How to ensure the project is delivered in accordance with the contract?

The Federal and State Governments provided $1.02 billion to construct NorthLink WA, linking to Gateway WA and service regional traffic movements to commercial and industrial areas such as Malaga, Kewdale, Perth Airport and the Perth CBD. As with all major infrastructure projects of this size, scale and complexity, Government and financiers needed the highest level of assurance that the project would be delivered according to the design and construction contract.

Independent Assurance ensures the appropriate level of confidence

APP, supported by partners Arcadis and SMEC, provided delivery services as Independent Certifier for the Southern, Central and Northern sections of Perth’s largest road infrastructure project. The route offers a vital, state-of-the-art transport link to reduce travel times and congestion.

NorthLink WA comprises the upgrade of Tonkin Highway to freeway standard and construction of a new highway to Muchea. A series of freeway interchanges and flyovers has improved traffic flow, and a 4 metre-wide cycling and pedestrian shared path extends along the entire route. APP and their JV partners had numerous obligations to meet, with their key roles being to undertake design reviews to assess that the design meets with the requirements of the SWTC, auditing of the contractor’s management plans as well as full time site supervision to monitor the quality of the product delivered.

Providing certainty for Government

As Independent Certifier APP, Arcadis and SMEC combined specialist technical skills and project management expertise to provide Government with the independent certification needed for major transport infrastructure projects.

Completed in late 2019, NorthLink WA provides efficient and safe road access for all road users, by eliminating four of the State’s most dangerous intersections. Importantly, the State will also reap significant productivity benefits to the economy, industry, motorists and local communities.
