Review Questions

1. What factors affect the costs of labor when estimating
   masonry?


2. How may the type of bond (pattern) affect the amount
   of materials required?
   3. Why is high accuracy required with an item such as
   masonry?
   4. Why should local suppliers be contacted early in the bid-
   ding process when special shapes or colors are required?
   5. Why must the estimator separate the various sizes of
   masonry units in the estimate?
   6. What is a cash allowance and how does it work?
   7. How are stone veneer quantities estimated?
   8. How may cold weather affect the cost of a building?
   9. Determine the masonry, mortar, accessories, and any other
   related items required for the building in Appendix B.


3. Assume that the building in Appendix C has all exterior
   walls of 4-inch brick with 8-inch concrete block backup.
   Estimate the masonry, mortar, and accessories required.
   Note: Brick begins at elevation 104¿4.


4. Using Billy’s Convenience Store found in Appendix F, esti-
   mate the quantity of brick veneer and split-faced block.
