Ordnance assessment in Lippstadt before construction starts
Your building permit contains an ordnance assessment note and construction is approaching: which documents are still missing, and who initiates the investigation? FONTANA-EOD helps you with specialist preparation of an explosive ordnance survey for your Lippstadt project. The basis is existing findings, official requirements and the groundworks actually planned.
Read the notes together with the site plan and construction method.
Clarify local procedural status early.
Align investigation with the planned ground interventions.
Assess the construction project
Identify outstanding tasks clearly before construction starts
A planned date does not establish a completed investigation. For your Lippstadt project, we link the building permit notes to the actual groundworks and existing results. Coordination still needed and a permissible specialist service are assigned specifically.
Project site
Connect the site with the specific construction task
Link the municipal application and specialist planning in Lippstadt
The town of Lippstadt identifies its public order office as responsible and the Westfalen-Lippe explosive ordnance disposal service as specialist support. According to the town, property investigations by the state service are carried out at the town's request. Permit notes, today's ground interventions and existing results are assigned to this procedural status for your project.
For local coordination, provide the address, cadastral plot and planned intervention areas on the current site plan. Include the building permit notes and all associated annexes. State which investigations have already been performed and which reports are available. Add the current plan version and identify changes from earlier enquiries. For several construction sections, clearly identify the work due first. Responses still missing remain identifiable by their actual processing status. Planned construction is coordinated using this complete information. Further project locations are listed in the regional overview.
On its procedural page, the town of Lippstadt asks for the work to be registered at least two weeks before construction starts. It also warns that individual cases may involve substantial lead times. The registration lead time and steps actually needed for investigation, assessment and coordination are considered separately in the construction programme. A requested date, confirmed work and handover of interpretable results remain clearly identified. Coordinate the document status and outstanding steps with the public order office early. The earthworks sequence is related to this actual processing status with those affected.
The overview of the Arnsberg administrative district provides further local information for the regional context of your construction project.
Local context
What should be clarified before the first ground intervention
Observe Lippstadt's permit notes and municipal application procedure
For investigation of construction sites, the town of Lippstadt refers to the building permit notes and recommends early contact. According to the town, a property investigation by the state explosive ordnance disposal service takes place only at the town's request. A private commission to a specialist contractor does not replace this procedural step.
The history of Lippstadt describes how the town was largely spared bombing despite several businesses producing for the armaments industry. For a specific construction area, available historical information is assigned spatially and assessed using suitable aerial photographs, construction files and other documents. Former uses, subsequent conversion and documented ground changes are brought together with today's ground intervention. Regional history and property-specific ordnance assessment serve different purposes. Specifically assigned findings and the status of the official procedure remain decisive for further planning.
Compare planned work with existing results
Provide not only the planned date but also the areas and depths of the work. A foundation, excavation and utility connection may require different ground interventions. The permit and existing reports must identify which questions have already been answered and which still need coordination with the responsible authority.
For new groundworks, the applicable construction plans are compared with the documented investigation status. An additional utility, larger excavation or changed foundation may affect different areas and depths. Such changes are marked as specific positions on the plan. Existing results remain assigned to the area they actually cover. The specialist finding still needed is defined for the new work and agreed with those responsible. Site management can then identify which tasks must be addressed before each ground intervention.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For the commissioned work, the applicable technical requirements, permits, competence and responsibilities are clarified. The actual scope of work is what matters. Tasks and interfaces are described for the project and checked against the required authorisations.
Link occupational safety to the construction sequence
The risk assessment, work areas and communication arrangements must suit the planned activities. Specialist explosive ordnance work is coordinated with the other construction activities. Site organisation, traffic safety and other technical assessments retain their own responsible parties. Joint coordination assigns the relevant specialist work and responsibilities to the affected construction sections.
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.
The town of Lippstadt explains investigation of construction sites and excavations, and the town's application for deployment of the state explosive ordnance disposal service. The KampfmittelVO NRW governs state tasks and the prerequisites for certain private activities.
The principles of clearance planning connect the investigation with its subsequent treatment. The geophysics guidance in the BFR KMR supports technical method selection. The documentation requirements relate results to the areas addressed. The North Rhine-Westphalia Ministry of the Interior explains state explosive ordnance disposal.
The BFR KMR describe specialist work on federal properties. Local requirements and responsibilities are established separately for the Lippstadt project.
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. The private contract connects technical suitability with the scope provided for in law. The authority's state of knowledge and the permissions required for the activity are checked before an agreement.
