Our Experience—Transport
Rail We know how important it is to have a well-designed rail system - it keeps our transport network running smoothly, connects regions, reduces traffic jams, and cuts down on carbon emissions. Crucial in creating a safe and reliable design solution, our expertise in route assessment, track design, bulk earthworks design, rail bridges, structural analysis, stormwater management and drainage design will ensuring your rail project achieves the project goals, making life better for everyone.
Raes Road Bridge over Rail— $32m CIVIL, STRUCTURAL AND TEMPORARY WORKS
Marion Station Pedestrian Open Underpass—$3.7m CIVIL, GEOTECHNICAL, RAIL AND STRUCTURAL WGA prepared the concept design for an 'Open Pedestrian Underpass' at the Marion Railway Station to replace an ageing and non-compliant overpass structure. The design aimed to provide an open style underpass designed using Crime Prevention Through Environmental Design (CPTED) principles to provide a safe thoroughfare for train passenger and pedestrians. The design included Earthing and Bonding of the entire infrastructure within the rail corridor, extensive CCTV cameras and lighting, vandal proof 42-inch LCD display screens at the base of each ramp which provide any user with a full view of all areas of the underpass on the LCD TV screen. The structural design including the detailing of all the fencing, balustrades and handrails were documented in 3D using REVIT software.
Aimed to facilitate access from Stockwell Drive to Kimberley Estate, WGA designed then new bridge and associated temporary works over the Bendigo V-Line railway track. WGA provided comprehensive structural design of the bridge's superstructure and substructure, on/ off structure barriers, retaining walls, approach wingwalls, and anti-throw screens. The complexity of the site demanded an integral bridge design without expansion joints, leading to intricate substructure solutions eliminating the need for specific inspection or maintenance within the rail corridor. We addressed concerns of future V-Line tracks within the cutting by foreseeing requirements for rockface spill retention and proposing slope stabilisation methodologies like soil nails or rock bolts. Notably, our design allowed the utility placement alongside the bridge for streamlined maintenance access without track closures.
Torrens Road to River Torrens— $801m CIVIL, ELECTRICAL, GEOTECHNICAL, HEAVY LIFTING, HYDROGEOLOGY, STRUCTURAL, TEMPORARY WORKS AND TRAFFIC WGA completed active rail crossings at Chief Street and Coglan Street in Brompton, SA and Queen Street in Croydon, SA. The team also contributed to the design of the Outer Harbor Rail bridge, which was constructed in a constrained site along the existing rail alignment. The design of the rail bridge embankments used a combination of precast retaining walls and in situ bored piles able to be installed during low-speed operating conditions. A critical innovation, this ensured completion of the rail embankment and rail bridge within a 20-day track closure window. Careful consideration to the compaction regime for earth fill behind the retaining walls was required to balance the competing requirements to minimising precast wall size and hasten construction. WGA designed the temporary works and undertook the heavy lifting design required for the safe installation of the superstructure of the new rail bridge.
Goodwood Junction Rail Grade Separation—$45m CIVIL, GEOTECHNICAL, STRUCTURAL AND TEMPORARY WORKS The Rail Grade Separation project removed a major bottleneck in the Adelaide Rail Network by separating the Australian Rail Track Corporation freight and Belair Passenger Rail line from the twin track Seaford Passenger Rail line, removing the existing at grade conflict between the freight and passenger lines. Through the design and construction of a 550m underpass separating the freight and passenger rail lines, the project facilitated the removal of a road level crossing at Leader Street, and a rail diamond at Goodwood. WGA delivered hydraulic modelling and engineering design for the diversion of Brownhill Creek culvert around the rail underpass. In addition, the team led the geotechnical design of the revetment walls, and detailed design of all temporary works, including structures, pavements, and drainage.
Oaklands Level Crossing Removal - Concept Design— $110m CIVIL, STRUCTURAL AND TRAFFIC WGA prepared the concept planning for the Oaklands Rail Grade Separation project. The project removed the level crossing by lowering the Seaford rail line underneath Morphett Road, including a lowered Oaklands Railway Station. WGA undertook the traffic modelling for the project to support the business case, and prepared concept road, rail, pedestrian crossings, rail station concept and bridge structure designs for the project.
