Which of the following is NOT a role of the registered design professional (RDP)?

• A. Conducting structural observations
• B. Hiring the contractor
• C. Approving special inspectors
• D. Consulting on project compliance

Answer: (B)

The role of the registered design professional (RDP) encompasses various responsibilities related to the design and oversight of construction projects. Hiring the contractor typically falls under the purview of the project owner or developer rather than the RDP. The RDP is generally focused on ensuring that the design adheres to relevant codes, standards, and regulations, as well as overseeing the implementation of the design during construction.

Conducting structural observations is a key duty of the RDP, providing assurance that the construction aligns with the design intent and meets the necessary structural integrity requirements. Approving special inspectors is also a critical responsibility as it ensures that necessary inspections are performed by qualified individuals to maintain compliance with construction standards. Additionally, consulting on project compliance pertains to the RDP's role in ensuring that all aspects of the project meet established codes and regulations during various phases of development.

In summary, while the RDP is involved in oversight and compliance regarding the design and construction processes, the actual hiring of the contractor is an activity typically outside their designated responsibilities.
