Victorian Numbered Regulations Victorian Numbered Regulations(1) A permanent mark established under the Act must be in a place—
(a) where it is least likely to be subject to damage, disturbance or removal or to constitute a hazard; and
(b) to facilitate horizontal and vertical connections to existing and future marks; and
(c) where it is readily identifiable and easy to find; and
(d) that provides the most stable location available.
(2) If a box-cover [2] is used to protect a permanent mark, it must be—
(a) constructed of durable and permanent material and in a rigid manner enabling the maximum protection that is practicable to be afforded to the permanent mark; and
(b) set centrally over the permanent mark with the top of the cover flush with the ground or surface on which it is set and the base not less than 50 millimetres above the top of the permanent mark.
(3) If a marker post or indicator is used to locate or protect a permanent mark, the marker post or indicator must be placed vertically in the ground where it does not constitute a hazard, not less than 300 millimetres from the centre of the permanent mark and independent of any medium in which the permanent mark is set.
(4) Permanent marks on surveys of 1500 metres or more in length must be placed so that no two marks are more than 1500 metres apart unless the Surveyor-General directs under section 6(1)(b) of the Act the establishment of other intervals.
