Ordnance investigation in Castrop-Rauxel: assign indications correctly
A large area is marked on a plan, while elsewhere there is an individual point. What matters is what these entries mean and which investigation has already been carried out for them. FONTANA-EOD supports clients, planning offices and site management in specialist preparation of their project in Castrop-Rauxel, turning different indications into a traceable task definition.
Compare the area described with the construction plans.
Read the marking together with its investigation status.
Distinguish investigations carried out from outstanding questions.
Assess the construction project
Read each marking with its source and result
Only together with its explanation does a point or area on a map convey specialist findings. For your project in Castrop-Rauxel, we assign existing documents to the current construction plans. Outstanding questions are clarified according to their actual processing status.
Project site
Connect the site with the specific construction task
Identify the Castrop-Rauxel specialist department and KBD Arnsberg
The town identifies the specialist ordnance department within Public Order as the point of contact for enquiries and registrations. Communication with the Arnsberg explosive ordnance disposal service also passes through this department. For your construction project, existing responses and results are related to current plans, and any further steps required are clarified through the appropriate procedure. Castrop-Rauxel is a town in the Recklinghausen district, in the administrative district of Münster, North Rhine-Westphalia. Identify the project address and work areas affected. The state KBD Arnsberg is also responsible for the administrative district of Münster. For projects outside the town, the relevant municipal point of contact is clarified separately. Local responsibility and assignment of existing documents follow the specific project location.
The overview of the Münster administrative district provides further local information for the regional context of your construction project.
Local context
A marking alone does not describe a completed procedure
Distinguish the meaning and origin of indications in Castrop-Rauxel
The town of Castrop-Rauxel explains different area-based and point-specific indications. It also distinguishes a location of suspected unexploded ordnance from an indication arising from detection. For a construction project, the meaning and origin of the marking are therefore important alongside its location.
Agree the permissible commission with the specialist department
Enquiries and applications pass through the town's specialist ordnance department within Public Order. The town also states that searching and checking are reserved for the explosive ordnance disposal service or companies specifically commissioned for this purpose. Clarify the permissible task and commission scope before arranging investigations or preparatory groundworks.
The town history describes destruction by air raids and artillery fire during the Second World War. For a present-day project, historical findings are linked with the actual project area and later ground changes. Reconstruction, changes in use and changed working areas are considered using existing documents. The further specialist task arising from this is compared with planned groundworks and the documented stage of work. General town history does not establish 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 Castrop-Rauxel: explosive ordnance – specialist department and procedure.
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 specialist ordnance department within Public Order at the town of Castrop-Rauxel receives local enquiries and registrations and communicates with the state explosive ordnance disposal service at the Arnsberg District Government. The town explains that searching and checking are reserved for the KBD or companies specifically commissioned for this purpose. For the specific procedure, the tasks required and those authorised to undertake them are clarified with the specialist department. Any permissible private specialist service is agreed with its own commission and documentation scope.
Investigation task
Which specialist task comes next?
Determine information needs from the source
Historical analysis and technical investigation provide different types of information. Further planning first clarifies which findings are available and which question remains outstanding. A suitable approach follows from this assessment and the planned groundworks. A symbol label alone does not determine an investigation method.
Assess historical documentsInvolve those responsible before further work
The town's specialist department coordinates the local procedure with the explosive ordnance disposal service. Further activities are agreed according to task and authorisation. A private specialist contribution has a clear, legally permissible scope. An existing map does not provide independent permission to investigate an anomalous location through groundworks.
Compare investigation methodsProject types
Bring different indications together clearly
Use the original map and explanation together
A forwarded image can lose its connection with the report and legend. Obtain the complete document with its date and attachments. The meaning of a marking is read from this context. A similar colour or symbol shape on another map does not justify transferring its specialist findings.
Assign the map revision used to its associated report and the current design. Where several parts of the site are involved, the basis of the marking remains identifiable for each. If an attachment is missing, request it specifically from the issuer. A document received later is recorded with its date and spatial scope. Specialist planning can then trace which information was already available for the next decision and which details are still needed.
