Shamrock Civil Engineering was awarded the contract to construct a pad for a future concrete batch plant in Portion A, near Maclean, as part of the Pacific Highway Upgrade – Woolgoolga to Ballina Project. Shamrock Civil Engineering were also required to construct an access track to the new pad, which was to provide access to the batch plant site for Pacific Complete and its contractors.


Scope of Works

  • Earthworks including 21,000m3 cut and 17,000m3 fill resulting in a 4.5m high batter at one edge of the site
  • Box out access track alignment, placement of select material, placement of roadbase and various swale drains to facilitate drainage
  • Drainage works including swale drains adjacent to the access track, as well as various sumps and batter chutes to control storm water run-off
  • Fauna fencing in selected locations, as well as final stabilisation of the finished batters and drains, through the use of soil binder, hand seeding and jute mesh



Shamrock Civil’s project team faced several environmental challenges throughout the project, including:
  • The management of sediment and erosion control in a high risk environment, with steep batters, as well as during a period of heavy rainfall
  • Protecting nearby sensitive flora and fauna in an environmentally sensitive area throughout the construction phase
Despite the above challenges, Shamrock Civil was able to deliver these works with zero safety or environmental incidents, whilst achieving the client’s environmental objectives. Shamrock was able to achieve this by working collaboratively with the client’s environmental team and instilling a strong sense of environmental responsibility in the work force.
