Surveying and Spatial Information Regulation 2024

This section applies to a land survey carried out to—

create, redefine or widen a road under an Act, or

define a road frontage of a lot.

A surveyor must insert a reference mark for each point on the land surveyed to reference the following—

if the land surveyed abuts a road—the extremity of the land fronting the road,

each terminal of the road created or defined,

each intersection with other roads,

if the intervening side boundaries are not more than 250m apart—

each angle of the road, and

each tangent point of a curve or arc in the road, and

the terminal of a series of chords of a regular curve in the road.

The maximum distance between 2 successive reference marks along a road frontage must not be more than—

for an urban land survey—

if there are intervening side boundaries—100m, or

otherwise—250m, or

for a rural land survey—1,000m.

A surveyor must insert a reference mark at the intersection of road boundaries—

if a triangle is cut off from the corner formed by the intersection—to mark either end of the base line of the triangle or the point of intersection, or

if the corner is rounded off—to reference either tangent point or the point of intersection, or

if the corner is not cut off or rounded off—to reference the point of intersection.

A surveyor must, as far as is practicable, insert reference marks—

to reference the same side of the road, and

in pairs suitable for orientation purposes along the road.

For a survey to create, redefine or widen a road under an Act, there must be 2 reference marks if a reference mark consists of a drill hole and wing.

If a road being created joins or intersects an existing road with reference marks, a surveyor must—

connect the existing marks to the reference marks inserted in the road being created, and

compare the orientation of the existing marks with the orientation of the new reference marks, and

define the existing road in the survey, and

compare the orientation of the existing road using existing plans.
