The average construction project generates one RFI for every $25,000 of contract value — meaning a $500,000 project will see 20 RFIs before it's done. Each one that goes unanswered for more than 5 days has a 60% chance of causing a schedule impact, according to a 2025 Dodge Construction Network study.
An RFI is a formal written question submitted to an architect, engineer, or owner asking for clarification on contract documents. Done right, RFIs protect your schedule, prevent rework, and create the paper trail that supports change order claims when the answer adds cost or time.
An RFI is:
An RFI is not:
The pipeline: RFI submitted → answer received → if scope changes → change order submitted → signed → proceed.
Never perform extra work based on an RFI answer alone. The RFI documents the question; the change order authorizes the money.
Drawing conflicts: two drawings show different dimensions; architectural vs. structural conflict; MEP trades conflict in the same space; detail contradicts plan.
Specification gaps: product specified without manufacturer; reference to superseded standard; finish schedule incomplete; installation method not specified.
Field conditions: existing conditions don't match drawings; unexpected rock, groundwater, or buried utilities; hazardous material discovered.
Design ambiguity: scope boundary unclear; "as directed by architect" without criteria; "verify in field" without parameters.
Rule of thumb: If you're about to do something you're not 100% sure is correct and the consequence of being wrong is significant rework — submit an RFI.

[SVG line chart: RFIs per $1M vs. cost/schedule overrun % — Under 10: 3%/4%; 10–20: 5%/7%; 20–40: 9%/12%; 40–60: 14%/17%; 60+: 19%/22%]
Projects with 60+ RFIs per $1M average 19% cost overruns. High RFI volume = incomplete design documents = change orders incoming. Flag unusual volume to the owner in writing and ensure your log is battle-ready.

[SVG timeline: Ideal (2+ weeks before work) → Acceptable (1–2 weeks) → Late (under 1 week) → Too late (after work started)]
Submit RFIs 2+ weeks before work is needed. Review drawings for the upcoming 2 weeks every Friday. Never let a crew start work with an unresolved question.
Specific, well-written RFIs average 4-day response time. Vague RFIs average 11 days.
Weak: "Please clarify the structural drawings at the second floor. There seems to be a conflict."
Strong: "Drawing S-2.1 shows a W12x26 beam at grid B-4, while Drawing A-3.2 shows open ceiling at the same location. HVAC duct on M-2.1 routes through this area. Clarify: (1) Is beam required? (2) If yes, confirm revised HVAC routing. Contractor proposes installing beam per structural and rerouting duct 6" north — confirm acceptable. Response required May 20 to avoid impacting framing crew scheduled May 23."
Connect RFIs to change orders within 5–10 days of receiving the response. Don't wait until project end.
