Description

The Washington State Department of Transportation (WSDOT) is seeking a total‑small‑business set‑aside vendor to provide post‑construction environmental compliance monitoring for the OR FLAP GRANT 24(2) Granite Hill Road Reconstruction Phase II. The scope includes routine inspections, turbidity monitoring, sediment removal, maintenance of erosion controls, and documentation of the Environmental Stormwater Compliance Plan (ESCP). Work is performance‑based; the base contract covers predictable activities while any extensive repairs, specialized equipment use, or unforeseen conditions will be handled via contract modifications or separate bid items. The effort is weather‑ and site‑condition dependent, with an anticipated inspection period from November 2026 through November 30 2027.

Budget estimate

$500,000 – $1,500,000

No contract value is disclosed. Based on typical post‑construction environmental monitoring contracts for a multi‑mile road reconstruction, the budget is likely in the mid‑six‑figure range, covering labor, travel, equipment, and occasional sediment‑removal work. A reasonable estimate would be between $500,000 and $1,500,000 for the 12‑month period, with the lower end reflecting a minimal‑maintenance scenario and the higher end accounting for multiple corrective actions, turbidity events, and sediment disposal costs.
