A Request for Quotes (RFQ) is defined as an informal solicitation, not subject to formal bidding requirements as set forth in Minn. Stat. § 16C.02. To differentiate between regular bid solicitations and quote solicitations, the project title for quotes will have “Quote (RFQ)” behind the project number. Please check Bid Express® weekly if you are interested in providing a quote for these solicitations, as they will not be advertised the same as regular projects with St. Louis County Public Works.
