The site was formally occupied by the National Institute of Medical Research and previously by laboratories and research buildings dating back to the 1920s. A number of chemical stores, plant rooms and waste pits have been identified from plans as well as fuel storage areas resulting in extensive contamination with hydrocarbons, VOC, SVOC, heavy metals, and other chemicals. Asbestos containing materials was also found to be present across the site within made ground. The redevelopment of the site will provide 460 new residential units within 19 tower blocks.
The key elements of these works included;
Cognition agreed a remediation strategy with the regulators which provided significant savings to the client. Cognition’s methodology was to ensure minimal materials needed to be disposed off-site by bioremediating the soils which minimised residual environmental and human health risks.
The works required careful re-profiling of the site adhering to a strict materials tracking system to ensure successful delivery of the Materials Management Plan.
Cognition successfully remediated this site including all enabling works to facilitate the construction phase of the development.
