Briefly explained
A planned project question or an immediate find?
For a planned investigation, available evidence, construction activity and results needed take priority. If an object may be dangerous, protecting people takes priority: stop work at the find location, do not touch, move or uncover anything further, keep your distance and warn others without putting yourself at risk. Notify the police immediately: 110 in Germany, 113 in Luxembourg.

Before construction begins
Suspicion and preparation
Where does clarification of suspected explosive ordnance begin?
With existing indications and investigations for the affected area and the proposed interventions. Historical evidence, available official information, reports and construction design are assessed together. This establishes the specific investigation question. Also assign indications from neighbouring properties with find location, date and available source. Such an indication is assessed by specialists in relation to your construction site; the project name alone does not determine further investigation. For a property purchase, existing evidence is compared with intended use. Rubble and debris layers and unusual ground findings are also assessed as possible indications; on their own, they do not establish explosive ordnance contamination.
Which documents help with an initial enquiry?
Project location, site plan, construction activity and proposed depths help, along with available official information and complete investigation reports. Ground investigation and contaminated land information may explain working conditions. State the plan version, known authority conditions, missing appendices and next planned work step. Information may remain unresolved for initial coordination: identify it explicitly so that additional document needs can be clarified specifically.
Does a railway line or former industrial site automatically make an area suspect?
A railway line or former industrial use alone does not establish explosive ordnance contamination. Infrastructure could, however, have been a wartime target or affected area; earlier military uses may provide further indications. Reliable sources and their specialist assignment to the project location are decisive. Ammunition-related use, a historical attack and ordinary commercial use are considered in their respective contexts. Planning thus receives a supported starting point for further clarification.
Does an existing investigation also apply after a design change?
Insofar as the documented investigation actually covers the new intervention. Compare location, depth, construction method, proposed use and limitations. Include additional working areas and changed ground surfaces. A depth value must match the stated reference level. Mark changes on the current plan; specialists can then assess which part of the existing record remains usable and where additional work is required.
How are existing utilities and inaccessible areas considered?
Provide available utility plans, known infrastructure and access restrictions and mark the affected areas. This information informs measurement planning, occupational safety and execution coordination. Technical interference or lack of access may limit the assessment spatially. Explosive ordnance investigation and clarification of existing utilities serve different tasks; expressly agree the services needed. Results must distinguish investigated areas, areas with limited assessability and unresolved areas.
How are official information and responsibilities clarified before commissioning?
Start with the project location, property and existing official correspondence. Clarify with the parties who will obtain necessary information, submit applications and pass on changes. A private specialist company can provide the agreed technical support; responsible authorities make official decisions. Also record the recipient and purpose of expected records. Procedure and possible fees depend on local arrangements and the specific commission.
Investigation and interpretation
Methods and assessment limits
Does a measurement anomaly already mean an explosive ordnance find?
A measurement anomaly is initially a finding requiring interpretation. Measurement signals may come from existing infrastructure, scrap or other structures, for example. Interpretation considers method, spatial pattern, location and surroundings. Specialists justify which anomalies need further clarification and what assessment is possible for the investigated area. Confirmed identification of ordnance is a different level of evidence from an anomalous measurement signal.
Is ground-penetrating radar fundamentally better than magnetometry?
Suitability depends on the investigation task. Magnetic methods detect changes in the magnetic field; ground-penetrating radar uses transmitted electromagnetic waves and their reflections. Under suitable conditions, radar can image layers and structures; magnetic methods respond particularly to ferromagnetic objects. Target objects, ground conditions, technical interference and the assessment needed determine selection and possible combination. For track or route structures, existing infrastructure and accessibility are explicitly considered.
To what depth can a survey provide meaningful results?
The assessment extends to the depth technically justified and documented for the specific task. Target objects, ground conditions, interference and measurement geometry are decisive. Distinguish investigation depth from a general equipment range. Make the elevation reference clear in the report: after excavation or filling, a depth below the former ground surface may lie at a different level from the same number below today's ground.
