Colorado Land Surveyor Practice Exam

Which statement is true regarding the durability of a monument cap?

1. The cap may be a plastic material

2. The cap must be at least 1 inch in diameter

3. The cap must be durable metallic if the monument lacks a cap

4. The cap can be of any material if it has markings

The correct answer is: The cap must be durable metallic if the monument lacks a cap

This statement about the cap of a land survey monument being required to be a durable metallic material if the monument lacks a cap is grounded in the standards set for monument durability. A durable metallic cap ensures the longevity and stability of the monument, which is crucial for maintaining accurate boundary reference points over time. In surveying, reliable monuments are essential for legal and practical purposes, as they often serve as critical reference points in property delineation. If a monument does not have a cap, using a metallic cap offers resistance to environmental factors like weathering, abrasion, and potential impacts from wildlife or human activities. This durability helps preserve the integrity of the survey data collected from that monument. Other choices might suggest alternative materials or requirements, but they don't adhere to the standard for maintaining the quality and effectiveness of the monument over time. For example, while a plastic material may be more cost-effective, it does not provide the same level of durability that is needed in the long term for a survey monument. Thus, the requirement for a metal cap clearly aligns with the principles of ensuring that survey markers remain intact and functional in the face of various external factors.
