For how long should a firm retain the as-built plans?

• A. Five Years
• B. Ten Years
• C. Until The System Is Decommissioned
• D. For The Life Of The Sprinkler System

Answer: (D)

The key idea is that as-built plans should be kept for the entire life of the sprinkler system. These drawings show the exact layout of piping, valve locations, head placements, and all components as they were actually installed. This up-to-date reference is essential for ongoing maintenance, troubleshooting, future retrofits or upgrades, and inspections. When changes are made to the system, the as-built should be updated so the documentation always matches the real installation. Keeping the plans only for a fixed period (five or ten years) risks losing critical information needed long after that window, and storing them only until decommissioning can leave gaps if work or investigations occur after decommissioning. So, the best practice is to retain the as-built plans for the life of the sprinkler system.
