Project site
Connect the site with the specific construction task
Address Bremen and Bremerhaven on a site-specific basis
The state of the Free Hanseatic City of Bremen comprises the two municipalities of Bremen and Bremerhaven. Bremen Police provides preliminary clarification for both. Further work requires the exact project location and proposed works. For projects at several sites, reports and decisions remain assigned separately. For adjoining project sites in Lower Saxony, identify the municipality and state separately; the relevant responsibilities and procedures apply there.
Information on explosive ordnance surveying in Bremerhaven supports preparation of your project enquiry. Documents and planned ground disturbance on the respective property are decisive.
The existing overviews for Bremen City lead to the associated local information. Select the area of your construction project; the specific municipality and properties affected remain decisive for the enquiry.
Local context
Historical evidence and preliminary clarification at the project location
Preliminary clarification for both municipalities
Bremen Police provides an application for preliminary clarification for construction projects in Bremen and Bremerhaven. It is responsible for classifying areas with suspected ordnance. Additional private investigations are documented with their own commission and investigation objective; the official classification is made by Bremen Police.
Bremen State Archive describes an air raid on the night of 18–19 August 1944 that caused substantial damage to the Ostertorwache prison. The historical information about the Ostertorwache is compared geographically with contemporary plans and today’s project area where suitable records are available. The present investigation requires specific property records. Bremen Police identifies wartime aerial photographs, archives and records of finds as evidence used in its reconnaissance. Individual historical events are therefore compared with the findings for the respective project area.
Records and initial coordination
The information from Bremen Police’s explosive ordnance disposal service explains the procedure for both municipalities. Details of the property, construction project and proposed earthworks, together with informative location records, should be assembled early. Before planning technical measures, establish which official response is already available.
Scope of services and local requirements
We review your existing records and discuss the investigation and documentation needed. Surveying and clearance must take account of Bremen’s requirements, the necessary approval or commissioning, and the permitted scope of activities.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For commissioned activities in Germany, clarify the applicable technical requirements, permits, competence certificates and responsibilities. The actual proposed scope of services is decisive. When searching for found ammunition, consider the scope of section 1b of the German Explosives Act. Relevant commercial activities are assessed against the company permit under section 7 and the competence of responsible individuals under section 20. Activities in Bremen must additionally meet the prerequisites and official requirements provided for in state law.
Link occupational safety to the construction sequence
The risk assessment, work areas and communication must suit the planned activities. Specialist explosive ordnance work is coordinated with other construction work. Operational organisation, site and traffic safety, and other technical specialist assessments retain their own responsible parties. Joint coordination brings the necessary information and respective responsible people together.
Use technical findings correctly
A measurement anomaly first requires specialist assessment; its appearance alone does not identify it as explosive ordnance. If an object is genuinely suspected to be ordnance, the prescribed reporting procedures and the measures set by the responsible authorities apply. Investigation reports specify the work completed and its limitations, so that results are not extended to unexamined areas or later design changes.
Local procedures: Bremen Police: explosive ordnance disposal service and preliminary clarification · Bremen: Act on the Prevention of Damage Caused by Explosive Ordnance, particularly sections 1, 5 and 6.
The BFR Ordnance Clearance guidance on documentation describes traceable reporting of results within its federal scope. It provides technical guidance for other projects. In Bremen, local requirements and official responsibilities are clarified through the state procedure.
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 in Germany 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 project owner describes the project and provides the existing project records. The operator adds requirements for use, access and timing. Project participants agree their respective tasks and decision responsibilities. Before commissioning, it is clearly recorded which information is missing, who obtains it and which decision the result is intended to support.
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 ordnance specialist contractor carries out the agreed investigation and documentation scope. Official requirements and decisions are clarified with the responsible authorities. The records needed for a specific procedure depend on the location and project. The technical report documents the specialist work performed, including areas, depths and limitations. Its applicability to further groundworks is checked against the specific intervention.
