Non-conforming and corrective work can impact which certification level related to sustainability?

• A. ISO 9001:2015
• B. CCM
• C. LEED
• D. ISO 14001:2015

Answer: (C)

The concept here is how non-conforming and corrective work affects a sustainability certification that uses a levels-based scoring system. LEED assigns an overall level (Certified, Silver, Gold, Platinum) based on credits earned across categories such as energy, water, materials, and indoor environmental quality. When non-conforming work is identified, credits tied to those areas can be jeopardized or lost unless proper corrective actions are implemented and verified. Once the corrective actions are completed and re-evaluated, the project can recover or gain the necessary credits to reach or maintain a higher LEED level. This direct link between performance, verification, and a defined sustainability level is what makes LEED the correct choice.

ISO 9001:2015 focuses on quality management, CCM is a professional certification for construction management, and ISO 14001:2015 governs environmental management systems with non-conformance and corrective actions as part of the system, but it does not define a levels-based certification like LEED.
