Cognitions Bow Common Gasworks Project
From October 2022 to June 2023, Cognition Land and Water were commissioned by St William Homes to undertake contamination remediation, ground obstruction removal, materials management, earthworks, pile mat construction and associated groundworks to support the proposed redevelopment of the former Bow Common Gasworks at 120 Bow Common Lane, London.
A mixed-use, residential-led development is proposed at the site comprising five development phases resulting in 1,450 new homes, leisure facilities, associated infrastructure and landscaped public open spaces.
The remediation, earthworks and infrastructure works were completed to time and budget. Over 60,000m3 of material was remediated, processed and reused on site with over 98% reusage rate. The site was regularly audited by regulators and client representatives who were impressed by the dedication and professionalism of the Cognition team in all areas of technical, quality and safety compliance. An Environment Agency inspector made the following comment about Cognition’s management of this project:
“The Bow Common site is one of the best I have visited, being managed very well. We were really pleased to hear about all of the proactive engagement that has been carried out with local residents. If all future sites at this stage are presented and managed the same, we will be very pleased.”
