What should be included in as-built drawings after work is completed?

• A. The original schematic diagram only.
• B. A copy of the original contract terms.
• C. Documentation showing final installed configuration and locations after work.
• D. Customer's personal contact information.

Answer: (C)

As-built drawings capture the system exactly as it was installed, showing the final configuration and the precise locations of equipment, devices, wiring routes, and terminations. This record reflects any field changes or deviations from the original plan, so maintenance, service, and future upgrades can be performed accurately. It also supports code compliance and inspections by providing a truthful map of what exists in the building.

The other options don’t fit as installation documentation: the original schematic may no longer match the actual wiring if changes were made, contract terms aren’t part of the physical installation record, and a client’s personal contact information isn’t relevant to the installed configuration and could raise privacy issues.