Is observing excavator spoil a survey during construction?
An explosive ordnance survey during construction includes suitable technical surveying, qualified personnel and a defined procedure. Visual observation of excavation alone does not meet this technical definition according to DGUV. Clarify measurement equipment, proposed investigation steps and documentation before commissioning. This includes coordination with construction progress, accessible working areas and prerequisites for each next intervention. The agreed sequence must remain identifiable in execution and records.
Reports and handovers
Use results for the construction decision
What must a usable investigation report show?
The task, area actually investigated, method and results must be traceable together. This includes unambiguous horizontal and elevation references, interpretation, plan legend, limitations and unresolved issues. Report and plan appendices are read together. An investigation report describes the investigation performed; a clearance record relates to the corresponding clearance service. Site management must be able to identify which assessment concerns which volume and which subsequent decision it can support.
Is a clearance statement a promise of absolute freedom from explosive ordnance?
Read a clearance statement against the documented clearance objective, area and depth treated and methods used. It describes a defined service and assessment scope. Markings for untreated zones or limited measurability form part of it. Compare this scope with your next intervention. The assessment for a section can technically be used only within evidenced limits; neighbouring areas, greater depths or changed use require their own comparison.
Can a project be undertaken in construction sections?
Yes, if areas, interventions, investigation tasks and handovers are defined unambiguously. Each section needs a traceable work and decision status. Also identify additional working areas, such as site roads, storage or site facilities, insofar as ground interventions are proposed there. Site management must be able to identify which areas have been assessed for which work and which remain unresolved. Phasing is therefore connected with specialist assessment and handover points.
What is the purpose of a clearance plan?
A clearance plan connects existing evidence and construction design with the intended clearance objective. It describes affected areas, suitable methods, scope, sequence, interfaces and responsibilities. Area clearance must also consider local obstacles and different intervention depths. The detail required in planning depends on the task and applicable requirements. For commissioning, the intended result and its documentation are identified unambiguously.
If an item is found
What to do when explosive ordnance is found
What should be done first if an object may be dangerous?
Stop work at the find location, do not touch, move or uncover anything further, keep your distance and warn others without putting yourself at risk. Notify the police immediately: 110 in Germany, 113 in Luxembourg. Describe the already known location from a safe distance and follow the responsible authorities' instructions. Internal project notification is additional and must not delay reporting to the police. Stay away from the object.
Are small, rusty or damaged objects harmless?
Size, corrosion and damage do not establish safety. Ammunition components may also contain dangerous substances or residues. Suspicious objects therefore remain untouched: do not pick them up, clean them, uncover them further or transport them yourself. Repeated small finds may indicate more widely distributed contamination and matter for specialist assessment of the surroundings. Communicate known observations to the responsible authorities; authorised specialists undertake classification. Stay away from the find area for any further enquiries as well.
Must I take a photograph or exact coordinates to report a find?
Do not approach the object again for this purpose. Describe the already known location and your observation from a safe distance; follow police instructions. For later incident documentation, time, already known location, circumstances of discovery, immediate measures taken and authorities informed may be recorded. Stay with observed facts and identify unknown information. For later review, parties involved and decisions made are recorded with their respective basis. Coordinate external communication through a designated responsible contact and agree it with the responsible authorities. Documentation requests must not delay protection or immediate notification.
Who decides on recovery, transport or measures at the find location?
The responsible authorised specialists assess the specific find and agree necessary measures with the responsible hazard response authorities. In Germany, the procedure depends on the respective federal state and case. Safety assessment considers object type, fuze system, condition, explosive quantity, accessibility and location, as well as safe handling. Authorised specialists and responsible authorities decide on recovery, securing, rendering safe or transport. If rendering safe or safe transport cannot responsibly be undertaken, they consider controlled detonation at the find location. Assessment covers the transport chain, including any temporary storage required and relevant dangerous goods provisions. Surroundings and critical infrastructure are considered alongside necessary evacuation, cordon and protective measures against blast and fragments. The responsible authorities define these measures and the organisation required. Client and site management provide known project information and implement the prescribed closure and organisational measures. A photograph or requested date is not a sufficient basis for this safety decision.
