Salt Pan Creek

Client:                                    Sydney Trains (Major Works)

Consent Authority:              Transport for NSW

Project Value:                       $12m

Description

The Saltpan Creek rail bridge was a steel lattice bridge structure with timber sleepers to be replaced with new steel beams, concrete deck panels and direct fixed rail. At this location, a new concrete bridge had been constructed as part of the K2RQ project and one of the earlier steel bridges already replaced and upgraded to concrete panels. The final bridge to be replaced during a three-day possession window. The project had to contend with additional precautions due to the proximity of the Ethane Gas Pipeline (EGP) running feed product to the Botany Industrial Park. An EGP management plan was developed to protect the pipeline from damage with an exclusion zone established, in additional to steel plates being placed on the road and a 600 tonne lattice boom crane positioned at a safe distance resulting in lifts occurring with a 75m radius.

 

Scope of Service

Co-ordinated with the various team leaders representing the individual rail systems (civil, track, signaling, overhead traction wiring), to develop an integrated construction schedule for the possession period. Provide scheduling support during the possession by working with the construction teams, updating and maintaining the schedule, producing continuous status reporting and early identification of potential issues, possibly preventing the recommissioning of the track, enabling passenger services to recommence.

 

Project Outcome

The project teams, acknowledged for the delivery of a complex and difficult project within strict time constraints. The project complexity was increased by the proximity of the EPG line and its associated risks and the additional precautions required as the bridge spans Salt Pan Creek. The success of the project was acknowledged by Sydney Trains management.
