Project Overview
Alliance Surveying was engaged by Monford Group and CPB Contractors to deliver comprehensive surveying support for bridge infrastructure on Stage 3 of the Northlink WA project. This phase of the state-significant transport upgrade focused on constructing multiple bridges and associated road infrastructure between Morley and Ellenbrook, transforming northbound connectivity across Perth’s growing outer suburbs.
Our projects were led by licensed land surveyors and supported by our broader in-house team of field staff and technical professionals. Together, they provided full surveying services for critical structures, including bridge piers, abutments, noise walls, and safety barriers. Working within live traffic environments and complex work zones, we ensured every component was constructed to design with millimetre accuracy, supporting safe and efficient delivery of this essential road infrastructure.
Key aspects of the project include:
Scope of Works
Alliance Surveying’s role included:
All works were completed under strict Main Roads WA specifications, with daily coordination across multiple contractors and service crews.
Challenges & Solutions
- Multi-staged urban delivery: We operated within constrained road corridors alongside live traffic, scheduling our works around lane closures and traffic switches.
- Complex structural sequencing: Multiple bridge types and variable alignments required customised survey solutions and seamless data transition across stages.
- Tight delivery timelines: With project sequencing reliant on accurate set-out, our fast mobilisation and real-time data updates helped maintain the construction program without delays.
Our ability to work closely with Monford, CPB, and Main Roads WA ensured survey data was integrated into construction workflows, minimising rework and supporting structural quality assurance.