Commissioning and cooperation
Clarify scope and responsibilities
What distinguishes a sound quotation from a price per unit area alone?
A sound quotation specifies task, areas, depths, working conditions and expected results. Check which preparation, measurement, interpretation and documentation are included and which prerequisites the client is expected to establish. Access, interference, section changes and additional work steps may affect effort. Prices can be usefully compared only where service scopes are comparable. Also clarify how changed prerequisites and additional services will be handled; responsibility for the cost of official measures is clarified separately under local rules.
What belongs in the service specification?
Describe investigation objective, project location, areas and depths, available documents, constraints, interfaces and expected records. State plan versions, construction phases and handover dates; identify unresolved prerequisites. Where several trades are involved, define who prepares access, communicates changes and receives results. The service must later be verifiable against this scope. Contractual and billing arrangements are agreed for the project and connected with the specialist task described.
How are occupational safety tasks allocated between parties?
In Germany, employers are responsible for their employees' occupational safety, including risk assessment and instruction. Employers check compliance with and effectiveness of defined protective measures and adjust them where necessary. Where several employers are involved, shared hazards and measures are coordinated. The specialist company contributes its commissioned service and associated evidence; site coordination connects the work involved. Record responsibilities, reporting routes and transfer of relevant results in writing. For new construction phases, changed personnel or changed hazards, organisation and instruction are adapted to the actual situation.
What else must be clarified for investigations in the track area?
Hazards from railway operations and necessary protection measures are considered in addition to the specialist investigation scope. Agree track possessions, access, construction phases, parties and necessary result formats with those responsible. An operational track closure and a signalling indication that a track is clear serve different tasks from an explosive ordnance record. For the ground intervention, railway operational organisation and documented investigation status are therefore considered together. Existing infrastructure and interference belong in measurement planning from the outset.
Enter project coordination with a specific question
A planned project question can be addressed when location, proposed intervention and existing documents are available together. Describe the upcoming decision and record needed for it. FONTANA-EOD agrees with you the appropriate specialist task and any further information required.
Terms behind common project questions
Many questions can be asked more precisely when the evidence available, commissioned activity and desired result are distinguished.
Suspicion and suspected area
A suspicion is an initial situation requiring specialist clarification. A suspected area assigns it to a volume. For an enquiry, state the evidence underlying the assessment and the interventions proposed there.
Assess suspicion in relation to the projectSurveying
Surveying is technical investigation with a defined objective. Its assessment depends on method, volume and local conditions. Describe the evidence needed rather than merely naming equipment.
Distinguish survey tasksClearance and recovery
Clearance and recovery are specialist explosive ordnance disposal activities. The specific scope and necessary authorisations are clarified when commissioning. For questions about investigation and construction planning, the existing stage of work is initially decisive.
Distinguish clearance and recovery technicallyClearance statements and documentation
A clearance statement is read according to its described scope. Documentation connects task, result and limitations. For a new construction activity, it is checked whether the existing assessment covers the area and depth.
Read evidence and its limitsEOD and UXO
EOD stands for Explosive Ordnance Disposal. UXO means Unexploded Ordnance: ordnance prepared for use or deployed that did not function as intended. In international documents, these terms are connected with the specific task and local responsibilities. For a commission, the activities, qualifications and records actually required are decisive.
Translate EOD requirements into specialist tasksPublic disposal services and official interfaces
KBD, KMBD or KRD are regional designations for responsible public explosive ordnance authorities. For a query, state the full authority name from existing correspondence, project location and file reference. The responsible authority handles the official case; a private specialist commission governs the commissioned investigation, planning or clearance service. Responsibilities and requirements are clarified for the respective project location.
