Project Notes

Peritas were engaged by Georgiou to undertake the lifting design for the new Perth Airport Skybridge, linking the Forrestfield Airport Train Station to the International Terminal.  The Skybridge comprises 12 steel modules, the largest of which is 32m long, 8.5m wide and 83T and needed to be lifted in over Horrie Miller Drive during a limited shutdown window.  Careful consideration of the lifting methodology was also required due to the ceiling heights on the lift imposed by the Airport due to its operations.

Peritas designed a series of lifting frames for the modules, based on both single and dual crane lift arrangements.  The frames were slotted through the top chords of the skybridge truss with the lifting pins designed to be removed via lever from within the module.  This enabled the Contractor to lift the modules with the roof cladding, gutters and capping installed, whilst factoring in the safety of the workers.

The performance of the modules during the staged installation was also considered, with temporary propping design provided where necessary to control deflection and maintain the intended performance requirements of the completed structure.  This was completed in co-ordination with the Skybridge design engineers.
