The correct answer is that a special inspector does not need basic knowledge of structural design. A special inspector's primary role is to ensure that the construction complies with the approved plans and specifications, as well as applicable codes and standards. This involves overseeing the inspection process, performing tests, and interpreting results, rather than engaging directly in the design of the structures.

Understanding the specifics of structural design is typically the responsibility of engineers or designers who create the plans, while special inspectors primarily monitor and verify compliance with those plans. They must have a solid grasp of plan reading to interpret construction documents, as well as knowledge of how to perform required tests to validate materials and workmanship. Familiarity with code provisions is crucial for determining compliance with local, state, and national regulations that govern construction practices. In contrast, being skilled in structural design itself is not a prerequisite for effectively conducting inspections or ensuring that the work meets its standards.
