Compare test areas with the proposed construction area
If your construction area in Neustadt an der Weinstraße lies within an area of suspected explosive ordnance, we clarify investigation needs before the groundworks concerned. We read existing reports according to their specific tasks. A test survey may help select a suitable method; its area and limits of findings remain decisive. Further investigation needs are coordinated with the proposed groundworks and conditions throughout the work area.

Investigation documents for construction planning
Neustadt an der Weinstraße is an independent city in Rhineland-Palatinate. The documents for the building committee meeting of August 2026 list preliminary investigation and test surveys separately. The survey record of January 2024 gives different assessments for the test areas; interpretability is linked to their respective conditions. For your project, it is correspondingly assessed which existing findings fit your own area and the investigation still required.
Identify the project address, cadastral district and parcels actually concerned. Municipally published reports about the state garden show concern their respective described areas and planning statuses at that time. The spatial reference of an investigation is therefore compared with the current construction area. For a project outside the city, the responsible office depends on the specific municipality and federal state. Even connected infrastructure measures assign documents to individual sites. Requirements from another project are clarified using your own task and the competent authorities. Further project locations are shown in the regional overview.
The overview of the SGD Süd provides further local information for the regional context of your construction project.
Local context
Preliminary investigation and test surveys in Neustadt
Assess preliminary investigation and test surveys separately
The documents for Neustadt's building committee meeting of 27 August 2026 list a preliminary explosive ordnance investigation and survey record for test fields separately for the state garden show. The preliminary investigation of 4 May 2021 was prepared by Luftbilddatenbank Dr. Carls. The record by analytec Dr. Steinhau of 29 January 2024 addresses interpretability of geophysical test data. These are documents by other companies for a specific project.
The historical preliminary investigation describes bombing traces, positions, communication trenches and a pit from the Second World War in parts of the project area at that time. Further investigation needs were identified for designated areas. Such findings are related to current plans using the associated results map and explained limitations. Assessment remains bound to the area investigated. Another area requires assessment of its own information and proposed interventions.
Compare existing results with present-day plans
Anyone proposing construction on a property or modification of an existing installation should therefore first read a report's task description. A test of a survey method's suitability is not already a full investigation of all later intervention areas. Conversely, an existing result need not be discarded merely because it comes from an earlier planning phase. Its spatial reference, depth investigated and limitations described must be compared with the present-day project.
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 municipal building committee documents of 27 August 2026 contain, for the state garden show plans, the preliminary explosive ordnance investigation of 4 May 2021 and the survey record of 29 January 2024. Historical analysis and technical test surveying retain their respective described investigation purposes.
The BFR KMR guidelines on clearance planning describe preparation of the specialist task. The geophysics guidance explains investigation methods; the documentation requirements support traceable handover of results. The DGUV FAQs on explosive ordnance clearance address the technical requirements of investigation accompanying construction. The ADD task description explains the tasks of the state service and separate private precautionary work.
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.
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 company addresses the agreed investigation and documentation scope. Official requirements are clarified with the respective competent authorities. Documents required for a specific procedure depend on the site and project. The technical report describes the specialist service carried out within its documented area, depth and service scope. Official decisions are made by the respective competent authorities.
In Rhineland-Palatinate, local regulatory authorities are generally responsible for hazard prevention; where delay would create danger, the police are responsible. The state explosive ordnance clearance service supports these bodies with specific hazards through administrative assistance. For a preventive project, the private specialist service required and local requirements are coordinated with the responsible parties. If the investigation establishes further clearance needs, subsequent specialist work and involvement of the competent authority are coordinated before execution.
Investigation task
Which specialist task comes next?
Compare methods using the specific task
Selection considers the findings required and conditions actually encountered. Existing test data may help assess suitability and limitations. Their assessment is linked to the areas investigated and objective at that time. Equipment is therefore not selected solely because it was used on another local project.
Compare suitable investigation methodsDescribe the outstanding question where interpretability is limited
If a method cannot sufficiently provide the findings required, the remaining task is identified specifically. The subsequent technical approach is developed from this. Documentation also records the areas concerned. A section with insufficient interpretability must not be replaced by a favourable assessment of a neighbouring test area.
