Government contracts for plumbers in Indiana

Plumbers contracts in Indiana 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.

As of October 20, 2026, Indiana has 1 open plumbers contract in our database, with 1 added in the last 30 days. Volume in smaller markets is lumpy: a single base or facility can drive a quarter of annual postings. The most active buyer is Federal Subcontract (1 open posts), but contracts also come from federal civilian agencies and state-level departments operating in Indiana.

Beyond federal opportunities, much of the plumbers work in Indiana is posted through the IDOA Online Procurement system, with recurring buyers including the Indiana Department of Transportation and Indiana University / Purdue. The state's Department of Administration (IDOA) runs a centralized vendor registration that all agencies pull from. ContractRadar pulls federal postings from SAM.gov alongside state and local feeds so a plumbing contractor doesn't have to monitor each portal manually.
