Description

The Town of Plainfield is soliciting proposals for a multi-year municipal separate storm sewer system program with two separately priced sections. Section 1 covers stormwater GIS data auditing, standardization, geodatabase development, desktop digitization, outfall and interconnection inventory, targeted GPS-enabled field verification, catchment and receiving-water mapping, dashboards and mobile field tools, quality assurance, staff training, and complete data/configuration handoff. Section 2 covers permit-compliant outfall screening and monitoring, dry-weather and impaired-water sampling, laboratory coordination, illicit-discharge follow-up, records management, GIS updates, and preparation of Connecticut MS4 annual-report materials. The initial term is one year with up to three one-year renewals by mutual written agreement, subject to performance, continuing need, and annual appropriation. Proposals may address either or both sections and must include technical approach, staffing and qualifications, comparable project experience, at least three client references, GIS and technology details, schedule, pricing, certifications, and insurance capability. The selected consultant must support Town ownership and export of editable data, avoid proprietary lock-in, and meet specified regulatory, security, reporting, and deliverable requirements.
