World Cup 2010: Junglegenius

Designers of the Mbombela Stadium, which stages its first World Cup match next week, took their inspiration from African animals in the nearby game reserve.The Honduras versus Chile match on 16 June may not be a glamour tie but it will be the first competitive match at the iconic Mbombela Stadium in Nelspruit.
Mbombela Stadium is the most intimate andcompact of all the World Cup venues with 43,500 seats arranged in a three-tiered bowl. At £66M it is also the most cost effective of all the 2010 stadiums in terms of per-seat cost.
Working withSouth African architect R&L and lead engineer Goba, Mott MacDonald was responsible for the stadium’s super-efficient roof and for the dynamic analysis of the stadium bowl. The lightweight roof structureis composed of steel trusses with primary trusses cantilevering 40m from concrete piers surrounding the stadium.
When the project kicked off, world steel prices were soaring and the structuralengineers set out to control costs by minimising the quantity of steel used in the roof’s construction.
“We went through a number of design iterations with R&L, each time refining the design to increaseefficiency,” says Mott MacDonald project manager Paul Officer.
The result is a roof weighing less than half as much as the average trussed stadium roof - just 55kg/m2 - setting new standards for...
