  • Project Type:
    Road Realignment
  • Timeline: 2013

Project Overview


Alliance Surveying was engaged to deliver surveying services for the Marble Bar Road realignment near the Roy Hill Mine, managed by ERTECH for Main Roads Western Australia. The realignment was critical to improving road safety, accommodating increased traffic volumes, and supporting the region’s mining operations.

Our licensed surveyors, supported by skilled field staff and technical personnel, provided accurate surveying across all phases of the project. Precision and compliance with Main Roads WA specifications were central to ensuring the re-aligned road corridor was constructed safely and efficiently.


Key aspects of the project include:

Scope & Responsibilities

Our responsibilities included:

  • Establishing survey control networks along the project corridor.
  • Road alignment and re-alignment set-outs for construction teams.
  • Surveying for drainage, culverts, and associated civil works.
  • Topographic mapping and cross-sections for engineering reference.
  • As-built verification surveys to confirm compliance with design.
  • Delivery of digital data compatible with Main Roads WA systems.

Challenges & Outcomes

The project presented challenges around remote Pilbara conditions, safety in live traffic environments, and coordination with multiple stakeholders. By working closely with ERTECH and Main Roads WA, our team ensured safe surveying practices while meeting tight project schedules.

We supported progress with fast turnaround deliverables provided within 48 hours. Our fixed-price model gave financial certainty, while 7-day mobilisation allowed our team to quickly deploy and integrate with the construction program.
