When there are indications that a project site may contain unexploded ordnance (UXO), BODAC can conduct a (historical) research before earthmoving activities are carried out. The aim is to give a well-founded advice on the presence or absence of UXO and the necessary steps to be taken. This research is done according to Dutch WSCS-OCE certification and in conformity with the standards of the Dutch association of explosives detection companies, the Vereniging voor Explosieven Opsporing (VEO).
Historical research consists of:
- researching literature;
- researching (inter)national, regional and local archives;
- researching flight records of bombing missions;
- research into and analysis of available aerial photographs;
- analysing execution orders of the EOD;
- hearing of witnesses (if possible).
The findings of the historical research are detailed in a report with accompanying UXO soil contamination chart (GIS).
Follow-up actions that (may) arise from historical research are:
- preparing various plans (project plan, including SHE plan, estimate and time schedule);
- performing a soil analysis: environmental, archaeological and geotechnical soil research;
- performing digital and/or analogue detection activities;
- performing all necessary civil engineering work.
