Description

This contract awards Fauquier County’s on‑call stormwater and MS4 engineering services to four qualified firms for a one‑year initial term, with the option to renew up to three additional years. The work encompasses design, analysis, permitting, and compliance support for wetlands, storm‑water management, and the Municipal Separate Stormwater System (MS4) program across the county. The award is structured as an indefinite‑delivery, on‑call arrangement, allowing the county to call on any of the awardees as project needs arise. • Two primary contract scopes: (I) wetlands & storm‑water engineering (Dewberry Engineers) and (II) MS4 engineering (Rinker Design Associates). • Additional firms (Timmons Group and Wetland Studies & Solutions) are also on‑call providers under the same award notice. • Initial term is one year starting 6/29/2026, with up‑to‑three optional one‑year renewals, giving a potential total duration of four years. • No monetary values disclosed; the contract is an on‑call/IDIQ format typical for engineering consulting services.

Contract value

$2,000,000

The notice does not disclose a contract value. Typical on‑call engineering services for a county of Fauquier’s size range from $300k to $600k per vendor per year, depending on project volume. Assuming an average of $450k annually for each of the four awardees, the initial one‑year award pool would be roughly $1.8 million. Including the possibility of three renewals (up to four years total) could raise the cumulative exposure to about $7.2 million. Therefore, a reasonable ballpark estimate for the initial award is $2 million.
