Residential Building Inspector Practice Exam

When wood floor systems are not in accordance with the International Residential Code, what standard can be followed?

1. AWC NDS

2. ASHRAE Standards

3. ICC Standards

4. ANSI Standards

The correct answer is: AWC NDS

When wood floor systems do not comply with the International Residential Code, the appropriate standard to refer to is the AWC NDS, also known as the American Wood Council's National Design Specification for Wood Construction. This document provides detailed guidance on the design, structural properties, and uses of wood in construction. It includes information on wood species, strength properties, and various design criteria essential for ensuring the safety and performance of wood floor systems. The relevance of the AWC NDS is critical because it specifically focuses on wood construction, making it particularly suitable for addressing issues related to wood floor systems. This standard incorporates current research and methods to ensure that wooden structures adhere to safe engineering practices, promoting durability and compliance with recognized construction standards. The other standards mentioned, while important in their own right, do not specifically cater to wood design in the way that the AWC NDS does. For instance, ASHRAE Standards focus on heating, refrigeration, and air conditioning systems rather than structural applications. ICC Standards provide a framework for building safety and regulations but may not offer the specific guidelines necessary for wood design. ANSI Standards cover a broad range of standards but do not singularly address the intricacies of wood construction like the AWC NDS does.
