Who is responsible for conducting structural observations?

The responsibility for conducting structural observations typically falls to the registered design professional. This is because registered design professionals, such as architects or engineers, have the expertise and authority to assess the structural integrity of a building or structure in accordance with the relevant codes and standards. Their training equips them to make informed decisions about the safety and reliability of structural elements throughout the construction process.

In contrast, other options do not accurately capture the role of structural observations. For example, while special inspections pertain broadly to various aspects of construction, they involve more than just structural components and are not synonymous with the observations performed by design professionals. Furthermore, structural components themselves can be inspected through special inspections, but that designation doesn't specify who conducts the observations. The term "random basis" implies a lack of systematic assessment, which contradicts the structured approach that a registered design professional brings to the process of conducting structural observations. Therefore, the registered design professional's role is critical in maintaining oversight and ensuring compliance with safety standards throughout the construction phase.
