Why Property Flags Matter on the Jobsite
Property flags may look simple, but their role in site accuracy and safety is critical. Here’s why professionals rely on them daily:
1. Boundary Clarity and Legal Accuracy
-
Surveyor flags for marking property lines make it easy to see boundaries before fencing, trenching, or grading.
-
Using distinct colored flags for underground utilities or perimeter zones helps crews stay compliant with municipal and OSHA standards.
2. Safety During Excavation and Utility Work
Utility contractors depend on heavy-duty property marking flags to mark gas, water, and cable routes. Bright, consistent colors help prevent accidental strikes and ensure safe digging.
