Explosive ordnance surveys in Saarland for your construction project
For project owners, design offices and construction companies in Saarland, existing suspicion of explosive ordnance is related to the works actually planned in the ground. FONTANA-EOD in Gersheim carries out the agreed preliminary investigations, surveys and specialist support during the works. Send a site plan, intervention depths and existing reports. These are used to coordinate further information needs, suitable investigations and handovers to designers and site management; where items are found, the reporting procedures to the responsible public authorities apply.

How does an explosive ordnance assessment for a project in Saarland begin?
Before excavation, drilling or utility construction, existing suspicion of ordnance is compared with the location and depth of the planned ground interventions. Existing historical assessments and technical reports are reviewed with their appendices, and outstanding tasks are identified. FONTANA-EOD in Gersheim carries out the commissioned research, investigation and documentation for the specified area. If ammunition is found, the responsible police authorities and the state ordnance disposal service are involved.

Base enquiries from Saarland on the specific work site
FONTANA-EOD in Gersheim develops the planning from the actual area, available findings and planned ground interventions. For municipal, commercial and private projects, the respective responsibilities remain applicable. Identify the authorities and other parties involved and the records available. The specialist contractor’s tasks and state hazard response are clearly distinguished for the particular circumstances.
Saarland is in Germany. Specify the municipality and project address, together with the Regionalverband or district, so that the parties involved can be correctly identified. For routes crossing into Rhineland-Palatinate or France, requirements are clarified separately for each section. The company headquarters in Gersheim is the contact for specialist services; the authorities’ responsibility depends on the actual project location and circumstances.
Information on explosive ordnance surveys in Saarbrücken, Neunkirchen (Saar), Homburg (Saar), Saarlouis, St. Ingbert, Merzig, Völklingen and St. Wendel helps you prepare your project enquiry. The records and planned ground interventions on the particular property remain decisive.
Local context
Your contact in Gersheim
FONTANA-EOD in Gersheim
FONTANA-EOD Consulting & Engineering GmbH is based in 66453 Gersheim. From here, we coordinate enquiries from Saarland, ranging from individual properties and municipal civil engineering works to industrial, railway and utility projects. The initial assessment considers the project’s location, available historical findings and planned ground intervention.
The Saarbrücken City Archive describes severe attacks on Malstatt, Burbach and Alt-Saarbrücken on 5 October 1944. It also documents attacks on infrastructure and residential streets, as well as subsequent artillery fire. Such documented local circumstances help place an affected area in its historical context. They are compared with the actual work site and establish neither ordnance contamination of every property in Saarland nor any statement about areas already investigated technically.
The specific property and the available findings
A city’s name or previous industrial use alone does not establish ordnance contamination of a property. We consider the specific area and the available records. This distinguishes which indications of suspected ordnance require further investigation and which information is missing for a reasoned decision.
Requirements
Clarify technical requirements and responsibilities within the project
Relate requirements to the specialist task
For commissioned activities in Germany, the relevant technical requirements and questions of permits, certificates of competence and responsibility are clarified. The actual scope of services planned is decisive. Permits and certificates of competence are assigned to the specific tasks and interfaces. The companies involved coordinate the necessary specialist work with the planned construction services.
Link occupational safety to the construction sequence
Risk assessment, work areas and communication must suit the proposed activities. Ordnance specialist works are coordinated with the other construction activities. Operational organisation, traffic safety and other specialist technical inspections retain their own responsible parties. Joint coordination brings the information together without equating the different tasks.
Use technical findings correctly
A measurement anomaly first requires specialist assessment; its appearance alone does not identify it as explosive ordnance. If an object is genuinely suspected to be ordnance, the prescribed reporting procedures and the measures set by the responsible authorities apply. Investigation reports specify the work completed and its limitations, so that results are not extended to unexamined areas or later design changes.
Local background: BFR KMR: procedure in Saarland.
