moisture, provide architectural appearance, and allow for size variations in the units. Common mortar types are M (2500 psi), S (1800 psi), N (750 psi), and O (350 psi) and conform to ASTM C270

Grout is used primarily in reinforced masonry construction and is used to bond the masonry to the reinforcing steel. Grout is either fine or course and conforms to ASTM C476, and in place strengths generally exceed 2500 psi.

Mortar and grout are different components of masonry construction and are placed by entirely different methods. An estimator should be aware of their unique uses and costs.

Waste - Waste, specifically the loss/droppings of mortar and the breakage of brick and block, is included in RSMeans cost data for all masonry assemblies in this division. A factor of 25% is added for mortar and 3% for brick and concrete masonry units.

Scaffolding - Scaffolding or staging is not included in any of the Division 4 costs. Refer to estimaring costs for Temporary Facilities & Controls instead
