Dealing with a very large mixed residential and commercial use building development in the UK, Cognition had to ensure their remediation strategy was both cost-effective and sustainable. Cognition’s site Investigations identified contaminants of asbestos, hydrocarbons, free product contaminated perched ground waters, and made grounds with high levels of heavy metals on the 25,000m2 site.
Cognition agreed a remediation strategy with the appointed environmental consultant for the site which would provide significant savings to the client. Cognition effectively minimised pile mat installation costs, ensured that minimal materials needed to be disposed off-site, and provided protection to sensitive neighbouring receptors, particularly the River Thames, River Lea, and Trinity Boy Wharf complex. Value engineering ensured that the most cost-effective remediation solutions were used to minimise residual environmental and human health risks. The key elements of these works included;
Cognition successfully completed site investigations, agreed a cost affective remediation strategy that provided significant reduction in disposal costs for the basement dig (>£4M) when compared with conventional strategies such as dig-and-dump and construction of traditional crushed concrete piling mats on a geotechnically challenging site.
