Description
The MBTA is seeking a single‑source design‑build contractor to construct a new hi‑rail access tunnel for the Red Line at Alewife Station in Cambridge, MA. The scope includes full engineering, permitting, construction, and commissioning of a 15‑ft‑wide, sloping access tunnel, associated storm‑water management, site‑specific safety and security systems, and the removal/relocation of existing utilities. The contract is a lump‑sum award with an estimated construction cost of roughly $42 million and a schedule of about 1,027 days from notice to proceed. Key requirements include compliance with Massachusetts prevailing‑wage rules, extensive environmental monitoring (asbestos and contaminated‑soil), and strict adherence to the Base Technical Concept (no alternative access methods).
