The following objects shall be considered as monuments/markers of permanent nature: a. Boundary Monuments. For ADs, rectangular parallelepiped concrete monuments measuring 25 cm x 25 cm x 100 cm, set 80 cm. on the ground shall be installed, with “ADBM NCIP” (Ancestral Domain Boundary Monument NCIP) inscribed on top. For ALs, cylindrical concrete monuments measuring 20 cm. in diameter and 80 cm. in height or rectangular parallelepiped concrete monuments measuring 20 cm. x 20 cm. x 80 cm., set 60 cm. on the ground shall be installed, with “ALBM” (Ancestral Land Boundary Monument) inscribed on top. The foregoing monuments shall be centered with a galvanized iron spike, nail, rod or conical hole (not exceeding 2 cm in diameter and not less than 1 cm in depth). Inscriptions shall be at least 0.50 cm deep. b. Intermediate corners. Intermediate corners shall be defined by rectangular parallelepiped concrete monuments measuring 15 cm x 15 cm x 60 cm, set 50 cm on the ground and inscribed on top with “ADBM” for AD or “ALBM” for AL and centered with galvanized iron spike, nail, rod or conical hole (not exceeding 2 cm in diameter and not less than 1 cm in depth). Inscriptions shall be at least 0.50 cm deep. c. Immovable or Fixed Hard Rocks/Boulders. The corners of the AL/AD may be defined by immovable or fixed hard rocks or boulders with surface exposed measuring not less than one (1) meter in diameter. The same shall be marked either with an “x” chiseled thereon or patched with cement putty centered with a hole, spike, or nail, and labeled correspondingly. d. Other Monuments. The following objects shall also be considered as monuments of permanent nature: 1. 2. 3. Concrete posts of fences with outside diameters measuring at least twenty (20) cm. Living edible fruit trees or trees belonging to the first group measuring at least fifteen (15) centimeters in diameter Points on masonry or concrete walls e. Witness Corner Monuments (WCM). When the AL/AD being surveyed involves inaccessible/submerged corners, at least two (2) “witness monuments” shall be established as near as possible to the said corner/boundary. The corners defined by the witness points should be visible from the inaccessible points. The witness corner may be set using a cylindrical concrete monument that is 15 cm diameter and 60 cm long and set 40 cm on the ground. The letters “WCM” shall be engraved in such monuments. The location of witness monuments shall be indicated on the survey plan. RULE V PRESCRIBED SURVEY RETURNS AND FORMS/FORMATS Section 1. Survey Returns.
