Ordnance investigation in Bad Oeynhausen before groundworks
The location and depth of an excavation, foundation or borehole are planned. In Bad Oeynhausen, protection of medicinal springs may also need to be considered. FONTANA-EOD supports ordnance investigation for the proposed groundworks. Any other requirements affecting the project must be clarified with the authorities responsible for them.
Show the groundworks area and affected structures on the plan.
Clarify ordnance and medicinal spring protection separately.
Assign results to the relevant commission and area.
Assess the construction project
Coordinate the ordnance task with other requirements
For groundworks in Bad Oeynhausen, the proposed works must be understandable in terms of their location and depth. We define the agreed ordnance task on the basis of these plans. Questions of medicinal spring protection are clarified separately with the competent authorities for the specific area affected.
Project site
Connect the site with the specific construction task
Bring together the separate responsibilities in Bad Oeynhausen
For ordnance matters, the town identifies its local public order authority and the explosive ordnance disposal service of the Arnsberg District Government. The medicinal spring protection ordinance has its own framework of responsibilities for the water authorities. For your project, the respective requirements are coordinated according to the specific location and activity; the results retain their own subject of assessment. For the ordnance question, the specific project location in Bad Oeynhausen is identified, for example Dehme, Eidinghausen, Lohe, Rehme, Volmerdingsen, Werste or Wulferdingsen. For water law matters, the medicinal spring protection ordinance distinguishes the generally responsible districts of Minden-Lübbecke or Herford from specific responsibilities of the Detmold District Government. Which authority is involved depends on the location and project; the town's public order authority remains the local point of reference for ordnance matters.
The overview of the Detmold administrative district provides further local information for the regional context of your construction project.
Local context
Two assessment tasks for the same groundworks
Clarify ordnance matters through the responsible local authorities
The town of Bad Oeynhausen describes itself as the local public order authority for ordnance matters and identifies support from the explosive ordnance disposal service of the Arnsberg District Government. For specialist preparation, existing findings are compared with the planned construction task. A water law document does not answer this ordnance question. For local coordination, the property, affected structures and planned depths are described together. A borehole position for investigation also remains visible on the site plan as a ground intervention in its own right. Existing ordnance information is compared with the current design before being used for a new construction phase. The project status also identifies the decision still outstanding and the point of contact responsible for it.
The town chronicle describes bombing raids during the Second World War and, for 1945, the evacuation of the town centre followed by the arrival of the headquarters of the British Army of the Rhine. In the historical assessment of a construction project, these contexts of use and war are linked with specific property records, historical imagery and later alterations. This does not produce a present-day map of suspected ordnance for the entire town. What remains decisive is the documented connection with the planned groundworks area.
Consider medicinal spring protection by specific location and activity
The medicinal spring protection area ordinance of 13 April 2023 establishes different protection zones and their boundaries. The associated maps and the provisions applying to the specific area are decisive. An address in Bad Oeynhausen alone is therefore insufficient to determine a particular requirement or permissible depth of groundworks for a project. The ordinance distinguishes quantitative protection zones A and B from qualitative zones II and III. The associated maps serve different purposes: the overview provides orientation; the definitive protection area maps must be consulted for the precise boundaries. Where a boundary area is unclear, the location and activity are clarified with the competent authority before a construction requirement is derived from them.
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
Risk assessment, work areas and communication must suit the proposed activities. Ordnance specialist works are coordinated with the other construction activities. Operational organisation, traffic safety and other specialist technical inspections retain their own responsible parties. Joint coordination brings the information together without equating the different tasks.
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 Bad Oeynhausen: explosive ordnance disposal · Detmold District Government: Bad Oeynhausen medicinal spring protection area ordinance of 13 April 2023, official gazette no. 17.
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.
For private activities in North Rhine-Westphalia, the specific requirements of the exceptions under the KampfmittelVO and the official guidance must be observed. Technical suitability alone does not establish that a private commission is permissible. The information held by the authorities and the authorisations required for the activity are checked before an agreement is made.
Working together
Distinguish the tasks of client, designers and specialist contractor
Client and operator
The client describes the project and provides the existing project documents. The operator adds the requirements for use, access and timing. A coordinating contact agrees the assigned tasks with those responsible. Before commissioning, a clear record is made of which information is missing, who will obtain it and which decision the results are intended to inform.
Planning and construction management
The specialist designers describe areas, depths, construction methods and changes. Site management coordinates the planned sequence with the construction contractors and agreed specialist works. Results are assigned to the respective intervention. A technical plan change is communicated early enough for its effect on the survey task to be assessed before construction. Organisational construction stage boundaries remain distinguishable from technical survey boundaries.
