When a project specifies the use of a code, what is true about the requirements of that code?

When a project specifies the use of a code, it establishes that the requirements outlined in that code are mandatory. This means that all parties involved in the project, including designers, fabricators, and inspectors, must adhere to the specifications and guidelines provided in the code to ensure safety, structural integrity, and compliance with legal standards.

For instance, the Structural Welding Code – Steel (D1.1) provides comprehensive standards for welding practices, materials, and design criteria that must be followed. Compliance is not optional; rather, it is a requirement that helps to ensure that the welding work performed meets the necessary quality and safety standards expected in construction and fabrication.

Mandatory codes arise from the need to codify best practices and to protect public safety. They are developed through extensive research and consensus within the industry to reflect the current understanding of engineering principles and safety measures. When a code is specified, it serves as a legal and technical baseline that contractors and engineers must follow to avoid liability and enhance the reliability of the structure being built.
