Explosive ordnance surveying in the Stuttgart administrative district
Working areas often change after the first construction section: an access road moves, a connection pit is added or the next excavation begins. FONTANA-EOD helps project owners, designers and site managers in the Stuttgart administrative district compare proposed ground disturbance with existing explosive ordnance documents and define investigations required. Send the current construction-phase plan showing areas and depths, together with earlier results reports.

What documents does explosive ordnance investigation need when the construction phase changes?
When the construction phase changes, the current ground disturbance plan, associated depths and complete investigation reports are needed. For an explosive ordnance investigation before construction in the Stuttgart administrative district, the main structure, connections and temporarily used areas are considered according to the actual groundworks. The specialist review compares the next section with the documented scope and defines the investigation still required. An organisational handover does not extend previous investigation conclusions.

Project site
Assign the project location, responsibilities and construction section
Consider spatial differences near Leinfelden
The U5 decision of 15 March 2022 describes different assessments for northern and southern parts of the investigation area. When preparing a section, such boundaries are compared with the proposed ground disturbance. Later changes and investigations actually carried out must be considered using their own documents. The Stuttgart administrative district comprises eleven rural districts and the Stuttgart and Heilbronn urban districts in Baden-Württemberg. The project identifies the municipality, cadastral plots and construction sections affected. Municipal and other specialist bodies are involved according to this location and the project. By contrast, the KMBD at the Stuttgart regional authority is responsible for all of Baden-Württemberg. Regional road construction units address specific geographical areas; their responsibility does not replace this statewide duty. Further locations are available in the regional overview.
Information on explosive ordnance surveying in Esslingen am Neckar, Ludwigsburg, Aalen, Schwäbisch Gmünd, Sindelfingen, Göppingen, Waiblingen, Böblingen and Heidenheim an der Brenz supports preparation of your project enquiry. Documents and planned ground disturbance on the respective property are decisive.
Local context
Bring historical findings and construction sections together
Consider construction design and the work sequence together
The Eastern Construction Unit of the Stuttgart regional authority describes construction design, sequencing and supervision as connected tasks in its road construction projects. It is responsible for the Ostalbkreis district and the Schwäbisch Hall and Heidenheim districts. The official road-planning overview also explains that adjustments arising from the plan approval decision are incorporated into the construction design.
Research into the history of sites in the administrative district must assess specific wartime events and former uses. The Böblingen Town Archive describes the air raid during the night of 7 to 8 October 1943 and the extensive destruction of the area south of Marktstraße. For Waiblingen, an officially published aerial photograph assessment documents the relocation of Elma Fluggeräte from Stuttgart-Bad Cannstatt in 1941 and its manufacture and repair of aircraft parts. These local and use-related details belong in research; your own construction area is investigated with its aerial photographs, records and boundaries. Existing assessments and measures carried out are considered within their own scopes for each construction section.
Include ancillary areas involving ground disturbance
This raises a practical question for explosive ordnance investigation: which ground disturbance is actually to be carried out using the plan now available? A general route alignment is insufficient to describe every connection pit or temporary working area. Such areas belong in the enquiry where ground disturbance is proposed.
Distinguish road construction from the state service
The Baden-Württemberg explosive ordnance disposal service is based at the Stuttgart regional authority and responsible statewide. This duty is distinct from road planning and site management. Existing official information and specialist reports are brought together with the construction sequence; approval of a construction phase does not replace evidence of explosive ordnance investigation.
Retain the distinction between U5 areas in the decision
For the second U5 section from Leinfelden Bahnhof to Neuer Markt, the Stuttgart regional authority's decision of 15 March 2022 expressly distinguishes the northern and southern investigation areas. Following aerial photograph assessments from 2017 and 2018, the explosive ordnance disposal service considered on-site checks unnecessary only in the southern part. In the north, unexploded bombs could not be ruled out in designated areas. For excavation and earthworks in suspected areas, the decision required monitoring by appropriately trained personnel. It also called for checking, in consultation with the explosive ordnance disposal service, whether surface surveying was possible. Such spatial differences must remain identifiable during section handover. The decision at that time does not replace review of later changed ground disturbance or describe today's clearance status.
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 U5 decision of 15 March 2022 records the different U5 areas and their requirements at the time. The Eastern Construction Unit explains its construction design and supervision duties. The official road-planning steps show how the plan approval decision informs further planning. The explosive ordnance task is addressed for each ground disturbance using the relevant documents.