Compare investigation methodsProject types
Reuse test survey findings correctly
Establish the question investigated first
Check whether a report assesses historical indications, examines a method's interpretability or documents another specific task. These purposes are distinguished when results are reused. A successful survey initially answers its agreed question. A document's title alone describes neither the entire scope addressed nor the results that can be derived from it.
Document findings and their limitations
Locate test fields clearly
The location and boundaries of the fields investigated are compared with the current construction area. Identify areas with different surfaces, installations or access conditions. Spatial proximity is insufficient to assume identical survey conditions. Comparison shows which results can be used for further decisions and where additional specialist clarification remains necessary.
Specialist services and investigation tasksRetain the investigation objective during assessment
Findings about interpretability are bound to the task investigated. Therefore document the question to which an assessment relates. For a changed task, transferability is assessed by specialists. A positive result for one objective must not become unrestricted suitability of the method in a short summary.
Document findings and their limitationsPreparation
Prepare the scope and commission together
Establish what needs to be known before commissioning the work
First establish which decision the commission needs to support. Is the task an initial assessment of existing documents, an investigation of a specific area or examination of an anomaly that has already been assessed? These tasks require different evidence. A general wish for safety does not define an investigation that can be carried out. The enquiry therefore specifies the groundworks, location, depth and available findings. Suitable specialist work and the required reporting are then agreed on that basis.
Define the specialist taskCoordinate preparatory work with the investigation
Required access and survey conditions are clarified before the site visit. This may include keeping areas clear, obtaining service information and coordinating with other trades. The method and site determine which preparations are actually needed. Changes to the surface or additional groundworks are not undertaken unilaterally simply to prepare for a survey. Their sequence is agreed with the specialist designers and responsible parties.
Clarify preparatory work in the programmeAgree a clear scope and schedule
A realistic programme distinguishes technically resolved work from prerequisites that are still outstanding. If only part of a site will be accessible, the commission must take this into account. Handover and assessment of the results also need time in the construction programme. The schedule and effort are agreed once the scope, access and prerequisites are clear. This coordination brings together the specified scope, access, documents, site conditions and the date by which a decision is needed.
Discuss the scope and scheduleTasks at the site
Sort documents by purpose
01
Provide preliminary investigation with appendices
A historical assessment includes the information described and maps to which the result relates. Pass on the complete report. A single overview from a presentation does not reliably show the information assessed and questions left outstanding. Also identify whether the project area at that time matches today's construction area.
02
Show test areas on the site plan
For existing test surveys, identify where they took place and what they were intended for. Conditions in one accessible subarea need not be identical everywhere. Filling, installations or a different surface structure may limit transferability. This question belongs in specialist assessment before a survey result is used for additional areas.
03
Describe groundworks specifically
In addition to the building footprint, utility trenches, shafts, foundations and preparatory exploratory works matter. Supply their proposed location and depth. Identify variants still present in the plans. A commission can then be tailored to the approaching decision rather than inadvertently covering only the excavation pit initially shown.
Clarify the sequence of exploratory work, investigation and construction for individual sections. Preparatory exploratory works, equipment setup areas, temporary utilities and additional working spaces may also require ground intervention. State when these areas are accessible and which operational restrictions exist. The specialist service needed can then be scheduled before the work step concerned. Changes are communicated with their location, depth and associated plan revision. This helps coordination where several companies work simultaneously and prevents a preparatory intervention from being overlooked in investigation commissioning.
04
Treat ground conditions and explosive ordnance separately
A geotechnical report examines different questions from a preliminary explosive ordnance investigation. Both may matter for the same property and contribute information to planning. The mere existence of a geotechnical report does not demonstrate completed explosive ordnance assessment, however. Record which specialist report supports which findings and where additional information is needed.
Project documents
Documents that establish the next step
Pass limitations on with the results
Supply complete reports and appendices, including statements about insufficiently interpretable areas. This information forms part of the result. It enables traceable planning of further steps. If only a favourable individual assessment is adopted from the summary, the actual findings of the complete report may be lost.
