Columbia Junction Signal Replacement Project
The MBTA Board of Directors awarded MBTA Contract Q40CN01 entitled “Columbia Junction Signal Replacement Project” to Barletta-Fischbach Joint Venture in the amount of $42,980,000.00. The Authority issued a Notice to Proceed on December 21, 2011.
The Columbia Junction Signal Replacement Project is a potentially forty-one-month program that will consist of the following: replacement of the wayside signal equipment, track turnouts and ties for the interlocking system between Andrew and North Quincy Stations on the Braintree Branch and Fields Corner Station on the Ashmont Branch; install and place in service a new cable trough / raceway system within those boundaries; and install and commission a new central terminal house (CIH), which will interface with the existing CIHs and the new wayside equipment to include the installation of fiber cable throughout the limits of this project.
Phase 1 of this Project will consist of night work; however, the majority of the work will be performed during pre-approved revenue service diversions (weekend shutdowns). At this time, thirty-five (35) scheduled revenue service diversions planned for the Columbia Junction Signal Replacement Project, which began in March 2012, have been completed. Several of the planned scheduled diversions have been re-sequenced due to scheduling conflicts as well as unforeseen site conditions while excavating for the track. Extra work was required in order to complete the track reconstruction. This re-sequencing of Phase 1 of the Project will conclude in Winter 2014. During planned revenue service diversions, the MBTA will be provide bussing services to accommodate all passengers between Andrew and North Quincy Stations on the Red Line's Braintree Branch and Fields Corner Station on the Ashmont Branch. Phase 2 of the Project will not include any scheduled revenue service diversions nor will it include any planned disruptions in service.
