Lendlease contracted Delta Group to design, develop and deliver a single source project management solution to kick-start the development of Australia’s first and largest fully integrated convention, exhibition and entertainment facility – the $1.5b ICC Sydney development.

Over the 2 year life of the project we provided turnkey services for demolition and civil construction works, recycling, landscaping and the removal of asbestos and hazardous waste.

Due to the high profile of the project we operated under intense public and media scrutiny and our ability to effectively engage and manage a diverse and challenging mix of key stakeholders was critical to our success.

In particular, we undertook major demolition and civil excavation works in a constrained, high density CBD location adjacent to Sydney Harbour and without disruption to residential amenity and ambience, high volume pedestrian traffic throughout the Darling Harbour precinct, major arterial transport thoroughfares, or commercial business, retail and hospitality operations – all located within close proximity of the site.

Other key achievements included:

  • Safe remediation and removal of asbestos and hazardous waste.
  • Major structural demolition of 200,000 sqm floor area within 16 week timeframe and involving more than 20 excavators (2t – 70t) – including long reach plant to work at a height of 40 metres.
  • Integrating commercial and industrial demolition techniques for steel and concrete/brick structures – including unique collapse methodology for the 300t Convention Centre roof and demolition of Exhibition Halls on top of a suspended concrete slab.
  • Heavy structural lifts – single and dual – involving 30-40t (plus) loads on suspended slabs or in limited headroom areas underneath a major arterial road network (Western Distributor).
  • Maintaining effective emissions, noise and vibration controls – including custom fabrication of a demolition screen, specialised misting plant, steel plates, innovative cut and lift techniques and slab deconstruction practices, exclusion zones, and temporary bridging platforms using site won spoil/aggregate.
  • Installing and managing ground water treatment systems for discharge and sediment control, as well as continuous dewatering for substantial ground water tidal flows and the creation of dedicated sediment ponds.
  • Achieving our goal of recycling 98% of all construction waste materials – including the use of conveyors to move materials within confined areas, 100,000t of concrete (48,000t crushed onsite) and 16,000t of scrap steel.
  • Completing our civil works programme within 9 months – including more than 85,000 cubic metres of bulk and detailed excavation, identification and pile proof digging for obstructions, set and installation of piling mat and haul roads, and trimming of 830 piles.
  • Set out and installation of 1,000 sqm of façade cladding for the new Exhibition Centre structure.
  • 5,000 cubic metres of FRP concrete foundations, as well as 25,000 sqm of FRP structural concrete slabs.
  • Set and installation of 1,000 sqm of reinforced earth precast panels (with artwork).
