Ordnance assessment in Hesperange
The buildings are constructed on your own property, but access routes and connections may extend into existing roads. For a project in Hesperange, these groundworks should be recorded together. FONTANA-EOD clarifies with you which investigations are already available and which questions remain unresolved at the boundaries.
Show the planned earthworks.
Include work outside the property.
Clarify responsibilities early.
Assess the construction project
How should the property and road connection be prepared together?
Show the groundworks on the property and the complete connection to the existing road. Include working space, depths and any temporary access routes. Assign all participating project owners' reports to the areas they cover. A property or contract boundary does not replace the findings needed for the actual connection area.
Project site
Connect the site with the specific construction task
Relate the Paul Jomé II plans to your own connection
The local example describes connections to existing roads and additional paths outside the development site. For your project, consider the actual ground interventions against the current drawing revision. A PAP boundary does not automatically define the extent of all groundworks. Agree the investigation information needed for areas outside the property itself or an individual construction contract as well.
The municipality of Hesperange lies on the Alzette. The municipal description of the area identifies Luxembourg City to the northwest, Contern to the east, Roeser to the south and Weiler-la-Tour to the southeast as its neighbours. For a connection in the surrounding area, the precise project address and municipality matter. A neighbouring construction project or the same street name does not automatically imply the same authority or transferable investigation results.
For the regional context of your construction project, the Central Luxembourg overview provides further local information.
Local context
Paul Jomé II and the development of connection areas
Infrastructure and paths outside the PAP Paul Jomé II
The explanatory report for the PAP “Paul Jomé II” of April 2024 describes access via the existing Route de Thionville and Allée de la Jeunesse Sacrifiée 1940–1945. No new road is planned within the PAP. The report also considers concurrent renewal of the adjoining roads and a shared pedestrian and cycle path outside the PAP boundary.
Relate historical events to today's groundworks
The plans illustrate why the boundary of a development site need not match the extent of all its associated groundworks. An ordnance assessment must consider the ground interventions actually proposed, even where several parties are involved. The 2024 report describes a plan; it establishes neither full implementation nor ordnance clearance. Current drawings are needed for an enquiry today.
On 26 December 1944, a tank accident occurred in Hesperange. The local Geschichtsfrënn document the event in a dedicated publication. This historical connection with the area must be distinguished from an assessment of ordnance on a particular plot. For a construction project, relate historical findings to the available area-specific records and today's groundworks. The event alone does not justify assuming contamination at the road connection.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For work in the Grand Duchy of Luxembourg, the prerequisites for the specific activity are checked before work begins. Company qualifications and personal credentials are assigned to their respective purposes. The scope of services describes the technical tasks and coordination with the responsible parties. The records identify the notifications or documents required, who handles them and how the clarified status will be made available before work starts.
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.
Local procedure: Municipality of Hesperange: PAP Paul Jomé II, explanatory report 2024 · Municipality of Hesperange: PAP NQ-HS-04b, documents of 22 May 2024.
Planning and documentation: BFR KMR: principles of clearance planning · BFR KMR: geophysics · BFR KMR: documentation · Luxembourg Army: SEDAL
The BFR KMR are used as technical guidance; locally applicable requirements and responsibilities must be clarified separately.
For work in Luxembourg, check the locally applicable requirements for the specific activity before carrying it out. Guidance on temporary cross-border services and the posting of employees is provided by Guichet.lu: service provision and Guichet.lu: posting of employees. The necessary notifications and evidence relate to the type of service and personnel deployment. German technical guidance does not replace these Luxembourg requirements.
Working together
Distinguish the tasks of client, designers and specialist contractor
Client and operator
The project owner describes the project and provides existing records. Operators add information on use, access and timing requirements. A coordinating contact brings the information together. The parties agree their respective tasks and decision responsibilities. Before commissioning, the records identify missing information, who will obtain it and which decision the result is intended to support.
