How high must temporary project fencing extend above grade?

Temporary project fencing must extend a minimum of 4 feet above grade to ensure safety and security on construction sites. This height is designed to deter unauthorized entry and provide a visible boundary for workers and the public. The 4-foot standard allows for adequate visibility while still serving as an effective physical barrier.

A lower height may not provide sufficient deterrence or security, while higher fencing could complicate access for maintenance personnel or emergency responders. The 4-foot standard strikes a balance between security needs and practicality in construction environments. Therefore, this height is recognized as compliant with safety regulations and best practices in project site management.
