AI Contract Overview

The Town of Plainville, Connecticut, is seeking qualified environmental engineering consultants through a request for qualifications labeled PLV RFQ 2027-04E to provide on-call services across multiple municipal facilities including the Building and Grounds complex, Former Town Landfill, Roadway Facility, and Water Pollution Control Facility. The scope of work centers on regulatory compliance and includes administration and monitoring of Industrial Stormwater Permits, MS4 Permit sampling, Landfill Stewardship activities, and RICA Permit requirements. Work is delivered on an as-needed basis through task orders under an indefinite-delivery arrangement, with no fixed term or estimated contract value specified. Services must align with Connecticut DEEP regulations and federal clean water standards, and the contractor may be tasked with completing pending industrial permit registrations left unresolved by prior consultants. The solicitation was posted on July 27, 2026, with responses due by August 14, 2026, and is administered through the Connecticut Department of Administrative Services Procurement office, with primary contact information provided via town purchasing channels. Performance locations are entirely within Plainville, and while no formal evaluation criteria, award methodology, or pricing structure are outlined, the emphasis is on technical expertise and regulatory knowledge rather than cost competitiveness. No contract clauses, representations, certifications, packaging requirements, inspection protocols, or detailed payment instructions are included in the solicitation materials, and the absence of a standard Section K or M suggests a streamlined, qualifications-based selection process is anticipated. Addendum #1 modifies the solicitation to clarify expectations around transitioning ongoing permit obligations but does not alter the fundamental structure of the on-call service model.
