Project pathway
The quickest route to the right decision.

Are you assessing land for construction or future development? A regional plan designation does not establish which explosive ordnance documents exist for the property. FONTANA-EOD helps projects in the Münster administrative district turn an initial site idea into a specific investigation task.
Distinguish the development objective from the construction area.
Collect existing knowledge about the area.
Consider the first exploratory works too.
For projects in the Münster administrative district, regional planning statements are distinguished from findings for an individual property. We interpret existing documents for the next decisions. Exploratory works and other early ground interventions already proposed are considered with their location, construction method and the findings required.

Explosive ordnance survey – Dülmen – Coesfeld – Railway line, Dülmen–Coesfeld
Service period: 2026-09
Service areas:Downhole magnetometry / deep-ground survey

The Münster administrative district is in North Rhine-Westphalia. The Westfalen-Lippe explosive ordnance disposal service of the Arnsberg district government is responsible for state explosive ordnance tasks in the Münster administrative district. Its current guidance on wartime aerial photograph analysis identifies only local regulatory authorities as applicants. The municipal route is therefore clarified first for your project. Regional plan documents support spatial classification but do not replace property-specific analysis or investigation.
For an explosive ordnance survey in the Münster administrative district, the municipality concerned, project address and cadastral parcels are identified. Where several site options exist, each area receives its own site plans and explosive ordnance documents. The responsible local office follows from the actual project location. A shared project name connects subprojects organisationally; for specialist work, location, intervention and existing knowledge remain individually traceable. Identify the decision approaching next and any groundworks already proposed before it. These may include exploratory works, creation of access or removal of underground structures. Further project locations are shown in the regional overview.
Information on explosive ordnance surveying in Münster, Gelsenkirchen, Bottrop, Recklinghausen, Marl, Gladbeck, Dorsten, Herten, Ahlen, Ibbenbüren, Bocholt, Castrop-Rauxel and Rheine helps you prepare your project enquiry. The documents and proposed ground interventions on the particular property are decisive.
The Münster administrative district includes both Münsterland and the Emscher-Lippe region, comprising Bottrop, Gelsenkirchen and the Recklinghausen district. The Münsterland regional plan must therefore not be equated with planning for the entire administrative district. It describes spatial development within its planning area and provides a framework for subsequent planning levels.
Historical findings are assigned to a place and time. The municipal chronicle of the air raids on Rheine in 1944 documents attacks on the city, railway station and industrial facilities, for example. For present-day construction areas, suitable historical images and further records are related to the actual property. Subsequent reconstruction, demolition and ground changes receive their own temporal and spatial reference. Such local findings are assessed for the area investigated; neighbouring properties require their own respective basis.
The decision on the Zollvereinring gas pipeline in Gelsenkirchen of 3 August 2020 contains, in Section 6.4, separate requirements for exploratory boreholes and piling and drilling work alongside the application for explosive ordnance assessment. For pipe jacking, the additional survey needs described there also depend on the proposed method. When preparing a route, individual groundworks and construction methods should therefore be identifiable on the site plan and checked against the associated official conditions. An approved utility route alone does not describe which checks are needed before a specific work step. The decision's conditions apply to the project at that time. For other projects, the respective applicable requirements and proposed intervention are determined. Investigations or clearance work carried out are assessed using their own service and result records.
Explosive ordnance assessment depends on the property actually concerned and the intended groundworks. A regional planning designation is not an investigation result for that property. Therefore collect specialist documents separately even if the proposed use is already identifiable in the regional plan. Only comparison with the specific project establishes the questions still needing clarification.
For explosive ordnance assessment before construction projects in the Münster administrative district, existing investigation results are also related to current plans. A small utility section and a deep excavation pit may have different investigation objectives. A relocated access route or newly chosen foundation therefore receives its own spatial and technical comparison. Each variant records which subareas are accessible, which usable results exist and which specialist task is required before the first intervention. Property comparison thus receives a traceable document status rather than a combined overall area figure.
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 Münster district government describes the administrative district. The Münsterland regional plan sets out spatial development within its planning area. The state wartime aerial photograph analysis is requested through the local regulatory authority. The Westfalen-Lippe explosive ordnance disposal service supports municipalities within its remit.
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 in the Münster administrative district, local requirements and responsibilities 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.
