The explosive ordnance disposal service at the Stuttgart regional authority is responsible statewide. The specific ground disturbance remains decisive for technical preparation: area, depth, terrain and existing findings are considered together. Commissioned specialist services and the duties of the responsible authorities are distinguished traceably in the project record. For assignment, the municipality, property and planned groundworks are identified together. For a project spanning several municipalities, the respective contacts and documents are assigned to individual sections.
The existing overviews for Stuttgart administrative district, Karlsruhe administrative district, Freiburg administrative district, Tübingen administrative district lead to the associated local information. Select the area of your construction project; the specific municipality and properties affected remain decisive for the enquiry.
The city encyclopaedia of Karlsruhe City Archive documents air raids on Karlsruhe in both World Wars. For the First World War, it names military offices, Deutsche Waffen- und Munitionsfabrik and the railway junction as target contexts. For the Second World War, it describes heavy raids in 1942 and 1944, including damage to businesses in the Rhine port and in urban districts. For a present-day construction project, such historical findings are connected to the specific location, former uses and documented ground changes. Records, wartime aerial photographs and existing assessments help define the outstanding questions for the construction area. The investigation is prepared using this information and the planned ground disturbance.
The explosive ordnance disposal service based at the Stuttgart regional authority is responsible for all of Baden-Württemberg. It supports police authorities and undertakes, in particular, rendering ordnance safe, transport of recovered ordnance and destruction. Aerial photograph analysis by the KMBD is subject to a charge.
Property owners must arrange searching for and recovery of explosive ordnance themselves. The KMBD offers this work within its capacity, with costs reimbursed; if no capacity is available, private explosive ordnance clearance contractors must be commissioned. FONTANA-EOD plans the commissioned works according to investigation needs and coordinates the necessary steps with the responsible bodies.
For scheduling, check the official application documents and current processing times early. A planned construction start replaces neither necessary preliminary investigation nor specialist clarification of existing grounds for suspicion.
Information from the KMBD Baden-Württemberg helps assign the responsible bodies and preliminary investigation required to the planned project.
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.
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.
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 Baden-Württemberg explosive ordnance disposal service explains the statewide allocation of duties. The forms for preliminary investigation and updating connect the enquiry to the specific construction project. The KMBD questions and rules of conduct describe, among other matters, how to report a find. This information is brought together with existing project documents and forthcoming groundworks.
The BFR principles of clearance planning structure the investigation objective and scope of services. The BFR guidance on geophysics concerns methods and measurement conditions; the BFR guidance on documentation relates results to plan appendices. Outside their federal scope, the BFR KMR provide technical guidance. Local requirements and project-specific coordination remain decisive.
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.
The project owner describes the project and provides existing project documents. The operator adds requirements for use, access and timing. A coordinating contact agrees the tasks assigned to them with those responsible. Before commissioning, the missing information, who obtains it and the decision the result is intended to prepare are recorded clearly.
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.
The private explosive ordnance specialist contractor addresses the agreed investigation and documentation scope. Official requirements and decisions are clarified with the respective responsible bodies. The documents needed for a specific procedure depend on the location and project. The technical report describes the specialist work carried out; its conclusions are not presented without review as general permission for further groundworks or as an authority's decision. In Baden-Württemberg, the KMBD at the Stuttgart regional authority is responsible statewide. The responsible police and local police authorities are involved through the designated reporting procedures. For an actual find, KMBD specialists determine its further handling. The private specialist contractor and those responsible for the project coordinate their respective commissioned works with these state duties.
The available findings and planned ground disturbance determine the specialist task. The technical approach follows the conclusion needed for the specific groundworks. A slope or surfaced area alone does not determine a method. Local conditions are considered together with the objective and scope.
Compare methods according to the task and conditionsInstalled structures, terrain and accessible areas may affect execution and interpretation. The specialist planner describes these conditions. Areas not sufficiently covered remain identifiable in the results, with further work agreed for them. A general location or merely watching earthworks does not replace the specialist evidence required.
