Aubin Grove Station: Perth's New Multi-Modal Interchange Project.pdf

Project Overview:

The $125 million Aubin Grove Station is a multi-modal interchange station on Perth's Mandurah passenger rail line, designed to cater to the expanding southern suburbs.

Key Features:

First island platform built within a live rail environment in WA.
2,000-bay carpark and duplication of Russell Road Bridge.
Two footbridges connecting entry buildings to island platform above Kwinana Freeway.
150m long island platform and 10m width.

Construction Details:

Contractor: Georgiou Group
Architects: MPS Architects & Coniglio Ainsworth Architects
Construction Value: $125 million
Challenges: Working between live rail lines, maintaining freeway and rail network services, ambitious construction program, critical shutdown dates, and space constraints.

Innovations & Solutions:

Early Contractor Involvement (ECI): Georgiou utilized ECI to streamline planning and reduce project timeline by 12 months.
Prefabricated Concourse Modules: 30-hour freeway closures facilitated the concentrated installation of precast concrete concourse modules using a customized lifting frame.
Modular Construction: Concurrent bridge and station works by two separate teams minimized shutdowns and risks associated with live environments.
Sand Blasting: XL Precast employed sand blasting instead of water blasting for exposed aggregate stair landings to achieve superior finish.

Key Deliverables:

Precast Walls & Stairs: XL Precast supplied precast walls, platform step-outs, and stair landings for the station.
Structural Steel Fabrication: Fremantle Steel Group fabricated and erected structural steel for the platform, concourse, entry buildings, and overpass modules.

Outcomes:

Successful delivery on budget and schedule.
No lost time due to injuries thanks to robust safety planning.
Road and rail services maintained throughout construction with no disruptions.
Positive community reception and recognition of the project's quality.
