Contaminated Land - Stratford City regeneration

Purpose

Stratford City was a £4 billion retail-led urban regeneration project covering 73 hectares (180 acres) of the former Stratford rail lands surrounding the Stratford International railway station for the Channel Tunnel Rail Link (CTRL). The site formed a significant part of the wider 2012 East London regeneration area. The site was heavily contaminated with oils and diesel from the former railway use, as well as contamination from a former gas works.

Our team were appointed as the contaminated land consultants for the project. We commenced work on the site in April 2007 and continued until 2012.

Outline / Scope of Works

We provided additional support in waste management exemptions, waste classification and ‘WAC' testing, determining the suitability of site materials for reuse within the development, overseeing asbestos removal, the installation and subsequent monitoring of boreholes, liaison with regulatory bodies and tender reviews.

Outcome / Client Benefits

Works undertaken by our team included the analysis of over 500 soils and 150 groundwater samples, the introduction of a unique solution to Japanese Knotweed, resulting in the reuse of 50,000m³ of material on-site, and a bespoke Waste Management Strategy which has successfully diverted 125,000m³ of hazardous waste from landfill and resulted in significant cost savings of approximately £40 million compared to original estimates.
