50th anniversary

extensive heritage interface


With the Sydney Opera House approaching its 50th anniversary, the suspended slab forming the ceiling for the cafés and bar on the lower concourse, was showing its age and the waterproofing was in desperate need of an upgrade. Whilst the forecourt pavement had been replaced in some areas, the area over this suspended slab had yet to be replaced and was now a trip hazard.

Engaged, under a D&C contract, Seymour Whyte successfully removed (and repurposed off-site) the existing rough sawn granite setts, demolished the existing concrete paving substructure and waterproof membrane, installed a new waterproofing system, paving substructure and new smooth sawn granite setts.

The Sydney Opera House is an UNESCO World Heritage Listed site that holds historical, architectural, technical, social and associative significance. Working within such a high profile and trafficked precinct, the team successfully factored in all heritage, accessibility, sustainability, and maintenance considerations with zero access issues, safety incidents or noise complaints received.
