Where load tests are required, at least two load tests shall be performed for a site having a footprint between 5,000 square feet (464.5 m 2 ) and 30,000 square feet (2787.1 m 2 ), and one additional load test shall be performed for each 20,000 square feet (1868.1 m 2 ) of added footprint area. For conditions where multiple deep foundation types or capacities are used, refer to Section 1810.2.5.
