What is primarily inspected regarding steel in Special Inspections?

The focus of Special Inspections regarding steel primarily revolves around ensuring the integrity and performance of structural connections, particularly involving high-strength bolts. High-strength bolts are critical in steel construction as they are responsible for connecting different steel members and ensuring the structural stability and safety of the overall framework.

During Special Inspections, inspectors verify that the high-strength bolts used meet specified material standards and are installed correctly according to the design specifications. This includes checks for bolt dimensions, grades, coatings, and proper tightening methods (e.g., torque specifications). Ensuring that these components are accurately installed and comply with construction documents is essential for achieving the intended load-bearing capacities and performance under various conditions.

The other options, while they address important aspects of construction, do not represent the primary focus of inspections for steel in this context. For instance, the quality of concrete, inspection of electrical components, and the durability of steel finishes are relevant aspects but do not directly pertain to the special inspection requirements specifically associated with steel structures.
