Procurement and use of sustainable concrete on the Olympic Park
This case study provides an overview of sustainable concrete on the Olympic Park, including:
– the process of procuring sustainable concrete and engaging the supply chain to use it;
– the barriers faced when driving the delivery of sustainable concrete and the strategies to overcome them;
– key outcomes and achievements; and
– recommendations for future projects.
It covers both the use of ready-mix concrete and precast concrete.
The ODA worked with the concrete supplier and engaged with the supply chain to develop sustainable concrete mixes. This resulted in the use of approximately 170,000 tonnes (almost 22 per cent) of recycled and secondary aggregate, a saving of approximately 30,000 tonnes (24 per cent) of embodied carbon and elimination of over 70,000 road vehicle movements.
Rationalisation and efficiency of design reduced concrete demand by 65,000 cubic metres, saving a further 120,000 tonnes of aggregate and 20,000 tonnes of embodied carbon.
