Explosive ordnance surveys in Arnsberg: prepare groundworks
“New building” or “alteration” does not yet describe where or how deeply the ground will be disturbed. For a project in Arnsberg, the application, site plan and subsequent investigation design should fit together. FONTANA-EOD supports your technical preparation and helps identify which information is still missing for the planned works.
Show the parcel and intervention area together.
Describe excavations, utilities and other interventions.
Prepare consents and documents for the review.
Assess the construction project
Connect the authority application with the specific construction task
The City of Arnsberg and the Arnsberg District Government have different responsibilities in the procedure. For your project, we assign existing documents to the planned interventions. A permissible supplementary specialist service is described with its own scope and coordinated with the authority's procedural status.
Project site
Connect the site with the specific construction task
Distinguish the City of Arnsberg from the Arnsberg District Government
According to the municipal service information, the wartime aerial photograph assessment is requested from the Arnsberg District Government through the public order office. The city lists the site plan, property details, project description and owner's consent as required documents. For your project, this information is related to the specific construction design; further specialist work is coordinated with its own purpose and scope. Arnsberg is a town in the Hochsauerland district, within the Arnsberg administrative district, in North Rhine-Westphalia. Give the specific project address. For a project in another municipality, its local responsibility is clarified separately. The project location and proposed groundworks are considered together in further preparation.
Local context
The application goes through the town's public order office
Distinguish the municipal application from the state specialist task
The City of Arnsberg describes an application for wartime aerial photograph assessment through its public order office to the Arnsberg District Government. A site plan showing the cadastral section and parcel and a brief description of the construction measure are required. The city's document list also includes the property owner's declaration of consent. The explosive ordnance disposal service of the District Government then carries out the wartime aerial photograph assessment.
Add documents for technical preparation
Prepare the description so that the affected area is clear. The subsequent technical investigation also requires the specific groundworks and relevant depths. This detailed intervention planning is a different task from completing the municipal application. Information received must therefore reach the other designers together with its attachments and guidance.
The municipal address for the Niedereimer exhibition in 2023 recalls the air raid of 9 March 1945. For a present-day project, such historical information is considered with its spatial reference. Available knowledge of former buildings, reconstruction and later ground changes supplements preparation. The technical assessment concerns the parts of the property actually affected and the planned groundworks. Further work required is clarified using the specific records available and applicable requirements.
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 Arnsberg: wartime aerial photograph assessment for explosive ordnance detection · City of Arnsberg: ammunition and explosive ordnance finds · North Rhine-Westphalia KampfmittelVO: Section 3 in particular.
Planning and documentation: BFR KMR: principles of clearance planning · BFR KMR: geophysics · BFR KMR: documentation · North Rhine-Westphalia Ministry of the Interior: explosive legacy
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.
The City of Arnsberg's public order office is the local contact for the wartime aerial photograph assessment application and performs municipal hazard prevention tasks. The state explosive ordnance disposal service at the Arnsberg District Government carries out the official assessment and supports the competent bodies. The city and the District Government are identified with their different responsibilities. Authority requirements and the permissible scope of a private specialist service are coordinated for the specific project.
Investigation task
Which specialist task comes next?
Identify the outstanding technical question from the documents
Check which parts of the planned intervention are actually covered by the available information. An aerial photograph assessment and a technical investigation answer different questions. Further requirements are determined using these conclusions and the local design. Completing an administrative step does not establish additional technical knowledge.
Assess historical documentsClarify the service scope and responsibilities in advance
Describe the activity required with its area, task and achievable conclusion. Authority requirements and necessary state tasks are considered. Whether a supplementary service may be agreed privately is checked against the specific North Rhine-Westphalia conditions. The mere availability of a specialist company does not establish a permissible scope.
Compare investigation methodsProject types
Establish the same spatial reference for all participants
Describe the measure clearly
A project description such as new construction or renewal often leaves the actual interventions unclear. Add the area, depth and main work steps. The application details and technical design should describe the same project. Changes are incorporated visibly so that participants do not inadvertently work with different plan versions.
