Removal of contaminated soil combined with archaeological prospecting
Customer: Private Client
Phases: Project planning and implementation
Building costs: approx. CHF 10,000,000
In order to construct two apartment blocks on a former garden centre site, the slightly contaminated soil had to be removed to a depth of approximately half a metre and disposed of. As the project falls into an extensive archaeological zone, prospective probing and trench excavations were carried out. The excavation and disposal of the soil was furthermore subject to restrictive requirements and the specifications of the cantonal archaeological authorities. The Ecosens AG site management coordinated all the concerns, from surveys to disposal.
- Sampling of topsoil and subsoil and testing for potential soil contamination
- Evaluation of findings and results, documentation in an investigative report, including a disposal concept.
- Coordination of soil removal process with the contractor, disposal company and cantonal archaeological authorities
- Site management for the soil displacement process and disposal of the contaminated topsoil and subsoil
- Implementation and success monitoring, compilation of a final report and issuing of the required soil displacement forms
- Soil contamination up to a depth of approximately 0.5 m
- Phased soil removal by the existing construction team due to various partial advance releases
- Coordination of a sensible procedure for soil removal acceptable to all parties involved, while adhering to the superordinate specifications of the cantonal archaeological authorities
