TfL Sustainability Approach and Resource management

1. TfL Sustainability Approach and Resource management BASE London June 2013 Helen Woolston, TfL Sustainability Coordinator

2. Transport Strategy and Sustainability Goals • ‘’every day we willdeliver safe, reliable, clean sustainable and accessible transport’’ Goals incorporate sustainable development principles

4. Steps 1-3: Impact, magnitude & likelihood

5. Steps 3-4: Record Outcome of Discussions • Delivering outcomes: • Through Benefits Realisation Plans • Through Critical Design Features • Through Procurements

6. Sustainability Assessment

7. Resource Use and Waste Management • Consolidation centres • Materials Storage • Consider moving materials and waste by sustainable transport • Sustainable design eg recycled content, local materials, minimised design • Water saving measures

8. Consolidation Centres • A distribution facility through which material deliveries can be channelled to construction sites. • Materials can be carefully handled and stored where there are no opportunities to do so on sites. • By using a central location, contractors would be able to bring and store materials for re-use at a later stage and pick up other material/plant during the same journey, improving the overall resource efficiency of a construction project.

9. Materials Storage Contractors should consider suitable locations where to store materials and/or equipment Locate away from sensitive receptors (eg residents) to avoid disruption while accessing the stores during sensitive hours A dedicated storage area would eliminate or reduce the need to bring materials by road each shift

10. Sustainable Transport of Materials and Waste • Distribution Service Plans • Transport by rail, barge, river • Eg Crossrail excavated material to Wallasea Island, new RSPB reserve

11. Water Saving Measures • Identified by contractor for a new project: • Use of Siltbusterto process concrete washout to a suitable standard for re-using wastewater for cleaning purposes or dust suppression on site • Agreement with concrete suppliers to washout at their facilities • Rain water harvesting to allow for re-use of water for dust suppression and/or cleaning of welfare units, by allowing space for catchment area when designing welfare facilities • Use of concrete cloths as an alternative to traditional concreting in-situ for stabilising of ground. Alternative material brings a low environmental impact in terms of less water required, no wastage, no nuisance generated by having to break it down when no longer needed.
