RFI in construction is a process that multiple teams in a construction project use to get missing information and clarify design ambiguities and conflicts. They send it to the client or the subcontractor, from whom they get a written answer to the query raised. This answer becomes part of the project record, so every team works from the same information.
Construction RFIs, or requests for information, are documents or forms that mention the required information gaps. Every company has its own type of request for information RFI form or RFI template, where it may prioritize the deliverables they work with most.
Since construction work on the site depends upon drawings that were created before the work, RFI becomes the process to address any hiccups. This blog will explain what RFIs are, the difference between RFIs and submittals, and how BIM coordination reduces RFIs in a project.
Along with the RFI, there are two more documents that professionals use in the construction industry for client communication on technical matters. These are submittals and change orders, and they remain throughout the project. These are also documents related to the execution of on-site activities.
In simple words, the response to an RFI gives clarity to teams on whether there is anything missing in the construction documents. Contractors request a change order if the RFI response provides any new or corrected information. One critical consideration while handling RFIs is to keep them separate from change orders and submittals. The reason is that, later in the project, these records support or defeat a change order.
On a construction site, teams have multiple drawings for specific areas. When anything in them does not have complete information about a certain specification or a missing dimension, an RFI is raised.
Even after seamless BIM coordination and quality checks, some details can remain missing. For example, the connection between a wall and floor may be missing. Or, specifications for a certain product may only have its name without the size or finish type mentioned. In this case, the construction crews have to delay the installation or, if under pressure, might do the work by guessing. This usually leads to rework, project delays, and additional costs.
A large-scale commercial project has its work divided among many subcontractor construction firms. The parties involved specialize in a particular discipline, such as architecture, structure, or MEP. Even after BIM coordination, drawings developed by different people often do not match. For example, a beam might block a duct route, or a schedule plan may not align with the sequencing of structural work.
While the shop drawings come from a coordinated model, there can still be site conditions that the plan does not address. These can be soil conditions or the framing of an older building that has been missed during site inspection. In such conditions, subcontractors raise RFIs to get formal guidance that suggests a way to move forward.
Certain construction materials proposed in the design stage might not be available during construction. So, at that time, the solution is that subcontractors offer alternatives. They do this by raising an RFI to the design team, which they must evaluate and approve, to ensure continued progress. This is the kind of RFI that leads to a change order.
These are common situations where professionals raise RFIs to avoid rework and progress construction with certainty.
Construction projects in the US that are fairly large in scale quite struggle with the existing RFI workflow. It moves through several handoffs before the person who can actually provide the information gets it. The chain of handoffs in between adds extra time, which affects construction progress, thereby breaking the schedule.
Here is the typical path that is followed:
Gap identification: On the construction site, a foreman or a project engineer finds a missing piece of information in the given construction project plans without which the work cannot continue. At this stage, the RFI is with the subcontractor who identifies the conflict. They also do a thorough check on other construction documents at their end before passing it to the general contractors.
Send it to the general contractor: If there are multiple GCs in a super-large-scale project, subcontractors need to identify the appropriate one. If the RFI is complex or it is regarding coordination issue, a meeting is also held. Construction Coordination RFIs cover requests for scheduling and safety items. This helps the GCs have a clear understanding before they forward it to the design team.
Review and log it: The GC further checks the RFI for any duplicate queries and how accurate it is, which is a fundamental process. For the designers to give the answers correctly, they also add context and additional details to specific queries. And this is critical since the designers are unaware of the site conditions; it’s better to say they have not visited it even once. A number is also assigned for tracking, with a clear title and reference to relevant drawings.
Route it to the design team: At this stage, the architect, engineer, or contract administrator passes the question to the responsible consultant. For example, if the question is about framing, it goes to the structural engineer.
Involve the owner if needed: If the response to the RFI comes with, for example, an addition of material or a design change that needs coordination, project owners have to be involved. Such type of changes affect the cost, project timeline and project conditions. Here, the owner does not approve the answer, but their involvement, along with other project stakeholders, is required to approve the changes in the contract.
Close or escalate: If it concerns missing information, the RFI closes upon receipt. In cases where extra work is required, the contractor needs to escalate the matter to the key stakeholders.
