Which assembly requires special inspections for compliance with construction documents?

Certain assemblies in construction are mandated to undergo special inspections to ensure that they adhere to the construction documents and relevant codes. Special inspections are particularly crucial for assemblies that could significantly impact the structural integrity and safety of a building.

Steel joint frame details require special inspections primarily due to the complexity and potential risks associated with steel construction. These details can involve connections and welds that are critical to the overall stability and strength of the structure. Inspectors are typically required to evaluate these steel connections meticulously, ensuring they are fabricated and installed according to the specified design and applicable building regulations.

Other categories like electrical systems, roofing materials, and interior finishes do not generally warrant the same level of scrutiny through special inspections. While these components are essential for the functionality and comfort of a building, the risks they present in terms of structural failure or safety issues do not necessitate the rigorous oversight that steel joint frame details require. Thus, the correct answer highlights the unique importance of steel construction details and the need for stringent compliance checks in that area.
