Explosive ordnance surveying and clearance in Solingen
If an extension involves new utility lines, chambers or additional foundations, these also belong in the groundworks planning. For your project in Solingen, FONTANA-EOD supports the preparation and documentation of commissioned explosive ordnance investigations. The areas actually affected, existing evidence and the conditions in your official decision are decisive.
Describe the proposed groundworks.
Show the new foundations and existing building on the plan.
Check official decisions for conditions that remain outstanding.
Assess the construction project
Record the extension with all ground interventions
An extension may involve new foundations, utility lines and chambers in different areas. For your project in Solingen, we compare these interventions with existing results and the specific conditions in the official decision. Previous use of the building alone does not establish that the newly affected areas have been investigated.
Project site
Connect the site with the specific construction task
Connect Solingen’s application procedure with the specific construction project
The municipal information sheet names the Stadtdienst Ordnung as the receiving authority and describes forwarding the documents to the explosive ordnance disposal service of the Düsseldorf district government for aerial photograph analysis. The project description should make the groundworks clear in particular. The conditions in your own official decision remain decisive for execution. Solingen is an independent city in the Düsseldorf administrative district in North Rhine-Westphalia. For enquiries from Mitte and the city centre, Ohligs, Aufderhöhe, Merscheid, Wald, Gräfrath, Höhscheid or Burg an der Wupper, provide the specific project location. For Wuppertal, Remscheid, Leverkusen, Langenfeld, Hilden, Bergisch Gladbach and other places in the Bergisches Land or Rhineland, the relevant municipal responsibility is established separately.
Local context
Application and planning permission conditions in Solingen
Solingen application with a specific description of the groundworks
Solingen’s information sheet on explosive ordnance disposal names the Stadtdienst Ordnung as the receiving authority for applications. The required information includes the building plot and a brief project description, particularly of the groundworks. According to the municipal guidance, the documents are forwarded to the state explosive ordnance disposal service of the Düsseldorf district government for aerial photograph analysis.
Consider the conditions in the actual official decision
The information sheet also notes that planning permission may include a condition precedent concerning clarification of the explosive ordnance situation. The content of the specific official decision is therefore decisive for planning. Describe the proposed groundworks specifically and check the conditions before starting them.
The municipal anniversary chronicle describes the severe air raids of 4 and 5 November 1944 and the destruction of large parts of the city centre. For present-day sites, historical findings are considered alongside later construction conditions and the specific intervention. For older industrial, craft, storage and operational sites, railway and transport corridors including station and track surroundings, or densely built residential areas, documented former uses, reconstruction, changes of use and later ground alterations belong in the document review. On slopes, in valleys, and where fill or embankments are present, documented terrain changes are related to the proposed intervention. Retaining structures, redevelopment and other infrastructure projects are described with their actual required working areas and depths. This does not yet constitute evidence of a technical investigation of a particular area.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For the commissioned activities, the relevant technical requirements and questions of permits, competence certification and responsibility are clarified. The actual planned service scope is decisive. A general company designation does not replace checking that the tasks and interfaces are described appropriately for the specific project.
Link occupational safety to the construction sequence
The risk assessment, working areas and communication must fit the planned activities. Explosive ordnance specialist works are coordinated with the other construction works. Operational organisation, traffic safety and other technical checks retain their own responsible parties. Joint coordination brings the information together and assigns tasks and decisions to the respective competent participants.
Use technical findings correctly
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.
Procedure at the site: City of Solingen: information sheet on explosive ordnance disposal.
Planning and documentation: BFR KMR: principles of clearance planning · BFR KMR: geophysics · BFR KMR: documentation · North Rhine-Westphalia KampfmittelVO: Section 3 in particular · KBD North Rhine-Westphalia: guidance for downhole detection and explosive ordnance clearance during construction · DGUV: explosive ordnance clearance FAQ
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.
