Lovely location for new home owners means challenges for engineers
Phase 2 of Woodberry Copse, a 54 home residential development by Bloor Homes South West in Lyme Regis Dorset, is preparing to open its doors to new residents.
Whilst the setting of the development alongside picturesque coastal scenery in the ‘Pearl of Dorset’ will be delightful to the occupiers, the challenging geology and geography of the site location has required specialist engineering skills to deliver commercially viable design solutions.
The site is in an area with a history of ground instability as a result of underlying geology which comprises limestone, siltstone, clay and mudstone overlain by Cretaceous sands.
Clarkebond was appointed to provide detailed infrastructure design on both phases of the development including detailed plot design, roads, drainage, foundations and also flood risk assessment, transport planning and superstructure design.
The variable ground conditions on the site, including artesian water pressure, have required a complex foundation solution of piling and reinforced concrete ground beams to support loads from buildings and suspended ground floor slabs above.
Clarkebond also prepared Transport Assessments and Residential Travel Plans to accompany planning applications. Concerns over traffic management were allayed by the construction of a new access road serving both phases and Clarkebond were able to demonstrate that a large number of education, employment, health, leisure and shopping facilities including the town centre, were in comfortable walking distance, with a regular bus service also in place.