For private activities in North Rhine-Westphalia, the specific requirements of the exceptions under the KampfmittelVO and the official guidance must be observed. The private contract connects technical suitability with the scope provided for in law. The authority's state of knowledge and the permissions required for the activity are checked before an agreement.
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.
The local regulatory authority coordinates the municipal procedure and involves the Westfalen-Lippe explosive ordnance disposal service of the Arnsberg district government within that service's remit. According to its guidance, only local regulatory authorities are authorised to apply for state wartime aerial photograph analysis. A private commission separately describes the permissible specialist task and authorisations required. The client and designers coordinate which official response is needed before the work step concerned and who passes documents to those carrying out the works. Any need for ordnance recovery is coordinated with the permissible task and the competent authorities.
The specialist findings required for the approaching site or construction decision are established first. Available historical knowledge and proposed interventions provide the reference. Method selection is justified from these and the site conditions. A regional plan designation or shared location within the administrative district does not determine an investigation method for an individual property.
Assess historical documentsEven an early intervention is coordinated with the competent authorities and existing knowledge. Private specialist services receive a clearly limited task under the prerequisites of the NRW procedure. Permissions required are checked beforehand. A main investigation proposed for later does not replace specialist preparation for groundworks already planned before it.
Compare investigation methods
For each area considered, existing knowledge and outstanding questions are compiled clearly. Differences in document status remain visible. An alternative with extensive documentation is not assessed as more problematic solely for that reason than an area with little investigation. Instead, comparison describes the findings actually available and the further clarification required for the decision.
Document findings and their limitations
Exploratory works or other preparatory activities may affect the ground even before construction itself. Identify the specific proposed measures with their location and available depth information. Their technical assessment receives its own reference. An outstanding later use does not replace assessment of works already proposed in the early project phase.
Specialist services and investigation tasks
Regional plans, municipal land-use planning and property-specific investigations answer different questions. They are identified accordingly in the document overview. A suitable planning designation does not, by itself, establish the explosive ordnance present in an individual area. For the next intervention, the site-specific knowledge actually available is therefore considered separately.
Coordinate the sequence and tasksThe specialist service is determined by the planned ground intervention and the conclusion required for it. Which activity may be privately commissioned under the specific North Rhine-Westphalia procedure is clarified separately before an agreement.
For the commission, the first groundworks actually proposed are defined from the initial site idea. These may include exploratory works, creation of access or removal of underground structures. Location, depth and construction method are linked to existing explosive ordnance documents. This allows it to be established whether documents need interpretation, further ground volumes need investigation or assessed findings need further work. The permissible commissioned specialist service and required results receive this scope. A regional planning statement alone describes neither the specialist task nor the knowledge available for the property.
Define the specialist taskBefore work is carried out, actual survey access, utility information and interfaces with other trades are clarified. Even for early exploratory works, preparatory activities that themselves change the ground are described. Prerequisites required depend on the method and site. Additional opening-up work or other interventions to create investigation access are prepared by specialists and are not undertaken independently. Outstanding site variants remain separate with their respective areas and documents. Subsequent construction plans are not assumed to be an already established basis for early work.
Clarify preparatory work in the programmeThe commission describes the current information needs and the groundworks planned first. Assessment and handover of results are part of the process. Effort and dates depend on actual access, documents and coordination. Even if the final use remains open, the findings needed now are defined specifically. Site comparison, technical exploration and later construction are recorded with their respective tasks. Changes in development planning are compared with the agreed specialist commission; they do not automatically extend its investigation scope.
Discuss the scope and scheduleIdentify cadastral parcels and show the area on a legible site plan. If several sites are initially being considered, keep their documents separate. A response for a neighbouring commercial site cannot simply be assigned to the new property. Later construction plans need not be complete for an initial discussion, but their present status should be identifiable.
Ask for earlier assessments, investigation reports and associated plans. A statement in a property brochure does not replace the original report. Check whether appendices are missing and whether the boundaries described can be identified on the present site plan. If something remains unclear, identify that gap for further work rather than assuming a favourable or unfavourable finding.
Geotechnical exploratory works, trial pits or works for temporary access may already involve ground intervention. Include such measures in coordination even if they precede the actual start of construction. Whether explosive ordnance measures are required beforehand, and which ones, must be clarified from existing knowledge and the proposed interventions. Calling them preliminary investigations does not pre-empt this decision.
