town planning for subdivision


A cadastral surveyor has an important role in accurately defining property boundaries and understanding land ownership laws. They perform tasks such as identifying residential or rural boundaries, re-establishing previously surveyed boundaries, and creating new boundaries during land subdivision. Cadastral surveyors possess the knowledge and skills to interpret and advise on boundary locations and any related property rights or restrictions. The information and measurements collected by the surveyor are recorded on a survey plan, which is then submitted to the relevant government agency for documentation. Steffan Harries works alongside various surveying firms to assist in the development application process, especially for subdivision projects.

Builders utilise plans and drawings as blueprints to construct buildings and other structures. In addition to their construction expertise, builders may also provide project management services and take charge of managing the development application process on behalf of the property owner.

For further information, you can visit the Queensland Master Builders.

Building certifiers

Building certifiers have the crucial role of evaluating whether proposed building work adheres to the Building Act 1975 and its related standards. The certifier who issued the building permit is also responsible for conducting inspections to verify compliance with the approved plans.

If you require a siting variation assessment against the performance criteria of the Queensland Development Code (QDC), it is essential to engage a building certifier. They can provide you with valuable technical advice on siting variations and serve as the assessment manager for such applications.
