ABSTRACT : The presentation will update progress of the installation of drilled shaft elements comprising the two main pylon and multiple approach foundations for the Houston Ship Channel Bridge (HSCB), whose construction began in January of 2018. Several installation issues encountered during construction of the drilled shafts will be presented, along with a discussion of the results and benefits derived from undertaking cross-hole sonic integrity (CSL) testing of each of the nearly 100, 8-foot-diameter and 225-foot deep drilled shafts. The presentation will close with a brief history of major geotechnical issues considered during design of the HSCB.
