Ordnance assessment in Langenfeld for a specific construction project
You are assessing a property, but the future building's location and depth are not yet settled. The first question is then which ordnance documents already exist and what they establish. For a specific construction project, FONTANA-EOD helps developers, designers and site managers with specialist preparation in Langenfeld. A general property assessment and investigation of planned groundworks serve different purposes.
Read reports with their maps and limitations.
Identify open options and settled ground interventions.
Align further clarification with the actual project.
Assess the construction project
Assess construction intentions and existing findings together
An early property enquiry may concern different questions from investigation for a settled construction project. For your plans in Langenfeld, we review existing documents and identify what they establish. Once location, depth and construction method are defined, further specialist needs can be described specifically.
Project site
Connect the site with the specific construction task
Assign the Langenfeld enquiry and procedural status correctly
Langenfeld's current service portal describes how the legal and public order department forwards a necessary investigation application to the explosive ordnance disposal service at the Düsseldorf District Government. It specifies planned construction work involving substantial ground intervention for the procedure. Existing documents and your specific construction intentions are assigned traceably to this status. Langenfeld in the Rhineland is a town in the Mettmann district, Düsseldorf administrative district, in North Rhine-Westphalia. For projects in Richrath, Reusrath, Immigrath, Wiescheid or Berghausen, provide the precise project address and work areas affected. For projects outside the town, clarify the relevant municipal contact separately. Existing information and documents are assigned to the actual project location.
Local context
Clarify the purpose of the enquiry early
State the enquiry's purpose openly in the Langenfeld procedure
Langenfeld's service portal lists planned construction work involving substantial ground intervention as a prerequisite for the procedure. According to this description, applications intended for property valuation are not processed. An enquiry before a purchase decision should therefore not be presented as a settled construction project.
Compare existing documents with later plans
Existing documents can nevertheless be reviewed by specialists. The focus is their content: which area was considered, what investigation is documented and what limitations apply? Whether the findings are sufficient for later plans can be assessed only when their relevant ground interventions are known. This does not establish a purchase price or economic property value.
The account of the end of the war in Langenfeld published by the town archive describes air raids and artillery fire. The municipal administration moved from the central town hall to the Catholic school in Richrath at the time. US troops entered Langenfeld on 16 April 1945. For today's construction preparation, such local information on dates and uses is compared with wartime aerial photographs, historical addresses and records for the actual intervention area. The town history describes structural changes and expansion of transport connections since the post-war period. The local service portal refers to continuing possible hazards from Second World War ordnance. For a present-day project, historical findings are linked to the actual project area and later ground changes. Former uses, alterations and changed working areas are assessed using existing documents. The documented state of knowledge is then compared with the specific planned ground intervention. General town history does not evidence an individual investigation status.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For the commissioned activities, the relevant technical requirements and questions of permits, competence certification and responsibility are clarified. The actual planned service scope is decisive. A general company designation does not replace checking that the tasks and interfaces are described appropriately for the specific project.
Link occupational safety to the construction sequence
The risk assessment, working areas and communication must fit the planned activities. Explosive ordnance specialist works are coordinated with the other construction works. Operational organisation, traffic safety and other technical checks retain their own responsible parties. Joint coordination brings the information together and assigns tasks and decisions to the respective competent participants.
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.
Procedure at the site: Town of Langenfeld: ordnance investigation for construction work.
Planning and documentation: BFR KMR: principles of clearance planning · BFR KMR: geophysics · BFR KMR: documentation · North Rhine-Westphalia Ministry of the Interior: explosive legacy
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.
Private works are subject to the exceptions under the KampfmittelVO and the requirements of the official guidance. The exceptions concern, in particular, downhole detection as part of specialist foundation engineering and explosive ordnance clearance during construction under the conditions laid down by law. Private explosive ordnance clearance during construction requires that prior investigation using recognised explosive ordnance detection methods is not possible. A relevant factor is also the state explosive ordnance disposal service's assessment that there are no specific indications of ordnance contamination on the site concerned. All further spatial, technical and organisational requirements are clarified for the specific activity. The competent authorities decide on the official appointment.
Working together
Allocate tasks within the construction project
Client and operator
The client describes the project and provides the available project documents. The operator adds requirements relating to use, access and scheduling. The participants agree their respective tasks and decision-making responsibilities. A coordinating contact person brings the project information together. Before an appointment, it is recorded clearly which information is missing, who will obtain 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 explosive ordnance specialist company carries out the agreed permissible investigation and documentation scope. Authority requirements and decisions are clarified with the respective competent bodies. The documents needed for a specific procedure depend on the site and project. The technical report documents the specialist service performed, including areas, depths and limits of its conclusions. Its applicability to further groundworks is checked against the specific intervention.
