When designing a structure greater than three stories, which code must be referred to?

• A. UBC
• B. IBC
• C. IRC
• D. ADA

Answer: (B)

In the context of designing a structure greater than three stories, the International Building Code (IBC) is the code to refer to. The IBC governs the construction and design of all types of buildings, including those that exceed three stories in height. It provides comprehensive requirements regarding structural integrity, life safety, accessibility, and overall building performance, which are essential for ensuring the safety of taller structures. The IBC addresses various critical aspects such as fire safety, egress requirements, structural systems, and occupancy classifications, which are particularly pertinent for multi-story buildings. In contrast, the other codes listed, like the Uniform Building Code (UBC) and the International Residential Code (IRC), serve specific contexts. The UBC is an earlier building code primarily used in certain jurisdictions, while the IRC is focused on residential occupancy and generally applies to one- and two-family dwellings, making it unsuitable for structures over three stories. The ADA (Americans with Disabilities Act) primarily pertains to accessibility standards rather than overarching building codes. Thus, the IBC is the appropriate reference for this type of project, ensuring compliance with modern standards and safety regulations for taller buildings.
