DPW Street Maintenance Request for Aggregate Material - Similar 1

The City of Detroit Office of Contracting and Procurement issued a solicitation (RFQ No. 545989) for qualified vendors to supply fine and coarse aggregate materials, specifically stone, sand, and slag, intended for street maintenance under the Department of Public Works. The solicitation was posted on June 10, 2026, with quotes due by June 16, 2026. The contract will be established as a Blanket Purchase Agreement with a term of up to two years, subject to renewal by mutual agreement and Detroit City Council approval. Delivery of materials, totaling estimated quantities of 5,000 tons of MDOT 23A or equivalent stone, 1,000 tons of Sand 2NS, and 5,000 tons of Slag 22A BF/SF or equivalent, is expected within seven days of purchase order receipt, with shipments scheduled as needed. Bidders are required to quote per ton, and pricing must remain firm with actual quantities subject to available funding. Vendors must comply with detailed quality standards governing material composition and testing procedures, including ASTM, AASHTO, and MTM methods to confirm aggregate properties such as particle size distribution, moisture content, and durability. Awarded suppliers must furnish equipment for safe sampling and testing access. Insurance requirements include Michigan statutory worker’s compensation, employer’s liability coverage at $500,000 per occurrence/disease, and general liability coverage with at least $1 million per occurrence, naming the City as an additional insured. Bidders are required to submit complete documentation including notarized affidavits, certificates of authority, financial statements for the past three years, and insurance certificates. The evaluation favors the lowest total net bid but also considers past performance and experience; failure to provide all required certifications and disclosures may result in bid rejection. Invoices will be processed via the City of Detroit Vendor Portal with strict invoicing requirements linking to approved purchase orders and supporting documentation, with standard payment terms set at net 30 days. Work commencement requires both a Contract Purchase Agreement and a Standard Purchase Order, and noncompliance may result in payment delays or non-payment. The City encourages engagement with minority, women-owned, and Detroit-based businesses, and enforces compliance with local ordinances and ethical disclosures.