In addition to the main structure, identify the associated utility connections and working spaces. A deeper excavation may affect different ground volumes from a foundation previously considered. Depths refer to the relevant ground surface or elevation reference used. Where several plan versions exist, the one used for the enquiry is identified clearly. Structures added later are marked with their additional interventions for further coordination.
Specialist services and investigation tasks
Assign the owner's consent to the application
The city lists the owner's consent as part of the documents. Record which property and application it concerns. Further permissions required are clarified for the actual activity. A consent is not treated as a general investigation contract or a result of specialist work.
Where several parcels are affected, identify each area and its associated documents. If the enquiry concerns only part of a property, its location must remain clear. Access and the working areas actually needed are coordinated separately for the later investigation. The project file records the corresponding responses with their purposes. New execution or a changed scope is checked against them so that the owner, designers and appointed specialist company share the same spatial prerequisites.
Coordinate the sequence and tasksAttach existing reports in full
Older information and results help only if their limits are traceable. Also provide maps, attachments and any limitations. A brief summary cannot replace the respective scope of conclusions. Unresolved differences from the new design are expressly identified before the works affected.
Check which earlier measure an older document belongs to. A report for one construction section may leave out areas of a later connection or access route. Show today's working areas with their locations and depths. Missing attachments are requested from the issuer and identified as outstanding. The subsequent specialist design can then state precisely which existing conclusion fits and which addition is needed for the new intervention.
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
For the Arnsberg construction task, the authority application status and the technical conclusion still required are brought together. The application site plan and brief description are supplemented with the actual groundworks and their depths. This clarifies whether existing information must first be assessed, particular ground volumes investigated or previously assessed findings investigated further. The private specialist service receives its own agreed scope and suitable result documents. Submitting an application does not yet define that scope. Further preparation connects both tasks with the current plan version.
Define the specialist taskCoordinate preparatory work with the investigation
Before an investigation date, actual measurement access and available utility information are clarified. The owner's consent from the application procedure is considered according to its purpose; specific access conditions for fieldwork are agreed with the responsible participants. This includes coordination with other trades. Necessary preparatory works depend on the method and site. Surface changes or additional ground disturbance to create measurement access are technically prepared, not undertaken independently as incidental measurement preparation. Outstanding prerequisites remain visible before the appointment.
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
What belongs in the preparation?
01
Area on the site plan
Show which area the enquiry covers. If only part of the property is affected, it must be identifiable. Parcel details and the marking should designate the same area. A postal address alone does not reliably describe the intended investigation scope.
02
Explain the construction measure briefly
Describe the project with its planned groundworks. If new utilities are planned alongside an excavation, for example, they should not emerge only later during technical work. Design options still undecided may be identified as such.
03
Assign the consent correctly
The owner's consent identified by the city forms part of the prepared document set. Also clarify with the participants who will answer queries and pass on results. Consent to the application does not automatically replace coordination of access and practical investigation works.
04
Include existing information
If earlier information or reports exist, provide them in full. Maps and limitations belong with them. The new enquiry should show whether it concerns the same works, an extension or a different intervention. Incomplete documents are not treated as final evidence.
Project documents
Documents that establish the next step
Record procedural status and information status separately
A submitted application initially describes the progress of processing. The specialist information already available follows from the actual responses and results. Keep both details together with their date and reference. Subsequent project planning can then identify which decision remains outstanding and which conclusion is already usable.
Also assign responses to the area concerned. A completed procedure may, for example, concern an assessment while the recommended field investigation still needs to be commissioned. The associated tasks are passed on with their actual progress. A new appointment records which question is to be answered and which result document supplied. After receipt, it is checked which previous gap the specialist answer actually addresses.
Relate execution to the current position
The construction management team receives the relevant plans, authority information and specialist reports together. Their respective tasks and limits of conclusions remain intact. Earlier correspondence relating to another version is not reused without comparison. New interventions or changed depths are included in coordination before execution.
When several contractors are involved, each receives the documents and associated conditions for its own work area. Any area that becomes available later, or any change in the ground configuration, is communicated to the specialists involved. Earlier depth information is compared with the ground surface at that time and the current groundworks. Any further work still required remains specifically assigned. After clearance work has been carried out, the clearance record, including the scope, results and remaining limitations, is assigned to the part of the site actually treated and the corresponding site plan. The investigations and protective measures required are also clarified before exploratory openings or other advance groundworks, before the relevant work step begins.
