Explosive ordnance surveying in Wolfenbüttel
Boreholes and trial pits for geotechnical investigation already disturb the ground. Therefore clarify which explosive ordnance investigations are necessary before this work. FONTANA-EOD checks the ground investigation programme with you for your project in Wolfenbüttel and investigates the affected areas and depths within the agreed scope.
Compile positions, methods and planned depths.
Clarify necessary investigations in good time.
Compare changes with existing results.
Assess the construction project
Clarify the explosive ordnance question before the planned ground investigations
Boreholes, trial pits and preliminary working areas may disturb the ground before construction itself. For your project in Wolfenbüttel, we compare the investigation programme with existing explosive ordnance documents. Required results are provided before the respective interventions and assigned unambiguously.
Project site
Connect the site with the specific construction task
Clearly identify investigation areas in Wolfenbüttel
Wolfenbüttel is in the district of the same name in Lower Saxony. The Braunschweig administrative area provides regional orientation. For your project, specify the address, land parcels and affected ground investigation points. Existing information and investigation reports are assigned to this area. Local responsibility is determined from the specific municipality. Planned investigation stages, preliminary groundworks and programme changes are agreed with the respective responsible parties.
Local context
Clarify the explosive ordnance question before geotechnical investigation
Sequence of specialist investigations
Clarify the explosive ordnance question before geotechnical investigation disturbs the ground. Describe the position and depth of planned boreholes, probes or trial pits. Geotechnical investigation addresses different questions from explosive ordnance assessment. Coordinate the sequence of both investigations.
For Fümmelse, the City of Wolfenbüttel describes construction of an anti-aircraft position in 1943 to protect the neighbouring Reichswerke. In Wendessen, an air raid in January 1944 destroyed the church and adjoining manor. For properties near such former positions and destroyed buildings, the land-use boundaries at that time are compared with present construction areas. Maps, aerial photographs and building files help assign military areas and later demolition and reconstruction conditions spatially.
Preliminary geotechnical investigation at Södeweg
In the explanatory statement for development plan IX “Am Södeweg”, the City of Wolfenbüttel describes a preliminary geotechnical investigation from 2016, extended in 2017. The planned roundabout on Ahlumer Straße was also included. These investigations, attributed to engineering consultancy BGA, concern ground and groundwater conditions. An explosive ordnance investigation report independently answers the question commissioned for it. For your project, both document types are assigned according to their respective purpose, date and investigation area.
Different recommendations for individual areas
The LGLN statement dated 5 December 2018, published with development plan VL “Am Ahlumer Wege”, gives different recommendations for three areas: aerial photograph assessment for one, surveying after aerial photograph assessment for another, and no action needed at that time for a third. According to the documented status, no surveying or clearance had yet been carried out for these areas. Their associated maps and the findings available at the time form part of these statements. Current planning also checks later investigation reports and project changes. The recommendation for each area is compared spatially with the planned ground investigation points.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For commissioned activities in Germany, the relevant specialist requirements and questions of permits, competence and responsibility are clarified. The scope of services actually planned is decisive. When searching for munitions that have been found, the scope of § 1b of the Explosives Act is considered. For relevant commercial activities, the permit under § 7 and the competence of responsible persons under § 20 are related to the specific task. The commission, allocation of tasks and required qualifications are recorded clearly before execution.
Link occupational safety to the construction sequence
The risk assessment, work areas and communication must suit the planned activities. Specialist explosive ordnance work is coordinated with other construction work. Operational organisation, site and traffic safety, and other technical specialist assessments retain their own responsible parties. Joint coordination brings the necessary information and respective responsible people together.
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.
Assign the recommendations from the LGLN statement on Ahlumer Wege dated December 2018 to the associated areas and present-day interventions. The explanatory statement for development plan IX “Am Södeweg” and the geotechnical report published in 2017 document the geotechnical basis at that time. For explosive ordnance, the tasks of the competent authorities are related to existing findings and the planned investigation.
Within their federal scope, the BFR Kampfmittelräumung describe principles for clearance planning, geophysics and documentation. The DGUV FAQs on explosive ordnance clearance explain questions concerning specialist and safe execution. For the project file, the investigation objective, work actually carried out, result and plan appendices are linked traceably.
