Explosive ordnance surveying for buildings and routes in Bielefeld
For a new building, groundworks for utilities and connections must be considered alongside the foundations. FONTANA-EOD supports preparation of explosive ordnance assessment for your project in Bielefeld. Planned interventions are compared with existing results and the status of the official procedure.
Consider foundations and connections together.
Distinguish new interventions from existing infrastructure.
Clarify responsibilities at connection points.
Assess the construction project
Identify the complete building area and utility routes
A new building may require connections outside its foundation area. For your project in Bielefeld, buildings, new routes and works on existing utilities are considered together with the available documents. The appropriate application procedures and outstanding technical tasks remain distinguishable. Agree the necessary applications and investigations before the first ground intervention they concern.

Project site
Connect the site with the specific construction task
Consider Bielefeld’s application procedures together
The service portal distinguishes general construction projects from utility route construction. For an interconnected project, these tasks are coordinated with the Feuerwehramt. Plans for both areas and existing results assist the technical enquiry. The groundworks actually proposed and questions still outstanding remain decisive. Bielefeld is an independent city in North Rhine-Westphalia and belongs to the Detmold administrative district. Technical support from the Westfalen-Lippe explosive ordnance disposal service of the Arnsberg district government is coordinated through the locally responsible city department.
For an enquiry from the city centre, Brackwede, Schildesche, Heepen, Stieghorst, the Senne area and Sennestadt, Gadderbaum or Dornberg, the precise project address and a site plan are needed. Describe buildings, routes and their shared connection points. For commercial, railway or infrastructure sites, identify current use, available access and planned working areas. Methods and scope are related to that information.
FONTANA-EOD has a location in Wesseling. For projects in Gütersloh, Herford, Bad Salzuflen, Schloss Holte-Stukenbrock or Enger, state the relevant municipality and specific project location. These neighbouring places have their own municipal responsibilities. For other projects in Ostwestfalen-Lippe too, the appropriate procedure is clarified using the actual location and proposed groundworks.
Local context
Identify application procedures and historical information
Local applications and former uses
Bielefeld’s service portal distinguishes applications for general construction projects and utility route construction. For routes, it particularly requires the alignment, associated ground interventions and existing utilities; new and existing intervention areas should be distinguishable. Local responsibility lies with the Feuerwehramt, which works with the Westfalen-Lippe explosive ordnance disposal service. The Bielefeld City Archives document the air raid of 30 September 1944. For present-day construction projects, historical information is related to the actual property. Former industrial and commercial sites in the Senne area, Brackwede or western Bielefeld, and railway and shunting areas at the main station, require comparison of available use and construction records. Reconstruction, fill and later changes in residential and mixed-use areas may conceal earlier terrain and building conditions. The findings needed for the proposed intervention are determined from the specific records, existing results and current plans.
Industrial building and changed drainage
If a new industrial building with changed drainage is planned, record connection excavations and utilities as well as the foundations. Works on an existing route may require additional investigations. Show these interventions together so that building construction, civil engineering and the responsible authorities can coordinate their tasks. The municipal route application marks existing and new intervention areas differently: ground interventions in existing routes or excavations in black, those in new areas in red. As-built plans and proposed excavations are submitted together. The colours describe the planned intervention, not the result of an explosive ordnance investigation.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For commissioned activities, the applicable specialist requirements and questions of permits, qualifications and responsibilities are clarified. The scope of services actually proposed is decisive. A general company description does not replace assessment of whether the respective tasks and interfaces are appropriately described for the specific project. Company authorisation, competence and appointment of responsible persons are assigned to activities requiring a permit. The prerequisites for the narrowly limited private North Rhine-Westphalia exceptions are checked before a corresponding agreement.
Link occupational safety to the construction sequence
Risk assessment, work areas and communication must fit the proposed activities. Specialist ordnance work is coordinated with the other construction work. Site organisation, traffic safety and further technical specialist assessments retain their own responsible parties. Joint coordination brings information together without equating different tasks. Employers assess the risks of their respective activities and agree the protective measures required at interfaces. If conditions change, the assessment is reviewed for the affected work. Information routes and contacts must be clear to those involved on site.
