Description

The Commonwealth of Pennsylvania seeks a qualified contractor to update the National Wetland Inventory (NWI) for the Pennsylvania Coastal Zone, focusing on the tidal Delaware River and surrounding intertidal mudflats in Bucks County. The effort requires GIS mapping, data‑gap analysis, field verification, integration of third‑party datasets, and delivery of updated NWI layers conforming to the Federal Geographic Data Committee (FGDC) Wetlands Mapping Standard. The contract will be a fixed‑price, sealed‑proposal award evaluated on technical merit (65 % weight), cost (35 % weight), and a small‑diverse‑business participation component, with an optional 3 % bonus for domestic‑workforce utilization. The contract term runs from the effective date through 30 June 2027, with possible two‑year extensions. • Update and validate NWI GIS layers for the PA Coastal Zone, emphasizing the tidal Delaware River. • Conduct spatial data‑gap analysis, prioritize field‑verification sites, and integrate third‑party data meeting NWI standards. • Produce a Quality Assurance Project Plan, quarterly progress reports, and a final technical report with deliverables in ArcGIS Pro format. • Meet extensive compliance requirements (insurance, background checks, domestic‑workforce utilization, small‑diverse‑business participation, and adherence to FGDC standards).

Budget estimate

$500,000 – $2,000,000

No contract ceiling is disclosed, but similar state‑wide wetland inventory updates typically range from $0.5 million to $2 million for a one‑year effort, depending on staffing levels, GIS licensing, field‑survey costs, and the extent of data integration. Assuming a mid‑size consulting firm with a modest team, the award could be around $1 million; larger firms or extensive field work could push the total toward $2 million, while a lean approach might stay near $500 k.
