Prepare explosive ordnance surveying in Mülheim an der Ruhr
For an explosive ordnance investigation, the affected area and proposed depths must be clearly shown on the plan. State which ground elevation the depths are measured from. FONTANA-EOD supports preparation of your project in Mülheim an der Ruhr and documents commissioned investigations. Existing results are compared with the proposed groundworks.
Enter the excavation and other groundworks.
Identify the starting elevation for every depth.
Mark the valid version and changed areas.
Assess the construction project
State each depth with its starting elevation
A depth is unambiguous only with its elevation reference. For your project in Mülheim, we compare position, planned interventions and existing investigation results. Unknown earlier ground conditions remain identifiable as missing information and are not inferred from today’s surface. Agree the necessary applications and investigations before the first ground intervention they concern.

Prepare traceable area and elevation details for Mülheim
According to municipal information, the local regulatory authority is the receiving authority; the form describes forwarding to the explosive ordnance disposal service of the Düsseldorf district government. The application and map guidance require clear identification of the area. Relevant depths and ground references are also clarified for your own project. This does not imply that shallower interventions are generally safe. Mülheim an der Ruhr is an independent city in North Rhine-Westphalia and belongs to the Düsseldorf administrative district.
Projects in Altstadt and the city centre, Broich, Styrum, Speldorf, Dümpten, Heißen, Saarn, Holthausen, Menden or Ickten require the project address and site plan. Describe existing and planned use, affected structures, construction sections and their ground and depth references. For bridge, riverbank or infrastructure works, access, working volumes and available investigation areas are also clearly identified.
FONTANA-EOD has a location in Wesseling. For projects in Duisburg, Essen, Oberhausen, Ratingen or Heiligenhaus, state the respective municipality and precise project location. These neighbouring cities have their own municipal responsibilities. For other projects in the western Ruhr area, the procedure and specialist task are clarified using the actual location and proposed groundworks.
Local context
Local application and historical information in Mülheim
Application documents and former uses
The City of Mülheim an der Ruhr identifies the local regulatory authority as the receiving authority for aerial photograph analysis relating to a planning application or construction notification. The application form provided records, among other things, the property, cadastral parcel, use and type of construction measure. Its map guidance requires a clearly defined investigation area with identifiable spatial context.
The Mülheim an der Ruhr City Archives document the air raid on the night of 22 to 23 June 1943. For present-day projects, historical indications are related to the specific construction area and existing building records. Former industrial, commercial, production and storage sites, railway and shunting areas, and later redevelopment or development areas are considered using their actual history of use. For city-centre infill, rebuilt residential and mixed-use areas and later service or residential uses, available information on built-over, filled or reorganised areas is compared. For bridges and riverbanks on the Ruhr, the structure, access and bank protection are considered together with the proposed interventions.
Relate depths to the appropriate ground condition
Municipal guidance relates the depth of a ground intervention to former ground conditions. Therefore check whether your elevations use the reference required by municipal guidance. Clarify the local application requirements for your project with the regulatory authority using current guidance. A depth figure alone does not replace investigation or assessment of the area. The municipal website relates the 80-cm threshold to the natural ground of 1945. For possible omission of an application for shallower interventions, it also specifies that no ground-combat area may be affected. The form asks about at least 80 cm, while the website refers to deeper than 80 cm. Therefore clarify boundary cases, the relevant ground reference and local assessment with the Ordnungsamt before affected works. Available or missing information on the former ground level remains identifiable in the documents.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For commissioned activities, the applicable specialist requirements and questions of permits, qualifications and responsibilities are clarified. The scope of services actually proposed is decisive. A general company description does not replace assessment of whether the respective tasks and interfaces are appropriately described for the specific project. Company authorisation, competence and appointment of responsible persons are assigned to activities requiring a permit. The prerequisites for the narrowly limited private North Rhine-Westphalia exceptions are checked before a corresponding agreement.
