This paper discusses design features and challenges associated with the rehabilitation of Berth 24-10 at the Port of San Diego, California. The rehabilitation goals were repair of the deteriorated elements of the wharf, restoration of vertical load carrying capacity, and extension of the service life of the structure by 50 years. While a seismic retrofit was not part of the scope of this work because the original design was based on outdated seismic design principles, it was critical that rehabilitation measures did not inadvertently make the already seismically vulnerable structure worse. This paper will discuss design decisions that not only restored the berth to its original vertical load carrying capacity, but also improved seismic performance characteristics of the structure. This paper will also discuss the design decisions that made it possible to construct a new fender wale system to accommodate existing fender piles of various cutoff elevations and allow for a planned future fender pile replacement program.
