Survey control reports of marks are free and include the permanent survey mark plan. Under the Queensland Government's open data initiative, we have published survey control information through the Location category globe in the Queensland Globe. If you have a query on the interference of a survey mark, email with details of the mark and the interference. A cadastral search of the area and/or a cadastral survey may be required to be carried out.

If a project you are undertaking is likely to interfere with a permanent survey mark, email with details of the mark(s) and the project.Īn assessment will be made to determine the impact of the interference on the state geodetic control network and if any survey work is required before the mark(s) are disturbed. Permanent survey marks can only be interfered with or removed after written approval from the Department of Resources. This will show whether there is the potential to interfere with survey marks. If you are conducting this type of work, take care not to interfere with survey marks.īefore starting construction works, consider engaging a registered cadastral surveyor to carry out a search of the construction area. For example, it can affect construction projects that depend on accurate positioning and height information and lead to increased costs to landholders when they need to get their boundaries resurveyed. Removing, disturbing or destroying survey marks is costly to the community. Under section 42 of the Survey and Mapping Infrastructure Act 2003 it is an offence to interfere with a survey mark without approval.
