Preliminary work is underway on the primary heavy building contract for the Hudson Tunnel Challenge, in line with Danish civil engineering agency Cowi.
The Gateway Growth Fee awarded a design-build contract for the $284 million Hudson River Floor Stabilization Challenge to Kiewit subsidiary Weeks Marine earlier this yr. Cowi will function the design supervisor and engineer of file on the New York Metropolis job, the agency mentioned in an Oct. 29 information launch shared with Building Dive.
The work is a part of the $16 billion Gateway Program, which can double capability for Amtrak’s Northeast Hall rail section connecting New Jersey and New York Metropolis.
Design for the containment construction is underway, and building on a check cofferdam was accomplished in October, in line with Cowi. Building work is anticipated to start subsequent summer season.
The general Hudson Tunnel Challenge entails constructing a brand new two-track rail tunnel underneath the Hudson River between North Jersey and Manhattan, then rehabilitating the 110-year-old tunnel that was significantly broken by Hurricane Sandy in 2012. The decaying tunnel poses a bottleneck for New Jersey commuters and Amtrak passengers, and President Joe Biden known as the Gateway Program “one of many largest, most consequential tasks within the nation.”
Weeks Marine will modify and stabilize the soil within the shallow space of the river close to the Manhattan shoreline. This can put together the bottom for the tunnel boring machine that may excavate the brand new tunnel and make sure the riverbed is protected against disruption, in line with a LinkedIn submit from Omaha, Nebraska-based Kiewit.
Cowi is chargeable for creating a short lived containment construction to guard the riverbed from disruption as it really works with Weeks Marine and its floor enchancment subcontractor, Keller Group. Groups will full every of the 2 600-foot sections sequentially to attenuate affect on vessel site visitors, per Cowi.
The complete floor stabilization venture is anticipated to be full in 2027, in line with Cowi.
