ABSTRACT
Chapter 14 considers the procurement, design and construction of the Sydney Opera House from a construction law perspective. The procurement was the result of the winning entry in a world-wide architectural competition. The original concept design of a thin concrete shell was not feasible, and after years of design work using thousands of hours of computer time the final design incorporated a complex space frame of massive prestressed concrete ribs. The originally constructed podium required substantial additional piling for the increased weights. The contract for construction of the concrete superstructure was a “cost plus” contract. Design and construction involved many cutting-edge innovations. Due to differences of opinion between the architect and the government, the architect resigned before the final stage of design was completed. The interior and glass walls were designed by a different architect. The government ultimately commissioned the original architect to formulate the “Utzon Design Principles”, which were the basis for a substantial refurbishment, and will be the basis of future conservation of this World Heritage listed building.
