Construction RFI Response Time Benchmarks: What the Data Shows
Industry data puts the average RFI at 10–15 days from submission to closeout. The teams that consistently hit under 5 days have changed three specific things. Here's what the numbers say.
The Benchmark: Industry Average RFI Turnaround
The most frequently cited industry figure is the Navigant Construction Forum's finding that the average RFI takes 9.7 review hours and $1,080 to process, with calendar-time closure averaging 10–15 days. Newer industry surveys from Dodge Construction Network and Procore data reports put average closure at 9–13 days depending on project size and delivery method.
The variance by project type is significant:
Average RFI Closure Time by Project Type
- Small commercial (under $10M): 6–8 days
- Mid-size commercial ($10–100M): 10–12 days
- Healthcare/institutional ($50M+): 12–18 days
- Large complex/public ($100M+): 15–25 days
- Design-build (any size): 20–40% faster than design-bid-build
Why RFIs Take So Long
Post-mortem RFI analysis from general contractors who track closure-time data typically identifies three sources of delay:
- Routing time (25–40% of total): The RFI sits in an inbox before anyone reads it. Most RFI platforms send a notification email; many recipients let those notifications pile up.
- Research time (20–35% of total): The designer spends time understanding what was asked, looking up references, and drafting an answer. This is where unclear RFI text and insufficient context hurt most.
- Coordination time (25–45% of total): The answer crosses disciplines—a structural RFI needs MEP input, an MEP RFI needs architectural confirmation. Each round-trip adds days.
Our guide to writing an RFI details the context that shortens research time.
Three Changes That Move the Needle
Teams that reliably close RFIs under 5 days have made three specific process changes:
- SLA by severity, tracked weekly: RFIs flagged as "schedule-critical" get a 48-hour SLA. Non-critical get 7 days. The metric is reviewed at every OAC meeting. SLAs without weekly review don't stick.
- Pre-submit review by GC: The GC reviews every RFI before it goes to the design team, returning unclear ones for clarification. This eliminates 15–25% of research time because designers receive better-written RFIs.
- Consolidated responses: Related RFIs are batched and answered together rather than sequentially, reducing coordination round-trips. The designer answers 5 related HVAC RFIs in one sitting instead of 5 separate responses over 3 weeks.
The Upstream Win: Fewer RFIs
The highest-leverage RFI optimization isn't faster response—it's fewer RFIs. Industry research puts 30–60% of RFIs in the category of "avoidable with better drawings." Teams that invest in preconstruction drawing review see 25–40% RFI reduction, which in turn reduces the backlog load on designers and shortens everyone's response time.
Our work on reducing RFIs and preconstruction ROI covers the math—every RFI prevented saves $1,000+ in direct cost plus an average 12 days of calendar time.
How Helonic Helps
Helonic reviews drawings for the conditions that typically generate RFIs—missing dimensions, inconsistent schedules, undocumented transitions, code callout conflicts—and pushes the resulting catches as draft RFIs into Procore and Autodesk Construction Cloud. Teams that adopt upstream AI review typically see a 30%+ drop in RFI volume within the first full project.
