Transport Fuel Service at Denison & Rockwell City DOT Locations

The Iowa DOT is soliciting competitive sealed bids from qualified fuel vendors to provide transport and delivery of diesel fuels (ULS #1 and #2), biodiesel additive, and seasonal winter/summer additives to the Denison and Rockwell City maintenance garages. Bids are to be submitted as a per‑gallon fuel margin that will be added to the daily DOT rack price; vendors must indicate whether each margin is positive or negative using the system’s additional items fields. The contract will run from award through 6/30/2027 with optional one‑year renewals up to a total of six years. Deliveries are FOB destination and must occur within one business day of order receipt. • Required deliverables: diesel #1, diesel #2, biodiesel additive (B99/B100), winter additive, summer additive – all priced as per‑gallon margins. • Mandatory attachments: specifications for winter and summer additives, BQ‑9000 Producer Certification, and confirmation of fuel‑margin pricing instructions. • Evaluation will be based on cost and other factors (staffing, schedule, past performance, capacity).
