Sound Transit reviews six bids for Northgate Link light rail extension

Sound Transit opened six bids for the contract to mine 3.4 miles of twin light-rail tunnels between Husky Stadium at the University of Washington and the Northgate Mall area in Seattle, Wash.

The engineer's estimate for the work was $594,803,500. The six bids ranged from $440 million to $517 million.

The apparent low bidder was JCM Northlink LLC, a joint venture formed by Jay Dee Contractors of Livonia, Mich.; Frank Collucio Construction Company of Seattle and Michaels Corporation of Brownsville, Wis., with a bid of $440,321,000. JCM recently completed work mining the light-rail tunnels between downtown Seattle and Capitol Hill Station as part of the University Link project.

"We are very pleased with the competitive response from the contracting community on this important contract for the agency that could save taxpayers millions of dollars," said Ahmad Fazel, Sound Transit executive director of design, engineering and construction management.

Sound Transit will now evaluate the bids to determine the lowest responsive and responsible bidder. This process ensures that the low bidder meets all contract requirements. After that has been determined, staff will bring a recommendation to the Sound Transit Board to approve awarding the contract this summer.

The contract is the largest single piece of work on the $2.1 billion Northgate Link Extension project. In addition to the twin tunnels, it includes excavating the underground stations in the Roosevelt and U District neighborhoods.

Sound Transit set a goal of eight percent of the contract amount to be performed by small businesses and four percent to be performed by disadvantaged business enterprises.

The winning contractor will launch two tunnel boring machines from the Roosevelt Station site to excavate the tunnels to the U District Station and on to the University of Washington Station at Husky Stadium. A third tunnel boring machine will be launched from the Maple Leaf Portal near NE 94th Street and will bore two tunnels, one after the other, to the Roosevelt station. The work is scheduled to begin late this year and last a little more than four years.

Different Sound Transit contractors began preparing the Roosevelt Station site last summer and recently began demolition of existing buildings at the U District station site.

The Northgate Link project is scheduled to open in 2021 and will connect with the University Link tunnels to downtown Seattle. The University Link section is scheduled to open in 2016.