Planning and documentation: BFR KMR: clearance planning · BFR KMR: geophysics · BFR KMR: documentation. Outside their scope relating to federal properties, the BFR KMR provide technical guidance; local requirements remain separately applicable.
Permits, certificates of competence and responsibility are assessed for the specific activity under the Explosives Act and the First Ordinance to the Explosives Act. The risk assessment under Section 5 of the Occupational Safety and Health Act relates to the planned activities. The DGUV Information 201-027 addresses the preventive investigation and clearance of conventional explosive ordnance and defines its scope. Its references to DGUV Regel 113-003 concern specific activities involving explosives; they are not applied indiscriminately to every construction investigation.
Working together
Distinguish the tasks of client, designers and specialist contractor
Client and operator
The project owner describes the project and provides the available records. Operators add information on use, access and timing requirements. A coordinating contact brings the information together; the parties agree their respective tasks and decision-making interfaces. Before commissioning, it is clearly recorded which information is missing, who will obtain it and which next construction decision the result is intended to inform.
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 specialist ordnance contractor carries out the agreed research, investigation and documentation within the required scope of permits and certificates of competence. In Saarland, the responsible police authorities arrange the hazard response when ammunition is found. Within its remit, the state ordnance disposal service handles wartime ammunition found, including recovery, rendering safe, transport, temporary storage and destruction. The specialist contractor and project team coordinate any necessary handovers with the responsible authority in good time. The technical report remains linked to its treated area and specialist task.
Investigation task
Which specialist task comes next?
Relate the method to the investigation objective
The information needed depends on the planned ground interventions and existing findings. Specialist planning assesses suitable methods and actual measurement conditions. Structures in the ground, terrain and interference are taken into account. The achievable limits should be clear at the coordination stage so that the commission addresses a specific question that can be investigated under these conditions.
Compare suitable specialist servicesDistinguish specialist investigation from hazard response
For construction work that can be planned, the investigation scope, prerequisites and handover of results are agreed. If a suspicious item is actually found, protective measures and reporting procedures take priority: the responsible police authorities arrange the necessary hazard response and involve the state ordnance disposal service. The project team keeps these tasks and their respective responsible parties identifiable alongside the private investigation commission.
Compare investigation methodsRegion and construction task
Industry, transport routes and redevelopment sites in Saarland
On a former industrial site, foundations can interfere with measurements. In a confined built-up area, access and available working space can limit the investigation. Such conditions are clarified before the investigation.
We handle enquiries from the Regionalverband Saarbrücken and the districts of Saarlouis, Neunkirchen, Merzig-Wadern, St. Wendel and Saarpfalz-Kreis. Examples include Saarlouis, Homburg, St. Ingbert and Merzig. The work required is assessed for the individual property and construction project.
Industrial land and former business premises
During changes of use around Saarbrücken, Völklingen or Neunkirchen, former industrial structures meet new construction tasks. Utilities, foundations and metal structures can influence measurements. Historical indications of ordnance are therefore assessed separately from mining, ground engineering and contaminated land issues; the specialist planning disciplines are coordinated.
Transport routes and densely built-up areas
Railway corridors, roads, utility networks and urban excavations require planning by section. Accessibility, ongoing operations, neighbouring buildings and the actual depth of ground intervention influence the investigation grid and construction sequence. A result for a utility trench cannot automatically be transferred to the adjoining area.
Redevelopment sites and border areas
For former military sites and indications of combat, the history of use and available sources are decisive. A site-specific assessment is also useful outside large towns and cities. Previously undeveloped land is, for that reason alone, neither suspect nor demonstrably free of ordnance.
Tasks at the site
Relate existing assessments to the specific groundworks
01
Establish a clear location reference
Show the property affected with its boundaries and the ground disturbance actually proposed. A shared file reference helps assignment but does not replace a complete spatial description. Preparatory works and additional construction areas also belong in the comparison.
