What must utility maps be?

• A. Utility maps should be updated only when requested by the project manager.
• B. Maps are optional and can be ignored if not available.
• C. Utility maps must be kept current and accurate.
• D. Maps should be kept secret and not shared.

Answer: (C)

Keeping utility maps current and accurate is essential because these maps guide where to locate and mark underground facilities before digging. When maps reflect the real, up-to-date locations of utilities, crews can plan safely, avoid strikes, and coordinate with other work. Updates are necessary anytime there are changes in the subsurface—new installations, relocations, or discrepancies found during locates—so that the information used in the field matches what’s actually there. Relying on outdated or wrong maps increases the risk of hitting a line, causing outages or injuries, and can lead to costly delays and regulatory issues. Sharing and maintaining accurate maps ensures everyone on the project has the correct information, rather than keeping it hidden or treating it as optional.
