St Andrews, Bromley-by-Bow, London

St Andrews is a landmark regeneration scheme delivered by Barratt London, working in partnership with the London Development Agency, the Homes and Communities Agency and Circle Anglia.

The site is located in Bromley-by-Bow, close to the 2012 Olympic Park, in the London Borough of Tower Hamlets. The St Andrews regeneration transforms a derelict site and creates new homes, community amenities and improved connections to the transport network.

Formerly a Victorian hospital, the three hectare site was essentially a walled derelict eyesore. It divided the communities and blocked access to the station. The crumbling Victorian buildings were a visual reminder of the poverty and neglect in the area. The St Andrews regeneration returns one third of the site to high quality public realm, creating new parks and play facilities. Routes through to the station improve connectivity and the new health centre and community buildings provide much needed facilities.

RSA Geotechnics involvement in the project included a reconnaissance survey and environmental desk study report; intrusive geotechnical and geo-environmental site investigation; insitu and laboratory testing; groundwater and ground gas monitoring and remediation strategy and validation services.

The programme of geotechnical laboratory testing was designed to obtain soil classification, chemical, one-dimensional consolidation and undrained shear strength parameters. The environmental chemical testing was scheduled in order to determine the levels of common contaminants and to analyse selected samples to classify the soils for off-site disposal to landfill.

RSA Geotechnics prepared a detailed interpretative report providing advice on the geotechnical and the environmental aspects of the project, including conceptual modelling and a qualitative risk assessment.  Services also included the testing and assessment of site-won materials proposed for re-use on site, to minimise the export and import of materials, reducing transport impacts and improving sustainability.
