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

FCE Office Foundation Takeoff Using ICE Software• Sitework for the FCE Office

– Takeoff of foundations• Followed by slabs

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
