In Hochspeyer, the ground-penetrating radar investigation documents unresolved measurement anomalies and explicitly states that no clearance certification was issued. View the Hochspeyer measurement example.
For a sheet-piling section in Zweibrücken, borehole profiles, checking of a measurement anomaly and the limits of partial clearance are documented. View the Zweibrücken sheet-piling example.
The Landstuhl survey example shows how magnetic borehole profiles are assessed alongside the documented investigation scope and the limitations of a partial clearance. View the Landstuhl borehole survey example.

In the federal state of Rhineland-Palatinate, ADD's explosive ordnance clearance service supports the competent authorities in specific hazards. Local regulatory authorities are generally responsible; in urgent danger, the police are responsible. According to ADD guidance, precautionary research and checks without a specific hazard background are handled by suitable private specialist companies. Tasks, prerequisites and results required for your construction project are classified accordingly.
Identify the municipality, project address and land parcels of the actual construction area. Whether an independent municipality, collective municipality or city administration is the local contact depends on the project location and responsible administration. Planning spatially defines excavations, routes, drilling points and work areas. For several separate locations, the associated reports and official responses remain individually retrievable. A general description such as Rhine-Main area or Moselle region provides orientation; the specific procedure is clarified using the municipality affected. Further project locations are shown in the regional overview.
The existing overviews for SGD Nord, SGD Süd, Trier–West Palatinate area provide the corresponding local information. Select your project’s area; the specific municipality and affected properties remain decisive for the enquiry.
The Koblenz City Archive documents air raids in 1944 on the freight yards in Lützel and Moselweiß and residential areas that were hit. For present construction tasks, suitable historical photographs and other records are related to the actual area. Earlier development, reconstruction and subsequent ground changes receive their respective date reference. Historical indications are compared with present land parcels, construction areas and intervention depths. Assessment of an adjoining area remains linked to its own sources.
In Rhineland-Palatinate, the explosive ordnance clearance service of the Aufsichts- und Dienstleistungsdirektion supports competent authorities in preventing specific explosive ordnance hazards. Local regulatory authorities are generally responsible; in urgent danger, the police act.
For property-specific historical research and precautionary checks, ADD refers to suitable private specialist companies. The commissioned specialist company analyses available documents for the construction area described. The state service supports the competent authorities in preventing specific hazards. Before commissioning, the specialist task required, necessary authorisations and proposed result documents are determined.
For clients, this means a planned construction measure and an actual explosive ordnance find require different channels. FONTANA-EOD can prepare and perform the precautionary specialist service commissioned. In specific finds or hazards, competent bodies are involved; the project enquiry prepares the specialist service. A find is reported to the competent regulatory authority or police.
For the commissioned work, the applicable technical requirements, permits, competence and responsibilities are clarified. The actual scope of work is what matters. Tasks and interfaces are described for the project and checked against the required authorisations.
The risk assessment, work areas and communication arrangements must suit the planned activities. Specialist explosive ordnance work is coordinated with the other construction activities. Site organisation, traffic safety and other technical assessments retain their own responsible parties. Joint coordination assigns the relevant specialist work and responsibilities to the affected construction sections.
A measurement anomaly first requires specialist assessment; its appearance alone does not identify it as explosive ordnance. If an object is genuinely suspected to be ordnance, the prescribed reporting procedures and the measures set by the responsible authorities apply. Investigation reports specify the work completed and its limitations, so that results are not extended to unexamined areas or later design changes.
The ADD Rhineland-Palatinate explains the tasks of the state explosive ordnance clearance service and the local procedure. The information sheet of June 2025 distinguishes precautionary private checks from official measures in specific hazards.
The principles of clearance planning connect the investigation with its subsequent treatment. The geophysics guidance in the BFR KMR supports technical method selection. The documentation requirements relate results to the areas actually addressed. The BFR KMR describe specialist work on federal properties. For other projects, local requirements are determined separately.
The permit, qualifications and responsibilities for the specific activity are assessed under the Explosives Act and the First Ordinance to the Explosives Act. The risk assessment under Section 5 of the Occupational Safety and Health Act relates to the planned activities. The DGUV Information 201-027 addresses preventive investigation and clearance of conventional explosive ordnance and defines its scope. The references it explains to DGUV Regel 113-003 concern specific activities involving explosives; they are not applied indiscriminately to every construction investigation.
