One (1) Year’s Requirements of Limestone – Various State Specifications

The Macomb County Purchasing Department is soliciting sealed bids for a one-year limestone supply contract covering the period from October 1, 2025, through September 30, 2026. The procurement seeks three specific limestone types: 23A Modified Limestone (60,000 tons delivered/105,000 tons spread), 6A Limestone (900 tons), and Chip Limestone (150 tons). Delivery locations include multiple Macomb County Department of Roads service centers in Washington Township, New Haven, Clinton Township, and Shelby Township, with options for on-site delivery and spreading. The limestone must fully comply with Michigan Department of Transportation (MDOT) 2012 Standard Specifications for Construction, with specific grading requirements mandating 100% crushed material. Bidders are required to provide gradation test copies for each material delivery and complete detailed unit price sheets. The bid submission deadline is September 18, 2025, with deliveries expected during specified hours of 7:30 a.m. - 2:30 p.m. The contract includes potential two one-year extensions, allowing for a total possible contract duration of three years.

The procurement opportunity appears to be open to all qualified vendors without specific set-aside designations for disadvantaged enterprises. Bidders must comply with several key administrative requirements, including the Federal E-Verify Program, Iran Economic Sanctions Act, and local preference guidelines. While specific budget ranges are not explicitly stated, the total projected limestone volume suggests a substantial contract value, with approximately 61,050 total tons of limestone anticipated. The County will not accept fuel surcharges, and delivered quantities cannot exceed purchase order quantities by more than 10 tons without prior approval. Vendors must provide computer-printed weight tickets and demonstrate capability to meet the comprehensive technical specifications outlined in the bid document. The procurement approach allows for competitive pricing across different yard locations and delivery methods, providing flexibility for both the County and potential suppliers.
