Explosive ordnance surveying and disposal in Oldenburg
For project owners, geotechnical planners and construction companies in Oldenburg, FONTANA-EOD coordinates explosive ordnance assessment for drilling points, foundations and service trenches. Preliminary ground investigations are recorded as ground interventions in their own right, with their position, depth and method. Send the point list, site plan and existing explosive ordnance documents so that investigation needs can be clarified before the planned work.
Specify the position and depth of the investigation.
Include trenches and chambers.
Mark investigated points on the plan.
Assess the construction project
Also assess drilling points and small foundations
Individual boreholes, pad foundations and connection trenches are also ground interventions. For your project in Oldenburg, we compare their position and depth with existing explosive ordnance documents. This determines further investigation needs, which are coordinated with geotechnical planning and execution.
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, official conditions and reports are assigned to this area. Oldenburg is in Lower Saxony in the Weser-Ems administrative area. The City of Oldenburg is responsible for explosive ordnance hazard response within the city; information and existing reports are assigned to the specific property and ground intervention. For addresses in the city centre and central districts, Eversten, Donnerschwee, Osternburg, Bürgerfelde or Kreyenbrück, identify the available documents. For enquiries from Bad Zwischenahn, Wardenburg, Rastede, Hude, Westerstede or the Oldenburg district, the project location and respective competent municipality are clarified from the actual address.
Local context
Compare preliminary ground interventions by position and depth
Local starting point
Alongside construction plots, the City of Oldenburg’s guidance explicitly identifies civil engineering and pipeline projects, pad foundations and percussion core drilling. It also holds initial assessment information for certain areas and refers to the aerial photograph assessment provided by Lower Saxony’s explosive ordnance disposal service. The specific work area therefore remains decisive even for a preliminary measure.
The City of Oldenburg describes the Krusenbusch railway embankment site as a former marshalling yard whose track formation was built on placed sand. During the Second World War, the site was repeatedly targeted by Allied air raids. After the station was abandoned, tracks and parts of the ballast bed were removed. For projects around former railway installations, former transport areas, installations and fill are compared with later dismantling conditions. The original use and changes to the ground are considered together in the area-specific research.
Implications for construction planning
In a geotechnical site investigation, drilling points may be in different positions and extend deeper than the later external works. A service trench planned subsequently may in turn lie outside the area already investigated. Therefore check whether existing documents cover the position and depth of every intervention. A small work area is not safe merely because of its size. Existing documents for older housing, roads and service alignments, other infrastructure areas, and commercial, development and conversion sites are assigned to the work areas affected. Indications of former uses, relocated rubble, reconstruction or changes to the terrain are compared with the current design and intervention depths. For conversion sites, historical plans and aerial photographs are used where traces of former uses are now only partly identifiable on the ground.
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
Risk assessment, work areas and communication must suit the proposed activities. Ordnance specialist works are coordinated with the other construction activities. Operational organisation, traffic safety and other specialist technical inspections retain their own responsible parties. Joint coordination brings the information together without equating the different tasks.
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.
Local procedures: City of Oldenburg: explosive ordnance – guidance for construction projects.
Planning and documentation: BFR KMR: principles of clearance planning · BFR KMR: geophysics · BFR KMR: documentation · LGLN: explosive ordnance contamination on sites – who does what? · DGUV: explosive ordnance clearance FAQ
The BFR KMR guidelines are used as technical guidance; the applicable local requirements and responsibilities must be clarified separately. Their defined remit concerns federal projects; their application to other projects is clarified for the specific 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. § 7 SprengG concerns the commercial permit for activities requiring authorisation, and § 20 SprengG the certificate of competence of responsible persons. Under § 1b SprengG, searching for munitions that have been found also counts as handling.
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.
As the municipality, the City of Oldenburg is responsible for local hazard response. It holds initial assessment information for certain areas and refers aerial photograph assessments to Lower Saxony’s explosive ordnance disposal service. The state KBD supports the municipality in hazard investigation, recovery and disposal. Commercial specialist companies carry out commissioned technical investigations. Contacts, official conditions and reporting channels are agreed for the specific drilling points, foundations or service sections.
Investigation task
Which specialist task comes next?
