Construction RFI Response Time Benchmarks: What the Data Shows

What is the industry-average RFI turnaround time?

The most frequently cited industry figure is the Navigant Construction Forum's 2013 study, which found the average RFI takes roughly 8 hours of combined administrative and technical review time and costs about $1,080 to process, with a median closure time of 9.7 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:

Why do RFIs take so long to close?

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.

Which three process changes close RFIs under five days?

Teams that reliably close RFIs under 5 days have made three specific process changes:

1. 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.
2. 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.
3. 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.

What is the highest-value RFI improvement?

The highest-value RFI improvement is fewer RFIs, because every avoided question is time the design team never spends in the queue. 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 roughly 9–13 days of calendar time.

How does Helonic help reduce RFI volume and response time?

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.
