Hillside

foundation hillside

Residential construction that is suspended over sloped terrain or hillsides. A hillside foundation is typically made of materials such as wood or steel columns that are set on concrete caissons (or footings), allowing part or all the residence to be suspended out over sloped terrain.

As a "total component" valuation software, RCT does not assume an overall adjustment factor for valuing this type of foundation and the related costs associated with hillside construction. Instead, it uses appropriate construction components to provide the estimated cost of hillside construction.

Note: Do not use this option for ordinary foundations or basements where foundation excavation is merely dug into the side of a hill and the foundation is built as though on a flat surface.

When you enter this foundation type you must enter the following:

Enter only the percentage, between 0 and 100, of the home that is suspended over a sloped terrain.

In addition to entering the hillside percentage, you must also enter the approximate degree of steepness of the terrain covered by the suspended portion of the home using the Hillside Slope field under Basement Information.