02
Distinguish requirements from results
An assessment may identify further work required. Check which tasks have already been documented as completed. Keep the corresponding reports and appendices available. A stated requirement and evidence that it has been fulfilled are different parts of the project information.
03
Define construction phases traceably
Determine which next work needs a conclusion. Different sections may have different access and depths of ground disturbance. Keep the investigation status separately identifiable for each area, even where commissioned together.
04
Compare new plan revisions selectively
Mark changes from the project already considered. Additional areas, greater depths or different preparatory activities may require a fresh comparison. Existing results are considered within their actual scope.
Investigation and clearance
Services for preliminary investigation, surveying and clearance
Not every project needs all methods. We first review the available indications and planned work. This determines which investigation is suitable for the work site and the depth required.
Historical aerial photograph analysis
Aerial photographs, maps, former uses and existing reports are examined for indications relevant to explosive ordnance. The assessment identifies the sources examined, their spatial reference and remaining uncertainties.
Surface survey
Magnetometry, TDEM or ground-penetrating radar are selected according to ground conditions, sources of interference and the investigation objective. A measured anomaly is initially a finding to be assessed, not a positively identified explosive ordnance item.
Deep-ground and downhole surveys
For deep foundations, retaining structures or other deeper ground interventions, we assess whether surface measurements can provide the information required. If this is insufficient, a coordinated investigation at depth may be considered.
Area clearance
For defined suspected areas, the area to be treated, clearance objective and necessary work steps are established. Investigation results and identified limitations determine which further measures are required.
Excavation supervision
Specialist support during earthworks can form part of the agreed approach. It requires defined work sections, clear reporting procedures and an appropriate construction sequence; it does not replace necessary preliminary investigations.
Investigation of findings and explosive ordnance recovery
When items are actually found, tasks and handover are clarified with the responsible authorities. The specialist contractor’s activities depend on the commission and its powers. State hazard response remains a separate responsibility.
Project types
Determine the service required from the project and the available findings
Assess historical records and existing reports
Collect findings relating to the affected area and include the current plans for ground interventions. The assessment distinguishes historical indications, investigations already carried out and outstanding questions. Former uses can provide important clues. However, the further scope required is related to the specific property and is not inferred solely from a general area designation.
When a former industrial site is repurposed, the business considered in the records may have extended beyond the present property. Mark old boundaries of use, available site plans and known alterations. A historical assessment is read with its sources and temporal limits. For the new ground intervention, it is then stated which findings are usable and which specific question still needs investigation.
Relate existing reports to the ground disturbance
Plan a suitable investigation for the works in the ground
Specialist planning takes account of the investigation objective, terrain, existing structures and achievable access. Planned construction phases are coordinated with the services required. Where conditions are restricted, the limits remain explicitly identifiable. A particular method is not chosen solely from the town’s name or the industry, but from the information needed and the actual conditions at the work site.
Also identify working space, utility connections and temporary excavations. Where several contractors are involved, it is recorded who provides the current geometry and who passes changes to specialist planning. For residential developments, the records are assigned to individual work sites and construction phases. A construction section may include different depths or interference conditions. The investigation boundary is therefore aligned with the specialist information needed and linked transparently to the execution sections.
Compare specialist servicesMake results available with their scope of validity
The conclusion describes the areas treated, methods used and remaining limitations. Results are assigned to the planned ground works. Changes to the construction area or depth require a new comparison. Documentation thus supports subsequent decisions without extending a partial report into an unlimited statement about the whole property or all later uses.
The version of the plans used and all appendices are kept together in the project file. Identify the next ground work for which the result is intended. If execution takes place later, changed levels, additional trenches or shifted points are compared specifically. This gives the project owner and site management a traceable basis for outstanding tasks and questions to the specialist contractor responsible.
Document findings and their limitationsProject documents
Documents that establish the next step
Describe the first ground intervention in full
Site investigations, utility diversions or preparatory excavations may be due before the main excavation. Record these works with location, depth and date. The necessary specialist clarification is planned before the relevant intervention. A later main investigation commission does not automatically answer retrospectively the question of earlier works in the ground.
