Explosive ordnance surveys in Celle
If ground investigation boreholes, archaeological work and an explosive ordnance assessment are planned for your construction project in Celle, these activities must be coordinated. FONTANA-EOD undertakes the commissioned explosive ordnance investigation and documentation. We establish with you which areas are to be investigated and which results are needed before the next ground works.
Distinguish explosive ordnance, ground investigation and excavation reports.
Coordinate the work areas and sequence of investigations.
Hand over the required reports to site management.
Assess the construction project
Coordinate ground investigation, archaeology and explosive ordnance assessment
Planned drilling, excavations and preparatory ground works each require clearly established prerequisites. For your project in Celle, we coordinate the explosive ordnance investigation with the planned ground works and handovers of results. The reports from the individual disciplines remain distinguishable by their respective tasks and findings.
Project site
Connect the site with the specific construction task
Site and existing requirements
Specify the actual project location with a site plan and the affected land parcels. Existing information, conditions and reports are assigned to this area. Celle is in the district of Celle in Lower Saxony; the district belongs to the Lüneburg administrative area. The municipal contact for explosive ordnance matters is determined by the actual project address. For projects outside the city, the municipality responsible locally must be involved. Identify the version of the records and the body responsible for the project location for each site plan.
Local context
Assess ground conditions, archaeology and explosive ordnance separately
Local starting point
On its project page for the central section of the B3 Celle bypass, the Lower Saxony State Authority for Road Construction and Transport addresses explosive ordnance and archaeological work in separate sections. The information relates to this road project by the state authority. It does not establish the contamination status of other sites in Celle.
An air raid struck the railway facilities in Celle on 8 April 1945. The garrison history published by the city’s Garrison Museum describes this raid and the city’s earlier military use. For a present-day construction site, historical maps, aerial photographs and records are related to the land parcels actually affected. Earlier land-use boundaries, reconstruction and later changes to the ground form part of this comparison where the available records provide information about them.
Implications for construction planning
For your own planning, what matters is the question an investigation is intended to answer. A ground investigation report does not replace an explosive ordnance investigation. Archaeological and environmental questions must also be addressed by the specialists responsible for them. Where several disciplines are involved, their work areas, prerequisites and handovers of results should be coordinated before the first ground works.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For the commissioned activities, the applicable technical requirements and questions of permits, competence and responsibility are clarified. The services actually planned are decisive. Required permits and certificates of competence are assigned to the activities described and the responsible persons.
Link occupational safety to the construction sequence
The risk assessment, work areas and communication arrangements must suit the planned activities. Specialist explosive ordnance work is coordinated with the other construction activities. Site organisation, traffic safety and other technical assessments retain their own responsible parties. Joint coordination assigns the relevant specialist work and responsibilities to the affected construction sections.
Use technical findings correctly
A measurement anomaly first requires specialist assessment; its appearance alone does not identify it as explosive ordnance. If an object is genuinely suspected to be ordnance, the prescribed reporting procedures and the measures set by the responsible authorities apply. Investigation reports specify the work completed and its limitations, so that results are not extended to unexamined areas or later design changes.
The preparatory work for the central section of the B3 Celle bypass brings together several separate specialist tasks within a road construction project. For local information and reporting explosive ordnance finds, the City of Celle identifies the municipal bodies and police. The LGLN describes wartime aerial photograph analysis for hazard investigation and explains who performs which explosive ordnance assessment tasks. For your own project, the affected area and the technical findings needed are defined.
The principles of clearance planning relate the investigation objective to the construction task. The specialist geophysical principles help assess methods and local survey conditions; the BFR KMR documentation requirements relate results to investigated areas and depths. The DGUV FAQs on explosive ordnance clearance address, among other matters, the technical requirements for preventive explosive ordnance clearance during construction.
The defined remit of the BFR KMR guidelines concerns federal projects. Their technical principles are compared with the locally applicable requirements and responsibilities for the project.
