mbta-green-line-extension-contract-revealed-november-17-2017The MBTA Green Line Extension project team today held a “price opening” to select the design-build firm that will perform the design and construction for the Green Line Extension.

The winning team is a Joint Venture of GLX Constructors, with a price offering of $954,618,600.  The bid includes all six additive options, meaning that in addition to track infrastructure and seven station stops, construction will include platform canopies, additional elevators at select stations, public art, additional community connection to the community path located on Chester Street in Somerville, extension of the community path between East Somerville and Lechmere Stations and an enhanced vehicle maintenance facility in Somerville.  On Monday, the Fiscal and Management Control Board will be asked to accept staff’s recommendation of GLX Constructors for a total contract price of $1,082,118,600, which includes the proposal price, all six additive options and MBTA contingency.

mbta-green-line-extension-contract-revealed-2-november-17-2017“With today’s price opening and the identification of the apparent successful Design-Build Proposer for the GLX, we are truly on our way to making the Green Line Extension a reality for the people of Cambridge, Somerville and Medford,” said MBTA General Manager Luis Ramirez.  “The selection process was extensive and thorough, and we are pleased that the outcome is that the cost is under our Affordability Limit.” The Affordability Limit set for the project, including contingency, is $1.319 billion.

In the approximately two years since the Green Line Extension Project was indefinitely paused due to cost overruns, the MBTA redesigned and restructured the delivery model for service to Cambridge, Somerville and Medford in 2021. After seeking qualifications from interested firms, the final step in the extensive procurement process was today’s opening of the price proposals from the two remaining design-build teams, (a third team did not advance to the final stages of the procurement).

The MBTA utilized a “best value” evaluation model in determining the team to deliver the future Green Line rail service.  Doing so required utilization of a state-mandated formula where the price offered by a team is divided by the team’s “Quality Score,” an assignment of points based upon the team’s response to the Requests for Proposals.

In an effort to guard against similar cost overruns that challenged the GLX project in the past, the MBTA implemented measures to institute strict cost controls throughout the procurement.  By implementing an Affordability Limit (the maximum allowable price for a proposal) and incentives for the inclusion of additive scope options (while not exceeding the Affordability Limit), the MBTA was able to procure the maximum project benefits without jeopardizing the project’s budget.

“We could not have asked for a better outcome from today’s price opening,” said Green Line Extension Project Manager John Dalton.  “The difficult decisions in 2015 and 2016 following the project’s shutdown in 2015 have paved the way for getting us to this point.  All of the effort that has gotten us to this point is well worth it. We now look forward to working with the residents, businesses, community stakeholders, and the successful Design Build team to completing the project on time and on budget.”

The contract which would be executed with GLX Constructors needs approval by the MBTA Fiscal and Management Control Board and a vote is scheduled for Monday, November 20.  The contract includes a base scope of work and “Additive Options” that were only to be included if they could be completed within both the project schedule and the Affordability Limit. The prioritized Additive Options to be included in the GLX Project are:

  1. Platform canopies.
  2. Additional elevators at select stations.
  3. Public art.
  4. Additional community connection to the community path located on Chester Street in Somerville.
  5. Extension of the community path between East Somerville and Lechmere Stations.
  6. Enhanced Vehicle Maintenance Facility in Somerville.

GLX Constructors is comprised of the following firms: Fluor Enterprises, Inc., The Middlesex Corp., Herzog Contracting Corp., and Balfour Beatty Infrastructure, Inc.
