Explosive ordnance surveying in Ingolstadt
Former production or storage areas may need particular assessment before new ground works. FONTANA-EOD agrees with project owners, designers and site managers in Ingolstadt which explosive ordnance services are required by the history of use, existing investigations and planned ground disturbance. Send a location plan, records of existing structures and remediation or construction plans with depths so the specialist work needed can be clarified before the next ground works.
Trace previous activities.
Coordinate remediation and new construction.
Define the specific specialist commission.
Assess the construction project
Which documents help assess a former industrial site in Ingolstadt?
Plans of existing structures, information on earlier activities and complete investigation reports are helpful. Relate these documents to the present-day areas and add the proposed ground works. Contaminant investigation, geotechnical assessment and explosive ordnance assessment retain their respective tasks. For the next ground disturbance, clarify which findings apply and which specialist services are still needed.
Project site
Connect the site with the specific construction task
Treat INquartier as a specific planning example
The environmental report describes a particular earlier use and the relationship planned at that time between ground remediation and explosive ordnance services. Another property in Ingolstadt needs its own findings. Land-use planning, private investigation commissions and local hazard response retain their different tasks. Ingolstadt is an independent city in the Upper Bavaria administrative district. The Ingolstadt region also includes the districts of Eichstätt, Neuburg-Schrobenhausen and Pfaffenhofen an der Ilm. For a project in the surrounding area, the specific municipality determines local responsibility. State the address, cadastral plots and former works section names so planning documents can be assigned to the correct site. Further areas are listed in the regional overview; contacts and the specialist commission are clarified for the actual project location.
Local context
Armaments production, war damage and present-day ground works
Understand the historical use described for INquartier
The environmental report for Ingolstadt's INquartier dated 10 July 2023 identifies former weapons and ammunition production and an associated suspicion of explosive ordnance for that planning area. It forms part of the explanatory statement for land-use plan 115 F in the version for renewed public consultation dated 14 July 2023. The conclusion concerns this area; any other former commercial use does not establish the same findings.
The city's commemorative page Ingolstadt under National Socialism describes the significance of the garrison and armaments industry and identifies heavy bombing raids from 15 January 1945. The city archive's photograph collection documents, among other scenes, clearance of rubble at the destroyed Salzstadel and Augustinian monastery in 1945. For a present-day property, compare aerial photographs, building records and such local historical records with earlier structures and later ground changes. The results remain tied to the area and question actually documented.
Distinguish planned remediation from investigations carried out
The report also links the proposed ground remediation with supervision by an explosive ordnance specialist contractor. This describes the planning at that time, rather than evidence of completed clearance. For your property, what matters is which activities actually took place there and what the investigations now available establish. A general reference to a former factory does not replace these documents.
The 2023 planning statement describes the former Rieter and Bäumler site south of Römerstraße and east of Friedrich-Ebert-Straße. Its recorded historical structures include the water tower built in 1915 for the gun factory of the Royal Bavarian Main Laboratory. Such building information helps relate former works sections to present-day areas. The INquartier report remains a source for its planning area at that time. For another industrial site, assess its own documents, periods of use and ground disturbance boundaries; known gaps inform further research.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For the commissioned work, the applicable technical requirements, permits, competence and responsibilities are clarified. The actual scope of work is what matters. Tasks and interfaces are described for the project and checked against the required authorisations.
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 environmental report for INquartier dated 10 July 2023 sets out the earlier use and the relationship proposed at that time between ground remediation and explosive ordnance services. The city's public participation in land-use planning procedures shows the respective plan versions and consultation information.
The BFR KMR guidelines on clearance planning connect the investigation task with the subsequent process. The guidance on geophysics supports the choice of method, while the guidance on Documentation supports results handover. The Bavarian notice on explosive ordnance hazard response dated 13 August 2026 sets out responsibility, prevention and hazard response.
The BFR KMR are used as technical guidance; locally applicable requirements and responsibilities must be clarified separately.