Private works are subject to the exceptions under the KampfmittelVO and the requirements of the official guidance. The exceptions concern, in particular, downhole detection as part of specialist foundation engineering and explosive ordnance clearance during construction under the conditions laid down by law. Private explosive ordnance clearance during construction requires that prior investigation using recognised explosive ordnance detection methods is not possible. A relevant factor is also the state explosive ordnance disposal service's assessment that there are no specific indications of ordnance contamination on the site concerned. All further spatial, technical and organisational requirements are clarified for the specific activity. The competent authorities decide on the official appointment.
Working together
Allocate tasks within the construction project
Client and operator
The client describes the project and provides the available project documents. The operator adds requirements relating to use, access and scheduling. The participants agree their respective tasks and decision-making responsibilities. A coordinating contact person brings the project information together. Before an appointment, it is recorded clearly which information is missing, who will obtain it and which decision the result is intended to support.
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 carries out the agreed permissible investigation and documentation scope. Authority requirements and decisions are clarified with the respective competent bodies. The documents needed for a specific procedure depend on the site and project. The technical report documents the specialist service performed, including areas, depths and limits of its conclusions. Its applicability to further groundworks is checked against the specific intervention.
Solingen’s information sheet names the Stadtdienst Ordnung as the receiving authority for explosive ordnance enquiries. The state explosive ordnance disposal service at the Düsseldorf district government carries out the technical processing initiated by the authorities. The tasks and requirements of the responsible authorities are established before permissible private specialist work. Official decisions and emergency hazard prevention measures are the responsibility of the competent authorities.
Investigation task
Which specialist task comes next?
Relate existing findings to the extension
Read earlier assessments and reports with their maps, underlying information and limitations. The current intervention is compared with that actual scope. A document concerning the existing building may provide important information without covering the new extension. Areas and depths still unresolved are identified before the service is defined.
Assess historical documentsAgree the required specialist task specifically
The method and investigation depend on the required findings and actual measurement conditions. Existing buildings and installations may be relevant. The conditions for private work in NRW are also checked. A service during construction is not inferred solely from a wish to start building at short notice.
Compare investigation methodsProject types
Plan the main structure and additional interventions together
Distinguish the existing and new parts of the building
Clearly mark the proposed extension and existing structural elements. This includes the foundation work actually planned, with its position and depth reference. An older report is checked to establish which area it covers. Joint use of the two parts of the building does not extend its documented scope of findings.
Also show the connection between the new structure and the existing building. The planned working area of an excavation may extend beyond the eventual footprint; a connection may pass through a part of the site previously used differently. For comparison, describe these ground volumes with their position, depth and relevant ground surface. The complete appendices are checked to determine which earlier results can be used. Outstanding questions are related to the structure actually being added.
Specialist services and investigation tasks
Add ancillary works to the intervention plan
An additional foundation or utility chamber may lie outside the new main excavation. Show each of these works separately with its position and depth. A general term such as extension may conceal such tasks. The investigation is related to the complete construction task so that no area actually required is subsequently overlooked.
An extension may, for example, include new service connections, relocated drainage or an additional foundation outside the main structure. Mark the intended sections on the site plan and state which depths have already been established. If a utility route is still undecided, communicate the relevant option as the current planning status. The next specialist service can then be related to the space actually intended. If the plan changes later, compare the additional areas affected with the existing findings again. Necessary investigations and protective measures are clarified before preparatory ground interventions.
Provide specialist supervision of excavation
Consider changes in ground level
If the ground is to be excavated or filled, the initial condition and the plan must be distinguishable. A cross-section can clarify the reference for the proposed depths. Missing earlier information is explicitly identified. The new surface level must not silently be used as the reference for an older investigation report.
On a site on a slope or in a valley, excavation, fill and retaining structures may affect different ground volumes. Therefore state the existing surface and proposed new levels with an unambiguous reference. An older report must make clear which terrain or elevation level its depths are measured from. If that information is missing, clarify the specific uncertainty before further use. The documentation of the new investigation records the surface actually used as its reference. This keeps the original construction condition, completed specialist work and subsequent terrain changes distinguishable for comparison.
