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
