GBBH has proposed building out the complete North Metro Line to 162nd Avenue, but RTD staff recommended the first phase of the project be built to 124th with the funding that is currently available.
RTD said building to 124th as a first phase serves the majority of projected ridership for the corridor and, as additional funds become available, RTD can then exercise an option with the contractor and issue a notice to proceed to complete the line to 162nd.
GBBH's cost proposal to build the line to 124th is $343 million, which RTD will finance by issuing Certificates of Participation. RTD said building North Metro to 124th as a first phase allows it to utilize its own financing opportunities to fund the project.
The proposal commits to completing construction of the line from Union Station to 124th by January 2018.
"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.
