Point Wilson Bridge Lift

CDSE Consulting provided critical Technical Advisory Services which contributed to the successful lift of the Point Wilson Bridge over the Princes Highway in Victoria’s south-west.

Key Services

Assisting G&G Engineering with the successful tender for these works, coordinating and pricing the Temporary Works scope

Conducting site inspections to assist in developing the lifting methodology concept, and a condition report following completion of the lift

Coordinating the temporary works design, with the Lead Designers – Robert Brid Group, and Proof Engineers – WGA

Onsite quality assurance during the installation of the temporary works and during the lift

The Project

CDSE Consulting was proud to work with G&G Engineering, in conjunction with Fulton Hogan, the Department of Transport and Planning, and many other stakeholders and participants, to successfully raise the height of the Point Wilson Bridge by 200mm, to reduce the risk of the bridge being hit again, following two recent impacts in 2010 and 2018. The 304-tonne bridge superstructure was raised using hydraulic jacks to synchronously lift all beams from temporary supports at both abutments and all four piers.

Our Involvement

CDSE provided crucial engineering input in the development of the Temporary Works design, throughout the works onsite, and also provided surveillance during the lift itself, coordinating with the hydraulic systems operator and the work crews to ensure that maximum weights weren’t being exceeded on the propping system, and any challenges during the lift were quickly addressed and rectified.

The End Result

The bridge lift was highly successful, with completion occurring within five minutes of the planned time. Overall, public disruption was minimised though effective coordination with traffic teams, ensuring that the road was reopened quickly once each staged lift was completed.

The structure was inspected by CDSE before and after the lift and the condition of the structure was found to be unaffected by the lift works, demonstrating that the methodology and execution of works was well considered and completed.

These works have provided a more accessible Princes Freeway, ensuring all vehicle sizes can travel to Geelong or Melbourne safely without fearing their heavy vehicle will hit the bridge.
