Here are highlights of the October status report on the Green Line Extension project, which is to be presented to the Boston Region Metropolitan Planning Organization at its meeting on Thursday, October 18:
PROJECT DELIVERY
+ The MBTA has procured a new consulting team — a joint venture of AECOM and HNTB — that will extend the design through Advanced Preliminary Engineering (APE) and, upon approval from FTA, through Final Design. The team received a Notice to Proceed on September 20, and had a kick-off meeting with the Project Management/Construction Management team (HDR/Gilbane) on September 27.
+ The State Inspector General is anticipated to give final approval in fall 2012 for the use of the Construction Manager/General Contractor method on the Green Line Extension. This method already has been approved by the state legislature and MBTA board and signed into law by Governor Patrick.
STATION AND BRIDGE DESIGN
+ The MBTA is appealing a decision by the State Building Inspector in regard to the design of the emergency egress from the end of four station platforms (College Avenue, Ball Square, Lowell Street and Union Square).
+ Concurrence with the City of Somerville is needed on which of a series of design options should be selected that will allow the MBTA paratransit service to safely and conveniently access the new Green Line station at Gilman Square
+ Coordination continues with NStar and MWRA with regard to revised station layouts at Ball Square.
+ Drainage issues and solutions at Washington Street Station and the Red Bridge-NorthPoint area are being evaluated
+ Alternative methods to provide Traction Power are under study
+ A design for a relocated second entrance at Lechmere is under review
+ Options of how a future second headhouse could be added at the Union Square station have been developed and are ready for review with the City of Somerville.
+ The phasing of the roadway improvements at Lechmere (O’Brien Highway, North First Street and Water Street), which are the responsibility of the NorthPoint development project, continue to be discussed between the GLX team and the NorthPoint developer, and the design of O’Brien Highway an item of discussion between NorthPoint, the City of Cambridge, and the members of the East Cambridge neighborhood.
+ The project also continues to coordinate the Viaduct design with the Archstone II development and the 22 Water Street developer.
PHASE I EARLY BRIDGEWORK/DEMOLITION
+ Design work is complete for Phase I, which includes the widening of two railroad bridges (over Harvard Street in Medford and over Medford Street in Somerville) to accommodate the additional Green Line tracks, and the demolition of the MBTA tire storage building at 21 Water Street in the Lechmere area to provide parking and staging areas for the Phase 2/2A work.
+ A pre-award meeting was held with the apparent low bidder (Barletta Heavy Division, Inc.), and the General Manager is expected to award the contract for the Phase I work in late October/early November, with a Notice to Proceed and construction anticipated in late fall 2012.
+ A request for a Letter of No Prejudice, which would maintain eligibility for reimbursement from FTA for the Phase 1 work scope, was submitted to FTA on July 19, but early indications are that this request will not be approved. Consequently, this phase of the GLX Project will be funded completely by the Commonwealth of Massachusetts.
PUBLIC OUTREACH
+ Project staff has met with the majority of the abutters to the Phase I work, including the area around Harvard Street in Medford, as well as representatives of Tufts University, the City of Medford and the City of Somerville.
+ In the coming months, separate public meetings will be held to introduce the Advanced Preliminary Engineering team and the Phase I contractor to the communities.
PROJECT SCOPE/COST
+ Now that the Advanced Conceptual design has been completed, the MBTA is developing a new estimate of the scope of work to complete the project and is working to identify new cost and schedule risks, and mitigate those previously identified in order to complete the project for an amount less than the $1.115 billion estimate.
FEDERAL FUNDING
+ The New Starts application is scheduled to be completed in the late spring/early summer of 2013 for submittal to the FTA in September 2013 to match the federal review cycle of New Starts applications. Without progress on this issue, in this time frame, the application cannot be completed and the review cycle may be missed, delaying project approvals and the corresponding start and finish dates for Final design and Construction.
