An internationally recognised symbol of Australia, Sydney Opera House exemplifies the type of large, technically complex projects undertaken by the Baulderstone Group. Architect Jørn Utzon's original design was so bold that the structure was deemed impossible to build. Utzon eventually altered his design, giving the roof vaults a defined spherical geometry. This enabled the structure to be built in precast elements, greatly reducing both time and cost.
When M.R. Hornibrook Pty Ltd (which merged with Baulderstone in 1985) commenced the construction of the roof shells in 1963, the company inherited a completed podium structure that was specified before the shells were even designed. This meant Hornibrook's first task was to modify the podium to accommodate the final design for the more stable, heavier roof shells. From this beginning, the company's team had to develop the best methods to construct the unique shells.
The enormous challenges in construction demanded pioneering applications of many new materials as well as building and engineering practices. Officially opened by Her Majesty Queen Elizabeth II on 20th October 1973, Sydney Opera House has almost 1000 rooms including four main auditoriums, five rehearsal studios, four restaurants, dressing rooms, administrative offices, plant and machinery areas.
