Explosive ordnance surveying and disposal in Völklingen

Collect earlier explosive ordnance reports and their associated maps. Compare old hall and operational designations with the current plan. Clear assignment is particularly important where parts of the property have been altered or newly developed. Historical use and an earlier investigation are different kinds of information. What matters for the new task is which area was actually investigated and with what result.

An old report may already cover a section now known by a different name; equally, a familiar operational name may include an area extended later. The marked boundaries, height reference and documented conclusions remain decisive. Therefore also provide the associated overview maps and appendices. If an area cannot be assigned clearly, the unresolved location question is identified. Specialist planning can thus continue using suitable existing results and relate additions to the volumes of ground that actually remain unresolved.

Describe access, working hours and known technical installations. Specialist planning clarifies how the conclusions needed can be achieved under these conditions. Areas usable only temporarily are explicitly included in the sequence. An investigation of an adjacent open area does not replace conclusions about an area that remains occupied if its ground is not covered by the documented scope.

For an access route usable only temporarily, the plan describes in advance when each working area may be available and who coordinates access. This does not yet promise that the necessary investigation can be completed within that period. Specialist planning also considers the required survey positions, existing installations and investigation scope. If the operator changes the available area, the new situation is checked before execution. Necessary preliminary works involving their own ground interventions are considered separately. They must not be brought forward unchecked as mere preparation ahead of a necessary explosive ordnance investigation.

Record in the report which sections were addressed and which limitations remain. These include restrictions due to lack of access as well as survey conditions. Site management receives the maps and explanations together. If an area that becomes available later is needed, the additional task can be described specifically without indiscriminately discarding results that already fit.

The results plan distinguishes an area not yet reached from an area surveyed but interpretable only to a limited extent. Both may need further clarification, but for different reasons. In the first case, access and timing need to be clarified; in the second, a supplementary measure justified by specialist assessment may be needed. Site management receives the respective cause with its location and the conclusions needed. A blanket statement of remaining area would obscure these differences. When further work is carried out later, the new result is related to the earlier status so that the planners and contractors can identify the current scope of the unresolved task.