First assess the existing findings
Aerial photograph analyses, official correspondence and earlier technical reports are related to the current project. What matters is which question each document answers and which spatial area it covers. Analysis of historical imagery must be distinguished from technical investigation of the present ground. If findings are missing or do not match the planned construction task, the further investigation needed is agreed with the specialists.
Assess historical documentsRelate the investigation to the area and depth
For the technical investigation, a suitable method is selected according to the objective, depth, ground and interference. A standard device alone does not define an appropriate service. The agreed scope identifies accessible areas and required results documentation. Even for a partial investigation, it must remain clear which area is actually investigated and which questions still require clarification afterwards.
Compare investigation methodsProject types
Describe small and deep interventions in Oldenburg precisely
Pad foundations and individual ground investigation points
A small above-ground extent says little about intervention depth. For a pad foundation, percussion core borehole or individual chamber, therefore specify the position, depth and construction method. Existing findings must relate to that precise area. An investigation of neighbouring land is initially only an additional document. A few drilling points do not establish a general conclusion for the entire property.
Each individual point receives an identifier used in the site plan and associated documents. The point list contains its proposed position, elevation reference and planned intervention depth. For a foundation, the ground volumes actually affected are also shown. If additional groundworks are planned for the equipment, identify these too. If a point moves as planning progresses, the original and new positions remain distinguishable. The specialist company checks the changed task against the existing results. The later report identifies the investigations carried out so that they can be unambiguously assigned to the work actually planned.
Understand downhole surveys
Pipeline construction with chambers and transitions
For a service project, the described working volume includes not only the alignment but also actual trench widths, chambers, shoring works and connections. Differences between sections remain visible. If a connection is relocated later, the change is compared with the previous investigation scope. The service length alone describes neither the task nor the evidence needed sufficiently.
The construction design shows where a continuous trench transitions into a chamber or connection pit. A cross-section can explain the planned widths, depths and additional working space there. If results from an earlier service section are used, their spatial boundaries are compared with this drawing. For changed connection positions, the affected plan sections are provided in their current version. Transitions to neighbouring sections also remain visible in the task description. The results handover links the area covered to its plan identifier and identifies tasks still outstanding. Site management thus receives the information needed for each trench or chamber section.
Specialist services and investigation tasksGeotechnical investigation before design development
Ground investigations are often needed before a foundation design is finalised. The investigation points themselves must be recorded as ground interventions. Geotechnical reports, service information and explosive ordnance documents answer different questions and are brought together. If an obstruction requires a point to be moved, the alternative position must be agreed with specialists before drilling; the original identifier is insufficient.
While the building design remains unresolved, the ground investigations initially needed are described as specific individual tasks. The design identifies which positions and depths are defined and which remain assumptions. An alternative position receives a traceable reference to the original investigation point; the reason for the change and specialist coordination remain documented. The results documentation then shows where work actually took place. Once the foundation design is developed further, its ground volume is compared with the existing explosive ordnance documents. Additional working areas, different depths and further investigation points are identified specifically. The geotechnical planners receive the relevant documents with the respective current plan version.
Understand downhole surveysPreparation
Prepare the scope and commission together
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
A reliable process distinguishes work already technically clarified from prerequisites still unresolved. If an area will only be partly accessible, this must be taken into account when commissioning the work. Handover and assessment of results also need time in the construction programme. Specific coordination connects the described scope with access, records, execution conditions and the date by which a decision is needed.
Discuss the scope and scheduleTasks at the site
Describe small work areas precisely
01
Ground investigations before new construction
Provide the proposed starting points and planned investigation depths together with the site plan. Possible point relocations should also be discussed beforehand. A result for a specific starting point is not applied without checking to a different position merely because both belong to the same construction plot.
02
Service trench with connection pits
Record the entire planned ground intervention, including chambers, connection points and necessary widening. The planned service line alone does not fully represent these working volumes. Existing utility services are relevant to construction planning but do not establish whether the adjoining ground has already been investigated for explosive ordnance.
03
Pad foundations and small structures
If a sign, technical installation or canopy is to be built, specify the foundation’s dimensions and depth. The visible size of the finished structure is insufficient for this planning. Also record additional earthworks for cables or drainage.