Link occupational safety to the construction sequence
Risk assessment, work areas and communication must fit the proposed activities. Specialist ordnance work is coordinated with the other construction work. Site organisation, traffic safety and further technical specialist assessments retain their own responsible parties. Joint coordination brings information together without equating different tasks. Employers assess the risks of their respective activities and agree the protective measures required at interfaces. If conditions change, the assessment is reviewed for the affected work. Information routes and contacts must be clear to those involved on site.
Use technical findings correctly
A measurement anomaly first requires specialist assessment; it is not identified as ordnance solely because of how it is displayed. For an actually suspicious object, the prescribed reporting routes and measures of the competent authorities apply. Investigation reports identify the scope investigated and its limitations so that results are not transferred to unassessed areas or later plan changes. If a suspicious object is found, work in the affected area stops and distance is maintained. The object remains untouched. Notify the local public order authority or police immediately; in an acute situation, call the police on 110. The competent authorities undertake further securing and specialist handling.
The City of Mülheim an der Ruhr describes the local explosive ordnance investigation procedure. The application with map guidance identifies the property, construction measure and investigation area using the map information required.
The investigation objective, area and method are compared with the principles of clearance planning and the specialist geophysical principles of the BFR KMR. Handover of results is prepared with reference to the BFR KMR documentation guidance. For task-specific occupational safety, the DGUV guidance on explosive ordnance clearance is consulted. Permissible private activities in North Rhine-Westphalia are related to the requirements of the KampfmittelVO NRW and official North Rhine-Westphalia guidance.
The BFR KMR are used as technical guidance; locally applicable requirements and responsibilities must be clarified 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, the requirements of the exceptions under the KampfmittelVO and the official guidance are related to the construction task. The narrowly defined exceptions concern downhole detection in specialist foundation engineering and explosive ordnance clearance during construction under the respective applicable conditions. The site conditions assessed by the state and authorisations required must be in place. Specific indications of ordnance contamination are handled through the responsible state procedure. Before opening up a location indicated as suspicious, the appointment is agreed with the responsible municipal authority; any notifications required under explosives legislation must also be observed.
Working together
Distinguish the tasks of client, designers and specialist contractor
Client and operator
The client describes the project and provides the existing project documents. The operator adds the requirements for use, access and timing. A named contact coordinates the assigned tasks with those responsible. Before commissioning, a clear record is made of which information is missing, who will obtain it and which decision the results are intended to inform.
Planning and construction management
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.
Specialist company and competent bodies
The private explosive ordnance specialist company addresses the agreed investigation and documentation scope permissible for the activity. Clarify the local application and necessary state aerial photograph analysis with Mülheim an der Ruhr’s Ordnungsamt. It forwards the documents to the KBD Rheinland of the Düsseldorf district government and communicates the result with any necessary measures. Designers relate these requirements to the specific construction task. FONTANA-EOD’s report documents the private specialist service performed, its areas addressed and limitations of findings. Responsible project participants connect the documented status with the next construction phase.
Investigation task
Which specialist task comes next?
Read existing results spatially
Check a report’s investigated area, depth reference and technical limitations. Only then can comparison with today’s construction task take place. A property address or single depth figure is insufficient. Unclear underlying information is incorporated as an outstanding question in further coordination.
Assess historical documentsDetermine the findings needed for the specific project
Structural elements, intervention depths and measurement conditions frame the technical task. A municipal application prerequisite is not evidence of an actually investigated ground volume. Possible methods and permissible private activities are checked separately. Necessary official processing remains distinct from the specialist service.
Compare investigation methodsProject types
Document position, elevation and plan version together
Distinguish different starting elevations
If the ground surface has changed, present-day and earlier depths may describe different ground volumes. Therefore identify the level used and its underlying information. Existing elevation plans and cross-sections assist identification. Missing earlier information is not replaced by an apparently precise but unsubstantiated figure. Compile today’s surface, proposed excavation formation level and available earlier terrain information with their respective dates or versions. Where fill, excavation or subareas at different elevations exist, state what each depth refers to. Survey data and information reconstructed from records retain their respective provenance and accuracy.
