RFI Cycle Simulator
RL Framework · The RFI Doctrine

Routing-first RFI economics

Adjust the inputs to see what tightening RFI routing returns to your schedule. The model holds engineering response constant and varies only the routing and clarification portion of the cycle, where mission-critical programs often lose time.

Routing discipline iHow consistently RFIs are triaged, assigned, chased, clarified, and closed through the right owner path.
RFI impact profile iFrames the consequence of unresolved RFIs. It changes the advisory interpretation, not the base cycle-time math.
Cycle-time reduction per RFI 2.9 vs. current median
Routing Index 62 / 100
Moderate routing control. Watch field-blocking items.

At this profile, the model removes roughly ~13,000 RFI-days iA banded estimate of cumulative waiting load across all modeled RFIs, not a one-for-one schedule float recovery claim. The model treats about 70% of the median cycle as compressible routing and clarification time and holds engineering review constant; tune it to your own RFI logs. of waiting from the program. Treat that as a cumulative wait-load screen, not a direct float-recovery claim.

Foundations

This simulator draws on established RFI and project-controls practice:

  • Navigant Construction Forum — The Impact & Control of RFIs on Construction Projects (industry study on RFI volume, cost, and turnaround)
  • CSI / AIA construction contract administration — the RFI process and response obligations (A201 General Conditions)
  • CPM scheduling & delay analysis — AACE International recommended practices (how RFI latency reaches the critical path)
  • Lean Construction / Last Planner System — RFIs as lookahead constraints cleared before they block work
