This is a source guide, not a live bid board. BrostCo does not claim that a notice is open without checking its current official source. State and local buyers maintain separate portals.

Before preparing a response, identify the notice type. An RFI may ask for capabilities or other planning information without seeking an offer. Read the requested format, questions and response deadline in the notice, then decide whether a capability summary or a proposal is appropriate. Read FAR 15.201(e) on RFIs ↗
