Description

The Town of Plainfield, Connecticut is seeking qualified civil/environmental engineering and GIS consulting firms to develop, standardize, and maintain the municipality’s separate storm sewer system (MS4) data. The work includes creating GIS data layers, performing outfall screening and monitoring, documenting findings, and providing annual reporting support under the state MS4 program. The scope is split into two sections so the town can evaluate price and qualifications separately; either or both sections may be awarded to a single consultant or to different firms, and the town reserves the right to phase, reduce, or not award the work. • Develop and standardize MS4 GIS data for the Town of Plainfield. • Conduct required outfall screening, monitoring, and documentation. • Provide annual reporting support to satisfy Connecticut MS4 compliance. • Submit separate pricing for each of the two defined sections, with an option for a combined price. • Potential for award of one or both sections, or no award, based on funding and evaluation.

Budget estimate

$150,000 – $500,000

Based on typical municipal GIS and environmental engineering contracts of this scope, the town is likely to allocate between $150,000 and $500,000 for the full effort. The lower end reflects a minimal data‑development package, while the higher end accounts for comprehensive outfall screening, ongoing annual reporting, and the possibility of awarding both sections to a single firm. Factors influencing the final amount include the depth of data standardization required, the number of outfalls to be screened, and any additional consulting hours needed for compliance reporting.
