Safe Design: Robust and Practical Temporary Propping of Super-T Girders

As part of the Peninsula Link Project, the project contract documents required that the designer take responsibility for the design and documentation of temporary propping supports for precast girders to discharge their safe design responsibilities.From this requirement it evolved that the designer undertook to design temporary propping to a robust standard that included mechanical restraint and design of propping for a range of load conditions above that previously adopted by the contractor in its typical temporary works design.The project comprised 45 bridges and was completed in January 2013. Across the project the form of the bridges varied and the adopted temporary restraint measures were customised to suit each specific structure whilst maintaining the initial design standard.