Construction sequence
Coordinate investigation and construction sections
Agree the documents before submitting the municipal application
Bring together the site plan, property details, description of the proposed works and required consent. Include all known ordnance documents. Technical planning may require further details of the actual groundworks. Keep this information at the same plan revision, even where individual documents serve different purposes.
Determine the next steps after receiving a response
Read the statement together with its attachments and conditions. Compare its spatial scope with the current construction plans. This identifies the specialist and organisational tasks that remain outstanding. Any change to the works is reassessed before site management relies on the previous statement.
Method selection
Select methods according to the task and survey conditions
Historical records and aerial photographs
Historical aerial imagery analysis and other older documents help to place the basis for suspected ordnance in its spatial context. For the Arnsberg site covered by the application, the findings, the imagery examined and its limitations are carried forward into planning. The information obtainable from the images and any further available findings determine the state of historical knowledge. The absence of a visible finding is not a technical investigation of the ground as it is today. For excavations, utilities or other groundworks, it is checked whether the ground volume actually affected is covered by the analysis. Historical findings and any current measurement still required retain their different functions.
Understand aerial photograph assessmentMagnetometric survey
Magnetometric methods detect magnetic anomalies. For the groundworks described in the design, their suitability is assessed against the expected objects, ground conditions and required investigation area and volume. Fences, utilities and existing structures can influence interpretation. These conditions are assigned to the specific survey area. A signal is not identified as ordnance solely on the basis of its strength. The specialist commission connects measurement, assessment and, where necessary, further investigation with the information required for construction. Magnetometry measures the magnetic field passively. What matters is the magnetic effect of the object being sought; electrical conductivity alone does not make it detectable by this method.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations may be suitable for certain metallic target objects and site conditions. Technical planning records interfering installations, accessible survey areas and the information required for the proposed groundworks. The method is selected on specialist grounds rather than simply according to equipment availability. Recorded results include their location and the actual investigation conditions. Any further investigation required follows from the assessment and is linked to the current construction plan. Transient electromagnetic methods, or TDEM, evaluate the electromagnetic response of conductive objects over time. 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 on subsurface structures and reflections. Where the construction task is described only in general terms in the application, the information required for the actual groundworks is first specified. Ground conditions, moisture and installations affect interpretability. A reflection is not automatically ordnance; an unremarkable image does not confirm conditions at any arbitrary depth. Specialist interpretation and limitations are documented with the investigation commission. Before a radar report prepared for another purpose is used as ordnance evidence, its actual scope and intended findings are checked.
GPR and limitationsDeep-ground and downhole surveys
For deeper groundworks, it may be necessary to check whether investigation from the surface can provide the required information or whether another approach is needed. For technical preparation, the areas identified in the municipal application are supplemented with specific positions, depths and elevation references. Borehole layout and existing utilities then form part of planning; the preparation of suitable investigation access is also planned. A standard grid or a blanket depth figure does not replace this specialist task. Results remain tied to the areas actually investigated and the method used.
Prepare deep interventionsSurvey during construction
If a necessary advance investigation cannot be completed in full, it is assessed whether a professionally planned approach during construction is suitable. Specialist planning links investigation with interpretation and communication of findings for the specific groundworks proposed. Site management receives a description of when specialist work takes place, how new findings are handled and which areas remain unresolved. Visual observation of excavated material alone does not replace a necessary ordnance survey. An official response, together with its attachments and notes, is included in this coordination. The sequence is described for the actual construction task.
Agree the approach during constructionTechnical assessment
Turn the response into a specific investigation task
Read the findings and notes
The historical aerial photograph analysis must be read in its spatial context. Check what was investigated and which further steps the response identifies. The mere existence of a letter does not establish whether the groundworks now planned have been fully considered.
For a focused enquiry, identify the affected area and the relevant revision of the construction plan. If construction changes after the application, additional work areas and new depths are included in the coordination. Existing historical findings remain identifiable with their own scope. Any further research required is directed at the question still outstanding. The subsequent investigation objective is determined from this information and the actual conditions in the work area.