Compare investigation methods
Existing aerial photograph assessments and associated statements are read together with the current construction plan. Conclusions for the specific area and their prerequisites remain identifiable. An older record may contain important supporting information. For the current task, check whether it matches the proposed construction project and what updating or further clarification is needed.
Arrange specialist assessment of historical evidence
Show excavations, trenches, boreholes and preparatory ground disturbance with their depths. Terrain and accessibility also belong in the enquiry. The specialist planner connects these details with existing findings. A general landscape description determines neither suspicion of explosive ordnance nor the appropriate investigation method for an individual area.
Compare specialist services
Documentation shows which areas were addressed, to what extent and what limitations remain. It is handed over with the associated site plans. Additional works are compared with it. Site management thus receives a traceable basis for the specific section and can coordinate outstanding tasks selectively.
Document findings and their limitationsExisting development and terrain help determine how an area can be investigated. Whether there are grounds to suspect explosive ordnance must be checked separately. A sloping site or proximity to a river alone does not establish them.
For industrial, commercial and logistics projects in the Mannheim, Heidelberg and Karlsruhe areas, existing utilities, foundations and filled working areas may affect measurement conditions. Historical documents and current site plans should be considered together.
For long routes or phased development, define which areas will be accessible when and actually need investigating.
Infill development, underground car parks and infrastructure in densely developed areas require a precise description of ground disturbance. Neighbouring buildings, reinforcement, shoring and existing traffic areas may restrict surveying.
Planning and investigation must therefore also cover the depths and peripheral areas later affected by foundations, anchors or excavation support.
On uneven or terraced ground, safe access, measurement paths and elevation references need particularly careful planning. Machinery selection and area productivity depend heavily on the specific conditions.
For projects around Freiburg, Ulm or Lake Constance, possible grounds for suspicion are assessed for the individual property just as in a major city.
Show the property affected with its boundaries and the ground disturbance actually proposed. A shared file reference helps assignment but does not replace a complete spatial description. Preparatory works and additional construction areas also belong in the comparison.
The statement may identify further work required. Check which of those tasks have already been carried out and documented. The associated reports remain available with their appendices. A stated requirement and evidence of it being addressed are different parts of the project information.
Determine which next work needs a conclusion. Different sections may have different access and depths of ground disturbance. Keep the investigation status separately identifiable for each area, even where commissioned together.
Mark changes from the project already considered. Additional areas, greater depths or different preparatory activities may require a fresh comparison. Existing results are considered within their actual scope.
The investigation needed depends on existing information and planned groundworks. Methods and scope of work are defined on this basis.
Historical wartime aerial photographs and supplementary documents help locate anomalies spatially. Existing KMBD assessments are compared with the present-day construction project.
For development and conversion sites, a method suited to the measurement environment is selected. Accessibility, conductivity, metal installations and possible interference affect interpretation.
For pile foundations, sheet piling or deep excavations, investigation needs are clarified for the depth range affected. A shared location and elevation reference is essential, particularly where terrain varies.
For defined suspected areas, the clearance objective, accessibility and working boundaries are specified. Later documentation must show the area actually addressed.
Where preliminary investigation is restricted, coordinated monitoring of earthworks may be required. Site management, equipment operators and technical supervisors need clear communication and decision procedures.
If anomalies are identified during investigation, the next steps are agreed with the responsible bodies. The agreed and permissible commission scope remains decisive. The responsible organisation undertakes rendering ordnance safe and destruction.
Describe available access roads, working areas and visible obstacles. Specialist planners and contractors agree the prerequisites needed for the proposed service. Access not yet available remains visible in the sequence. A planned date is considered together with the prerequisites actually met for the section concerned. The results file connects the site plan, areas and depths with methods, measurement conditions and findings assessed by specialists. Volumes addressed and still outstanding remain distinguishable. For commissioned clearance works, the clearance record with associated location and results information belongs in the evidence file. Designers and site management can compare the next activity with this documented scope.