Specialist company and competent bodies
The private explosive ordnance specialist carries out the agreed investigation and documentation scope. Official requirements and decisions are clarified with the competent authorities concerned. The documents needed for a particular procedure depend on the location and project. The technical report describes the specialist service performed; its conclusions are not presented unchecked as general authorisation for further groundworks or as an authority's decision.
Investigation task
Which specialist task comes next?
Define the investigation objective and groundworks together
The ordnance information required follows from existing findings and the planned project. If the investigation itself requires ground intervention, this forms part of preparation. The method and scope are assessed on specialist grounds. Any further requirements for the specific work must still be clarified with those responsible for them.
Assess historical documentsDistinguish the permissible specialist commission from other decisions
For private work in North Rhine-Westphalia, the specific legal conditions and authorisations required are checked. Other requirements may also affect the project. These are not replaced by the specialist commission. The agreed scope and decisions still outstanding must be understandable before the affected work is carried out.
Compare investigation methodsProject types
Address different requirements using the same plans
Show all proposed groundworks clearly
The plans show the main excavation, foundations and additional groundworks outside the main building footprint. Any proposed investigation involving ground intervention is also described with its scope. This allows everyone involved to consider the same specific task. A general property address does not replace the spatial allocation of individual work activities.
Provide specialist supervision of excavation
Document outstanding requirements separately
Record which questions concerning the ordnance task and which concerning other matters still need clarification. Existing decisions are recorded with their subject matter. A positive finding on one specialist question is not treated as resolving all other tasks. This keeps the project status understandable for planning and construction.
Document findings and their limitationsUse a common plan revision
The different specialist authorities should be able to identify which revision your information refers to. Changes in location, depth and construction method are clearly identified. Make sure additions reach those affected. Different records must not inadvertently describe different groundworks as though each represented the current plans.
Coordinate the sequence and tasksPreparation
Prepare the scope and commission together
The investigation objective and suitable methods are determined from the planned construction task and existing findings. Which activity may be commissioned privately under the specific North Rhine-Westphalia procedure is clarified separately before an agreement. For the quotation, the information required, affected area and contributions of other parties are identified. Where a project involves several specialist questions, the ordnance commission is described with its own intended results. Specialist preparation establishes which details are already sufficient and what information is still needed before the work.
Establish what needs to be known before commissioning the work
For the Bad Oeynhausen commission, the ordnance information needed for the excavation, foundation or borehole is described. Proposed areas, positions and depths are linked with existing results. This establishes whether documents first need assessment, further ground areas and volumes need investigation, or previously assessed findings require further work. The specialist service and results documents required receive their own scope. Medicinal spring protection requirements are clarified separately with the competent authorities for the same actual groundworks. A document from one procedure does not automatically answer the other specialist question.
Define the specialist taskCoordinate preparatory work with the investigation
Before investigation, the survey areas actually accessible, utility information and coordination with other trades are clarified. The preparatory work needed depends on the method and site. If investigation requires additional ground intervention or access, its location and depth are included in preparation. Those responsible coordinate the applicable requirements on specialist grounds. Breaking ground or changing the surface is not undertaken independently as incidental survey preparation. Outstanding prerequisites remain identifiable before the appointment.
Clarify preparatory work in the programmeAgree a clear scope and schedule
The commission describes the scope of specialist ordnance work and the conditions known for it. Areas that are only partly accessible are taken into account. Effort and timing depend on access, documents and coordination; assessment and handover of findings form part of the process. Any water law clarification needed in parallel retains its own competent authorities and documents. Construction planning brings together the respective stages of work for the groundworks concerned. An existing decision or report from one assessment task is not treated as establishing findings on all other ground-related questions.
Discuss the scope and scheduleTasks at the site
Plans that show both sets of questions
01
Location of the individual groundworks
Mark the proposed excavation and additional groundworks outside it. If borehole positions or utility trenches are planned, these must also be identifiable. For coordination, the specific area is more useful than a general description of the entire property. For an excavation, for example, the foundation footprint, proposed shafts and lateral utility connections are shown separately. Any axis relocated later is identified by a clear revision status. The specialist authorities involved can then identify which new part of the site needs assessment and which previous details still describe the same groundworks.
02
Planned depth with an elevation reference
State the depths of the proposed work and their reference to ground or design level. Different depths can raise different questions. Avoid a single combined figure where foundations, shafts and connections affect different parts of the ground. Use an understandable reference for existing and proposed elevations. A ground investigation report can provide information on the sequence of strata, but must be assigned to the correct site for this purpose. Where elevations differ or the ground has only been partly investigated, the outstanding question is identified and clarified before the documents are used together.