The BFR KMR guidelines on clearance planning connect the investigation task with the subsequent sequence. The guidance on geophysics supports method selection, while that on Documentation supports a traceable handover of results. The DGUV FAQs on explosive ordnance clearance explain occupational safety and suitability of the working method. The Baden-Württemberg state information describes the state's duties.
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
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 carries out the agreed investigation and documentation scope. Official requirements and decisions are clarified with the competent authorities concerned. The documents needed for a particular procedure depend on the location and project. The technical report describes the specialist service performed with its documented area, depth and service scope.
Investigation task
Which specialist task comes next?
Assess measurement conditions for each section
A method's suitability depends on the investigation objective and local conditions. An approach suitable for the first section must be considered separately for another area. Accessibility, surfaces and interfering installations are taken into account. Planning records the conclusion needed for the proposed depths.
For the Surveying, expected target objects, the soil profile, interfering objects and depth of ground disturbance are considered together. Utilities, reinforcement or fill containing metal may affect measurement. Investigation preparation therefore considers the actual conditions of each section. A measurement that can be interpreted well elsewhere provides a basis for the task addressed there. Suitability and limits of conclusions are reassessed by specialists for ground with a different profile or deeper ground disturbance. Areas with restricted interpretation remain identifiable in the results plan with their locations and further needs.
Select investigation methods according to local measurement conditionsConnect outstanding areas with their next ground disturbance
If an area cannot initially be investigated sufficiently, this limitation remains documented. Describe the works planned there later. Specialists develop the next approach from this. General construction supervision or organisational approval does not replace this review of the explosive ordnance task.
Compare investigation methodsProject types
Connect the next construction section clearly with results
Assign historical findings to the sections
Existing assessments are provided with their maps and original area boundaries. Different conclusions within a project remain visible. Identify which part is to be addressed next. The specialist review can then identify the findings applying to that section and the question still outstanding before ground disturbance.
A linear project may bring together different investigation stages. An older aerial photograph assessment may concern a longer corridor, while technical surveying covered only individual construction areas. Assign both types of document to their original boundaries. If properties have since been divided or area names changed, explain the assignment on a current plan. A section may thus contain usable earlier work and outstanding areas at the same time. For the latter, define the further historical or technical clarification needed before the planned ground disturbance.
Arrange specialist assessment of historical evidence
Describe the forthcoming ground disturbance completely
Besides the main structure, the next work stage may include connection pits, anchors or temporary trenches. Draw these areas with their proposed depths. Actual work in the ground is decisive. A shared site name does not replace precise definition of the areas to be investigated.
Also draw the ground disturbance needed to establish the construction area. This may include drainage, temporary utilities, new foundation points or works on site access. Use as a storage area alone does not describe ground disturbance; excavation or soil replacement needed for it, by contrast, has a specific location and depth. Mark these differences so that the investigation commission covers the works actually forthcoming. If ancillary areas are planned only later, their needs are compared with existing results before they are created.
Compare specialist services
Base handover on the documented scope
Hand over results reports and plans so that the next site management team can identify its working area. Reference elevations, boundaries and limitations used are retained. Outstanding areas are identified. Documentation thus supports further construction without turning a partial investigation into a conclusion about the whole project.
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.
Clarify preparatory work in the programmeAgree a clear scope and schedule
A sound workflow distinguishes work already clarified technically from outstanding prerequisites. If an area will be accessible only in part, commissioning must take this into account. Handover and assessment of results also need time in the construction sequence. Dates and the work involved are agreed after clarifying scope, access and required prerequisites. For the section concerned, establish which documents must be available before work starts and who hands the results to the contractor.
Discuss the scope and schedulePrepare the construction project
What should be clarified when the construction phase changes
01
Define the next section
Mark the area where excavation, drilling or foundation works are to take place next. State the planned depths. A section name alone does not explain whether, for example, a lateral utility crossing or additional pit also belongs in the commission.
An excavation is described with its working spaces, and a utility with its route and connection points. For deep foundations or anchors, identify proposed starting points and volumes of ground. For borehole clearance, the location and documented depth range must be traceable. Any necessary deep surveying is matched to the defined investigation task. For area clearance, the agreed area is specified. Scope and results are documented so that a later spatial change can be reviewed specifically for its additional investigation needs.
