Common Pitfalls in Bi-Directional Static Load Testing
The bi-directional static load test (BDSLT) has become a widely accepted and popular test method for deep foundation elements, such as drilled shafts, ACIP piles, and barrettes. The assembly, installation, and testing of BDSLT foundation elements and interpretation of the resulting data are both an art and a science. Irretrievably installing a hydraulic loading apparatus and instrumentation deep into concrete in a manner that ensures that everything will work correctly takes planning and experience. Once successfully installed, the inverted nature of the test itself requires that the data be properly interpreted in order to be useful for the client, engineer, and ultimately the owner. This paper discusses some of the issues which can arise during the assembly, testing, and interpretation of BDSLTs to the detriment of the project. The various observations have been collected from the author’s extensive experience in the BDSLT field as well as published results in the literature.
