The goal of an RFI (Request for Information) in construction is to fill in information gaps, reduce ambiguities, and document and discuss particular decisions made during the project. A general contractor or subcontractor often submits an RFI in written form to obtain information from a design, engineering, or construction professional. An RFI's information isn't included in the construction contract. Shop drawings, material data, samples, and product data are examples of submittals in construction management. The architect and engineer primarily use submittals to ensure that the correct items are used on the project. This method also allows the architect and sub-consultants to choose colors, patterns, and materials that were not decided before the building drawings were completed.
