Estimating Inside Walls

Estimating Inside Walls

Enter the total length of any walls that are completely enclosed by the project and being worked on, for each story of the project.

HINT: The BidMagic estimating software does not suggest a quantity for interior walls in any type of construction project, since they vary so much between projects.

For new construction, enter the total length of all interior walls.

For an addition, enter the total length of all new interior walls in the addition. At the contact wall between the addition and the old building, include only the length (if any) that is getting completely new framing with new surfaces on both sides.

NOTE: If you are doing a small quantity of new framing in the existing building, include the length of new walls there, as well.

For a gut/rehab project, include the total length of all interior walls that will be worked on--whether they are getting new framing, new wallboard or new trim.

When measuring the length of inside walls, measure right through doors, but skip any openings that will not be filled with a door. Include the length of all interior walls that show up on the plans, even if they are not full height (see page 371).

Exclude porches, decks and sheds. Exclude party walls (walls on the exterior that aren't exposed to the outdoors).

Exclude the garage, unless it is included as part of the main building.
