Owner: Port Authority of NY & NJ
Completion Date: January 1, 2010
Categories: Construction, Modifications & Improvements

The Bayonne Bridge spans the Kill van Kull tidal strait from Staten Island, New York to Bayonne, New Jersey. The abutments require large fender systems to protect the bridge against boat traffic.

Weeks Marine’s contract for the New Jersey side fender system is similar to an earlier contract Weeks performed for the Staten Island side. The scope of work for the New Jersey side consisted of the installation of 25 ea. 43” diameter drilled shafts at a minimum of 10’ into competent rock. Each socket was flushed with reverse circulation and the material airlifted into a material scow. All of the material was considered contaminated and was disposed of accordingly.

Weeks then installed 36” steel pipe piles with rebar cages and concrete fill. Weeks completed this work in two lifts: first filling the rock socket and the second completed after the installation of the fiberglass fender. A tremie pipe with transit mix concrete pumped from the shore was used to fill each pile.