The project file records the investigation objective, areas addressed, methods used and result assessment together. A test survey includes the conditions actually tested and the prescribed interpretation objective. A later commission clarifies which additional findings are required. A clearance record documents clearance work carried out for its actual area. Site management receives complete documents, including remaining tasks. Where several specialist companies or plan revisions are involved, author, date and respective service scope remain identifiable when passed on. For necessary area clearance or recovery, the task, area and permissible responsibility are clarified before execution. Records subsequently handed over describe the work actually completed. They are brought together with the plans used and outstanding tasks.
Identify plan changes relative to test conditions
A subsequent surface change, additional development or different intervention may affect comparison with a test survey. Record such changes with the current plan. Specialist planning can then assess the findings that still apply. An earlier test is thereby neither automatically invalidated nor transferred to new conditions without assessment.
Construction sequence
Coordinate investigation and construction sections
Bring report types and areas together before commissioning
Supply historical knowledge, test records and current plans with their respective appendices. The investigation still required is described using this basis. Questions already addressed and those still approaching remain visible. The next commission thus receives a traceable purpose and clearly defined spatial scope.
Establish the next steps after the test survey
Results are assessed for the findings they enable about further investigation. The scope, prerequisites and remaining limitations of the next step are then agreed. Test fields remain identifiable in documentation. Transition to further work is planned explicitly rather than inferred solely from the existence of a survey record.
Method selection
Select methods according to the task and survey conditions
Historical records and aerial photographs
Historical aerial photograph assessment and other old records help place the basis for suspicion in its spatial context. The available images, their evidential value and the limits of the area considered matter. The absence of an identifiable indication must be distinguished from a technically surveyed ground area. The assessment is considered together with the planned intervention and other available findings. It can support the choice of a survey, but is not a measurement of the present-day subsurface or confirmation for all future works.
Understand aerial photograph assessmentMagnetometric survey
Magnetometric methods detect magnetic anomalies. Whether they can address the specific survey task depends, among other things, on the expected objects, ground conditions, interference and required survey area. Fences, utilities or existing structures may affect interpretation. A measurement signal is therefore not described as ordnance solely because of its strength. Method, interpretation and any further investigation are planned as a connected specialist task.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations can be suitable for particular metallic targets and site conditions. Their suitability must be explained for the task, rather than inferred simply from the availability of equipment. Interfering installations, accessible areas and the findings required must also be considered. Results are documented with their location and survey conditions. The specialist assessment determines whether a supplementary method is needed; this remains a project-specific decision.
Understand electromagnetic surveyingGround-penetrating radar
Under suitable conditions, ground-penetrating radar can provide information about subsurface structures and reflections. Ground conditions, moisture, installations and the particular survey task affect interpretability. An anomaly is not automatically ordnance, and an area with no apparent anomalies is not general evidence for arbitrary depths. The specialist interpretation and its limits are documented with the instruction. A survey for another purpose is not adopted without checking as ordnance evidence.
GPR and limitationsDeep-ground and downhole surveys
For deeper groundworks, it may be necessary to establish whether a surface investigation can provide the required findings or another approach is needed. Preparation includes the location, depth, borehole layout and existing services. Creating access for the investigation must also be properly planned by specialists. A general depth figure or standard grid cannot replace that work. Findings remain limited to the areas actually investigated and the method used.
Prepare deep interventionsSurvey during construction
If a necessary advance investigation cannot be completed in full, it is assessed whether a specialist-planned approach accompanying construction is suitable. This includes coordinated investigation, interpretation and communication of findings within the proposed work sequence. According to the DGUV FAQ, visual observation alone during excavation does not meet the state of the art. Site management needs a clear description of when specialist work takes place, how new knowledge is handled and which areas remain outstanding.
Agree the approach during constructionTechnical assessment
From existing data to the appropriate investigation
Assess historical indications
An aerial photograph analysis provides knowledge about earlier events and possible suspected areas. Further work follows from the result and proposed intervention. Existing documents should therefore be read by specialists before a technical service is commissioned. A short note without a map and task description often provides too little information for this.