03
Existing findings
Provide ordnance documents in full. Supplementary ground investigation or water-related reports remain identified by their own investigation purpose. A positive decision on another specialist question must not be treated as a substitute for a missing ordnance report. The overview identifies the date, commission and associated plan attachments for each document. An earlier assessment of another structure is not assigned solely on the basis of a shared address. Specialist planning compares the ground area and volume actually investigated with the new work and records which findings can inform the next decision.
04
Investigation involving ground intervention
If the planned investigation itself requires ground intervention, this must also be described. Whether medicinal spring protection requirements apply must be clarified before the work. A blanket statement for every measurement or the entire town would be insufficient. For boreholes and groundworks requiring approval, Section 8 of the medicinal spring protection ordinance provides for a hydrogeological assessment with the expected sequence of strata down to the planned final depth. The documents required for the specific project are clarified with the competent water authority. An ordnance investigation and this hydrogeological assessment retain their respective purposes.
Project documents
Documents that establish the next step
Hand over evidence with its respective purpose
Ordnance reports, other specialist assessments and official decisions are assigned separately. Their areas, conditions and limitations remain identifiable. A joint overview makes them easier for site management to use, but does not extend the scope of any individual result or decision. The handover identifies the plans used and the spatially relevant findings for each construction phase. Site management receives the restrictions affecting its immediately forthcoming work. Outstanding conditions are recorded together with the responsible party and the next step required. When the contractor changes, this information is handed over in full. After clearance work has actually been carried out, the clearance record, including its scope and results, is assigned to the areas treated and the associated plan attachments.
Account for changes in all affected tasks
If an excavation is relocated or its depth changes, existing findings are compared with the plans again. Identify which specialist questions may be affected by the change. Further needs are coordinated specifically. A change to the construction plan alone is insufficient if other documents lose their relevance as a result. A deeper foundation may raise different questions from a simple shift on the site plan. Therefore state the changed geometry and affected documents in each case. Those responsible assess the change within their own specialist remit and bring their findings together with the current design. Any earlier quotation is related to the scope actually agreed.
Construction sequence
Coordinate investigation and construction sections
Describe the actual task before coordination
Bring together the site plan, depths and existing documents. Identify outstanding alternatives and requirements already clarified. The authorities involved can then relate their questions to the same groundworks. An early joint overview helps planning without anticipating an individual protection area or approval decision. For the service description, preparation, possible investigation, interpretation and handover are clearly distinguished. Identify who provides access, utility information and existing reports. Responses still outstanding are also identified with their actual processing status. The enquiry can then focus on the outstanding specialist task and proposed construction phase.
Check the current context before construction
Compare the proposed work step with existing results and decisions. Outstanding conditions are assigned to those responsible. Changes remain identifiable through to site management. Construction receives an understandable status for its specific area rather than a general statement for the whole town. Before work resumes, the plan revision and report version are checked together. A new site organisation receives the information relevant to its task on investigated, uninvestigated and partly assessed areas. The handover note identifies outstanding questions and the authority or party with whom further work is coordinated.
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. Images, their information value and the area boundaries considered are linked with present-day groundworks. The absence of a visible finding is not a technical investigation of the ground as it is today. Other existing findings are included. The area covered by historical analysis and a water law protection area boundary serve different purposes. Both map references remain identifiable with their respective findings during preparation. Historical assessment confirms neither every future ordnance question nor the permissibility of the proposed work under water law.
Understand aerial photograph assessmentMagnetometric survey
Magnetometric methods detect magnetic anomalies. Suitability is assessed according to expected objects, ground conditions, interference and the required investigation area and volume. Utilities, fences and existing structures can influence interpretation. Signal strength alone does not identify ordnance. Measurement, assessment and any further investigation required are planned together. The results report describes the ordnance findings actually achieved and their limitations. No general assessment of medicinal spring protection at the site is derived from them.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations may be suitable for certain metallic target objects and site conditions. Selection considers the information required, accessible survey areas and interfering installations, rather than equipment availability alone. Results include their location and the investigation conditions. Any supplementary method required follows from specialist assessment. Technical selection is linked to the specific task; further requirements for the proposed work are clarified with those responsible in each case.
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 commission. Before a radar report addressing other ground-related questions is used as ordnance evidence, its purpose and scope are checked. Each investigation retains its own subject matter in relation to an assessment under water law.