The client describes the project and provides the available project records. The operator adds requirements for use, access and timing. A coordinating contact brings the parties together; individual tasks remain assigned to the named parties. Before commissioning, it is clearly recorded what information is missing, who will obtain it and what decision the result is intended to prepare.
The specialist designers describe areas, depths, construction methods and changes. Site management coordinates the planned sequence with the construction contractors and agreed specialist works. Results are assigned to the respective intervention. A technical plan change is communicated early enough for its effect on the survey task to be assessed before construction. Organisational construction stage boundaries remain distinguishable from technical survey boundaries.
The private explosive ordnance specialist carries out the agreed investigation and documentation work. Requirements and decisions of public authorities are addressed with the responsible bodies. The documents needed for a particular procedure depend on the location and project. The technical report describes the work carried out, including its documented area, depth and scope. Decisions reserved for public authorities are made by those authorities.
ADD names the administrations of independent municipalities, collective municipalities and independent and large district towns as local regulatory authorities. In urgent danger, the police are responsible. The state explosive ordnance clearance service supports authorities through administrative assistance in specific hazards. Precautionary private research and checks are commissioned with their own service scope. Those responsible for the project coordinate the response required and document handover before the relevant work step. A need for ordnance recovery is coordinated with the permissible task and the competent authorities.
Existing knowledge is compared with planned interventions and local investigation conditions. The findings required follow from this. Method selection follows this specialist task. A city, landscape or usage designation alone determines neither the method nor a particular investigation scope for every property.
Assess historical documentsA private commission describes research, investigation or further agreed measures with the respective area and result. Necessary permits and qualifications remain relevant. In specific hazards, competent bodies carry out the hazard-prevention measures required. Unclear prerequisites are clarified before agreement and execution.
Compare investigation methodsAn excavation in a city centre raises different questions from a utility route or formerly military land. Whether explosive ordnance indications exist and further measures are required must be clarified for each property.
A city-centre excavation requires a different investigation area from a utility trench or new development area. Near the Rhine-Main area, new projects meet existing transport and utility networks. Previous uses and investigations already available must be compared with the current intervention.
For bridges, river crossings and bank structures, land-based construction areas, foundations and possible work in the water must be clearly distinguished. Narrow valleys and existing transport corridors affect access and construction sections. Proximity to water alone does not determine the suitable survey method.
Previous uses may overlap on industrial and commercial properties. Fill and remaining foundations must be considered in investigation. For such projects in Ludwigshafen and the Rhine-Palatinate area, historical documents are as important as measurement conditions and ongoing operations.
For former barracks, depots or other military land, the usage history must be described particularly carefully. Existing knowledge gaps are clarified by specialists even after dismantling or a change of ownership. The proposed construction objective determines which areas and intervention depths must be addressed.
Different documents may exist for existing urban areas, transport connections and new construction sections. For a traceable assessment, earlier results, current site plans and the specific construction task are brought together. Limitations and additional investigation needs remain explicitly identified.
Outside major cities too, previous military uses, transport corridors and local wartime impacts must be considered where indications exist. For longer routes or energy projects, changing uses and terrain conditions must be recorded section by section. Even outside a city, assessment follows the specific information about the area and planned intervention.

A utility, excavation and foundation may affect different ground volumes on the same property. Describe the individual works and their proposed dimensions. Existing findings are compared with these. Regional classification provides orientation; the actual construction area and findings required matter for the specific specialist commission.
Specialist services and investigation tasks
Previous uses and available analyses are spatially assigned to current planning. Overbuilding or changes may make comparison more difficult and are identified traceably. An old report retains its own scope. Further investigation builds on this knowledge without extending it to new interventions merely because the address is the same.
Understanding historical aerial photograph assessments
Access, known installations and planned construction phases are coordinated before execution. Preparatory work required receives a clear area of responsibility. If it affects the ground itself, it is also assessed by specialists. Scheduling considers outstanding prerequisites and results required before further work relies on their findings.
Coordinate the sequence and tasksFirst, existing knowledge and outstanding questions are clarified. This determines which research or investigation your project needs.
Aerial photographs, previous uses and available records may provide indications of wartime impacts or military activities. These indications must be assigned to the present construction area. Preliminary investigation records what is known and which information is still missing. Planning of technical measures builds on this.
Research the basis for suspected ordnanceFor accessible development areas, route sections and conversion sites, suitable geophysical methods are selected. Ground conditions, fill and existing metal affect measurability. Interpretation must distinguish measurement anomalies, method limits and further investigation needs.