Use technical findings correctly
A measurement anomaly first requires technical assessment; its appearance alone does not identify it as explosive ordnance. For an actually suspicious object, the intended reporting channels and measures of the responsible authorities apply. Investigation reports identify the scope addressed and limitations so that results are not extended to uninvestigated areas or later plan changes. If a suspicious object is found, work in the affected area stops and distance is maintained. The object remains untouched. Notify the fire service control centre or police immediately; in an emergency, call the police on 110. Further securing and specialist handling are undertaken by the responsible authorities.
For general construction projects and utility routes, the City of Bielefeld service portal provides the corresponding application procedures. The City of Bielefeld Feuerwehramt explains local tasks and necessary documents. The permissible scope of private activities is clarified using the KampfmittelVO NRW for the specific commission.
For investigation planning, the objective, area and suitable methods are considered together; the BFR KMR: principles of clearance planning and BFR KMR: geophysics provide the technical basis. Results handover is coordinated with the BFR KMR: documentation. For the private NRW activities covered by these provisions, the KBD North Rhine-Westphalia: guidance for downhole detection and explosive ordnance clearance during construction and task-specific DGUV: explosive ordnance clearance FAQ are used for planning and occupational safety.
The BFR KMR are used as technical guidance; locally applicable requirements and responsibilities must be clarified separately.
The permit, qualifications and responsibilities for the specific activity are assessed under the Explosives Act and the First Ordinance to the Explosives Act. The risk assessment under Section 5 of the Occupational Safety and Health Act relates to the planned activities. The DGUV Information 201-027 addresses preventive investigation and clearance of conventional explosive ordnance and defines its scope. The references it explains to DGUV Regel 113-003 concern specific activities involving explosives; they are not applied indiscriminately to every construction investigation.
For private activities, the requirements of the exceptions under the KampfmittelVO and the official guidance are related to the construction task. The narrowly defined exceptions concern downhole detection in specialist foundation engineering and explosive ordnance clearance during construction under the respective applicable conditions. The site conditions assessed by the state and authorisations required must be in place. Specific indications of ordnance contamination are handled through the responsible state procedure. Before opening up a location indicated as suspicious, the appointment is agreed with the responsible municipal authority; any notifications required under explosives legislation must also be observed.
Working together
Distinguish the tasks of client, designers and specialist contractor
Client and operator
The client describes the project and provides the existing project documents. The operator adds the requirements for use, access and timing. A named contact coordinates the assigned tasks with those responsible. Before commissioning, a clear record is made of which information is missing, who will obtain it and which decision the results are intended to inform.
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 company addresses the agreed investigation and documentation scope permissible for the activity. Official requirements are clarified with the City of Bielefeld’s Feuerwehramt as the responsible special regulatory authority. The Westfalen-Lippe explosive ordnance disposal service of the Arnsberg district government supports municipal processing. FONTANA-EOD’s report documents the specialist work actually performed, its purpose, areas addressed and remaining limitations. The responsible project participants relate that status to the next construction task and decisions still needed.
Investigation task
Which specialist task comes next?
Compare the previous application area with the new plans
Place the assessment alongside the current building or route plan. Identify additional working areas and changed alignments. Any local supplementary requirements remain to be clarified for the specific project. A private enquiry does not replace processing through the responsible Feuerwehramt.
Assess historical documentsDefine the specific investigation task
Utilities, metal installations and different depths may influence the technical task. Describe the ground volumes actually needed and known conditions. The suitable method is matched to these. Permissible private supplementary services remain separate from state tasks and outstanding official decisions.
Compare investigation methodsProject types
Clarify the interfaces between buildings and site servicing
Show the building connection in both plans
A utility connection to a building often concerns building construction and civil engineering together. Mark the connection excavation with its dimensions and depths in the shared plans. A report for the foundation area is checked for its actual boundaries. Merely mentioning the connection in a construction commission does not establish a technical investigation of that area. Identify which trade constructs the connection excavation and who receives its investigation status before work starts. If the entry point into the building moves, compare its new position and depth reference with the previous result.