Assign authority and private tasksBFR KMR and DGUV
BFR KMR stands for Baufachliche Richtlinien Kampfmittelräumung; DGUV stands for Deutsche Gesetzliche Unfallversicherung, the German Social Accident Insurance. BFR KMR apply within their defined scope on federal properties. Their technical approach and contractual application outside this scope are assessed explicitly. DGUV regulations, rules such as DGUV Rule 113-003 and information publications are distinguished according to their respective scopes. The specific relevant requirements and existing provisions are brought together for your project.
Read technical guidance in relation to the taskExcavation supervision
The term describes a specialist task during construction that must be organised with suitable equipment and qualified personnel. The specific service specification connects affected ground volume, construction status, investigation and the record needed.
Describe the service during constructionRelate your initial situation to the next decision
The next specialist step depends on the unresolved decision: obtaining missing evidence, assessing a design change or handing over a completed section. Record the affected area and record needed. Traceable documents enable targeted work before services are scheduled again for matters already resolved.
Planning is beginning and documents have gaps
The first task is to compile existing evidence and the proposed intervention. Missing information remains identifiable. The result specifies the further clarification needed. A particular investigation method is selected only after this specialist assessment.
A new intervention is to use existing results
Before use, location, depth and plan version are compared with the documented investigation volume. Measurement limits, utilities, interfering objects and ground composition may matter for the assessment. The subsequent decision distinguishes records that remain usable from areas needing reconsideration.
A construction section is handed over to subsequent trades
The stage actually reached is connected with the results plan and report. Unresolved areas and limitations remain visible. Handover should enable site management to relate the next decision to the relevant ground volume without extending assessments to neighbouring areas.
Make a general answer useful for your project
A specific project question includes the affected ground volume, proposed intervention and existing evidence. Mark the point concerned on the plan and identify the unclear statement. This makes it possible to assess whether an explanation of existing documents is sufficient or an additional specialist service is needed.
Tailor the question to a specific intervention
Rather than only asking for clearance, describe the proposed construction activity and volume needed. A shallow utility crossing, deep foundations and later land use may place different requirements on the record. The actual task is decisive.
Find measurement limits in the report
If an answer refers to local conditions, examine the relevant information in your report. An area affected by substantial infrastructure or an inaccessible edge may limit the assessment. Identify the affected zone and ask what it means technically for the proposed intervention.
Describe the design change and new decision needed together
A relocated point or deeper excavation is compared with the previous plan version. Record the change on the site plan and in the task description. This allows assessment of which part of the existing record still fits and where additional work is needed.
Which specialist service addresses the unresolved project question
Historical clarification, investigation of individual deep interventions and work during construction serve different tasks. Select the specialist service according to the unresolved question, affected area and depth and proposed construction stage. The scope needed is described specifically from this.
Historical evidence is missing or unclear
If the basis for suspicion is not yet understandable, existing sources and the volume considered are brought together. Historical aerial photograph assessment may contribute specialist information for this. Identify available documents and the assessment needed for your planning.
Individual deep interventions are being prepared
For drilling, foundations or comparable points, specify location, depth and construction method. Investigation is aligned with this volume. Existing area-specific results are considered alongside it but are not transferred to the deep intervention merely because they are nearby.
Investigation must fit construction progress
Describe areas that become accessible only after demolition or at a defined construction stage. The specialist task during construction is aligned technically and organisationally with this. The work status needed before the next intervention and its documentation are specified.
Ask project questions based on actual working conditions
Ongoing uses, phased work and demolition change the working volumes available. Investigation planning needs access, existing infrastructure, construction stages and handover points. A sector name alone does not describe these conditions; the actual work at the respective location is decisive.