The BFR KMR are used as technical guidance; locally applicable requirements and responsibilities must be clarified separately.
Permits, competence and responsibility for the specific activity are considered under the Explosives Act and the First Ordinance to the Explosives Act. The risk assessment in Germany under Section 5 of the Occupational Safety and Health Act relates to the planned activities. The DGUV Information 201-027 covers preventive investigation and clearance of conventional explosive ordnance and defines its scope. Its references to DGUV Rule 113-003 concern particular activities involving explosives; they are not applied indiscriminately to every construction-site investigation.
Working together
Distinguish the tasks of client, designers and specialist contractor
Client and operator
The project owner describes the project and provides the existing project documents. The operator adds requirements for use, access and timing. Project participants agree their respective tasks and decision responsibilities. Before commissioning, record which information is missing, who obtains it and which decision the result is intended to support.
Planning and construction management
The specialist designers describe areas, depths, construction methods and changes. Site management coordinates the planned sequence with the construction contractors and agreed specialist works. Results are assigned to the respective intervention. A technical plan change is communicated early enough for its effect on the survey task to be assessed before construction. Organisational construction stage boundaries remain distinguishable from technical survey boundaries.
Specialist company and competent bodies
The private explosive ordnance specialist company carries out the agreed investigation and documentation scope. Official requirements and decisions are clarified with the respective competent authorities. Which documents are needed for a specific procedure depends on the location and project. The technical report documents the specialist work carried out, with areas, depths and limitations. Its applicability to further groundworks is compared with the specific intervention. Official decisions are made by the competent authorities.
For projects within Wolfenbüttel, local hazard response is coordinated with the city. For a location in the surrounding area, the respective municipality is determined from the project address. The LGLN’s state explosive ordnance disposal service carries out its state responsibilities and supports the competent authorities. Specialist commissioning and necessary official coordination are brought together in the project sequence.
Investigation task
Which specialist task comes next?
Compare results areas with the ground investigation programme
Existing aerial photograph assessments are read with their maps and recommendations. The starting situation for one planned point may differ from the next. Also consider later technical reports and their limitations. This comparison shows which positions have been assessed sufficiently and which areas need further specialist clarification before intervention.
Assess historical documentsKeep the investigation objective distinct from the geotechnical method
The geotechnical method defines its own ground-related task. The preceding specialist explosive ordnance work depends on its investigation objectives and local conditions. Position and depth of the planned ground investigation points are important information for this. They do not alone justify a particular explosive ordnance method or guaranteed range. The specialist planners describe a suitable scope for the areas affected.
Compare investigation methodsProject types
Describe ground investigations and preliminary work in full
An investigation programme with several positions
For each planned borehole or probing position, specify location, depth and method. Specialist explosive ordnance planning compares these points with existing assessments and reports. Different results for individual areas remain identifiable. A shared project name or regular point grid does not describe a uniform investigation status. Positions still unresolved are explicitly marked so that their later definition can be agreed with specialists.
Assign each proposed borehole an unambiguous point number and current plan version. The enquiry includes the planned final depth, relevant ground surface and proposed investigation method. Distinguish defined points from possible alternative positions. If a position moves later, it remains clear which original point was replaced and whether an investigation result already exists for it. The agreed current point layout is provided to the geotechnical company carrying out the work. Additional questions about position or the depth range considered are clarified before the respective intervention.
Understand downhole surveys
Trial pits with additional working space
A trial pit occupies an area and may require preliminary work extending beyond a single point location. Describe the proposed dimensions, depths and access. Include necessary exploratory openings or exposure work and their sequence. The explosive ordnance question is clarified before these interventions. The geotechnical investigation subsequently addresses its own specialist task within the planned programme.
A trial pit may need additional working areas beside its opening. Therefore also describe whether an access route must be built for the equipment, paving opened or a working area prepared. These first groundworks may precede the geotechnical investigation point. Planning assigns the prerequisites and investigations needed to them. If the extent or depth remains unresolved, state this explicitly. Joint coordination between the client, geotechnical planners and explosive ordnance specialist company concerns the actual work area and its intended construction condition.