Permits, competence and responsibility for the specific activity are considered 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 references to DGUV Rule 113-003 concern particular activities involving explosives; they are not applied indiscriminately to every construction-site investigation.
Working together
Roles and responsibilities at the location
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 carries out the agreed investigation and documentation work. Requirements and decisions of public authorities are addressed with the responsible bodies. The documents needed for a particular procedure depend on the location and project. The technical report describes the work carried out, including its documented area, depth and scope. Decisions reserved for public authorities are made by those authorities.
For Ingolstadt as an independent city, clarify municipal coordination within the city boundary. Under the Bavarian notice, the München disposal unit is responsible for Upper Bavaria except the district of Eichstätt, which falls within the Nürnberg disposal unit's area. For a surrounding-area project, the actual municipality therefore matters. Police, public safety authorities and the commissioned explosive ordnance disposal service carry out their respective tasks where specific hazards arise. Agree private research, investigation and documentation commissions with their own scope of services.
Investigation task
Which specialist task comes next?
Determine the investigation from the specific question
Only comparison of historical findings, existing reports and the construction design establishes the remaining need. Consider the actual measurement conditions too. Remaining structures may affect interpretation. The agreed method should answer the project's question and document its limits clearly.
Determine investigation methods from the outstanding questionDefine supervision services explicitly
If explosive ordnance services are to accompany earthworks, their suitability and prerequisites need specialist clarification. A general reference to supervision does not define the necessary scope of services. Planning sets out tasks, sequence and results handover. This does not establish that every excavation activity is permissible.
Compare investigation methodsProject types
Relate the history of use to the current earthworks
Trace historical information spatially
A former company address may cover a larger site than the current project. Assign production areas, storage areas and later changes of use on the plan where known. Identify unclear information. The assessment relies on available findings and states which question remains unresolved for the specific area.
A reliable property file includes the complete historical documents with maps and appendices. Mark the locations of production premises, storage, traffic areas or buildings later removed where the records establish these. Compare old property boundaries with current cadastral plots. An alteration may have affected different ground volumes from the disturbance now proposed. The specialist assessment therefore distinguishes known uses, documented ground works and areas still unresolved. If the underlying information is incomplete, determine the further research needed and relate it to the next investigation step.
Arrange specialist assessment of historical evidence
Plan the different specialist tasks together
Investigation points, remediation and new construction may affect the same ground volume at different times. Describe the upcoming works and conclusions needed for them. The specialist designers involved coordinate prerequisites and handovers. A commission for one investigation does not automatically include every further service.
A remediation plan may describe, for example, which ground material will be handled and the work steps proposed. Explosive ordnance planning determines the investigation needed and how findings will be addressed. Geotechnical and contaminant investigations provide their respective findings for the same ground disturbance. Agree in advance which conclusions are needed before drilling, removing a foundation or the next excavation. The specialists involved receive the current plans. Include changes to the remediation sequence or new ground disturbance areas in this comparison before construction.
Compare specialist services
Record the scope completed clearly
A results report shows which task was actually addressed and what limits apply. Proposed next steps remain distinguishable from completed work. Pass the complete documents on to the parties involved. For a later construction section, check whether existing results cover its specific ground disturbance.
For handover to the next trade, bring together the report, results plans and associated ground works plan. Areas investigated and limitations must be locatable on the plans. Identify areas not yet investigated or sections where measurement conditions limited assessment explicitly. If the project expands later, compare the additional ground volume with existing results. Usable earlier conclusions remain available; the new commission describes the remaining need. Keep the relevant investigation status traceable even if the site management team or contractor changes.
Document findings and their limitationsPreparation
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.
On a former factory site, remaining parts of buildings and filled structures may change access to individual ground volumes. Describe the current condition alongside the proposed demolition. Exploratory boreholes and investigation points for other reports also belong in preparation with their locations and depths. The parties agree which findings must be available before these ground works and how to combine necessary specialist work. In the tender, assign the documents to be provided, required preparatory services and expected results plans clearly. Quotations then relate to a defined scope.
