Methods

Methods and services in the references

Downhole magnetometry

Explosive ordnance deep-ground survey using 3-axis downhole magnetometry, setting out borehole positions, drilling boreholes, on-site interpretation, borehole evaluation, preparation of a georeferenced measurement report, and additional opening / supplementary drilling where indications of explosive ordnance occur.

Surface radar

Explosive ordnance ground-penetrating radar (GPR) survey of near-surface construction and intervention areas, georeferenced evaluation, documentation, clearance of suspect points and clearance statement; supplemented by ordnance specialist supervision of groundworks.

Clearance and investigation of anomalous points

Anomalous points and affected working areas are addressed within the documented scope. Clearance, recovery and final checks are distinguished according to the actual task.

Area and volume clearance

Surveying and documentation

Unambiguous spatial assignment connects project areas, measurement data and results documents. Scope and limits of interpretation remain traceable together with the plans.

Survey report and clearance record

Exploration and clearance plans

Investigation objective, working area, method selection and documentation scope are brought together before work begins. The specific task of the construction project is decisive.

Your enquiry

What information helps with selection?

Construction project and intervention

State the type of construction project and affected working area. For example, are utility trenches, foundations, a larger construction area or individual borehole positions planned? A site plan and proposed intervention depths help describe the task.

Methods and conditions

Tell us which investigation or service is requested and what documents already exist. Information about existing structures, utilities, ongoing operations or working areas available in sections helps assess comparability.

Required supporting evidence

Do you need a project description, confirmation of a particular service or evidence for a tender? Specify the required form and period of work being considered. This identifies which information is essential for your decision.

Comparability

Information for a specialist comparison

When selecting, check whether the type of work, construction setting and requested service match your project. Information about access, existing utilities and ongoing operations helps identify differences.

For a specialist comparison, the investigation objective, areas or points worked on, method used and documented limitations matter. State the planned ground volume affected and intervention depths for your project. This information allows discussion of which project information and supporting evidence fit your enquiry.

For work accompanying construction, the type of service is particularly important: visual observation of excavator spoil alone is not an explosive ordnance survey during construction under DGUV, FAQ 4. Therefore ask about the actual investigation sequence and associated supporting documentation.

Specialist news and media

Public news and documentation can be found in the separate media section. These articles explain finds and historical contexts. In your project enquiry, you can refer to the article and the question it addresses.

Project enquiry

Have your project assessed

Whether historical aerial photograph analysis, explosive ordnance surveying, surface surveying using GPR, magnetometry or TDEM, deep-ground surveys, downhole surveys, excavation supervision, area clearance or ordnance recovery is needed depends on the location, ground disturbance, depth, ground and existing documents. An early ordnance assessment provides clarity for tendering, programming, occupational safety and construction.

FONTANA-EOD combines its Section 7 SprengG licence, specialists holding Section 20 SprengG certificates of competence, suitable survey and clearance methods, and traceable documentation. Send the site plan, depth of ground disturbance, construction phase and existing documents for an initial technical assessment.
