Eneabba Terminal 132/330 kV Upgrade
Construction survey support for Catalpa on the Eneabba Terminal upgrade, part of the Clean Energy Link North program, including control, earthworks modelling, civil and bolt set-out, UAV progress capture, quantity verification and conformance reporting.
The Eneabba Terminal upgrade adds 132 kV and 330 kV infrastructure at the existing terminal near Eneabba as part of the Clean Energy Link North (CELN) program, which upgrades the transmission network north of Perth into the Mid West. Noble Surveys supports Catalpa with control network management, clearing and earthworks support, civil and bolt set-out, UAV progress capture, quantity verification and conformance reporting.
The scope follows the approach used on the Regans Terminal civil works, another CELN terminal. Crews work drive-in drive-out from our Perth and Bunbury offices, with mobilisation and reporting aligned to Mid West project requirements.

Scope of work
Survey coverage for terminal civil works
Noble Surveys provides construction survey support across the terminal upgrade, from early clearing pickups through to bolt set-out and regular UAV capture so the construction team keeps clear visibility of progress.
- •Control network establishment and maintenance across clearing, earthworks and terminal workfronts.
- •Clearing and topsoil survey support aligned to environmental and project recording requirements.
- •Earthworks modelling, surface comparisons and volume calculations for civil crews.
- •Construction set-out for civil works, terminal infrastructure and underground services corridors.
- •High-accuracy bolt, blinding, formwork and concrete set-out to keep structural works aligned.
- •Quantity and claim verification with notes for superintendent review.
- •Regular UAV flyovers capturing orthos, DSM/DTM outputs and progress imagery.
- •Pre-pour and post-pour survey reporting plus bolt conformance packs prepared for review.
Survey methods & technology
Survey technology used on the project
Field crews combine Trimble GNSS, total stations and UAV capture so every construction activity works from the same survey dataset, referenced to the same project control.
- •Trimble GNSS base stations and RTK rovers for resilient control coverage.
- •Trimble total station workflows for close-tolerance set-out across terminal civils.
- •UAV capture aligned to project control for progress, volume and claim reporting.
Reporting & deliverables
Evidence for superintendent and commercial teams
Reporting packages give Catalpa clear quantity data, conformance checks and documentation prepared for review, aligning with the workflows defined on the as-built surveys and UAV surveys services.
- •Regular reporting summarising set-out, capture focus and upcoming requests.
- •Quantity verification reports and supporting summaries tied to project control.
- •Pre-pour and post-pour reports with elevations, offsets and conformance notes.
- •Bolt conformance reports documenting checks against design tolerances.
- •Earthworks reporting, volume comparisons and UAV-derived progress imagery.
- •Clearing and topsoil reporting to evidence removal stages and stockpile locations.
Project challenges
Managing complexity on a terminal upgrade
We work alongside the construction team to sequence control, fieldwork and reporting so set-out windows, existing assets and concurrent trades stay coordinated.
- •Upgrade works at an existing terminal, with new 132 kV and 330 kV infrastructure built alongside live assets.
- •Overlapping clearing, earthworks, concrete and terminal scopes on a tight construction program.
- •Remote Mid West location, with drive-in drive-out survey crews planned around site access and inductions.
- •Coordinating survey records, QA notes and conformance packs across civil, concrete and terminal workfronts.
Approach
The project is ongoing. Regular reporting, conformance checks and quantity verification give the project team clear records across earthworks, concrete and terminal construction, using the same workflows proven on Regans Terminal.