If only part of the area is to be developed initially, show that section separately from areas not yet planned in detail. State which findings are required now. A report for the first construction section should not later be used as evidence for the whole development site without checking its actual spatial and technical reach.
The overview identifies the underlying areas, documents and next proposed works. Unresolved points are allocated explicitly. A site decision can thus be traced using the knowledge available at the time. Later investigations add to this basis without retrospectively claiming a broader scope of findings for earlier documents.
A shared overview for several sites retains differences between subareas. It records the reports available for each, their plan revision and the area actually investigated. An outstanding edge strip or inaccessible subarea is marked on the site plan. Site management can use this to derive tasks still required for the next section. At commissioning, achievable findings, result documents required and prerequisites are coordinated together. Preparation and reinstatement retain their own services and responsible parties.
Results from an initial exploration phase are handed over in full to subsequent planning with maps and limitations. Their scope remains identifiable even as the project becomes more specific. New areas, construction methods or depths are compared again. A completed early task is not used as blanket evidence for all subsequent construction work.
A result from the early project phase is related to the later overall construction project within its documented scope. New areas, construction methods and depths are checked against existing findings. The results report, area plan and appendices remain together. A clearance record is assigned to the clearance measure actually carried out and the area addressed. At handover to other design or construction companies, these underlying documents remain linked to the current intervention plan.
Assign site plans, existing results and next proposed works to each alternative. Identify missing information and different plan revisions. This makes it clear which questions must be answered for selection and which only for later construction. Coordination can focus on the respective decision and its required scope.
If a site is pursued further, the construction method, areas and depths are compared with existing knowledge. Questions already addressed remain usable insofar as their scope fits. New requirements are added specifically. The transition from a broad site idea to specific construction thus receives a traceable technical basis.
Historical aerial photograph analysis and other earlier records help establish the spatial basis of a suspected hazard. Images, interpretive capability and area boundaries are related to the site actually considered. An absence of visible findings is not a technical investigation of the present-day ground. Other existing knowledge is incorporated. Where several development options exist, each area receives its own allocation. A statement from the regional plan or another property does not replace this basis. Historical assessment is checked against groundworks already proposed before the final development plans.
Understand aerial photograph assessmentMagnetometric methods detect magnetic anomalies. Suitability is assessed in relation to expected objects, ground conditions, interference and the ground volume requiring investigation. Utilities, fences and existing structures can affect interpretation. Signal strength alone does not identify explosive ordnance. Surveying, assessment and further clarification are linked to the specific specialist task. Results for early exploration points retain their actual spatial scope and purpose. Their position within a development area does not, by itself, confirm findings for an overall construction area defined only later.
Understand the scope of magnetometryElectromagnetic investigations may be suitable for certain metallic target objects and site conditions. Selection considers the findings required, accessible survey areas and interfering installations, rather than equipment availability alone. Results are documented with their location and actual investigation conditions. Additional work required follows from specialist assessment. The investigation task is determined by the groundworks already proposed. An outstanding site development does not justify either blanket equipment selection or treating all potential areas as equivalent.
Understand electromagnetic surveyingUnder suitable conditions, ground-penetrating radar can provide information about subsurface structures and reflections. Ground conditions, moisture and installations affect interpretability. A reflection is not automatically explosive ordnance; an area without anomalies does not confirm any arbitrary depth. Specialist interpretation and limitations are documented with the commission. An existing radar report on ground conditions or installations is read according to its purpose and coverage. Early site assessment and the information needed before the next actual intervention remain separately traceable.
GPR and limitationsFor deeper interventions, it may be necessary to assess whether investigation from the surface can provide the findings required or whether another approach is needed. Positions, depths, reference elevations, borehole layouts and known utilities are prepared for this purpose. Creation of suitable investigation access is also planned by specialists. A standard grid or general depth figure does not replace this task. Exploratory boreholes and subsequent construction methods are described with their own ground volumes. A planning statement about site development does not replace the necessary definition of the technical task.
Prepare deep interventionsIf a necessary advance investigation cannot be completed in full, it is assessed whether a specialist-planned approach accompanying construction is suitable. Investigation, interpretation and communication of findings are linked to the groundworks actually proposed. Visual observation of excavated material alone does not replace a necessary survey. Site management receives the allocation of specialist work and outstanding areas to the work sequence. Preparatory works and later construction phases are recorded with their respective prerequisites. An approach in an individual approval decision is not transferred to other sites without project-specific comparison.