Planning and construction management
The specialist designers describe areas, depths, construction methods and changes. Site management coordinates the planned sequence with the construction contractors and agreed specialist works. Results are assigned to the respective intervention. A technical plan change is communicated early enough for its effect on the survey task to be assessed before construction. Organisational construction stage boundaries remain distinguishable from technical survey boundaries.
Specialist company and competent bodies
The private explosive ordnance specialist carries out the agreed investigation and documentation work within the permitted framework clarified for Luxembourg. The technical report identifies the task, areas actually covered and limitations of the findings. Required notifications and evidence relate to the activity and personnel deployment. The responsible Luxembourg bodies make the decisions assigned to them. The state SEDAL service carries out its responsibilities for found ammunition. The specialist contractor and project participants agree the necessary handovers with the responsible bodies.
Investigation task
Which specialist task comes next?
Relate existing road reports to the new task
Check which areas and depths an earlier investigation actually covered. New connections may fall outside that scope, even within the same street. The technical planners therefore need the complete maps and limits of the findings. Suitable earlier work remains usable; missing information cannot be replaced by a general assumption that a road already in use has been adequately investigated.
Compare the existing investigation scopeClarify measurement conditions at the connection
Utility lines, buried installations and restricted access may affect what can be established. Provide known records of existing conditions and the planned traffic or operating arrangements. Select the method to suit the investigation objective. Keep limitations documented and relate them to the subsequent works so a small area is not left unchecked simply because of its size.
Compare investigation methodsProject types
Coordinate the investigation across property and contract boundaries
Relate historical assessments to the connection areas
Bring together existing aerial photograph analyses and other historical findings for the whole working area, including groundworks outside your own property. Present use as a road does not adequately establish the condition of the ground. Earlier investigations can be used if their geographical coverage and technical findings demonstrably match the new intervention.
For an earlier historical assessment, check whether its coverage includes the connections now needed outside the plot. It may have focused on a former development site while the current contract extends into the existing road. Keep these boundaries visible in the combined site plan for the enquiry. Identify unavailable appendices as missing evidence rather than drawing conclusions from the project title.
Arrange specialist assessment of historical evidence
Determine the technical requirements for each intervention
Show routes, access roads and individual excavations with their depths. The technical planners compare these tasks with existing results and site conditions. The road and property may differ in access or buried installations. Tailor the approach to those conditions; a shared project name does not establish that every part can be investigated in the same way.
Show the connection's actual alignment, including any shaft to one side, the working space needed and groundworks for temporary access. Even if different contractors build these elements, keep them identifiable on a combined site overview. The technical planners can then relate existing results to each part. Changes in depth or position concern the affected location rather than automatically changing the assessment of the whole property.
Compare specialist services
Hand over complete results between the parties
Keep reports available with their maps, depth information and limitations. Site management must be able to identify which report applies to each connection area. Where construction contracts are separate, identify the transitions explicitly. Record unresolved questions against the affected area and clarify them before the corresponding groundworks rather than assuming they are being addressed on another site.
At the handover between the property and road contracts, consider the geographical limits of both services together. Overlapping reports may concern different depths or construction stages. Explicitly identify any unresolved strip between two investigated areas. Agree with the responsible parties who will obtain missing records and who will address the technical question at the connection. Site management receives the relevant results before that stage of work.
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 sound workflow distinguishes work already clarified technically from outstanding prerequisites. If an area will be accessible only in part, commissioning must take this into account. Handover and assessment of results also need time in the construction sequence. An enquiry therefore does not imply a blanket commitment on dates or cost. Specific coordination connects the described scope with access, documents, execution conditions and the date by which a decision is needed.
Discuss the scope and scheduleTasks at the site
Consider the property and road connection together
01
Draw the connection precisely
Show where an access route or utility line leaves the property and connects to existing infrastructure. An arrow ending at the property boundary is insufficient if excavation continues beyond it. The drawing should also show the working space needed. Clarify any uncertain connection positions before the relevant ground intervention.
A connection may lie beyond the development boundary without its full working space being shown in the PAP. The investigation therefore requires the current construction drawing with the actual trench or shaft section. The party responsible for the design identifies the applicable revision and elevation datum. Record unclear distances or formation levels as unresolved information; do not tailor an investigation to assumed geometry.
