Explosive ordnance surveys in Delmenhorst
For explosive ordnance assessment before construction projects in Delmenhorst, FONTANA-EOD compares existing reports with present construction areas and ground works depths. Project owners, planners and site management receive a coordinated basis for necessary supplementary specialist work. Send a site plan and complete earlier reports, identifying changed property boundaries, additional construction areas and deeper structural elements.
Compare previously investigated areas with the construction plan.
Mark additional areas and deeper structural elements.
Document remaining gaps in the report too.
Assess the construction project
Compare investigation areas with the new construction plans
New land parcel boundaries or a shared address do not change the scope of an existing explosive ordnance report. For your project in Delmenhorst, we assign earlier results to the areas and depths investigated. Additional construction areas, connecting routes and deeper ground works are assessed separately before work begins.
Project site
Connect the site with the specific construction task
Site and existing requirements
Specify the actual project location with a site plan and the affected land parcels. Existing information, conditions and reports are assigned to this area. Delmenhorst is an independent city in Lower Saxony and belongs to the Weser-Ems administrative area. The city is involved in local explosive ordnance hazard prevention; the state explosive ordnance disposal service supports municipalities within its remit. Identify the version of the records and the body responsible for the project location for each site plan.
Local context
What earlier reports establish for the new construction plans
Local starting point
Site development may involve earlier analyses, partial investigations and new construction plans alongside one another. Reports must be assigned to the areas actually investigated, even if land parcels have since been merged or share an address. It must be checked which area a report actually addresses, which records underpin it and what it can establish for the proposed earthworks.
An air raid struck Delmenhorst on 8 October 1943. When assessing former uses, available damage records and historical aerial photographs are related to the present construction area. Earlier investigation results are included in the comparison within their own area and depth limits.
Implications for construction planning
The explanatory statement for development plan 374, “Straßenverlegung Am Wollepark”, documents an aerial photograph analysis requested from the LGLN in 2022. According to that analysis, no explosive ordnance contamination was suspected in the area described. At the same time, the document records that no survey or clearance had taken place. Vegetation and shadows restricted the visibility of the ground in parts of the aerial photographs. These details concern the status of this plan area at the time. With older records, therefore, check the basis of the result: aerial photograph analysis or technical investigation. Whether this means further investigation is needed for your project is clarified from the area covered, planned ground works and applicable requirements.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For the commissioned activities, the applicable technical requirements and questions of permits, competence and responsibility are clarified. The services actually planned are decisive. Required permits and certificates of competence are assigned to the activities described and the responsible persons.
Link occupational safety to the construction sequence
The risk assessment, work areas and communication arrangements must suit the planned activities. Specialist explosive ordnance work is coordinated with the other construction activities. Site organisation, traffic safety and other technical assessments retain their own responsible parties. Joint coordination assigns the relevant specialist work and responsibilities to the affected construction sections.
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.
The explanatory statement for development plan 374, Section 9 “Explosive ordnance” records an aerial photograph assessment of a specifically defined area. Other sites are considered separately according to their respective areas and ground works. The LGLN describes wartime aerial photograph analysis for hazard investigation and explains who performs which explosive ordnance assessment tasks. The clearance site notification and submission of work results are coordinated with the responsible bodies and commissioned specialist contractor. Historical information on the air raid is provided by the historical information and memorial panel on the air raid of 8 October 1943.
The principles of clearance planning, the geophysical investigation conditions and the BFR KMR documentation requirements help coordinate the objective, methods and results documentation. The spatial reference remains traceable for each section covered.
The defined remit of the BFR KMR guidelines concerns federal projects. Their technical principles are compared with the locally applicable requirements and responsibilities for the project.
For work in Germany, the permit, certificate of competence 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 covers preventive investigation and clearance of conventional explosive ordnance and defines its scope. Its explanations concerning DGUV Rule 113-003 relate to specific activities involving explosives; they are not applied indiscriminately to every investigation for construction. Section 7 of the Explosives Act concerns the commercial permit for activities requiring a permit, while Section 20 concerns the certificate of competence held by responsible persons. Under Section 1b, the Act also covers searching for found munitions.
