The Ridge Geo-Environmental Team has recently completed a Ground Gas Risk Assessment for a rural barn development for holiday letting in Cricklade, Wiltshire.
Contamination planning conditions were applied to the development, and following the review of a Stage 1: Risk Assessment (Desk Top Study) which was completed by others, a Site Investigation Scope was submitted to the Local Authority for approval of proposed intrusive investigatory works.
Site works included the drilling of boreholes with a dynamic sampling rig, and the installation of gas monitoring wells in the immediate vicinity of the barn.
A gas monitoring programme was completed in accordance with guidance BS 8576 (2013) Guidance on investigations for ground gas – Permanent gases and Volatile Organic Compounds (VOCs), and following the review of data, Ridge was able to assess the site’s ground gas regime.
Following the submission of the Ground Gas Risk Assessment Report to Wiltshire Council, contamination conditions were discharged and the development was finalised.
