RFI Response Rate

A coordination KPI for design and CM teams. Late RFIs often drive field delays and change risk.

Response % = on-time RFI answers ÷ RFIs issued × 100.

Tip: Keep “Answered in SLA” and “RFIs Issued” on the same basis (period, units, and population) before calculating RFI Response Rate.

RFI response rate measures how often RFIs are answered within the contractual or project SLA.

Enter on-time answers and RFIs issued for the same period.

Understanding RFI Response Rate

How we calculate. Response % = on-time RFI answers ÷ RFIs issued × 100. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.

Real-world scenario: A typical RFI Response Rate case uses answered in sla 42 and rfis issued 50. Enter the same figures below to reproduce the worked path.

What is RFI Response Rate?

A coordination KPI for design and CM teams. Late RFIs often drive field delays and change risk.

  • Define the SLA clock
  • Same issue set in both fields
  • Segment by discipline

The Formula

RFI Response Rate
Response % = (RFIs answered in SLA ÷ RFIs issued) × 100

Worked Example

Scenario: 42 on-time answers of 50 RFIs issued.
Step 1: 42 ÷ 50 = 0.84
Step 2: × 100 = 84%
Answer: RFI response rate is 84%.

Common Use Cases

  • Design team SLAs: answer speed
  • GC coordination: bottleneck RFIs
  • Owner reports: information flow

Pro Tips

  • Exclude withdrawn RFIs if policy says so
  • Track average days separately
  • Link late RFIs to delay logs

Limitations: RFI Response Rate results are educational construction planning aids—not engineering, safety, legal, or cost-estimating advice. Confirm definitions with your project controls, safety, and contract documents. For earned-value SPI/CPI see the Professional hub.

FAQ

Issued or open RFIs?

This form uses RFIs issued in the period as the denominator. Open-inventory variants need a labeled snapshot base.

What if RFIs issued is 0?

Response rate is undefined—enter a positive issued count.
