Surveying solutions for property, land and infrastructure

Every project starts with a different question.

You may need to understand whether land can be subdivided, establish where a property boundary lies, capture the existing conditions of a building or survey an infrastructure corridor across difficult terrain.

Treasco Surveyors takes the time to understand what you are trying to achieve, how the survey information will be used and which other professionals are involved. We then recommend a scope and survey method appropriate to your site, project stage and intended outcome.

Our services combine professional surveying knowledge with technologies including GPS, aerial drones, photogrammetry, LiDAR and 3D laser scanning.

Our core services

3D laser scanning

3D laser scanning

Capture a detailed digital record of a building, structure or site.

3D laser scanning collects extensive spatial information about visible surfaces and converts it into a three-dimensional point cloud. This can support existing-condition documentation, architectural and engineering design, construction verification, heritage projects and complex building-services coordination.

It is particularly useful for irregular structures and spaces that would be difficult or time-consuming to measure manually.

  • Point cloud data
  • Existing-condition plans
  • Floor plans, elevations and sections
  • Data for agreed CAD or BIM workflows

Aerial drone surveying

Aerial drone surveying

Capture large, remote or difficult-to-access sites efficiently from above.

Treasco Surveyors uses drone photogrammetry and aerial LiDAR where appropriate to collect high-resolution imagery and three-dimensional spatial information. Aerial surveying can provide valuable context across rural properties, development sites, construction projects, infrastructure corridors and environmental areas.

Drone data may also be combined with ground-based surveying to establish control, verify important features or capture details that cannot be seen clearly from the air.

  • Orthophotos and aerial imagery
  • Point clouds and surface models
  • Topographic information
  • Stockpile and earthworks volumes

Property development surveying

Property development

Surveying support from early feasibility through design, approval, construction and completion.

Property development involves interconnected questions about boundaries, terrain, access, drainage, easements, services and planning requirements. Identifying these matters early gives developers and consultants a stronger foundation for design and decision-making.

Treasco Surveyors works with developers, architects, engineers, planners, solicitors, builders and councils to coordinate the survey requirements at each stage.

  • Site and title investigations
  • Detail and level surveys
  • Development feasibility
  • Construction set-out

Rural surveying

Rural surveying

Practical surveying services for farms, rural holdings and large land areas.

Rural properties can involve extensive boundaries, historical survey information, difficult access and varied terrain. We use appropriate combinations of conventional surveying, GPS, drone technology and LiDAR to collect reliable information efficiently.

Our rural surveying services support property ownership, fencing, access, subdivision, development, infrastructure and land-management decisions.

  • Rural boundary surveys
  • Rural subdivisions and boundary adjustments
  • Easement surveys
  • Aerial mapping

Subdivision planning

Subdivision planning

Understand the potential of your land and the process required to create new lots.

Subdivision feasibility depends on more than property area. Planning controls, access, services, drainage, easements, terrain, environmental matters and council requirements can all influence the outcome.

Treasco Surveyors assists with residential, rural and development subdivisions from initial investigation and concept planning through cadastral survey, certification and registration.

  • Feasibility and concept planning
  • Detail and boundary surveys
  • Development application plans
  • Formal subdivision plans

Energy and construction surveying

Energy and construction surveying

Reliable spatial information for infrastructure design, delivery and asset records.

Treasco Surveyors works with energy companies, network providers, engineers, principal contractors and construction professionals on power lines, communication towers, access tracks and related civil infrastructure.

We can support projects from route investigation and existing-condition surveys through survey control, construction set-out, progress measurement and final as-built documentation.

  • Power-line and infrastructure corridor surveys
  • Survey control
  • Construction set-out
  • Work as executed and as-built surveys

The service required will depend on your objective, property and project stage. If you are unsure which survey applies, begin by explaining the decision you need to make rather than trying to select a technical survey type.

Not sure which survey you need?

You do not need to know the technical name of the survey before contacting us. Start with the question you need answered.

Your objective A likely starting point
Confirm a property boundary Boundary or cadastral survey
Design a new building or extension Detail and level survey
Investigate subdivision potential Title review and subdivision feasibility
Capture a complex existing building 3D laser scanning
Survey a large or remote site Aerial drone or LiDAR survey
Position proposed construction Construction set-out
Record completed works Work as executed survey
Calculate stockpile or earthwork volumes Volume or surface survey
Create an access or utility right Easement survey and plan
Survey rural land or infrastructure Rural, corridor or aerial survey

Some projects require more than one survey method. We can recommend a coordinated scope so that the information collected at one stage remains useful at the next.

Our approach

01. Understand the outcome

We begin with the reason for the survey. Knowing whether the information is for a purchase, design, approval, legal matter or construction task helps us define the right scope.

02. Review the available information

Where relevant, we review title documents, existing survey plans, design files, approvals and other project information.

03. Recommend an appropriate method

We consider the required accuracy, site conditions, access, terrain, vegetation, project area and final deliverables before recommending a survey approach.

04. Complete the fieldwork

Our team collects the required measurements using the technology and procedures appropriate to the project.

05. Process and check the information

We assess the collected data, undertake appropriate checks and prepare the agreed plans, models or digital files.

06. Support the next stage

We explain the outcome and can coordinate with your architect, engineer, planner, solicitor, builder, council or other project professionals where required.

Frequently asked questions

That depends on the question you need answered. Tell us about the property, project and intended use of the information, and we can recommend an appropriate starting point.
Contacting a surveyor early can help identify boundary, terrain, access, easement or documentation requirements before substantial design, purchase or construction commitments are made.
Useful information includes the property address, lot and deposited plan details if available, a description of the proposed work, relevant plans or approvals, required deliverables and your preferred timeframe.
Yes. We work with architects, engineers, planners, solicitors, ecologists, builders, councils and other professionals. Early coordination helps ensure the survey captures the information they require.
Sometimes information can be reused, but different stages may require different accuracy, features, legal status or deliverables. We can plan the initial scope with later project needs in mind.
No. Technology is selected according to the project. Conventional surveying may be the best method for some work, while drones, LiDAR or 3D laser scanning can improve efficiency and coverage for others.
No. Imagery may show fences and other occupation, but legal boundaries require appropriate cadastral investigation and survey work.
The required and achievable accuracy depends on the purpose of the survey, equipment, method and site conditions. These requirements should be established when the work is scoped.
Timeframes depend on the type of survey, property size, location, access, terrain, available records and final deliverables. Projects involving approvals, authorities or registration can also depend on third-party response times.
Deliverables may include survey plans, coordinates, CAD files, point clouds, aerial imagery, surface models, three-dimensional models or formal cadastral documentation. The exact outputs will be agreed before work begins.
