UNDERGROUND UTILITY SURVEYS
Underground utility detection and mapping in Saudi Arabia.
Understand the buried-service information. Plan the next step with clearer records.
Review existing utility records and investigate detectable buried services within an agreed site area. Professionals Arabia, based in Riyadh, supports underground utility survey requirements for construction, infrastructure and facility projects across Saudi Arabia.

CONNECT EXISTING RECORDS WITH SITE EVIDENCE
Build a clearer picture of the services below the surface.
Existing drawings may show expected routes without fully representing current site conditions. An underground utility survey brings available records, visible features and appropriate detection methods together to document the evidence available within a defined area.
The scope should identify the work zone, services of interest, access conditions and outputs needed by the project team. We help define these requirements and record detected features, uncertainties and coverage limitations. Survey findings support planning and further verification; they do not replace the site's authorization, isolation or safe-excavation procedures.
WHAT WE OFFER
Six survey scopes. One documented site assessment.
Select a scope to see its purpose and typical outputs. The final method and coverage depend on site conditions, target utilities and agreed project requirements.

Utility records review
Understand what the existing information can tell you.
Review supplied drawings, asset schedules and available utility information. Identify the survey boundary, expected services and discrepancies requiring investigation.
Typical use
Survey planning and defining information gaps.
Typical output
Source register, scope plan and questions for clarification.
Scope note: Supplied records are evidence inputs, not confirmation of current routes or operating status.
KNOW WHAT YOU WILL RECEIVE
Survey findings with a clear source and status.
Define the required files and evidence records before mobilization. Not every output is included in every survey.
| Deliverable | What to specify | Format |
|---|---|---|
| Utility plans | Specify area, identifiers, route presentation, legend and source status. | CAD or PDF as agreed. |
| Location and depth records | Specify coordinate reference, feature IDs and how estimated depths are reported where obtainable. | Agreed schedules or survey data files. |
| Method and coverage notes | Specify methods, accessible areas, collection date and relevant constraints. | Survey report or handover notes. |
| Follow-up information | Specify unresolved indications, unconfirmed routes and areas needing further verification. | Annotated plan and outstanding-information schedule. |
Agree the reference system, depth convention, evidence categories and acceptance requirements. Survey results describe the evidence obtained on the survey date, not a guarantee that every buried service has been identified.
FIELD METHODS AND INTERPRETATION
Match the investigation to the site and target.
No single method suits every utility and ground condition. The survey approach is selected around the available information and required outcome.
Records and walkover
Compare supplied information with accessible covers, chambers and other visible features. Opening or entering assets is included only with appropriate authorization.
GPR
Investigate subsurface reflections and interpret possible features in context. Conductive soils and other site conditions can restrict penetration and clarity.
Electromagnetic locating
Trace suitable signals on conductive services or tracer systems, using an appropriate agreed mode.
Survey referencing
Relate recorded indications to the project reference using the agreed positioning method.
Equipment, access, signal application and survey extent are confirmed for the assignment. Do not promise universal depth or accuracy.
From the utility brief to documented findings.
Define
Confirm the work area, purpose, available records and target services.
Plan
Agree access, methods, references, coverage and outputs.
Investigate
Carry out the accessible field survey within scope.
Interpret
Compare evidence, document uncertainty and identify follow-up needs.
Deliver
Provide agreed plans, records and coverage notes.
Utility information that fits the wider project.
Connected inputs

Clear evidence
Distinguish observed or detected information from assumptions and unconfirmed records.
Usable handover
Agree the plans and notes the receiving project team needs.

Underground utility survey FAQs.
Does GPR detect every buried utility?
No. Results depend on the ground, target characteristics, depth and access. Suitable methods can be combined, but some services may remain undetected or unconfirmed.
How deep can the survey detect utilities?
There is no fixed depth applicable to every site. Soil conductivity, moisture, antenna selection and the target affect the result. The achievable investigation is assessed for the assignment.
Can plastic pipes be located?
GPR may identify a suitable response from a non-metallic pipe where conditions permit. Electromagnetic tracing may be possible where a suitable tracer system exists. Neither approach guarantees detection.
Are reported depths exact?
Depth indications are method-dependent estimates unless established through a defined verification method. The report should explain the depth convention and relevant limitations.
Do you need existing utility drawings?
Share all available records. They help plan and interpret the investigation, but may be incomplete or outdated and do not replace field assessment.
Does the survey confirm that excavation can begin?
No. Survey findings are one input to the site's planning and authorization process. The responsible team must address owner coordination, permits, isolation and further verification where required.
Can you provide CAD and GIS outputs?
Specify the drawing format, coordinate reference, attributes and receiving system. CAD plans and GIS datasets can be defined as deliverables, with the source and uncertainty retained.
Are trial holes and utility diversions included?
Exposure, excavation, isolation, diversion and repair are separate activities unless expressly agreed. Their responsibilities and authorizations should be defined before those works proceed.
