The NCIDQ IDPX exam tests the designer’s understanding of project closeout and documentation retention. Retaining the correct documents is critical for legal, professional, and future reference purposes.

Option A (Record (as-built) drawings and specifications):This is the correct choice. Record (as-built) drawings reflect the final constructed conditions, including any changes made during construction, and specifications document the materials and methods used. These are essential for the designer’s records, as they provide a complete and accurate record of the project for future reference, liability protection, and potential use in similar projects.

Option B (Post-occupancy evaluation and specifications):A post-occupancy evaluation (POE) is useful for assessing the project’s performance, but it is not a standard document retained for legal or reference purposes in the same way as as-built drawings. Specifications are important, but without the as-built drawings, this option is incomplete.

Option C (Record (as-built) drawings and inspection report):Inspection reports (e.g., from code officials) are typically retained by the contractor or owner, not the designer, unless specified in the contract. While as-built drawings are critical, the inspection report is not a standard document for the designer’s files.

Option D (Post-occupancy evaluation and inspection report):Neither the POE nor the inspection report are core documents for the designer’s project files. They may be retained if relevant, but they do not provide the comprehensive record needed for future reference like as-built drawings and specifications.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on project closeout and documentation.

“Upon project completion, the designer should retain record (as-built) drawings and specifications in their files to document the final design and construction for future reference and liability protection.” (NCIDQ IDPX Study Guide, Project Closeout Section)

The NCIDQ IDPX Study Guide specifies that record (as-built) drawings and specifications are the primary documents the designer should retain at project completion. These documents provide a complete record of the project, ensuring the designer has accurate information for future use or legal purposes, making Option A the correct choice.

Objectives:

Understand documentation requirements for project closeout (NCIDQ IDPX Objective: Project Closeout).