Investigate areas technicallyFor deep foundations, sheet piling and larger excavations, plans showing positions, dimensions and depths and information about the construction method are required. An existing surface investigation answers this task only to the extent that its findings actually cover the ground volume required.
Information about deep-ground surveysFor suspected ordnance areas to be addressed, the clearance objective and scope are specifically defined. Approach, access, protective measures and documentation follow the commission and local conditions. The final report describes areas and depths actually addressed. Its findings relate only to those areas.
Prepare clearance measuresIn developed areas or where prior measurement is limited, suitable supervision during construction may be required. Its involvement is coordinated with site management and contractors. Before work begins, work sections, responsibilities and the response to anomalies must be established.
Provide specialist supervision of earthworksIf explosive ordnance is identified, competent bodies must be involved. Private services follow the permit, qualifications, commission and coordination with authorities. The state remit remains decisive for identification, any render-safe action required, transport and destruction as part of specific hazard prevention.
Findings and further stepsReports and maps describe which area was investigated for which task. The limits of results remain part of handover. A summary communication must not extend the scope. For later construction phases, a traceable check establishes whether their location and depth are already covered or further specialist clarification is needed.
The project file connects existing sources with investigations newly performed. Third-party reports remain identifiable with their date, area addressed and associated appendices. Measurement data and specialist interpretation are assigned to the area actually investigated. A clearance record describes the clearance measure performed and its scope. At handover, site management receives the report and area plans together. For unresolved or inaccessible areas, identify their location and specialist work required before the next intervention.
Documentation of the commissioned investigation identifies its specific purpose. In an actual hazard, competent authorities are involved. Both channels are distinguished in project organisation. The private report documents the specialist service performed. Reports of finds and official decisions required follow the respective competent procedure.
Construction companies and operators receive information on prerequisites for the next work section. The area plan and documented investigation limits remain decisive for execution; they are handed over with schedule coordination. If access, construction method or depth required changes, the affected task is compared with existing results. Responsibility for supplementary documents and further coordination is identified. Even when project participants change, specialist evidence remains linked to its actual processing status.
Historical aerial photograph analysis and other old records help locate a basis for suspected ordnance spatially. Photographs, their interpretability and area boundaries are connected with the actual construction task. The absence of a visible finding is not a technical investigation of the present ground. Other existing knowledge is included. The objective, area and result documents required are agreed for precautionary private research. Previous uses and subsequent changes retain their documented date reference. This specialist task is distinguished from official action in specific hazards.
Understand aerial photograph assessmentMagnetometry methods record magnetic anomalies. Suitability is assessed according to expected objects, ground conditions, interference and the investigation volume required. Utilities, fences and existing structures may affect interpretation. Signal strength alone does not identify explosive ordnance. Measurement, assessment and further clarification are connected with the specific specialist task. The precautionary investigation receives an agreed spatial scope and appropriate result documents. A finding is classified according to what it actually establishes, without deriving a complete hazard-prevention or disposal commission from the equipment name.
Understand the scope of magnetometryElectromagnetic investigations may be suitable for particular metallic target objects and site conditions. Selection considers the findings required, accessible measurement areas and interfering installations, not merely equipment availability. Results are documented with location and actual investigation conditions. Any supplementation required follows from specialist assessment. The permissible private specialist service is described according to the specific construction area and knowledge required. General state or region names confirm neither a uniform method nor identical ground conditions for all locations.
Understand electromagnetic surveyingUnder suitable conditions, ground-penetrating radar can provide information about subsurface structures and reflections. Ground, moisture and installations affect interpretation. A reflection is not automatically explosive ordnance; an unremarkable area does not confirm arbitrary depth. Specialist interpretation and limits are documented with the commission. An existing radar report is read according to its purpose and coverage. For precautionary explosive ordnance investigation, it is clarified which of its findings suit the construction task and which further specialist question remains outstanding.
GPR and limitationsFor deeper interventions, it may be necessary to assess whether a surface investigation achieves the findings required or another approach is needed. Positions, depths, reference elevations, drilling-point layout and known utilities are prepared for this purpose. Creating suitable investigation access is also planned by specialists. A standard grid or general depth figure does not replace this task. Precautionary investigation is related to the foundation, route or excavation actually planned. Additional groundworks receive their own comparison with existing knowledge and agreed prerequisites.