Specialist services and investigation tasks
Distinguish new works from existing routes
An as-built plan describes existing infrastructure. Show the planned repair, rerouting or lowering additionally. New excavations and lateral working areas may differ from the earlier intervention. Keep these differences visible on the plan so that the findings needed are not inferred solely from the old utility alignment.
Provide specialist supervision of excavationInclude crossings and chambers
A route is technically more than a line. Add chambers, crossings and larger connection points with their proposed depths. Earlier results are related to each affected subarea. This keeps clear where existing findings apply and which additional questions must be clarified before execution.
Specialist services and investigation tasksPreparation
Prepare the scope and commission together
For commissioning, the investigation objective, existing findings and local procedural status are brought together. Buildings, utility routes and connection excavations remain identifiable with their respective groundworks.
Establish what needs to be known before commissioning the work
The commission first needs to clarify which decision is to be prepared. Is the task an initial assessment of existing documents, investigation of a particular area, or further work on a finding already assessed? These tasks require different evidence. A general wish for safety does not yet describe an executable investigation scope. The enquiry therefore identifies the groundworks, location, depth and findings available. Suitable specialist work and results documents needed are agreed on this basis. For a quotation, provide complete reports with their plan attachments and the current construction design. Identify the findings required for the next contract award. Where building and infrastructure works are commissioned separately, shared connection points and outstanding investigation areas are explicitly assigned.
Define the specialist taskCoordinate preparatory work with the investigation
The access and measurement conditions required are clarified before the appointment. These may include areas to be kept clear, available utility information and coordination with other trades. The preparatory work actually needed follows from the chosen method and site. Surface changes or additional ground interventions are not undertaken independently merely to prepare a measurement. Their sequence is agreed with specialist planning and those responsible. Identify foundations retained, utilities and the areas actually available at the appointment. The type and scope of preparatory services needed are agreed with those responsible. If additional working areas are required, their location is compared with the plans before investigation. Changes to the ground follow the specialist sequence clarified for them.
Clarify preparatory work in the programmeAgree a clear scope and schedule
A reliable sequence distinguishes work already technically clarified from outstanding requirements. If an area will be only partly accessible, this must be considered in commissioning. Results handover and assessment also require time in the construction sequence. Specific coordination connects the described scope with access, documents, execution conditions and the decision date needed. Area, depth, method, accessibility, assessment and documentation are particularly relevant to costing. The Feuerwehramt advises submitting an application no later than three months before construction starts; the service portal gives an approximate processing time of eight weeks. Clarify the current official status early. The execution date for a private specialist service is coordinated separately with that status and availability of the investigation areas.
Discuss the scope and scheduleTasks at the site
Groundworks associated with buildings and site servicing
01
Building connections
Mark where utility lines reach the proposed building and which excavations are planned for them. The connection area may differ from the main excavation or investigated foundation area. Enter these interfaces in the plans of both trades involved. Mention in the service specification alone is insufficient. Relate the plans and results needed to each entry point. A shared connection excavation is shown with its complete dimensions. If the building plan changes later, new peripheral areas can then be identified and technically clarified before the affected works.
02
New utility routes
Show new routes including chambers and crossings. State the proposed depths and lateral working areas needed. The alignment alone does not show how large a connection excavation will be. Therefore add the dimensions of proposed ground interventions. Construction conditions involving temporary utilities or trenches open in sections can also be represented. Record which area will be available at the planned investigation appointment. If the route moves, incorporate the changed areas visibly in the updated plan.
03
Works on existing routes
Distinguish the existing installation from the newly planned groundworks. A repair, widening or lowering does not necessarily affect the same ground volume as an earlier investigation. Existing utility plans describe infrastructure but do not in themselves constitute evidence concerning explosive ordnance.
04
Demolition followed by a new building
If a building is to be demolished and serviced differently, identify the interventions for both phases. Show old basements, new foundations and changed connection routes separately. The future building footprint alone does not show all planned ground interventions.
Project documents
Documents that establish the next step
Coordinate building and route plans
The trades involved need matching plan versions. If a utility line or building connection changes, communicate this before the works. A shared overview facilitates comparison with existing reports. However, it replaces neither the complete appendices nor the separate local procedural steps. For further use, retain the plan designation, date and cadastral parcel reference. Specialist planners can then compare a changed connection point with the documented investigation area. The complete report and its appendices remain accessible to those responsible for building construction and civil engineering.
