Pier foundation is a grid system of girders (beams), piers, and footings used in construction to elevate the superstructure above the ground plane or grade. The piers serve as columns for the superstructure.
Note: Use the Hillside Foundation option if the residence is suspended over a hillside.
When entering this foundation type you must enter the following:
- Foundation Material – the percentage of each foundation material type (concrete, block, brick, fieldstone, treated wood, or steel), with a total percentage of 100%.
Enter a percentage between 0 and 100.