For work in Germany, the permit, certificate of competence and responsibilities for the specific activity are assessed under the Explosives Act and the First Ordinance to the Explosives Act. The risk assessment under Section 5 of the Occupational Safety and Health Act relates to the planned activities. The DGUV Information 201-027 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.
Section 7 of the Explosives Act concerns the commercial permit for activities requiring a permit, while Section 20 concerns the certificate of competence held by responsible persons. Under Section 1b, the Act also covers searching for found munitions. The commission describes the activities to be carried out and the responsible persons assigned to them.
Working together
Distinguish the tasks of client, designers and specialist contractor
Client and operator
The client describes the project and provides the available project records. The operator adds requirements for use, access and timing. A coordinating contact brings the parties together; individual tasks remain assigned to the named parties. Before commissioning, it is clearly recorded what information is missing, who will obtain it and what decision the result is intended to prepare.
Planning and construction management
The specialist designers describe areas, depths, construction methods and changes. Site management coordinates the planned sequence with the construction contractors and agreed specialist works. Results are assigned to the respective intervention. A technical plan change is communicated early enough for its effect on the survey task to be assessed before construction. Organisational construction stage boundaries remain distinguishable from technical survey boundaries.
Specialist company and competent bodies
The private explosive ordnance specialist contractor performs the agreed investigation and documentation work. Official requirements and decisions are clarified with the respective responsible bodies. The records needed for a specific procedure depend on the location and project. The technical report documents the specialist work carried out and its area, depth and limits of conclusions. The responsible bodies make official decisions concerning subsequent groundworks.
The City of Celle’s General Public Order department is the municipal contact for explosive ordnance finds. In Lower Saxony, the state explosive ordnance disposal service supports municipalities within its remit. For the project, official requirements, reporting channels and necessary coordination are related to the planned investigations. Ground investigation planners and archaeologists address their respective technical questions; the explosive ordnance specialist documents the commissioned investigations and their limits.
Investigation task
Which specialist task comes next?
Assess the explosive ordnance question separately
Existing official correspondence, aerial photograph analyses and technical explosive ordnance reports are related to the planned ground works. Information from other disciplines can provide important constraints. Their investigation results, however, each answer the question commissioned. The first step is therefore to establish which explosive ordnance findings are available and what still needs to be established before the planned ground works.
Assess historical documentsCoordinate the method with the other work
A suitable investigation is based on the objective, depth and conditions of the work area. Planned boreholes or excavations are considered at their actual locations. Those involved clarify the necessary access and preparatory work. The agreed scope should be described so that subsequent specialist planners can understand the ground works for which the result may be used.
Compare investigation methodsProject types
Coordinate several specialist tasks before ground works
Ground investigations for foundation design
The proposed investigation locations are described by location, depth and method. Creating them already involves ground works and is included in explosive ordnance planning. The ground investigation planners then need their own results for the foundation design. A coordinated sequence connects both tasks without treating the geotechnical report as a substitute for an explosive ordnance report.
List the investigation points together with unique identifiers, locations, maximum depths and level references. Add equipment positions and preparatory ground works wherever these disturb the ground. If an obstacle requires a point to be relocated, the explosive ordnance planners receive its changed location before work begins. The geotechnical investigation needs and the location assessed for explosive ordnance remain traceable together.
Understand downhole surveys
Archaeological work areas before construction
Where excavations are planned, their areas and work steps are compared with the explosive ordnance prerequisites. Access and working routes may also matter for preparation. The archaeological plan describes its task, while the explosive ordnance investigation documents its own scope and limitations. Whether work can take place at the same time or alongside other work is clarified from the specific conditions.
Provide the proposed trial trenches, excavation boundaries and working depths together with the planned access routes. The work sequence depends on which areas are needed first and where tasks overlap spatially. If archaeological work results in different ground works boundaries, these are checked with the explosive ordnance planners before further ground works. Archaeological finds and explosive ordnance investigation results each remain assigned to their own specialist task.
