Project won ASCE Construction Achievement Project of the Year Award. Provided construction inspection for installation of a floating fendering system designed to protect the FDR Drive from errant vessels on the East River. A temporary Outboard Detour Roadway was constructed on the East River adjacent to the FDR Drive to replicate the closed FDR travel lanes. The 3,000-foot-long fender system consisted of fifty-two 24-inch diameter grout tension anchors drilled to depths of 190-feet, 13 floating steel dolphins held by 7-inch diameter anchor chains, and 10-foot diameter steel floating breasting beams. The grout anchors were load tested to 330 tons in tension. (Design-build, Designers: Daniel Frankfort, TAMS, DMJM+Harris, Contractor: Slattery)