Document findings and their limitationsRecord the stage of work for individual areas
A procedure can involve several applications, responses and investigations. Assign the affected area or location to each step. A later response supplements only the scope described in it. Other outstanding questions remain visible even if part of the work is already complete.
Use traceable area or location designations consistently. A response concerning an individual point is recorded with its location and the result described. If the construction task changes, identify the newly affected ground areas and volumes. Access and preparatory exploratory openings may also be important. Before each ground intervention, the investigations and protective measures required are clarified. The updated record identifies the specific question still needing an answer for the changed construction work.
Document findings and their limitationsSet out the current construction task alongside it
The location and depth of proposed groundworks are compared with existing findings. This identifies which question is relevant to the forthcoming work. An indication is not independently converted into a work instruction. Further steps are agreed with those responsible on the basis of the complete documents.
Alongside the building, show retaining works, connections and the working areas and volumes required. A relocated shaft or deeper foundations may affect different areas from the earlier plans. State depths with the relevant ground or elevation reference. Existing results are assigned to the task described in this way. Findings still required are agreed with those responsible and linked to the scope of work needed before the relevant construction activity.
Coordinate the sequence and tasksPreparation
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 Castrop-Rauxel commission, existing markings are brought together with their explanations and results. An area-based indication, a location of suspected unexploded ordnance and an indication arising from detection do not address the same specialist question. Identify the source, location and documented stage of work. The next permissible task is assessed with the town's specialist department and specialist planning: clarify documents, investigate an identified ground area and volume, or carry out further work on a finding already assessed. The commissioned service and results documents required receive a specific scope on this basis.
Define the specialist taskCoordinate preparatory work with the investigation
Before an agreed investigation, actual access, available utility information and coordination required with other trades are clarified. The preparatory work needed depends on the method, site and task as professionally assessed. A point marked on a plan does not yet describe a prepared measurement location. Additional breaking of the surface or other groundworks to provide investigation access are professionally agreed in advance with those responsible and are not undertaken independently. Existing indications remain identifiable with their actual status throughout this preparation.
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 for a plan with ordnance indications
01
Where does the entry come from?
Note which report the map comes from and its date. Historical analysis and technical measurement can provide different information. Without the legend and explanation, a point cannot reliably be assigned to an investigation completed or a task still outstanding.
02
What has already been investigated?
Look for the associated results report. A measure applied for is not the same as a service carried out. If the procedure was supplemented later, those documents also belong with it. A newer covering letter does not by itself replace every part of an older map.
03
What work is proposed?
Overlay the foundations, excavation, retaining works and other groundworks with their planned depths. An indication may be relevant to one part of construction without creating the same task for the entire property. Changes in construction method must form part of this comparison.
04
Which question remains outstanding?
State specifically what the available documents do not establish. Is the spatial boundary missing, the results report absent, or information about a proposed depth unavailable? These questions can be passed specifically to the competent authority and specialist planning rather than interpreting an unclear marking yourself.
Project documents
Documents that establish the next step
Connect the survey display with specialist assessment
A map from a technical investigation is read with the associated report. Only this context explains the task, conditions and limitations. An individual symbol is not interpreted as a particular object. Missing explanations are requested specifically before a construction decision relies on them.
Where investigation proceeds in sections, the areas actually investigated remain distinguishable. Record the access and measurement conditions under which they were investigated and where limitations remained. The specialist report relates its assessment to the data and findings recorded. A later addition is documented with its own scope. Related texts and attachments with the same revision status are used for comparison with the plans so that the agreed task and result achieved remain traceable.
Retain outstanding points in the handover of results
Documentation records what was actually investigated and which findings are still missing. A completed part of the procedure is assigned to its spatial scope. Site management receives the complete documents for its area. A summary clearance note must not conceal the limitations or outstanding questions stated in the report.
Also identify the document recipients and the work area for which the documents are needed. When a new report is handed over, it remains together with its plans and attachments. After clearance work has been carried out, the clearance record, including its scope, results and remaining limitations, is also assigned to the area actually treated and the associated plan attachments. Outstanding questions are passed on with the affected area or location and current plan revision. Those responsible for further commissioning can derive the next clarification needs from this. Changes to location, depth or construction method are compared with existing findings before the relevant work.
