The following information relates to the different types of boundary marking surveys and their associated survey office (SO) CSD types, including a summary of survey and CSD requirements.
Depending on the complexity of the survey, a boundary marking survey must be either a:
- 'boundary reinstatement survey' which is recorded in Landonline as a 'Boundary Marking – Monumentation CSD' or a 'Boundary Marking – Reinstatement CSD', or
- 'full survey' which requires a full CSD and in Landonline is recorded as a ‘Boundary Marking – Full CSD (Conflict)'.
Note: the term 'full' is an informal term used in this guide to refer to a survey which includes witnessing, PRMs, etc and a CSD which includes information relating to definition, vectors, reporting, etc.
Depending on the quality of the existing survey work and the survey marks found, a boundary reinstatement survey may be recorded on one of two different types of survey office (SO) CSDs:
- Boundary Marking - Monumentation CSD. Where rule 11.1 criteria are able to be met, a boundary reinstatement survey without witness marks may be completed and recorded on a monumentation CSD [r 8.5(c)]
- Boundary Marking - Reinstatement CSD. Where rule 11.1 criteria are not able to be met, a boundary reinstatement survey with one witness mark but no PRMs [r 7.3.2(d) and r 7.4.1(b)] is to be completed and recorded on a CSD that complies with all the data requirements of rules 8.1, 8.2, and 9 (refer to Summary of survey and CSD requirements below).
The surveyor may choose to prepare a reinstatement CSD even though the monumentation CSD criteria are able to be met.
The placement of a boundary line mark can be treated as a boundary reinstatement survey, even though it is not reinstating a previously defined point. A monumentation CSD is not appropriate in these cases.
Where the survey does not meet the criteria for a boundary reinstatement survey (refer to definition of 'boundary reinstatement survey' in rule 2), then a full survey is required.
Where an existing boundary has been located, but the survey does not comply with the criteria for a boundary reinstatement survey [rule 2], a full survey must be carried out.
This survey must include three witness marks [r 7.3.1(a)] and two PRMs [r 7.4.1(a)].
Examples where a full survey must be carried out are where:
- the boundary point is subject to conflict [r 6.2(a)(vi)]
- the location of the boundary point is not sufficiently defined in an approved CSD [r 6.2(a)(vii)] (this includes boundary positions that are defined only on a 'diagram on transfer').
The survey purpose in Landonline for a full survey recorded on a boundary marking survey office (SO) CSD is Boundary Marking - Full CSD (Conflict). The CSD must include all the data requirements specified in rules 8.1, 8.2 and 9.
There are different requirements for each type of boundary marking surveys and their associated CSDs (refer to Boundary reinstatement survey CSD type and 'full' CSD for boundary marking survey above). Here is a summary of requirements:
Monumentation CSD *
Reinstatement CSD or Full CSD (Conflict) **
Not required [r 11.2(d)]
Not required [r 11.2(c)].
The old survey mark does not need to meet the witness mark criteria of r 7.3.3(b).
Not required [r 11.2(f)]
Normal requirements for both Boundary reinstatement survey and Full survey [r 8.2(a)]
Vectors in the CSD
Marks must be joined by one or more vectors which are depicted on the Diagram of Survey [r 11.4.1(d)].
Normal requirements for both Boundary reinstatement survey and Full survey (sufficient vectors to enable the relationship between the points to be ascertained [r 9.6.13(a)] and verified [r 8.1(d)]. This will normally require more than one vector between the points and can include adopted vectors).
Marks in the CSD
Must include boundary mark(s) placed and the old non-boundary survey mark [r 11.4.1].
Other old marks, such as might be used to obtain orientation or provide reliability, are not required (but can be included).
Normal requirements for both Boundary reinstatement survey and Full survey including old, new or adopted marks that have been used to determine the position of the marked boundary.
Two vectors for each point/mark
Not required [r 11.2(e)].
Normal requirements for both Boundary reinstatement survey and Full survey.
* Monumentation CSD (recording a 'boundary reinstatement survey' that meets the criteria of rule 11.1)
** Reinstatement CSD (recording a boundary reinstatement survey that does not meet the criteria of rule 11.1) or a Boundary Marking – Full CSD (Conflict) (recording a full survey)
