Excavations greater than what depth must be designed by a registered professional engineer?

• A. 10 feet
• B. 15 feet
• C. 20 feet
• D. 25 feet

Answer: (C)

Excavations greater than 20 feet in depth must be designed by a registered professional engineer due to safety and structural integrity concerns. At this depth, the risks associated with cave-ins, soil stability, and potential hazards increase significantly. Engineers are trained to assess the type of soil, environmental conditions, and other factors that can affect the safety of deep excavations. This requirement ensures that appropriate measures, such as shoring and bracing, are in place to protect workers and prevent accidents. The regulation reflects best practices for excavation safety, emphasizing the necessity of professional judgment in the design process to mitigate risks associated with deep excavation work.
