When conflicting materials are specified in different sections of the IBC, what should be done?

When conflicting materials are specified in different sections of the International Building Code (IBC), the most appropriate course of action is to use the most restrictive guidance. This approach is based on the principle that safety and structural integrity are of the utmost importance in construction. The most restrictive guidance ensures that the highest standard of safety and performance is maintained, reducing potential risks associated with the use of materials that may not meet the necessary codes or regulations.

Employing the most restrictive guidance also helps to ensure compliance with local building regulations and may prevent future issues related to liability or structural failures. In contexts where the code does not clearly indicate which material to prioritize, opting for the more stringent requirement can serve to protect both the primary construction project and the occupants or users of the structure.

Another alternative might be to consult with the project engineer; however, relying solely on that option can introduce potential delays or uncertainties in decision-making. In contrast, adhering to the most restrictive guidelines provides a clear, code-driven path that prioritizes safety.
