Leaving excavations open for longer than 120 calendar days incurs what type of violation?

Leaving excavations open for longer than 120 calendar days incurs a grave violation due to the increased safety risks and potential hazards associated with prolonged open excavations. Such situations can lead to unstable conditions that may endanger the lives of workers and the public, as well as damage property. The law typically categorizes violations based on the severity of their consequences, and grave violations are often associated with significant safety concerns, potential harm to individuals, or considerable disruption to the surrounding environment.

In this context, excavations that remain open beyond the stipulated time frame can lead to serious accidents or injuries, thereby warranting a more severe classification. This classification emphasizes the importance of adhering to established safety regulations and timelines in construction practices. Other classifications, such as minor or less grave violations, generally pertain to issues that do not pose a direct and serious threat to safety or welfare. Thus, the grave designation for this scenario reflects the serious nature of the violation and the urgency of remedying it to ensure safety and compliance with building laws.
