DBE Goal: 20% DBE Owner: Federal-State Description: The Massachusetts Bay Transportation Authority is soliciting Engineering and Design Consulting Services 30%-100%, Bid Phase and Construction Phase Services for the Green Line Central Tunnel Track, Power and Signal Transformation Project. The Scope of Service(s) may include but are not limited to: infrastructure assessment; light rail signal system upgrade; light rail track renewal; light rail traction power; transportation planning; multidiscipline engineering (i.e. civil, structural, electrical, mechanical and communication); environmental services; transit service planning; urban transit underground construction management; and robust stakeholder and public participation. The Green Line Transformation Program (GLT) seeks to optimize system identity and transform the Green Line light rail system to become a prime model of a contemporary, legacy transit system through innovative design, advanced operation, consistent preservation, and reimagined service. The primary purpose of this project is to modernize the Central Tunnel, upgrade track, track systems, infrastructure, power and signal systems, improve structural resiliency, and enhance capacity within the tunnel. Along with that is being able to facilitate both single and double car operation of the new Green Line Type 10 "Supercars" (T10). This modernization and transformation of the GL Central Tunnel area is expected to help the MBTA meet all the requirements for the Federal Transit Administration (FTA) CIG Core Capacity grant.
