Plans submitted for review often include additional documents known as what?

The term "supporting documents" encompasses a broad range of materials that accompany the primary plans submitted for review. These documents serve to provide additional context, clarification, or justification for the proposed designs and ensure compliance with relevant codes, regulations, and standards.

Supporting documents can include calculations, manufacturer's specifications, risk assessments, or any other information that helps demonstrate how the project meets the necessary requirements. By including such documents, the submitter aids reviewers in their evaluation process, thereby facilitating smoother and more thorough inspections.

In contrast, terms like specifications or architectural reports, while relevant, specifically refer to particular types of documentation rather than the all-encompassing term that "supporting documents" represents. Therefore, "supporting documents" is the most appropriate choice in this context, as it accurately reflects the variety of materials that may accompany the main plans during the review process.