Clarify which documents are already available and which response is still outstanding. The commissioned service receives a defined task and traceable prerequisites. Official responsibilities remain separately identifiable. Assumed dates are coordinated with the respective procedure without treating general information as a binding commitment for your own project. During phased handover, the report and plan appendices are passed on with outstanding tasks. Limitations caused by access or interference remain assigned to the respective volume of ground. Newly involved contractors receive the stage actually reached for their next task.
Send the current site plan with proposed depths and existing assessments and reports. Identify the planned sequence and outstanding information. Joint coordination defines the specialist task. Necessary prerequisites and further steps are thereby connected to the specific construction project.
Check with those responsible whether existing documents still match the project and require updating. New areas or deeper ground disturbance are identified. The specialist planner compares the previous coverage. Existing results continue to be considered within their actual scope and documented limitations.
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 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 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 surveyingUnder 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 limitationsFor 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 interventionsIf 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 constructionExisting aerial photograph assessments and official statements are read with the current ground disturbance plan. Their tasks and spatial coverage remain identifiable. Technical planning builds on these findings and describes the further conclusion needed for the proposed groundworks.
Available access, installed structures and local interference affect the investigation. The appropriate approach is matched to the investigation objective. An earlier method or general area name does not automatically determine the method for a new task.
Areas not sufficiently covered remain documented as outstanding tasks. Supplementary steps receive a defined spatial and technical scope. A partial report thus becomes usable for further planning without extending its conclusions to areas not yet investigated.
Provide the statement, existing reports and current ground disturbance design with their appendices. Unclear spatial references and missing documents are identified. Initial contact includes the project address, construction phase and forthcoming groundworks. Existing information and specialist reports are reviewed with their appendices against the current plan revision, spatial coverage and outstanding questions. The first coordination clarifies the conclusion needed for the next ground disturbance and which documents are still missing.
Where supporting information is missing, the necessary historical research or aerial photograph analysis is carried out for the specific construction area. Available records, wartime aerial photographs and earlier maps are connected to today's location and the investigation question. Recorded war impacts, changes of use and documented ground changes are located spatially. The findings are analysed for further investigation planning; existing information that is already sufficient may continue to be used.
Describe which conclusion is needed for which ground disturbance. Investigation scope, prerequisites and the tasks of those involved are agreed traceably. The appropriate method is defined using the investigation objective, ground disturbance plan, existing findings and local conditions. Access, installed structures and possible interference are considered. The specialist contractor, designers and site management agree preparation, scope of services and the handover timing needed. Necessary official notifications are assigned to the specific activity.
Clarify access, construction phases and necessary notifications before the proposed start. Design changes are passed to those affected in good time. Specialist personnel carry out the agreed surveying or technically defined monitoring using the coordinated method. Data and findings are recorded with their locations and actual scope of work. Limitations caused by access or interference remain documented. Unexpected conditions are communicated through the agreed contacts and assessed by specialists before any departure from the planned work.
The specialist contractor assesses recorded data and findings according to the investigation objective, method and actual conditions. A measurement anomaly is interpreted without identifying it as a particular object solely because it occurs. The stage reached, interference, outstanding areas and additions required are documented in the report with associated plans. The assessment describes the technical conclusions reached and questions needing further clarification.
Reports and site plans show the scope actually addressed. Outstanding areas or those with restricted interpretation remain identifiable for the next works. The report and site plans connect methods, assessed results, volumes addressed and limitations. Designers and site management compare the next groundworks with this status. Additions needed or further official coordination are clarified before the ground disturbance affected. Documentation remains available for later design changes and newly involved contractors.
The site plan, preliminary investigation and investigation report must describe the same construction project. If the design or construction area changes, the documents must be supplemented accordingly.
Mark the whole construction area, including site establishment and planned ground disturbance. For routes, bridges or retaining structures, individual points and peripheral areas also belong in the description where actually affected.
According to the KMBD, preliminary investigation generally applies to the construction project for which it was issued. If delays occur, an update should be obtained after three years at the latest. A material design change must also be assessed for its implications for investigation scope.
