Description

The State of Oklahoma is seeking qualified contractors to perform the complete closure of four total‑retention lagoons (A, B, C, and D) at the Greer Campus in Enid, OK.

The solicitation includes a mandatory pre‑bid conference, waivers of the usual 14‑day pre‑opening submission requirement, and strict compliance with Oklahoma construction statutes and environmental regulations. • Scope: Demolition, excavation, grading, fill placement, seeding, erosion control, and site security. • Schedule: Pre‑bid conference July 17 2026; bid deadline August 20 2026; work must start within 10 days of notice to proceed and be finished within 232 days. • Requirements: Electronic bid submission, bid‑security (5 % if > $100 k), non‑collusion certifications, and submission of CAP Form A305.

Budget estimate

$200,000 – $300,000

The project manual cites an estimated cost of $250,000 for the lagoon‑closure work. Considering typical contractor overhead, profit margins (10‑15 %), and potential change‑order adjustments, a realistic award amount is likely to fall between $200,000 and $300,000. The lower bound assumes a tight bid and minimal contingencies; the upper bound accounts for higher‑value fill, equipment, and risk factors.
