According to the Specification for Structural Steel Buildings, what identifies each primary structural steel member?

The identification of each primary structural steel member is the responsibility of the fabricator, who ensures that each piece of steel is marked according to the specifications and drawings provided for the project. The fabricator is tasked with not only crafting the steel members but also tagging or labeling them appropriately for identification during construction and erection. This process is essential for maintaining quality control, ensuring proper assembly on-site, and facilitating inspections.

While the site engineer, lead inspector, and construction manager all play significant roles in the construction process, their responsibilities are more oriented toward oversight, inspection, and project management rather than the actual fabrication and identification of steel members. The fabricator's role is critical as they are directly involved with the materials, and this specific task falls within their expertise.