Specialist services and investigation tasks
Preparatory work by several contractors
One contractor builds the access road, another carries out ground investigations, and civil engineering work begins later. At these transitions, it must be known what needs to be established before each ground intervention. The shared programme alone does not answer this question. Site management assigns complete reports and agreed prerequisites to the work steps and passes changes to the affected specialist planners.
For each handover, agree a responsible recipient and the documents required. The civil engineering contractor, for example, receives the reports relevant to its excavation, while the drilling contractor needs the assessed borehole positions and depths. After preparatory work, the areas and depths changed by it are compared with the existing investigation status. A changed sequence is communicated to the affected parties before they base their work on it.
Coordinate the sequence and 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.
Before a site purchase, existing ground investigation, environmental and archaeological reports are organised by their respective tasks. Request the explosive ordnance records separately, with complete maps. Planning depends on which present-day investigation points or construction areas are covered by the investigation scope at the time. Missing results or appendices are identified before further investigations and the access they need are commissioned.
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.
If ground investigation boreholes or archaeological preparatory work are tendered before the main structure, their explosive ordnance prerequisites already belong in that tender. Describe the borehole positions or excavation areas with depths and sequence. Those involved must be able to identify who provides the work areas, which investigation takes place first and which report is required before the next ground intervention. Additional or relocated points are submitted for assessment with the current plan version.
Clarify preparatory work in the programmeAgree a clear scope and schedule
A reliable process distinguishes work already technically clarified from prerequisites still unresolved. If an area will only be partly accessible, this must be taken into account when commissioning the work. Handover and assessment of results also need time in the construction programme. Specific coordination connects the described scope with access, records, execution conditions and the date by which a decision is needed.
For comparable quotations, specialist contractors receive the same plan versions, investigation objectives and existing reports. Specify the documentation scope and handovers to ground investigation planners, archaeologists and site management. Official conditions are provided in full, with their associated appendices. This allows the offered investigation scope to be compared with the ground works actually planned.
Discuss the scope and scheduleTasks at the site
These activities must be coordinated
01
Drilling and ground investigations
Planned ground investigations are themselves interventions in the ground. Their locations and depths therefore belong in the assessment of suspected explosive ordnance contamination. Clarify the explosive ordnance prerequisites before drilling or carrying out ground investigations.
02
Archaeological work areas
Where archaeological ground works are planned, the work areas and sequence must be coordinated with those involved. The archaeological task and explosive ordnance investigation status remain documented separately. An archaeological excavation alone does not establish that the area has been investigated for explosive ordnance.
03
Access routes and working areas
Preparatory measures can also disturb the ground. If access roads are to be built, surfaces stripped or facilities provided with foundations, include these ground works in the plans. Take account of them when preparing the explosive ordnance assessment.
04
Handover to the next contractor
At the transition between investigation, preparatory work and construction itself, it must be known which results apply and what remains unresolved. Reports with their associated plans and limitations must be available before the subsequent work.
Project documents
Documents that establish the next step
File technical reports by their task
Ground investigation, environmental, archaeological and explosive ordnance reports answer different questions. A shared project file identifies titles, authors, plan versions and scope. Complete appendices belong with them. After clearance work, the explosive ordnance records include the clearance record with the actual scope and results; the areas covered remain linked to their associated site plans. Anyone using a document for a subsequent work step must be able to identify what it actually establishes and which further specialist assessment is still needed.
Record prerequisites for the handover of results
Identify which contractor needs which documents before its own ground works. Assign a responsible contact to assessments still outstanding. Verbal feedback or an isolated map extract does not replace the agreed report handover. For changed investigation points or additional depths, the affected investigation scope is compared again before work begins.
Construction sequence
Coordinate investigation and construction sections
Before the first ground investigation
Coordination begins with the earliest planned ground intervention. A ground investigation borehole or archaeological trial trench may precede the main civil engineering work and therefore requires its prerequisites to be clarified beforehand. Those involved compile the planned work with locations and depths. The necessary records, technical decisions and handovers of results are then arranged so that the next activity can begin on a traceable basis.
