Limestone Chips & Erosion Stone

The Iowa Department of Transportation (Iowa DOT) has issued a Request for Bid (RFB) solicitation number 645-RFB-2181-2026 for 3/8" Limestone Chips and Erosion Stone to be delivered to multiple DOT garages across Iowa. The procurement seeks to establish a price-based contract for materials to be ordered on an as-needed basis, with six specific line items covering limestone chips for garages in Sac City, Rockwell City, Ida Grove, Denison, and Storm Lake, plus an additional line item for erosion stone. The contract will be valid for one year, from November 6, 2025, to November 5, 2026, with an option to renew for five additional twelve-month increments. Bid submissions are open from October 16, 2025, at 2:00 AM CDT and will close on November 6, 2025, at 1:00 PM CST, with the bid opening conducted via Microsoft Teams. Award selection will be based on the most advantageous bidder, considering factors such as cost, mandatory requirements, proposed staffing, time schedules, past work performance, and work capacity. Delivery requirements specify F.O.B. Destination, with deliveries permitted between 7:30 a.m. and 3:30 p.m. on normal working days, and a 24-hour prior delivery notification is mandatory.

The solicitation does not explicitly mention specific set-aside designations or restrictions for disadvantaged enterprises. Deliveries will be F.O.B. Destination, with the Iowa DOT reserving the right to select delivery points, their geographical locations, and the tonnage awarded to any bidder. Payment terms are set at 0% 0, Net 60, and the department is a tax-exempt agency. Contracted suppliers must provide contact information for ordering locations, and invoices will be processed and emailed by field offices. While the specific budget range is not detailed in the documentation, the contract structure suggests a flexible, as-needed procurement approach with potential for significant material purchases across multiple Iowa DOT garages. The procurement allows for potential multi-year engagement through the initial one-year contract and the option for five additional twelve-month renewals, which could represent a substantial ongoing business opportunity for the selected vendor(s).