Where area clearance is required, the treatment objective, spatial scope and interfaces for handling finds are defined in the technically agreed approach. Clearance work carried out is recorded in a clearance log with the areas treated and limitations identified. This is kept in the project file with the associated drawings; outstanding subtasks remain identifiable.
Identify project participants and their tasks
The project owner, designers, specialist contractor and site management need different information for their work. Agree the respective handovers and contacts. Other technical specialists and the authorities’ tasks remain taken into account. Joint coordination makes interfaces traceable without treating a commissioned investigation as approval or responsibility for all other project issues.
Method selection
Select methods according to the task and survey conditions
Historical records and aerial photographs
For preliminary investigations, available aerial photographs, maps, land-use records and earlier reports are brought together. Their dates and area references must match the construction area considered. Where historical questions remain open, the necessary source research and aerial photograph assessments are actually carried out. The absence of a recognisable historical finding remains distinct from a technical investigation of today’s ground. For an altered industrial site, old business boundaries, present parcels and documented earth movements are considered together. The assessment identifies the data used, indications of suspected ordnance and gaps for further investigation planning.
Understand aerial photograph assessmentMagnetometric survey
Magnetometry passively detects anomalies with a magnetic effect. Conductivity alone does not make an object detectable by this method. On former industrial sites, foundations, reinforcement, fences and existing utilities can influence measurements. Specialist planning clarifies whether the information needed can be obtained under the actual conditions. Recorded signals are assessed with their position and sources of interference. A strong anomaly is examined further by specialists and is not classified as explosive ordnance solely from its signal strength.
Understand the scope of magnetometryElectromagnetic methods
Time-domain electromagnetic methods, or TDEM, investigate the electromagnetic response of conductive objects over time. Specialist selection considers the expected target objects, volume of ground and interfering structures. Different measurement conditions may exist along a utility route between open ground and a connection among existing structures. These differences are taken into account in planning and data assessment. Results are given a traceable spatial reference. Additional measurements are determined from an outstanding investigation question; having a device available determines neither suitability nor the scope required.
Understand electromagnetic surveyingGround-penetrating radar
Under suitable conditions, ground-penetrating radar provides information on structures and reflections in the subsurface. Ground composition, moisture and structures in the ground influence penetration and interpretability. For made ground and changing strata, the extent of achievable interpretation is assessed for the specific task. Specialist interpretation links the radar image with other findings and records limitations. An anomalous reflection pattern does not by itself identify explosive ordnance. A survey made for utility detection or ground engineering questions is checked against its commission and limitations for usability in the ordnance assessment.
GPR and limitationsDeep-ground and downhole surveys
For deep foundations, drilling or retaining structures, the volume of ground actually required is first described. If investigation from the surface cannot provide the information needed, a suitable deep-ground or borehole survey is planned. Point location, reference level, borehole path and existing utilities form part of preparation; creating investigation access must also be coordinated technically. The documentation or borehole clearance remains tied to the volume investigated. Shifted starting points or greater intervention depths are compared with this scope before execution. General depth statements or standard grids do not replace this check.
Prepare deep interventionsSurvey during construction
An ordnance investigation during construction is planned by specialists if the necessary advance investigation cannot be completed in full and this approach is suitable for the task. It may include excavation in layers, specialist exposure and supplementary surveys within the planned working area. Investigation, assessment and communication of findings are coordinated with the construction sequence. Visual observation of excavation alone is not sufficient as detection. Site management receives the prerequisites for the next ground work; areas treated, limitations and outstanding tasks are documented. If an item is found, the responsible authority is involved through the agreed reporting procedure.
Agree the approach during constructionTechnical assessment
Distinguish historical assessment from technical investigation
Understand the historical findings available
Existing aerial photograph assessments and official statements are read with the current ground disturbance plan. Their tasks and spatial coverage remain identifiable. Technical planning builds on these findings and describes the further conclusion needed for the proposed groundworks.
