Engenium’s Newcastle office was recently engaged as the engineering design and drafting consultant to support Civmec’s heavy engineering fabrication division for the Nepean River Pedestrian Bridge – Australia’s longest single span pedestrian footbridge.

The scope was to design, model and provide shop detail drawings for the temporary works that would be used to fabricate the bridge structure during construction.

The temporary works were required to operate under high loads at elevated heights, as well as having tight geometric constraints dictated by the bridge geometry and the construction technique.

The steel fabrication temporary works design played a critical part in facilitating the innovative construction technique employed on the project, which required growing the bridge by the welding of prefabricated sections at the same time that the bridge was deployed over the Nepean River.

The Newcastle team delivered several smarts to reduce man hours and minimise costs for the client, including winched pulley systems as a low cost replacement for hydraulic drive systems and the use of existing building foundations to help reduce construction time.

Integrated 3D modelling for clash detections allowed the effective elimination of fabrication rework for the temporary works for all standard construction sequences.