The legal and public order department of the town of Langenfeld handles the local process. The town specifies construction work with substantial ground intervention for its procedure, excluding applications for property valuation. Any necessary ordnance investigation application is forwarded to the state explosive ordnance disposal service at the Düsseldorf District Government. Private specialist tasks and official decisions are coordinated within their respective permissible scope. The technical report documents the specialist service actually performed.
Investigation task
Which specialist task comes next?
Distinguish document review from investigation
A review assesses existing findings and identifiable gaps. An investigation needs a suitable question and spatial boundary. Before commissioning, define what finding is to be achieved at the present planning stage. A technical method is selected only from this specific task.
Assess historical documentsLink the commission to the local procedure
A private specialist commission is distinguished from state tasks under the North Rhine-Westphalia procedure. Specific legal prerequisites and necessary authorisations are checked before an agreement. The intended construction task remains decisive. A general question about property value does not establish early completion of an official investigation.
Compare investigation methodsProject types
Develop an assessable task from early construction intentions
State the purpose of the initial enquiry
State whether the initial aim is to understand existing documents or prepare groundworks already defined. This distinction affects the information needed for the next step. A purchase still under consideration is described as such. Specialist questions can then be addressed without pretending that firm plans already exist.
Identify the reason for the enquiry and documents already available. For early construction intentions, outstanding location and depth information remains identifiable. A review records which questions can be answered from the material available and which need further planning. If an investigation is to be prepared later, the ground interventions then defined are added. The agreed task and required findings thus remain assigned to the respective planning stage.
Coordinate the sequence and tasks
Show design options and their differences
Where several designs exist, describe their different ground interventions clearly. These may include a different location, additional structures or changed depths. Record which option is currently preferred and which remains open. This prevents a finding for one design being inadvertently passed on as a result for every possibility.
Alongside the building, show connections, retaining structures and the space needed for the work. For a basement or deeper individual structures, describe each volume of ground affected. State whether the options concern the same areas or additional ones. Specialist assessment addresses these specific differences. Before additional or preparatory ground interventions, clarify the necessary investigations and protective measures; specialist services still required remain identified with their scope.
Specialist services and investigation tasksObtain missing information specifically
A document list identifies which reports, maps or plan details are still needed. Also record who can provide this information. Further work can then address the decisive outstanding questions. A large collection of unsorted files does not replace traceable assignment to the property and intended construction task.
Assign older reports to their original purpose and associated plan. If only an extract is available, request the missing maps, legends or explanations from the issuer. A more recent response is assigned to the area it addresses. For further work, related documents are provided with their respective status. Specialist planners can then identify which information is usable for a design settled later and what finding must still be obtained.
Document findings and their limitationsPreparation
Prepare the scope and commission together
Historical preliminary assessment, technical investigation and specialist work during construction answer different project questions. The permissible private activity under the specific North Rhine-Westphalia procedure is clarified with the information objective and necessary authority involvement before an agreement.
Establish what needs to be known before commissioning the work
For the Langenfeld enquiry, record which construction intentions are already specific and which options remain open. Existing documents can be reviewed within their evidential scope. For a technical specialist task, describe the planned volumes of ground by location, depth and construction method. Identify missing information and its significance to the finding needed. The commissioned service has a specific scope and suitable result documents. Describe the actual purpose openly within the municipal procedure; property valuation is not presented as settled construction work.
Define the specialist taskCoordinate preparatory work with the investigation
For an agreed investigation, clarify actual access, existing utility information and coordination with other trades. Where several design options exist, it remains clear which area this preparation concerns. Necessary preparatory work depends on the method and site. Additional breaking out or other ground interventions to create survey access are prepared with specialist input and the responsible parties, rather than undertaken independently. A building location shown only provisionally is treated according to its planning status. Outstanding prerequisites are identified before fieldwork.
Clarify preparatory work in the programmeAgree a clear scope and schedule
The scope of private specialist work is agreed using the project documents, actual execution conditions and permissible activity. Necessary preparatory works, investigation, evaluation and documentation are described transparently. Costs and dates are related to these prerequisites and the required coordination. Changes to the construction plans are checked against the agreed contract before work is extended.
Discuss the scope and scheduleTasks at the site
Four questions to ask of existing documents
01
Which area is involved?
Check maps and location details together with the report. A present-day property description may differ from an older document. What matters is whether the areas considered can be assigned traceably. Unclear boundaries should be explicitly clarified before results are transferred to new plans.
02
What was actually investigated?
