A request for information (RFI) is a document that is used by architects, engineers, general contractors, or subcontractors to ask specific questions about the design, materials, and other essential aspects of a particular construction project.

The purpose of an RFI is to provide information that can be used to make decisions or resolve issues related to the project. An RFI typically contains detailed descriptions of the needed materials and services along with specific instructions about how the required items should be delivered.

The recipient of an RFI is sought to provide detailed responses so that any potential misunderstandings between parties can be clarified before further work takes place on the construction project. An RFI is also often used to request cost estimates from vendors so that budgets can be determined before work begins on the residential construction project.