Document findings and their limitations
Label subareas clearly
Each working area should be identifiable in the documents. Use traceable labels for excavations, utility sections and additional foundations. Identification must remain understandable after a plan change. A result can then relate to the area actually covered without being extended to other parts of the property.
Specialist services and investigation tasksKeep the map and construction plan together
The area representation used for the application and technical plan serve different tasks. Establish their spatial relationship. A suitable application map does not replace information on proposed structural elements and depths. Conversely, a construction plan lacking adequate surrounding context may not fulfil official area identification requirements.
Document findings and their limitationsPreparation
Prepare the scope and commission together
For commissioning, the construction task, existing findings and planned interventions are considered together. Areas, depths and reference elevations are represented so that designers and the specialist company can identify the same working areas.
Establish what needs to be known before commissioning the work
The commission first needs to clarify which decision is to be prepared. Is the task an initial assessment of existing documents, investigation of a particular area, or further work on a finding already assessed? These tasks require different evidence. A general wish for safety does not yet describe an executable investigation scope. The enquiry therefore identifies the groundworks, location, depth and findings available. Suitable specialist work and results documents needed are agreed on this basis. For a quotation, provide complete reports with their plan attachments and the current construction design. Identify the findings required for the next contract award. Where building and infrastructure works are commissioned separately, shared connection points and outstanding investigation areas are explicitly assigned.
Define the specialist taskCoordinate preparatory work with the investigation
The access and measurement conditions required are clarified before the appointment. These may include areas to be kept clear, available utility information and coordination with other trades. The preparatory work actually needed follows from the chosen method and site. Surface changes or additional ground interventions are not undertaken independently merely to prepare a measurement. Their sequence is agreed with specialist planning and those responsible. Identify foundations retained, utilities and the areas actually available at the appointment. The type and scope of preparatory services needed are agreed with those responsible. If additional working areas are required, their location is compared with the plans before investigation. Changes to the ground follow the specialist sequence clarified for them.
Clarify preparatory work in the programmeAgree a clear scope and schedule
A reliable sequence distinguishes work already technically clarified from outstanding prerequisites. If an area will be only partly accessible, commissioning must consider this. Results handover and assessment also require time in the construction sequence. Costs and dates are agreed for the specific specialist task and actual execution conditions. Specific coordination connects the described scope with access, documents, execution conditions and decision timing needed. Costing considers area, depth, method, accessibility, assessment and documentation. General guidance in the municipal application gives approximately two to four weeks for processing by the explosive ordnance clearance service. This administrative information is compared with the current procedural status. Fieldwork, necessary preliminary services and results handover receive a separately agreed sequence.
Discuss the scope and scheduleTasks at the site
Show groundworks with position and elevation reference
01
Distinguish the property from the construction area
A cadastral parcel does not automatically describe the full extent of planned groundworks. Mark other affected areas alongside the main excavation, such as a new utility line or additional foundation. Identify works included in the enquiry and areas not affected. Give interventions clear labels and their respective planned maximum depths. For connected projects, show the excavation, utility sections and other working volumes distinguishably. The area covered by an existing result is compared with this boundary.
02
Identify the elevation reference
State the level from which a depth is measured. Existing elevation plans, cross-sections and terrain change information assist identification. Note where earlier ground conditions are not sufficiently known. Mark estimated elevations as estimates. Identify the reference point with the plan version and provenance of the elevation information. For shared comparison, the levels used are traceably related to each other. Earlier elevations not adequately substantiated are clarified with specialist planners as missing underlying information.
03
Identify subareas unambiguously
Where there are several working areas, each subarea needs an unambiguous label. Designers, authorities and specialist companies can then relate questions to the same area. A project address alone is insufficient. Structural elements, depths and later extensions must also be identifiable in the report.
