Construction of a new 52.2m long, 3 span precast plank and cast insitu concrete deck bridge across the main Hunter Valley Railway, including 400m of new road embankment and bridge approaches, local road formation and associated intersection improvements, as well as relocation of existing power, Telstra, water and sewer assets.

With over 160 trains a day and nearly two million tonnes of coal a week passing through the site, the ability to work to the set rail possession shutdowns and ensure protection of rail operations was paramount, as any impact to train schedules would have incurred massive penalties in excess of $15,000 per minute to the network and coal chain.

The project team developed stringent safety measures and sophisticated programming to ensure safety of all workers and rail staff, as well as minimal delays to rail operations.

Adequate contingencies were planned to allow for delayed granting of rail possession due to late freight trains and forecast heavy rain. All works were successfully completed to plan well within the allowable time frame with access handed back ahead of time.

“Seymour Whyte has responded very positively to the delayed possession of site, demonstrating a proactive approach to maximise its productivity”
