There's a big network of survey marks around the ACT. Survey marks tell you important information on where things are.
Survey marks are a key element in the infrastructure of the ACT. This means that survey marks are protected by the Surveyors Act 2007.
Survey mark status
Survey marks can become damaged, destroyed, or difficult to find.
The Office of the Surveyor-General and Land Information (OSGLI) manages the maintenance of survey marks in the ACT. OSGLI supplies the surveying industry with current information on survey marks. This means it's important to report the status of survey marks to OSGLI as soon as possible.
You might need to report a survey mark status if you:
- find the mark has moved
- find a damaged mark
- can’t find the mark or
- are planning works that might affect a mark.
Anyone can report the status of a survey mark. You'll need to know the:
- mark type
- mark number or name and
- mark status.
You can report a survey mark status by emailing actplasurvey@act.gov.au.
Survey mark status description
| Status | Description |
|---|---|
| Gone | The mark is missing. Physical evidence of removal, or an extensive search using all information available shows the mark is gone. |
| Not found | The mark might not be found. An initial search might show the mark is gone. No thorough search has been completed. |
| Damaged | The mark is physically damaged. The damage may affect its horizontal or vertical spatial position. |
| Good | The mark is undamaged and in its original position. |
| To be destroyed | The mark will be destroyed soon. You'll need permission from the ACT Surveyor-General to destroy a survey mark. Early advice allows a surveyor to replace the mark. |
Updating spatial position of survey marks
Sometimes horizontal or vertical coordinates of survey marks are incorrect in the Survey Control Mark Register. This can be because of older surveys or mark movement.
If you have updated horizontal or vertical coordinates, you can help update the database. You can do this by emailing actplasurvey@act.gov.au.
