62 Recording datum line and connections to survey marks

A formal land survey plan must show the following—

(a) distinguishing characters used to identify the terminals of the horizontal datum line adopted for the survey and datum confirmation lines,

(b) the grid bearing adopted for accurate MGA orientation,

(c) the distance between the survey marks adopted for accurate MGA orientation,

(d) a comparison, for the horizontal datum line and datum confirmation lines, of measured bearings and distances with the bearings and distances derived from accurate MGA coordinates,

(e) if confirmation of the horizontal datum line and datum confirmation lines reveals differences that are more than the tolerance specified in section 22—the observed and calculated bearings and distances for all of the lines,

(f) the connection, by direct lines in a closed loop, between all survey marks adopted for accurate MGA orientation and confirmation of the survey,

(g) the connection, by direct lines to different corners of the land surveyed, of each survey mark used to determine accurate MGA orientation to form a closed loop,

(h) the horizontal datum adopted for orientation, stated adjacent to the north point on the plan, in an approved form.
