The design for the Sydney Opera House was selected from entries in an international competition held in 1956. From more than 230 designs submitted by major architectural firms worldwide, the committee selected a dramatic concept by Jorn Utzon, a Danish architect who was virtually unknown outside of Denmark. He described his work as more like a sculpture than a building because it appeared to change shape depending on the direction from which it was viewed. He was also very committed to organic principles, which dictated that the structure must fit in with the environment. Situated in Bennelong Point, a promontory that stretches into the harbor, Utzon drafted the curved roofs of the opera house to look like a sailing ship at full sail on the water.
Clearly, the roof is the most revolutionary part of the design, which was so far ahead of the capabilities of engineering at the time that Utzon had to spend several years reworking the details for the construction of the roof sails in order to help the engineers solve the problems associated with actually building them. For example, stabilizing the shells that rose almost 200 feet high presented a serious challenge. Prestressed concrete was very new in building construction at the time that it was used to make the ribbed shells for the roof. In addition, computer technology was just catching up with the complex structural calculations and models that the architect needed for his vision to be realized.By 1966, a decade after the design was chosen, the opera house was not even near completion. It was over budget, there were problems with the engineers and the contractors, and the fate of the structure was the object of political debate; Jorn Utzon resigned from the project. Eventually completed by others, by the time that it opened in 1973, it had been under construction for 17 years. The roof alone had required almost 2200 precast concrete sections, some of which weighed 15 tons, held together by 220 miles of tensioned steel cable and covered by more than a million white glazed ceramic tiles.
Sydney Opera House was a clear example of the advancement in the structural engineering in that period. It was considered as a masterwork of architecture in modern period. According to the lecturer, it remarks as a creature of the computer age and the age of high technological revolution for the artist of that period. The professor further explains the Sydney Opera House as a ship in harbour rather than a structural monument. It was way different from the organic structure completed by Frank Lloyd.
The design of the Sydney Opera House was a dramatic concept by John Utzon which was more like a sculpture than a building due to its changing appearance of shape when viewed from different directions. It took around 17 years for the construction of Opera House to get completed which was unique in its kind. It's roof alone had required almost 2200 precast concrete sections out of which some were 15 tons heavy, held by 220 miles of tensioned steel cable and covered by more than a million white glazed ceramic tiles. It was way different from a international school back then in Sydney and being designed in international skyscrapper mode, the professor classifies this building as unique.