Bremen Police performs the tasks under Bremen’s Explosive Ordnance Act unless the Act provides otherwise. Its explosive ordnance disposal service is the contact for both municipalities. The authority determines the necessary surveying scope, maintains the register of suitable contractors and decides on clearance of the ground. Special official commissioning rules apply to handling explosive ordnance. Building control and other specialist authorities conduct their respective procedures. Coordination identifies the authority actually responsible for each outstanding decision at the project location.
Investigation task
Which specialist task comes next?
Review official statements and supporting evidence
Technical preparation requires preliminary clarification or existing statements and the specific groundworks. Additional historical records can explain the task. They do not replace official classification. Define the next commission from the scope required for the property and the actual working conditions.
Assess historical documentsDefine a suitable technical investigation
Area, depth, possible interference and access determine technical preparation. An investigation is not selected solely because a property is described as a port, residential or commercial site. The commission specifies the results needed and coordination between tasks. Areas that cannot yet be investigated remain identifiable so a later construction phase does not rely on an incomplete assumption.
Compare investigation methodsBremen and Bremerhaven
Construction in urban areas, ports and commercial sites
An urban property involves different access and construction phases from a port terminal. In both cases, any indications of explosive ordnance must be clarified for the specific area.
Bremen City: neighbourhoods, the Weser and commercial areas
In urban infill development, new excavations and utility works meet existing buildings and dense infrastructure. Along the Weser and in port, industrial and freight areas, operational traffic routes and larger paved areas are additional factors. Investigation limits and construction phases must accommodate these uses.
For several construction phases, plot the corresponding drawing revisions and areas covered by results together. Record which investigation took place before demolition and which structures were still present at that time. Determine the findings needed for new working spaces, connections or deeper foundations individually. Property boundaries may differ from the area actually investigated. Request missing report appendices before relying on older results. The project file records which current construction phase was compared with which earlier evidence and which task remains outstanding.
Bremerhaven: port, shipyards and logistics
Terminal areas, maritime commercial sites and former shipyards may have records from different periods of use and construction. Dike, waterfront or logistics projects require consideration of intervention depth, access, operations and, where relevant, water-related conditions. Describing an area as a port or shipyard does not establish whether a specific suspicion of explosive ordnance exists or has already been resolved.
For an investigation section on an operating terminal or commercial site, agree the available working areas with the operator. Identify vehicle movements, temporarily occupied areas and access needed for operations. Technical planning assesses their influence on the investigation and defines the necessary conditions. If occupation changes during the work, document the scope actually achieved. A later continuation receives its own geographical reference. Site management can then relate the results of individual sections to the planned follow-on works.
Distinguish waterfront works from works in a body of water
A ground intervention behind a waterfront retaining structure differs from works in a body of water. The position and scope must therefore be described clearly. Water-related tasks require separate clarification of technical services, responsibilities and conditions; a land-based investigation does not automatically cover an intervention in the water.
For a waterfront structure, describe land-based excavations, the retaining structure and any affected areas of water separately. A site plan alone does not show every depth or working space required. Additional sections make the planned geometry and the relevant ground or bed elevation traceable. Agree the technical service required, its execution conditions and responsible parties for each area. Water-related tasks receive a separate service description. Compare a change in construction method with the existing investigation scope before the additional intervention.
Project types
Plan the next groundworks under actual conditions
Prepare urban excavations
For alteration or new construction, describe the excavation actually needed, working spaces and connections together. Existing buildings and utility lines can affect access and investigation. Include these conditions in coordination early. A report for a neighbouring area is not used solely because it is nearby. The specific task remains tied to your design and the available findings for it.
Provide specialist supervision of excavation
Provide working areas while operations continue
Traffic routes on commercial and logistics sites may still be needed during preparation. Identify these uses and the available time windows. Agree the investigation commission with those responsible for operations. Organisational permission to access an area is a different task from the technical ordnance assessment. Both prerequisites must be demonstrably in place for each stage of work.