04
Work added later
If an additional borehole, infiltration system or subsidiary service is planned, check its relationship to the existing report. Record the new position and depth before agreeing execution. This enables targeted clarification of whether the change is already covered or requires supplementary investigation.
Project documents
Documents that establish the next step
Provide the point list and site plan together
A point list contains the planned positions, depths and methods. The site plan shows their relationship to the property and known installations. If the design changes, the list and plan are updated together. Alternative points or additional ground investigations are thus clearly identifiable before the next work stage.
Distinguish initial assessment from a specialist report
An initial local assessment can structure further clarification needs. An aerial photograph assessment and a technical investigation report each have their own scope. Send the complete available documents. Which conclusion already supports the specific intervention is determined from its contents and spatial reference.
Construction sequence
Coordinate investigation and construction sections
Preparatory investigation and initial ground works
The sequence is planned around the ground works actually proposed. Drilling, service diversions or temporary foundations may already be planned before the main excavation. For each affected area, it is clarified what must be established beforehand and which records are available. Construction plans already submitted may need additional construction details later. These additions are submitted for specialist assessment before the work concerned begins.
Further construction phases and changed plans
At the transition to the next construction phase, it is checked which results still apply. The location, depth and limitations described in the report are decisive. Additional working areas or changed methods are explicitly included. An interim release of an area for operational use and the technical findings of an investigation report are different matters. Site management receives the clarified status together with the associated plans and outstanding next steps.
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 is not an interchangeable substitute for a necessary survey. 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
What geotechnical reports, utility detection and surveying establish
Assess existing indications for the intervention
The historical aerial photograph analysis, earlier explosive ordnance reports and any available city information are compared with the planned work areas. Where several individual points are involved, unambiguous identifiers help. Using the associated documents, check which drilling positions the information about the property actually covers.
For this comparison, the existing information and its spatial reference are assigned to each planned point. This includes the respective map, its explanations and associated report appendices. Historical indications and technical investigations actually carried out are identified separately. If a conclusion cannot be assigned unambiguously to the proposed point using the documents, the unresolved question is sent to the relevant specialist body with the point’s plan identifier. The response remains available with the original documents. If the point position changes, this assignment is reviewed again so that further planning uses the current findings for the area concerned.
Select the surveying method
A deep-ground survey or another method must suit the investigation objective; the planned drilling depth alone is insufficient for selecting it. The investigation objective, ground conditions, installations and other interference must be considered by specialists. The result must show the area it relates to and the limitations of its conclusions.
The investigation commission describes the volume of ground to be assessed for the planned foundation, ground investigation point or other intervention. The specialist company explains which approach can address this objective under the actual conditions. Necessary position, depth and working space information is clarified before execution. The report links the method used with the positions actually investigated and the scope achieved. Limitations are assigned to the respective area. For subsequent planning, this keeps clear which results are available for the proposed intervention and where an additional specialist task needs describing.
A geotechnical report does not replace explosive ordnance assessment
A geotechnical report addresses different questions from explosive ordnance surveying. Utility detection or a contamination investigation likewise does not replace the explosive ordnance evidence needed. Before commissioning, clarify the sequence in which these investigations must take place and which results each subsequent investigation needs. Even on the same area, they remain different specialist tasks.
Where several specialist companies are involved, record for each ground investigation point the task to be carried out and documents needed. The responsible planners coordinate timing dependencies according to the planned interventions. Investigation results are handed over to subsequent participants with point identifiers, location and date. A changed drilling point or different planned depth is considered in this coordination before the affected work begins. The project overview links the investigation status achieved with the next work stage; the complete specialist reports remain available alongside it. For enquiries, the responsible specialist company can therefore address the precise point and its documented scope.
Next steps
Information needed for investigation planning
Mark points and alignments
Identify boreholes, foundations, trenches and additional working space on the plan.
Add depths
For each task, specify the planned intervention and relevant elevation reference.
Compare documents
Relate existing indications and results to these areas and record unresolved questions. For historical questions still unresolved, further land-use records are researched and suitable wartime aerial photographs assessed, where available. The resulting indications and assessment limitations are assigned to the planned points and alignments.
