Concrete Estimating Guide

What Does Concrete Estimating Include?

Concrete estimating includes concrete footings, foundations, floors, sidewalks, driveways, patios, stairs, and miscellaneous concrete items.

Footing Material Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

Concrete Footing Materials Header Section

  • Use information from project plans and specifications to assist in entering the appropriate information in the blanks in the header section
  • Some information was already determined when you did your basic takeoffs.  Write a formula that will automatically place the information in the correct cell when it is entered on the basic take-off sheet.

Footing Material

  • Footing concrete quantity should be automatically calculated using the information from the header section. The amount of concrete needed should be calculated to the nearest ¼ of a yard including a waste factor.
  • The quantity of footing forms should be automatically calculated from the information given in the header section and should include the waste factor (Use Random Length Form Material).
  • The quantity of horizontal rebar should be automatically calculated from the information given in the header section and should include the waste factor.
  • The number of footing dowels should be automatically calculated from the information in the header section.
  • Stakes, spreaders, bracing should be automatically calculated from information given in the header section.
  • Tie wire and form oil should allow for manual input of material quantities

See Concrete Footings in the Reference Book for an explanation of the various costs associated with this item.

Footing Labor Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

  • Use the cost for “Board Forming and Stripping” from the Residential Section of the NCE for determining forming cost.
  • Use the cost for “Concrete Reinforcing Steel” from the Residential Section of the NCE to determining reinforcing costs
  • Use the cost for “Column Footings” from the Residential Section of the NCE to determine the concrete placing cost.

Foundation Material Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

  • The Foundation Concrete row should allow you to select a type of concrete from a data validation list and automatically fill in the size, units, and unit cost columns.  The quantity of concrete should be determined by summing up the total cubic yards of concrete including a waste factor and rounded to the nearest ¼ yard.
    The foundation reinforcing quantity should be determined by automatically calculating it from the information in the header section.
  • The foundation form material cost should be determined by using the “Plywood Forming” Material cost from the Residential Section of the NCE. Assume that the forms will be used 5 times
  • The labor cost for the foundation earthquake straps should be determined by using the “Hold Downs (HD) subsection of the “Framing Connectors” subsection of the Residential section of the NCE. Use the HD10A option.

See Concrete Foundations in the Reference Book for an explanation of the various costs associated with this item.

Foundation Labor Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

  • Use the “Plywood Forming” cost from the Residential Section of the NCE for determining the foundation forming cost.
  • Use the “Concrete Reinforcing Steel” cost from the Residential Section of the NCE. For determining the cost for installing the reinforcing steel in the foundation.
  • Use the “Concrete Walls” section from the Residential Section of the NCE for determining the concrete placement costs.
  • Use the “8” thick walls, 4’ to 8’ high pumped option”.
  • Use the Residential Section of the NCE for determining the anchor bolt placement cost.
  • Damproofing should be installed below grade on the foundation that encloses the living area. Use the Dampproofing, asphalt emulsion, Brush On” in the Thermal and Moisture Protection Section of the Commercial Section of the NCE.
  • Pargeting is done on all foundation areas that are above grade and exposed to view. Use the “Pargeting, 2 coats, ½” thick” option in the Masonry Section of the Commercial Section of the NCE. For determining the pargeting cost.

Concrete Floor Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

Concrete floor quantities can be manually calculated and input or you may choose to automate the subsections.

See Concrete Floors in the Reference Book for an explanation of the various costs associated with this item.

Concrete Floor Labor Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

Use the “Slab, Walks, and Driveways subsection of the Residential Section of the NCE for determining concrete floor labor.

Sidewalk and Driveway Material Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

Concrete sidewalk and driveway quantities can be manually calculated and input or you may choose to automate the subsections.

Sidewalk and Driveway Labor Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

Use the “Slab, Walks, and Driveways subsection of the Residential Section of the NCE for determining concrete floor labor.

Concrete Steps Material Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

Concrete steps can be manually calculated and input or you may choose to automate the subsections.

To form the front porch, you will need enough 2”x8” material to form around the porch edge and the entry step.

Concrete Steps Labor Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

Use the prices “Steps on grade” from the Residential Section of the NCE.

Foundation Finish Estimate

Line items in this section of the Worksheet:

Estimating Process

Ensure the materials databases are updated and correct. Then select the number of window wells needed.

Foundation Finish Labor Cost Estimate

Line items in this section of the Worksheet:

Estimating Process

Use “Window Wells” from the Residential Section for finding the installation cost of window wells. Use the 4048-54 Option.