Choose the method to suit the need
Whether and how a technical survey is required follows from the findings and the planned groundworks. Existing buildings, utilities and other influences on measurement must also be considered. The investigation depth that can be achieved is professionally assessed on the basis of this information and the actual measurement conditions. Selection depends on the information sought, depth of groundworks, ground composition, existing utilities, interfering objects and actual measurability. Any suitable supplementary investigation or permissible supervision during construction is agreed with its specific scope.
Connect investigation and construction
The clearance plan or investigation planning should relate to the actual construction work. Agree the relevant depths and work areas before commissioning the investigation. If planning changes, it must be checked whether the specialist work already carried out is still sufficient. The results documentation records the work actually carried out.
Agree which reports and spatial plan attachments are required. The investigation carried out is documented with areas, points and depths, together with significant limitations. Inaccessible areas remain identifiable. Where work is carried out in sections, earlier results and new investigations are each assigned accordingly. For further groundworks, the documented scope is compared with the current plans. Outstanding follow-up measures receive a specific description so that the next commission can address the specialist work actually still required.
Next steps
Coordinate handovers and investigation within the project
From the client to the public order office
Submit the application with the documents required by the town. Keep a complete copy of the plan revision submitted. It helps establish later which area the response covers and whether the plans have since changed. State the project address and investigation question. Existing documents are checked for currency, area covered and gaps. Where historical information is missing, the necessary research is carried out. The official aerial imagery analysis required is undertaken by the responsible state service, and its findings are related to the current groundworks.
Pass the response to specialist planning
Pass on the findings, including maps and conditions. Individual sentences without their attachments can lose their spatial context. Only on this basis can specialist planning identify missing information and, where necessary, prepare further investigations. The suitable method is agreed according to the information sought, depth of groundworks, ground composition, utilities and measurement conditions. Permissible commissioning and any official coordination required are clarified before the work is carried out.
From specialist planning to investigation
Describe the areas to be investigated and the investigation objective in the commission. Clarify the conditions required for access. Construction equipment standing ready or an imminent construction start replaces neither this coordination nor a professional investigation.
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.
Pass documentation to site management
Hand over the findings in time for the affected work. Site management needs their spatial context and the remaining conditions. New or relocated groundworks are referred back for assessment before being treated as work already covered.
Documentation
A common plan revision prevents misunderstandings
Findings and their scope
The application, official response, investigation commission and results report may be produced at different times. Identify the date and plan revision in each case. This makes it possible to establish, for example, whether a utility route was added later. Completion of one part of the task establishes only what the associated documents actually substantiate.
Project responsibilities
The BFR Kampfmittelräumung describe specialist principles for planning and documentation; their direct scope is federal property. The applicable local requirements remain decisive for your project in Arnsberg. Private specialist work must be distinguished from the public order authority's responsibility for hazard prevention. FONTANA-EOD documents the permissible investigation commissioned and its actual scope. Official decisions are made by the competent authority.
Working approach
How FONTANA-EOD works
Document the agreed specialist service clearly
FONTANA-EOD carries out the agreed specialist technical task for the groundworks described in Arnsberg. Application documents and official responses are taken into account at their respective revision dates. Before work begins, accessible areas and the results required are agreed. If planning or local conditions change, the scope is reviewed accordingly before the affected work. The report documents the work actually carried out and its limitations. Site management can relate these findings to the planned construction work and identify any clarification still required. The private specialist service retains its stated purpose in relation to the official procedure.
Discuss the investigation taskThe task before the equipment
For method selection, a general project description in the application is translated into specific investigation questions. What matters is the ground area and volume affected, existing findings and conditions on site. Specialist planning explains how the selected method can provide the information required. Available equipment or the approach used on a similar neighbouring construction site is not sufficient as the sole basis. The selection and agreed results required are linked to the current construction plans.
Keep limitations visible
Inaccessible survey areas and areas with limited interpretability are identified by location and the reason for the limitation. Site management can assign the relevant activities and any further work required to them. A general description of the application area is supplemented with the parts actually investigated and the tasks still outstanding. Planning and construction teams agree when a suitable investigation will become possible. The documentation continues to show which ground area and volume the findings cover and where a decision still needs to be prepared.
