MacDonald used the BIM model in a 4D Navisworks analysis package to show how the building could be put together in the timescale. ‘These were not all from a construction planning background so if we’d put a programme chart on the wall they’d have struggled to understand it but, because they could see it being built virtually, everything was immediately clear and they bought into it,’ says Middling. The result was a compromise, with lead times reduced to six months. The detailed modelling paid off. The

venues were completed on time and were used successfully for the Olympics. For the record, the actual trusses used to support the venues started life as the staging for Madonna’s 2008 Sweet and Sticky tour. And, true to Mott’s sustainable ethos, the structure is supported on piles which are actually sections of oil pipeline reclaimed in Aberdeen. The piles have been driven into the ground and fitted with a specially developed pile cap. Once the structures have been dismantled the piles will be pulled from the ground and used elsewhere. Fittingly, the final use of the BIM model

was to visualise the process for taking the buildings down; a process now currently underway. However, if you missed the opportunity to visit the venues at the 2012 London Olympics, negotiations are underway for venues to be re-used at the 2014 Glasgow Commonwealth Games – now that would be a truly sustainable Olympic legacy.
