Lake Raeside Bridge – the bridge cantilever was provided by using Paraslim and deck from Web Tie
The existing Lake Raeside Bridge located on the Great Eastern Highway, near Leonora, in Western Australia was a single span bridge, which was subject to flooding and consequently deemed not fit for its purpose.
The commencement of construction of the new 5 span bridge started in September 2008 and was completed in May 2009. Its design is the concrete pier and abutments style of bridge construction, with an insitu concrete deck poured on top of structural steel beams.
Due to the remote nature of this project Formaction Concrete Civils required a company that could provide all of the formwork and scaffolding solutions and that is why they decided to use RMD Australia.
The Web Tie and Paraslim Systems
The most significant aspect of the project was the soffit system used for the insitu concrete deck pours. The Web Tie and Paraslim systems provided a solution that was not reliant upon traditional shoring methods erected from the ground. The system also provided a quick strip option via lowering the soffit in sectionalised tables to the ground. NB: please obtain further details about these products by clicking on Web Tie or Paraslim.
Also side forms were supplied
RMD also provided the side forms for the pier footings, abutments, headstocks and bridge forms utilising Super Slim Soldiers, Alform Beam, LVL Timber and ply.
The circular columns were formed utilising RMD SuperTube Plus sacrificial column forms. Temporary support to the structural steel beams was provided during construction by utilising the Rapidshor shoring system in a 3m x 1.8m grid.