Distinguish historical analysis from a documented technical investigation. Read what task was undertaken and what finding was derived. A short summary without annexes may be insufficient for this review; request the complete report where possible.
03
Which construction options remain open?
If a building with or without a basement is under consideration, for example, describe the options separately. Planned depth is essential to specialist comparison. An assessment for one option cannot automatically be transferred to a different ground intervention.
04
What has not yet been clarified?
List missing maps, unclear depth information and outstanding indications briefly. Identify who can obtain each item of information. This list helps the next coordination step; it must not be mistaken for a positive or negative ordnance finding.
Project documents
Documents that establish the next step
Pass on an early assessment with its status
Document which records were available and which planning details were still provisional. Later participants must be able to recognise the limits of the assessment. An early review is not retrospectively described as an investigation of plans that have since changed. New findings and settled ground interventions are compared with the previous status.
Identify the versions actually used for the early review. If location or construction method changes later, describe this difference with the new plan. Any necessary addition addresses the outstanding task. Existing results retain their original question and limits. The continuing project file shows which knowledge was available at each decision and what further information was still needed.
Use complete results for construction planning
Reports are handed over together with their maps, annexes and limitations. The spatial reference is retained when ownership or designers change. The documented investigation scope is decisive for the planned work. An earlier commission or short results summary does not replace this comparison.
When documents are passed on later, include the associated plan version and outstanding options. Recipients receive the complete annexes to the specialist findings for their work area. After clearance work, the clearance record with its scope, results and remaining limits is also assigned to the area actually treated and applicable site plan. A newly planned ground intervention is compared with the areas and depths actually investigated. Older reference elevations are assigned to the ground surface applicable at the time. Changed ground or construction conditions are considered when checking applicability before further groundworks rely on these results.
Construction sequence
Coordinate investigation and construction sections
Organise the available information for the first discussion
Compile complete existing documents and a clear description of your construction intentions. Identify options still open. This establishes which questions can already be answered and which need further planning. Initial coordination then has a clear subject and avoids unfounded conclusions from incomplete information.
Add information specifically once the design is settled
Compare the firm plans with the scope previously described. Identify new areas, depths and construction methods. Further work addresses findings still missing. Before construction, site management receives results relating to this design and the remaining limitations.
Method selection
Select methods according to the task and survey conditions
Historical records and aerial photographs
Historical aerial photograph analysis and other older documents help locate the basis for suspected ordnance. Availability, interpretability and area boundaries considered determine the historical state of knowledge. The absence of a visible indication is not a present-day subsurface measurement. Existing analyses are linked to further results and the construction options currently known. This keeps clear which option extends beyond the area already considered or requires other depths. Historical assessment supports investigation planning but does not generally confirm every future building option still open.
Understand aerial photograph assessmentMagnetometric survey
Magnetic methods detect magnetic anomalies. Suitability is assessed for expected objects, ground conditions, interference and the volume requiring investigation. Fences, utilities and existing structures can affect interpretation. Signal strength alone does not identify explosive ordnance. Measurement, assessment and necessary further clarification are linked to the specialist task described. An open building option is considered according to its actual planning status. Magnetometry measures the magnetic field passively. The magnetic effect of the target object is decisive; electrical conductivity alone does not establish detectability by this method.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations may suit certain metallic targets and site conditions. Selection considers the finding required, accessible survey areas and interfering installations, rather than instrument availability alone. Results have a location reference and information on actual investigation conditions. Any necessary addition follows from specialist assessment and the specifically described construction task. Transient electromagnetic methods, or TDEM, evaluate the time-dependent electromagnetic response of conductive objects. The method is selected according to the investigation objective and actual survey conditions.
Understand electromagnetic surveyingGround-penetrating radar
Under suitable conditions, ground-penetrating radar can provide information about subsurface structures and reflections. Ground conditions, moisture and installations affect interpretability. A reflection is not automatically ordnance; an area without notable signals does not confirm any arbitrary depth. Specialist interpretation and limits are documented with the commission. An existing radar plan prepared for other tasks is checked for purpose and coverage before use as ordnance evidence. Once the building location is defined later, the area actually affected is compared with this coverage.
GPR and limitationsDeep-ground and downhole surveys
For deeper ground interventions, it may be necessary to assess whether a surface investigation can establish what is needed or whether another approach is required. Specific positions, depths, borehole layout and existing utilities then form part of preparation. While these details remain provisional, their status remains identifiable within the specialist task. Suitable investigation access is planned by specialists. A standard grid or general depth figure does not replace this task. Results remain tied to the areas actually investigated and the method used.
