What actually drives the cost of a GPR scan in Dubai

Ask three companies to price a concrete scan in Dubai and the numbers can differ by a factor of several. That usually is not because one is overcharging — it is because the three of them have priced three different jobs. Scanning scope is easy to describe loosely and expensive to get wrong.

Here is what genuinely moves the price, so you can define the scope well enough to compare quotes properly.

Area, not the number of holes

The intuitive assumption is that ten penetrations cost twice five. In practice the driver is the area scanned, not the hole count. Clearing a single position still means scanning a zone around it, so one isolated core in a large floor plate can cost more than twenty holes clustered in one bay.

If your penetrations are grouped, say so when you ask for a price. Grid scanning a defined zone once and marking every position within it is considerably cheaper than treating each hole as its own visit.

Mobilisation and access

Getting to the slab is a real cost. A ground-floor warehouse in Al Quoz with a roller door and a parking space is a different job from level 34 of a Business Bay tower where equipment goes up in a goods lift booked in advance. High-rise work, restricted access and long carry distances all add time before any scanning happens.

Multiple sites in one area can share a mobilisation. Contractors running work across Al Quoz, DIP and Jebel Ali often sequence several sites into one visit, which is cheaper than three separate callouts.

When the work has to happen

A significant share of Dubai scanning is in occupied buildings — trading malls, live hotels, working offices — and has to happen outside operating hours. Night and early-morning work carries a premium, and where the building requires a permit or a security escort that adds time too.

If the work can be done in normal hours, it will be cheaper. Where it cannot, factoring that into the enquiry avoids a quote that changes once we learn the constraint.

What you need at the end

Marking positions on the slab so the cutting crew can work is one level of output. A formal PDF report with annotated layouts, submitted to a consultant for approval, is another. 3D rendered data, or CAD and GIS deliverables for a project team, is another again.

None of these is unreasonable, but they are different amounts of work. Saying up front what the consultant or the permit process expects prevents a mismatch between what you were quoted for and what you actually need.

Urgency

Same-day attendance is often possible and it is priced accordingly, because it means rescheduling other work. If your programme allows a day or two of notice, you will usually pay less. Where a permit to work is involved — common on Abu Dhabi and government projects — the approval process, not our availability, is normally the constraint anyway.

How to get a quote that holds

• The site address, and which floor
• Roughly how large an area needs scanning, and whether penetrations are clustered or spread out
• What the element is — suspended slab, ground-bearing slab, wall, column
• Whether the building is occupied, and whether work must be out of hours
• What documentation you need at the end
• Your date, and whether a permit to work applies

A quote given without these details is a guess, and guesses get revised on site. Six lines in a WhatsApp message is usually enough for a number that holds.

One thing we will not do is quote a scan and then cut without it. Scanning before coring is not an upsell in our pricing — it is the sequence we work to, because the cost of a strike falls on the project long after the invoice is settled.
