Deer Park Bypass

​Delta was contracted by the Baulderstone Leighton Regional Railway Joint Venture (BLJV) back in May 2013.


Project Overview

Delta’s scope was to tunnel under the Deer Park Bypass to allow for the construction of the railway tracks from the Deer Park train station to the recently constructed Tarneit Train station.

Our detailed scope included;

  • Bulk Earthworks
  • Tunnelling exaction works
  • Detailed Earthworks
  • Supply and installation of Soil Nails (in backfilled Roadway material),
  • Installation of Shotcrete Concrete Spray Walls,
  • The construction of the Deflection Wall (to protect the Pile from a train derailing event)

The minor drainage works which included strip drains behind the shotcrete and deflection walls and the spoon drain on top of the shotcrete wall.

All construction methods, materials, testing and QA had to be as per the Vicroads Standard as a minimum.
