Vasse Diversion Drain Upgrade
Civil construction survey support for a 6 km flood mitigation and drainage infrastructure upgrade in Busselton, including survey control, structure set-out, machine control, UAV capture, TLS LiDAR scanning, quantity reporting and Water Corporation DS-80 as-constructed records.
The Vasse Diversion Drain Upgrade required coordinated survey support across approximately 6 km of drainage and flood mitigation infrastructure in Busselton. Noble Surveys supported Vasse Joint Venture with survey control, topographic and feature survey, construction set-out, machine control model support, UAV capture, TLS LiDAR scanning, quantity reporting and Water Corporation DS-80 as-constructed records.
Survey workflows supported construction across concrete structures, bridges, headwalls, culverts, floodgates, sheet piling, retaining structures, scour protection and access tracks. Field and office teams maintained consistent records before, during and after construction so project stakeholders could review progress, quantities and as-constructed documentation.

Scope of work
Survey coverage for Busselton drainage and flood mitigation works
Drainage construction required rotating coverage across structures, sheet piling, access tracks and open channels. Survey crews, UAV capture and TLS LiDAR scanning workflows helped workfronts reference the same control framework and model set.
- •Survey control establishment and maintenance across the 6 km drainage corridor.
- •Topographic and feature survey before, during and after construction.
- •Construction set-out for concrete structures, bridges, headwalls, culverts, floodgates, sheet pile walls, scour protection, retaining structures, access roads and maintenance tracks.
- •Machine control design model preparation, uploads/support, updates and change tracking for civil plant.
- •UAV capture for progress review, earthworks quantities and site context.
- •TLS LiDAR scanning for detailed capture of structures, sheet piling, interfaces and verification areas.
- •Earthworks quantities, surface comparisons, progress claim support and reconciliation notes.
- •As-built/as-constructed survey records prepared to Water Corporation DS-80 standard.
- •QA, conformance and drainage asset records prepared for contractor, superintendent or asset-owner review.
Survey methods & technology
Technology supporting drainage infrastructure delivery
Trimble GNSS, total stations, digital levels, UAV capture, TLS LiDAR scanning and model management workflows helped construction activities remain tied back to project control while data moved between field and office teams.
- •Trimble GNSS RTK workflows for control, set-out and pickups along the drainage corridor.
- •Trimble total station support for structures, bridges, culverts, sheet piling and higher-precision set-out.
- •Digital level workflows for vertical control, drainage grades and conformance checks.
- •UAV capture for progress review, quantity support and spatial context across the corridor.
- •TLS LiDAR scanning for detailed capture of structures, sheet piling and constructed interfaces.
- •Trimble Business Center (TBC) and Civil 3D workflows for surfaces, LandXML, DWG/DXF, PDF plans and reporting outputs.
- •Machine control files, model issue records and surface comparison workflows for civil operators.
Reporting & deliverables
Drainage documentation prepared for review
Reporting packages gave Vasse Joint Venture and project stakeholders structured evidence of set-out, quantities, DS-80 records and flood mitigation asset information.
- •Set-out records for concrete structures, bridges, drainage, culverts, floodgates, sheet piling and civil works prepared for review.
- •Topographic and feature survey data captured before, during and after construction.
- •As-built/as-constructed survey data for drainage assets and flood mitigation infrastructure.
- •Water Corporation DS-80 as-constructed records prepared for review.
- •Machine control models, LandXML files and model issue logs.
- •DWG/DXF outputs, PDF plans, point files and surface models.
- •UAV outputs for progress review, quantity support and site context.
- •TLS LiDAR outputs for detailed verification and constructed-feature capture.
- •Quantity reports, progress claim support and earthworks reconciliation notes.
- •Conformance reports, drainage asset records and structure/as-built documentation prepared for contractor, superintendent or asset-owner review.
Project challenges
Coordinating survey across a 6 km drainage corridor
Construction involved concrete structures, bridges, culverts, floodgates, sheet piling and drainage interfaces operating simultaneously. Survey teams balanced model updates, surface comparisons and DS-80 documentation while responding to environmental considerations.
- •Multiple construction fronts across a 6 km drainage corridor.
- •Concrete structures, bridges, culverts, floodgates, sheet piling and drainage interfaces requiring coordinated set-out.
- •Maintaining survey accuracy across a long linear project area.
- •Coordinating survey data capture before, during and after construction.
- •Machine control model updates, surface comparisons and design revisions.
- •Environmental constraints associated with drainage and flood mitigation works.
- •Coordination between survey crews, civil crews and machine control operators.
- •Preparing Water Corporation DS-80 as-constructed records for review.
Outcome
Survey, UAV and TLS LiDAR workflows helped the project team maintain consistent records across the 6 km drainage upgrade, supporting construction set-out, machine control, as-constructed documentation and flood mitigation infrastructure review. Quantity reporting, surface comparisons and Water Corporation DS-80 records gave stakeholders structured information for review and handover.
