What types of openings for other trades can be cut in structural steel according to the Code of Standard Practice?

Openings for other trades in structural steel should be made in accordance with the specifications outlined in the contract documents. This ensures that any modifications or alterations follow pre-approved plans, thereby maintaining the structural integrity and compliance with safety regulations. The contract documents typically define the size, location, and purpose of the openings necessary for mechanical, electrical, plumbing, or other systems, and they ensure that the necessary considerations have been made regarding load distribution and structural performance.

In contrast, options related to contractor discretion or future modifications do not align with the strict guidelines of the Code of Standard Practice. Allowing any openings required by contractors could lead to unauthorized alterations that might compromise the structure's integrity. Openings made solely for fire safety measures, while important, usually fall under specific codes and guidelines that need to be referenced separately from standard practice. Additionally, adjustable openings for future modifications do not usually conform to specific structural requirements unless explicitly stated in the contract documents. Thus, adhering to the predetermined guidelines in the contract is crucial for safety and structural soundness.
