Stormwater Drainage & Electrical Work:

Daracon chose Subterra Civil to carry out stormwater drainage works on Sydney Metro Northwest near Bella Vista Station.  Works were carried out between January 2017 and June 2017. 

The contract consisted of:

  • Excavation over 4000m3 of rock
  • Installation of 36 precast pits
  • Installation of 1.5km of stormwater drainage ranging from 375 up to 1200mm

Works were carried out in the narrow corridor linking the underground tunnel to the new railway viaduct that was under construction.  

Challenges were keeping access open throughout the works and keeping the groundwater under control. As a variation to the contract Subterra Civil were awarded 1.7km of subsoils.