Document findings and their limitationsPreparation
Prepare the scope and commission together
Historical preliminary assessment, technical investigation and specialist work during construction answer different project questions. The permissible private activity under the specific North Rhine-Westphalia procedure is clarified with the information objective and necessary authority involvement before an agreement.
Establish what needs to be known before commissioning the work
First establish which decision the commission needs to support. Is the task an initial assessment of existing documents, an investigation of a specific area or examination of an anomaly that has already been assessed? These tasks require different evidence. A general wish for safety does not define an investigation that can be carried out. The enquiry therefore specifies the groundworks, location, depth and available findings. Suitable specialist work and the required reporting are then agreed on that basis.
Define the specialist taskCoordinate preparatory work with the investigation
Required access and survey conditions are clarified before the site visit. This may include keeping areas clear, obtaining service information and coordinating with other trades. The method and site determine which preparations are actually needed. Changes to the surface or additional groundworks are not undertaken unilaterally simply to prepare for a survey. Their sequence is agreed with the specialist designers and responsible parties.
Clarify preparatory work in the programmeAgree a clear scope and schedule
The scope of private specialist work is agreed using the project documents, actual execution conditions and permissible activity. Necessary preparatory works, investigation, evaluation and documentation are described transparently. Costs and dates are related to these prerequisites and the required coordination. Changes to the construction plans are checked against the agreed contract before work is extended.
Discuss the scope and scheduleTasks at the site
Record the extension, utility lines and terrain changes on the plan
01
New foundations beside the existing building
Mark the new foundations and the groundworks they require separately from the existing building. For an extension, it should be clear which area existing reports relate to. Previous use of a building does not in itself constitute an investigation result for a newly planned intervention.
02
Utility lines, chambers and additional foundations
Additional connections, chambers or foundations may lie outside the main excavation. Include these works in the description if they are part of the project. The investigation plan must also cover these groundworks and must not be limited to the main building.
03
Excavation, fill and retaining elements
If levels are to be changed or retaining elements built, distinguish the existing condition from the proposed intervention. Describe the affected areas and depths. Show the planned ground alteration in a cross-section or another suitable illustration. The site address alone is insufficient.
04
Outstanding conditions before construction starts
Bring together the relevant conditions from official decisions, technical statements and the agreed investigation scope. Record what has already been clarified and which response remains outstanding. A planned construction start does not remove these requirements.
The first groundworks may precede the extension itself, for example for a connection or necessary site access. Therefore describe these works during preparation. Their required investigations and official determinations are related to their own intervention. If further state processing remains outstanding, it remains visible as an open task in scheduling. A permissible private specialist service is agreed with its specific scope. The client, designers and contractors receive the documentation relevant to their next works and the limitations they must observe.
Project documents
Documents that establish the next step
Read the construction plan and official decision together
Relate the conditions in the specific official decision to the proposed execution. Record which documents are required and which response remains outstanding. A general information sheet provides guidance but does not replace your own official decision. Clarify uncertainties with the responsible authority before the relevant works.
Mark in the project file which requirement comes from the official decision and what findings a technical report actually provides. The report and plan appendices document the area, depth and task addressed; read them together with the construction plan used for execution. Any official response still required remains traceable as a separate process. Agree with the responsible authority which document must be submitted to clarify it. The company describes the agreed specialist service and its results. After clearance work, the clearance record, including the scope, results and remaining limitations, supplements the evidence chain for the area actually treated and the corresponding plan version. Whether a specific official requirement has been fulfilled is decided in the relevant procedure.
Communicate changes before execution
A changed foundation or an additional utility line may affect areas different from those in the previous plan. Pass on the updated version with a description of the change. The existing results are then reviewed. A date already agreed does not mean that the changed task has been fully clarified technically and with the authorities.
