A Request for Information (RFI) is a formal query from a contractor to the project designer (architect or engineer) seeking clarification about construction documents. RFIs address ambiguities, conflicts between drawings, missing information, or questions about design intent. The designer responds with clarifications that become part of the project record. Efficient RFI management prevents construction delays and ensures work proceeds correctly. On municipal capital projects, numerous RFIs are common as contractors work through detailed construction documents. In procurement contexts, RFI can also mean a preliminary request for market information before issuing formal requests for proposals.
