Further to revision of site human health risk assessments and detailed ground modelling for the proposed development a development specific remedial strategy was developed to help maximise the re-use of site won materials.
This included the encapsulation of Japanese Knotweed impacted soils within POS areas alongside bio-remediation of hydrocarbon sources.
All remedial operations were co-ordinated with engineering platform construction to enable the site for piling and road & sewers works within 12 weeks of operational start. Soils and knotweed management was provided through the groundworks package to ensure adherence to the overall site Material Management Plan.
DB provided full validation of enabling, remediation and material management gaining regulatory approval to meet constructions requirements.