Construction sequence
Coordinate investigation and construction sections
Compile the complete record before an enquiry
Bring together maps, reports, file references and later responses. Identify which finding is unclear or which attachment is not yet available. Add the current groundworks plans. A focused question can then be assigned to the correct stage of work without mixing different indications.
Update the overall record after an addition
Assign the new finding to the area actually addressed. Earlier documents remain identifiable by date and purpose. Outstanding locations are not recorded as resolved merely because another procedure is complete. For construction, the current status is compared with the respective groundworks affected.
Method selection
Select methods according to the task and survey conditions
Historical records and aerial photographs
Historical aerial imagery analysis and other older documents help to place the basis for suspected ordnance in its spatial context. For a marking, it is checked whether it comes from historical imagery or a later investigation and what findings are documented for it. Availability, information value and area boundaries determine the state of historical knowledge. The absence of a visible finding is not a technical investigation of the ground as it is today. The analysis is linked with other results and the planned groundworks. A historical point location and a current measurement signal enter further assessment with their different origins identified.
Understand aerial photograph assessmentMagnetometric survey
Magnetometric methods detect magnetic anomalies. Suitability is assessed for expected objects, ground conditions, interference and the investigation area and volume required. Fences, utilities and existing structures can influence interpretation. Signal strength alone does not identify an object as ordnance. A mapped measurement signal is documented with its specialist assessment and any further investigation required. It is not equated with a historical indication merely because both are displayed as points. Magnetometry measures the magnetic field passively. What matters is the magnetic effect of the object being sought; electrical conductivity alone does not make it detectable by this method.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations may be suitable for certain metallic target objects and site conditions. Selection considers accessible survey areas, interfering installations and the information required; equipment availability alone is insufficient. Results include their location and the actual investigation conditions. Assessment determines whether a supplementary method or further clarification is needed. A point marking remains linked to the measurement result behind it and its meaning. Transient electromagnetic methods, or TDEM, evaluate the electromagnetic response of conductive objects over time. The method is selected according to the investigation objective and actual measurement conditions.
Understand electromagnetic surveyingGround-penetrating radar
Under suitable conditions, ground-penetrating radar can provide information on subsurface structures and reflections. Ground conditions, moisture and installations affect interpretability. A reflection is not automatically ordnance; an unremarkable area does not confirm conditions at any arbitrary depth. Specialist interpretation and limitations are documented with the investigation commission. The meaning of a marking on a radar plan is clarified using these documents. Before a report prepared for other purposes is used as ordnance evidence, its intended findings and actual coverage are checked.
GPR and limitationsDeep-ground and downhole surveys
For deeper groundworks, it may be necessary to check whether investigation from the surface can provide the information required or whether another approach is needed. Location, depth, borehole layout and existing utilities then form part of preparation. A point display without appropriate depth and results information does not replace this planning. The provision of suitable investigation access is also professionally prepared. A standard grid or blanket depth figure is insufficient. Results remain tied to the ground areas and volumes actually investigated and the method carried out.
Prepare deep interventionsSurvey during construction
If a necessary advance investigation cannot be completed in full, it is assessed whether a professionally planned approach during construction is suitable and permissible. Existing indications are assessed with the competent authority and specialist planning. Investigation, interpretation and communication of findings are linked to the specific construction work. Visual observation of excavated material alone does not replace a necessary ordnance survey. Site management needs an allocation of specialist work, new findings and unresolved areas within the work sequence. The meaning of an existing marking remains identifiable and is not replaced by a general description of supervision.
Agree the approach during constructionTechnical assessment
Bring together documents from different stages of work
Distinguish aerial imagery from fieldwork
A historical aerial photograph analysis contains findings from the imagery analysed and other sources consulted. It is not a record of field measurement already carried out. Its limitations and the requirements derived from it remain identifiable for further planning.
The origin of an indication is recorded in the project file with the findings actually available. For an enquiry, the complete analysis and specific construction task are provided together. If historical evidence is missing, the further work needed is clarified through the competent authority. A supplementary finding is assigned to the area addressed. Earlier documents remain identifiable with their own purpose and limitations even if a technical investigation is added later.