When issuing a new drawing, identify the version it replaces and the interventions actually changed. An additional foundation, deeper chamber or different route may create its own investigation requirement. Unchanged sections continue to be managed with the evidence applicable to them. Clients and specialist participants agree which supplementary work is required before the affected works and how it is commissioned. After execution, older and new result areas are brought together in the documents while remaining distinguishable. The next company receives the related reports with the status of remaining open tasks.
Construction sequence
Coordinate investigation and construction sections
Before completing the extension plans
Record the main excavation, new connections and ancillary works together. Include existing results and the relevant conditions from official decisions. This shows which task remains open and which documents are missing. An initial sketch can start coordination but does not replace an adequate representation of the actual ground interventions.
Distinguish established structural elements from design options still open. State which groundworks are planned first and whether some areas will only become accessible later. If a facility or building remains in use during construction, communicate the actual routes, access arrangements and agreed working windows. Investigation planning can then identify the accessible sections and outstanding tasks. The quotation describes the permissible agreed scope and the results documentation required. The technical assessment considers the available findings and measurement conditions; additional tasks are agreed with the participants before they are carried out.
Before the first groundworks appointment
Compare the proposed scope of work with the available results and the status of official processing. Also check early connection or preparatory works. Bringing them forward does not remove any requirement. The contractor receives the complete documents and the limitations relevant to its task.
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 investigation task depends, among other things, on the expected objects, subsurface conditions, interference and investigation area required. Fences, utilities or existing structures can affect interpretation. A signal is therefore not classified as explosive ordnance solely on its strength. The method, interpretation and any further investigation are planned as a connected specialist task. Magnetometry measures the magnetic field passively. The magnetic effect of the target object is decisive; electrical conductivity alone does not establish its detectability by this method.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations may be suitable for certain metallic target objects and site conditions. Suitability is justified for the particular task rather than inferred from the mere availability of an instrument. Interfering installations, accessible areas and the required conclusion must also be considered. Results are documented with their locations and investigation conditions. Whether a supplementary method is needed follows from technical assessment and remains a specific project decision. Transient electromagnetic methods, or TDEM, evaluate the time-dependent electromagnetic response of conductive objects. The method is selected according to the investigation objective and actual measurement conditions.
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
What existing documents and measurements establish
Compare aerial photograph analysis with the construction plan
The historical aerial photograph analysis is considered together with the project plan and other available documents. The findings it contains, the area covered and any further steps stated are decisive. Read the document’s underlying information and limitations; its title alone does not establish whether it covers the planned interventions.
Measurement conditions beside buildings and installations
For a survey around existing buildings and installations, the actual measurement conditions require technical assessment. Whether the required findings can be obtained, and with which method, is decided for the specific project. An area only partly accessible must not appear in the result as fully investigated. Where measurement capability is limited, a suitable supplementary investigation or permissible specialist supervision during construction is agreed on technical grounds. Measurement limitations and areas not yet investigated remain identifiable in the report and plan appendices.
Prerequisites for clearance during construction
A clearance operation for explosive ordnance during construction is not a general substitute for an investigation that could have been performed beforehand. Special requirements apply in North Rhine-Westphalia. Merely watching excavation does not replace proper explosive ordnance clearance. The name excavation supervision alone does not establish whether the proposed method is suitable.
Next steps
From construction documents to a documented investigation
Record the groundworks
Include the main structure, connections and ancillary works on the plan. Send the project address, investigation question and complete existing documents for comparison.
Review the underlying information
Compile existing findings and the specific conditions in the official decision. Check the documents for currency, spatial correspondence and gaps. Where historical questions remain open, carry out the necessary source research and aerial photograph analysis and relate them to the present-day intervention.
Agree the specialist task
Agree the objective, method and limitations of the commissioned investigation. The suitable method depends on the findings sought, intervention depth, utilities, ground composition and measurement conditions. Responsibilities and prerequisites for execution are clarified before work.
