What Is a Request for Information (RFI)?
An RFI (Request for Information) is a formal question from the contractor to the design team during construction. It's how ambiguities, conflicts, and missing details in the drawings get resolved without stopping work.

When RFIs are needed
Drawings can't show every detail. When the contractor encounters a conflict (structural beam vs. ductwork), a missing dimension, an unclear specification, or a field condition that doesn't match the drawings, they submit an RFI. The design team responds with clarification, a detail, or a design revision.
The RFI process
Contractor submits a written RFI with the specific question, referencing drawing sheets and specifications. The architect routes it to the appropriate engineer. The engineer responds (typically within 7-10 days per contract). The response may be a simple clarification or may require revised drawings. All RFIs and responses become part of the project record.
Managing RFI risk
Excessive RFIs signal incomplete drawings — a well-coordinated set generates fewer. Slow RFI responses delay construction and generate delay claims. Owners should track RFI response times and hold the design team accountable. Contractors should batch related questions rather than submitting dozens of trivial RFIs that bury the important ones.
The bottom line
RFIs resolve drawing ambiguities during construction. Well-coordinated drawings generate fewer RFIs; prompt responses prevent delays.
