The Green Line Extension (GLX) Project Team will hold a public “Open House” on Thursday, May 9, 2013 at the new GLX Project Office in Boston.

The Open House will take place from 5 to 7 p.m. at the GLX Project Office at 100 Summer Street (2nd Floor), near South Station.

The Open House is an opportunity to tour the new office, get updates on the project’s progress, meet the GLX project team and ask questions and provide feedback on the current state of the project.

There will also be a brief Project Update Presentation at 6 p.m.

The new GLX Project Office houses the MBTA GLX staff, the GLX Program Management Team HDR/Gilbane, the GLX Design Team AECOM/HNTB, and shortly the Construction Management/General Contractor Team (CMGC).

The Green Line Extension currently is Phase I of construction. In Medford, the work consists of widening the rail bridge over Harvard Street; replacing and/or relocating water and utility lines; constructing retaining walls and noise barriers; and relocating the commuter rail tracks near the bridge. Other Phase I work includes widening the Medford Street rail bridge in Somerville and demolition of an MBTA building in Cambridge on the site of the new Lechmere Station.

MassDOT Green Line Extension status report for April

12 April, 2013 (14:38) | News | By: Editor

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

Phase I Construction Progress
At the Harvard Street Bridge, early enabling work is under way, including creating access to the track elevation and preparing for excavation support along the track alignment, while utilities are moving their lines to the west side of the track, away from the upcoming work zone. Meetings are also ongoing with the abutters to minimize impacts where possible.

Phases 2-4 Project Phasing and Delivery
Proposals are currently due on April 22 from firms interested in the Construction Manager/General Contractor work for Phases 2 through 4 of the project, and the contract is currently scheduled for award at the July 2013 MBTA Board meeting. In addition, procurement of an Independent Cost Estimator (ICE) is underway, with Qualification Statements received on March 29, 2013. The Qualification Statements will be reviewed in April and a Request for Proposal sent to the most qualified firms. The ICE is also scheduled for approval in the June/July timeframe.

New Green Line Vehicles
Procurement of 24 new Green Line vehicles needed to support the operation of the Green Line Extension is ongoing. Proposals were submitted to the MBTA by two potential builders of the new Green Line vehicles on June 13, 2011. In March, the MBTA requested the two proposing teams update and re-submit their proposals as a Best and Final Offer to the MBTA.

Real Estate
Work is under way on certain property survey boundaries which are needed for any MBTA sliver takings, following completion of a confirmatory survey of the right-of-way limits that was used in the Advanced Conceptual Design efforts and as confirmation for typical sections, track layouts, and an update to the listing of the potential property impacts.

The parcels that the City of Somerville has acquired for the proposed Union Square Station site will be conveyed to the MBTA in early summer 2013 (previously: late spring 2013).

As a follow-up to the January 2013 coordination meeting with the Massachusetts Historic Commission (MHC) on the details of the viaduct demolition, a draft Historical American Engineering Report (HAER) was submitted in March 2013. Edits to the HAER are being completed and the final report will be submitted to MHC in mid-April.

Public Outreach
An overall Phase 1 public meeting was held on March 14, 2013 to discuss scope, schedule, contacts, the hotline, coordination with the Fire departments and proposed road detours (PowerPoint presentation here). The project team also continues to respond to inquiries to the project website with regard to scope, schedule and coordination. Pre-construction surveys of abutter properties and utilities are underway.

A Design Working Group/open house meeting will be held in early May at the new Project Office [100 Summer St., Boston] to update the group and the public on the status of the project’s design since its last meeting in November.
