The construction and management of the sports hub was placed under a private-public partnership (PPP) scheme for a 25-year lease period.11 This meant that the selected developer was required to design, build, finance and operate the Sports Hub during the lease period. The government, through the Singapore Sports Council (now Sport Singapore), would then reimburse the company with an annual sum until the end of the lease.12 In December 2005, at the preliminary stage of the tender process, the project was estimated to cost between S$650 million and S$800 million, making the sports hub the biggest PPP project in Singapore.13 However, the budget increased to S$1.87 billion when the tender was awarded on 19 January 2008. One of the reasons cited for the larger cost was the addition of a water sports centre. The Sports Hub is the biggest PPP sports facility project in the world.

原始計畫是6000~8000萬新幣,後來一路調高(1.3億是過程中的一個數字),最後因為加上water sports centre,所以才漲為1.87億新幣

整個Singapore Sports Hub,包含以下

The centrepiece of the Sports Hub is the 55,000-capacity National Stadium with a dome-shaped retractable roof. The stadium stands at 82.5 m when the 310-metre-wide dome is fully closed.42 The bowl-shaped stadium is fitted with a cooling system that pumps out cool air from beneath the seats. In addition, its seating can be configured to suit a variety of events from sports such as rugby, cricket, football and athletics, to concerts, family entertainment shows, as well as national and community events. It is the only stadium in the world capable of hosting such a wide range of events.43
