SJ Hamill has performed a test pile program where a select amount of piles were driven from a barge in the Cooper River inside the footprint of the Port’s future wharf structure. The test piles consisted of 24″ and 30″ pre-stressed square concrete piles ranging in length from 69-feet to 81-feet, each cast with a 40-foot H-pile stinger. The work included building and removing template frames, axial load testing on each pile, restriking piles, static lateral load testing on half of the piles after installation, removal, and replacement of armor stone at each pile location, along with video recording/documentation of the entire operation. SJ Hamill worked together with the SCSPA managers and engineers to collect the results of the pile installation and load tests needed to evaluate drivability and to refine the design of the future wharf structure piles.
