Construction RFI Guide: Write, Submit, and Track

Every contractor has been there. You are looking at the plans, something does not add up, and your crew is waiting for an answer before they can keep working. That is exactly when you need a construction RFI.

An RFI done right gets you a clear answer fast. An RFI done wrong sits in someone’s inbox for two weeks while your project bleeds money. This guide covers how to write RFIs that actually get answered, how to track them, and how to stop them from killing your schedule.

If you are already familiar with the basics and want to learn how to manage RFIs across multiple projects, check out our construction RFI management guide.

What Is an RFI in Construction?

RFI stands for Request for Information. It is a formal written question from one party on a construction project to another. Most often, the general contractor sends an RFI to the architect or engineer of record.

The purpose is simple: get a clear, documented answer when something in the plans, specs, or contract documents is unclear, missing, or conflicting.

A construction RFI is not a casual phone call or a text to the architect. It is a formal document that becomes part of the project record. That matters because the response to an RFI can affect scope, cost, and schedule. You want it in writing.

Here is what a typical RFI includes:

• RFI number (sequential, unique to the project)
• Date submitted
• Project name and number
• The question, with references to specific drawing sheets, spec sections, or details
• Suggested solution (if you have one)
• Supporting photos or markups
• Date a response is needed by
• Who it is assigned to

The request for information construction process exists because plans are never perfect. Architects and engineers do their best, but conflicts between trades, missing details, and unclear dimensions happen on every project. RFIs are how you get those issues resolved before they turn into rework.

When to Submit a Construction RFI

Not every question needs a formal RFI. But if any of these situations come up, you should submit one:

Unclear Drawings

The plans show a wall but do not call out the material. Is it wood framing or metal stud? The detail does not match the plan view. A dimension is missing. These are all situations where you need a formal answer before you build.

Conflicting Specifications

The structural drawings call for one thing. The architectural drawings call for something different. Maybe the door schedule says 3-0 but the floor plan shows a 2-8 opening. When two documents disagree, an RFI gets you the right answer on record.

Missing Information

Sometimes the plans just do not cover a condition. There is no detail for how the roof meets the parapet. The electrical panel location is not shown. If you cannot figure it out from the documents you have, submit an RFI.

Unexpected Site Conditions

You start digging and hit rock that was not in the geotech report. The existing framing behind a demo wall is not what the plans assumed. Site conditions that differ from the documents need to be documented through the RFI process construction teams rely on.

Material Substitutions

The specified product is discontinued or has a 16-week lead time. You want to propose an alternative. An RFI is the right way to get approval for a substitution and keep it on the project record.

The rule of thumb: If the answer could affect cost, schedule, or quality, put it in an RFI. A five-minute question today can prevent a $50,000 mistake next month.

The RFI Process Step by Step

Here is how the RFI process construction teams follow works from start to finish:

Step 1: Identify the Issue

Someone on your team spots a problem. Maybe it is your superintendent reading the plans during layout. Maybe a sub calls you with a question. The first step is simply recognizing that you have an issue that needs a formal answer.

Do not wait. The sooner you submit, the sooner you get your answer. Sitting on a question because you are “not sure if it is worth an RFI” is one of the most common mistakes contractors make.

Step 2: Write the RFI

This is where most contractors either do well or fail. A good RFI gets answered quickly. A bad one gets bounced back with “please clarify” and you lose another week. We will cover how to write a good one in the next section.

Step 3: Submit the RFI

Send it through the proper channel. On most projects, RFIs go from the GC to the architect. Some projects use a web-based system where you upload the RFI directly. Others still use email. Whatever the method, make sure it is logged and time-stamped.

Step 4: Track It

Every RFI needs a number, a submission date, an assigned party, and a due date. You should be able to look at your RFI log at any time and see exactly which ones are open, which are overdue, and who is holding things up.

Step 5: Receive the Response

The architect or engineer reviews the question and sends back an answer. Sometimes the response is straightforward. Other times it requires a revised drawing or a new detail. Make sure the response is distributed to everyone who needs it, including your subs.

Step 6: Implement the Answer

Once you have the response, act on it. Update your plans, tell your crew, and adjust your schedule if needed. If the response changes the scope or adds cost, start a change order right away.

How to Write a Good Construction RFI

A vague RFI is a slow RFI. Here is how to write one that gets answered the first time.

Be Specific About the Problem

Bad: “The plans are unclear on the second floor.”

Good: “Sheet A2.1, Detail 4: The section shows the parapet cap as precast concrete, but the specification section 07 62 00 calls for sheet metal coping. Please confirm which material to use.”

The more specific you are, the faster the architect can answer. Reference exact drawing numbers, detail numbers, and spec sections.

Propose a Solution

Architects are busy. If you suggest a reasonable solution, they can often just approve it instead of having to research the issue from scratch.

Example: “We recommend using the sheet metal coping per the spec section, as it aligns with the waterproofing details shown on sheet A5.3. Please confirm or advise.”

This also shows you have thought about the issue, which builds trust with the design team.

