Key Aspects

Freyssinet initially planned to use a Synchronous Lifting System to jack the whole structure, one end at a time. However, upon inspection of the superstructure it was not possible to perform synchronized lifting due to the low standard of the bridges initial construction and out of plane deck units. For this reason, Freyssinet used the load transfer method using flat jacks to change-out bearings and concrete/mortar plinth under live open road conditions.
During the jacking of the structure, new lateral restraint system was installed for each abutment headstock. Once lifted, defective pot bearings were removed and replaced with new ones designed and manufactured by Freyssinet.

Schneider Road Bridge is located at Schneider Road, Eagle Farm, Brisbane, Queensland. It was designed by Cardno in 2006 and was built by a contractor on the same year. 

An inspection was carried out in 2013 by Cardno and discovered the defective pot bearings at the abutment. Another inspection was undertaken by AECOM and found the concrete spill-out a the northern abutment which has seriously weakend the articulation of the deck. 

With these defects found on the bridge, Brisbane City Council instructed the replacement of 40 units of bridge pot bearings and removal of concrete at the northern abutment to free up the articulation of the bridge.
