| (a) | is approximately 12 mm in diameter and 400 mm long; |
| (b) | is driven solidly into the ground so that approximately 50 mm thereof protrudes above ground level; and |
| (c) | is placed in a position where it is out of reach of flood water and will not silt up. |
| (2) | The soil around an iron peg referred to in subregulation (1) shall be dug out to a depth of approximately 250 mm and over an area of approximately 300 mm by 300 mm, and the hole concerned shall thereafter be filled with concrete to such extent that approximately 12 mm of the iron peg concerned protrudes above the concrete. |
| (3) | The protruding surface of the concrete referred to in subregulation (2) shall be bevelled away from the iron peg concerned, and the following particulars shall be imprinted on the bevelled surface while the concrete is still wet: |
| (a) | The number of the survey point or bench mark concerned; |
| (b) | a directional line with arrowhead pointing to the next permanent survey point or bench mark; |
| (c) | a directional line without arrowhead pointing to the nearest temporary survey point referred to in subregulation (6); and |
| (4) | A permanent witness beacon shall be placed approximately 2 metres away from each permanent survey point or bench mark referred to in subregulation (1). |
| (5) | A permanent witness beacon referred to in subregulation (4) shall be an iron standard— |
| (a) | that is approximately 1 370 mm long; |
| (b) | with four alternating white and red bands, each approximately 150 mm wide, painted around the upper portion with a durable paint; and |
| (c) | that is driven solidly into the ground so that approximately 900 mm thereof protrudes above ground level: |
Provided that the provisions of regulation 27(3)(a) and (b) shall apply mutatis mutandis with regard to such permanent witness beacon erected on soft or sandy ground or hard or rocky ground, as the case may be.
| (6) | A beacon that serves as a temporary survey point or bench mark for the proposed building site of a soil conservation work shall be an iron peg:— |
| (a) | that, in the case of a contour bank system, is approximately 5 mm in diameter and 300 mm long; |
| (b) | that is otherwise approximately 12 mm in diameter and 400 mm long; |
| (c) | that is driven solidly into the ground so that approximately 25 mm thereof protrudes above ground level; and |
| (d) | to which a suitable aluminium tag is affixed on which the number of the survey point or bench mark concerned and the letters L/A appear. |
| (7) | If it is deemed necessary, a temporary witness beacon that complies with the requirements set out in subregulation (5) may be provided approximately 2 metres away from any temporary survey point or bench mark referred to in subregulation (6). |
| (8) | A beacon that is used as a survey point or bench mark in terms of this regulation shall be placed in such a position with regard to the soil conservation work for which it is used that it will not be damaged, destroyed, removed or shifted during the construction of the soil conservation work concerned. |
