RFI in Construction: Meaning, Process & Best Practices

An RFI (Request for Information) in construction is a formal, written request used to clarify unclear, missing, or conflicting information in the contract documents: drawings, specifications, or scope of work. Any project stakeholder can issue one, but general contractors submit the majority of RFIs, most often to the architect or engineer of record. 

An RFI is one of several "RFX" documents used throughout a construction project, alongside the Request for Proposal (RFP) and Request for Quotation/Qualifications (RFQ).

While RFPs and RFQs are mostly used during procurement and bidding, RFIs are used throughout the entire project, before a contract is awarded, during bidding, and continuously through construction until closeout. 

Understanding how to write, submit, and respond to an RFI can help general contractors avoid delays, protect against disputes, and keep a project on schedule and on budget. 

Key Takeaways 

• An RFI is a formal clarification request, not a casual question; it becomes part of the permanent project record.
• The most common industry-standard form is AIA Document G716, though many project management platforms include their own templates.
• A well-written RFI asks one clear question, references specific drawings or spec sections, and, when possible, suggests a solution.
• RFIs are expensive when mismanaged. Research from the Navigant Construction Forum found the average RFI takes roughly 10 days to resolve, costs about $1,080 in administrative and technical review time, and nearly 22% are never answered at all. 

What to Include in a Construction RFI?

RFI templates are available from multiple sources, and many are built directly into construction project management software. Whatever format is used, most contracts reference the AIA Document G716, the industry-standard RFI form.

Regardless of the source, a solid RFI should include:

• Project name, number, and address
• RFI number for tracking (numbered sequentially: 001, 002, 003)
• Unique RFI title
• Submittal date and requested response deadline
• Name, title, company, and contact information for the initiating party
• A clear description of the request, referencing specific drawing sheets or spec sections
• Any supporting attachments: photos, sketches, or marked-up drawings
• A suggested solution, if one exists
• The potential cost or schedule impact if the answer is delayed
• Name, title, company, and contact information for the responding party

A standardized form or template reduces the back-and-forth needed to prepare and respond to an RFI, and it gives both parties a consistent structure to work from. 

When to Use an RFI

Once a contract is in place, RFIs are used to resolve ambiguities, capture decisions, and fill information gaps in the drawings, specifications, or project documents. Common triggers fall into four general categories:

• Design and specification gaps: Unclear or conflicting drawings, missing details, or errors and omissions that need to be corrected before work can proceed.
• Coordination and scheduling: Establishing communication between stakeholders, or adjusting task sequences due to material or labor constraints, often as part of lean construction workflows that depend on tight sequencing.
• Site and constructibility issues: Unsafe or unfeasible site conditions, existing utility conflicts, or proposed materials that don't work as specified in the field.
• Scope and method changes: Requesting a different construction method, altering scope, swapping materials, or proposing a value-engineering change.

RFIs are the accepted way to communicate changes to the original contract or plan to every stakeholder, and to request guidance or acceptance before proceeding. Understanding what belongs in an RFI, and what doesn't, helps move a project forward with less rework and fewer costly delays. 

Best Practices for Using an RFI in Construction

RFIs should resolve the inevitable questions that come up on any construction project. They shouldn't be used to generate conflict over contract language or issues unrelated to completing the work. The following practices make the RFI process faster and more effective for everyone involved. 

Build a Documented RFI Process

RFI tracking keeps the process transparent and keeps every party informed. Whether the log is manual or electronic, every RFI should get a sequential number, and the tracking system should show where each request stands.

At a minimum, an RFI process should:

• Explain how to request a tracking number
• Identify who is responsible for tracking RFIs
• Stipulate response times
• Define what qualifies as an RFI (versus a change order or submittal)
• Provide a standard RFI template
• Establish what supporting documentation is required

Each stakeholder should maintain their own internal process for tracking RFIs to ensure timely responses.

Ask One Clear Question per RFI

RFIs are often hard to follow because they lack context or bundle multiple issues together. Unclear language leads directly to confusion and delayed answers.

That's why an effective RFI asks a single, specific question.

For example: a contractor needs to adjust the work schedule because of a material delivery delay. Rather than a vague complaint, the RFI should ask something specific: "Can Material X be used in place of Material Y to avoid the delay?" The reasoning behind the request belongs in the description field, not the question itself. 

Provide Options Whenever Possible

When a request includes a proposed solution, the recipient only has to approve or decline, which speeds up the response significantly.

For example, instead of just flagging a conflict, an RFI might ask: "Is it possible to move the parking garage entrance 15 feet north to accommodate an existing water line?"

The description can explain why the change is necessary and list supporting documentation. 

The architect or engineer can approve the request or propose an alternative. Either way, the RFI keeps the project moving instead of stalling on an open-ended problem. 

