In order for a project to complete the design certification stage requirements, the EDGE Client...

The design certification stage (Preliminary Certification) in EDGE requires specific actions from the Client to ensure the project can be audited and certified. The EDGE Certification Protocol outlines the process: "To complete the design certification stage, the EDGE Client must provide the EDGE Auditor with access to the completed self-assessment in the EDGE software, along with all supporting documentation, such as drawings, specifications, and calculations, to verify the selected measures" (EDGE Certification Protocol, Section 3.1: Certification Process). Option C, provide the EDGE Auditor access to the self-assessment and all supporting documentation, matches this requirement. Option A (internally review the EDGE measures) is a preparatory step, not a certification requirement: "Internal reviews are recommended but not mandated for certification" (EDGE User Guide, Section 6.1: Project Preparation). Option B (access the EDGE software and complete a self-assessment) is a prerequisite to the audit, not the final step for design certification: "The self-assessment must be completed before the audit, but certification requires submission to the Auditor" (EDGE Certification Protocol, Section 3.1: Certification Process). Option D (sign an agreement with a certification partner) is incorrect, as this is typically handled during project registration, not design certification: "Agreements with Certification Providers are signed prior to registration, not at the design stage" (EDGE Certification Protocol, Section 2.1: Registration). Thus, providing the Auditor access (Option C) is the required action.
