RFI Cost Calculator

Calculate the true cost of RFIs on your construction project. The average RFI costs $1,080 to process and takes 10–15 days to resolve (Navigant/CII).

How This Calculator Works

This calculator uses the Construction Industry Institute (CII) 1-10-100 rule: a $1 issue caught in design costs $10 in construction and $100 in operations. Default values are based on:

  • $1,080 per RFI — Navigant Construction Forum™ study average processing cost
  • 10–15 day resolution — industry average turnaround including review cycles
  • 30–50% preventable — CII research on RFIs caused by drawing errors and missing information

Delay costs vary significantly by project size and type. Adjust the daily delay cost to match your project's general conditions rate.