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. Positions, depths, elevation references, borehole layout and known utilities then form part of preparation. The provision of suitable investigation access is also planned on specialist grounds with those responsible. The proposed groundworks remain understandable to other competent authorities. A standard grid or general depth figure does not replace this planning. Results remain tied to the ground areas and volumes actually investigated and the method used.
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. 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 receives an allocation of specialist work, new findings and unresolved areas within the sequence. Requirements of other assessment tasks are coordinated with those responsible for them. The general term supervision replaces neither the specific specialist ordnance task nor the separate clarification under water law.
Agree the approach during constructionTechnical assessment
Relate methods and responsibilities to the task
Check ordnance findings
A historical aerial photograph analysis is related to the identified area and planned work. Protection of a medicinal spring does not in itself establish either a suspicion of ordnance or its exclusion. Both questions require the documents suitable for them and their own specialist assessment.
Define the investigation on specialist grounds
For a survey the question being investigated, ground conditions and existing installations matter. Which method is suitable and what information it can provide must be assessed for the project. Another official approval does not replace this selection or the assessment of measurement conditions.
Agree prerequisites in advance
The clearance plan can describe the ordnance measures required and their sequence. Requirements of other competent authorities must also be incorporated where necessary. Coordination of ordnance investigation should not be understood as permission to carry out all the groundworks proposed.
Next steps
Bring together outstanding points before construction
Describe the area and project
Prepare a clear site plan and the structure details required. Identify groundworks already decided and alternatives still outstanding. Those responsible can then identify which work actually needs assessment and where details are missing. For initial contact, state the project address, proposed work and current plan revision. Specialist planning checks existing ordnance reports for their area and depth references, limitations and identifiable gaps. It assigns official notes and investigations already carried out to their respective functions. The document overview identifies which results can be used for the new construction task and which question still needs an answer.
Supplement historical findings where needed
Existing aerial imagery analyses and historical indications are related to the present-day project area. Where the basis is incomplete, the necessary supplementary research or aerial imagery analysis is carried out through the appropriate specialist or official route with its question defined. The findings obtained are assessed together with previous use and current plans to determine investigation needs. An entry in the town's history is first checked for its actual relevance to the property.
Clarify the protection area context
Use the definitive maps and consult the competent authority to establish whether a protection zone is affected and which one. The ordinance distinguishes requirements by zone and activity. Do not derive a binding decision for an individual borehole position or excavation from a general overview. Investigation planning defines suitable methods according to the information required, depth of groundworks and actual site conditions. Existing utilities, installations and interference are taken into account. The commission describes its spatial scope and the prerequisites for carrying it out. The marked area remains linked to the specific construction task if a foundation or utility route changes.
Agree the documents required
For projects requiring approval, the protection area ordinance specifies the descriptions, plans and evidence needed for assessment. The competent water authority clarifies which procedure applies in the individual case. Other approvals that may already exist must be taken into account; not every case requires a separate additional decision. On the basis clarified, specialist personnel carry out the investigation or agreed supervision permitted within the relevant legal and technical scope. Data are recorded with their location, local measurement conditions and limitations. If conditions change, the further approach is coordinated. A suspicious find triggers the prescribed reporting and hazard prevention procedures.
Assess and clearly document findings
The data and findings collected are professionally assessed in the context of the investigation objective, method and site conditions. Interference and areas that cannot be investigated remain identifiable. The report documents the work carried out, results, location and depth references, and limitations; maps and attachments remain connected to it. Any further clarification required is assigned to the affected area. A measurement anomaly is professionally assessed and is not identified as a particular object solely on the basis of the measurement signal.
Reassess changes
If groundworks move or their depth changes, pass the new revision to the affected specialists and authorities. Check both the relevance of ordnance results and the other project-specific requirements. A change must not be updated in only one of several records. For the next construction phase, the assessed report and associated plans are handed over together. Site management compares its forthcoming work with the investigated area and documented limitations. Outstanding tasks receive a responsible point of contact and a link to the next groundworks. The plan and report revisions used remain traceable for later additions.
Documentation
Each item of evidence retains its subject matter
Findings and their scope
Ordnance documentation must identify what was investigated and what findings are possible for the areas treated. Water law decisions and supplementary assessments are assigned separately to their respective purposes. At handover to site management, the relevant plans, results and limitations should be available together without equating their findings.
Project responsibilities
FONTANA-EOD carries out and documents the agreed ordnance task. This does not replace decisions by other authorities. The BFR Kampfmittelräumung provide a basis for specialist planning; they apply directly to federal property. For other projects, they are used as specialist guidance alongside the specific local requirements.
