  1. Con 4003cve 4073-5073 Construction Cost Estimating Class #7 - Masonry Prof. Ralph V. Locurcio, PE

  2. Overview • About Masonry Construction • Masonry Walls • CMU Block • Reinforcing bars • Structural Brick • Brick Veneer • Mortar • Example

  3. Masonry Walls

  4. What is Masonry Construction? Bricks and CMU blocks Available in many sizes, grades, and textures Plans and Specs will determine size, color, etc. Specs will also determine the joint and type of mortar to use

  5. CMU Block • Many different types • The components block • Block or brick • Reinforcement • Mortar • Grout • Imbeds • Anchor bolts

  6. Reinforcing Bars • Bars run in horizontal & vertical directions • Typical spacing 32” OC • Additional bars added around openings

  7. Reinforcing Bars cont'

  8. Bond Beam • Adds strength to CMU or Brick wall • U-shaped CMU block filled with cement • Rebars provide lateral strength • Forms a horizontal “beam”

  9. Example 6.1

  10. Draw a picture of the problem 2 feet 4 feet 10 feet 4 feet 32” 100 feet

  11. Example 6.1 = 8” = 16” 1136 blocks 225 blocks

  12. Example 6.1

  13. Example 6.1

  14. Example 6.2

  15. Example 6.1 Bond Lintel Bullnoze

  16. Example 6.1 2”x 8” Bracing

  17. Specialty Blocks

  18. Brick walls

  19. Structural Brick

  20. Brick Veneer • The brick veneer must bear on a footing, foundation, wall or steel ledger, and this is created by bolting a steel angle iron to the wall. • A typical steel lintel is 4” • Package includes: • Brick • Weather Barrier • Lintels • Mortar • Ties

  21. Veneer Brick Wall

  22. Mortar What is Mortar??

  23. Mortar • Mixture of cement, sand & lime • Binds the blocks/bricks together • Seals against the elements • Lime adds workability, elasticity, water retention • Sand acts as a filler and aggregate • Mortar is often colored

  24. Example 6-3

  25. Example 6-3

  26. Example 6-3

  27. Exsample 6-3

  28. Conclusion • Masonry consists of: • Block • Structural Brick • Brick Veneer • Work package for block and structural brick • Block or brick • Reinforcement • Mortar • Grout • Imbeds • Anchor bolts

  29. Conclusion-2 • The work package for Brick Veneer includes: • Brick • Weather Barrier • Lintels • Mortar • Ties

  30. HW #3 - Masonry • Chapter 6…. handout • Problems 6-7, 8, 9, 10 • Problem 6-13 • Problems with HW #2 • Calculations missing/incomplete • Difficult to understand • Materials missing • Incorrect costs • Didn’t use estimating template • Some gave too much credit
