Whether you’re buying a new property, planning a development project or simply looking to renovate your existing home, land surveys play a key role in planning the work. Land surveys, more commonly known as cadastral surveys, are a range of professional services that are used to identify the boundaries, features and terrain of a property. This information is important when obtaining council approvals, but it also has a major impact on how construction companies approach their work. While cadastral surveyors offer a broad range of services, there are a few common survey types found throughout the industry. In this article we’ll be discussing the four main types of cadastral surveying and the role they play in executing projects.
1. Boundary Surveys
Boundary surveys – also known as identification surveys – are a type of cadastral survey that’s used to locate the exact borders of a property. Boundary surveys are a critical part of all construction and development projects.
The features along the boundaries of a block shift slowly over time. Changes to fences, movement in the land and new construction projects can all cause confusion about the exact boundaries of a property. Boundary surveys are designed to clear up these issues. During a boundary survey, a professional team will perform historical research into the original property title. They will then use precise measuring equipment to mark out the boundary lines, location and size of a property. The results of boundary surveys play an important role in construction, development and subdivision projects.
2. Feature Surveys
The size and location of a property aren’t the only things that matter to construction projects. Other features of the site also play a role. Feature surveys are designed to provide detailed information about major details of the property, such as:
- Existing buildings and structures
- Vegetation and trees
- Retaining walls
- Fences
- Utility and service runs
- Neighbouring properties and structures
This information is especially useful in larger-scale developments. The details of a feature survey can be used to improve the accuracy of timelines and trade estimates, and it helps to avoid costly mistakes like damaging utilities.
3. Topographic Surveys
The contours and terrain of a block play a major role in the design and planning of development projects. Simple issues such as gentle slopes can complicate the building process, so topographic surveys are designed to provide detailed information to aid planning. Modern cadastral surveyors often use sophisticated LiDAR sensors and drones to capture terrain information. Depending on your needs, a surveyor can even use aerial surveying to produce a 3D render of the site that can be used for modelling the project using CAD technology.
4. Construction and Engineering Surveys
Many types of cadastral surveying are conducted as part of the planning and approvals process. Beyond that, surveyors are often required throughout construction to ensure the accuracy of the work being performed. Construction and engineering surveys are conducted before, during and after the work is completed. Some of the most common construction and engineering surveys include:
- Preconstruction surveys. Before work can begin, preconstruction surveys are used to identify existing defects and damage to sites that are adjacent to construction work.
- Set-out surveys. Surveyors use precise measuring equipment to mark out the exact location of any structures being built according to the approved plans.
- Site monitoring. Monitoring surveys can identify small movements on construction sites and structures. This requires making multiple visits to the site to take measurements that can then be compared to detect movement.
- As constructed surveys. Once construction is complete, builders are usually required to produce an as constructed survey/ADAC to show the final result of the building work.
