Government contracts for plumbers in Michigan

Plumbers contracts in Michigan typically cover backflow-preventer testing, water-main repair, fixture replacement at federal buildings, sewer-line work at correctional facilities, and on-call plumbing IDIQs. Federal posts in this category fall under NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors), and the bulk of the work flows to the Army Corps of Engineers, the Federal Bureau of Prisons, and GSA. Small-business set-asides are common because most jobs sit well below the simplified acquisition threshold.

Michigan currently has 9 open plumbers contracts in our database, with 9 added in the last 30 days. That's a steady cadence — enough flow to make automated alerting worthwhile rather than manual portal-checking. The most active buyers are HRD (2 open posts) and Huron Valley Schools (2), with the rest spread across other federal civilian agencies, DoD components, and state and local departments active in Michigan.

Beyond federal opportunities, much of the plumbers work in Michigan is posted through SIGMA Vendor Self-Service (Michigan DTMB), with recurring buyers including the Michigan Department of Transportation and Michigan public universities. The Department of Technology, Management & Budget (DTMB) acts as the central buying authority — registering with DTMB exposes you to most state agencies. ContractRadar pulls federal postings from SAM.gov alongside state and local feeds so a plumbing contractor doesn't have to monitor each portal manually.
