What is the minimum diameter for metal monuments according to the standards?

The minimum diameter for metal monuments, as per the established standards in surveying practices, is half an inch. This specification ensures that the monuments are sufficiently robust for identification and can withstand environmental factors without being easily displaced or damaged. Monuments serve as reference points for property boundaries and other critical measurements, so it's essential they have a diameter that balances visibility, durability, and cost-effectiveness. This half-inch size provides adequate strength while maintaining a manageable profile for installation and use in various survey contexts.
