Who must acknowledge awareness of special construction and inspection requirements for a seismic force resisting system?

The correct answer is that the registered design professional must acknowledge awareness of special construction and inspection requirements for a seismic force resisting system. This individual is usually a licensed architect or engineer who is responsible for the overall design of the structure, ensuring that it meets not only the aesthetic and functional needs but also the safety and performance criteria established by building codes.

In the context of seismic design, the registered design professional has a critical role in understanding and documenting the specific requirements necessary to ensure the safety and integrity of the structure during seismic events. Their acknowledgment is essential because they are intimately involved in the design process and must ensure that the construction aligns with the planned seismic force resisting system. This knowledge is crucial to inform contractors, inspectors, and other stakeholders about the expectations and requirements laid out during the design phase, which contributes to the overall effectiveness of the project in resisting seismic forces.

The other roles mentioned, such as the contractor, special inspector, and seismic engineer, certainly play vital roles in the overall process, but the direct responsibility for acknowledging and understanding the design intent related to seismic design falls on the registered design professional. Their awareness ensures that all parties involved are aligned in executing the approved plans, thereby enhancing the safety and performance of the structure during seismic activities.
