Step 1

Read the flooring product specifications to determine the thickness of the architectural flooring material--including any padding or other substrate that lies beneath the architectural flooring material--and the adhesive, if any, used to adhere the flooring material to the structural floor of the building.

Step 2

Add the thickness of the flooring material to the thickness of any padding or other substrate.

Step 3

Locate the structural floor height specified in the flooring project plans. Add the combined height of the architectural floor material, substrates and adhesives to the structural floor height. This is the finished floor level.

Elevation problems

Using the highest point on the foundation as a reference, Jason found two areas with notable variation: the west side of the Bedroom 3 foundation was 1/2 inch low, and the south side of the three-season room foundation was 3/4 inch low.