02
Draw temporary ground disturbance
The planned works matter for areas needed only temporarily too. Describe soil replacement, anchors or drainage trenches where proposed. Temporary use creates neither an automatic investigation duty nor an exemption from specialist review.
03
Hand over existing results completely
Provide results plans and reports with their appendices. The next site management team must be able to identify which areas and depths were investigated and where limitations apply. An abridged note without spatial reference may make this assignment difficult.
04
Identify changes from the commission
If ground disturbance moves or becomes deeper, we compare the change with the documented investigation scope. This establishes whether existing results are sufficient or further clarification is required. A new plan number alone does not justify additional measurement.
Project documents
Documents that establish the next step
Use the same names between construction sections
Areas and connections should be recognisable across the investigation plan, construction-phase plan and results documents. If names change, the assignment is provided with them. A clear overview makes handover between contractors easier. Unclear boundaries are clarified by specialists before the next ground disturbance.
The elevation reference used is handed over with the depth information. A figure below ground level refers to the ground condition at that time. After filling, excavation or demolition, this reference is related to today's situation. If a planned connection becomes deeper, the additional volume of ground affected is compared with the investigation report. Specialist planners and site management receive the same current status. If anything is unclear, the addition required is clarified before the ground disturbance affected, while usable information about other areas continues to be used.
Communicate changed construction conditions in good time
Filling, demolition or newly installed structural elements may change investigation conditions. Identify known changes from the earlier status. The specialist planner assesses their significance for the forthcoming task. An old report is neither discarded outright nor reused without review. For clearance work carried out, the associated clearance record is consulted with areas addressed, methods, findings and outstanding tasks. Its location and depth references are retained in this comparison.
Construction sequence
Coordinate investigation and construction sections
Compare together before section handover
Bring the current construction-phase plan and existing results documents together. Identify additional areas and changed depths. Specialist planners and site management clarify which conclusions already cover the next works. Tasks still required are agreed with a traceable scope before this ground disturbance.
The tender describes available supporting information and specialist services still to be provided. Identify the investigation objective, areas, depths, known interference and results handover needed. All bidders need the same design revision and available preliminary reports. For several construction phases, state the sequence and prerequisites for access and preparatory works. Missing documents or inaccessible areas are recorded as outstanding tasks. The commissioned service can then be assigned to the next construction section instead of repeating an earlier commission without checking its scope.
Retain the context during a last-minute change
A relocated pit or deeper connection is described as a change before construction. The specialist review compares it with the previous commission and results. Usable documents are retained. If additions are required, they relate to the specific outstanding task in the changed section.
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
Fit the investigation into the construction sequence
Identify accessible areas early
Check with the specialist planner which areas are accessible before earthworks. Surfacing, installed structures and metal interference may affect the suitability of surveying. A gap in the construction programme does not make an unsuitable method technically suitable.
Access and preparation are agreed with the contractor before deployment. These include usable working areas, utility information and known installations. If construction alters an area during the investigation, the specialist contractor must be informed. Whether results already obtained can continue to be used depends on the change and task investigated. Access on foot and by vehicle, and other work taking place at the same time, are also coordinated. Those responsible for site organisation and occupational safety receive the information relevant to their tasks.
Assess remaining areas separately
If a complete preliminary investigation is not possible, the outstanding areas are described. Whether ordnance surveying during construction or another approach is suitable requires specialist review. Visual observation of excavated material alone does not replace the surveying needed.
Suitable excavation monitoring receives a defined specialist commission for the working areas affected. Site management agrees the work sequence and communication with the specialist contractor. When investigating a finding, the access and protective measures required for further work are defined. A suspicious find is reported to the police immediately; the responsible bodies arrange subsequent steps. New findings are assigned to the respective area and considered when work continues. Handover identifies work carried out, results and measures still needed for the next ground disturbance. Any necessary Ordnance recovery is coordinated with its specialist task and responsibility.
Separate investigation from authorisation to work
The clearance documentation describes the result of the explosive ordnance measure within its scope. Site organisation, traffic safety and other work authorisations have their own tasks alongside it. For handover, the documents required for each should be clearly assigned.
Next steps
How to prepare section coordination
Include the construction-phase plan
Mark the current section and proposed subsequent sections. Identify changes from earlier plans. Initial contact records the project location, construction section and decision needed. The document review assigns existing explosive ordnance reports, site plans and conditions to the current construction phase.