Coordinate the sequence and tasks
Record foundations and connections together
Foundations, piles and utility connections can involve different depths and areas. Include outside areas beyond the building footprint. Consider existing reports for every intervention required. Keep additional working spaces visible in the design. A general description of the construction property does not replace defining the actual investigation commission.
Understand downhole surveysServices in the city-state
Which investigation does your construction project need?
Which of the following services may be suitable depends on the suspected ordnance, ground conditions, official classification and commission. Not every project needs all methods.
Historical aerial photograph analysis and assessment of suspected ordnance
Aerial photographs, former uses and existing statements help establish which indications relate to the planned construction area. For port or industrial sites, this also involves changed boundaries, fill and former installations. Additional private research is documented separately from official preliminary clarification. For industrial projects the history of use, intervention area and operating conditions are considered together.
Review historical evidenceSurface survey
Suitable geophysical methods may be considered for accessible construction areas, traffic areas and development sites. Reinforcement, utility lines, scrap and ongoing operations can affect measurements. Measurement data show anomalies that require specialist interpretation and, where necessary, further investigation.
Surface survey methodsDeep-ground and downhole surveys
Pile foundations, sheet piles and deeper excavations require consideration of the ground actually affected. A surface investigation does not establish findings to any arbitrary depth. Position, planned depth and construction method form the basis for technical preparation.
Prepare deeper ground interventionsArea clearance
Suspected points or contaminated sections requiring work need an agreed clearance scope. Before starting, agree the clearance objective, access required, protective measures and documentation. The results relate to the areas and depths actually investigated and worked.
Determine the clearance scopeOrdnance specialist supervision of groundworks
Investigation before excavation may be restricted on existing traffic and operating areas. If supervision during construction is technically and legally suitable, define work sections, responsibilities and reporting procedures before starting. It is not a general substitute for necessary preliminary investigation.
Coordinate excavation supervisionExplosive ordnance finds and official responsibilities
The responsible authorities are involved when a find is confirmed. Private activities depend on approval, permits, the commission and official requirements. Bremen Police carries out ordnance disposal under state law itself or arranges it. In the statutory sense, this includes defusing, destruction, recovery and transport. The prerequisites for private specialist works are clarified against the specific activity commissioned.
Ordnance recovery and responsibilitiesProject documents
Documents that establish the next step
Organise records by their function
Site plans, official statements and technical reports answer different questions. Record each document’s revision and references. Request missing appendices before deriving findings for construction. A common overview refers to the complete documents and shows which step remains outstanding before the next intervention. The project file links the commissioned measurement data, survey results and interpretation of findings to the full report and its drawings. After clearance work, assign the clearance record, with its scope, results and remaining limitations, to the area actually worked.
Pass on changes before earthworks
Compare new foundation positions or changed depths with existing results. Provide the change to the responsible design team in good time. Where official requirements are affected, resume that coordination too. Retain the existing report within its original scope; do not silently extend it to the new design.
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.
Transient electromagnetic methods, or TDEM, interpret the electromagnetic response of conductive objects over time. Suitability and limitations are assessed against the investigation objective and actual measurement conditions.
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 constructionPlanning and records
Records, operating procedures and results documentation
Must an access route remain usable, or will work continue alongside the investigation? Include these details in planning early. They help coordinate work sections and access required.
Provide preliminary clarification, the site plan and earlier investigations
Preliminary clarification or existing statements, a site plan, plot details, intervention depths and information on former uses are helpful. Include existing measurement reports, details of utility lines and existing structures, and the desired time frame.
Coordinate operations and works
On industrial and logistics sites, agree the required access and work sections with site management and those responsible for operations. Restrictions must be identifiable before work starts. Time and effort depend on actual conditions and the measures required.
Document areas covered and limitations
Drawings and records should show which area was covered by which method and where limitations remain. Agree the commissioned scope of evidence beforehand. For new or deeper interventions, check whether existing results remain sufficient.
Documentation and limits of conclusionsTechnical assessment
Check evidence, conditions and limitations of results
Read existing findings
Compare preliminary clarification and existing specialist reports with the current construction design. Official statements, historical indications and technical investigation results remain distinguishable. A short note without its appendices is often insufficient to identify geographical coverage. Identify missing records and request them specifically before further use.