Provide specialist supervision of excavation
Extended investigation at new connections
If an access road, road connection or further construction areas are added to the programme, new ground volumes may be affected. Enter the additional investigation points and preliminary work on the current plan. Existing results remain usable insofar as they actually cover the extension. For points and depths beyond this, identify specifically which further findings are needed before execution.
If the investigation programme is extended, a change register and shared site plan help. Distinguish new investigation points, removed points and additional investigations at access roads or connections. Existing results retain their documented scope. Specialist review establishes which new positions it includes and which tasks need further information. Also identify the reason for the extension, such as a changed building arrangement or additional development works. This gives the next commission a traceable spatial basis.
Specialist services and investigation tasksPreparation
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 reliable sequence distinguishes work whose specialist requirements have already been clarified from prerequisites still unresolved. If an area will be only partly accessible, this is considered when commissioning. Handover and assessment of results also need time within the construction sequence. Scope, timing and the work involved are agreed for the specific investigation programme. Access, preliminary work and necessary decisions are coordinated together.
Discuss the scope and scheduleTasks at the site
Work included in the ground investigation programme
01
Boreholes and probing points
For planned ground investigations, compile the individual positions, proposed intervention and required depth. Points not yet defined remain visibly unresolved. Mark the proposed work area precisely enough for the investigation to be planned around it.
02
Trial pits and exploratory openings
If ground areas are to be opened, their dimensions and planned work stages form part of coordination. Preliminary exposure work may also be relevant to explosive ordnance. Clarify the prerequisites for this exposure work before execution.
03
Access routes and equipment standing areas
If an access route must be constructed for investigation equipment or a working area prepared through ground interventions, this area is considered additionally. The investigation commission must then cover more than the actual investigation points. State whether existing areas will merely be used or groundworks are planned there.
04
Additional investigation areas
If a road connection, new alignment or further construction areas are added to the programme, compare the additional interventions separately. Previous documents remain usable where applicable. Check whether the previous investigation scope includes the additional areas.
Project documents
Documents that establish the next step
Identify ground investigation points consistently in all documents
Use unambiguous identifiers for the proposed positions and keep position, depth and plan version together. The associated explosive ordnance documents and geotechnical programme must be spatially comparable. If a position changes, all participants should be able to identify this. A number alone is insufficient without an associated current spatial reference.
Hand over results according to each specialist task
The explosive ordnance report and geotechnical report each contain the results of their own investigation. At handover, the commission, methods and limitations remain unambiguously assigned. For the explosive ordnance task, measurement data, survey results and assessment of findings remain linked to the site plan and report. After clearance work has been carried out, the clearance record, with its scope, results and remaining limitations, supplements these documents for the points actually investigated. Before its ground intervention, the specialist company carrying out the work receives the documents needed. Unresolved assessments are recorded with a responsible person rather than hidden in a general statement about the overall project.
Construction sequence
Coordinate investigation and construction sections
Before investigation equipment reaches its position
Creating access or an equipment standing area may also require groundworks. Clarify whether an existing area will merely be used or first altered. The investigation sequence considers these early interventions. Necessary access, documents and specialist results are coordinated so that preparation for the ground investigation itself can proceed on a traceable basis.
If further ground investigation points are added
Additions are passed to the specialist planners with the dated site plan and proposed depths. The new points are then compared with the existing investigation scope. An extension does not automatically require repetition of all earlier work. The decisive question remains which findings are still missing for the additional areas and when they must be available before those areas are investigated.
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.
With transient electromagnetic methods, or TDEM, the time-dependent electromagnetic response of conductive objects is evaluated. Application and signal interpretation depend on the investigation task and conditions in the planned measurement area.
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 preliminary investigation cannot be completed, the specialists assess whether a planned approach during construction is suitable. This includes coordinated investigation, interpretation and communication of findings within the intended work sequence. Visual observation of excavated material is not an interchangeable substitute for a necessary survey. Site management needs a clear description of when specialist work will take place, how new findings will be handled and which areas remain unresolved.
Agree the approach during constructionTechnical assessment
Check geotechnical and explosive ordnance reports separately
Existing aerial photograph assessment
An existing aerial-photo analysis must be checked with its results area and stated limitations. It may provide indications for further planning. Whether it sufficiently addresses the proposed intervention or additional investigations are necessary must be assessed against the specific site and applicable requirements.
