Description

Imperial County’s Department of Public Works is seeking qualified engineering firms to provide on‑call, as‑needed plan‑checking services for a variety of civil‑engineering designs. The work will be awarded on a task‑order basis, with the consultant reviewing grading, drainage, street‑improvement, utility, traffic‑control, and related plans to ensure compliance with County standards, Caltrans guidelines, and applicable regulations. The contract is a one‑year initial term with up to four optional one‑year renewals, and firms must be DIR‑registered, meet prevailing‑wage and DBE requirements, and hold appropriate insurance. • Scope includes review of grading, drainage, utility, traffic, and associated hydrology/hydraulic/geotechnical reports. • Compensation is per‑sheet lump‑sum fees (to be proposed by the consultant) with milestone payment structure; fast‑track reviews available at higher rates. • Firms must provide licensed professional engineers, meet staffing minimums (Assistant County Engineer, Civil Engineering Assistant I), and submit all proposals via the PlanetBids portal by Jan 27 2026.

Budget estimate

$30,000 – $150,000

The solicitation does not disclose specific fee amounts; payments are based on per‑sheet lump‑sum rates that contractors propose. Assuming a moderate workload of 50‑100 plan‑check sheets per year at typical rates of $300‑$1,200 per sheet, total compensation could range from roughly $30,000 to $150,000 annually. Larger or fast‑track assignments could push the high end higher, while a lighter volume would keep the low end near $30K.
