SPP-19 Validation and Examination Practices
Version 1 - 18/07/2018
The requisition procedure is used in cases of unacceptable mistakes and omissions concerning survey Plans and surveys.
Plans are stopped when significant survey problems occur or when surveys fail to comply with regulations or when Plan amendments are required. A requisition is raised informing the surveyor of the problems, the options for resolution and the associated fee. No further action on the Plan will be taken until the problems are resolved and the fee paid.
Surveyors are to arrange with the requisition examiner the most appropriate methods for effecting amendments to the plan.
Since September 1995 all requisitions have been graded as to severity and are recorded (indexed by surveyor) in a requisition database. While level 1 and 2 requisitions (i.e. those without a fee) pose negligible threat to a surveyor’s ‘Eligibility to Lodge’ status, a number of level 3 requisitions (with a fee charged) in a short period could accumulate to threaten that status. Two level 4 requisitions would be an immediate threat.
A history of continual level 3 requisitions will be taken into consideration in deciding the form of more severe disciplinary action in the event of a later severe breach by a surveyor.
The Land Surveyors’ Licensing Board website contains detailed information on breaches and their related severity. The information can be found at http://www.lslb.wa.gov.au/for-licensed-surveyors/requisition-severity-levels. The tabs along the bottom of the excel spreadsheet allow access to the various worksheets in the file.
Plan examination is to proceed in accordance with Landgate’s standard checklist.
Breaches will accumulate as assessed from Standardised requisition criteria at http://www.lslb.wa.gov.au/for-licensed-surveyors/requisition-severity-levels.
Accumulation to level 3 severity or above will incur a requisition fee. Accumulation to level 2 severity or below will not incur a requisition fee.
All required amendments to the plan due to breaches are to be carried out by the surveyor and the amended plan (with a version increment) to be submitted via NLR using the “Amend plan” function.
The statement “Plan examination requirements” is to be inserted into the amendments table.
Amended plans do not incur a fee.
The processing of survey sheets by the Spatial Data team is considered a plan examination task, and the requisition procedures stated above apply.
The following procedure applies upon the request from a surveyor to replace a CAD Plan (PDF) that was lodged that day or the previous day:
Plan PDF not signed – if this is the only thing missing from the plan, the surveyor can re-submit the plan as an Amended plan (with a version increment). This does not incur a replacement plan fee. Please contact Landgate at firstname.lastname@example.org before submitting the amended plan.
Material changes to the subject of the plan (e.g. changes to dimensions) - must be lodged as a Replacement plan (with a version increment), using the “Replace plan” function in NLR. A replacement plan fee applies.
For any other surveyor-initiated changes to the plan which could be argued as not being material, the surveyor has a choice: (a) Treat as a Replacement plan and incur a replacement plan fee, or (b) Wait for manual examination of the plan; in which case the standard examination procedure will apply.
Note that the above procedure only applies when a surveyor requests to amend or replace a plan before it reaches a plan examiner. Standard examination procedures, fees and charges are to apply after the examination process has started.

The survey examination function of the Inspecting Surveyors includes:
- checking the field records lodged by surveyors.
- examining the definition and marking of the boundaries on a sample of surveys.
- assisting surveyors to maintain and improve the standard of cadastral surveys.
2.1 Office Inspections
Most field books lodged at Landgate are visually inspected as to the following items:
- Check that it is signed and dated, that any deletions are correct and the date of survey, in case a 2-year certificate is required.
- Check that adequate information is provided (especially for SSA subdivisions) and that there is only one index page which includes all the surveys in the book.
- Check that all information is legible and suitable for reproduction.
- Check that sufficient marks have been found and that the correct method has been used (sparse pickup and/or poor method are common triggers for field inspection).
- Check the recording of measurements, reductions to true line, comparisons with original, descriptions of marks found and other general matters. Check SSA requirements including connections from control to new boundaries. Check method and presentation of surveys by GPS. Doubts caused by omissions or anomalies will usually trigger a field inspection.
- Check that quantity and type is in accordance with the regulations and guidelines. Check that the pickup is adequately protected.
- Check that connections have been carried out in accordance with the guidelines under General Regulation 22A or guidelines for Special Survey Areas.
2.2 Field Inspections
Field inspections enable the field record to be compared with the actual field environment.
Inspection of the marking determines:
- Whether the regulations and guidelines have been adhered to;
- Whether all exceptions to the regulations have been recorded in the field notes, and
- The overall standard of the marking for the public including clarity of lot numbering on pegs/posts and witnessing of the marks.
Field measurements enable two standards of accuracy to be determined:
- Accuracy of re-establishment, or how well the survey fits in to the existing cadastre, and
- Plan accuracy, or how well the marks fit with the dimensions on the Plan of survey.
Both of these measures include a component of comparison between the measuring devices of the surveyor and of the inspector. Subdivisions within Special Survey Areas are a special case where the accuracy of the survey is compared with the accuracy specifications in the guidelines by means of a coordinate check.
Standards of quality are expressed as:
- HIGH (or ACCURATE)
- UNACCEPTABLE (or POOR)
2.3 Survey Examinations
Inspecting Surveyors are frequently required to carry out an office examination (either full or partial) of a survey. This involves determining whether the surveyor has achieved a correct definition of the boundaries of the land the subject of the plan of survey.
