According to the Code of Standard Practice for Steel Buildings and Bridges, what types of corrections are permitted during steel framing erection?

During the steel framing erection process, the Code of Standard Practice for Steel Buildings and Bridges permits specific types of corrections to ensure that the structure aligns correctly and meets design specifications. The correct choice focuses on methods that can be used to adjust and fit pieces during assembly without significant alterations that could compromise the integrity of the structure.

Drift pins, grinding, and reaming are recognized methods for making adjustments to fit steel components. Drift pins are often used to align holes in structural steel members temporarily while bolting them in place, making it easier to achieve correct alignment. Grinding and reaming help in refining and enlarging holes to ensure that fasteners fit properly. These techniques enable erectors to adjust connections and achieve proper fitment without replacing entire components or making more substantial modifications that could affect the overall stability and design intent of the structure.

In contrast, the other options involve methods that either should not be performed during the erection phase without substantial justification or could lead to structural concerns. For instance, replacement of steel components during erection is generally not permitted, as it indicates a fundamental issue that could require extensive revisions to the design and structure. Similarly, while additional welding seams might sometimes be necessary, adding them outside of the specified design can weaken the integrity and safety of the