For explosive ordnance assessment before construction projects in Neustadt an der Weinstraße, historical information is linked to the next proposed intervention. If this information is incomplete, research or aerial photograph analysis required is planned as a separate specialist task. The objective, areas and depths are established for technical investigation. An earlier test report is used with its investigation objective and conditions actually examined at that time. Interpretability information remains distinguishable from the later assessment of findings required. Site management thus receives a traceable description of what needs specialist clarification before the proposed construction section.
Clarify the survey's limits of findings
For a survey, what matters is whether the findings sought can be achieved under the conditions of the construction area. A survey pass alone does not yet answer this question. Areas that were inaccessible or did not permit sufficient interpretation must also be recorded. Further investigation tasks may result; a particular method does not follow automatically.
The test fields assessed in the published survey record show the importance of site conditions for investigation planning. Filling, metal installations, utilities or a changed surface structure may limit transfer of earlier results. A new section therefore considers the investigation objective together with the conditions encountered. If areas remain insufficiently interpretable, their location and outstanding question are documented. A supplementary method is selected for its suitability for precisely this task. The selection is coordinated with specialist planning before the next groundworks are derived from it.
Address outstanding areas before groundworks
Where a clearance plan is required, it should relate the knowledge and measures still needed to the construction programme. According to the DGUV FAQ, visual observation alone during excavation does not meet the state of the art. Proper specialist explosive ordnance clearance accompanying construction must be distinguished from visual observation alone and requires justified planning.
For ongoing groundworks, investigation areas, access and coordination between site management, contractors and the explosive ordnance specialist company are established before work begins. The risk assessment considers the activities actually proposed and protective measures required. Agree how new findings or changed conditions are communicated and who coordinates the next work steps. Investigation evidence is handed to site management with its spatial and technical scope of validity. If a foundation point, excavation pit or retaining works change, the change is checked against existing results before the intervention concerned. The commissioned specialist task remains distinguishable from general site organisation.
Next steps
What you can prepare for coordination
Compare the project and documents
Use a site plan allowing structural elements and investigated areas to be compared. Add elevation references and depths insofar as established. If this information is missing, identify outstanding points. A clearly identified provisional status is more helpful for processing than an apparently complete but outdated drawing. Initial contact records the approaching construction task. Document assessment compares existing knowledge with the interventions concerned and records information still to be obtained.
Define historical information and methods
Record the date, author and investigation purpose for each document. This overview does not replace the documents but helps allocate them. Particularly across several planning phases, it should be clear whether a report adds to an earlier version or addresses a new task. Unclear contradictions belong in specialist questions. Where historical information remains outstanding, the research and aerial photograph analysis required are planned. Subsequent method selection considers their results, the investigation objective and site conditions.
Investigate and assess results
State the groundworks approaching first. This may be exploratory work as well as the start of a construction section. Clarification required must be coordinated with this step. A later main construction date does not itself make preparatory interventions safe; their prerequisites must be assessed too. The agreed survey or investigation accompanying construction addresses the defined areas under coordinated prerequisites. Survey data and findings are assessed with their limitations. New knowledge is communicated to site management and the parties concerned.
Document results and coordinate the next works
After investigation, site management needs results with their associated plans and conditions. Uninvestigated remaining areas must stay identifiable. If structural elements or depths change, it must be assessed whether earlier findings still apply. Retain the original report so that later decisions remain traceable. The report and site plans document the actual service scope. Using the results, the parties clarify which next groundworks are covered and where further specialist investigation or official coordination is needed.
Documentation
Record the commission, result and responsibilities
Findings and their scope
The final report should show what was commissioned, actually addressed and assessed with which limitation. Reference to a successful test survey is insufficient if construction needs broader findings. Documents should therefore be handed over together with the assessed plan revision.
Project responsibilities
In Rhineland-Palatinate, the state explosive ordnance clearance service supports the competent authorities in preventing specific hazards. Suitable private specialist companies undertake separately commissioned precautionary research and assessment. FONTANA-EOD documents the agreed specialist services; official decisions are made by the respective competent authorities. For federal properties, the BFR KMR form the technical framework; for other projects, they may serve as technical guidance.
