What is RFI (Request for Information)?
A Request for Information (RFI) is a formal construction document which serves to request clarification, questions, and conflicting information regarding a project.
Definition
Purpose
The aim of an RFI is to remove uncertainty prior to affecting construction. If teams receive conflicting dimensions, missing details, or unclear specifications, an RFI will provide an opportunity to get it reviewed and resolved in an official communication process.
The other plus is that it enhances collaboration by providing an open record of project decisions. All requests and responses are recorded, so teams can track changes, maintain accountability for it all, and ensure everyone is working with the same information.
Examples of Use
- A contractor submits an RFI to confirm the correct dimensions after finding conflicting measurements on two drawing sheets.
- An electrical subcontractor raises an RFI in case the project plans don’t specify conduit routing information for a mechanical room.
- A site team sends an RFI to clarify the type of concrete finish required before placing an order with the supplier.
- A plumbing contractor files an RFI after discovering that existing site conditions differ from the information shown in the construction drawings.
Notes
- An RFI is meant to clarify existing project information, not request new design work or change the project scope.
- RFIs are typically submitted by contractors or subcontractors and answered by architects, engineers, consultants, or the project owner.
- Keeping RFIs clear, specific, and well-documented helps reduce misunderstandings and project delays.
- Timely responses to RFIs are important because unresolved questions can slow construction activities and affect project schedules.
