The Massachusetts Bay Transportation Authority Green Line Extension (MBTA GLX) Project Team has released a draft Request for Proposal (RFP) for the GLX Design Build (DB) contract to the short-listed DB teams. The draft RFP includes an affordability limit of USD 1.319 billion, base scope of work, and “additive options,” should a firm believe the options can be completed within the project schedule and the affordability limit budget. The final RFP will be issued in May 2017 after feedback is received from the design-build firms on the draft RFP.
“Teams hoping to participate in the GLX delivery effort must focus first on the core elements – seven stations and train service – before pricing out additional scope elements that would be welcome but not required to comply with the Project’s successful completion,” said Program Manager John Dalton.
Six additive options are included within the draft RFP that the competing design-build firms may propose under the affordability limit. Options must be added in in the following prioritized order: 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; enhanced Vehicle Maintenance Facility in Somerville.
Price proposals for the competing design-build firms are due in September 2017 and must not exceed the established affordability limit of USD 1.319 billion, which is a part of the overall GLX Program budget of USD 2.3 billion.