Agree the approach during constructionThe state wartime aerial photograph analysis for the Münster, Arnsberg and Detmold administrative districts is undertaken by the Westfalen-Lippe explosive ordnance disposal service. Local regulatory authorities submit applications to this service. Therefore clarify the local procedure with the municipality in which the property is located. General regional planning and work on a specific suspected explosive ordnance hazard serve different purposes.
For investigation of an area with suspected explosive ordnance in the Münster administrative district, elevation reference, proposed depths and known ground changes are considered together. A plan before ground removal and a plan for the later excavation base describe different states. Investigation planning therefore identifies the state to which findings are to relate. Existing utilities, foundations, reinforcement or larger metal installations are recorded with their locations. They may affect accessibility and interpretability. Method selection is adapted accordingly; survey limitations that actually remain are documented.
Early exploratory works receive the same specific description of their own intervention as later construction. For a specialist task requested as borehole clearance, point location, depth and the findings required are determined before commissioning. Trial pits, trenches and other exploratory works identify the areas actually affected. Specialist planning assesses which investigation is suitable for this work and feasible under site conditions. Before the location or construction method changes, the scope concerned is checked again against the results. Those carrying out the works receive the associated plans and prerequisites before starting.
Which areas are to be investigated, how deep do the proposed works extend and what knowledge already exists? This information comes before selection of a survey. Area size alone does not determine a suitable method. Existing installations and accessibility must also be considered so that the findings sought can be achieved under the actual conditions.
If it remains uncertain whether an area can be fully investigated, this question should remain visible in project planning. Where a clearance plan is required, it can coordinate further work with the construction sections. Not every outstanding detail immediately requires the same measure. However, it must be clear before which ground intervention a technical decision is needed.
Keep the regional plan, construction plans and explosive ordnance documents under their respective designations. A map extract helps orientation but does not answer every specialist question. Record the specific findings a document actually contains and the appendix associated with it. Specialist planners joining later can then identify the basis of the earlier assessment. Initial contact identifies the construction task and decision required. Existing explosive ordnance reports are checked with their complete area plans and appendices.
Different questions may remain for an initial site decision from those before excavating a construction pit. Describe the next step and the purpose for which you need specialist assessment. A suitable commission can be discussed from this. A commission that sounds as extensive as possible is not automatically more precise than a clearly defined investigation task. Where necessary, unresolved historical information is researched and assessed by specialists using suitable records and images. The required state aerial photograph analysis is arranged through the local office. Methods and investigation scope are selected according to target objects, ground conditions, intervention depth, interference and accessibility.
What begins as near-surface planning may later become a project with deeper foundations or utilities. Compare such changes with existing results again. It must be assessed whether their scope of findings remains sufficient. Neither an unchanged property number nor an earlier project name demonstrates that every subsequent construction approach has already been considered technically. Once prerequisites are clarified, the agreed survey or technically suitable supervision is carried out. Data and observations are interpreted and assessed in relation to the construction task described. Usable results, anomalous findings and outstanding questions remain distinguishable.
Before the respective groundworks, site management needs the associated documents and conditions still applicable. Hand reports over with their area plans. Uninvestigated subareas and limited findings must also remain identifiable. A shortened remark in a schedule should not replace this information. Documentation contains the scope addressed and the technical results. The subsequent decision identifies the additions or coordination needed before the next work step.
Document which plan revision was assessed and what underlies the investigation results. The technical basis thus remains accessible if the property is later transferred or project participants change. General suitability for a use does not establish a blanket finding about explosive ordnance in the ground.
FONTANA-EOD addresses the contractually agreed specialist tasks; it does not thereby assume the responsibilities of the municipality or state explosive ordnance disposal service. The BFR Kampfmittelräumung apply directly to federal properties. Their planning and documentation principles may serve as technical guidance for other projects, while local requirements must be considered separately.
FONTANA-EOD addresses the agreed specialist task for the defined site and its next groundworks in the Münster administrative district. Before work begins, accessible areas and results required are coordinated. If several development variants exist, their actual work status remains identifiable. Changes to plans or site conditions are checked before the work concerned. The report documents the work actually carried out and its limitations. Further site or construction planning receives a traceable indication of findings already usable and questions that remain to be clarified once construction is more specifically defined.
