Melbourne Metro Train.

From level crossing removals to platform reconstructions, Greater Melbourne train stations undergo transformation.

Under the Victorian State Government’s Level Crossing Removal Project, train lines around greater Melbourne will see the removal of 75 dangerous and congested level crossings and the construction of a number of new train stations. Studco has proudly played a prominent role in this expansive project; forty-six crossings have been completed to date with the remainder due to be completed by 2025.

The ambitious project requires creative thinking to complex building problems on a number of fronts. Studco is pleased to have collaborated closely with main contractor John Holland and the Major Transport Infrastructure Authority for solution engineering and value engineered designs. This applied to a number of lightweight framing systems for facades, walls, external ceilings, and concrete wraps at the new train stations.

The external ceiling and façade wraps lining the underside of the elevated concrete train line structure proved to be one of the most demanding aspects of the program. The original design involved extensive structural steel framing - not only cumbersome and difficult to manoeuvre but more costly than a lightweight framing solution. A method was needed to replace the heavy structural steel with a more cost-effective, user-friendly framing system. This task was left in the trustworthy hands of Studco’s in-house structural engineering team.

The design have to withstand the extreme environmental forces of wind and weather. Not only this, but also the dynamic forces and significant vibration imposed by train movement along the line. In order to find a solution, Studco curated framing options through 3D models to our client’s exact specifications. Balancing short and long-term considerations – and everything in between - finite element analysis was used to pinpoint potential issues. Expansion joints were strategically placed and slip joints were provided in all three axes. The result was defined by:

• Reduced construction time
• Optimum performance
• Tangible cost-savings

The interface between the lightweight steel system and the precast concrete structure of the elevated train line required a delicate touch so that the anchor fasteners did not compromise the structural integrity of the concrete. In co-operation with Hilti, a number of anchor solutions were physically tested by an independent body to ensure compliance and durability.

Studco’s Technical Team consists of professional engineers, CAD modellers and experienced site personnel who offer a comprehensive design service and the very best technical support. We provide a full structural engineering service for lightweight metal framing solutions, in accordance with relevant Australian Standards and the National Construction Code, and with the necessary certification.