Prepare deep interventionsSurvey during construction
If a necessary advance investigation cannot be completed in full, specialists assess whether a planned approach accompanying construction is suitable. Investigation, interpretation and communication of findings are linked to specific construction work. Visual observation of excavated material alone does not replace a necessary survey. Site management receives the allocation of specialist work, new findings and unresolved areas within the planned sequence. An early document review for a general property enquiry does not replace this preparation. The task actually commissioned is described with the planned ground interventions and their prerequisites.
Agree the approach during constructionTechnical assessment
From existing knowledge to the investigation task
Read the historical assessment
The historical aerial photograph analysis must be considered with its spatial reference and stated uncertainties. It is not replaced by a general statement about property value. For construction planning, what matters is which findings exist for the planned intervention area and what further steps follow.
Official aerial photograph analysis is initiated under the local procedure through the enquiry provided for that purpose. The town specifies planned construction work with substantial ground intervention as a prerequisite. Review of existing documents records their original purpose. Outstanding historical questions and questions about an investigation actually performed remain separately described. Further work is coordinated with the current project and permissible commission scope.
Select the method with specialist input
A survey is planned according to the specific question and conditions on the site. Surfacing, existing installations and access may be relevant. Achievable investigation depths and findings are justified by specialists from these conditions and documented within the agreed scope. Selection particularly considers the investigation objective, intervention depth, ground structure, existing utilities, interfering objects and actual measurability. Necessary additions or a permissible investigation accompanying construction are agreed with their specific scope.
Describe the commission clearly
A clearance plan can bring together the necessary work and its sequence. In the specialist commission, describe the underlying plan version and questions still outstanding. This keeps traceable later what task was agreed and where a new decision is needed. The results documentation describes the work actually carried out.
A permissible specialist task accompanying construction is agreed with the areas to be addressed and existing findings. The work actually supervised, measurements and observations are assigned spatially. Limitations and follow-up investigations still needed remain identified. The technical report documents the service performed and its assessment. Applicability is compared with the specific ground intervention for later groundworks. Professional explosive ordnance clearance during construction includes the agreed technical specialist task; visual observation alone is not an equivalent substitute.
Next steps
How the enquiry develops with the plans
Compile findings
Collect existing analyses and reports in full. A single page from an older process may not be sufficient to understand its scope. Identify documents whose relationship to the property still needs checking and record their provenance. Existing documents are checked for currency, spatial relevance and gaps. Necessary research is undertaken where historical findings are missing. Any required official aerial photograph analysis is processed under the local procedure through the legal and public order department by the responsible state service. Clarify the stated prerequisites with the town.
Define the groundworks
Once construction intentions are settled, add the location, dimensions and planned depths. Consider connections and other structures alongside the building. Specialist planners can then compare specifically which parts existing findings cover and where clarification is missing. The suitable method is selected according to the information sought, intervention depth, ground structure, utilities, interfering objects and survey conditions. Permissible commissioning and outstanding execution prerequisites are agreed with those responsible.
Use the local procedure
Use the current forms from the municipal service portal. The sequence described there begins with aerial photograph analysis; where relevant indications arise, an ordnance investigation application follows. Forwarding to the explosive ordnance disposal service takes place through the legal and public order department.
Perform the agreed investigation
The survey or investigation during construction appointed under North Rhine-Westphalia's requirements is carried out in the agreed areas and points. Measurement data and observations receive traceable location and elevation references. Uninvestigated areas, restricted access and relevant interference are recorded.
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.
Compare results before construction
Check the documents received against the design now settled. If the excavation or foundations change afterwards, the finding must be related to this change again. Investigation of an earlier design does not automatically answer every question about later construction. Site management receives the report and associated plans with the specialist tasks still outstanding for its work area.
Documentation
Outstanding design decisions remain identifiable in the documentation
Findings and their scope
A specialist report should show what its findings are based on. This includes the areas considered, documented work and existing limitations. Maps and explanations accompany the report when passed to new designers. A shortened property description should not replace this information.
Project responsibilities
FONTANA-EOD undertakes the agreed permissible specialist tasks. The responsible town authority and state explosive ordnance disposal service make decisions under the local procedure. The BFR Kampfmittelräumung provide principles for planning and documentation. Their direct scope is federal properties; for other projects, they provide specialist guidance alongside local requirements.
Working approach
How FONTANA-EOD works
Document the agreed specialist service clearly
FONTANA-EOD undertakes the agreed specialist task for the Langenfeld project described and its current planning status. Assessment of existing documents and a technical investigation each have their respective scope. Accessible areas and results needed are agreed before the work begins. If plans or local conditions change, the scope is reviewed before the affected work proceeds. The report documents the work actually undertaken and its limits. Further planning can identify which findings are already usable and which questions about an open design option need separate clarification.
