Number crunching
n The Olympic Stadium will house 80,000 seats in Games mode, but flexible design allows the venue to be scaled back to 25,000 when required;
n 33 buildings had to be demolished and more than 800,000 tonnes of soil was taken away to help create the construction platform for the Olympic Stadium – enough to fill the Royal Albert Hall nine times over;
n The total stadium site covers an area of 40 acres; n The project uses over 120km of electrical cable; n The stadium will have a total floor area of 108,500m2
during the Games;
n At 53m above ground level, the Olympic Stadium is taller than Nelson’s Column (50m);
n The stadium will contain around 10,000 tonnes of steel – it will be the lightest Olympic Stadium constructed to date;
n More than 4,500 reinforced concrete columns were installed to act as the foundations;
n The stadium is surrounded by water on three sides, so five new bridges and their abutments are now in place, connecting the stadium island to the rest of the park; and
n There will be around 700 rooms and spaces within the Olympic Stadium, including changing rooms and toilets.
Sustainability is at the heart of the 2012 project and the Energy Centre will ensure a lasting legacy of green power in the Olympic Park for generations to come

supports contractors, including T Clarke, building the venues on the park and reduces the need for temporary generators.
Smart thinking
Each company working on the site has had to demonstrate a green approach to their work. T Clarke is no exception, and as an ISO14001 accredited company it always attempts to minimise its impact on the environment. Its onsite operatives all use public transport to get to and from the Olympic Stadium site and, wherever possible, the company uses its own employees, who live locally. At the start of the project, T Clarke was allocated
space on site to house 12 20ft containers in which to store products and materials. This meant that rather than having the 50-60 deliveries that would normally be required for a job of this size, this was reduced to three. Having stock on site has also enhanced the flexibility of T Clarke’s working practices as, for instance, if work cannot be carried out on one part of the installation, operatives can start work on another without having to wait for deliveries.
Waste watching
T Clarke also encouraged manufacturers to reduce the amount of packaging used to deliver items such as luminaires and made sure the packaging that was used was recycled. Bryan says: ‘We strongly believe in recycling at T Clarke and have limited waste wherever possible. We
