Estimating Ceiling Heights

Ceiling Heights

The BidMagic construction estimating software includes a field for the ceiling height on each story of your construction project.

Enter the average ceiling height for each story that is part of the project. For new construction, include the entire building. For an addition, include the addition only. For a gut/ rehab project, include those portions of the building that are being gutted and rehabilitated.

If the entire story has the same ceiling height, use that measurement.

If only a small part of the project has a lower ceiling height (for example, just hallways and bathrooms) ignore the height reduction, and use the ceiling height found in most of the project.

If ceiling heights vary between different parts of the project, use a weighted average (see page 377).

Areas under cathedral ceilings--where the upper floor has been removed to produce an area two stories high--should be treated as having a normal ceiling height on each story. Don't enter such areas as double-height, since the 'excess' wall area will be figured in when you enter walls in the upper story (see pages 372-374).

NOTE: For more about high ceilings, see page 374. For sloped ceilings, see pages 374-375.
