The London bid to host the 2012 Games set out a plan for how the Games could play a major role in the revitalisation of east London. Equally important was to achieve this in a sustainable manner, provide value for money, and to leave a lasting legacy for east London. The Olympic Delivery Authority’s (ODA) central job was to deliver venues, facilities and infrastructure and transport in a way that ‘maximised the delivery of sustainable objectives, on time and within the available budget’. This included the supply of the innitially estimated 500.000 m3 of ready-mix concrete required to build both the sporting venues and supporting infrastructure.