Working together
Distinguish the tasks of client, designers and specialist contractor
Client and operator
The client describes the project and provides the available project records. The operator adds requirements for use, access and timing. A coordinating contact brings the parties together; individual tasks remain assigned to the named parties. Before commissioning, it is clearly recorded what information is missing, who will obtain it and what decision the result is intended to prepare.
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 contractor performs the agreed investigation and documentation work. Official requirements and decisions are clarified with the respective responsible bodies. The records needed for a specific procedure depend on the location and project. The technical report documents the specialist work carried out and its area, depth and limits of conclusions. The responsible bodies make official decisions concerning subsequent groundworks.
Official questions within the city are clarified with the City of Delmenhorst. In Lower Saxony, the state explosive ordnance disposal service supports municipalities within its remit. Conditions, contacts, reporting channels and handover of assessed findings are agreed for the project. The technical brief identifies the agreed specialist investigations with their area and depth limits.
Investigation task
Which specialist task comes next?
Distinguish aerial photograph analysis from technical investigation
An earlier file may contain a historical analysis, a technical investigation or both. The basis of its findings is therefore checked first. Comparison with the new plans includes the area considered, identifiable limitations and recommendations. A letter’s heading or a summary results line alone is insufficient.
Assess historical documentsDescribe additional ground works as a separate scope
Outstanding sections and depths are identified from the comparison. The further commission identifies these areas and the technical findings needed. Selection of suitable methods considers the existing structures and access in each area. Existing results are used where they fit the task; uninvestigated gaps are not silently treated as covered.
Compare investigation methodsProject types
Consider construction areas and connections together
Development of a subdivided site
After subdivision, several project owners may use records originally prepared for a larger area. What matters is the area the investigation actually covered at the time. Assignment is based on associated plans and identifiable spatial references. New land parcel identifiers are documented additionally. Each client can then understand which results apply to their ground works and which questions remain unresolved. Compile all available reports, even if they name different owners or earlier land parcel numbers. The latest report may concern a different section from an older one. A list with dates, titles, appendices and the assessment or investigation area shown makes assignment verifiable. Missing maps are requested from the original client or responsible body. A new ownership or address assignment does not itself bring the separate investigation scopes together technically.
Document findings and their limitations
Utilities between previously investigated sections
A new utility corridor may lie outside both investigated construction areas even though it connects them directly. Connection pits, chambers and additional working areas must also be included with their depths. The route is compared with the existing investigation maps. The results for adjoining areas provide a planning basis but do not replace evidence for an intervening area not covered. Also consider small connection pits, drainage pipes and individual borehole positions. Even a short ground intervention may lie outside the old investigation boundary or extend deeper. The locations and depths of such additions are checked with the specialist planners before the work step concerned.
Specialist services and investigation tasks
A new use with deeper foundations
A change of use may require different foundations, a basement or deeper drainage. The documented investigation is therefore compared not only with the building outline but also with these new depths. An earlier report may still contain usable findings. The additional investigation needed for ground works beyond it is determined by specialists and agreed before the work concerned. The comparison includes the ground or level reference used at the time and the present planned levels. If fill, excavation or altered structures change the reference, the respective limits are clearly compared. This identifies the new question that supplementary investigation is intended to answer.
Provide specialist supervision of excavationPreparation
Prepare the scope and commission together
Establish what needs to be known before commissioning the work
The commission first needs to clarify which decision is to be prepared. Does it concern an initial assessment of existing records, investigation of a specific area or further work on a finding already assessed? These tasks need different information. A general desire for safety does not yet describe an investigation scope that can be carried out. The enquiry therefore identifies the ground works, location, depth and available findings. Suitable specialist work and required results documentation are agreed on that basis. Where area clearance is needed, the clearance objective, area covered and relevant execution conditions are described in the clearance plan. The results documentation relates to this agreed task.
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
A reliable workflow distinguishes work already clarified technically from prerequisites still outstanding. If an area will be only partly accessible, this must be taken into account when commissioning. Handover and assessment of results also need time in the construction programme. Specific coordination relates the described scope to access, records, execution conditions and the date by which a decision is needed. For comparable tendering, previously investigated areas and new tasks are marked on the same plan. Identify additional connection areas, required depths and expected results documentation. The service description identifies access, known limitations and, where applicable, separate construction phases wherever these affect execution and the work involved.
