  1. Chapter 5 Measuring Concrete Work

  2. Objectives • Upon completion of this chapter, you will be able to: • Explain how concrete work, formwork, and associated items are measured in a takeoff • Explain how concrete and formwork are classified in the takeoff process • Measure concrete foundations from drawings and specifications

  3. Objectives (cont’d.) • Describe how reinforcing steel is measured • Complete a manual takeoff of concrete foundations • Complete a computer takeoff of concrete foundations using Excel spreadsheets and MC2 ICE software

  4. Measuring Concrete Work • Combination of items are measured • Shown or inferred • Concrete volume • Formwork requirements • Finishes needed • Measure all work associated with one assembly • Before moving to the next

  5. Measuring Notes—Concrete • In general: • Measure in cubic yards net in place • Don’t adjust quantity for reinforcing steel and insets • Classify concrete and measure separately • Measure mixes separately • Measurement/pricing of columns, walls, and beams dependent on placement/pouring

  6. Measuring Formwork • Formwork operations • Involve a number of activities • Allowed for in pricing of forms • Contact area is measured • Establish surfaces of concrete that require forms

  7. Measuring Notes—Formwork • Generally: • Measured in square feet of contact area • Same category classifications as concrete • Bulkheads and edge forms are measured separately • Forms to slab edges are measured separately • From forms to beams and forms to walls

  8. Measuring Notes—Formwork (cont’d.) • Openings in form systems • No deduction made from total area if size of opening is less than 100 square feet • Describe items that are linear in nature • Describe forms to circular columns • Diameter • Measure in feet to column height

  9. Measuring Notes—Finishes and Miscellaneous Work • Include: • Slab finishes • Screeds and curing slabs • Welded wire mesh • Inserts and waterstops • Expansion joints • Nonshrink grout • Saw cutting concrete • Reinforcing steel

  10. FCE Office Foundation Takeoff Using ICE Software • Sitework for the FCE Office • Takeoff of foundations • Followed by slabs • Refer to Pages 126 through 135

  22. Summary • Preparing a quantity takeoff of concrete • Requires measurement of a combination of items • Concrete: measured in cubic yards or cubic meters net in place • Formwork: measured in square feet or square meters of contact area • Concrete finishes: measured in square feet or square meters