Construction beside facilities in use
Identify ongoing uses, possible access and available working areas. Operator requirements are connected with the planned intervention. For closures, site management and operator agree access arrangements, spatial separation and other work with the relevant requirements. Continued operation outside an affected area requires genuinely effective and monitored separation and the necessary decisions. The specialist service is incorporated into these agreed working conditions.
Describe operating conditions for the investigationConstruction in sections
Describe which areas will be treated in sequence and which results should be available at each handover. A question about sequence thus becomes specific coordination of investigation, records and construction stages.
Specify questions about construction sections and handoversDemolition and changed working volumes
Demolition may change access or make areas accessible that could not previously be measured. State the construction stage proposed for the planned investigation. The specialist task relates to this stage and is checked again if further changes occur.
Understand investigation needs by construction stageFrom the first question to the next steps
A query may be resolved during document comparison. If additional investigations are needed, requirements, execution and result handover are coordinated with construction planning. Identify when the next decision is needed and who must make it. For an immediate find, prompt reporting to the police takes priority; further project organisation follows the responsible authorities' instructions.
Identify the project question at initial contact
Describe the project location, proposed work and outstanding decision. State which documents exist and when the next step is planned.
Read existing documents together
Reports, plans and official information are assigned to the current intervention. Missing appendices and unclear spatial references are recorded so that further work begins on a traceable basis.
Add historical information where needed
Unresolved historical questions are addressed according to the assessment objective needed. Suitable research and aerial photograph assessment may support specialist planning; the result remains identifiable with its limits.
Agree methods and working conditions
Investigation objective, area and depth are connected with ground conditions, existing structures and accessibility. This determines a suitable specialist task for surveying or work during construction.
Prepare execution and interfaces
Working areas, access, construction status and necessary preliminary services are agreed with the parties. Defined reporting routes connect the specialist company with site management and operator. Where several trades are involved, shared hazards and spatial interfaces are considered; changes are clarified before the work affected. Project management tracks effects on dates and commissioned services.
Perform the investigation within the agreed volume
Where investigation is needed, the commissioned service is performed with the agreed equipment within the agreed volume. Measurement data, findings, working conditions and limitations are recorded with location and depth references. Inaccessible areas remain traceably identified. Changes from the proposed task are communicated and further action agreed.
Interpret results and record the stage reached
Specialist interpretation assigns measurement data and findings to the relevant area or point. Report and results plan describe the assessment, technical limits and outstanding clarification needs. The stage actually reached thus becomes traceable for subsequent handover and the construction decision.
Hand over records for the next step
Report and plans show the stage reached. The construction decision relates to its scope. For a later design change, the fit of the existing assessment is checked again.
Clarify unresolved investigation, record and site questions
Further work is aligned with the outstanding task: determining a suitable investigation, using existing results, clarifying regional requirements or agreeing a specific specialist service. Identify the affected volume and decision for which a basis is needed.
Which investigation fits?
Define the outstanding task: assess historical indications, investigate the ground technically, supervise work as specialists or interpret results. Describe the intervention and investigation objective. An appropriate enquiry scope also identifies expected plans, reports and handovers and execution prerequisites.
Compare specialist services by taskHow is a result used?
Compile the report, appendices and current plan. Identify the decision to be made on this basis. The record and assessment limits are thus considered together.
Use existing results traceablyWhich regional interface is relevant?
Project location and existing correspondence provide the starting point. State the responsible authority, date, file reference and specific unresolved requirement. For specialist coordination, this information is connected with the property, intervention plan and previous work status. Regional clarification thus remains related to your case.
Identify the region and previous coordinationWhat is needed for initial specialist coordination?
FONTANA-EOD agrees with you which specialist task follows from the outstanding question. Submit location, intervention and available documents. Identify when the result is needed and its recipients so that service scope and handover can be aligned with your project.
Submit the project question with documentsConnect the answer with traceable documents
For reliable reuse, the initial situation, work and conclusion belong together. A single sentence from a report is often insufficient.
