MassDOT Green Line Extension status report for May

14 May, 2013 (23:07) | Documents, News | By: Editor

MassDOT has posted the May status report on the Green Line Extension project. Below are highlights of new information since the April report:

Phase I Construction
At the Harvard Street Bridge in Medford, enabling work is complete, including creating access to the track elevation, and installation of excavation support along the track alignment. Retaining wall work excavation is ongoing and AT&T and NGrid Gas have completed moving their lines away from the work zones.

A Phase 1 partnering workshop was held in April with representatives from the MBTA, the Program Management/Construction Management team (HDR/Gilbane), the Owner’s Representative, the Contractor, and representatives from each of the Cities of Cambridge, Somerville and Medford.

Design Progress
The AECOM/HNTB design team has continued to advance design on all portions of the program and has made an interim submittal of some 4,000 drawings for review and coordination by MBTA and the Program Management/Construction Management  team (HDR/Gilbane) for the use in an intermediate risk analysis and for the start of the update to the program estimate.

Project Phasing and Delivery
Proposals were submitted on April 22 from three joint ventures wishing to be considered for the Construction Manager/General Contractor contract for Phases 2, 3 and 4 construction. The proposals are currently being reviewed by the selection committee with interviews scheduled for May 16. The contract is currently scheduled for award at the July 2013 MassDOT/MBTA Board meeting.

Procurement of an Independent Cost Estimator (ICE) is under way. Qualification Statements were received on March 29, 2013, reviewed in April, and a Request for Proposal will be sent to the most qualified firms. The ICE Contract is scheduled for approval by the MBTA General Manager in the June/July timeframe.

Real Estate
Certain pre-acquisition activities continue, including the work associated with the title surveys and appraisals for the anticipated full-property acquisitions including those needed for the Vehicle Maintenance facility and at the Ball Square Station location. The Project team continues to issue Right of Entry notices to support both the survey and boring activities and to coordinate with the property owners at those locations. The property acquisition and relocation activities are critical to the start of construction and completion of the maintenance facility [Phase 3].

The team also has been working with the City of Somerville in regard to an agreement to use the Homan’s building site to support construction at the Medford Street Bridge and for the construction of the Gilman Station. Design coordination and resolution of conflicts associated with the concepts generated by the City’s “Somervision” planning process is ongoing and revised property plans are being prepared for parcels at Gilman Station and Ball Square Station.

An appraisal is underway in regard to the NStar property needed by the project on the High School side of the Gilman station area. The project team is also continuing to coordinate with NStar on designs for the provision of power to the traction power substations at Red Bridge, the Maintenance facility and at Gilman Square as well as interface on utility and streetscape issues with HYM and 22 Water Street in Cambridge.

Public Outreach
A Design Working Group/open house meeting was scheduled for early May at the new Project Office to update the Group and the public on the status of the project’s design since its last meeting. An additional round of station workshops is being scheduled for late May and early June [actually, June 3 through June 20; full schedule here  ].
