ARC tunnels package revised Nov 2009
Paula Wallis, TunnelTalk
The 100ft deep Hoboken access shaft on the ARC project in New Jersey has been taken from the project's Hudson River Tunnels contract and included in its Palisades Tunnels package. The two contracts interface at the Hoboken shaft and moving its construction to the Palisades Tunnels package will optimize project scheduling.

The Palisades contract is the next of the project’s three major design-build tunneling packages to bid and its twin TBM tunnels will bore about 5,200ft (1,584m) through the hardrock of the Palisades to finish at the Hoboken access shaft. The twin bored tunnels under the Hudson will start at the same shaft and end at the Twelfth Avenue shaft in Manhattan.
Bids for the Palisades Tunnels contract are due in mid-December. Four joint ventures have pre-qualified for the contract - OHL/Tully JV, Barnard/Judlau JV, Shea/Schiavone/Skanska JV, and ARC Constructors, a JV of S.A. Healy/CCA Civil/Halmar.
Pre-qualification is underway for the $250 million-plus design-build Hudson River Tunnels. Pre-qualification for the contract remains open for interested design-build contractors. Pressurized face TBM technology, capable of both hard rock and soft ground, will be needed to excavate the twin 7,400ft (2,255m) long tunnels under the river.
Last week (Nov 2009), the Barnard/Judlau JV submitted the apparent lowest bid of the project’s first design-build tunnel contract. The JV’s $583 million bid for the Manhattan Tunnels contract narrowly undercut the $584.5 million from the Shea/Schiavone/Skanska JV. ARC Constructors submitted a third bid of $598 million. Those bids are now being evaluated ahead of confirmation and notice to proceed.
Construction of the 9-mile (14.5km) ARC project began in June 2009. The project is the largest mass transit infrastructure project currently underway in the United States and will increase commuter capacity from the New Jersey region into Manhattan. New Jersey Transit and its partner the Port Authority of New York and New Jersey are owners of the project.
