Scentre Group engaged Delta Group to deliver a challenging and complex integrated Early Works programme to drive a $300m transformation of the historic David Jones building into a luxury retail precinct in the heart of Sydney CBD.

Our scope of works included:

  • Hard and soft strip out
  • Temporary Works engineering and design – structural steel retention of heritage listed facade
  • Asbestos and Hazmat identification and removal
  • Heritage salvage and protection of 500 items including awnings, subway tiles, lift indicators, travertine
  • Decommissioning and removal of 16 escalators and 8 lifts
  • Accelerated local demolition for tower crane, alimaks, driveway entrance, construction decks
  • Excavation of pads, strips, overruns, crane and alimak bases

Unique to this project was its high profile and restricted/congested location between Hyde Park and Pitt Street Mall, as well as an accelerated programme to accommodate delays incurred during the COVID-19 Pandemic. With an 80 year old heritage listed facade requiring extensive protection/retention systems, bespoke methodologies and fabrication techniques were successfully employed to connect new and old steel.

Other challenges of the accelerated programme involved significant client and developer involvement/liaison; multiple large crews across 15 different floors and interface between contractors;  strict environmental controls – noise, vibrations and dust; and extensive traffic management planning and key stakeholder engagement.

Key project statistics included:

  • 95,000 work hours
  • Total 110 workers at peak – including up to 32 different trades/consultants
  • 3000t C&D waste from retail and commercial strip out
  • Installation of 550t of structural steel to retain heritage facade – including installation of 700+ pieces of steel
  • Removal of 28,500m2 of lead paint
  • 1800m3 of bulk/detailed excavations – 3,700t of sandstone
  • 6,000t of steel and brick recycled
  • 1,700+ vehicle movements