At the transition from investigation to construction
After preparatory investigations, the construction sequence actually planned is compared with the results again. Changed foundations or additional services may affect areas different from the original investigation. Site management needs the current version of all relevant technical reports. It remains identifiable which specialist provided each finding and which points still need clarification before the following ground works.
Method selection
Select methods according to the task and survey conditions
Historical records and aerial photographs
Historical aerial photograph assessment and other old records help place the basis for suspicion in its spatial context. The available images, their evidential value and the limits of the area considered matter. The absence of an identifiable indication must be distinguished from a technically surveyed ground area. The assessment is considered together with the planned intervention and other available findings. It can support the choice of a survey, but is not a measurement of the present-day subsurface or confirmation for all future works.
Understand aerial photograph assessmentMagnetometric survey
Magnetometric methods detect magnetic anomalies. Whether they can address the specific survey task depends, among other things, on the expected objects, ground conditions, interference and required survey area. Fences, utilities or existing structures may affect interpretation. A measurement signal is therefore not described as ordnance solely because of its strength. Method, interpretation and any further investigation are planned as a connected specialist task.
Understand the scope of magnetometryElectromagnetic methods
Electromagnetic investigations can be suitable for particular metallic targets and site conditions. Their suitability must be explained for the task, rather than inferred simply from the availability of equipment. Interfering installations, accessible areas and the findings required must also be considered. Results are documented with their location and survey conditions. The specialist assessment determines whether a supplementary method is needed; this remains a project-specific decision.
Understand electromagnetic surveyingGround-penetrating radar
Under suitable conditions, ground-penetrating radar can provide information about subsurface structures and reflections. Ground conditions, moisture, installations and the particular survey task affect interpretability. An anomaly is not automatically ordnance, and an area with no apparent anomalies is not general evidence for arbitrary depths. The specialist interpretation and its limits are documented with the instruction. A survey for another purpose is not adopted without checking as ordnance evidence.
GPR and limitationsDeep-ground and downhole surveys
For deeper groundworks, it may be necessary to establish whether a surface investigation can provide the required findings or another approach is needed. Preparation includes the location, depth, borehole layout and existing services. Creating access for the investigation must also be properly planned by specialists. A general depth figure or standard grid cannot replace that work. Findings remain limited to the areas actually investigated and the method used.
Prepare deep interventionsSurvey during construction
If a necessary preliminary investigation cannot be completed, it is assessed whether a technically planned approach during construction is suitable. This includes coordinated investigation, interpretation and communication of findings within the planned workflow. A necessary survey remains part of the agreed approach; visual checks supplement it. Site management needs a clear description of when specialist work takes place, how new findings are handled and which areas remain unresolved.
Agree the approach during constructionTechnical assessment
What to clarify before the investigation
Check existing explosive ordnance records
Existing explosive ordnance records and any necessary aerial-photo analysis provide a basis for further planning. For an application to the LGLN, the area concerned must be clearly marked. Results from another project or the city’s general history do not replace the comparison for your own ground works.
To compare several specialist investigations, the original investigation areas, plan versions and types of results are recorded alongside one another. An aerial photograph analysis, survey report and clearance record describe different specialist activities. Each document must include its spatial reference, the task addressed and complete appendices. Site management can then identify which information may be used before a specific ground investigation and which investigation still needs preparation.
Investigation objective and survey conditions
A geophysical survey is described by its investigation objective, local conditions and limitations. Ground investigation data can contain important constraints but do not replace this investigation. Necessary preparatory work and questions are clarified between the responsible specialist planners before work begins.
Ground structure, fill, utilities, reinforcement and other sources of interference are considered when selecting the method. For a deeper ground investigation, it must be clarified whether the required findings can be obtained from the surface or a suitable deep-ground or borehole survey needs preparation. The investigation location is checked against the geotechnical borehole list. The prerequisites for creating the necessary investigation access and for the later ground investigation borehole are each clarified.