Working approach
How FONTANA-EOD works
Document the agreed specialist service clearly
FONTANA-EOD carries out the agreed specialist ordnance task for the identified groundworks in Bad Oeynhausen. Before work begins, accessible areas and the results required are agreed. If planning or local conditions change, the scope is reviewed before the affected work. The report documents the actual work and its limitations. Site management can relate the findings to the next activity and identify outstanding ordnance questions. Medicinal spring protection documents retain their own subject of assessment. Preparation connects the two topics through the actual areas and depths, rather than by a blanket transfer of results from one to the other.
Discuss the investigation taskThe task before the equipment
Method selection begins with the information needed on the ordnance question. Specialist planning considers expected objects, ground conditions and actual investigation conditions. Available equipment or a similarly located neighbouring project is not sufficient as the sole basis. The selection is justified for the ground area and volume described. Further requirements for the work proposed as part of the investigation are clarified with those responsible; they are not derived solely from the name of the investigation method.
Keep limitations visible
Inaccessible areas and areas with limited interpretability are identified with their boundaries. Site management can assign outstanding specialist work and prerequisites to them. A general total-area figure does not replace this distinction. Planning and construction teams agree when a suitable investigation will become possible. If groundworks also require clarification under water law, this remains identifiable as a separate task. The documented state of ordnance knowledge is not implicitly extended to cover this other subject of assessment.
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 plans and their relationship to the ground area and volume previously investigated. Its response and any additions required are assigned to the groundworks. Other assessment tasks affected are checked with the competent authorities. The same property address or an ongoing project name does not in itself confirm that the task is unchanged.
Hand over the report and plan together
At handover, reports and associated plan attachments are assigned by subject of assessment and stage of work. An overview can list the findings on the ordnance question and separate medicinal spring protection documents, together with their outstanding tasks. It does not replace the respective documented scope. When site management or contractors change, the evidence relating to the actual groundworks remains traceable. The next activity is prepared using the appropriate results and coordination still outstanding.
Understand the results
Use technical statements for the next decision
A general map is not an individual decision
A specific ground intervention requires the exact location and definitive documents. An overview can help with orientation, but does not replace assessment of the specific boundary and activity. Clarify uncertainties with the competent authority. No blanket permissible depth is derived from the town's name.
Understand investigation reports and their limitationsThe investigation itself may also form part of groundworks planning
If the specialist task includes groundworks, their location and scope must be known. This information enables coordination of the requirements for carrying them out. The subsequent construction work remains distinguishable from them. Clarifying a question about the investigation does not automatically answer every question concerning the later construction project.
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 ordnance and medicinal spring protection in Bad Oeynhausen
Who is responsible locally for the ordnance question?
The town of Bad Oeynhausen identifies the local public order authority and support from the state explosive ordnance disposal service of the Arnsberg District Government. The private specialist scope commissioned and official duties must be distinguished. Before the affected groundworks, clarify the procedure required with those responsible.
Does the same medicinal spring protection rule apply to every area?
No. The ordinance distinguishes protection zones and individual activities. For a specific project, the exact location and definitive maps and provisions must be checked. A blanket depth limit for the whole town cannot be derived from them.
Does a water law approval replace ordnance investigation?
No. It answers a different specialist question. Existing ordnance findings must be related separately to the proposed groundworks. Equally, an ordnance report does not replace a decision required for medicinal spring protection.
Must an investigation borehole also be coordinated in advance?
If an investigation involving ground intervention is proposed, its location, depth and execution must be included in preparation. The requirements applying in the affected protection area must be clarified with the competent authority before the work. This does not imply a blanket additional approval requirement for every investigation.
What should I do if I find a possible item of ordnance?
Stop the affected work and leave the object untouched and unmoved. Keep your distance and keep other people away. From a safe distance, notify the police immediately by calling 110 and follow the authorities' instructions.
How are different official decisions recorded within the project?
With their respective subject matter, spatial reference and conditions. A joint overview does not replace the separate findings of each decision.
Which changes are passed to all affected authorities?
In particular, changes to the location, depth and execution of the groundworks. The further steps resulting from them are specifically coordinated for the specialist questions affected.
Why must the investigation appear on the site plan, and which cost factors matter?
Where the investigation itself involves ground intervention, its scope and location must be identifiable. Requirements for this work must be distinguished from the later construction work. The effort also depends on the size and accessibility of the area, proposed depth of groundworks, suitable methods, interference and usable previous findings. Preparatory services, interpretation and documentation required are agreed with their scope for the specific task. Cost information for official hazard prevention is distinguished from privately commissioned services.

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.