Hand over results to the next contractor
The next participant receives the reports relevant to its working area with position and depth references. Limitations remain identifiable. Following clearance work, the clearance record with its actual clearance scope and results is also handed over for the building or site servicing areas addressed. An investigated building area is not extended to later site servicing without comparison. Outstanding interfaces between commissions are explicitly identified. Alongside the assessment, the areas, depths and limitations of findings are passed on. Identify inaccessible subareas as an open task. When work resumes, compare installations now planned and the current construction sequence with these results.
Construction sequence
Coordinate investigation and construction sections
Before awarding utility construction works
Check which connections and route sections the existing documents cover. Compare the planned commission with the documented areas. New chambers or different alignments remain visible. Agree the further steps needed before the affected groundworks.
At the transition from demolition to new construction
Old basements and utilities may affect ground volumes different from the new foundations. Show both phases traceably. Relate their respective results with their limitations. A shared construction objective does not extend an earlier partial report to all subsequent connections.
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
Plan investigation of building areas and utility routes
Assessment and current route plans
The historical aerial photograph analysis must be compared with the current building and route plans. If the alignment differs or working area expands, clarify whether the previous findings cover that area. Record which plan version underlies the enquiry and which changes are still expected.
Installations, interference and intervention depths
For the survey, existing utilities, metal installations, accessibility and the findings needed must be considered. A chamber or foundation may involve depths different from the connecting route. The suitable method and its limitations follow from the technical task, not from the term utility construction alone.
Requirements for private supervision during construction
A specialist supervision service during construction requires the technical and legal requirements to be met. The KampfmittelVO NRW distinguishes state tasks from limited exceptions for private activities. A short construction period or work on existing infrastructure does not extend those exceptions; the investigation procedure must be agreed beforehand.
Next steps
Bring construction and route plans to one consistent version
Record the groundworks
Compile buildings, utilities, chambers and connection excavations. For the initial project enquiry, discuss the construction task, areas, depths and next decision needed. Demolition, connections and temporary construction conditions are included alongside the new buildings. Known utilities and the respective current plan version are identified.
Mark new ground disturbance
Identify new groundworks in relation to existing installations. Check official information, aerial photograph analyses and investigation reports for plan version, spatial coverage, depth reference and outstanding questions concerning today’s task. The scope actually documented is decisive. Missing or conflicting information is identified with its relationship to the planned intervention.
Supplement historical information
The required state aerial imagery analysis is initiated through the municipal procedure provided locally. If the available findings need supplementation, further historical research is carried out for the specific question. Available aerial imagery, maps and records of use are professionally analysed and related to the present-day construction site. The findings feed into further investigation planning.
Add the procedural status
Identify applications, official communications and existing results. The specialist company selects the technically suitable approach using the investigation objective, grounds for suspicion, ground composition, interference and accessibility. Preliminary services and the permissible activity scope are clarified. Investigation areas and interfaces are coordinated with the construction sequence.
Investigate and assess results
Within the agreed and permissible scope, the defined areas or points are investigated using a suitable method. The data collected are recorded with location, depth reference and site conditions. Specialist personnel assess results and anomalies according to the investigation objective, method and interference. A measurement anomaly is not yet identified ordnance. Further clarification required and areas not adequately investigated are identified; local reporting procedures apply if ordnance is found.
Allocate tasks
Agree investigation and evidence handover for the individual construction commissions. Work performed and its technical assessment are documented in a report with the corresponding site and plan appendices. Methods, areas addressed, depth references and limitations of findings remain traceable. The client and designers compare that status with the next construction phase. Additional specialist works or official steps are identified before the interventions they concern.
Documentation
Pass on reports for buildings and utilities
Findings and their scope
The documentation should be relatable to the individual structural elements and route sections. If different companies work in succession, they need the plans and reports relevant to their area. Particularly at building connections and section boundaries, it should remain clear which investigation scope is documented and where further clarification is outstanding.
