1. We need a reliable statement on the explosive ordnance situation. Are we in the right place?

Yes, in a combined aerial photo and file evaluation, we prepare an expert opinion for you that shows whether or not there is a potential explosive ordnance load in the evaluation area.

2. How long does it take you to process an explosive ordnance investigation?

The processing time of plots (standard case) is about 14-16 weeks. The fastest possible statement is possible in about 5-7 weeks with free capacities (express variant).

3. What is the workflow of an explosive ordnance investigation?

Here we explain what the process of an explosive ordnance investigation looks like.

4. Do I get a statement about my area immediately with the "request explosive ordnance investigation"? Do I already incur costs?

No, we first create a non-binding and free offer based on your area marking under "Request".

5. How much does an explosive ordnance investigation report cost?

The price of an explosive ordnance investigation depends on various factors. The size of the area and the basic information to be obtained are the most important factors. We will gladly calculate an individual offer for you.

6. How do you come to a conclusion about a potential explosive ordnance load? Which bases are relevant here?

The focus is on a multitemporal (aerial photos over the entire war period) and stereoscopic (3D) aerial photo analysis. In parallel, information from file documents, technical literature, secondary literature, as well as contemporary witness statements or community research is determined in order to obtain a reliable statement. In forested areas, a digital terrain model (DTM) can be used, since traces of bombardment can still be detected in the present-day terrain surface. The combination of these sources of information allows a well-founded conclusion to be drawn about potential contamination.

7. What is the result of the preliminary exploration? What do I get as a customer?

As a result of the Explosive Ordnance Investigation, you will receive a report of the results. The report shows whether or not a potential explosive ordnance load has been identified after reviewing the historical aerial photographs, sources and literature. If this is not the case, there is no need for further action according to the Baufachlichen Richtlinien Kampfmittelräumung (BFR KMR). If indications of potential explosive ordnance contamination are identified, a recommendation for further action will be made.

8. What is the next course of action if a potential explosive ordnance hazard is identified during the evaluation?

If indications of a potential explosive ordnance load are identified in the course of the preliminary explosive ordnance investigation, we indicate: "In accordance with the construction guidelines for explosive ordnance clearance, there is a need for further investigation (BFR KMR)". Depending on the results of the explosive ordnance survey, a recommendation is made for stage 2 of our offer, and if necessary, consultation with the explosive ordnance disposal service or a specialist company for explosive ordnance disposal.

9. Do you also perform investigations/probing in the field

No. We work without sampling, i.e. we evaluate historical aerial photographs from the time of the Second World War as well as corresponding sources and literature. This saves time and money in the run-up to the construction project and ensures planning reliability. In the event of potential contamination, we will be happy to refer you to specialist companies who will continue to work on the basis of our expert opinion.

10. When is stage 2 of the offer necessary?

Level 1 is sufficient for determining whether or not a potential explosive ordnance hazard exists. If explosive ordnance-relevant findings are identified within the project area, we recommend level 2 for the measurement of the findings or for the exact determination of used ordnance. Relevant aerial photographs are located in the Geographic Information System (georeferenced).

This means that areas without potential explosive ordnance contamination can also be identified. All findings can be taken from a list of coordinates and a results map. These results serve as a further basis for work in explosive ordnance disposal. If it is not possible to determine the risk, it may be necessary to refer directly to a specialist company for the removal of explosive ordnance.

11. Why do additional images need to be obtained for explosive ordnance investigation?

In addition to the images available in our archive, further aerial photographs are being obtained and evaluated. In order to obtain a reliable statement on a potential explosive ordnance load, a good temporal and spatial coverage with aerial photographs must be carried out over the entire war and post-war period. In doing so, we minimize all gaps in our knowledge as far as possible.
