Olympic Delivery Authority chairman John Armitt on meeting sustainability targets
What we tasked ourselves and our contractors to achieve in this area is no mean feat and is unprecedented for a project of this size and scale.
Our targets include reusing and recycling 90% of demolition and construction waste, delivering 50% of materials by weight to site by sustainable transport methods and creating a new meaner, leaner and greener energy network for the area including biomass boilers, a combined cooling and heating plant and a new 120m high wind turbine.
We are aiming to build venues using materials with at least 20% recycled content and are designing them to use 40% less water. We have used natural remediation methods to clean soil, barges to take away segregated waste through newly-dredged waterways and only sustainable timber sourced through a supplier panel.
Not to mention planning the largest planting project in the UK with over 4,000 trees, 74,000 plants, 60,000 bulbs and 300,000 wetlands plants, creating a new open green space for London.
We are currently on track or exceeding our targets. For example, we are currently delivering 65% of all materials by rail or water against a target of 50%, dramatically cutting down on the number of lorries needed and the resulting carbon emissions.
Around 98% of the thousands of tonnes of waste material resulting from the demolition of over 200 buildings on site has been recycled, against a target of 90%.
These achievements have taken a huge amount of work and planning and could not have been achieved without the support of contractors and suppliers. We wanted to lift the bar for the industry and set new standards and they have more than risen to the challenge.
We have proved that if sustainability is integrated into design and construction from the very start, you can make a real difference to the way large-scale projects are delivered and the way they impact on the environment.