Discuss the investigation taskThe task before the equipment
Method selection starts with the information needed for the construction task specifically described. Specialist planning considers the volume of ground, existing results and actual investigation conditions. An available instrument or similar neighbouring development is not sufficient as the sole basis. Where options remain open, clarify what finding the agreed investigation is intended to support. Selection remains tied to this objective, rather than being inferred solely from a general property description.
Keep limitations visible
Inaccessible areas and areas with restricted interpretability are identified with their actual boundaries. Site management can assign outstanding tasks and necessary additions to them. A general total area figure does not replace this distinction. Planning and construction teams agree when a suitable investigation can be undertaken. Results for a defined part of the site are not implicitly transferred to other design options. The actual information needed for additional volumes of ground or different depths remains visible.
Clarify changes before intervening in the ground
If a previously open option is settled or a design changes in location, depth or construction method, the new version is compared with existing results before the affected work begins. Specialist planners receive a clear account of the difference from the previous investigation area. Their response and necessary additions are assigned to the current task. The same property address or a continuing project name does not, by itself, confirm an unchanged ground intervention.
Hand over the report and plan together
At handover, reports and associated plans are provided with the applicable planning version. A short overview can point to usable findings, limits and open design options. It does not replace the documented investigation scope. When site management or contractors change, the design underlying the specialist work actually performed remains traceable. Further planning can use applicable findings and specifically identify what is still needed for additional ground interventions. No statement about economic property value is derived from this.
Understand the results
Use technical statements for the next decision
A gap in the documents is not yet a finding
A missing map or unclear depth information initially identifies a need for clarification. It establishes neither contamination nor a property condition without anomalies. Identify the gap and the next step needed. Only suitable further work can provide the missing finding for the specific task.
Understand investigation reports and their limitationsA later use needs a specific ground intervention
A general construction intention permits several ways of building. Specialist assessment needs the groundworks actually planned and their scope. A changed use may therefore raise new planning questions without, by itself, determining a particular method. Existing knowledge is always compared with the applicable construction work.
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.

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 intentions and the procedure in Langenfeld
Can I use the municipal application solely for property valuation?
According to Langenfeld's service portal, applications for property valuation are not processed. The procedure described requires planned construction work involving substantial ground intervention. Clarify the purpose of your enquiry openly with the responsible authority.
What can be checked while the design remains open?
Existing reports can be reviewed for their findings, spatial reference and identifiable gaps. Identify construction options still open. Whether a result covers a later ground intervention can be assessed only against the applicable plans.
Is a seller's report sufficient for my construction plans?
The complete content and its relationship to your project are decisive. Check location, investigation scope, depths and limitations. Inclusion in sale documents alone does not establish whether the planned groundworks are covered.
Does aerial photograph analysis always lead to an on-site investigation?
The town describes the follow-up application where relevant indications arise. Further measures depend on the result and specific construction task. Necessary steps are agreed with the responsible authority using these findings.
Who should I notify about a suspicious find?
Stop the affected work and keep your distance. Do not touch, move or investigate the object yourself. Notify the police immediately on 110 from a safe distance, keep other people away and follow the authorities' instructions.
Is a list of missing documents already an ordnance finding?
No. It describes further information needed. A finding about the property follows only from suitable information and its relationship to the specific construction task.
How is an early assessment used after a new design?
Its basis and limits are compared with the new plans. Additional areas, depths or construction methods are explicitly identified for further work.
What cost factors matter for further specialist planning?
When designers change, complete reports with annexes, the associated plan version and an overview of outstanding questions are handed over. This keeps clear which findings actually exist for the project. The effort depends on usable previous documents, necessary preparation and access, the area or number and depth of investigation points, a suitable method, survey conditions, interpretation and documentation. Specialist services still required are offered within their permissible scope for the specific outstanding task.
Project enquiry
Prepare the first technical discussion
State the purpose of the enquiry
Distinguish document review, open construction intentions and settled groundworks. State the project address, plan version and any file reference. Include existing reports with maps and annexes. Explicitly identify missing documents. Where several designs exist, it remains clear which option is settled and which needs further planning. For a permissible application, use the town's current forms and required documents. The subsequent specialist enquiry then has a traceable relationship to the actual project.
Identify design options
Show differences between the ground interventions under consideration clearly. Identify the location and depth of each work area, necessary connections and preparatory exploratory openings. Communicate known utilities and access restrictions. Before preparatory or further ground interventions, clarify the investigations and protective measures needed. For area clearance or recovery tasks, agree the necessary scope and permissible commission with the responsible authority. Supplementary information is assigned to the original process with its respective status.

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.
