Measuring Concrete Work Chapter 5 Measuring Concrete Work
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
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
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
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
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
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
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
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

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