Clarify changes before intervening in the ground
If additional areas, greater depths or other construction methods are proposed, the new plans are compared with existing findings before the affected work. Specialist planning is informed of the identifiable change from the previous task. Its response and any additions required are passed to site management with their scope clearly assigned. An unchanged application title or the same property address does not replace this specialist comparison. The technical work is related to the actual current construction plans.
Hand over the report and plan together
At handover, the official response, including its attachments and notes, and the technical results reports with their associated plans are passed on in full. Their respective purposes and revision status remain identifiable. A short overview can point to the findings important for the next activity and the areas still outstanding. The specialist findings continue to apply within the documented investigation scope. Even after a change of site management or contractors, this makes it possible to establish which evidence actually covers the planned groundworks and what further clarification is still needed.
Understand the results
Use technical statements for the next decision
The same place name does not mean the same task
The town administration and district government are identified by their respective roles in the procedure. This distinguishes the responsible point of contact from specialist support. A private commission also receives a clear description of services. This allocation helps with enquiries and prevents a document from being assigned to the wrong stage of work.
Understand investigation reports and their limitationsComplete documents allow reliable allocation
The spatial reference must match the description of the proposed work. Attachments and plan revisions are therefore passed on together. If essential information is missing, the resulting question remains unresolved. An amended document is identified by date and made available to those involved for further coordination.
Understand the service scopeDesign and findings

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 documentationQuestions from planning
Questions about preparing a project in Arnsberg
Should I contact the town or the district government directly?
According to the town's service description, the application to the district government is submitted through the public order office of the town of Arnsberg. The district government carries out the wartime aerial imagery analysis. Use the information provided by the town for the local application.
Which documents does the town of Arnsberg specify?
The documents listed are the application, a site plan showing the cadastral section and plot, a short description of the construction works and the property owner's declaration of consent. For subsequent specialist investigation planning, the specific groundworks and their relevant depths are also required.
Does aerial imagery analysis already constitute a technical ordnance survey?
No. Analysis of historical imagery and measurement in the field are different investigations. The further steps required depend on the findings, the official response and the proposed work. The documents must distinguish these steps.
What should I do if the plans change after the application?
Document the change and compare it with the area covered by the application or investigation. Before construction, clarify whether the existing response and investigation still cover the new groundworks. A change in depth or location may require renewed specialist coordination.
Who should I notify about a suspicious find?
Stop the affected work, keep your distance and do not touch or move the object. Notify the police immediately by calling 110 and keep other people away. The town of Arnsberg advises that ordnance finds must be reported promptly to the police or public order office.
What does a submitted application establish about the investigation status?
It initially represents a procedural step. Specialist findings arise from the responses actually available and the investigations carried out, each with its own scope.
Why is technical information needed in addition to the application?
Specialist planning requires the actual groundworks, depths and local conditions to be understandable. Each of the different documents serves its own purpose.
How do changes to the plans affect scope and costs?
The changed areas are clearly shown and compared with the existing findings. Any coordination still required takes place before the affected work. The effort depends on usable previous documents, access and preparatory work required, the area or the number and depth of investigation points, a suitable method and measurement conditions, and interpretation and documentation. Any specialist services still required are offered on the basis of the outstanding task and their permissible scope.
Project enquiry
Prepare the first technical discussion
Send a common plan revision
Clearly relate property details, the site plan, project description and planned depths to each other. Also describe ancillary work for utilities, access routes or additional excavations, including its location and depth. Identify the work areas needed first and the parts that will become accessible later. Communicate known existing utilities and other restrictions. For preparatory groundworks, clarify the investigations and protective measures required in each case. The enquiry connects this information with the specific investigation question still outstanding and the findings already available.
State the stage of the procedure
Include existing responses, reports and outstanding questions from the authorities. Identify the relevant revisions and any attachments still missing. For an extension, explain which area or depth is being added to the previous plans. The specialists involved can assess the existing findings against this change. For an area clearance or recovery task, the scope required and permissible commissioning are agreed with the competent authority. The agreed results documents are assigned to the area actually treated and passed to the agreed recipients.

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.