Working together
Distinguish the tasks of client, designers and specialist contractor
Client and operator
The client describes the project and provides the available project records. The operator adds requirements for use, access and timing. A coordinating contact brings the parties together; individual tasks remain assigned to the named parties. Before commissioning, it is clearly recorded what information is missing, who will obtain it and what decision the result is intended to prepare.
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 work. Requirements and decisions of public authorities are addressed with the responsible bodies. The documents needed for a particular procedure depend on the location and project. The technical report describes the work carried out, including its documented area, depth and scope. Decisions reserved for public authorities are made by those authorities.
The Lippstadt public order office is the local contact for coordinating ordnance assessment. The state Westfalen-Lippe explosive ordnance disposal service at the Arnsberg District Government supports the local authority within its remit. According to the town, this service investigates properties at the town's request. Permissible private specialist tasks have a specifically agreed service scope. Designers provide the current ground intervention plan and known changes. For project locations outside Lippstadt, local responsibility follows the actual project address. A need for ordnance recovery is coordinated with the permissible task and the competent authorities.
Investigation task
Which specialist task comes next?
Determine the need from the note and ground intervention
The permit details are considered together with existing findings and the current construction method. This defines the outstanding specialist question. A general note does not determine a particular survey method without assessment. Area, depth and investigation site conditions remain decisive for further planning.
Assess historical documentsDistinguish a permissible addition from a state task
The municipal procedure and a private specialist commission serve different purposes. Before an agreement, record what service is needed and its scope. The specific legal prerequisites in North Rhine-Westphalia are considered. Specialist support does not replace any decision or commission still required from the responsible authority.
Compare investigation methodsProject types
Base the construction start on a traceable status
Pass on requirements in full
A building permit note is needed in its exact wording and with associated annexes. Designers must be able to identify the area and activity it concerns. A short summary may obscure conditions or outstanding steps. Keep the file reference and applicable plan version together too.
Document findings and their limitationsDistinguish dates by their purpose
The enquiry, confirmed investigation date and planned construction start are different details. State which date is agreed and which is merely requested. Further scheduling also considers which results remain outstanding. An entry in the construction programme is not evidence of completed specialist work.
Coordinate the sequence and tasks
Assign responsibility for responses
Identify who receives official responses and passes them to those affected. Complete documents should reach designers and site management. Information given by telephone is assigned to the correct process. This keeps traceable which decision rests on which finding and which question still needs clarification.
Specialist services and investigation tasksPreparation
Prepare the scope and commission together
The following specialist topics explain possible investigation tasks. Which activity may be privately commissioned under the specific North Rhine-Westphalia procedure is clarified separately before an agreement.
Establish what needs to be known before commissioning the work
For the Lippstadt project, provide the building permit notes with the site plan and annexes. The commission describes what finding is still missing for the earthworks due first. Existing results are assigned to the planned areas and depths. This distinguishes whether documents first need assessment, further volumes of ground need investigation or already assessed findings need further work. Necessary specialist work and result documents have a clear scope. Registration, investigation work and handover of assessed results remain different processing stages.
Define the specialist taskCoordinate preparatory work with the investigation
Before investigation, clarify the survey areas actually accessible and utility information available. Site management coordinates necessary access and interfaces with other trades. The method and site determine what preparation is needed. Additional breaking out or other ground interventions to create survey access are prepared by specialists beforehand, rather than undertaken independently. Outstanding prerequisites are linked to the investigation date. A calendar week identified for construction to start does not, by itself, describe suitable survey conditions.
Clarify preparatory work in the programmeAgree a clear scope and schedule
For construction scheduling, record which official responses and investigation results are already available and what remains outstanding. Distinguish the local registration lead time from the actual time for investigation, assessment and handover. If an area is only partially accessible, include this at commissioning. Effort and dates are agreed after clarifying scope, access and prerequisites. The earthworks sequence is related to actual processing status. A desired construction start is not treated as an investigation status already achieved.
Discuss the scope and scheduleTasks at the site
Four documents for coordination before construction starts
01
Permit notes
Pass on the complete wording with associated annexes. A shortened note such as “check ordnance” leaves unclear which area is meant and what further documents already exist. Also record the file reference so questions can be assigned to the correct process.
02
Groundworks plan
Show planned ground interventions on a current plan. Where relevant, include the excavation, foundations, utility routes and other groundworks planned. Add their respective depths and identify design options still open. The property boundary alone does not describe the construction task.
