The first stage of the land remediation project was to review site information provided by the LCC and determine whether we needed further data and assessments. Our team recommended a pilot remediation trial and managed its implementation.
Our scope included:
• Excavating and processing 1000 tons of waste
• Determining the amount & type of recovered materials in the excavation work
• Confirming the quality of residual soils, which would guide the ground engineering
Our Geotechnical team carried out additional ground investigations and ground gas monitoring. Phase 2 included the earthworks design of the replacement engineered fill and outlined measures to control landfill gas, a crucial step in enabling safe, residential housing development. In addition, we conducted quantitative modelling of predicted settlement’s and made surcharge recommendations to mitigate future settlement. As a condition of the pre-planning phase, we provided groundwater and ground gas risk assessments to secure regulatory approval from the environment agency to treat any excavated wastes.