To compare it with a ground investigation programme, the aerial photograph assessment’s results area is assigned to the current site plan. Keep the complete report and maps together. Identify which areas have already been assessed and where historical evidence remains unresolved or limited. If different plan versions exist, clarify their spatial relationship traceably. An earlier project name or similar property identifier alone is insufficient. The specialist planners receive the assigned information to decide on the next investigations.
Purpose of explosive ordnance surveying
For any necessary surveying, the task, site conditions and limitations of the proposed method are recorded. The positions of geotechnical investigation points help spatial assignment. Their positions alone establish neither a particular measurement method nor a guaranteed investigation depth.
Define the question an explosive ordnance investigation should answer before geotechnical work. The proposed ground investigation points provide position, depth and working method; actual measurement conditions are also considered. These include existing installations, accessible areas and possible interference. Conditions not yet clarified are identified in the enquiry. Method selection relates this information to the investigation objective. If points are moved or additional depths planned, the effect on the agreed investigation scope is checked.
Investigation before groundworks
The project process must link the necessary explosive ordnance investigation with the subsequent geotechnical work. According to the DGUV, visual observation during earthworks alone does not replace a suitable approach. The measures actually needed are explained on specialist grounds and agreed before the affected work.
For handover to the ground investigation company, the report and plan appendices are provided as a coherent set. They should identify the points or areas actually investigated and remaining limitations. A point list merely marked “checked” often leaves this assignment unclear. Where results are provided in stages, also describe the next intervention being prepared and the tasks still outstanding. Changes after investigation are communicated to the responsible parties so that they can check applicability of the documents before the affected work.
Next steps
From the project enquiry to results handover
Provide plans and the ground investigation programme
Provide the site plan, ground investigation programme and existing explosive ordnance documents together. The documents should identify the property and individual areas affected. Clarify missing intervention details before defining the commission. For initial contact, add the project address, a contact person and the first planned groundworks. We check existing reports and plan appendices for their version, spatial assignment, limitations and unresolved information.
Record work preceding the ground investigation
Identify work intended before the investigation equipment starts its actual task. This may include planned exploratory openings or creation of a working area. Consider this work in the sequence of necessary investigations. If historical findings remain unresolved after document review, the required sources are researched and available wartime aerial photographs assessed. Results are assigned to present-day intervention areas and ground investigation points and incorporated into further investigation planning.
Record commissions and responsibilities
Record who commissions each investigation and which documents are handed to the contractor. The commissions describe the explosive ordnance investigation and geotechnical investigation tasks separately. Official decisions are made by the competent authorities. Suitable methods for specialist work are selected according to the investigation objective, expected objects, ground conditions, interference and accessible areas.
Carry out investigation in areas and at points
The commissioned survey or investigation during construction is carried out in the agreed areas and at the agreed points. Measurement data and observations are recorded with their horizontal and elevation references. Areas not investigated, restricted access and relevant interference are documented.
Assess survey data and findings professionally
The data and findings collected are evaluated against the investigation objective. Specialist assessment considers interference, the areas reached and remaining limitations. This identifies the further clarification or work needed before the planned intervention.
Hand over the report and plan appendices
The report and associated plans document the specialist work carried out and its assessment. Points or areas investigated, investigation depths, relevant ground surface and limitations remain assigned. The agreed recipients receive the associated documents together for the project file, site management and subsequent geotechnical investigation.
Compare changes and the next ground investigation points
A relocated investigation point or additional investigation depth is compared with previous results before execution. Not every change automatically constitutes a new overall commission. What matters is whether it exceeds the documented area, depth or specialist conclusion. Using the results, the client, planners and site management clarify which work has been prepared within the documented scope and which supplementary investigations or coordination are needed before the next intervention.
Documentation
What an explosive ordnance report must document
Findings and their scope
The report must identify which positions or areas were investigated for explosive ordnance and what conclusions can be reached for them. Plan appendices, methods, limitations and unresolved areas form part of handover. A geotechnical report that contains no explosive ordnance investigation does not replace this evidence.
