A. Primary Monuments.
1. Alloyed iron pipe, zinc-coated, or aluminum pipe:
a. Outside diameter, two inches or larger;
b. Cut in 30-inch lengths;
c. One end of the pipe shall be split for several inches and the two halves spread to form flanges or commercially manufactured foot attached.
2. A brass or aluminum cap two and one-half inches or larger in diameter shall be securely attached to the other end by mechanical means.
3. If aluminum pipe is used, the monument must contain a magnetic insert as an integral part of its compositions.
4. Driven iron or aluminum rod five-eighths-inch minimum diameter and driven to a minimum nine-foot depth or point of refusal.
a. If sectional rods are used, segments shall be secured to one another so that joints tighten up on further driving.
b. A two-and-one-half-inch aluminum monument shall be secured to the surface end by friction or mechanical means.
c. If an aluminum rod is used, the monument must contain a magnetic insert as an integral part of its composition.
5. In areas where primary monuments are located on rock outcrops or concrete surfaces, a brass or aluminum tablet two-and-one-half-inch diameter with a one-half-inch diameter stem shall be cemented into a drilled hole.
B. Secondary Monuments.
1. Cap one and one-half inches or larger secured by friction fit or mechanical means to five-eighths-inch steel rebar or other ferrous metal rod.
2. The rods shall penetrate a minimum of 30 inches below the surface.
3. Plastic stakes specifically designed for survey purposes are allowable if they meet penetration requirements and are detectable by commonly used metal detectors.
4. In areas where secondary monuments are located on rock outcrops or concrete surfaces, the procedure for primary monuments shall be followed.
C. Reference Monuments.
1. Minimum requirements are the same as those for secondary monuments.
2. All reference caps will be marked with the following information:
a. Distance to monument referenced;
b. Surveyor’s license number;