Clarify preparatory work in the programmeAgree a clear scope and schedule
A realistic programme distinguishes technically resolved work from prerequisites that are still outstanding. If only part of a site will be accessible, the commission must take this into account. Handover and assessment of the results also need time in the construction programme. The schedule and effort are agreed once the scope, access and prerequisites are clear. This coordination brings together the specified scope, access, documents, site conditions and the date by which a decision is needed.
Discuss the scope and scheduleTasks at the site
Prepare ground remediation and explosive ordnance assessment together
01
Locate earlier uses
Collect available plans of existing structures and information on earlier buildings, production areas or storage areas, and known periods of use. A company name alone is too imprecise. What matters is which part of the present project overlaps a particular use. Later alterations, filling or changes to property boundaries may also matter for this allocation.
02
Distinguish the purposes of the reports
A contaminant report assesses different ground properties from an explosive ordnance investigation. Nevertheless, provide the documents together where they concern the same earthworks. This allows planned investigation points, remediation sections and necessary investigations to be coordinated. A contaminant result without adverse findings does not answer the explosive ordnance question.
03
Include preparatory ground works
The construction project also includes work before the new building itself: for example, removing remaining foundations, exploratory boreholes or new utility trenches. Add these ground works to the design with their locations and depths. Where explosive ordnance is suspected, plan the necessary clarification in good time before the affected works.
04
Review the commission when the design changes
If a remediation area expands or a foundation is designed deeper, the investigation need may change. Pass such changes to the specialists involved before construction. Use a previously agreed investigation only within its demonstrated scope. Missing conclusions for an additional area must remain clear.
Project documents
Documents that establish the next step
Relate earlier and present-day area names
Older plans may use building or works section names absent from the current location plan. Show known relationships and identify unresolved allocations. This relates specialist documents to the correct section. An assumption about location is not treated as a confirmed investigation boundary.
Coordinate the remediation sequence with investigation
If ground is to be replaced or a remaining structure removed, include this ground disturbance in the joint preparation. The necessary findings must be available before the affected work. Subsequent new construction may raise further questions. Describe each task with its ground volume and investigation status. If clearance work has been carried out, use its clearance record, including areas addressed, methods, findings and outstanding tasks, to compare the subsequent remediation and construction phases.
Construction sequence
Coordinate investigation and construction sections
Start with the available property file
Provide the existing documents, including maps and appendices. Add known changes to areas and buildings. The initial discussion identifies usable information and missing details. Then relate the commission to the conclusions actually needed for the proposed ground works.
Compare an additional construction area separately
If a further remediation section or connection is added during design, identify its location and depth clearly. Check existing results against it. Agree the additional need with the parties involved. A shared project name does not automatically extend an earlier investigation's scope.
Method selection
Select methods according to the task and survey conditions
Historical records and aerial photographs
Historical aerial photograph assessment and other old records help place the basis for suspicion in its spatial context. The available images, their evidential value and the limits of the area considered matter. The absence of an identifiable indication must be distinguished from a technically surveyed ground area. The assessment is considered together with the planned intervention and other available findings. It can support the choice of a survey, but is not a measurement of the present-day subsurface or confirmation for all future works.
Understand aerial photograph assessmentMagnetometric survey
Magnetometric methods detect magnetic anomalies. Whether they can address the specific survey task depends, among other things, on the expected objects, ground conditions, interference and required survey area. Fences, utilities or existing structures may affect interpretation. A measurement signal is therefore not described as ordnance solely because of its strength. Method, interpretation and any further investigation are planned as a connected specialist task.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations can be suitable for particular metallic targets and site conditions. Their suitability must be explained for the task, rather than inferred simply from the availability of equipment. Interfering installations, accessible areas and the findings required must also be considered. Results are documented with their location and survey conditions. The specialist assessment determines whether a supplementary method is needed; this remains a project-specific decision.