Discuss the scope and scheduleTasks at the site
Assess buildings, connections and additional areas
01
Construction areas and boundary strips
Mark buildings, working areas and other ground works on a shared site plan. If an excavation extends beyond the previously investigated area, the additional strip must be assessed separately. The construction property boundary and investigation boundary need not coincide.
02
Access roads and utilities between construction areas
If individual sections are linked by an access road or new utilities, these connections must also be considered. Two existing reports on neighbouring construction areas do not themselves establish the investigation status of the corridor between them. Also specify the locations and depths of connections.
03
Basements and deeper foundations
An old report may relate to different ground works or a different level reference. Planned depths must therefore be compared for new basements, foundations or drainage systems. Even if the construction area has already been investigated, the documented depth must match the new ground works.
04
Separate construction phases
For phased development, it should remain clear for each phase which records exist and which tasks remain unresolved. Add later changes to utilities, access roads or site areas to the respective construction phase. Before work begins, assess whether further investigations are required.
Project documents
Documents that establish the next step
Establish a clear assignment of earlier reports
Assign a title, date, associated plan and investigated area to each report. If land parcel numbers or plan identifiers have changed, establish the relationship. Incomplete records and missing appendices remain identifiable in the overview. Further assessment can then build on existing results and address the questions actually outstanding.
Show investigated areas on the current plan
Site management needs a traceable comparison of the investigation scope and proposed earthworks. Additional corridors, deeper ground works and inaccessible sections are each identifiable. Revised plan versions are passed on with dates. An overview plan helps orientation, while complete technical reports and their limitations retain their binding assignment. After clearance work, the clearance record with its scope and results is assigned to the area covered and corresponding plan version.
Construction sequence
Coordinate investigation and construction sections
Before phased site development
If several construction phases are developed in succession, their shared connections should already be identifiable during preparation. This includes access roads, utilities and temporary ground works. Each phase is compared with the existing results. Timely coordination prevents a connecting corridor from being identified as an outstanding investigation task only shortly before its construction. The specific sequence depends on the project and its technical prerequisites.
At handover to new site management
New responsible parties need complete reports, associated maps and the current plans. A list of construction phases already completed alone does not describe investigation boundaries. Outstanding areas, previous limitations and depths changed in the meantime are therefore also handed over. Before the next ground works, it is assessed whether the findings handed over cover the work actually proposed.
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 may be suitable for certain metallic target objects and site conditions. Suitability is justified for the particular task, rather than inferred from equipment availability alone. Interfering installations, accessible areas and the conclusion required must also be considered. Results are documented with their location and investigation conditions. Whether a supplementary method is needed follows from the technical assessment and remains a specific project decision. TDEM records time-dependent electromagnetic responses from electrically conductive objects.
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 investigation task affect interpretation. An anomaly is not automatically explosive ordnance, and an area without anomalies is not general evidence for arbitrary depths. The technical interpretation and limitations are documented with the commission. An investigation for other purposes is not adopted as explosive ordnance evidence without assessment. Highly conductive ground can limit its range.
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, it is assessed whether a technically planned approach during construction is suitable. This includes coordinated investigation, interpretation and communication of findings within the planned workflow. Visual observation during excavation alone does not meet the state of the art for preventive explosive ordnance clearance. Site management needs a clear description of when specialist work takes place, how new findings are handled and which areas remain unresolved. Where the method is suitable, each working layer is technically surveyed and assessed before controlled removal in layers. Visual checks supplement the survey. The process continues to the agreed excavation base and, where necessary, along walls or slopes; the stop signal, authority to issue instructions and reporting channels are agreed beforehand.
Agree the approach during constructionTechnical assessment
Which records and investigations are still needed?
Assessment area and associated plans
The aerial-photo analysis must be read in terms of its specific assessment area and findings. For an application, the LGLN requires, among other details, a clear marking of the area to be assessed. If only a summary without its associated plan is available, the complete document should first be obtained; neither a positive nor a negative result may be extended beyond its limits.
Survey conditions in each section
For a necessary technical investigation, buildings, paved surfaces, utilities and other interference in each section are relevant. The geophysical survey is selected according to the investigation objective and local conditions. A method suitable for an open neighbouring area cannot be applied to a built-over connection area without assessment.