03
Existing results
Include existing aerial photograph analyses and technical investigation reports with maps. Check the date and investigated area. A result for an earlier construction section can be used only insofar as its documented area, depth and question fit the new work.
04
Sequence and contacts
Identify who receives official responses and passes them to designers and site management. Distinguish the desired construction start from investigation dates already confirmed. Outstanding coordination belongs in the programme so a requested date is not inadvertently treated as a completed procedure.
Project documents
Documents that establish the next step
Link results to the planned construction phase
Check whether the documented area and task cover the forthcoming work. An investigation for another section is not transferred automatically. Additional connections or changed depths are considered too. Site management is told which documents apply to its specific work area.
Assign permit notes with their dates, file references and annexes to the current project. Existing reports are recorded with their investigation objective and the area addressed. When plans change, it remains clear which version was originally submitted for investigation. A document register identifies missing annexes and responses still awaited. Specialist work can then build on actual knowledge. Those involved use clear labels for construction section, structure and depth reference when asking questions.
Preserve outstanding steps at handover
A summary project status must not obscure missing reports or areas only partially addressed. Explicitly record the findings still needed. Further planning can then assign these tasks to a contact and section. Actual work produces the respective state of knowledge, rather than commissioning alone.
Handover of results identifies usable findings, limitations and outstanding tasks. Maps and report are provided as a matching set. Site management checks with the specialists which forthcoming activities are covered by the results. Changed areas and depths are assessed separately before construction. Official responses retain their own subject in the file. For later design changes, the documented status is related to the positions actually affected. After clearance work, the clearance record with its scope, results and limitations supplements the evidence for the positions actually treated and associated plan version.
Construction sequence
Coordinate investigation and construction sections
Organise the documents before agreeing dates
Compile the permit, current plans and existing results in full. Identify missing annexes and outstanding responses. The next necessary tasks are derived from this status. An early desired construction start is treated as planning information, rather than evidence of prerequisites already fulfilled.
Compare again before the affected work step
Check the applicable plan version and associated results. Changes to area, depth or construction method are communicated to those involved in good time. Ground interventions not yet covered receive separate specialist assessment. Site management receives a traceable document set with the limitations actually applicable to the findings.
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. For the next earthworks, available images, their interpretability and the area boundaries considered are checked. The absence of a visible indication is not a technical investigation of today's ground. The analysis is linked to further findings and the applicable construction design. A permit requirement and an analysis result actually available are passed to site management with their respective status. Historical assessment does not generally confirm all future work.
Understand aerial photograph assessmentMagnetometric survey
Magnetic methods detect magnetic anomalies. For the finding needed before construction starts, consider expected objects, ground conditions, interference and the investigation area. Fences, utilities and existing structures can affect interpretation. The method is planned according to these conditions, rather than the desired date alone. A signal's strength does not identify it as explosive ordnance. Measurement, assessment and necessary further clarification belong together in the specialist commission and handover of results.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations may suit certain metallic targets and site conditions. The finding required, accessible survey areas and existing interfering installations are decisive. Instrument availability and the desired construction start do not replace specialist justification. Results are documented with their locations and actual investigation conditions. Whether a supplementary method is needed follows from assessment. Site management needs the assigned result status for the activity concerned, rather than merely information about the planned survey date.
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 an ordnance finding; an area without notable signals does not confirm any arbitrary depth. Interpretation and limits are documented with the commission. An existing radar plan prepared for other tasks is checked for purpose and scope before use as ordnance evidence. For the next ground intervention, what matters is the finding actually achieved, rather than the existence of a plan alone.
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. Location, depth, borehole layout and existing utilities then form part of preparation. Suitable investigation access is also planned by specialists. A standard grid or general depth figure does not replace this task. The sequence needed is agreed before the affected work. 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 the proposed construction programme. Visual observation of excavated material alone does not replace a necessary survey. Site management receives a description of when specialist work takes place, how new findings are handled and which areas remain unresolved. A tight schedule alone does not justify a suitable approach accompanying construction; the task and prerequisites actually agreed are decisive.
Agree the approach during constructionTechnical assessment
The investigation follows the construction task
Assess the findings
A historical aerial photograph analysis answers different questions from a technical field investigation. For planning, check which indications it contains and which area it refers to. Missing images and analysis limitations remain documented with the knowledge actually gained.
