Concrete scanning and GPR in Dubai and across the UAE.
This article explains the planning question. For scope review, method selection and a site-specific technical proposal, continue to Arasar's primary service page.
Start with the planned work and its location
Send a marked drawing showing the proposed cutting, drilling or removal area, not just the site address. Identify the slab, wall, beam or other element and include the drawing revision. If positions are provisional, label them so the survey scope is not mistaken for an approved opening layout.
Explain what decision the scan should support. Locating reinforcement around a bore, investigating a wall opening and asking about concrete thickness are different questions. A clear brief helps the specialist determine whether the requested answer is achievable and what additional information may be needed.
Distinguish the survey objectives
Use the enquiry to separate what must be investigated from what has already been assumed. Describing every requirement as a general GPR scan can leave differences in the proposed coverage and deliverables.
| Project question | Information to provide | What to clarify |
|---|---|---|
| Rebar or tendon layout | Marked proposed opening and structural drawings | Which layers and surrounding area need interpretation? |
| Concealed services | Known routes, MEP drawings and receiving-side access | What can the selected method identify and what remains uncertain? |
| Slab or wall thickness | Element, access and required measurement purpose | Can the method resolve this under the actual conditions? |
| Repeated openings | Opening schedule and unique location references | How will findings be tied to each opening? |
| Recorded evidence | Required drawing format and project references | Are markings, annotated plans and a report all included? |
Agree limitations before interpreting a clear result
Hilti describes radar-based detection of embedded objects and the export of scan information for further analysis. Its published equipment capabilities are not a universal guarantee for every structure or a claim that Arasar uses that model on every job. The actual survey proposal should state its method and limitations.
Ask what the records mean where access, coverings, congestion or other site conditions limit interpretation. An area with no reported object is not automatically a verified safe cutting zone. The findings must be considered alongside drawings and the responsible engineer’s decisions.
Prepare access and an identifiable survey area
Photographs should show the surface to be scanned, nearby obstructions and access to the opposite face where available. State the floor level, finishes that must remain, working windows and any occupied areas nearby. Identify who will arrange access and any permitted preparation.
Keep a stable reference between the marked drawing and the site. A room number, grid reference or opening ID is more useful than a photograph without context. If the opening moves after the survey, ask the project team whether the new position is covered by the existing evidence.
- Location, element and opening references
- Available structural and MEP drawings
- Visible surface condition and access photographs
- Known occupancy and working-hour restrictions
- Required record format and decision date
Specify markings, records and the handover decision
Agree whether the package includes site markings, annotated drawings, images, an interpretation report or a combination. The useful handover connects the findings to an identifiable area, records limitations and tells the receiving team which questions remain open.
Do not confuse data collection, interpretation and structural acceptance. Clarify who receives the survey, who checks it against the design and who releases the opening for the next trade. Scanning and cutting may be coordinated within one project, but they remain different decisions.
Compare quotations against the same survey brief
Compare the defined area, access assumptions, deliverables and exclusions rather than the price alone. Check whether return visits, changed locations or additional reporting are included. A lower price may refer to a smaller investigation area or a different handover.
For Arasar’s concrete scanning service in Dubai and across the UAE, send the marked work area, available drawings, photographs and the outcome you need. Where information is missing, identify it explicitly so the proposal can separate confirmed scope from the questions requiring a site review.
Frequently asked questions
01Does GPR scanning confirm that a structural wall can be removed?
No. It provides investigation data. The opening or removal still needs the responsible team’s structural assessment and the applicable project approvals.
02Can concrete scanning measure slab thickness?
It may support a thickness investigation where the selected method and site conditions permit. State the required measurement in the enquiry and request its limitations rather than assuming it is included in any scan.
03What is the difference between concrete scanning and ground utility scanning?
They concern different survey environments and objectives. Specify whether the work relates to a concrete element or buried utilities before excavation; do not treat equipment ranges or survey outputs as interchangeable.
04What should a scanning quote include?
A defined survey area, access assumptions, objectives, method, limitations, deliverables and exclusions. Clarify how changed openings and return visits will be handled.

Project note
Guidance is the starting point. The site determines the method.
Every structure, access route and operating environment is different. Final engineering, approvals and controls should be based on verified project information and a site-specific assessment.
