Which document is used to clarify a project design issue?

A Request for Information (RFI) is a document used to clarify project design issues. RFIs are typically issued when there is a need for additional information or clarification on specific aspects of the project design. This helps ensure that all parties have a clear understanding of the requirements and can proceed with accurate and consistent implementation. RFIs are commonly used in construction and AV projects to address uncertainties or discrepancies in the design documents.
