This project involved the rehabilitation/repairs to the existing Barge Slip Ramp at Kwajalein Island. Work included installation of 295 LF of PZ-27 coal tar epoxy-polyamide coated hot rolled/joint interlocked steel sheet piles. Piles are 38.5 feet long and driven to 26 feet below existing mud line. Face of new piles is 3’ seaward of the existing sheet pile bulkhead with the interstitial space filled with 5,000 psi marine concrete. Thirteen (13) 1.375” diameter steel tie rods connect to new 8’x4’x9” reinforced concrete dead men. New steel walkers were tied into a cast-in-place epoxy coated steel reinforced concrete slab. Twenty-one (21) new molded rubber fenders, five (5) 24” diameter pipe bollards and 4-15 ton cast steel mooring cleats also were installed. Demolition included removal of existing cylindrical fender system, portions of the existing bollards, and portions of the existing concrete slab.