Read measurement and assessment together
A survey includes the area investigated, investigation objective and documented limitations. A survey plan without specialist assessment leaves the meaning of the results shown unresolved. In particular, a symbol must not independently be taken to represent a particular object. Suitable method selection considers the investigation objective, depth of groundworks, ground composition, existing utilities, interfering objects and actual measurability. Specialist assessment describes the findings achieved under these conditions and any additions that may be needed.
Define the next steps on specialist grounds
The clearance plan describes the tasks required and their sequence. The starting points are the specific findings and planned groundworks. General examples of procedures do not provide instructions for independent groundworks and do not replace coordination with the competent authority. The results documentation describes the work actually carried out.
A permissible investigation during construction is agreed with its specific task and the areas to be investigated. Observations and measurements are assigned to the work section actually supervised. Limitations and further investigations still required remain identified. The report records the specialist service carried out and its limitations. For later groundworks, it is checked whether the documented scope covers the proposed intervention. Professional explosive ordnance clearance during construction includes the agreed technical specialist task and its assessment; visual observation alone is not an equivalent substitute.
Next steps
From an unclear plan entry to an agreed construction task
Obtain original documents
Request the complete report and its attachments for the map extract. Transfer file references and plan revisions to the project documents. A forwarded screenshot may help with orientation, but does not replace the explanations behind the markings. Existing documents are checked for currency, spatial relevance and gaps. Where historical findings are missing, the research required is carried out. Any official aerial imagery analysis needed is processed by the responsible state service through the specialist department, and its results are assigned to present-day groundworks.
Assign responses
Identify which official response belongs to which area and application. Where there are several letters, outstanding and completed points should remain separately identifiable. Agreeing an appointment by telephone is not evidence that a necessary investigation has already been completed.
Agree the commission and preparation
Describe the specialist service actually commissioned and its prerequisites. These may include access, utility information and preparation of the investigation area. Whether and how preparatory work may be carried out must be clarified before it begins. A suitable method is selected according to the information sought, depth of groundworks, ground composition, utilities, interfering objects and measurement conditions. Permissible commissioning and outstanding prerequisites are agreed with those responsible.
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.
Use the result in construction planning
Give site management the complete document set for its work area. Identify remaining limitations and locations not yet investigated. If the plans change later, compare them again to establish whether existing results cover the changed task.
Documentation
Unresolved locations also belong in the handover
Findings and their scope
Documentation should identify which questions have been answered and which remain outstanding. A completed part of a procedure must not be presented as blanket completion for all areas. Keep maps and texts together so that those involved later can trace the spatial and specialist limitations of the result.
Project responsibilities
FONTANA-EOD carries out the agreed permissible specialist scope. Official duties and decisions are assigned to the respective competent authorities. The BFR Kampfmittelräumung provide planning and documentation principles that apply directly to federal property. Requirements of the local procedure and the specific commission must also be observed.
Working approach
How FONTANA-EOD works
Document the agreed specialist service clearly
FONTANA-EOD carries out the specialist task permissibly agreed on the basis of the identified indications and current construction design. Before work begins, the origin and processing status of documents are linked with the results required and accessible areas. If planning or site conditions change, the scope is reviewed before the affected work. The report documents the work actually carried out and its limitations. Site management can assign existing findings and specialist questions still outstanding. A marking alone is treated neither as a completed procedure nor as identified ordnance.
Discuss the investigation taskThe task before the equipment
Method selection begins with the question still outstanding for the area or location concerned. Specialist planning assesses existing findings and the meaning of their markings. Expected objects, ground conditions and actual site conditions help determine a suitable approach. Available equipment or a similarly marked neighbouring location is not sufficient as the sole basis for selection. The commission links selection to the planned groundworks and findings required.
Keep limitations visible
Inaccessible areas and areas with limited interpretability are identified with their specific boundaries. Site management can assign the tasks and prerequisites still required to them. A point marked there is recorded with its actual processing status. A general total-area figure does not replace this distinction. Planning and construction teams agree when a suitable investigation will become possible. The documentation continues to identify which findings are already available and which question remains outstanding for the next activity.
