Who performs structural observations?

Structural observations are typically performed by a Registered Design Professional (RDP). RDPs are licensed engineers or architects who have the qualifications and expertise to assess the design and functionality of structural systems. Their role involves ensuring that the structure is built according to the approved plans and specifications, which is crucial for maintaining safety and compliance with building codes.

The involvement of an RDP also implies a level of accountability and professional judgment that is necessary when evaluating the integrity of a building's design during construction. This assessment includes examining aspects like load paths, material use, and adherence to engineering principles.

The other roles, while important in the construction process, do not fulfill the specific requirements for structural observations. Special inspectors focus on specific construction details and materials for compliance with codes. Building inspectors generally inspect for overall compliance with building codes, but not solely from a structural engineering perspective. Contractor quality control involves ensuring that the contractor's work meets quality standards but does not typically involve formal structural observations by a qualified professional.
