It appears that the first phase of construction of the Green Line Extension to Somerville and Medford will not cost as much as anticipated.
The MBTA received nine bids for the Phase I work, which consists of the widening of two rail bridges and the demolition of a T storage building, and on average they were $1.6 million under the MBTA’s estimated cost of $16.733 million. Of the seven below-estimate bids received, the average bid was $2 million under the projected cost.
Barletta Heavy Division of Canton submitted the lowest bid, $12.989 million, or $3.74 million under the estimated cost. The next lowest bidders were LM Heavy Construction of Westford at $13.472 million ($3.26 million under), and MIG Corporation of Acton at $14.57 million ($2.18 million under).
Phase I work will consist of three elements:
+ In Medford, the reconstruction and widening of the Harvard Street railroad bridge (New Hampshire/Lowell Line), retaining wall/noise barrier construction, track relocation, and ancillary utility and roadway improvements
+ In Somerville, the widening of the Medford Street railroad bridge (Fitchburg Line)
+ In Cambridge, the demolition of the MBTA-owned tire facility building at 21 Water Street
Ground-breaking on the project could take place this fall.
