Student Village University of Exeter

A new student village at East Park for the University of Exeter comprising 11 tower blocks of student accommodation and commercial premises.

To accommodate the sloping site, many extensive new cuts are needed, and Red Rock were appointed as geotechnical advisors to Airey & Coles, structural engineers for the scheme, to assist them in the assessment and design of foundations and slope stabilisation works for this scheme.

The site is located in an area of known land slippage and many surface water issues are found surround the site suggesting shallow groundwater levels. The geotechnical performance of the Devonian Crackington can be highly variable and groundwater conditions are expected to be complex. 

Red Rock undertook a detailed review of existing ground investigation information and directed supplementary investigations specifically directed for the design of the cut slopes. Groundwater standpipes were installed to monitoring water levels in discrete zones and high quality rock cores were recovered for analysis. 

Red Rock undertook an outline slope stabilisation assessment of the two 150m long lateral 6m high slopes that cut across the site, and global stability assessments. Drawings and specification of the soil nail slope systems were provided. Foundation requirements and solutions were provided on a plot by plot basis. 

Site construction works commenced in January 2019.
