The cost of the project so far, even in October 1966, was still only $22.9 million, less than a quarter of the final $102 million cost. However, the projected costs for the design were at this stage much more significant.
Ove Arup
Arup was the design engineer for the Sydney Opera House in Sydney, Australia from the project's start in 1957 to its completion in 1973. An iconic building making groundbreaking use of precast concrete, structural glue and computer analysis, this made Arup's reputation, and that of his firm, despite the extremely difficult working relationship with the architect, Jørn Utzon.