02
Record the scope of each construction lot
Building construction and roadworks may be awarded separately. The investigation must nevertheless identify who will work in each part of the ground. Match the proposed works to the relevant drawings. Identify overlaps or gaps between construction lots early so unchecked assumptions are not passed on at a connection.
03
Identify the areas covered by existing reports
A report on the construction site does not automatically cover the adjoining road. Check the areas shown, investigation depths and limitations. An earlier road investigation must also match the new intervention. Proximity to the project alone is insufficient to use its results for a new trench.
Earlier roadworks and the new private connection may involve different depths. Review the old report together with its site plans and depth information. Road width or a continuous surface does not replace this evidence. If the connection moves from its earlier planned position, provide the specialist contractor with the revised position and working areas affected. Applicable results remain usable; further work addresses the question that actually remains unresolved.
04
Include temporary access routes
Temporary access may require additional groundworks, for example to construct the access or its connection. Where proposed, describe these interventions by position and depth. A short period of use alone does not answer the ordnance question. Distinguish use of existing paved areas from physical alterations to them.
Project documents
Documents that establish the next step
Show working space beyond the boundary
A connection may extend beyond the plot boundary into the road structure. Draw the complete alignment and proposed working areas. An arrow ending at the boundary is insufficient for this comparison. If the precise connection position remains unresolved, account for that during preparation and agree it with the technical planners before the relevant intervention.
Where clearance work has been carried out, a clearance record documents the commission, areas actually worked, methods, positional and depth references, findings, limitations and outstanding tasks. Hand over the accompanying drawings together. Where property and road contracts are separate, these records identify which conclusions apply to the connection and where further technical work is needed.
Assess temporary access by the ground intervention it requires
Distinguish use of an existing surface from alterations to it. If additional groundworks are needed, include their positions and depths in the enquiry. A short period of use does not determine the technical requirements. Check early works against the available findings before carrying them out for the later main construction phase.
For temporary access, specify whether an existing paved area will simply be used or whether ground will be broken, excavated or altered. Include ancillary works with their positions and depths in the preparation. Temporary use replaces neither a review of existing findings nor the necessary coordination. The responsible parties address traffic arrangements, access rights and ordnance assessment separately; an investigation alone does not authorise roadworks.
Construction sequence
Coordinate investigation and construction sections
Use a combined site plan for the enquiry
Bring the property, connections and additional working areas together on one plan. Include detail drawings with their applicable revisions. Provide the reports available from all parties and identify missing records. Initial coordination can then identify geographical gaps or overlaps and establish the further technical work needed for the actual next stage.
Schedule handover before construction phases change
Clarify which results the next contractor needs and who will supply them. Compare changes in position or depth with the documented scope. Site management receives the complete appendices before the affected work. Applicable findings can continue to be used while unresolved connection areas remain linked to a specific task and responsible party.
Method selection
Select methods according to the task and survey conditions
Historical records and aerial photographs
Geomagnetic surveying records disturbances in the Earth's magnetic field, which may be caused by ferromagnetic objects, among other sources. At a road edge, utility lines, installations and neighbouring structures can affect measurements. A measurement arrangement suitable on private land cannot therefore be transferred to the connection in the road without checking it. Establish the investigation objective and what can actually be assessed for both parts.
Understand aerial photograph assessmentMagnetometric survey
Electromagnetic methods can respond to metal objects. At a connection between a property and road, compare the areas and depths to be investigated with the existing installations. Measurement conditions can change over a short distance. Recorded signals require specialist interpretation; margins that cannot be investigated remain identifiable in the results.
Understand the scope of magnetometryElectromagnetic methods
Ground-penetrating radar uses electromagnetic reflections to investigate underground structures. Its contribution to a specific ordnance question depends, among other factors, on soil structure, moisture and conductivity. As-built plans for a road connection help identify features but do not prove the actual position of every installation. Agree the investigation against the findings needed and local conditions; it does not replace a separate assessment of utilities or structures.
