START
On September 13th ,1955 the contest for design of the Opera House was launched, which won Jorn Utzon -
CONSTRUCTION
After the demolition of the Fort Macquarie tram depot, construction of the Sydney Opera House began in March 1959 -
PHASE I: PODIUM CONSTRUCTION
The construction of the upper podium would begin, which will house all the people, facilities, changing rooms, bars and lobbies. With an area of 1.8 hectares, on two platforms, at 8 and 15 m above sea level. -
DELAY IN CONSTRUCTION
Construction was delayed 47 weeks to the original plan, while the budget was $ 3 million, which was not enough. -
PODIUM AND INTERIOR DESIGN
On August, the podium was completed and a year later the interior design was built. -
PHASE II: THE CEILINGS
For two years, various roofing alternatives were experimented. The original idea of parabolic surfaces was dangerous, since if one collapsed, the others would follow. Finally, Utzon devised a great solution: the covers would be made using "ribs" of a sphere of radius 75 m forming independent layers and would not successively collapse if one of them failed. -
CONFLICT
After a long conflict with the New South Wales government due to construction costs, Utzon gives up on the project and Peter Hall takes over. -
PHASE III: THE INTERIOR
Peter Hall carried out the development of the interiors of the work, changing some of the concepts of Utzon, especially in the opera room, increasing the galleries and modifying the shape of the ceiling of the concert hall. -
FINAL COST
The final cost of the Opera was estimated at 3.5 million Australian dollars, but this increased to 120 million dollars. -
INAUGURATION
It was opened on October 20, 1973, by Queen Isabel II. The opening ceremony consisted of fireworks and a performance by Symphony no.9 by Beethoven. -
FACT
