Call 001 R19CN09

The Massachusetts Bay Transportation Authority is soliciting bids for the Vehicle Maintenance Facility Lift Replacements project in Boston, Massachusetts, under solicitation number R19CN09, with a project value of $10,100,000.00 and a NAICS code of 541511. The work centers on the design, installation, monitoring, and maintenance of temporary excavation support and protection systems to safeguard against soil and hydrostatic pressure, as well as superimposed construction loads. Key deliverables include engineered shop drawings and comprehensive analyses prepared and sealed by a qualified professional engineer, along with detailed documentation of existing site conditions via photographs or video to establish baseline evidence and prevent liability disputes. The system must be installed without damaging adjacent structures, pavements, or utilities, with mandatory vibration monitoring to mitigate impacts. Contractors are responsible for securing all necessary permits, especially for dewatering discharge, and for managing any contaminated materials in compliance with local, state, and federal environmental regulations. The project requires a registered engineer to conduct periodic inspections and approvals of all excavation support systems throughout the work. Bid submissions are due by 2:00 p.m. on Thursday, June 4, 2026, through the electronic portal www.bidx.com, and must acknowledge and incorporate all requirements from Addendum No. 1, including updated specifications, such as Section 02260 for excavation support and protection. Materials must meet specified ASTM standards: structural steel to ASTM A36, A690, or A992; steel sheet piling to ASTM A328 or A572; reinforcing bars to ASTM A615 Grade 60; and timber piling to ASTM D25 pressure-treated per AWPA C3. Seven-wire strand must comply with ASTM A416, Grade 250 or 270, and grout must achieve a minimum compressive strength of 4,000 psi. A $25,000 allowance is provided for hazardous materials removal, while two lump sum line items—0130.465 and 0130.466—for building and site work at two locations form the principal cost structure. All bids must be submitted electronically, and opening will occur publicly immediately after the deadline. The place of performance is in Massachusetts, and while the period of performance and delivery schedule are not specified, compliance with all technical, regulatory, and documentation obligations is
