Case Study – Former Chesterfield Arms

Hartshorne, Derbyshire


The Chesterfield Arms public house was demolished in 2010 in order to make way for the development of 14 residential properties.

We were employed by the developer, Sharpe Properties, to undertake a Phase I and Phase II site investigation with an objective of discharging the planning conditions imposed on the site and to propose recommendations for foundation and floor slab construction.

In addition we carried out percolation tests on the ground in accordance with BRE 365 to establish the suitability of the ground for soakaways.

We were also instructed to undertake detailed foundation design taking account of the shrinkage potential of the ground and the influence of nearby trees.
