BHP contracted Delta Group to complete major industrial demolition works at its Nelson Point facility in Port Hedland, Western Australia. In particular, the demolition of a Tertiary Crushing Building (TCB02) and Transfer Station (TS204).

The scope of works included:

  • Demolition of existing TCB02 and TS204 structures including foundations.
  • Engineering study, including 3D modelling for proposed demolition methodology.
  • Emissions, noise and vibration controls.
  • Protection of adjacent structures.
  • Onsite processing, removal and transport of construction/hazardous waste materials.
  • Traffic management and supervision.
  • Civil demolition & backfilling of all excavations, disturbed land or voids.

To complete the demolition works programme and to ensure no disruption to the surrounding Nelson Port operations, we devised an innovative methodology comprising 4 controlled, sequential fells with weights in excess of 580t each. A range of plant such as substations, conveyors and access ways were located within 500mm of our work and our vibration control measures were implemented without disruption.

We also custom designed a highly effective and efficient recycling works programme to process more than 99% of all construction waste accumulated/generated onsite – diverting waste from landfill and optimising our client’s sustainability practices.

Our innovative programme was recognised with a nomination in the 2015 World Demolition Awards (short-listed) and the 2016 Infinity Awards (highly commended).
