The cost of the Populous-designed Olympic Stadium in east London is set to rise to more than £600m due to complications in the roof
The London Legacy Development Corporation (LLDC) have reached a deal with Balfour Beatty to increase the size of the £154m contract by £35.9m to cover the extra work in strengthening the stadium.
It was revealed earlier this week that the price tag for converting the stadium into a multi-purpose venue, which will be shared by West Ham FC and Athletics UK, was expected to soar by an additional £50million after complexities emerged in installing the new stadium roof.
In the latest statement the LLDC said: ‘Providing adequate support for the new roof has required significantly more strengthening work to the main roof truss, which was originally designed to be taken down after the Games. We have therefore today agreed to increase the value of the Balfour Beatty contract by £35.9m to £189.9m.
‘We will meet these costs from the project contingencies and additional income we will generate from our other developments. There will therefore be no additional call on the taxpayer and no impact on our current programme.’
The main issues at the Olympic Stadium are related to strengthening work on the structure of the stadium to accommodate the extra weight as well as complexity in design. Earlier this year cracking was spotted in some of the welds on the roof during a lifting operation at the venue.
Together the additional costs push the overall cost of the stadium to £600million. Balfour Beatty, who issued its a profit warning in September, are believed to be shouldering a proportion of the extra costs on top of the additional funds provided by LLDC - which could be up to £15m.
Once complete, the reconfigurated roof will be the largest cantilevered roof in the world and 84m wide at it’s furthest point.
West Ham are expected to move into the new home in 2016, though work on the stadium will pause during next summer when it will host five matches for the Rugby World Cup.
The extra costs are not expected to delay the construction schedule.
