In conjunction with Engineering Paddler Designs (EPD), Patrick Parsons was involved in the installation of Rapidbloc technology at Lee Valley – the London 2012 Olympic course.

Patrick Parsons’ involvement at the Lee Valley course continued with a prestigious Olympic Legacy contract. Following the popularity of the £35m course, we assisted in designing and procuring a further £4.6m of additional supporting facilities to the site, including an extension to the visitor centre, a new pavilion and new car parking facilities.

Patrick Parsons provided geoenvironmental services to the sensitive site in an alluvial valley, which included former landfill areas. This involved 9,000 tonnes of slightly leachable, non-hazardous clay fill to be designed for re-use within soft landscaped environmental bunds and external seating areas, capped with low permeability soils to protect users and minimise rainwater infiltration.  Re-used, pre-designated recycled demolition fill materials, which contained sporadic asbestos fibres, were also used to form car parking areas. In depth liaison was required with the local authority to agree capping and re-use of granular fill prior to works. Patrick Parsons undertook supervision and validation of all reclamation and restoration works.