When supervision during construction is necessary
According to the DGUV, visual observation during excavation alone does not meet the state of the art for preventive explosive ordnance clearance. Professionally planned explosive ordnance clearance during construction must be distinguished from this. Explosive ordnance specialists must decide whether it is necessary and what its scope must be. The presence of another expert does not replace this assessment.
With a suitable approach during construction, each working layer is technically investigated and assessed before the agreed removal in layers continues. Visual checks supplement this investigation. The specialist plan describes the proposed scope to the agreed excavation base and, where relevant, along walls or slopes. Stop signals, authority to issue instructions and communication with the other contractors are agreed before work begins. The responsible bodies are involved if a suspicious object is encountered.
Next steps
Prepare investigations and handovers of results
Compile the initial ground works and records
For each discipline, describe the reason, investigation question and proposed ground works. The overview should also list existing results. Check which questions have already been answered by an investigation result and which remain to be addressed. For the initial contact, compile the current site plan, proposed work areas, borehole locations and depths. Existing explosive ordnance reports, aerial photograph analyses and official correspondence are compared with the present ground works. Spatial references, plan versions and complete appendices show which findings can already be used and which information is still missing.
Assess historical questions and aerial photographs
Where the evidence for the area concerned is unresolved, the necessary historical research and wartime aerial photograph analysis are carried out. Available photographs, land-use records and earlier changes to the ground are related to the specific area. The analysis records its findings and limitations and provides a basis for subsequent investigation planning.
Define methods and requirements
Assign the required records, coordination and access to each planned work step. Record which prerequisites are still missing. A shared construction programme can support coordination but does not replace a technical decision. The explosive ordnance planners select the method according to the investigation objective, required depths, ground and existing interference. Depending on the task, suitable surface methods, a deep-ground survey or technically planned supervision may be considered. The selection and necessary preparatory work are coordinated with ground investigation planners, archaeologists and site management.
Investigate and assess findings
The commissioned survey or technically planned supervision is carried out in the described area. Survey data and anomalies are assessed by specialists with regard to the method and local conditions. Inaccessible areas and further clarification remain spatially identifiable. If a suspicious object is encountered, work stops and the responsible bodies are notified.
Hand over results with their associated plans
Specify who needs which result for the next step and how it will be handed over. Associated plans, limitations and outstanding assessments belong with it. Hand over complete reports with their plans and limitations. The report, associated plans and, where applicable, clearance record document the actual specialist work with areas, depths and limitations. Ground investigation, archaeological and explosive ordnance findings remain assigned to their respective authors and tasks.
Compare the next ground works with the results
If investigation points move or deeper ground works are added, it must be assessed which specialist tasks are affected. The change is recorded in the respective documents. Approval of a construction change does not automatically extend the scope of an existing explosive ordnance report. Before the following ground works, it is checked whether the documented result covers the area, depth and working method. Outstanding specialist work and necessary coordination with the authorities are assigned a specific next step. Site management passes the relevant plan version and complete records to the next contractor.
Documentation
Hand over complete reports separated by discipline
Findings and their scope
The explosive ordnance results include the area covered, method, investigation scope and any limitations. The shared project file should clearly distinguish these records from ground investigation, environmental and archaeological reports. A shared overview must show which questions the individual reports answer and which areas remain unresolved.
Project responsibilities
According to Lower Saxony’s description of responsibilities, municipalities take official measures; the KBD undertakes the explosive ordnance disposal tasks identified there. Commercial specialist contractors carry out the agreed investigation and documentation work. For specific decisions, those involved must therefore be able to identify whether a document contains a technical investigation, a planning recommendation or an official requirement.
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 findings are identified. They are shown separately in the report and overview plan. Planners and site management can then decide specifically which areas still need work and when a suitable investigation will become possible.