Understand electromagnetic surveyingGround-penetrating radar
Under suitable conditions, ground-penetrating radar can provide information about subsurface structures and reflections. Ground conditions, moisture, installations and the particular survey task affect interpretability. An anomaly is not automatically ordnance, and an area with no apparent anomalies is not general evidence for arbitrary depths. The specialist interpretation and its limits are documented with the instruction. A survey for another purpose is not adopted without checking as ordnance evidence.
GPR and limitationsDeep-ground and downhole surveys
For deeper groundworks, it may be necessary to establish whether a surface investigation can provide the required findings or another approach is needed. Preparation includes the location, depth, borehole layout and existing services. Creating access for the investigation must also be properly planned by specialists. A general depth figure or standard grid cannot replace that work. Findings remain limited to the areas actually investigated and the method used.
Prepare deep interventionsSurvey during construction
If a necessary preliminary investigation cannot be completed, the specialists assess whether a planned approach during construction is suitable. This includes coordinated investigation, interpretation and communication of findings within the intended work sequence. Visual observation of excavated material is not an interchangeable substitute for a necessary survey. Site management needs a clear description of when specialist work will take place, how new findings will be handled and which areas remain unresolved.
Agree the approach during constructionTechnical assessment
Which investigation answers the outstanding question?
Assess historical indications
A Historical aerial photograph analysis may help assess indications of suspicion together with other available records. Not every earlier activity is visible in aerial photographs. Identify the available source material and its limits in the results. Include existing reports in this comparison so usable findings are not overlooked.
The Historical aerial photograph analysis is compared with the documented use and other sources for the same area. Consider available images, image coverage and recognisable changes. An earlier investigation also needs its location and elevation reference to be used for the current design. Identify missing appendices or unclear plan versions. The next commission clarifies which information will be added and which technical investigation builds on these findings. The site management team is informed which preparatory ground works depend on them.
Consider measurement conditions on site
For any necessary Surveying, remaining structures, utilities and metal installations are among the factors affecting measurement conditions. Match the appropriate method to the investigation objective. Interpretation must distinguish areas that could be assessed from those with limitations. A measurement signal alone is not a confirmed explosive ordnance find.
Remaining foundations, steel reinforcement, old utilities and metal-bearing fill may interfere with measurement data. Method selection considers expected targets, ground composition, the ground volume needed and actual access. For the Surveying, determine the conclusions and limits achievable under these conditions. A deeper foundation or different working level may create an additional investigation need. Plan investigation access and borehole points with their locations, depths and known structures. The results undergo specialist interpretation and comparison with the proposed construction task.
Coordinate remediation steps technically
A Clearance plan can define how necessary explosive ordnance services are combined with planned earthworks. The method must suit the specific conditions. Simply watching excavation does not replace proper investigation. Whether a clearance method during construction can be considered is assessed according to the hazard and construction conditions.
The agreed Excavation supervision needs a suitable sequence for the proposed specialist work. The site management team and specialist contractor coordinate working areas, communication and handling of new findings. Plan necessary area clearance or further investigation of findings with its specific scope. For any necessary Ordnance recovery, clarify access, the specialist task and protective measures. Document the status actually achieved. If a suspicious object is found, stop the affected works and notify the police immediately; their instructions determine the next steps.
Next steps
From the property file to coordinated construction
Compile the available file
Send the reports as completely as possible, including maps and appendices. Add a current location plan of the project. If historical area names and current cadastral plots differ, show the known allocation. A recognisable gap in the records is also important information for further planning. During the initial enquiry and document review, assign existing findings to the current construction area. Where underlying information is incomplete, carry out historical research and aerial photograph analysis.
Describe the next ground works
State what will be carried out first and which work steps follow. Proposed depths matter as much as area boundaries. A commission for an excavation does not automatically include every later connection. Consider the individual ground works together before defining the specialist commission. Relate the tasks to the ground volumes actually affected and the investigation status needed before connection works.