Coordinate specialist work
Agree the necessary explosive ordnance assessment before the exploratory or construction work dependent on it. Method selection depends on the findings needed, intervention depth, ground conditions, existing services, sources of interference and accessibility. Suitability and required preliminary work are explained for each point and alignment.
Investigate the agreed area
The specialist contractor carries out the commissioned investigation. Survey grids, necessary borehole locations and access for investigation are coordinated with the area, level reference, ground works depth and local conditions. Survey data and findings are spatially referenced; inaccessible sections and interference are recorded.
Assess findings and agree further work
The results are compared with the construction task. Anomalies, assessed findings and unresolved areas are identified separately. For confirmed explosive ordnance, recovery and further handling are agreed with the responsible bodies in accordance with the division of responsibilities in Lower Saxony.
Assign results documentation to the points
The report and its plans identify the points, areas and depths actually investigated. Survey conditions, limitations and outstanding tasks remain identifiable for the next investigation or construction activity. Where applicable, a clearance record relates the location, depth, findings and result of recovery work carried out.
Documentation
Locate investigation results in the construction plan
Findings and their scope
A report should identify the points or areas investigated so that they can be located in the construction plan. If starting points change or additional trenches are needed, it must remain clear which conclusions still apply. Therefore keep plans and explanations together. A brief notice without these appendices does not reliably show where investigations took place or their scope.
Project responsibilities
For official questions within the city, Oldenburg refers to its competent authorities. Municipal hazard response and the state explosive ordnance disposal service’s tasks remain separate from a privately commissioned investigation. FONTANA-EOD documents the commissioned explosive ordnance investigation. Official decisions are made by the competent authorities; other hazards are assessed by the respective responsible specialists.
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
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.

Specialist 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 boreholes and smaller earthworks in Oldenburg
Must percussion core drilling be considered in explosive ordnance assessment?
Yes, it must be described as a planned ground intervention. The City of Oldenburg explicitly mentions percussion core drilling in its guidance. The investigations required before a specific borehole must be clarified according to its position, depth and existing findings.
Does investigation of an excavation cover the service connection to the building?
Only if the documented result covers the connection’s required working area and intervention depth. If the trench lies outside it or deeper connection pits are added, this must be compared separately. Belonging to the same house is insufficient evidence.
Can an investigated drilling point be relocated at short notice?
Before drilling, check with the specialists involved whether the new position remains covered by the investigation result. Spatially limited evidence does not automatically apply to a relocated point. Update the point identifier and site plan.
Does a geotechnical report without adverse findings establish freedom from explosive ordnance?
No. A geotechnical report or contaminant-related result each answers different questions. Check whether an explosive ordnance investigation was actually carried out and documented for the planned area and depth.
What should I do if an item resembling munitions 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.
What information is needed for an enquiry concerning several drilling points?
Send an unambiguous point list identifying position, planned depth and proposed ground investigation method, together with the associated site plan. Identify alternative positions and points still subject to change. Existing investigation reports are assigned to these positions so that unresolved areas are identified before execution.
Are small foundations always unproblematic?
Their small visible size does not establish this. The specific location, existing findings and actual ground intervention are decisive. The construction method and depth also form part of the description. Investigation needs are assessed against these.
Which factors determine the investigation scope and costs?
The number and position of drilling points, intervention depths, available documents, ground conditions, metal interference and access determine the investigation task. Necessary preparation, interpretation, assessment of findings and documentation must also be considered. The point list and site plan are considered together; alternative positions or additional working space are identified when agreeing the quotation. Unresolved quantities and access remain assigned to the tasks concerned.
Project enquiry
Discuss drilling points and planned depths with us
Plan revision and decision deadline
State whether the enquiry concerns early planning, preparation for tendering or ground works about to begin. The date by which technical findings are needed helps coordination. Outstanding information is explicitly identified rather than replaced with assumed values. Specify the earliest ground works, construction time windows, maximum ground works depths and investigations already commissioned.
Assign records to their locations
Send a site plan and available reports with their associated appendices. For several construction phases, identify which document belongs to which area. Photographs supplement descriptions of access and existing structures; they do not replace information about underground structures or planned depths. Include official correspondence, conditions, service plans and ground investigation records or records of existing structures. Identify contacts and areas that are not yet accessible.

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.