Perform the agreed investigation
The survey or investigation during construction appointed under North Rhine-Westphalia's requirements is carried out in the agreed areas and points. Measurement data and observations receive traceable location and elevation references. Uninvestigated areas, restricted access and relevant interference are recorded.
Assess survey data and findings
The collected data and findings are evaluated against the investigation objective. The technical assessment considers interference, the areas reached and remaining limits of the conclusions. It establishes which further investigation or work is needed for the planned groundworks.
Bring the report and plan appendices together
The report and plan attachments document the specialist works performed and their assessment. Worked areas, investigation depths, the relevant ground surface and limitations remain assigned. Reused older results and newly investigated areas are recorded distinctly. The agreed recipients receive the related documents together.
Use the result
Compare the report and its plan reference before subsequent works. The agreed recipients receive the complete results with their plan appendices and the outstanding specialist tasks for the next construction phase.
Documentation
Does the report still match the current construction project?
Findings and their scope
Check which interventions the report actually covers and which limitations it states. If additional foundations or utility lines are added, compare them with the previous investigation scope. A result for part of an area does not automatically apply to the whole site.
Project responsibilities
FONTANA-EOD’s documents describe the commissioned specialist service and its results. Official conditions and decisions remain separately identifiable. The technical documentation principles of the BFR Kampfmittelräumung may offer guidance outside their direct scope of application; their specific relevance depends on the project and applicable responsibilities.
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
A small extension is a specific construction task
The size of the extension alone does not answer an explosive ordnance question. The actual intervention and existing findings are decisive. A smaller project may lie outside previously investigated areas. Conversely, its description does not create a blanket suspicion; assessment is based on the documents.
Understand investigation reports and their limitationsTrack conditions and results separately
An official requirement describes what must be fulfilled or clarified for the project. A technical report documents a specific investigation. Both are retained for their respective purposes. Whether a condition has been met is clarified through the specific procedure, not inferred from the report title alone.
Understand the service scopeDesign and findings

Process and documentationQuestions from planning
Questions about alterations and groundworks in Solingen
Which project details does Solingen’s information sheet require?
These include the location of the building plot and a brief description of the project, particularly its groundworks. Use the current municipal guidance for the application. For technical coordination, supplementary groundworks outside the main structure should also be identifiable.
Does planning permission automatically mean work can start immediately?
Check the specific official decision. Solingen’s information sheet notes possible conditions precedent concerning clarification of the explosive ordnance situation. Clarify with the responsible authority which requirement applies to your project and which evidence is needed to fulfil it.
Does a small extension need separate consideration?
The actual groundworks and existing findings are decisive. Compare the scope of earlier evidence with the area of the new intervention. A small building size alone establishes neither a suspicion of explosive ordnance nor its exclusion.
Do utility lines outside the excavation belong in the investigation plan?
Yes, if they are part of the project. Groundworks for utility lines may lie outside the excavation initially described. Therefore record all proposed interventions so that the investigation commission and its result relate to the same working areas.
What should I do if I find a suspicious object in the ground?
Stop the affected works and keep your distance. Do not touch, move or further expose the object. Call the police on 110 and follow the authorities’ instructions; do not attempt to recover it yourself.
Why do ancillary works belong in the same intervention plan?
Because their groundworks may lie outside the main excavation. Show their position and depth separately and compare them with existing results.
What is needed when the ground level changes?
The existing and proposed conditions with a traceable elevation reference. This makes it possible to identify which ground areas the new depth figures actually describe.
Which documents and cost factors matter before commissioning?
The contractor needs the current plan, the associated complete reports and the relevant official information. Outstanding requirements and limitations remain identifiable. The effort also depends on usable existing documents, access and preparatory works, area size or the number and depth of investigation points, the suitable method, measurement conditions, and assessment and documentation. Any specialist services still needed are quoted specifically on this basis.