Include Photos and Markups

A picture is worth a thousand words, especially in construction. If you are dealing with a field condition, take a photo. If the conflict is on the drawings, mark up the relevant sheets and attach them.

Projul’s photo and document management features make it easy to attach photos directly to project records so everything stays in one place.

Ask One Question Per RFI

Do not bundle five questions into one RFI. Each question should be its own RFI with its own number. This makes tracking easier and prevents situations where three of your five questions get answered but two do not.

Set a Clear Deadline

Tell them when you need the answer. “We need a response by March 20 to avoid a delay to the framing schedule” is much more effective than leaving the due date blank.

Reference the Impact

If a late response will delay the project, say so. “A response is needed within 5 business days. The drywall crew is scheduled to start on the 25th and cannot proceed until this is resolved.”

When the design team understands the schedule impact, they tend to respond faster.

RFI Response Times and What to Do When They Are Slow

Most construction contracts specify an RFI response time of 7 to 14 days. Some fast-track projects require 3 to 5 days. But in reality, response times vary widely.

Why RFIs Get Stuck

• The architect is overwhelmed with RFIs from multiple projects
• The question requires input from a structural engineer or other consultant
• The RFI was too vague and needs clarification
• It fell through the cracks in someone’s inbox

How to Speed Up Responses

Follow up early. Do not wait until the deadline passes. Send a polite reminder 2 to 3 days before the response is due.

Escalate when needed. If an RFI is overdue and it is holding up work, escalate to the owner’s representative or project manager. Be professional, but be direct about the schedule impact.

Batch your RFIs wisely. If you have several questions about the same drawing or system, submitting them around the same time helps the design team review them together.

Use your project communication tools. Projul’s communication features let you send reminders and keep conversations tied to specific project items, so nothing gets lost in a generic email thread.

Document everything. If a late RFI response causes a delay, you need a paper trail. Log the submission date, the due date, every follow-up, and the actual response date. This documentation protects you if there is a dispute about schedule delays later.

How RFIs Affect Your Schedule and Budget

RFIs are not just paperwork. They have real costs.

Schedule Impact

Every open RFI is a potential delay. If your crew cannot proceed until a question is answered, that is dead time. On a project with tight sequencing, one late RFI response can push back multiple trades.

A 2020 study by Navigant (now Guidehouse) found that the average cost of a single RFI on a commercial project is over $1,000 when you factor in the administrative time to write, submit, review, and respond. On large projects with hundreds of RFIs, that adds up to hundreds of thousands of dollars.

Budget Impact

Late RFI responses often lead to change orders. If you had to work around an unanswered question, you may need to tear out and redo work once the answer comes. That is rework cost that was not in your bid.

Slow RFIs can also cause material delays. If you cannot order a product until the architect confirms the specification, you may miss your procurement window and end up paying rush charges.

Protecting Yourself

The best defense is a good RFI tracking system combined with clear communication. When you can show exactly when you submitted an RFI, when it was due, and when you finally got a response, you have the documentation to back up a time extension or change order request.

Tracking RFIs So Nothing Gets Lost

A single lost RFI can cost you thousands. Here is how to make sure that does not happen.

Use an RFI Log

Every project should have an RFI log that tracks:

• RFI number
• Date submitted
• Subject or description
• Drawing or spec reference
• Who it was sent to
• Response due date
• Status (open, answered, overdue)
• Date the response was received

You can do this in a spreadsheet for a small project. But if you are running multiple jobs at the same time, a spreadsheet RFI log will eventually let something slip.

Why Software Beats Spreadsheets

Construction project management software like Projul gives you a central place to create, submit, and track RFIs alongside all your other project documents. Everyone on the team can see the status of every RFI in real time. No one has to ask “did we ever hear back on RFI 47?”

Key benefits of tracking RFIs in software:

• Automatic numbering so you never have duplicate RFI numbers
• Date stamps that cannot be edited after the fact
• Notifications when a response is due or overdue
• Attachments like photos, markups, and revised drawings stay with the RFI
• Search so you can find any RFI by keyword, number, or status
• Reporting so you can see response time trends and identify bottlenecks

Share Responses With Your Team

Getting the answer is only half the job. You also need to make sure the right people see it. When an RFI response comes in, distribute it to:

• The superintendent on site
• The affected subcontractors
• Your project manager
• Anyone else whose work is affected by the answer

Projul’s communication tools make it easy to share updates with the right people without relying on forwarded emails that someone might miss.

Construction RFI Template: What to Include

If you are building your own construction RFI template, make sure it includes these fields:

1. Project name and number
2. RFI number (sequential)
3. Date submitted
4. From (your company and contact)
5. To (architect, engineer, or owner)
6. Subject (brief description)
7. Question (detailed, with drawing and spec references)
8. Suggested answer (your proposed solution)
9. Attachments (photos, markups, related documents)
10. Response needed by (date)
11. Schedule impact (what happens if the response is late)
12. Response section (for the answering party to fill in)

A good template keeps everyone on the same page and makes sure no critical information gets left out.