Clarify changes before intervening in the ground
A new location, additional depth or different construction method is compared with existing results before the affected work. Specialist planning receives the changed design and its relationship to previous area and point information. Its response and any additions required are assigned to the ground area and volume affected. The same property address or an unchanged marking number does not in itself establish that the current construction task matches the earlier investigation scope.
Hand over the report and plan together
At handover, the report, plan attachments and explanations of markings are provided together. A short overview can point to the findings, limitations and outstanding tasks important for the next activity. It does not replace the documented investigation scope. The origin and processing status of indications remain identifiable even when site management or contractors change. Someone joining the project can then trace the specific specialist question for the area or location, rather than deriving a statement about construction from a graphical marking alone.
Understand the results
Use technical statements for the next decision
Read an indication with the stage at which it arose
The source explains which information lies behind a marking. A finding from an analysis is not identical to a result from a later investigation. Keep these stages clearly distinguishable. Only then can an undocumented stage of work be clarified specifically and correctly assigned to the current construction task.
Understand investigation reports and their limitationsA newer letter does not automatically replace every earlier map
Check which area and findings the new response actually concerns. Unchanged parts and those still outstanding remain identifiable. The project documents are supplemented accordingly. Replacing all older documents as a blanket measure can obscure important limitations or tasks still outstanding.
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 assessmentSpecialist 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.

Process and documentationQuestions from planning
Questions about indications and investigation status
Does every point on a map mean a confirmed ordnance find?
No. Its meaning follows from the legend, explanation and underlying investigation. An indication or measurement anomaly must not be equated with an identified find without further specialist assessment.
Where should applications in Castrop-Rauxel be sent?
The specialist ordnance department within the town's Public Order service is responsible for enquiries. Agree there which documents and steps are required for the specific procedure.
Can I have an unresolved location exposed myself in advance?
Do not arrange independent groundworks to investigate such a location. The approach and those authorised to undertake it must be clarified with the competent authority. A marking on a plan is not a work instruction for civil engineering contractors.
Is an investigation of part of the site sufficient for the entire construction project?
Only insofar as the documented scope covers the groundworks actually planned. Compare area, depth, investigation objective and limitations. Further needs are justified on specialist grounds from this comparison rather than derived solely from a shared project name.
What should I do about a suspicious object?
Stop the affected work and do not move or touch the object. Keep your distance and keep other people away. Notify the fire service immediately by calling 112 or the police on 110 and follow their instructions.
What helps if only a screenshot of a map is available?
Request the complete report with the original map, legend and attachments. A screenshot alone cannot reliably convey the specialist context and scope of findings.
How is a later response added to the record?
With its date and an unambiguous assignment to the area or location affected. Only the findings actually addressed in it are updated accordingly.
Which cost factors depend on the proposed groundworks?
The proposed groundworks determine which findings are needed for construction. Location, depth and construction method are therefore compared with the complete existing documents. The effort depends on usable previous documents, preparatory work and access required, the area or number and depth of investigation points, a suitable method, measurement conditions, and interpretation and documentation. The town explains possible costs of preparatory, accompanying and follow-up work. Their specific scope is agreed for the individual case; a private quotation relates to the specialist scope permissibly commissioned.
Project enquiry
Prepare the first technical discussion
Send the complete context
Include the report, map, legend and associated responses together. State the project address, plan revision and any file reference. Describe which question the next stage of work is intended to answer. Where several parts of the site are involved, their designations are used consistently. Missing attachments and responses still outstanding remain identifiable as specific points. Existing documents can then be assigned to the appropriate specialist step. The handover distinguishes work already carried out from further measures merely intended.
Describe the outstanding question
Identify unclear markings or missing results and show the proposed groundworks affected. Include the current groundworks plans with areas, depths and working areas and volumes required. Communicate known utilities and restrictions on access. Before preparatory or further groundworks, the investigations and protective measures required are clarified. For area clearance or recovery tasks, the scope required and permissible commissioning are agreed with the competent authority. Supplementary details are assigned to the original question with their respective revision 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.