Consider measurement conditions in specialist planning
Available access, installed structures and local interference affect the investigation. The appropriate approach is matched to the investigation objective. An earlier method or general area name does not automatically determine the method for a new task.
Identify the remaining needs specifically
Areas not sufficiently covered remain documented as outstanding tasks. Supplementary steps receive a defined spatial and technical scope. A partial report thus becomes usable for further planning without extending its conclusions to areas not yet investigated.
Next steps
From the current plan to documented investigation
Collect documents and plan versions
Provide assessments, existing reports and current plans for ground disturbance with their appendices. Identify unclear spatial references and missing documents. The initial discussion identifies the project location and the findings needed. Existing plans, statements and reports are checked for currency, spatial relevance, completeness and gaps.
Address outstanding historical questions
Where historical questions remain open, necessary research and aerial photograph assessments are actually carried out within the commission agreed by specialists. Existing assessments are considered with their respective subareas and conclusions. Additional findings are assigned to the present area of ground disturbance and used in investigation planning.
Define the next specialist task
Describe which findings are needed for which ground disturbance. Investigation scope, prerequisites and the parties' duties are agreed clearly. A suitable method is selected according to the investigation objective, depth of ground disturbance, ground composition, existing structures and actual measurement conditions. Access and necessary prerequisites are clarified with the parties responsible.
Check the prerequisites for execution
Clarify access, construction phases and necessary notifications before the planned start. Pass on planning changes to the affected parties in good time.
Perform the agreed investigation
The agreed survey or appropriate investigation during construction is carried out on the defined areas and points. Measurement data and observations receive clear position and elevation references. Uninvestigated areas, restricted access and relevant interference are recorded.
Assess and document findings
The collected data and findings are assessed against the investigation objective and actual measurement conditions. The assessment takes account of interference and limitations. The report and plan appendices document the technical assessment, areas addressed and their position, elevation and depth references. Required further tasks follow from this.
Pass on the complete results
Reports and site plans show the work actually completed. Areas still outstanding or subject to limited interpretation remain clear for the next works.
Construction sequence
Coordinate investigation and construction sections
Make a specific enquiry using the records available
Provide the site plan and planned ground works with depth information. Include existing reports, historical assessments and known obstacles. Information still missing can also be identified openly. The first discussion clarifies which statements are already usable and which further records or specialist services are needed for the particular construction task.
Define the commission and its handovers clearly
Record the investigation objective, area, prerequisites and required handover of results. Specialist work is coordinated with construction phases and contacts. After completion, the results are handed over in full to designers and site management. Outstanding areas remain marked and are addressed specifically before the related works, rather than being treated as complete through a general project confirmation.
Responsibilities and documentation
Clarify responsibilities and documentation before execution
Before work begins, it is agreed which investigation will take place, who needs its results and how anomalies are to be handled.
Tasks of the specialist contractor, police authority and ordnance disposal service
In Saarland, the local police authorities and the ordnance disposal service are involved in responding to ammunition finds. The state procedure set out in the Baufachliche Richtlinien Kampfmittelräumung distinguishes commissioned preliminary investigations and surveys by specialist contractors from the state service’s handling of ammunition identified in finds.
For your project, we record which areas and depths will be investigated, who needs which records and which coordination is required before work starts. If the construction sequence changes or works go deeper, it must be checked whether the previous investigation is still sufficient.
The final report assigns results to the areas treated. Methods, findings, limitations and outstanding questions remain identifiable. Specialist clearance or a statement on further work relates to the scope described; it is not an unrestricted assurance for the entire property.

Findings and their scope
The investigation report describes the specialist service carried out, including area, depth, method and remaining limitations. The next works in the ground are compared with this scope. Existing results thus remain usable while outstanding tasks remain identifiable for designers and site management.