Discuss the investigation taskMethod selection starts with the knowledge lacking for the next actual groundworks. Specialist planning considers existing results, the ground and actual conditions. Available equipment or a general development designation does not suffice as the sole basis. Selection is justified for the ground volume concerned. Early exploratory works receive their own traceable scope even if final building or utility locations are not yet established.
Inaccessible areas and areas with limited interpretability are identified with their actual boundaries. Site management can allocate outstanding specialist work and necessary additions to them. A general statement about a potential development area does not replace this distinction. Planning and construction teams coordinate when a suitable investigation will be possible. Provisionally assessed areas and ground volumes actually investigated technically remain separate in the result status. Subsequent planning can use the respective appropriate findings without deriving broader evidence from them.
A new location, additional depth or different construction method is compared with existing results before the work concerned. Specialist planners receive the identifiable change to the earlier exploratory or development task. Their response and necessary additions are assigned to the ground volume concerned. A site initially considered may later lead to different building, utility or access-route volumes. The same area designation does not, by itself, confirm an unchanged investigation scope.
At handover, reports and associated plan appendices are supplied with the site, work status and actual specialist task identified. An overview may list the basis for site comparison separately from results of early groundworks. It does not replace the documented investigation scope. When development teams, designers, site management or companies change, outstanding use variants and ground volumes already investigated remain traceable. The subsequent construction task is checked against this knowledge rather than passing on a regional planning designation as complete documentation of the explosive ordnance question.
Regional planning describes broader spatial developments. A property investigation, by contrast, concerns a defined area and specialist question. These different purposes remain identifiable when reading the documents. Specific exploratory or construction works need appropriate local knowledge; a regional presentation cannot pre-empt those findings.
Understand investigation reports and their limitationsExploratory works and other preparatory activities may take place before the final construction design is established. Each intervention is therefore described and assessed separately. Later plans use the documented results but reassess their scope. Preliminary overall planning does not remove the need for specialist preparation of early groundworks.
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 documentationThe regional plan serves a broader planning purpose. Its designation is neither a conclusive statement on all prerequisites of an individual project nor an explosive ordnance investigation report. For proposed ground interventions, existing knowledge of the specific area must be considered separately.
The administrative district and planning area must be distinguished. In addition to Münsterland, the administrative district includes the Emscher-Lippe region. Therefore first check which plan actually concerns the property; the name Münster administrative district alone does not answer this question.
Before a decision, it can be established which knowledge exists and which specialist questions remain outstanding. The scope required depends on the proposed use and the respective decision stage. A general statement in a sales offer does not replace assessment of the underlying documents. Coordinate investigation needs with the specialist company in good time before proposed interventions, and official requirements with the local municipality. The enquiry should include the site plan, complete explosive ordnance reports with their maps and a description of the next groundworks.
Yes, planned exploratory works belong in specialist coordination as ground interventions. The measures required beforehand depend on the specific suspected hazard and the proposed work. A later date for building construction itself is no reason to postpone this question until then. The specialist process connects document assessment and required historical analysis with method selection, investigation, assessment and documentation. Further work is related to the results actually available. The results report, area plans and documented investigation boundaries are handed over together.
Stop work in the area concerned. Leave the object where it is, untouched and unmoved, move away and keep others away. Notify the police on 110 from a safe distance; their instructions must be followed.
The existing knowledge and outstanding questions are presented separately for each area. Few documents do not, by themselves, demonstrate less ordnance contamination.
According to current guidance from the Arnsberg district government, only local regulatory authorities are authorised to apply. The route for the specific project is therefore clarified through the municipality.
Method, area size, depth, interference and accessibility determine the effort required. Where there are several sites, their respective investigation tasks are described separately. Preparatory and follow-up work receive their actual service scope. The specialist service and result documents required are agreed for commissioning. Costs within the official procedure are clarified with the local office for the specific project.
Present alternatives with their respective knowledge and outstanding questions. Add the municipality, project address, cadastral parcels, current site plans and complete explosive ordnance reports. Mark which prerequisite for the approaching site decision has already been assessed and which specialist question still needs work. The sector overview explains typical interventions and the documents they require.
Identify early proposed exploratory works and groundworks with the available plans. Add the earliest groundworks, subareas not yet accessible and the people responsible for follow-up questions. Existing results from earlier exploratory works are attached with their maps and limitations.
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.
