What should be included in an as-built package from Cx?

• A. Updated equipment lists and revised drawings only.
• B. Updated sequences of operation, equipment lists, wiring diagrams, control settings, and revised drawings.
• C. Marketing summaries.
• D. Warranty terms.

Answer: (B)

The key idea is that the as-built package must capture exactly what is installed and how it operates, including the control logic and the concrete documentation that supports ongoing operation and future modifications. This means updating the sequences of operation to reflect the actual control behavior, listing every piece of equipment present, including wiring diagrams that show all connections, recording the final control settings and setpoints, and providing revised drawings that reflect any field changes. Together, these elements give the facility team a precise, usable reference for operating, maintaining, troubleshooting, and modifying the system in the future.

Marketing summaries aren’t about the installed system’s operation or maintenance, and warranty terms are separate contract documents, so they don’t belong in the technical as-built package. Equipment lists and revised drawings alone miss the critical control logic and settings that define how the system behaves, so they don’t fully support operations or future changes.
