Method Summary

Column load testing should be performed prior to production column construction to verify column capacity and settlement. The tests also ensure that the proposed column construction procedures will result in the desired performance. Load tests should be conducted in general accordance with ASTM D-1143, Standard Test Methods for Deep Foundations Under Static Axial Compressive Load. The exact test specifications will vary based on the column type used. Load tests should be performed after excess pore pressures induced during construction have dissipated and enough time has elapsed for the concrete or gout to cure (if applicable).