For scheduling, specialist work steps are recorded with their prerequisites. Before an investigation, compile necessary plans, access and utility information. For parts already supported by evidence, compare their spatial coverage with the new work area. Areas not yet accessible are assigned separately within the programme. The investigation itself and subsequent specialist assessment are planned as related tasks. Also record when complete results with associated plans are needed for construction. A changed earthworks sequence is compared with the investigation status before the affected ground intervention.
Where several contractors are involved, site management identifies the working areas affected first and contacts for the information needed. Preparatory work such as creating access routes, opening a surface or additional utility excavations is shown with location and depth. Where it involves ground intervention itself, include it in specialist coordination already. If access to the investigation area changes, clarify whether the agreed work can be undertaken under these conditions. Differences are documented with the plan version and section affected. Those involved receive the same traceable version for further preparation.
Select survey methods
If a survey is necessary, the method must fit the investigation objective and property. Utilities, installations and buildings may affect measurements. A general statement about achievable depth therefore does not replace assessment of specific survey conditions and the intended construction method.
Justify the next steps
The clearance plan records what is to be investigated and how identifiable limitations will be handled. Additional measures follow from specific needs. Explosive ordnance clearance during construction is not a blanket substitute for a necessary prior investigation; merely observing excavation is insufficient.
Next steps
From the first enquiry to handover to site management
Initial contact and assessment of the evidence
At first contact, describe the planned groundworks and decision needed. Building permit notes, existing aerial photograph analyses and technical reports are compiled with their annexes. If historical information is missing, the necessary aerial photograph analysis is initiated through the responsible local authority. Outstanding use or ground-condition information is researched and assessed using supplementary records and images. Findings are assigned to the planned intervention area.
Coordinate methods and responsibilities
Outstanding investigation needs are compared with official requirements and the planned construction method. The suitable method depends on ground conditions, targets, depths, interference and access. State measures and permissible private specialist tasks are assigned to their respective commissions. Required result documents and execution prerequisites are recorded. Those involved use the same current plan version for further coordination.
Investigate and assess results
The agreed survey or suitable supplementary specialist supervision is undertaken under the agreed conditions. Data and observations are interpreted by specialists and assigned to the areas actually addressed. Assessment distinguishes usable results, anomalies and locations with restricted interpretability. Differences from the planned work remain documented traceably. Further investigations or coordination follow the specific specialist question remaining.
Document findings and prepare the subsequent decision
Complete reports are handed over to site management with plans, scope and limitations. Before the next ground intervention, location, depth and construction method are compared with the documented investigation status. Additional or changed work is assigned separately. Specialist work still needed and official decisions are coordinated with those responsible before the affected construction step. Handover identifies the status actually achieved and the tasks remaining.
Documentation
Bring investigation status and construction start together
Assess responses according to what they actually concern
Keep application documents, confirmed dates, official responses and specialist reports with their associated plans. For construction planning, document the investigation actually performed with its spatial scope and limits. Identify each response's purpose so scheduling coordination and specialist results are clearly assigned within the construction programme.
Project responsibilities
The BFR Kampfmittelräumung describe specialist work on federal properties and provide specialist guidance outside their direct scope. In Lippstadt, local requirements and North Rhine-Westphalia responsibilities remain decisive. FONTANA-EOD documents the agreed specialist service with the scope actually addressed. Competent authorities make official decisions.
Working approach
How FONTANA-EOD works
Document the agreed specialist service clearly
FONTANA-EOD undertakes the agreed specialist task for the Lippstadt groundworks described and current document status. Accessible areas and results needed are agreed before work begins. If plans or local conditions change, the scope is reviewed against them before the affected work. The report documents the actual work and its limits. Site management can then identify the specialist basis available before each activity and what remains to be clarified. An agreed date and a delivered investigation result retain their different functions.
Discuss the investigation taskThe task before the equipment
Method selection starts with the finding needed for the ground intervention due first. Specialist planning considers the volume of ground, existing knowledge and actual survey conditions. An available instrument or similar neighbouring site alone is not sufficient. Even when construction is approaching, the method is justified by specialists. Necessary investigation, interpretation and handover of results are coordinated with construction planning.
Keep limitations visible
Inaccessible survey areas and areas with restricted interpretability are identified with their location and limitation. Site management can assign the relevant earthworks and additions still required to them. A finding for the entire construction area is supplemented by these limits. Planning and construction teams agree when a suitable investigation can be undertaken. A date for another area already addressed is not transferred unchecked to the unresolved area.
