What is the required inspection level for structural soundness of a newly built frame?

• A. Visual inspection only
• B. Load testing during construction
• C. Full structural plan review and inspection
• D. Random sampling of materials

Answer: (C)

The required inspection level for the structural soundness of a newly built frame is full structural plan review and inspection. This comprehensive approach ensures that all aspects of the building's structural integrity are accounted for, as prescribed by the North Carolina Building Code.

A full structural plan review involves a detailed examination of the design documents, calculations, and specifications to verify that they comply with relevant codes and standards. This step is crucial to identify any potential issues before construction begins, ensuring that the building is designed to safely support loads and resist environmental factors.

Following the review, inspections during construction allow for ongoing assessment of the work. Inspectors check whether the construction complies with the approved plans and specifications, which helps to ensure that all materials and methods used contribute to the overall structural integrity of the frame. This twofold verification—first through review and then through physical inspection—guards against common construction errors and ensures that safety standards are met throughout the building process.

Visual inspection only, load testing during construction, and random sampling of materials do not provide the same level of thoroughness and assurance. Visual inspections are limited in their ability to detect hidden defects or non-compliance with design specifications. Load testing, while useful in certain scenarios, does not replace the need for planning and extensive inspections.