Prepare deep interventionsIf a necessary advance investigation cannot be completed, the suitability of a specialist-planned approach during construction is assessed. Investigation, interpretation and communication of findings are connected with the groundworks actually proposed. Merely observing excavation does not replace a necessary survey. Site management receives the allocation of specialist work and outstanding areas to the workflow. The permissible agreed scope and official tasks in specific hazards remain distinguishable. Supervision is not recorded as blanket completion of every question concerning the entire construction area.
Agree the approach during constructionHistorical records are connected with the present location and planned groundworks. Specialist analysis describes available indications and their limits. General local history is insufficient for this. Further needs follow from the specific question, existing knowledge and proposed intervention.
For an explosive ordnance investigation before construction projects in Rhineland-Palatinate, historical sources and the present ground are considered together. Documented fill, excavation, dismantling work and changed ground surfaces receive a spatial and time reference. The condition proposed for investigation is identified. A plan before excavation and the later excavation base may have different elevation and depth references. Existing utilities, foundations and other installations are recorded with their location. Method selection is coordinated with the knowledge sought and actual investigation conditions.
Anyone seeking investigation of suspected ordnance land in Rhineland-Palatinate also describes preparatory ground openings and site facilities involving ground interventions. For a specialist task requested as borehole clearance certification, point location, depth and scope of findings required are determined before commissioning. Conditions for a utility section may differ from those for the following deep foundation. Results and measurement limits are therefore assigned to the area addressed. A later relocation or deepening receives a renewed comparison before the relevant work begins.
Accessibility, ground conditions and existing installations affect possible methods. The findings required are therefore described before method selection. Limitations belong in planning and results. A partly interpretable area receives a traceable assessment for further work without deriving a statement of freedom from explosive ordnance from missing measurements.
After work, the questions answered and scope remaining are assessed. Additional measures receive a clear spatial and specialist reference. In specific hazards, competent bodies are involved. A private commission or general construction schedule does not replace this procedural coordination.
Provide the site plan, existing knowledge and planned interventions. Identify missing information and alternative construction approaches. The next specialist task can then be determined using the actual project. At first contact, identify the next project decision and first proposed ground intervention. Existing explosive ordnance reports are checked with their complete maps and appendices.
Agree the commissioned specialist service with its prerequisites and results. Official tasks in specific hazards remain separate. Coordination still necessary is considered before the work affected. Where needed, outstanding historical sources are researched using suitable records and aerial photographs and analysed by specialists. The method is selected according to target objects, ground, intervention depth, interference and accessibility. Investigation scope and prerequisites for execution follow from this.
Compare plan version, access and known installations with the investigation proposed. Changes are communicated in good time. Preparatory work required receives its own specialist assessment if it affects the ground itself. Once prerequisites are clarified, the agreed survey or suitable supervision is performed. Data and observations obtained are evaluated and assessed for their significance to the construction task described.
Site management receives the results report, area plans and documented investigation limits together. The next construction phase is compared with these. New or deeper interventions receive their own assessment where the existing scope of findings is insufficient. The follow-up decision identifies additions or coordination required before the next work step.
Send the site plan, planned groundworks and existing results. Identify information still outstanding. Specialist coordination determines the further work needed from these. The investigation is thus adapted to the actual task rather than deriving its scope solely from a general regional description or blanket service name.
After investigation, complete reports and maps are compared with the execution proposed. New areas or depths are considered separately. Outstanding questions remain visible to site management. Completion of a section does not justify blanket findings for all later interventions on the entire property.
Describe the planned groundworks in your enquiry and attach existing reports and plans. We check with you what information is still missing for the investigation.
Provide historical investigations, previous surveys and existing official documents. What matters is whether information is complete and the area or depth to which it relates. The new report must retain identification of information originating from older documents and results newly obtained.
Provide the site plan, intervention limits, depths and construction methods, and known utilities and obstacles. Add accessibility, construction phases and timeframe. This information helps adapt the investigation to the size of the area and proposed construction sequence.
Agree early which plans, reports and data are required. Documentation should identify what was actually addressed and which limitations exist. A subsequent change in construction scope may require renewed specialist assessment.
Agree evidence requirementsThe report describes the task actually addressed with investigated areas, depths and limits of findings. Existing sources and newly obtained results remain distinguishable. For several construction phases, each further task is compared with this scope. A shared property address does not extend the documented area.
Precautionary private services and official measures in specific hazards are recorded separately. The agreed commission defines the specialist task and results required. Authorities carry out their measures through the respective competent procedure.
