    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
