Diesel Construction Equipment (DCE) Compliance Services

This contract pertains to the retrofitting or certification of diesel construction equipment to comply with MassDOT and DEP clean diesel regulations, requiring the installation of emissions-reducing technologies such as oxidation catalysts or particulate filters. The work is intended to ensure that equipment used on Massachusetts transportation projects meets current environmental standards, reducing harmful pollutants and aligning with state clean air initiatives. The contract is structured as a subcontract under NAICS code 811490, which covers other personal and household goods repair and maintenance, indicating the nature of the service as equipment modification rather than manufacturing or new procurement. Performance of the work is designated for District 4, though specific location details beyond that are not provided, suggesting the scope may cover multiple sites within the district. The solicitation was posted and the response deadline is set for August 25, 2026, with no set-aside designation indicated, meaning all eligible vendors may compete. The contract does not include a point of contact or full agency address details, and the primary focus remains on technical compliance through equipment upgrades rather than broad procurement or infrastructure development.
