Call 002 R19CN09

The Massachusetts Bay Transportation Authority (MBTA) is soliciting bids for Vehicle Lift Replacements at its Boston, Massachusetts facility under solicitation number R19CN09, with a posted date and response deadline of June 4, 2026. The project, classified as Class 1 - General Transit Construction and governed by NAICS code 541690, has an estimated value of $10,100,000.00 and involves comprehensive building and site work at two designated locations. The scope requires the design, furnishing, installation, monitoring, and maintenance of temporary excavation support and protection systems capable of withstanding soil pressure, hydrostatic forces, and construction loads. Contractors must provide professional engineering services including signed and sealed shop drawings and a detailed engineering analysis, along with qualification data for both the installer and the responsible engineer. Surface water control through grading or dikes, vibration monitoring to safeguard adjacent structures and utilities, and installation practices that prevent damage to existing infrastructure are mandatory. The contract includes a $25,000 allowance specifically for transportation and disposal of hazardous materials, while demolition and excavation material handling costs must be absorbed within the lump sum pricing for the two primary line items. All excavated materials must be tested to determine proper disposal protocols in compliance with local, state, and federal environmental regulations, and contractors are fully responsible for securing necessary permits and managing dewatering discharge points as outlined in their approved plan. The project demands strict adherence to material specifications, including ACI 301 for cast-in-place concrete, ASTM A615 Grade 60 deformed reinforcing bars, minimum 4,000 psi grout, and ASTM A416 low-relaxation seven-wire strand. Proposals must be submitted electronically via www.bidx.com by 2:00 p.m. on the deadline date, and bidders are required to include a geotechnical report for informational purposes, detailed photographic documentation of existing site conditions, and complete qualification records.
