PROJECT NOTES

Peritas Consulting were engaged initially by the Swan River Pedestrian Bridge Alliance to provide construction engineering design to assist in the installation of the bridge steel wishbone arches.

 

The proposed installation method, using a hydraulically controlled tuning brace between the wishbone ends was considered impractical.  Peritas designed a far simpler (and cheaper) method of adjusting the tuning brace, shop detailed the members and assisted the contractor in the procurement of the necessary materials.

Peritas also designed a temporary landing nose to be fixed off the concrete abutments to receive the ends of the wishbone arches from the installation barge.

Following this work, Peritas was engaged by Main Roads WA to complete a 3rd party verification of the lifting methodology of the arches, and complete reviews of the jacking strand plates using FEA analysis.
