Topic: HUGH K. LEATHERMAN TERMINAL BUILDINGS & CANOPIES VALUE ENGINEERED FOUNDATIONS, North Charleston, South Carolina
The South Carolina Ports Authority (SCPA) is currently building the Hugh K. Leatherman Terminal (HLT). The terminal is built on historic marsh, dredge spoils, even an abandoned Navy airfield runway, where post-construction settlement is anticipated up to 12 inches (305 mm) over 25 years. The settlement will impart downdrag forces on the driven piles supporting the building and canopy structures planned at the site. Further review indicated that a primary reason for the long piles planned was downdrag loading, which was calculated using traditional methods. In order to minimize cost and constructability considerations of the long piles, Insight Group in coordination with SCPA recommended an alternate design approach, referred to as 'Neutal Plane Method'. High strain dynamic test results in conjunction with Neutral Plane analyses findings were used to develop production pile driving criterion for each structure. As a result, production pile length reductions ranging from 6 feet (1.8 meters) to 27 feet (8.2 meters) were achieved on the project. PDA testing and Neutral Plane analyses results for one representative building are presented and the benefits of shorter piles in terms of constructability and overall project cost-savings are discussed.
