Retaining Wall Design and Construction (MSE Walls)

The contract requires the design and construction of Mechanically Stabilized Earth (MSE) retaining walls that adhere strictly to AASHTO Section 11 standards and MassDOT specifications, ensuring structural integrity and long-term performance. A critical performance requirement is a maximum allowable settlement limit of 1 inch, which demands precise engineering and construction practices to prevent excessive ground movement and maintain alignment with adjacent infrastructure. The work is to be performed in District 4 under the oversight of the Massachusetts Department of Transportation, with the project classified as a subcontract and assigned the NAICS code 238990 for other heavy and civil engineering construction. The solicitation was posted on June 26, 2026, with a immediate response deadline set for the same date and time, indicating a closed or expedited procurement process. The place of performance is limited to District 4, with no specific city or state provided, though it is clearly within Massachusetts jurisdiction. The contract does not specify a set-aside type or organizational requirements, and no point of contact information is included in the data provided, suggesting that all procedural inquiries must be directed through MassDOT’s standard procurement channels.