Initial data and site plan
Historical documents, available official information and earlier investigations are assigned to the plot, construction site or route section. The current plan describes the proposed intervention. Source gaps and different plan versions remain identifiable.
Measurement data, findings and assessment
Survey results are connected with the volume actually investigated and investigation conditions. Specialist interpretation explains the significance of findings and justifies any further clarification needed. Technical limitations, unresolved areas and different construction stages remain identifiable in the record. For construction supervision, plans and report are handed over together so that results can be located unambiguously and assigned to the next work step.
Report and completed work
The results plan, report and clearance record where applicable record the stage reached. The project file and site management can identify which task is complete and which questions remain. An assessment remains bound to the documented scope. Where clearance work has actually been performed, the clearance record documents the areas and depths treated, clearance scope performed and result.
Clarify the scope of existing records
Do you want to clarify whether existing results fit the next construction section? Compile the report, plans and proposed intervention. Identify the assessment needed and unclear areas or depths. The enquiry thus connects the record status and its assessment limits with a specific project decision.
Discuss records and the proposed interventionWhat informs specialist assessment
Qualifications, occupational safety organisation and documentation depend on the actual activity. For a project in Germany, prerequisites under explosives legislation, employer tasks and relevant technical rules are connected with the specific commission. Official requirements and responsibilities at the project location are considered; requirements applicable to projects in Luxembourg are clarified separately.
Explosives legislation and commissioned activity
The German Explosives Act distinguishes company permits, responsible persons and personal certificates of competency. The First Ordinance on the Explosives Act contains supplementary requirements, including specialist knowledge and state-recognised courses. Identify proposed activities precisely enough for the necessary prerequisites to match. An investigation, recovery and subsequent handling of found ordnance are assessed according to their actual scope and the responsible procedures.
Risk assessment and relevant technical rules
In Germany, risk assessment and instruction are employer tasks under the Occupational Safety and Health Act. The Construction Sites Ordinance concerns the relevant coordination, while the Industrial Safety and Health Ordinance concerns safe use of work equipment; DGUV Regulation 1 contains basic prevention duties. The DGUV Information 201-027 supports risk assessment and protective measures during explosive ordnance clearance. The DGUV Rule 113-003 concerns dismantling objects containing explosives and destroying explosives or corresponding objects, including disposal of found ordnance. Application considers the activity and scope of the respective document.
Specialist approach and official procedures
The BFR KMR structure investigation, planning, execution and documentation within their scope on federal properties. Project location and case determine official find and hazard response procedures and interfaces with responsible explosive ordnance authorities. For planned specialist services, authority conditions and existing documents are included in defining the commission. Record which requirements are binding provisions or contractual agreements and which authority needs each record.
Which information makes a specialist answer reliable
A traceable project context facilitates coordination and later use of the result.
Specific question
Identify the decision needed and unclear statement. For an existing report, the exact page, location on the plan and a short question help. Specialist clarification needs can then be addressed specifically.
Defined volume
The area, route or point can be assigned on the current site plan. Distinguish the historically suspected area, volume actually investigated and ground volume needed for the next construction activity. Differences are marked visibly.
Described intervention
Construction method, depth and associated reference level are stated insofar as defined. Where intervention depths vary, areas are shown separately. Piling, drilling or anchoring work is also described with the volume actually affected. Proposed compaction work and expected vibrations are communicated as working conditions.
Complete context
The report, plan appendices and supplementary correspondence are provided together. An appendix list helps identify missing components. Statements from individual sections are read with their associated prerequisites, results and limitations.
Identifiable limits
Unclear information, unresolved areas and restricted measurement conditions are identified. Record which conclusion for the proposed intervention still needs clarification. The status needed thus remains distinguishable from tasks already completed.
Current status
Design changes, intervening earthworks and new evidence remain traceable with dates and plan versions. The next decision uses genuinely current documents. Older records retain their documented scope and are compared with the new task.
