02How to get on the bid list

Big projects are not usually tendered trade by trade in public. The owner hires a general contractor or construction manager, who then prequalifies trades and sends out packages. Getting on that list early is how you get the call.

  1. Find out who the general contractor or construction manager is.
  2. Prequalify on their trade-partner portal (insurance, safety record, references).
  3. Ask when the packages for your trade go out, and to be on the invite list.
