What should happen if an inspector has begun performing functions in respect of the construction?

The correct choice highlights that the original appointment of the inspector remains valid, even if they have begun performing their functions regarding the construction project. This understanding is rooted in the principle that an inspector's authority to conduct inspections and enforce compliance does not cease simply because they have started their duties. The role of an inspector is essential for ensuring that the construction adheres to applicable codes and regulations, and their initial functions signify that they are actively overseeing the project to maintain safety and compliance standards.

In construction law, continuity and clarity are vital, and there are established protocols that allow inspectors to fulfill their designated roles unless formally revoked or invalidated under specific circumstances. Hence, the framework governing construction practices supports the idea that once appointed, the inspector's authority stands firm throughout the inspection process unless there is a legitimate reason to annul their appointment.