Explain the earthworks
Add areas and depths of ground disturbance, including ancillary works needed. Unspecified details remain outstanding. Where historical information is missing, research and aerial photograph analysis are carried out. Method selection follows target objects, the ground, depth range, interference and access.
Assign results
Include existing explosive ordnance documents and assign them to the respective working areas. The agreed surveying or suitable monitoring is carried out within its defined scope. Assessment assigns findings and measurement limitations to the planned ground disturbance.
Agree handover
Discuss which investigation is needed before the next work stage and which documents site management should receive. Documentation and plan appendices record the scope carried out. The decision on subsequent steps clarifies further measures or coordination for outstanding areas; those responsible receive results before the subsequent works affected.
Documentation
A traceable status for the next construction section
Findings and their scope
A useful handover shows both investigated areas and questions still outstanding. Results documents are compared with the current ground disturbance plan for this. If different contractors work in sequence, they should be able to refer to the same area names and elevation information.
Project responsibilities
For local projects, the Stuttgart, Heilbronn and Aalen pages add to regional preparation. Belonging to an administrative area alone says nothing about suspicion of explosive ordnance. Existing findings for the specific area and the technically defined investigation scope remain decisive.
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
Assign planning, investigation and construction organisation
The documents for a construction section serve different tasks. The design describes the proposed ground disturbance; the investigation report describes services carried out and results. Site organisation addresses further prerequisites for construction. These tasks remain identifiable during handover so that no individual document is given a broader conclusion than it actually supports.
Understand investigation reports and their limitationsRetain limits of results for later contractors
The limitations of earlier investigations must remain clear even when the contractor changes. Pass on complete plans, legends and the underlying ground disturbance. Identify outstanding areas. Before a different use, check whether existing conclusions are suitable for it. A change of contractor alone does not justify new measurement. What matters is whether existing results cover the proposed ground disturbance under its actual conditions.
The survey report identifies methods, areas investigated, findings and measurement limitations. A clearance record documents clearance works carried out within their defined scope. The report and plan appendices are kept together with the ground disturbance plan used. For later additions, it remains clear which document continues to apply and which has been added. Where several contractors are involved, the next site management team receives the complete applicable documents. Remaining outstanding areas are assigned to the next work stage needed. The project file thus records both the investigation status reached and questions still to be addressed. The Clearance documentation relates to the documented area, depth and scope of services.

Process and documentationQuestions from planning
Questions about investigation across several construction phases
Does a result from the first section apply to the whole site?
Only insofar as its documented investigation scope actually covers the later works. The area, depth and limitations are compared with the next ground disturbance. Belonging to the same construction project is insufficient.
Must temporary construction areas always be investigated?
This cannot be determined from the name alone. Describe the ground disturbance proposed there and existing findings. Specialists then review investigation needs. Agree these before creating the areas. Preparation brings together the current site plan, depths, proposed work stages and existing reports with their appendices.
Is the construction unit also the explosive ordnance disposal service?
No. Construction planning and execution are distinct from the statewide explosive ordnance disposal service's duties. Both may be based at the Stuttgart regional authority but have different specialist tasks.
How are connection pits changed at short notice addressed?
The changed location and depth are compared with the existing investigation plan. Specialist review clarifies whether previous results apply or additional measures are needed. A verbal assignment to a section already addressed is insufficient. The sequence connects document review, necessary historical research and method selection with investigation or suitable monitoring, assessment and documentation. Methods and their measurement limitations are defined by specialists for local conditions and recorded in the results.
What should be done if a suspicious object is found?
Stop work in the affected area immediately. Do not touch or move the object; leave the danger area, keep your distance and keep others away. Notify the police on 110 immediately. The police arrange the next steps.
Which ancillary areas belong in the ground disturbance plan?
All areas where the next works will disturb the ground, such as additional pits, anchors or drainage trenches.
Why do reference elevations matter during handover?
They help compare documented investigation depths with planned works. Unclear or different elevation references must be clarified.
What determines the work involved in the next construction section?
The research needed, area and depth, accessibility and interference are decisive. This also includes analysis, documentation and any further investigation of findings. Complete, usable preliminary reports help define the supplementary commission. Scope and prerequisites are discussed before commissioning; state and private services remain separate commissions.