Project responsibilities
The BFR Kampfmittelräumung describes specialist planning and documentation within its federal scope. For other projects, these principles provide specialist guidance; project-specific requirements must additionally be agreed. In Lower Saxony, statutory municipal tasks and the KBD’s state tasks remain separate from the commissioned company services.
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
Read a geotechnical report according to its investigation question
Geotechnical investigations may concern ground composition, bearing capacity or other ground-related questions. Whether an explosive ordnance investigation additionally exists is checked using the corresponding separate documents. Specialist reports are used for their respective purposes. Keeping them together facilitates planning but does not turn a result concerning ground conditions into evidence of specialist explosive ordnance investigation at the proposed points.
Understand investigation reports and their limitationsDistinguish a recommendation from a measure carried out
A recommendation describes a further clarification step. Whether it has since been carried out and what result follows must be established by the associated report. Later documents are therefore also obtained during preparation. Results areas remain individually assigned so that a conclusion for one area is not applied without checking to every ground investigation point in the programme.
Understand the service scopeDesign and findings
Documents for the next construction decision
Historical evidence and the current design
Aerial photograph interpretation is related to the actual groundworks. Its purpose and geographical scope remain distinct from a technical investigation of the ground as it is today.
Understand aerial photograph assessment
Specialist reports for site management
The findings, their locations and limitations are handed over together. This makes clear to those carrying out the work which area has been investigated and which task remains outstanding.

Preparation connects the commission, site work and handover of findings. Changes to the project can then be incorporated into technical coordination in good time.
Process and documentationQuestions from planning
Questions about construction preparation in Wolfenbüttel
When must the explosive ordnance question be clarified before geotechnical investigation?
Clarify the prerequisites before the investigation disturbs the ground. Necessary measures depend on existing findings, the planned task and applicable requirements. No single investigation method is prescribed for every geotechnical investigation.
Is a geotechnical report also explosive ordnance evidence?
A geotechnical report answers the ground-related questions investigated within it. For explosive ordnance, check whether corresponding separate investigations are documented and whether they cover the proposed intervention spatially and in their specialist scope.
What should be done if a drilling position moves?
The new position is compared with existing investigation areas and limitations of conclusions. If it lies outside the area investigated or depth and working method change, supplementary specialist clarification may be necessary. The change should be agreed before the intervention.
Which documents help with the first enquiry?
A legible site plan, proposed ground investigation programme and existing explosive ordnance reports with their appendices are helpful. Also identify necessary preliminary groundworks. Mark positions or depths not yet defined. Include official requirements too. The competent local authority and state explosive ordnance disposal service are involved according to their responsibilities.
What should I do if a suspicious object is found during work?
Stop the affected work, do not touch or move the object and keep your distance. Keep other people away and notify the police immediately on 110. Follow official instructions; do not investigate, attempt to deal with or transport the object yourself.
How are alternative positions not yet defined addressed?
Identify them in the design as unresolved or as a proposed alternative area. Before actual execution, compare the chosen position with the existing investigation results. A result for another point applies only insofar as its documented scope actually includes the new position and depth.
Must access for the investigation equipment be considered separately?
Describe whether it will merely be used or constructed through groundworks. Proposed interventions are included in preparation with their position and depth. The specialist prerequisites for this work must be clarified before execution, even if the actual ground investigation points follow later.
What determines the work involved before geotechnical investigation?
The position and number of points, required depths, existing explosive ordnance documents and working conditions are essential. Access, preliminary work and timing coordination with the geotechnical specialist company also matter. A complete investigation programme enables a traceable comparison of the required scope.
Project enquiry
Explosive ordnance assessment before your geotechnical investigation
Compile ground investigation points and preliminary work
Provide the site plan and investigation programme with point identifiers, methods and depths. Add trial pits, exploratory openings and preliminary working areas. Positions still unresolved are marked. Existing explosive ordnance documents should include their complete maps and appendices. Also state which earthworks are intended to start first and which areas remain inaccessible. Necessary preliminary work and the results handover can then be coordinated in good time.
Prepare specialist handovers
Identify the responsible geotechnical planners, contractor and project coordinator. State which results are needed before each intervention. Known access restrictions and possible programme extensions help prepare the investigation appropriately. Identify the project address and land parcels, together with the relevant construction and scheduling status. Service plans and as-built plans help assign work areas.

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.
