A shoulder barrier must be constructed to what engineering standards?

• A. Local municipality standards
• B. Accepted engineering standards
• C. International construction standards
• D. Safety regulations only

Answer: (B)

A shoulder barrier must be constructed to accepted engineering standards because these standards have been established to ensure safety, stability, and functionality in construction practices. Accepted engineering standards are typically developed by professional organizations and reflect best practices based on research, experience, and consensus within the engineering community. Adhering to these standards ensures that the shoulder barrier will meet the necessary structural integrity requirements needed to protect both workers and the public.

Local municipality standards may vary and might not incorporate the most up-to-date engineering practices, while international construction standards could be too broad or not applicable to local conditions. Focusing solely on safety regulations might overlook crucial structural and engineering considerations needed for proper barrier construction. Therefore, relying on accepted engineering standards ensures a comprehensive approach that encompasses safety, performance, and compliance with necessary guidelines for such structures.