Clarify changes before intervening in the ground
A new location, additional depth or different construction methods are compared with the existing results. The current ground works and plan version remain decisive even if the project name is unchanged. Feedback is provided before the affected work so that an unresolved question can be incorporated into the workflow.
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 results together with their scope
A statement is understandable only with its investigation task. Check the area and depth described, methods used and restrictions. A report title or single result line is insufficient. For new work, these details are compared with the current plan to establish which knowledge remains usable and which question is unresolved.
Understand investigation reports and their limitationsUse project terminology unambiguously
Document review, surveying, construction-phase specialist work and recovery are different tasks. An enquiry need not identify the correct method in advance. An accurate description of the intervention and required decision is more useful. This establishes the appropriate technical scope and prevents a general term from meaning different things in design, procurement and execution.
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 assessmentSpecialist 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.
Assess investigation reports

Determine the specialist service from the planned groundworks
Historical assessment, technical investigation and further work answer different questions. For your enquiry, specify whether existing records are to be assessed, an area technically investigated or assessed findings addressed further.
Compare servicesCoordinate the project sequence with everyone involved
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 several investigations on a construction site in Celle
Does a ground investigation report replace an explosive ordnance investigation?
No. The investigations serve different purposes. A ground investigation report can provide relevant information about the ground. Whether and to what extent an explosive ordnance investigation is necessary is clarified with the responsible bodies on the basis of the suspected contamination and planned ground works.
Can archaeological work and explosive ordnance work take place at the same time?
Work areas, ground disturbance and risks posed by one activity to another must first be coordinated by the specialists. Necessary protective measures and responsibilities must be defined before the teams work in parallel.
What does the B3 project establish about my site?
The state authority’s information applies to the road project described there. For your site, its own records and the planned ground works are assessed. The B3 findings cannot be applied to other areas.
Who brings the different results together?
The project organisation should identify who brings together plan versions, technical reports and outstanding points and passes them to those involved. Technical responsibility for individual findings remains with the respective author or responsible body. Even a shared plan must show who provided each technical finding.
Where do I report possible explosive ordnance in Celle?
If possible explosive ordnance is found, stop work at the location immediately. Do not touch, move or expose the object further. Leave the immediate area, keep your distance and keep others away without putting yourself at risk. In Germany, notify the police immediately on 110 and follow their instructions. Inform site management and the client; internal reporting must not delay the emergency call. An enquiry form for planned construction projects is not an emergency reporting channel.
Does an investigated borehole location also cover an alternative location?
Only if the documented scope actually includes the alternative location and planned depth. A relocated point is checked with the specialist planners before work begins. Mark possible alternative positions in the enquiry rather than assuming on site that they have been investigated.
What affects the work involved when several disciplines are participating?
Alongside the area, depth and investigation objective, the necessary handovers, access and timing dependencies matter. State which specialist activities take place first and which reports they require. Missing records and changed work steps may require further coordination or an extension of the investigation scope.
Can a shared site plan replace the individual reports?
A shared plan makes spatial coordination easier. It must, however, identify the reports and plan versions on which the recorded findings are based. Technical results, methods and limitations remain documented in the respective complete records and are passed on with their appendices.
Project enquiry
Enquire about explosive ordnance assessment for your project in Celle
Show the planned specialist investigations
Send the site plan with planned boreholes, excavations and preparatory ground works. Specify the depth, method and proposed sequence for each. Add existing explosive ordnance records and technical reports that may be relevant to the investigation conditions.
Identify contacts and handovers of results
Tell us which specialist planners and contractors are involved and who coordinates the shared plan version. Coordination depends on which result is needed before which work step. Outstanding points and anticipated plan changes should already be identifiable in the enquiry.
Add the current project status, planned construction dates, official conditions with their appendices and existing utility information. Mark possible alternative borehole locations, additional working areas and the respective level reference. For each investigation, identify the complete result required before the next ground works.

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.
