Plan holder lists
When a state DOT or a city bid page prints the prospective bidders in public HTML, that list becomes one GC opportunity on the underlying job. You see the company name. Email and phone show up only if the agency printed them on that same page.
Public sub solicitations
Good-faith DBE, MBE, and WBE notices, and GC pages that ask for sub quotes in the open, are a separate source. DozerDesk reads the GC, the project, the scopes, the due date, and the contact as published. A page behind a login is skipped.
Packages posted here
A general contractor posts a sub bid package at no charge: project, location, scopes, quantities, due date, a plans link, pre-bid notes, and bonding, insurance, or DBE requirements. An operator approves it before it reaches your board. General contractor accounts stay free and never see the agency board.