Specialist contractor, municipality and KBD
According to the LGLN, commissioned commercial specialists carry out hazard investigations; official measures are the responsibility of municipalities. The state explosive ordnance disposal service’s tasks are separate. A clearance plan describes the investigation task and necessary coordination. Official responsibilities remain unchanged. Provide official correspondence with its full wording, date and associated plans. The area to which the information or decision applies and the tasks still to be addressed are recorded. Revised plans are passed to the specialist planners and contractors involved before the affected ground works.
Next steps
Compile reports for further planning
Clarify the initial enquiry and available records
Bring together complete reports with appendices, earlier official correspondence and the new plans. A list with dates, titles and associated areas makes report assessment easier. Incomplete copies and missing appendices are explicitly noted. The first discussion identifies the project and next decision needed. Assign existing explosive ordnance records and their appendices to the old and new land parcel identifiers. The client, planners and site management identify who will obtain missing records and who needs the assessed results for the next work.
Compare earlier investigation boundaries with the ground works
Compare the described investigation areas and planned ground works using the same spatial reference. Overlaps, additional areas and different depths should each be identifiable. Whether an older report remains usable must be assessed from its contents and the planned work. Also show connecting routes, connection pits and new working areas. An earlier investigation area may cross a new subdivision boundary or cover only part of the present project. The comparison distinguishes usable findings from further clarification needed for each ground intervention.
Supplement historical research and aerial photograph analysis
If the existing information is incomplete or historical questions remain unresolved, suitable additional records are researched and historical aerial photographs analysed for the area concerned. Earlier uses, identifiable indications of damage and existing investigations are spatially assigned. The scope of interpretation, photographic conditions and analysis limitations are recorded. The results help determine the further investigation tasks for the ground works planned today.
Define investigation methods and additional needs
The comparison shows which results can be used for the project and which questions remain unresolved. The type and scope of further investigations are then defined. Existing results are considered wherever they actually cover the planned ground works. Method selection takes account of the investigation objective, ground works depths, ground structure, existing structures, utilities and metal interference. Surface, geophysical or, where applicable, depth-related investigations are selected for the specific findings needed. Survey grids or borehole positions follow from this task and local conditions. Necessary preparatory work and access are agreed before work begins.
Carry out the survey and assess findings
The specialist contractor investigates the agreed areas or points using the agreed approach. With a suitable investigation during construction, technical specialist work and controlled construction progress are coordinated. Interpretability, interference and inaccessible areas are documented. Survey data and findings are assessed professionally; anomalous signals are related to the investigation objective and local conditions. Necessary further clarification and measures are identified with the areas affected.
Document results and limitations traceably
The report and associated plans identify the areas or points actually investigated, depth reference and method used. Results, survey conditions and limitations are recorded together. Outstanding sections or depths remain identifiable. Where clearance work was carried out, the clearance record documents the scope covered and result. The associated records are handed over with their plan version to the client and site management.
Pass on next-step decisions and plan changes
Specify who passes new plan versions to the specialist planners and contractors involved. A relocated connection or changed excavation can alter assessment needs. Such changes are assessed before the affected ground works and recorded in the documents. Before the next ground works, usable results, outstanding investigations and necessary coordination with the authorities are assigned to the construction phase concerned. For new or relocated structures, it is assessed whether the documented result covers their areas and depths. Agreed next steps and the parties responsible for them are recorded. Subsequent contractors receive the associated plans and technical limitations.
Documentation
Document investigated and unresolved areas
Findings and their scope
The documentation should identify the area investigated, its relationship to the plans, the method used and the limits of its findings. Investigated and outstanding sections must be clearly distinguishable on the overview plan. Associated appendices must remain together when passed to site management and subsequent planners. A survey report brings together the investigation task, results and limitations. A clearance record documents completed clearance work with its location, scope and result. Associated plans relate these details to the area actually covered.
Project responsibilities
In Lower Saxony, the required clearance site notification is submitted to the responsible trade supervisory authority; the state explosive ordnance disposal service receives a copy for information. After completion, the work results are submitted to the KBD. Required notifications, contacts and handovers of documents are defined with the commissioned specialist contractor before work begins. The technical report and official decisions retain their respective purposes.
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 findings are identified. They are shown separately in the report and overview plan. Planners and site management can then decide specifically which areas still need work and when a suitable investigation will become possible.
