Greenwich Peninsula

Due to the dynamic nature of the environment of the Peninsula (e.g. noise and air quality) combined with incremental changes made to the original 2004 masterplan in order to adjust to the changing economic climate and market demand, RPS has been involved in a continuous process of environmental assessment for many years - advising both Knight Dragon and the former owners of the site on a succession of detailed ‘drop-in’ and reserved matters planning applications. In doing so we have worked alongside different design teams to optimise the sustainability credentials of individual development schemes and to develop mitigation measures to avoid adverse environmental effects.

As each new plot has come forward we have assessed the scheme against the outline parameters of the original outline planning permission and EIA and have updated the baseline environmental information through surveys, modelling and physical investigation.  In addition, we developed a novel approach and template for an ‘Environmental Compliance Report’ which we have prepared in support of over 10 successful planning applications from 2009 to 2017.  

The ground investigation was tailored to assess potential risks to future occupiers and the environment, including the Chalk aquifer at depth, from any existing soil and groundwater contamination beneath the site. RPS provided interpretative assessment of the soil and groundwater data obtained as part of the investigation with recommendations provided for remedial works, where necessary. Soil gas concentrations were also assessed to determine whether any protective measures would need to be engineered into the proposed development.

With structures up to 33 storeys in height proposed, we were also responsible for carrying out geotechnical assessment, with data obtained using both in situ testing (including pressuremeter testing) and ex situ laboratory methods. We provided detailed geotechnical evaluation of this data to inform the detailed design.

The investigation also included facilitating the monitoring of vibrations from the underlying Jubilee Underground Line to determine potential influence on foundations at depth.

To date, RPS has designed and managed ground investigations across the Peninsula incorporating the drilling of over 70 boreholes to depths of up to 60m below ground level, the installation of over 60 monitoring wells and the excavation of more than 40 trial pits and trial trenches.