Describing survey conditions
Describe paved surfaces, installations and access required for the intended measurement date. These conditions can influence the suitable approach. Include necessary preparatory works and their own prerequisites in coordination. Later use of a completed area does not automatically describe its condition during investigation.
Record the actual condition of the working area for measurements. This includes existing paved surfaces, accessible survey routes and relevant metal installations. Moving vehicles or changed storage arrangements may create different conditions from an earlier investigation. Technical planning determines how such effects are considered during execution and interpretation. Describe necessary preparatory works with their own ground interventions and carry them out only once the investigation and protective prerequisites for them have been clarified. Measurement records and drawings show the conditions under which individual data were collected.
Relate results to the commission
A report identifies the task actually performed and its limitations. Compare the construction design with the documented area and depth. When changes occur, determine which findings still apply and where additional work is needed. Commissioned services remain separate from decisions of the responsible authority.
Next steps
The next steps for your project
Describe the project area and interventions
Assemble property details, the site plan and specific groundworks, including depths and working spaces. Include preparatory interventions so the findings needed first can be coordinated in time. For initial contact, add the project address, plots and a contact person. We review existing reports and complete drawings for revision, geographical coverage, investigation scope and missing information.
Record the progress of preliminary clarification
State whether an official statement is already available. Provide complete records and relevant requirements. Clarify outstanding information before commissioning the investigation rather than substituting assumptions about neighbouring properties. If historical findings are needed for additionally commissioned technical planning, we carry out the necessary source research and aerial photograph analysis. Relate the results to today’s intervention area. Coordinate official preliminary clarification and the records it requires with Bremen Police.
Agree the scope of services and access
Describe the results needed and working conditions. Site management, technical planners and, where relevant, those responsible for operations coordinate the works. Their respective responsibilities and necessary official steps remain identifiable. Method selection considers the investigation objective, expected objects, ground conditions, interference and accessible areas. Clarify necessary official requirements and the permitted scope of activities before work starts.
Perform the agreed investigation
Surveying or investigation during construction commissioned under Bremen’s requirements is carried out on the agreed areas and points. Measurement data and observations receive traceable positional and elevation references. Record areas not investigated, restricted access and relevant interference.
Assess survey data and findings
The collected data and findings are evaluated against the investigation objective. The technical assessment considers interference, the areas reached and remaining limits of the conclusions. It establishes which further investigation or work is needed for the planned groundworks.
Bring the report and plan appendices together
The report and plan attachments document the specialist works performed and their assessment. Worked areas, investigation depths, the relevant ground surface and limitations remain assigned. Reused older results and newly investigated areas are recorded distinctly. The agreed recipients receive the related documents together.
Coordinate results and further tasks
Hand over reports with their appendices and the drawing revision used. Identify outstanding areas and limitations. The technical and official prerequisites required for the next groundworks must be in place. The client, design team and site management determine the next technical tasks from the results. For construction measures under section 5 of the state Act, obtain the necessary clearance of the ground from the responsible authority; the authority also decides on exceptions.
Construction sequence
Coordinate investigation and construction sections
Before the first ground intervention
Assemble property details, the site plan and a description of the earthworks. Clarify the progress of official preliminary clarification and include existing reports. Agree the prerequisites for the first proposed works. These may already include demolition or site establishment where they affect the ground.
Between investigation and construction
Assign the results documentation to the current design and pass it on through the agreed channels. Technical findings and the required official decision remain distinguishable. Before work starts, site management must be able to identify which prerequisites for its intervention are fulfilled. An overall project status must not conceal outstanding areas.
Documentation
Identify the investigation, results and official decision
Findings and their scope
The technical documentation describes the commissioned investigation, including area, method and limitations. It is assigned to the current construction project. Any outstanding section or changed depth must remain identifiable when records are handed over to other parties.
