The following information relates to CSDs with a computed boundary point.
Historically, a computed plan was defined as a plan prepared either under the proviso in s 167(1) of the Land Transfer Act 1952 or any similar dispensation granted by the Surveyor-General. It was a CSD prepared where a new boundary point was computed without any field survey.
The dataset type was used for all classes of survey where one or more of the boundaries and boundary points of a new parcel were calculated without any boundary marking on the ground.
The current Rules do not use the term computed plan.
Rule 7.1 specifies the conditions where a primary parcel boundary point must be marked. Where a new primary parcel boundary point is not required to be marked, it must still be defined by survey [r 6.2(a)(iv)] and witnessed [r 7.3.1(a)].
Where a CSD only contains non-primary parcels, no new parcel boundary points are required to be marked, witnessed, or to have PRMs [r 7.3.1, r 7.4.1(a)].
Note, there is an exception with some types of non-primary lease boundary points where boundary points must be witnessed [r 7.3.1(b)] and new stratum boundary points where there must be heighted PRMs and witness marks [r 7.3.1(d) and r 7.4.3(d)].
The Rules do not require the notation Computed CSD on the diagrams or included in the CSD.
