Water Corporation Drainage Works at Bayswater Station Rail Viaduct

The Morley to Ellenbrook Line project is part of a staged initiative targeting improvement and integration of transport options in Perth's north-eastern corridor. The project aims to deliver approximately 21km of rail infrastructure and ancillary works to support operational passenger rail between Bayswater and Ellenbrook. It includes design and delivery of five stations including intermodal bus and rail, with parking and associated roadworks at Morley, Noranda, Malaga, Whiteman Park and Ellenbrook stations, and ancillary works at the Bayswater Station.

FSC's Role

 FSC Civils was engaged to perform water corporation drainage works as part of the Baywater Rail Viaduct project.

Key Challenges

• Delays in start due to Design Issues and Scope Changes
• Pending APRA approvals and Dewatering for Open Drain Works
• No crane access for lifting pipes and shoring boxes underneath the bridge
• Little Room to work underneath the bridge.
• Retaining soil with Old Pit connection while excavating

Outcomes

Despite pending approval delays from APRA, FSC successfully delivered the project within the designated timeline.

To address dewatering challenges, dewatering pumps were deployed effectively.

Restricted access conditions prevented the use of a crane beneath the bridge; however, FSC adapted by utilizing a 49T excavator to lift shoring boxes and pipes, ensuring the job was completed.

Connecting new pipes while retaining soil around the old pipe connections posed a significant challenge, but FSC managed this by excavating in layers and installing the new pipes in stages, preventing soil collapse.

Overall, despite numerous obstacles, the project was a success and delivered on schedule as per the project timeline.”

North Link Stage 3

The Northlink Stage 3 Project involves the construction of a free-flowing dual carriageway between Ellenbrook and Muchea, resulting in a fit-for purpose section of this national highway with four lanes taking most of the heavy traffic away from Great Northern Highway.

FSC's Role

FSC were awarded a Contract to complete a drainage package which involved placing of Pit & Pipe, construction of insitu reinforced concrete culvert bases and headwalls and placement of precast box culvert units. FSC’s ability to adapt quickly and supply versatile skilled trade labour has been rewarded with multiple additional packages of work being added to our contract including supplying skilled labour to complete FRP works on 4 bridges.

Scope of works

• dual-carriageway between Maralla Road and Muchea
• interchanges at Stock Road, Neaves Road and Brand Highway
• deviation at Brand Highway
• flyovers at Muchea South Road, railways and Ellenbrook

Metronet – Thornlie Cockburn Link & Yanchep Rail Extension

METRONET’s Thornlie-Cockburn Link is Perth’s first east-west rail connection, servicing the communities between the Mandurah and Armadale lines. The Thornlie-Cockburn Link is being built within existing rail corridors requiring a number of changes along the alignment including: - Relocating the freight lines to the northern half of the corridor to make room for the passenger lines in the southern half. - Replacing the Cameron Street-Elliot Place pedestrian level crossing with a footbridge over the rail for safer access. - Modifying the Ranford Road and Karel Avenue road bridges to accommodate the extra set of track and meet safety standards.
