Inspection of Survey Plans
After a lot number is assigned to a parcel of land or a property, a cadastral survey of the land is carried out to obtain an accurate measurement of the boundaries of the real property. The survey is required for or in connection with the registration of any title to the land or a property.

When the cadastral survey is completed, a survey plan, showing the location of the land/property and its boundaries, area, lot number, boundary marks emplaced on the land/ property and the approved coordinates, is lodged with the SLA. The plan has to be approved by and filed with the Chief Surveyor.


Survey plans
There are 2 types of plans:
  1. Registrar of Titles (RT) Plan
    These are survey plans prepared for the survey of subterranean lots, airspace lots, reclaimed lands and foreshore structures. The plans show the provisional boundaries and areas, which are subject to alteration upon final survey of the lots.
  2. Certified Plan
    These are survey plans prepared upon final survey of the land and strata lots. The plans are called Certified Plan (CP) for land lots and Strata Certified Plan (CPST) for strata lots.


Service standard

The service standard for the Chief Surveyor to approve the survey plans are:
  1. For processing RT job - Within 7 working days
  2. For processing CPST job - Within 10 working days
  3. For processing CP job - Within 10 working days
  4. For issuing new lot numbers - Within 2 working days

The time frame for the above service levels does not include any period of time for the following situation:
  1. The query period from the date the Chief Surveyor notifies the Registered Surveyor of any query to attend to the date the Registered Surveyor returns the job upon attending to the query.
  2. All Saturdays, Sundays and public holidays.
  3. Any period for which consultations are made with other parties to resolve any issue.

These periods, where applicable, are taken as stoppage time to offset such periods from the time frame of the service level.
