Poplar Riverside London

Environmental services for the development of 2,800 new homes at the former Levan Road Gasworks, Poplar.


Client: St William Homes LLP

Services: Advisory & Planning


The former Leven Road Gasworks is being developed for 2,800 new homes by St William under the Berkeley Group and National Grid JV. Sweco were commissioned to supply environmental consultancy and ground investigation services from feasibility through to grant of consent.


We provided a variety of surveys that included three phases of ground investigation, soil stabilisation trials, DQRA, geophysical survey of gasholder bases and surveys for asbestos, air quality, odour, noise, vibration, and groundwater. 

Our work culminated in the production of a Remediation Strategy and Verification Plan for dealing with significant contamination risks, including gross contamination by coal tar and DNAPL in the superficial aquifer.

We also supported the planning consultant in the preparation of the Environmental Statement and interfaced with remediation contractors under PCSA.

The Environment Agency commended us on the quality of our engagement and submissions during the pre-application process and by the client for securing Letters of Agreement prior to consent.
