OSB Subflooring Framing Cost
Construction ITEM DESCRIPTION
Construction estimating unit cost for installation of oriented strand (OSB) subflooring. This is a 'one size fits all' assembly which calculates the cost for any thickness of subfloor.
NOTE-- for 3/4" OSB subflooring, click here.
One square foot of subflooring area.
We figure about 77 square feet of subfloor installer per hour of carpenter time, with a little help from an unskilled laborer.
NOTE-- We do not use a labor modifier, so the same labor cost will apply to any thickness of subfloor. The installation time is probably going to be the same for any thickness, but there may be slightly more labor time to lug around thicker sheets of plywood. If you are concerned about that cost (probably about 1 cent per square foot), enter a labor multiplier, and apply it only to the unskilled labor component in this assembly.
One sheet covers 32 square feet, with a 10% waste factor. The cost also includes some fasteners.
Goldenseal uses the price for 3/4" (19 mm) OSB board, and then adjusts it for other subfloor thicknesses from the Structural Dimensions screen for the project.
Upstairs framing area (first floor and upper floors combined).
