Project Description

The Perth Airport has been undergoing major developments as part of the Forrestfield-Airport Link project. A key feature of the project is the new skybridge which connects the Airport Central train station and the airport terminal. The $31 million, 280-metre enclosed skywalk provides passengers with a sheltered walk while also giving visitors a 15-metre high platform to view the airport surroundings.

Working with the Perth Airport and Georgiou Group, Abaxa was commissioned to provide a full site evaluation prior to construction. The project began with a desktop utility assessment (including the Perth Airport GIS) to gather data for a site inspection. Next, was a detailed site survey to validate and verify utility records and detect the subsurface infrastructure.  

Working in a fully operational airport (pre-Covid19) provided a challenge. However, having previously worked on major city projects in high populated areas, including Elizabeth Quay and Perth City, Abaxa was well versed operating in public areas.    

The subsurface assessment identified several unplanned utilities, including some outside the approved clearance areas. Collaborating with the project manager, Abaxa provided recommendations for construction in line with their Safety Management Plan. The result was a reduced risk of asset damage and a completed field investigation which complied with Australian Standard AS5488.

Providing crucial data on underground utilities avoided any unplanned delays and allowed a seamless delivery of the new Perth Airport Skybridge.

Replace & Upgrade Cast Iron Reticulation Project

The project required a Utility Survey to identify, locate utilities and complete a site features and utility survey to support engineering final design in a replacement plan for water mains constructed more than a century ago in Fremantle. The replacement of water mains was scheduled by the Water Corporation from August to October 2019.

Freeway Modification Design & Construction Project

For this project, Abaxa was involved with Perth’s first Smart Freeway including creation of an additional lane from Canning Highway to Narrows Bridge. The Smart Freeway will use smart technology to open and close traffic lanes in the event of an incident and adjust speed limits to get more traffic through during busy periods.