04
Identify plan changes
If an excavation changes or another intervention is added, participants must be able to identify the applicable plan. Describe the change against previous documents. Then check whether existing results also cover the new design’s areas and depths.
Project documents
Documents that establish the next step
Relate land surveying and specialist planning
Position and elevation information must be compatible for comparison. Pass on the underlying information and plan versions used. Different reference points are clarified before defining services. A shared representation assists identification but retains the original documents’ limitations and uncertainties. Comparison may require today’s ground level, planned excavation formation level and earlier ground conditions in the same plan. The data used receive clear provenance and a spatial reference. The client, surveyors and specialist planners agree which reliable information already exists and what must be supplemented before investigation.
Pass new plan versions on explicitly
If terrain, excavation or foundations change, the difference from the previous version must be identifiable. Affected participants receive the current plan and corresponding information. An existing report remains limited to its documented scope. For completed clearance work, the clearance record with areas treated, actual clearance scope and results is related to the corresponding site plan and elevation reference. Whether additions are needed is assessed using the change. Mark changed areas, depths or elevation references and identify the difference from the previous design. The specialist company receives the complete earlier report and current plan version. Supplementary investigations are established using the actual difference and findings needed.
Construction sequence
Coordinate investigation and construction sections
Before compiling the application
Check clear area boundaries and map suitability against current municipal guidance. Add details of the actual project. Provide the depths and reference elevations needed for specialist planning traceably. Missing information is identified early so that questions can be addressed specifically.
Before a changed ground intervention
Compare the new design with previous result boundaries. A different ground elevation may change the meaning of an unchanged depth figure. Record the reference points used. Further work is clarified before the affected works rather than extending older findings indiscriminately to the new design.
Method selection
Select methods according to the task and survey conditions
Historical records and aerial photographs
Historical aerial photograph assessment and other old records help place the basis for suspicion in its spatial context. The available images, their evidential value and the limits of the area considered matter. The absence of an identifiable indication must be distinguished from a technically surveyed ground area. The assessment is considered together with the planned intervention and other available findings. It can support the choice of a survey, but is not a measurement of the present-day subsurface or confirmation for all future works.
Understand aerial photograph assessmentMagnetometric survey
Magnetometric methods detect magnetic anomalies. Whether they can address the specific survey task depends, among other things, on the expected objects, ground conditions, interference and required survey area. Fences, utilities or existing structures may affect interpretation. A measurement signal is therefore not described as ordnance solely because of its strength. Method, interpretation and any further investigation are planned as a connected specialist task.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations can be suitable for particular metallic targets and site conditions. Their suitability must be explained for the task, rather than inferred simply from the availability of equipment. Interfering installations, accessible areas and the findings required must also be considered. Results are documented with their location and survey conditions. The specialist assessment determines whether a supplementary method is needed; this remains a project-specific decision.
Understand electromagnetic surveyingGround-penetrating radar
Under suitable conditions, ground-penetrating radar can provide information about subsurface structures and reflections. Ground conditions, moisture, installations and the particular survey task affect interpretability. An anomaly is not automatically ordnance, and an area with no apparent anomalies is not general evidence for arbitrary depths. The specialist interpretation and its limits are documented with the instruction. A survey for another purpose is not adopted without checking as ordnance evidence.
GPR and limitationsDeep-ground and downhole surveys
For deeper groundworks, it may be necessary to establish whether a surface investigation can provide the required findings or another approach is needed. Preparation includes the location, depth, borehole layout and existing services. Creating access for the investigation must also be properly planned by specialists. A general depth figure or standard grid cannot replace that work. Findings remain limited to the areas actually investigated and the method used.
Prepare deep interventionsSurvey during construction
If a necessary preliminary investigation cannot be completed, the specialists assess whether a planned approach during construction is suitable. This includes coordinated investigation, interpretation and communication of findings within the intended work sequence. Visual observation of excavated material is not an interchangeable substitute for a necessary survey. Site management needs a clear description of when specialist work will take place, how new findings will be handled and which areas remain unresolved.
