Which document includes the required dimensional tolerances for structural steel?

The Code of Standard Practice for Steel Buildings and Bridges is the document that outlines the required dimensional tolerances for structural steel. This document serves as a guideline for the fabrication and erection of steel structures, providing industry-wide standards that help ensure safety, reliability, and consistency in construction practices. It specifically addresses tolerances related to dimensions, shapes, and other structural attributes, which are critical for the proper fit and performance of steel components.

Understanding how these tolerances apply is essential for any professional involved in steel construction, as deviations can affect the structural integrity and compatibility of the elements being assembled. The other options, while relevant to steel construction and engineering, do not focus specifically on dimensional tolerances to the same extent as the Code of Standard Practice.
