THE PRECAST PIER

The article describes how engineers tackled the problem of constructibillity, value engineering, and redesinging a Navy berthing pier, and so reduced construction time and cut costs while advancing the design technology of marine structures. The pier was designed to rest on 752 concrete piles, 24 inches square and 36 inches cylindrical, with batters both parallel and transverse to the pier; the deck was partially precast. The contractor offered a comprehensive value engineering change proposal based on increased precasting and use of an enormous 340 ton floating crane. A 54-inch concrete pile was decided on. Fewer piles would be needed and the difficulty of driving solid concrete piles and battered piles would be overcome by the use of center-hole jetting. Horizontal loads would be resisted by an array of vertical piles joined by a pile cap, the bent acting as a rigid frame. The glacial nature of the subsoils in New York Bay are discussed, as well as the details of the structural challenge. The precasting is described, as well as the construction of the four transformer vaults.
