DENVER — The Regional Transportation District board of directors last month approved a $343-million contract award to Graham, Balfour Beatty, Hamon Constructors (GBBH) to design and build the planned North Metro Rail Line to 124th Avenue.
The proposal commits GBBH to completing construction of the line from Union Station in Denver to 124th Avenue by January 2018, according to a release from RTD following the board’s Nov. 26 meeting.
The North Metro Rail Line plan calls for build-out to State Highway 7, but RTD staff had recommended the project be limited to 124th Avenue in the first phase of construction due to limited availability of funding for the project. GBBH has proposed, as part of their proposal, to build out the complete line.
“We had four sound proposals, but after thorough evaluation, the GBBH proposal provides the best value and allows us to make great strides toward completing another FasTracks project,” said RTD General Manager Phil Washington.
The GBBH team includes Stantec Consulting Services and Parsons Brinckerhoff on design, Zann and Associates as the Disadvantaged Business Enterprise lead, Communications Connections Consulting heading up public information, Transit Safety & Security Solutions leading system safety and Systems Consulting, LLC taking the lead on quality assurance, among others.
With the contract award approved by the board, the Notice to Proceed with the project will be issued later this month, with design and construction work slated to begin early next year.
The cost of the $343-million project will be financed by Certificates of Participation and built on property currently owned by RTD.
“This demonstrates RTD’s commitment to making investments in the northern suburbs as we keep FasTracks moving forward,” Washington said.
In addition to GBBH’s proposal to complete full build-out of the North Metro Rail Line to 162nd Avenue, the group also suggested options to extend the line from the planned 162nd Avenue statation to Longmont, an extension of the Northwest Rail Line from 71st and Lowell to 88th Avenue in Westminster, as well as extensions of three other rail lines in the RTD system across the Denver metro area.
This contract award comes after GBBH submitted an unsolicited proposal to RTD in February; four other “competitive” proposals were received after RTD’s procurement process officially solicited bids over the summer. GBBH’s proposal was selected from a group that included proposals from Bechtel/Herzog, North Metro Transit Solutions, a joint venture of Kiewit/Stacy and Witbeck, and URS Energy and Construction, Inc.
