Before you start: 3 tips for getting on bidder lists
- Get on each agency's list. Public jobs from $75,001 to $220,000 often go out by informal bid, sent only to contractors on the agency's own list. Not on the list, no invitation.
- Pick your license classes and work categories carefully. That's how agencies decide who gets each invitation.
- Renew every year, and keep your DIR registration current. Many lists run by calendar year, so check each one in November and December. Every public-works bidder also needs a current DIR registration (a separate state requirement).
Click an agency for its full guide and its official pages, and always confirm there: agencies change these often. The free weekly list shows "Lists opening this month" so you don't miss a window.
