Grocon contracted Delta Group to complete civil construction works for the development of a new high density, mixed use precinct comprising retail, hospitality, commercial offices and residential apartments – the $660m Queen Victoria Village or ‘QV’ building.

The scope of works included:

  • Bulk/detailed excavation works allowing for the construction of reinforced concrete foundations.
  • Concrete infrastructure – slab preparation and construction, retention systems and lift core rafts.
  • Construction of crane bases.
  • Emissions, noise and vibration controls.
  • Transport logistics, including traffic management and supervision.
  • Site infrastructure – basement stormwater drainage systems.
  • Site dewatering.
  • Removal of friable and non-friable asbestos.

With a site footprint covering 10 acres – or an entire city block – the QV project represented the largest basement excavation ever undertaken in the city of Melbourne to date. Another ‘first’ for our project team was to complete excavation works without piling retention for 90% of the site. Other key achievements included:

  • Excavation of more than 560,000 cubic metres of spoil – at a rate of more than 6,500 cubic metres per day.
  • Spraying 16,000 sqm of shotcrete.
  • 300 pad footings.
  • 2,250 ground anchors.
  • 4 lift over-runs.