Agree the approach during constructionTechnical assessment
Investigations required by the planned interventions
Compare aerial photograph analysis with today’s plans
A historical aerial photograph analysis must be read with the areas and documents used for it. Its relationship to today’s plans must be traceable. Describing a former condition does not alone answer how current foundations, a utility intervention or excavation support can be investigated properly.
Investigation objective and measurement conditions
The survey is prepared according to the investigation objective, findings scope required and local measurement conditions. The area plan provides a basis for method selection. Accessibility and possible limitations must also be considered. The depth that can actually be investigated requires technical clarification.
Piles, excavation support and other deep interventions
For piles, excavation support or other deep interventions, questions different from those of an area-based surface survey may need answering. Technical selection and the legally permissible service scope remain project-specific. North Rhine-Westphalia regulates certain private downhole detection and explosive ordnance clearance activities during construction separately; mere visual observation does not replace necessary detection.
Next steps
Compile documents for the enquiry
Identify the property
Coordinate the address, cadastral parcels and plan documents. For the initial project enquiry, discuss the construction task, areas, depths and next decision needed. Demolition, connections and temporary construction conditions are included alongside new buildings. Known utilities and the respective current plan version are identified.
Enter interventions
Describe working areas, structural elements and depths with their elevation references. Check official information, aerial photograph analyses and investigation reports for plan version, spatial coverage, depth reference and outstanding questions concerning today’s task. The scope actually documented is decisive. Missing or conflicting information is identified with its relationship to the planned intervention.
Supplement historical information
The required state aerial imagery analysis is initiated through the municipal procedure provided locally. If the available findings need supplementation, further historical research is carried out for the specific question. Available aerial imagery, maps and records of use are professionally analysed and related to the present-day construction site. The findings feed into further investigation planning.
Include existing findings
Relate existing assessments and reports to the respective areas. The specialist company selects the technically suitable approach using the investigation objective, grounds for suspicion, ground composition, interference and accessibility. Preliminary services and the permissible activity scope are clarified. Investigation areas and interfaces are coordinated with the construction sequence.
Investigate and assess results
Within the agreed and permissible scope, the defined areas or points are investigated using a suitable method. The data collected are recorded with location, depth reference and site conditions. Specialist personnel assess results and anomalies according to the investigation objective, method and interference. A measurement anomaly is not yet identified ordnance. Further clarification required and areas not adequately investigated are identified; local reporting procedures apply if ordnance is found.
Update changes
Have deviations reassessed technically before further works. Work performed and its technical assessment are documented in a report with the corresponding site and plan appendices. Methods, areas addressed, depth references and limitations of findings remain traceable. The client and designers compare this status with the next construction phase. Additional specialist works or official steps are identified before the interventions they concern.
Documentation
Identify the investigated area in the report
Findings and their scope
Pass investigation reports on with their corresponding plans. These must show which areas were investigated, by which method and which limitations exist. Subareas not addressed must be marked. If plans change, it can then be checked whether the existing result covers the new intervention.
Project responsibilities
FONTANA-EOD documents the commissioned specialist service within its actual scope. The documents replace neither an official decision nor a separate assessment of changed construction works. The BFR Kampfmittelräumung provide technical principles for this; outside their direct federal scope, they serve as guidance alongside relevant local requirements.
Working approach
How FONTANA-EOD works
Document the agreed specialist service clearly
We assess the planned groundworks against the available documents and their design revision. Before attending site, we agree with you what needs to be investigated, which areas are accessible and what findings are required. If the design or site conditions change, we check whether the agreed scope remains appropriate. The report states what was actually investigated and the limits of the findings. This allows designers and site management to see which findings they can use and where questions remain.
Discuss the investigation taskThe task before the equipment
We first establish the investigation objective: which question must it answer? We then select a technically suitable method. The availability of a particular device or experience on a similar neighbouring site is not enough to justify the choice of method on its own.