Respond to RFIs Promptly

Most RFIs flow from contractors to the design team, but engineers and architects submit them too. Every RFI received should be logged by number and question immediately, using the same internal tracking process.

Responses should always address the cost and schedule impact of each proposed option, since these figures often need to be reflected in the project's schedule of values line items. A request to relocate an interior wall, for instance, should note what's required to execute the change, and if an alternative exists, that option should be included with its impact clearly stated.

The goal of the RFI process is a clear communication channel that minimizes errors and rework. Misuse of the process creates friction and delays instead, so addressing these best practices proactively leads to smoother working relationships across the project team. 

Common RFI Challenges (and How to Avoid Them) 

Used correctly, the RFI process keeps a project moving. Used carelessly, without training or a documented procedure, it generates unnecessary requests, friction between stakeholders, and avoidable delays.

Review the Contract Before You Submit

Before creating an RFI, review the contract and supporting documents first. Simple clarifications can often be handled through other communication channels, which keeps the RFI process reserved for genuine information gaps.

RFIs are time-consuming and expensive: research from the Navigant Construction Forum found the average RFI cycle costs around $1,080 and takes close to ten days to close out, and more than one in five go unanswered entirely. A documented process that clarifies when an RFI is actually warranted saves everyone time and money.

Catch Issues Early During the Bidding Phase

Contractors can head off many of these challenges by understanding the construction bidding process before the contract is even awarded. During bidding, contractors review plans, specifications, and terms, and if anything is unclear, they can issue an RFI to the project owner or architect before submitting a bid.

This helps prevent pricing errors and misunderstandings that are far more expensive to fix later. The same applies to equipment costs: contractors who know how to write a rental quote can avoid similar pricing surprises during bidding.

After the contract is awarded, RFIs continue to be the tool for resolving new questions and discrepancies as they surface. Any resulting changes to the original plans and specifications should be documented and approved by all relevant stakeholders. This record is essential for quality control, since it shows exactly what was agreed to and confirms every change was implemented correctly.

Understanding the full RFI, RFP, and RFQ process, and staying proactive about it, helps general contractors reduce disputes and improve their track record for winning future work. 

RFI vs. RFP vs. RFQ: What's the Difference?

"RFI," "RFP," and "RFQ" all start with "Request For," which is part of why some people get confused, but each serves a distinct role in the procurement and construction process. 

RFIs

RFIs may be used before, during, or after an RFP is issued. Before an RFP is released, they're often used to gather information about potential suppliers, questions about a company's experience, licensing, or safety record.

For example, an RFI issued before an RFP might ask:

• Does your company have experience building on a floodplain?
• How many licensed heavy equipment operators does your company have?
• How many multi-year construction contracts has your company completed?
• Does your company have a written safety plan?

Companies use this input to prepare an RFP or to identify a pool of qualified suppliers to receive one. 

RFPs

A request for proposal (RFP) begins the formal procurement process.

The RFP defines the project, its goals, and the organization overseeing the contract. It sets a submission deadline and an award date, and in most cases lists the evaluation criteria and how the award will be managed. Depending on scope and size, the RFP process can take months to complete.

Once an RFP is issued, any questions or clarifications must be submitted in writing. Some organizations define a specific process for this in the RFP itself; others rely on the standard RFI process instead. 

RFQs

The group issuing the RFP may use an RFQ to request a bidder's financial and safety records, licensing documentation, or employee information; this is a request for qualifications.

Alternatively, RFQs can be requests for a quotation, often referred to as "asking for pricing." These may be issued to a subset of bidders at the end of an RFP review, or used to solicit pricing for standardized goods or services.

FAQs

Who is responsible for submitting and responding to a construction RFI?

Any project stakeholder can submit an RFI, but general contractors and subcontractors submit the majority. Most RFIs are routed to the architect or engineer of record for a response.

How long does it take to get a construction RFI answered?

Research from the Navigant Construction Forum found the average RFI takes close to 10 days to resolve, though timelines vary depending on the contract's specified response window and the complexity of the question.

Does an RFI response authorize a contractor to proceed with extra cost or time?

No. A standard RFI response, including the AIA G716 form, explicitly states that it does not authorize additional cost or time. If a clarification changes scope, cost, or schedule, it must be followed by a formal change order.

What is the AIA G716 form?

AIA Document G716 is the construction industry's standard RFI form, used by owners, architects, and contractors to formally request clarification during a project. It creates a documented paper trail that can protect all parties if a dispute arises later.

How many RFIs does a typical construction project generate?

This varies widely by project size and complexity, but larger projects can generate hundreds of RFIs before completion, which is why a documented tracking process is essential.