Working approach
How FONTANA-EOD works
Document the agreed specialist service clearly
We assess the planned groundworks against the available documents and their design revision. Before attending site, we agree with you what needs to be investigated, which areas are accessible and what findings are required. If the design or site conditions change, we check whether the agreed scope remains appropriate. The report states what was actually investigated and the limits of the findings. This allows designers and site management to see which findings they can use and where questions remain.
Discuss the investigation taskThe task before the equipment
We first establish the investigation objective: which question must it answer? We then select a technically suitable method. The availability of a particular device or experience on a similar neighbouring site is not enough to justify the choice of method on its own.
Keep limitations visible
Inaccessible areas and limited conclusions are identified. They do not disappear into a total area figure. Designers and site management can then decide specifically which areas still need attention and when a suitable survey becomes possible.
Clarify changes before intervening in the ground
A new location, additional depth or different construction method is compared with previous results. A familiar project name does not replace this comparison. Feedback is provided before the affected work so that an outstanding question can be included in the sequence.
Hand over the report and plan together
The technical conclusion remains connected to its location references and appendices. A brief summary helps orientation but does not replace the documented survey scope. This basis is retained even if site management or contractors change.
Understand the results
Use technical statements for the next decision
Interpretability is bound to conditions
The quality of specialist findings also depends on conditions in the area investigated. An assessment is therefore read with the relevant areas and limitations. Transferability to further subareas must be checked. The blanket description suitable leaves this context unclear and should be supplemented by complete documentation.
Understand investigation reports and their limitationsAn older report may support a current decision
Its age alone does not determine its value. Assess its task, spatial reference and changes since then. Usable knowledge can then enter further planning specifically. Original limitations remain in place. New construction plans need a traceable comparison even if several investigation documents already exist.
Understand the service scopeDesign and findings

Historical evidence and the current design
Aerial photograph interpretation is related to the actual groundworks. Its purpose and geographical scope remain distinct from a technical investigation of the ground as it is today.

Process and documentationQuestions from planning
Questions about investigation in Neustadt
Is an earlier test survey sufficient to start construction?
This can be assessed only from the task, results and actual scope. A test survey may examine a method's suitability without covering all later intervention areas. The report must therefore be compared with current construction plans. Clarify investigation needs before the ground interventions proposed first, including preparatory exploratory works.
Why are preliminary investigation and the survey record listed separately?
They address different questions: preliminary investigation assesses historical indications; a technical survey examines the ground using a particular method. For test fields, interpretability of that method may initially be the main focus. The respective report's content is decisive.
Can I use the state garden show site's results for my property?
The reports published there concern the project area described in them. Another property requires separate consideration of its location, existing knowledge and proposed interventions. Proximity to an investigated area does not replace this allocation.
Which documents and official coordination are needed at project start?
The current site plan, proposed ground intervention details and existing reports including appendices are helpful. Tell us if documents are missing or depth is not yet established. The information needed for the next decision can then be discussed. Coordinate the specialist task with the explosive ordnance company and official requirements with the office responsible for the site. The state explosive ordnance clearance service supports authorities with specific hazards.
What should I do if I find possible ordnance?
Stop work in the area concerned. Neither touch nor move the object, move away and keep others away. Notify the police on 110 from a safe distance and follow their instructions.
Why may two test areas receive different assessments?
Site conditions and therefore interpretability may differ. An assessment is therefore read together with the specific field and investigation objective.
Which appendices are particularly important for a test record?
Depictions of the fields investigated and their associated results and limitations. They enable comparison with the current intervention plan.
How does a changed surface affect investigation and costs?
The change is described and compared with earlier test conditions. Specialist planning assesses which knowledge remains usable. Additional areas, depths, interference, accessibility and separate deployments affect the effort required. Precautionary private assessments are commissioned for a fee. Agree the investigation needed and result documents to be handed over for the actual conditions.
