Surveying for energy and infrastructure
Energy and infrastructure projects depend on reliable spatial information.
A small error in position, level or alignment can affect design coordination, clearances, access, construction and the accuracy of final asset records. Survey requirements may also change as the project moves from route selection and design through construction, commissioning and maintenance.
Treasco Surveyors develops a survey approach around the asset, terrain, project stage and information required by the wider team.
We can work alongside asset owners, engineers, environmental consultants, planners, construction managers, contractors and landholders to help maintain consistent information throughout the project.

Benefits of coordinated infrastructure surveying
- Reliable design information
Accurate terrain, feature and asset data gives engineers and designers a stronger foundation for planning and documentation.
- Consistent project control
An established control framework helps align design, set-out, contractor measurements and as-built information.
- Efficient coverage
Ground surveying can be combined with drones, LiDAR or laser scanning to collect information across extensive or complex sites.
- Reduced site exposure
Remote data collection may reduce the need for personnel to enter some steep, difficult or operational areas. It does not remove the need for project-specific safety planning.
- Better coordination
Clear survey deliverables help owners, engineers, contractors and consultants work from consistent spatial information.
- Defensible project records
Progress and as-built surveys create records of site conditions and completed assets at defined stages of the work.
- Early identification of constraints
Terrain, access, property boundaries, crossings and existing infrastructure can be considered before construction progresses.
Our energy and construction survey process
- Defining the project requirements
We discuss the asset, project stage, geographic extent, accuracy, coordinate system, deliverables and intended use of the survey information.
- Reviewing available information
Our team reviews design files, asset records, title information, previous surveys and other project data provided to us.
- Planning access, safety and methodology
We consider site inductions, operational constraints, terrain, landholder access, vegetation, traffic, airspace and other relevant conditions. Work near live electrical infrastructure must be coordinated under the asset owner's and principal contractor's safety requirements.
- Establishing survey control
Where required, we establish or verify a coordinated survey-control network appropriate to the project.
- Capturing the required data
Our team uses ground-based instruments, GPS, drones, aerial LiDAR or 3D laser scanning according to the agreed methodology.
- Processing and validating the information
We process the collected data, apply relevant checks and compare it with project information where required.
- Preparing project deliverables
We provide agreed plans, coordinates, models, reports or digital files in formats suited to the project's design, construction or asset-management workflows.
- Supporting later project stages
We can return for set-out, verification, progress surveys and final as-built documentation as the work advances.
Survey deliverables
Depending on the project scope, deliverables may include:
- Survey control reports and coordinate schedules
- Topographic and detail survey plans
- Corridor plans and profiles
- Point clouds and surface models

Frequently asked questions
Ideally, the surveyor should be involved during the investigation or early design stage. Early input helps establish survey control, data requirements and a methodology that can remain consistent through construction and handover.
A combination of ground survey, GPS, drone photogrammetry and aerial LiDAR may be suitable for long corridors. The method depends on terrain, vegetation, airspace, access, accuracy and the required deliverables.
Potentially, but each operation requires specific assessment. Electrical hazards, asset-owner requirements, airspace, weather, visibility and operational conditions must be considered before aerial work proceeds.
LiDAR may record some ground returns through gaps in vegetation. The result depends on vegetation density, terrain, equipment and survey methodology, so complete ground coverage should not be assumed.
We can collect agreed spatial information to support engineering analysis. Confirm whether Treasco also provides the analysis itself or supplies survey data to the responsible electrical or civil engineer.
Treasco can undertake relevant cadastral surveys and prepare plans for infrastructure easements. The process may also require landowner agreements, legal documentation and approval or registration by other parties.
Survey control is a network of coordinated reference marks used to position survey measurements consistently. It helps align design, construction set-out, contractor work and as-built documentation.
An as-built survey records the measured position and level of completed infrastructure. It may support verification, handover, certification or future asset management.
Yes, subject to confirming file compatibility, coordinate systems, revision status and required outputs. These details should be established before fieldwork or set-out begins.
Often, yes, but the work must be coordinated with the site's operational and safety requirements. Access restrictions, moving equipment, live infrastructure and obstructions may affect methodology and timing.
Files may be prepared for agreed CAD, GIS, point-cloud or modelling workflows. Exact formats, coordinate systems, attribution and levels of detail should be included in the survey scope.
