1810.4.1.5.1 Substantiation of higher allowable loads.
BC § 1810.4.1.5.1
The basic maximum allowable loads of deep foundations tabulated in Table 1810.4.1.3 may be exceeded where a higher value can be substantiated on the basis of load tests and analysis, except for the loads for timber and helical piles. The provisions of Section 1810.4.1 shall be supplemented, as follows: the final load increment shall remain in place for a total of not less than 24 hours; single tested deep foundations shall be subjected to cyclical loading in accordance with ASTM D 1143 or suitably instrumented with telltales and strain gauges so that the movements of the tip and butt of the deep foundation may be independently determined and load transfer to the soil evaluated. A complete record demonstrating satisfactory performance of the test shall be submitted to the commissioner.