The way an RFI is written or formed also defines how fast and accurate the answer is. Because design teams usually do not visit the site. So, they only have the information present in the RFI to interpret the situation that site teams are facing. Hence, a faster and useful response from them completely depends on how well and clearly the RFI is written. Here are the steps to make a difference in writing RFIs considering a project’s details:
Ask one question per RFI: The approach of bundling multiple questions and all the relevant information during RFI submission often leads design teams to spend more time evaluating each question, rather than providing quick answers. Even if there are multiple issues from the same area, there should be separate RFIs.
Reference the exact documents: In case of incomplete plans, the best practice is to refer to the exact document for the ease of designers and keeping them on the same page. For this, you have to cite the drawing number and revision, the specification section, and the location on-site.
Propose a solution: Suggesting alternative possible solutions can also speed up the process. For example, if it is about information, suggest specific project details you want to be present in the drawings. In the case of construction products and materials, a proposed alternative helps the designer approve it, correct it, or request clarification. Hence, they do not need to write information or solutions from scratch, which speeds up the response.
Set a response date: In the construction RFI process, a response date shows the design team the criticality of the RFI document. The best practice is to state a date aligning with the project timelines, with the reason mentioned; for example, the particular construction activities waiting for it. Another benefit of setting a response date is that the team can understand and set priorities when handling multiple RFIs.
The four habits above will help construction teams develop a structured RFI process. However, the meaning of an RFI coming up simply means there is going to be some delay in the construction process. So, the bigger question should be: how can we reduce the number of RFIs in a construction project? For that, we need to understand the reason behind RFIs in construction.
Coordination gaps occur in the design stage where multiple disciplines work together on a federated model. This is the stage where things go wrong; while most of them are fixed, some go completely unnoticed until they reach the site. According to The ninth annual CRUX Insight Report, which analyzed 2,410 projects across 122 countries, 40.5% of projects faced disputes due to design-related problems. In that, design errors were the most common, at about 20.8%, followed by late design information 19.7%) and incomplete designs 17.2%.
So these issues start when the construction plans from different disciplines are combined into one federated model. This is the model upon which every team collaborates to resolve the conflicts between their trades. BIM coordination improves this process throughout the project’s life cycle, but it can still leave room for RFIs. Usually, teams check everything before generating the construction blueprints or drawing sheets. The areas they often miss are differences in the level of detail, specifications that conflict with the model, or last-minute design changes not reflected in the drawings.
The coordination process works through these two tools:
Clash detection: Veteran companies in the industry usually use a software solution such as Navisworks. It compares the coordinated models and flags conflicts automatically. Coordination teams then review the clashes to come up with a solution in a timely manner. This resolution is also recorded to track back and gain clarity if there are issues in the future. Construction projects can typically generate many RFIs as the project size grows.
Model review: Project managers select a dedicated person called the model reviewer to check for elements that remained unflagged in the previous stage. These can be an unlabeled shaft, equipment blocking the door swing, or a structural opening not matching the beam dimensions.
RFIs cannot be avoided completely in a construction project even after BIM coordination and model reviews. If it were possible, we would not have to deal with it in the current times, where construction software and technology have become so advanced. So, the best practice is to track responses duly to avoid delays.
The simplest way teams can do this is to create an RFI log to track every request, the response, the target time, and the time required. It will show project participants the open requests that can pause construction and closed requests at a glance to point out where the time is being spent. Many construction firms also use construction management software to track RFIs along with other project aspects.
On the site, the person who has knowledge of the overall project should create the RFI log. It should include the following details: RFI number, the date raised, who holds it, the response due date, and the current status. Proper RFI management enhances accountability among project stakeholders.
However, creating a log is not enough unless a professional regularly reviews it. Here, the construction professionals will organize the open items in an order prioritizing their due date. This will help them clearly understand which RFIs are aging and need a push.
RFI in construction are part of the project, and dealing with them in a strategic manner is the key to avoiding delays. The most beneficial habit a construction professional can learn is to segregate each question and track RFIs until answered. On the other hand, effective BIM coordination will also help reduce the RFIs by resolving issues before they reach the site.

The response time of an RFI is already set in the contract documents. However, some contractors also set a default period based on a specific type of RFI.
In case an RFI remains unanswered, the first step is to check the log and find out who holds it. Then the simple process is to follow up with the designer, copying the general contractor or project manager.
RFIs do not change the construction contract price directly, but they can influence a change order, which can. RFI answers reveal missing information in drawings or an incomplete product/material specification. If that adds to cost, the contractor should submit the change order to the owner for approval of the pricing details.
