The Massachusetts Department of Transportation is soliciting bids for the Boston - CANA Tunnel and Vent Building Rehabilitation project under solicitation number 606859-134231-100_811, with a total estimated contract value of $8,063,000. The work encompasses a comprehensive range of construction activities including plumbing, fire protection, HVAC, waterproofing, roofing, masonry, and painting, each with specific line-item pricing and technical requirements detailed in the contract documents. All work must comply with MassDOT’s Standard Specifications for Highways and Bridges, Supplemental Specifications, Special Provisions, and General and Supplementary Conditions, which are binding and not to be waived unless explicitly stated. The project is located in District 6, Massachusetts, and must be completed within 1,353 calendar days after issuance of the Notice to Proceed. Bidders must be prequalified with a valid MassDOT vendor code and possess a Digital ID obtained at least 14 days prior to bid submission, which is conducted exclusively through the www.bidx.com portal; paper bids are not accepted. To qualify for award, bidders must meet stringent eligibility and compliance criteria. Prime and sub-bidders must hold current DCAMM certification in the appropriate categories of work, specifically GENERAL BUILDING CONSTRUCTION or ELECTRICAL for prime contractors, and relevant classifications for subs. A bid bond of 5% of the bid amount is mandatory for all bidders, accompanied by required forms including the General Bid Form B00521 or Sub-Bid Form B00520, and signed update statements. Crucially, the contract mandates participation by Minority or Women-owned Business Enterprises (M/WBE) and Service-Disabled Veteran-Owned Business Enterprises (SDVOBE), which serves as a pass/fail gate for award; failure to meet stated goals or demonstrate good faith efforts renders a bid non-responsive or the bidder ineligible. Additionally, contractors must comply with Massachusetts prevailing wage laws, submit certified payroll and electronic reporting, adhere to equal employment opportunity requirements, and provide certifications confirming no debarment, suspension, or criminal history within the past three years. All materials must meet strict packaging and labeling standards per ASTM, ASME A13.1, and manufacturer specifications, with firestop systems requiring intact, legible documentation of testing agency classification. Final performance acceptance requires comprehensive field testing conducted in sequence from basic systems to full system integration, documented with interim and final reports approved by MassDOT Security,