Understand electromagnetic surveyingGround-penetrating radar
Borehole methods may be considered for deeper investigations. For a shaft or connection, relate measurement positions and the required coverage to the planned intervention and its elevation datum. Shallower investigations nearby do not automatically cover this volume of ground. Creating access for an investigation is itself a ground intervention: clarify its prerequisites and coordination with existing utility lines before starting.
GPR and limitationsDeep-ground and downhole surveys
A properly prepared investigation alongside construction is tailored to the actual construction stages and a suitable investigation objective. Presence on site alone does not replace an investigation required beforehand. If property and road works are commissioned separately, the investigated sections, unresolved margins and handover to the next contractor must remain traceable. Agree protective measures and procedures for anomalies with the responsible parties before work starts.
Prepare deep interventionsSurvey during construction
Specialist interpretation relates measurement data and findings to the investigation objective, positional reference and actual measurement conditions. At a road connection, identify where the documented conclusions end and which part still needs work. The report and accompanying drawings record elevation and depth references, interference and limitations. Site management and technical planners can then relate the results to the planned stage and the responsible contract.
Agree the approach during constructionTechnical assessment
Which investigation can answer the unresolved question
Clarify the historical evidence
A historical aerial photograph analysis can supplement existing findings and help assess the proposed construction site. Its geographical coverage should also include the affected connection areas. Present road use does not establish a conclusive assessment of the ground below. Include available earlier investigations in the initial coordination.
Account for measurement conditions at the road
For surveying, area and the intended investigation depth are not the only considerations. Utility lines, installations, access and other interference can limit what can be established. These conditions must be known before selecting a method. Explicitly identify areas that cannot be assessed adequately in the results so they can be accounted for in subsequent planning.
Fit investigations into the construction sequence
A clearance plan can establish which technical prerequisites must be met before each ground intervention. It must also account for handovers between property and road construction. Observation of later excavation cannot replace a required preliminary investigation. Agree the approach for the specific project and Luxembourg requirements.
Next steps
From a combined site plan to investigation and handover
Use one site plan for all affected areas
Bring the property, connections and any temporary working areas together on a combined plan. Existing detail drawings may be included. Their positions and revisions must be traceable. An overview helps coordination but does not replace necessary details for individual components. At first contact, clarify the project location and the technical findings needed. Check existing drawings, statements and investigation reports for currency, geographical relevance, completeness and gaps.
Address outstanding historical questions
Where historical questions remain unresolved, the source research and aerial photograph analyses required are actually carried out within the agreed commission. Results are assigned to today’s parcels and ground works areas. Existing assessments retain their identifiable scope; new findings inform investigation planning.
Include depths and construction stages
Specify proposed formation levels, working space and the sequence of interventions. If an exact depth has not yet been determined, make that uncertainty clear. Investigation planning differs depending on whether only an upper layer will be altered or a new, deeper connection constructed.
Obtain reports from the project owners involved
Request the complete investigation records for neighbouring working areas. Summaries without positional and depth references are often insufficient for a reliable comparison. Record which documents are available and who must still supply others. Do not replace missing results with the assumption that everything has been clarified on the other site. Select the method against the investigation objective, planned interventions and actual ground and measurement conditions. Agree access, protective measures and coordination between the works with the responsible parties.
Perform the agreed investigation
The agreed survey or professional investigation during construction is carried out in the defined areas and at the defined points. Measurement data and observations are assigned to the location and vertical reference used. Departures from the planned investigation areas, sections not covered and relevant interference are recorded.
Assess and document findings
The measurement data and findings collected are assessed professionally against the investigation objective and actual conditions. The report and associated plans document the areas covered, location, elevation and depth references, interference and limitations. Outstanding tasks are assigned spatially so that the next decision can relate to the work step concerned.
Pass on design changes at the connection
If a route or access moves after the investigation, compare the revised intervention with the documented result. The same applies if the works go deeper. Inform technical planners and site management before the affected works so they can assess the significance of the change and clarify any further investigation needed. Hand over the report and drawings with the areas covered, limitations and outstanding tasks. Agree the decision needed for the next intervention with the responsible parties.
