| The facility features a modern expressionist design, with a series of large precast concrete "shells",[14] each composed of sections of a sphere of 75.2 metres (246xc2xa0ft 8.6xc2xa0in) radius,[15] forming the roofs of the structure, set on a monumental podium. | WIKI |
| It is supported on 588 concrete piers sunk as much as 25xc2xa0m (82xc2xa0ft) below sea level. | WIKI |
| The roof is made of 2,194 pre-cast concrete sections, which weigh up to 15 tonnes each. | WIKI |
| Although the roof structures are commonly referred to as "shells" (as in this article), they are precast concrete panels supported by precast concrete ribs, not shells in a strictly structural sense. | WIKI |
| Significant interior surface treatments also include off-form concrete, Australian white birch plywood supplied from Wauchope in northern New South Wales, and brush box glulam. | WIKI |
| The shells of the competition entry were originally of undefined geometry,[34] but, early in the design process, the "shells" were perceived as a series of parabolas supported by precast concrete ribs. | WIKI |
| The formwork for using in-situ concrete would have been prohibitively expensive, and, because there was no repetition in any of the roof forms, the construction of precast concrete for each individual section would possibly have been even more expensive. | WIKI |
