The project was to provide the best value replacement and remedial works for six railway bridge superstructures. The new durable superstructures were to have minimal maintenance requirements during the service of their life.

The Project

The project consisted of a superstructure replacement of the following steel under bridges:

  • Penguin Creek Bridge - approximately 37 m long and 3.0m high with 5 spans of varying lengths
  • Roland Street Bridge - a single span simply supported structure with an approximate span of 5.0m
  • Muddy Creek Bridge - a two span simply supported structure with an overall length of 9.0m
  • Hellyer River Bridge - an eight span simply supported structure with an overall length of 24.5m
  • Four Mile March Creek Bridge - a single span simply supported structure with an overall length of 3.2m; and

Superstructure replacement of the following timber overbridge:

  • Violet Banks Bridge - an 18m long and 5.5m high bridge with 3 spans of approximately 5.8m

Timeframes

Time frames available for construction were tight, between 8 to 20 hours.

VEC had to ensure that no construction works interfered or delayed the operations of the TasRail commercial train operations. To ensure this risk was minimised VEC had to arrange constructions windows for removal and replacement of each of the railway under bridges within the TasRail timetable.

VEC, in conjunction with their designer, came up with a design for all pre-cast components which “bolted” together on site. This along with being able to stock pile all the components on site before the occupation ensure the work was completed within the timeframe.
