Northlink Stage 2 Project

  • Client:
    Monford Group / CPB Contractors for Main Roads WA
  • Location:
    Reid Highway to Ellenbrook
  • Project Type:
    Link to Perth’s North-east Corridor

Project Overview


Alliance Surveying was engaged to deliver precision surveying services for Northlink WA Stage 2, spanning from Reid Highway to Ellenbrook. This section of the project formed a critical link in Perth’s north-east corridor, designed to reduce congestion, improve road safety, and provide a direct freight route.

Our licensed surveyors led a skilled team of professionals to support every phase of the project. With a focus on accuracy, compliance, and efficient delivery, we ensured the surveying requirements were met to Main Roads WA specifications and seamlessly integrated into the wider Northlink WA program.


Key aspects of the project include:

Scope & Responsibilities

Our scope of work included:

  • Establishing survey control networks along the corridor.
  • Road alignment set-outs for new carriageways and interchanges.
  • Detailed topographic surveys for design teams.
  • Surveying for bridges, culverts, and retaining walls.
  • As-built verification surveys to confirm compliance with engineering designs.
  • Provision of digital deliverables for integration with the project and BIM systems.

Challenges & Solutions

Stage 2 presented challenges due to the project’s length and the need to maintain traffic flow during construction. Our team coordinated closely with contractors to manage surveys safely in live traffic environments.

We delivered outputs with fast turnaround times, typically within 48 hours, supporting timely decision-making and construction progress. Our fixed pricing agreements gave the client certainty, while mobilisation within 7 days of approval ensured we were on site when needed.
