Why are as-built drawings important during a PFSP or security-focused facility review?

• A. They verify actual layouts, access controls, and placement of barriers and critical assets.
• B. They show historical weather data.
• C. They provide budget details.
• D. They serve as marketing materials.

Answer: (A)

As-built drawings provide an accurate snapshot of the facility as it actually exists, which is essential for security assessments. In a PFSP or security-focused facility review, you need to verify that the real layout matches what the security plan assumes: where entry points and access controls are located, how barriers are placed to restrict movement, and where critical assets sit. These drawings reveal true conditions—such as relocated doors, added or removed barriers, or camera and sensor placements—that can significantly affect security effectiveness. By comparing the drawings to the current site, you can identify gaps, ensure protective measures are properly aligned with actual layouts, and plan appropriate upgrades or responses. Without up-to-date as-built drawings, vulnerabilities can go unnoticed, response routes may be misplanned, and the overall security posture can be misrepresented. Historical weather data, budget details, or marketing materials don’t provide the accurate map of where security controls and assets actually are, so they aren’t useful for this purpose.