Project responsibilities
In Saarland, the local police authority is responsible for hazard prevention at the lower administrative level. If there is imminent danger and it cannot be reached in time, the police act within their supplementary remit. The state ordnance disposal service may be involved for support. The planned private investigation has its own agreed scope, documentation and interfaces with the responsible authorities alongside this.
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.
Technical principles
Involve the responsible authorities for the project in Saarland
The state procedure describes the authorities’ responsibilities. The steps required for your project are clarified using the available records and in consultation with the responsible authorities.
Understand the results
Use technical statements for the next decision
Review an existing report in full
Read the investigation purpose together with the maps, depth reference and limitations. Compare this with the current construction plans. An older report may remain usable if its scope fits; its age alone does not determine a new investigation commission. Missing appendices or unclear area assignments are identified and clarified before further use.
Understand investigation reports and their limitationsMake changes visible before execution
New trenches, different foundations or shifted construction boundaries can change the scope of information needed. Pass on these changes with the current version of the plans. Specialist planning checks existing results against them and identifies supplementary tasks where necessary. The connection between the area investigated and the ground intervention actually planned thus remains traceable as the project progresses.
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.

Determine the specialist service from the planned groundworks
Historical assessment, technical investigation and further work are distinguished according to the outstanding task. Describe whether historical information is missing, a particular volume of ground is to be investigated or an assessed finding needs further clarification. The appropriate service is coordinated with the ground intervention and expected results documentation.
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 explosive ordnance assessments in Saarland
Is a report from an earlier construction project sufficient?
An existing report is an important starting point. Whether it covers the new works depends, among other things, on the area boundaries, investigation depth, methods used at the time and the works now planned. We check this correspondence using your records.
How does an explosive ordnance assessment differ from a contaminated land investigation?
An explosive ordnance assessment addresses possible explosive remnants of war. A contaminated land investigation assesses other forms of contamination, such as chemical pollutants. Both issues can arise on former industrial sites; their results do not replace one another.
Which documents help with an enquiry?
Send a site plan showing property boundaries, the nature and depth of the earthworks, existing aerial photograph assessments or ordnance reports and your programme. Utility plans and information on accessibility or ongoing operations help us prepare.
Does every project need all the methods offered?
No. Specialist planning determines the services required from the specific ground interventions, existing findings and actual investigation conditions.
What determines the cost of an ordnance assessment?
The work required depends on existing findings, area size, intervention depths, a suitable method, access, interference and the results documentation needed. Also clarify any preliminary works and interfaces required. Private preliminary investigations and surveys are considered separately from the response to a find, with their respective responsibilities for costs; state handling of a find does not mean that all construction preparation is free of charge.
What happens if the construction plans change?
The new areas and depths are compared with the documented investigation scope. Outstanding questions are clarified before the relevant ground intervention.
What should site management receive with the report?
The associated maps, references to area and depth, recorded limitations and outstanding tasks, linked to the current version of the plans.
What should you do if a suspicious object is found?
Stop work in the affected area. Do not touch, move or relocate the suspicious object, and do not expose it further. Leave the danger area, keep others away and immediately notify the police on 110 from a safe distance. Do not take the object to a police station. Follow the instructions of the responsible authorities.
Project enquiry
Your records for an explosive ordnance assessment in Saarland
Describe the project
Bring together the site plan, ground works and depths for the enquiry.
Add the municipality concerned, plot numbers, reference levels and programme. Mark the first planned intervention, including preparatory utilities, site investigations and excavations. Utility plans, available access and ongoing operations form part of the enquiry, as do options still under consideration. The agreed scope can thus be related to the information actually needed and the areas that can be reached.
Send existing findings
Include reports with appendices, access details and known obstacles.
Provide aerial photograph assessments and technical reports in full, with maps, legends and appendices. Identify their date, publisher and areas investigated. Work actually carried out is identified with its results documentation. Missing appendices, inaccessible parts of the site and unclear references are stated. If the parties involved change, it remains clear who passes on the common version of the plans and the complete investigation status.

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.