Documentation
Technical project coordination and reporting finds
Findings and their scope
For your enquiry in Hesperange, we consider the available information and planned groundworks together. Whether FONTANA-EOD can undertake services, and to what extent, is clarified for the specific project, including the necessary local coordination. The result of a private investigation must be distinguished from official decisions and other prerequisites for construction.
Project responsibilities
In Luxembourg, SEDAL performs public duties such as identifying, neutralising and destroying found ammunition. An enquiry about a construction project does not replace immediate reporting of a suspicious object. Do not touch or move it. From a safe distance, notify the police on 113 or SEDAL.
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
Assign responsibility for records clearly
Identify who will obtain earlier reports for the property and road and who will pass on design changes. Keep missing appendices recorded as outstanding tasks. The technical planners can then base their conclusions on traceable information. An assurance that another party has already considered the area does not replace a suitable report with an identifiable geographical and technical scope.
Understand investigation reports and their limitationsShare connection changes with all parties
A relocated shaft or deeper route may affect several contracts. Pass on the revised design before the relevant works. Relate existing results specifically to that change. Site management should be able to see which conclusions remain valid and what further work is needed, without discarding complete, suitable earlier work because of a localised change.
Understand the service scopeDesign and findings

Process and documentationQuestions from planning
Questions about work at the property boundary
Does an investigation of the construction plot cover the road connection?
Only if the existing report actually covers the proposed connection area and relevant depth. The property boundary alone does not determine the investigation scope. Compare the complete intervention with the geographical limits and restrictions of the result.
Does a PAP with no new road mean no assessment is needed outside it?
No. Connections to existing roads may also involve groundworks outside the development site. Whether these require further ordnance investigation depends on the interventions and existing findings. The type of access arrangement does not replace that comparison.
Must two project owners have the same area investigated twice?
Different project owners do not, by themselves, make duplicate investigation necessary. Existing results can be considered if they are available, traceable and suitable for the specific work. Area, depth, investigation objective and documented limitations remain the deciding factors.
Which version of the Paul Jomé II records is needed?
For a project today, the drawings currently in use and existing investigation reports are decisive. The April 2024 report cited here explains the plans at that time. The municipality provides various documents on its PAP page; clarify how they relate to the actual construction stage.
What should you do if a suspicious object is found in a trench?
Stop the affected work. Do not touch, move or relocate the suspicious object, or expose it further. Leave the danger area and keep others away. From a safe distance, notify the Luxembourg police on 113 or SEDAL. Do not take the object to a police station or other official premises, or to a recycling centre. Follow the instructions of the responsible authorities.
Why is an arrow ending at the property boundary insufficient?
Because the actual connection may extend further into the road. Its complete alignment, working space and depths must be identifiable.
What affects the cost of explosive ordnance assessment?
The work involved depends on the specific question, existing findings and agreed investigation scope. Describe the property, road connection, required depths and access together. Utility lines or other interference may affect the works. The quotation assigns the necessary research, field investigation, interpretation and documentation to the relevant areas. Agree additional tasks arising from a relocated connection or margins that initially cannot be investigated separately.
What should an enquiry about temporary access include?
The groundworks actually proposed, with their positions, depths and dates. Distinguish use of existing areas from physical alterations.
Project enquiry
Prepare the first technical discussion
Draw the connections
Send a combined site plan for the property in Hesperange and the adjoining road connections. Identify working spaces, trenches, shafts and temporary access with their proposed depths and elevation datum. Specify the separately commissioned construction services and the first section to be carried out. The available reports provide a basis for discussing which results already cover the groundworks and which investigation is needed before the next intervention.
Obtain the records together
Include existing investigation reports in full, with accompanying drawings and limitations. Assign each report to the property, road area or connection and record the applicable drawing revision. Identify missing records and unclear transitions as specific questions. State who will bring together the records from the project owners or contractors involved. This allows the scope of services, outstanding technical tasks and handover of results to be agreed before the respective groundworks.