Clarify changes before intervening in the ground
New locations, additional depths or different construction methods are compared with existing results before the affected activity. Specialist planners receive a clear account of the change from the earlier version. Their response and necessary additions are incorporated into the programme in good time. An unchanged construction start entry or project name does not replace this comparison. Planning remains tied to the actual volume of ground and associated specialist finding.
Hand over the report and plan together
The report and associated plans are handed over to site management as a matching result set. A short overview can identify the findings, limitations and outstanding tasks important for the next activity. It does not replace the documented investigation scope. When site management or contractors change, applicable official documents are also passed on. The basis for the planned earthworks remains traceable, rather than merely carrying forward the project's originally agreed start.
Understand the results
Use technical statements for the next decision
A building permit may require further steps
The specific notes and documents determine whether and which tasks still need clarification before a ground intervention. A permit is therefore not assessed by its title alone. Associated annexes and later responses are read together. Actual construction depends on the status relating to that work.
Understand investigation reports and their limitationsA confirmation needs a clear subject
Each response should make clear whether it concerns a date, application or specialist result. Keep its connection with the relevant process. A shortened message may blur these distinctions. Complete documents allow later participants to assign them correctly to the planned construction task.
Understand the service scopeDesign and findings

Process and documentationQuestions from planning
Questions about construction preparation in Lippstadt
Can I commission the state explosive ordnance disposal service myself?
For property investigations, the town of Lippstadt specifies the town's application as a prerequisite for deployment of the state explosive ordnance disposal service. Clarify the intended route with the public order office. A private specialist commission is distinct from this.
Does a building permit mean the ordnance assessment is already complete?
Read its notes and annexes. They may require further steps. Associated documents must establish whether a necessary investigation has already been performed and which work its results cover. Coordinate investigation needs with those involved early, before the planned groundworks. For the enquiry, compile the site plan, cadastral plot, intervention areas and depths with complete reports and maps.
Does a registered date establish a fixed construction start?
No. Registration establishes neither a confirmed investigation date nor a final result. Coordinate the construction programme with those responsible and consider which responses or services remain outstanding.
Must an earlier investigation be repeated for an extension?
Not automatically. First compare the documented area, investigation depth and limits of the findings with the newly planned ground interventions. Only this establishes whether further documents, coordination or investigations are needed. Method selection considers ground conditions, targets and interference. Areas with restricted interpretability remain documented with their limits.
What should I do about a suspicious find during the work?
Stop the affected work and do not touch or move the object. Move away, keep other people away and notify the police immediately on 110. Follow the emergency responders' instructions.
What information helps agree an investigation date?
The specific ground intervention with location and depth, complete existing documents and the status of official processing. Explicitly identify responses and prerequisites still missing. The sequence links document review and necessary historical analysis with method selection, investigation or suitable supervision, assessment and documentation. Results are compared with the plans before subsequent work.
Which factors determine effort and costs?
The scope, method, depth, interference and access determine the effort required. Supplementary investigations and necessary preparation are identified as specific tasks. The service agreement describes the permissible private commission and intended result documents. Cost allocation is coordinated with those involved in the specific process. The work steps actually needed and their applicable prerequisites are decisive.
What is reviewed if the construction start changes?
The current plans and findings, and the steps still needed. A date change does not extend an existing investigation or replace outstanding coordination. For partially addressed areas, findings achieved and unresolved areas are recorded separately. The subsequent construction programme is related to specifically documented coverage.
Project enquiry
Prepare the first technical discussion
Include permit notes
Send complete notes and annexes with current ground intervention plans. Add the project address, cadastral plot, official responses and complete reports with their maps. Known utilities, geotechnical information and existing historical analyses form part of the comparison. The sector overview explains typical interventions and the documents they require.
Identify the outstanding status
Distinguish requested dates, confirmed steps and results actually available. Identify the construction area, route, boreholes, intervention depths, construction schedule and decision needed. Mark design options still open and areas not yet accessible.

Have your project assessed
Whether historical aerial photograph analysis, explosive ordnance surveying, surface surveying using GPR, magnetometry or TDEM, deep-ground surveys, downhole surveys, excavation supervision, area clearance or ordnance recovery is needed depends on the location, ground disturbance, depth, ground and existing documents. An early ordnance assessment provides clarity for tendering, programming, occupational safety and construction.
FONTANA-EOD combines its Section 7 SprengG licence, specialists holding Section 20 SprengG certificates of competence, suitable survey and clearance methods, and traceable documentation. Send the site plan, depth of ground disturbance, construction phase and existing documents for an initial technical assessment.