Clarify changes before intervening in the ground
A new location, additional depth or different construction methods are compared with the existing results. The current ground works and plan version remain decisive even if the project name is unchanged. Feedback is provided before the affected work so that an unresolved question can be incorporated into the workflow.
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
Read results together with their scope
A statement is understandable only with its investigation task. Check the area and depth described, methods used and restrictions. A report title or single result line is insufficient. For new work, these details are compared with the current plan to establish which knowledge remains usable and which question is unresolved.
Understand investigation reports and their limitationsUse project terminology unambiguously
Document review, surveying, construction-phase specialist work and recovery are different tasks. An enquiry need not identify the correct method in advance. An accurate description of the intervention and required decision is more useful. This establishes the appropriate technical scope and prevents a general term from meaning different things in design, procurement and execution.
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.
Understand aerial photograph assessmentSpecialist reports for site management
The findings, their locations and limitations are handed over together. This makes clear to those carrying out the work which area has been investigated and which task remains outstanding.

Process and documentationQuestions from planning
Questions about site development in Delmenhorst
Can a report still be used after a site is subdivided?
This must be checked against the report. The area investigated, documented conditions and planned ground works are decisive. A new land parcel number alone does not change the scope of the earlier investigation.
Is an assessment of an adjoining construction area sufficient?
It can provide relevant preliminary information but does not automatically cover your own ground works area. The assessment area, findings and limitations of the existing investigation must be compared. Any further clarification needed for areas not covered must be determined separately.
Does a development plan establish that a site is free of explosive ordnance?
A plan drawing or public notice alone is not investigation evidence. Existing technical reports and official requirements must be read together with the specific ground works. A planning designation does not establish a blanket finding about explosive ordnance in the ground. Before the planned ground works, agree the required investigation scope with the specialist contractor and official requirements with the City of Delmenhorst. The state explosive ordnance disposal service supports the municipality within its remit.
Must all sections be investigated in the same way?
No. The method and scope depend on the justified investigation objective and conditions in each area. Different access or interference may require differentiated planning. The choice must be technically justified and coordinated with the applicable requirements.
What should you do if a suspicious object is found?
If possible explosive ordnance is found, stop work at the location immediately. Do not touch, move or expose the object further. Leave the immediate area, keep your distance and keep others away without putting yourself at risk. In Germany, notify the police immediately on 110 and follow their instructions. Inform site management and the client; internal reporting must not delay the emergency call. An enquiry form for planned construction projects is not an emergency reporting channel.
Which documents are needed after land parcels are merged?
Earlier and current site plans and complete investigation reports with appendices are helpful. Establish the spatial relationship between earlier identifiers and present plans. A new shared land parcel number does not automatically make individual report findings applicable to the entire area.
Must existing investigations always be repeated?
No. First, it is assessed which reliable results already exist and which part of the current construction task they cover. Supplementary investigations depend on the remaining questions and applicable requirements. The outcome of this comparison must remain traceable for each area and depth.
What matters for obtaining comparable quotations?
Describe the planned ground works and provide all existing technical reports with their appendices. Identify outstanding areas and the handover of results required. Include access, construction phases and decision dates. Quotations can be compared meaningfully only if they relate to the same investigation scope and prerequisites. The work and therefore costs also depend on area, depth, survey conditions, necessary preparatory work and the investigation scope still outstanding.
Project enquiry
Enquire about site development in Delmenhorst
Mark changed land parcels and ground works
Send the current site plan with construction areas, connecting routes and proposed depths. Add earlier land parcel or plan identifiers if these are used in existing reports. Outstanding connection areas and plans still subject to change should be explicitly identifiable. If you are having a site in Delmenhorst assessed for suspected explosive ordnance contamination, existing indications are compared with the ground works actually proposed. Also mark ground works outside the new property boundary wherever these are planned for connections or temporary working areas.
Compile earlier reports and the decision date
Provide complete investigation reports with plans, appendices and official correspondence. Identify the next construction phase and the date by which technical findings are needed. Tell us who can obtain missing records and which parties should receive the agreed investigation scope. Add the level reference, utility information, ground investigation records or records of existing structures, and known survey obstacles. State which construction activities are to begin first and which sections remain inaccessible for the time being.

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.