Project responsibilities
Bremen’s Explosive Ordnance Act connects surveying within the scope determined by the authority with official clearance of the ground. Under section 5, the suitable commissioned contractor reports the start of work and the survey results to the responsible authority. The private investigation report documents the specialist work; the responsible authority grants clearance of the ground. Coordinate the records and procedural steps required for the specific project accordingly.
Working approach
How FONTANA-EOD works
Document the agreed specialist service clearly
We assess the planned groundworks against the available documents and their design revision. Before attending site, we agree with you what needs to be investigated, which areas are accessible and what findings are required. If the design or site conditions change, we check whether the agreed scope remains appropriate. The report states what was actually investigated and the limits of the findings. This allows designers and site management to see which findings they can use and where questions remain.
Discuss the investigation taskThe task before the equipment
We first establish the investigation objective: which question must it answer? We then select a technically suitable method. The availability of a particular device or experience on a similar neighbouring site is not enough to justify the choice of method on its own.
Keep limitations visible
Inaccessible areas and limited conclusions are identified. They do not disappear into a total area figure. Designers and site management can then decide specifically which areas still need attention and when a suitable survey becomes possible.
Clarify changes before intervening in the ground
A new location, additional depth or different construction method is compared with previous results. A familiar project name does not replace this comparison. Feedback is provided before the affected work so that an outstanding question can be included in the sequence.
Hand over the report and plan together
The technical conclusion remains connected to its location references and appendices. A brief summary helps orientation but does not replace the documented survey scope. This basis is retained even if site management or contractors change.
Understand the results
Use technical statements for the next decision
Identify the specialist report and official decision
A private report documents the commissioned investigation and its results. Official decisions required in Bremen depend on local regulations and the specific case. Pass each document to the next parties with its function identified. Outstanding technical or official steps before construction then remain traceable.
Understand investigation reports and their limitationsDocument the commission and its limitations
The results handover specifies the area investigated, task, methods and limitations. Areas not covered are also identifiable. Compare changes in position or depth with that scope. A new intervention may need additional findings even where a report already exists for the same site.
Understand the service scopeDesign and findings

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.

Process and documentationQuestions from planning
Questions about preparation in the state of Bremen
Does Bremen’s preliminary clarification procedure also apply to Bremerhaven?
The procedure provided by Bremen Police covers projects in both municipalities. The enquiry requires the exact property location and the proposed works. Findings for one site are not extended to other areas.
Which documents are needed for an initial enquiry?
A site plan, plot details, a description and depth of the groundworks, and existing statements and reports are helpful. Also identify installations, access and the planned construction sequence. Keep missing information explicitly identifiable.
Who decides whether the ground is cleared for construction?
The private report documents the commissioned investigation scope and its results. The responsible authority grants the clearance of the ground required under section 5 of Bremen’s Explosive Ordnance Act. Coordination depends on the project and the required surveying scope.
Does every project require investigation using all methods?
No. The need depends on the specific area, planned interventions, existing findings and applicable requirements. Technical method selection also considers actual conditions and the findings needed.
What should you do if a suspicious object is found?
Stop the affected work, do not touch or move the object, and move away. Keep other people away and notify the police immediately on 110. Follow official instructions and do not attempt your own investigation or transport.
What role does private historical research play?
Additional private research can provide information about the area. Its sources, geographical relevance and limitations are documented. Official preliminary clarification and the decisions required for the specific project take place through the responsible Bremen Police procedure.
Does a land-based investigation also cover works in a body of water?
Not automatically. The position, depth and conditions of the intervention in the water are described separately. The technical services and responsibilities required must be clarified independently.
Which factors affect costs and scheduling?
Alongside area and depth, the available records, progress of official coordination and access are important. Installations and ongoing operations may also affect the work. A precise task description supports planning. The methods, necessary preparatory works and agreed documentation scope also matter. Under section 8 of Bremen’s Explosive Ordnance Act, the responsible party bears the costs of preparatory works, surveying, exposing objects and reinstatement; the state bears the costs of ordnance disposal as defined in the Act.