Reports, plans and records should identify the investigation method, working boundaries and limitations. A blanket conclusion for the whole property would be insufficient if only specific areas or depths had been investigated.
Evidence for the projectThe KMBD forms and information on updating explain how preliminary investigation relates to the planned construction project. If the design revision changes, the areas affected and outstanding questions are identified for further coordination.
The results report records the task carried out with its spatial scope and limitations identified. The explosive ordnance clearance service's statement remains identifiable as a separate basis. Handover makes clear which requirements have been addressed and which questions remain outstanding for the next groundworks.
The agreed private specialist service is connected to the proposed ground disturbance and respective prerequisites. Official duties remain with the responsible bodies. Changes to the construction plan are reviewed to determine whether existing results still apply and what additional coordination is required for the areas affected.
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 taskWe 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.
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.
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.
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.
You can enquire about projects in Stuttgart, Mannheim, Karlsruhe, Freiburg, Heidelberg, Heilbronn, Pforzheim, Reutlingen and Ulm, and in the surrounding districts. These include, for example, Rhein-Neckar, Karlsruhe, Ortenau, Böblingen, Esslingen, Rems-Murr, Alb-Donau, Konstanz and Bodenseekreis.
A former garrison site requires different documents from development of a new residential neighbourhood. Describe the location and proposed works and include existing reports. Further investigation needs can be determined from this.
The official validity information relates the assessment to the planned project for which it was issued. When changes or delays occur, the plan revision and updating needs are therefore reviewed. The existing document is passed on with its appendices. Its conclusions are not extended to other ground disturbance solely because the address is the same.
Understand investigation reports and their limitationsTerrain affects access and technical execution. Suspicion of explosive ordnance is assessed using the findings available for that purpose. Both questions are brought together during preparation but retain their respective purposes. The project describes specific groundworks rather than deriving a blanket investigation conclusion from a landscape description.
Understand the service scope
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 assessment
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.
Assess investigation reports


Historical assessment, technical investigation and further work answer different questions. The service overview helps distinguish these tasks in an enquiry.
Compare services
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 documentationHere you will find answers about the influence of terrain, use of earlier assessments and conduct when something is found.
No. Terrain affects accessibility, surveying and technical execution. Suspicion of explosive ordnance is based on historical or other specific indications; terrain and contamination must be assessed separately by specialists.
It should be reviewed for spatial coverage, relation to the project and currency. In your enquiry, identify earlier file references and include existing documents so that duplication and outstanding areas can be recognised.
Do not touch or move it, keep your distance and notify the police or local police authority immediately. Do not take suspicious objects to a police station yourself. The police arrange involvement of the KMBD.
The KMBD, responsible statewide, is based at the Stuttgart regional authority. Its current information describes the application, assessment and further duties.
According to the official information, property owners arrange this work. The KMBD may act within its capacity with costs reimbursed; otherwise, private specialist contractors must be commissioned.
Describe the terrain, available access roads and working areas, and visible obstacles. These details are compared with the investigation objective and prerequisites needed.
Provide new areas, relocated ground disturbance and changed depths. Existing assessments and results are checked for coverage and any updating needed.
An assessment and a report on completed work have different tasks. Construction preparation considers the complete documents with their respective scopes and limitations. The work involved and costs depend on area or number of points, depth of ground disturbance, documents available, access and measurement conditions. Preparatory works and results documents needed are described in the scope of services. Scheduling identifies the section needed first and the prerequisites to be met before work.
The KMBD rules of conduct when ammunition is found explain reporting and protection of others. Suspicious objects remain untouched where found; the police or local police authority are notified.
Describe the site plan and proposed groundworks clearly.
Identify existing reports, terrain and possible obstacles. Also state which earthworks are to begin first and which areas are not yet accessible. Necessary preparatory works and results handover can then be coordinated in good time.
Provide the site plan, project description, depths of ground disturbance and existing preliminary investigations. Add information on terrain, access and the start of construction. The investigation needed can then be incorporated specifically into design and construction.

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.