Project responsibilities
FONTANA-EOD documents which areas were investigated within the agreed commission and which limitations remain. If routes are moved or additional excavations become necessary, check those changes against the result. Passing a report to another contractor does not make it evidence for additional ground volumes.
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
Existing utilities are not investigation evidence
A utility plan helps describe existing infrastructure. It does not in itself answer the explosive ordnance question for new groundworks. An earlier investigation report is read separately with its appendices. Only comparison establishes whether the planned repair or extension is covered.
Understand investigation reports and their limitationsShared connections need clear boundaries
If several companies work at the same connection point, their respective working areas and results needed should be clear. Documents are passed on in full. Unresolved areas between them remain identified. Handing a report to a new contractor does not extend its spatial scope.
Understand the service scopeDesign and findings
Documents for the next construction decision
Historical evidence and the current design
Aerial photograph interpretation is related to the actual groundworks. Its purpose and geographical scope remain distinct from a technical investigation of the ground as it is today.
Understand aerial photograph assessment
Specialist reports for site management
The findings, their locations and limitations are handed over together. This makes clear to those carrying out the work which area has been investigated and which task remains outstanding.

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 construction projects and utility routes in Bielefeld
Are there different applications for buildings and utility routes in Bielefeld?
Yes. The municipal service portal provides separate application procedures for general construction projects and utility route construction. Select the option appropriate to the project and clarify interconnected or mixed tasks with the responsible authority.
Why must new groundworks be identifiable on the route plan?
The alignment of an existing utility does not automatically show the dimensions of a new trench, crossing or chamber. Therefore mark the proposed groundworks separately. Only then can it be checked whether earlier investigation results cover these areas.
Is building demolition not requiring a permit exempt from the explosive ordnance question?
Bielefeld’s service portal recommends an explosive ordnance assessment even for permit-exempt construction activities involving ground interventions. Show the planned groundworks and clarify the intended application procedure with the Feuerwehramt.
Can evidence for a building be used for all site servicing works?
Only insofar as its documented area and scope of findings match. Compare utility routes, excavations and depths with the report’s appendices. Connection works outside those boundaries require separate consideration.
What is required if possible ordnance is found?
Stop work in the affected area and keep your distance. Do not touch, move or further expose the object. Notify the police immediately on 110 and follow their instructions. Do not attempt to recover the object yourself.
Why should building and route plans have the same revision status?
So that connection points and the groundworks actually planned match. Differing versions may make spatial assignment of existing results more difficult. Changes are coordinated before execution.
Does a report for an old utility line cover lowering it?
This must be checked using the documented area, depth and limitations. Lowering may affect new ground volumes. The same utility alignment alone is not sufficient justification.
Which costs and lead times need clarification before commissioning?
The municipal application is free of charge; state explosive ordnance measures, preparatory and follow-up works by the construction participants, and a private specialist commission are allocated separately. For the private service, the investigation objective, areas, depths, methods, accessibility, assessment and documentation are particularly relevant. The fire service specifies an application lead time of no later than three months before construction starts; the service portal gives an approximate processing time of eight weeks. Coordinate the current procedural status and availability of the areas with the intended execution date.
Project enquiry
Plan buildings and site servicing in Bielefeld
Show buildings and utility routes in full
Send the current plans including connection excavations, chambers and crossings. Mark new groundworks in relation to existing utility routes. Add the property designation and, if necessary, an authorisation. For property acquired within the last twelve months, the Feuerwehramt refers to notarial evidence of the completed land register entry. For initial technical coordination, also identify known foundations, fill and areas not yet accessible.
Add earlier documents and the construction sequence
Include official communications and earlier reports with appendices. Identify the next construction section and contacts for the trades concerned. An industrial building with changed drainage requires plans of foundations, connection excavations, utility alignments and chambers with their proposed depths. Add existing assessments, reports and the respective local procedural status. State which groundworks are intended to start first and which investigation status the next trades need.

Have your project assessed
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.
FONTANA-EOD combines its Section 7 SprengG licence, specialists holding Section 20 SprengG certificates of competence, suitable survey and clearance methods, and traceable documentation. Send the site plan, depth of ground disturbance, construction phase and existing documents for an initial technical assessment.