Clarify access and responsibilities
Consider access, available utility information and known obstructions for construction. Agree who arranges necessary preparatory services and who receives the results. Agreeing a date does not replace technical prerequisites. Public authority requirements and private service commissions remain separately applicable. Method selection considers targets, ground conditions, interference and required depth. The agreed surveying or suitable supervision addresses these areas; findings and measurement limitations receive specialist assessment.
Hand over results to site management
The documentation should clearly describe the location, scope and limitations of the work performed. The site management team needs these details before dependent ground works. Keep earlier and additional results clearly assigned. If the design changes, check again whether the relevant conclusions still apply. The next decision clarifies further specialist needs for outstanding areas and the coordination required before the next ground works.
Documentation
Commission specialist services and respect responsibilities
Findings and their scope
Under the Bavarian notice in effect since September 2026, local hazard response generally lies with municipalities as public safety authorities. The explosive ordnance disposal service commissioned by the Interior Ministry supports response to specific hazards from legacy ordnance that has been found. Prepare and commission property-specific research, assessment and planned investigation as separate specialist tasks.
Project responsibilities
FONTANA-EOD discusses the specialist services needed for your Ingolstadt project with you. Findings for the area and proposed ground works are the basis. The BFR KMR can support specialist planning; their direct scope concerns federal properties. This does not create a blanket additional investigation duty for every property in Ingolstadt.
A survey report documents methods, areas investigated, findings and their assessment. A clearance record documents clearance work actually performed and its scope. The Clearance documentation remains tied to the associated areas, depths and services. Compare later design changes with this evidence before the affected works. Outstanding tasks remain clear. Bring together technical results, site management requirements and decisions by the responsible bodies for the respective construction section.
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
Identify a report's question
Read the investigation objective underlying the report. A result on ground conditions may be useful for planning while addressing a different technical question. Consider the relevant evidence together. Identify missing conclusions before defining work that relies on them.
Understand investigation reports and their limitationsIdentify unresolved allocations in the file
Missing maps or unclear former area names may make a report harder to use. Record these gaps and obtain the associated documents where available. The specialist assessment can then evaluate the actual relationship. Check the allocation technically against the available maps and current location plan.
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.

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 former commercial sites in Ingolstadt
Does the suspicion described for INquartier apply to all of Ingolstadt?
No. The environmental report concerns the identified planning area and its earlier use. Another property requires consideration of its own findings and specific construction project. The municipality is generally the local public safety authority. If a find is made, notify the police immediately; the public safety authorities and commissioned explosive ordnance disposal service perform their respective hazard response tasks.
Is a remediation plan also evidence of clearance?
No. A plan describes proposed measures. What was actually investigated or cleared must be established from the associated results and their spatial and technical limits.
Which documents help with an initial enquiry?
A current location plan, proposed ground works and depths, and existing reports and historical plans of structures. Identify preparatory ground disturbance and known gaps in the property file too.
Does every former industrial area need surveying again?
Earlier use alone cannot decide this. Existing findings, previous investigations and the planned ground disturbance determine the further clarification needed. The process combines document review, necessary historical research and method selection with investigation or suitable supervision, assessment and documentation. Select the method for the respective targets, ground conditions and interference.
What should you do if a suspicious object is found?
Stop work, leave the object unchanged and keep other people away. Notify the police immediately from a safe distance on 110. Follow the authorities' instructions.
Which factors affect the cost of explosive ordnance assessment?
Research needs, areas and depths, access, structures and the appropriate method determine the work required. Interpretation, documentation and, where necessary, investigation of findings are additional factors. Usable existing reports help define the additional commission. Private specialist commissions are considered separately from the commissioned explosive ordnance disposal service's activities involving legacy ordnance that are free of charge under the Bavarian notice.
What should be done if a remediation area expands?
Compare the new area and ground disturbance depth with existing results. Agree specialist services still needed before the affected works.
Can different investigations concern the same ground disturbance?
Yes. Their respective objectives and conclusions remain separately identifiable; coordinate their prerequisites and sequence.

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.
