Selling to public works departments

Public works buys engineering and construction, paving and materials, heavy equipment, fleet, water and stormwater systems, traffic and street lighting, asset management and work order software, and solid waste services.

  • Read the capital improvement plan. Most major projects show up in a five- or ten-year CIP before they go to bid.
  • Know the divisions. Engineering, streets, fleet, solid waste and utilities often buy separately and have their own managers.
  • Follow federal and state money. Federal highway formula funds, state DOT grants and bonds pay for much local road work.
  • Get on the right lists. Prequalification with the state DOT and registration on city bid portals come first for construction and engineering work.

See our guide to selling construction services, heavy equipment and largest government fleets.
