The preliminary survey determines the strategy followed by T&A in a soil investigation. Historical research, derived from NVN 5725, is done to determine what kind of pollution might have occurred in and in the surrounding of the research location. After this, an explorative soil investigation according to NEN 5740 takes place and, if necessary, a further soil investigation.
Based on the research results, the most suitable remediation strategy from the research is drawn up into a remediation plan. T&A performs the project management and environmental supervision for the execution of the remediation plan, so that the actual remediation can take place. After the completion of the remediation, the results will be documented in an evaluation report.
