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.
The author discusses about the architectural finesse of the Sydney opera House and states the history behind the structure of it .The lecturer is fascinated by the architectural granduer of the sydney opera house which was designed by Jorn Utzon a Danish architect.The lecturer describes the opera house as a master work of architecture which is unique on its own.The roof which is a revolutionary design is categorized as modern yet not in accordance to the international standards of architecture with respect to the lecturer.Moreover the use of newer materials and the clean geometric lines beautify the structure of the opera house.However it defies the modern architectural standard of skyscrappers , still the design looks aesthetic enough which pleases the human eye.The lecturer states that the design is high tech and a creature of the modern computer age as the computer technology was just evolving to match up with the intricate structural calculations to help visualize the model.The blend of art and architecture makes the Sydney Opera House as one of the most widely recognized monument all across the world.Finally the lecturer states that the entire design of the opera house cannot be confined to a single category it is an amalgation of multiple different ones which makes the Sydney Opera House as one of a kind.
