Abstract

An evaluation of the capacity of piles supporting an existing five-story building became necessary when heavy new shear walls were proposed for the structure. Data regarding these piles was obtained from the soil investigation report for the project, from two pile load tests at the site, and from driving records for 229 production piles. Additional information was derived from soil borings and pile load tests for two adjacent buildings. Calculations were made of the anticipated pile capacities of piles at load test locations, and empirical correction factors developed to modify the calculated values to match the load test results. The same calculation methods and empirical correction factors were then used to develop ultimate capacities at each production pile location, and appropriate safety factors applied to estimate allowable pile capacities.

Existing Pile Load Capacity Evaluation
