Who holds the ultimate responsibility for the special inspections program?

The correct choice emphasizes the role of the Registered Design Professional (RDP) in responsible charge as the ultimate authority for the special inspections program. The RDP is typically a licensed professional, such as an architect or engineer, who is responsible for ensuring that the design is executed according to the approved plans and complies with applicable codes and regulations.

In this context, the RDP has overarching responsibility not only for the design aspect but also for coordinating the special inspections. This includes selecting qualified inspectors, overseeing the inspection process, and confirming that any deficiencies are addressed promptly. The RDP plays a critical role in safeguarding compliance and ensuring the integrity of the project's construction quality.

While other roles, such as the special inspector, building official, and contractor, have important functions within the special inspections program, they do not hold the ultimate accountability. The special inspector conducts the inspections and reports findings, the building official enforces building codes, and the contractor executes the construction activities; however, none of these roles entails the comprehensive oversight and responsibility that the RDP holds in the context of the special inspections program.