Provide the project location and previous coordination
Project location, property and existing case determine regional coordination. Compile previous correspondence in full and mark the current intervention. The responsible authorities and requirements for this project are decisive.
Region, property and case
State the municipality, address and, where applicable, plot reference. Include existing correspondence in full with dates and appendices. FONTANA-EOD's regional focus areas include Lower Saxony, Bremen, North Rhine-Westphalia, Hesse, Rhineland-Palatinate, Bavaria, Baden-Württemberg and Saarland. For your project, location, specialist task and existing case are considered together. Further clarification can thus build on previous coordination.
Understand the project location and regional documents
Specialist task at your construction site
Mark the proposed working areas and describe the decision needed. Identify missing information openly and state known access or use restrictions. For a specialist enquiry, the existing status and specific unresolved question are sufficient to determine further clarification needs.
Ask the project question with a location referenceFrom background information to usable results
Documents accompany different work stages. Their function is connected with the respective project question.
Historical evidence as the starting point
A historical assessment places available sources and the volume considered in context. Later filling, soil replacement and alterations may have changed the present situation. Connect historical indications with known terrain changes and the current construction design. For queries, source, spatial reference and derived assessment are read together. On this basis, a historical record is assigned by specialists to the present ground volume.
Explore questions about historical information
Describe the appropriate investigation
A specialist service is selected according to the result needed and working conditions. Identify the information sought, available access and proposed construction stage. For existing utilities, installations or areas substantially affected by infrastructure, possible limitations are considered when defining the task. The enquiry scope describes the investigation actually needed.
Distinguish investigation tasks precisely
Document results for site management
Report and plan record the stage reached. At handover, assign the service performed and its assessment scope to each area or point. Unresolved areas and limitations remain identifiable for site management. The next work step is coordinated with this record and other decisions needed.
Understand records and handovers
Assign background information, records and project enquiry
Unclear terms are clarified through their technical context and existing results compared with the proposed intervention. For a project enquiry, unresolved issues are compiled with the plan and document status. Select further work according to this task.
Understand the background
Assign unfamiliar terms to the document and activity actually performed. For a query, record the exact wording and associated plan area. Specialists can then clarify the relationship between the evidence available, investigation and assessment you need.
Explore explosive ordnance assessment knowledgeBring documents and records together
Connect the commission, investigation performed and result record with the proposed intervention. Check which areas and depths were covered, which assessment limits apply and to whom the record is to be handed over. Responsibilities and further requirements are coordinated with this specific project decision.
Read documentation in the project contextDiscuss your project
Submit the existing status and outstanding decision. State the location and proposed intervention. Specialist coordination can then be aligned with your actual project.
Ask a specific project questionPrepare the next enquiry with the appropriate information
The information must make the proposed intervention understandable. Missing documents are identified and supplemented specifically as work progresses.
Location and construction activity
Provide the address or region, plot reference and a current site plan. Mark the construction site, route, borehole points and additional working areas. Describe intervention depth and construction method insofar as defined.
Existing information
Include earlier documents, aerial photograph assessments, survey reports, utility plans and known authority conditions. Identify missing appendices or the older plan version a report concerns. Complete documents facilitate specialist assessment.
Project status and desired decision
Identify construction dates, the next work step and assessment needed. Is the enquiry about tendering, investigation planning, report interpretation or handover? Also communicate changes since the last work.
Have your project assessed
Whether historical aerial photograph analysis, explosive ordnance surveying, surface surveying using GPR, magnetometry or TDEM, deep-ground surveys, downhole surveys, excavation supervision, area clearance or ordnance recovery is needed depends on the location, ground disturbance, depth, ground and existing documents. An early ordnance assessment provides clarity for tendering, programming, occupational safety and construction.
FONTANA-EOD combines its Section 7 SprengG licence, specialists holding Section 20 SprengG certificates of competence, suitable survey and clearance methods, and traceable documentation. Send the site plan, depth of ground disturbance, construction phase and existing documents for an initial technical assessment.
