Request for Information (RFI)
A formal construction question used to resolve unclear, conflicting, or missing contract-document information.
What is Request for Information (RFI)?
A request for information, or RFI, is the formal process for asking the design team or general contractor to clarify the contract documents. Low-voltage RFIs commonly address conflicting device counts, missing riser information, unclear cable types, door-hardware responsibilities, unavailable equipment-room space, absent power, or differences between drawings and specifications. A useful RFI is specific and neutral. It cites the exact drawing, detail, specification section, or addendum; explains the conflict; states the schedule or cost impact when known; and asks one answerable question. Marked-up exhibits help reviewers understand the issue quickly. Contractors should not use an RFI to quietly rewrite scope or proceed on an undocumented assumption. Responses should be distributed to affected trades, reflected in estimates and submittals, and incorporated into record documents when they change the work.