FONTANA-EOD handles the agreed precautionary specialist task for the designated construction area in Rhineland-Palatinate. Before execution, available knowledge, accessible areas and results required are agreed. The private service actually proposed receives a traceable scope. Changes to planning or local conditions are assessed before the work affected. The report documents the work actually performed and its limits. Site management can distinguish the knowledge achieved from outstanding tasks and any coordination required with competent authorities.
Discuss the investigation taskMethod selection starts with the knowledge missing for the current construction task. Specialist planning considers existing results, ground conditions and actual circumstances. Available equipment or a comparable project elsewhere is insufficient as the sole basis. Selection is justified for the ground volume required. Prior private research and technical checking retain their respective purpose. Further specialist work addresses the question actually still outstanding.
Inaccessible and partly interpretable areas are identified with their actual limits. Site management can assign outstanding specialist work and additions required to them. A general total-area figure does not replace this distinction. Planning and execution agree when a suitable investigation becomes possible. For separate locations, the knowledge for each construction area remains traceable. A private partial investigation is not passed on as an official statement or complete investigation of all remaining areas.
A new location, additional depth or different construction method is compared with existing results before the work affected. Specialist planning receives the identifiable change to the research or investigation scope agreed so far. Its response and additions required are assigned to the ground volume affected. This also applies to additional work areas or a later construction phase on the same property. An unchanged address or region name does not in itself confirm unchanged knowledge requirements.
At handover, reports and associated plan appendices are provided with their area, specialist task and processing status. An overview can list research sources, actual investigations and outstanding tasks separately. It does not replace the documented investigation scope. When planners, site management or companies change, the sources for the private precautionary service and any official responses remain distinguishable. Subsequent execution receives findings appropriate to its groundworks, including specialist limits and clarification still required.
The investigation is agreed in relation to the planned intervention. Its findings follow from available sources and work actually performed. Complete results and limits belong together. A report for one area or a particular intervention is not a general certificate for every later use of the property.
Understand investigation reports and their limitationsLocation within a city or landscape region may provide indications for preparation. The specific usage history, existing knowledge and planned groundworks remain decisive. Access and ground conditions vary even within one region. The specialist task is therefore determined for your own area rather than derived from proximity to another project.
Understand the service scope
Aerial photograph interpretation is related to the actual groundworks. Its purpose and geographical scope remain distinct from a technical investigation of the ground as it is today.
Understand aerial photograph assessment
The findings, their locations and limitations are handed over together. This makes clear to those carrying out the work which area has been investigated and which task remains outstanding.
Assess investigation reports


Historical assessment, technical investigation and subsequent work answer different questions. In your enquiry, identify the planned groundworks and the information needed to prepare them.
Compare services
Preparation connects the commission, site work and handover of findings. Changes to the project can then be incorporated into technical coordination in good time.
Process and documentationFor precautionary historical research and checks without a specific hazard background, ADD refers to suitable private specialist companies. The state service supports authorities in preventing specific hazards.
Generally local regulatory authorities; in urgent danger, the police. The explosive ordnance clearance service supports competent authorities within its remit.
A current site plan, description of the proposed groundworks and existing reports with maps and limitations. Information still missing is identified. Agree requirements early before the interventions proposed. The specialist workflow connects document assessment and historical analysis required with method selection, investigation, assessment and documentation.
No. The method is selected using the specific question, existing knowledge and actual investigation conditions. Ground, interference and accessibility affect the findings achievable. Measurement limits actually remaining are documented in the results report with area plans.
Its findings apply to the documented scope. New areas, depths or construction methods are compared with it and assessed further where needed.
The affected area and limit of the findings available. Further specialist needs are determined separately for interventions planned there.
The method, area size, depth, interference and accessibility determine the work involved. Preparatory and follow-up work receive their actual service scope. Precautionary private research and checks are commissioned for a fee. According to ADD guidance, the state bears the costs of the state explosive ordnance clearance service; this concerns its hazard-prevention tasks.
Stop the affected work, keep your distance and do not touch or move the object. Inform the police on 110 from a safe distance and follow official instructions.
Attach the site plan, intervention depths and current planning version. Add the municipality, land parcels, construction method, first ground intervention and decision deadline required. Areas not yet accessible are marked on the plan. The sector overview explains typical interventions and the documents they require.
Provide complete reports and outstanding questions about the construction area. Existing sources, official correspondence and new investigation results remain distinguishable. Identify those responsible for enquiries and document handover.

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.