Keep limitations visible
Inaccessible areas and limited conclusions are identified. They do not disappear into a total area figure. Designers and site management can then decide specifically which areas still need attention and when a suitable survey becomes possible.
Clarify changes before intervening in the ground
A new location, additional depth or different construction method is compared with previous results. A familiar project name does not replace this comparison. Feedback is provided before the affected work so that an outstanding question can be included in the sequence.
Hand over the report and plan together
The technical conclusion remains connected to its location references and appendices. A brief summary helps orientation but does not replace the documented survey scope. This basis is retained even if site management or contractors change.
Understand the results
Use technical statements for the next decision
The same depth figure may mean different things
The spatial findings depend on the starting elevation. Identical figures before and after terrain changes may therefore describe different areas. State the reference explicitly and include existing underlying information. An unknown earlier elevation remains an information gap pending clarification.
Understand investigation reports and their limitationsA map marking must be unambiguous
The affected area should be traceably connected with the property and its surroundings. Unclear circles or address details alone may be insufficient. Current official requirements are observed for the application. Technical result boundaries are subsequently documented with their own actual scope.
Understand the service scopeDesign and findings
Documents for the next construction decision
Historical evidence and the current design
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.

Process and documentationQuestions from planning
Questions about areas and elevation references in Mülheim
Where is the aerial photograph analysis application submitted?
The city identifies the local regulatory authority and provides an application form. The current requirements described there for the specific project are decisive. An enquiry to FONTANA-EOD does not replace that official procedure.
Why is the property address alone insufficient?
It does not yet identify the subarea to be investigated unambiguously. Technical preparation needs the planned groundworks and their spatial scope to be traceable. A marked site plan connects the enquiry with the interventions actually proposed.
Why does a depth’s reference matter?
The same figure measured from different starting elevations may describe different ground volumes. Therefore identify the level used and existing knowledge of terrain changes. Uncertainties are agreed before the investigation based on them.
Does an older report also apply to a changed design?
This must be checked using the documented investigation scope. Additional areas, different depths or a changed construction method may require supplementary technical assessment. Even if the project name is unchanged, the earlier evidence applies only within its documented scope.
What should I do if I find a possible item of ordnance?
Stop work in the affected area immediately, do not touch or move the object, and keep your distance. Notify the police on 110 and follow official instructions. Do not attempt to expose, investigate or recover it yourself.
How is an estimated earlier elevation treated?
It is explicitly labelled as estimated and its basis stated. Whether it is sufficient for the intended technical findings must be clarified before a decision is based on it.
Can a current construction plan replace the application map?
This depends on current municipal requirements. Mülheim’s map guidance requires clear area boundaries with spatial context and visible cadastral parcel boundaries.
Which costs and lead times need clarification before commissioning?
According to municipal guidance, the state of NRW bears aerial photograph analysis costs. A private investigation commission, preliminary services needed and further measures are allocated separately. Costing considers area, depth, method, accessibility, assessment and documentation. General guidance in the municipal application gives approximately two to four weeks for processing by the explosive ordnance clearance service. Coordinate current procedural status and complete underlying information with the proposed specialist works date.
Project enquiry
Prepare investigation for your project in Mülheim
Add the elevation reference
For each depth, identify the level used and available information on earlier terrain changes. The city relates the application question to the natural ground of 1945. Record which earlier and present-day terrain information exists and where fill or excavation is known. Proposed excavation formation levels, piles, support or utility excavations receive their respective references to the surface and current design.
Mark areas clearly
Send suitable maps, current construction plans and reports with clearly labelled subareas and plan versions. To compare two versions, provide the previous and current site plans and cross-sections with elevation references and complete investigation reports. Changed structural elements, areas and depths are explicitly identified. Municipal map guidance requires visible cadastral parcel boundaries, at least two legible street names and a clearly defined investigation area. A postal address or cadastral parcel numbers alone do not provide this map representation. The construction plan and application map are assigned their respective purposes.

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.
