Structural

Foundation

In Plain English

The part of a building below grade that transfers all weight to the ground.

Definition

The lowest structural element of a building that transfers all loads from the structure to the supporting soil or rock. Foundations are classified as shallow (spread footings, mat foundations) or deep (piles, drilled piers) depending on the soil conditions and load requirements. A properly designed foundation prevents settlement, movement, and structural failure.

Example

The geotechnical report recommended a mat foundation to distribute the high column loads across the entire building footprint.
