Concrete Scanning Cost in Melbourne: What Drives the Price

A concrete scan is priced by the job, not by a fixed rate per slab. The total depends on how much area you need cleared, how many locations there are, how hard the site is to reach, which method is used and what you want handed back (spray marks on the slab, photos or a written report). We don’t publish a flat scanning price, because two jobs that look alike on paper can differ a lot on site. This guide shows you what sits behind a quote, so you can compare quotes properly and budget with confidence.

TL;DR

• Scanning is quoted per job. Area, number of locations, access, method and reporting are the main price drivers.
• Ground penetrating radar (GPR) is the usual method for slabs and walls before cutting or coring. X-ray is a specialist option with extra licensing and safety controls.
• A scan is a small line in a budget compared with striking rebar, a conduit or a post-tension cable.
• When you compare quotes, check what is marked on the slab, what depth the operator can reliably read and whether the scan is bundled with the cutting or coring.
• Vic Sawing & Drilling scans and cuts across Melbourne and Victoria, and we quote free.

What a concrete scan is and why it gets a line in the budget

A concrete scan locates what is inside a slab or wall before anyone cuts, drills or cores it. That usually means reinforcing bars, electrical conduit, pipes and, in some buildings, post-tension cables. The operator marks the findings on the surface so the cut or core can be placed clear of them.

You are paying for risk control. Hitting a conduit can mean a power outage and a repair. Cutting a tensioned cable can damage the structure and put people at risk. Hitting rebar with a core bit wears out diamond segments and stalls the job. Our guide on how to avoid rebar when drilling concrete covers what that looks like on a real job, and our piece on why GPR concrete scanning matters explains the technology in more detail.

How concrete scanning is priced

Operators price a scan in one of three ways, and many combine them.

1. A minimum call-out. Small jobs, such as scanning for two or three cores in an office slab, usually carry a minimum charge that covers travel, setup and a short time on site. The cost per hole is highest on very small jobs for this reason.
2. Time on site. Larger or more complex jobs are often priced by the hour, half day or full day, with the operator’s time and the scanner included.
3. Area or location count. Some quotes are built from the number of slabs, walls or grid areas to scan, which suits repeated work such as a floor-by-floor fit-out.

A fourth path is bundling. When the scan is followed by cutting or coring by the same crew, the scan is often folded into the job price. On our own work, a scan before cutting or coring is part of the planning, and we are happy to explain in the quote what is included. Our published starting range for concrete cutting is $450 to $5,000 per one-off job, which gives you a sense of how the work around a scan is scaled. Scanning itself is quoted to your site.

What affects the cost of scanning a slab

These are the factors that move a quote up or down, in rough order of impact.

Area and number of locations

Scanning a 1 m² patch for a single core is a different task from mapping a whole warehouse floor before saw cuts. More area means more passes in a grid pattern, more marking and more time. Several separate locations in one building add walking, setup and access time.

Access and site conditions

A clear ground-floor slab is quick. A ceiling, a wall behind shelving, a plant room or a basement with limited lighting takes longer. Rough, wet or heavily finished surfaces such as thick coatings, tiles or screeds can slow the work. Tight spaces affect the cutting and drilling stage too, which we cover in concrete drilling in tight spaces.

Depth and density of what is inside

Heavily reinforced slabs, double mesh layers, closely spaced bars and thick structural slabs are harder to read than a light residential slab on ground. Depth matters because the accuracy of any scanner falls as the target gets deeper. As one example of published figures, the Hilti PS 1000 X-Scan lists a depth accuracy of ±10 mm for targets under 100 mm and ±15% beyond that, a localization accuracy of ±10 mm, and a minimum distance of 40 mm between two neighboring objects. Those are specifications for one product, not a promise for every site, but they show why the operator keeps cutting lines a safe margin away from marked objects.

Method

GPR is the standard for most slab and wall work. X-ray imaging is used for specific situations and carries additional compliance costs, covered below.

Reporting and deliverables

Spray or chalk marks on the surface are the baseline. If you also need annotated photos, a marked-up plan or a written record for an engineer or building certifier, expect that to add time to the quote. Tell the operator at the start who will use the results.

Timing and urgency

After-hours work in occupied buildings, same-day bookings and work in busy live sites change the price. If you can book ahead and give a clear window, you give the operator room to schedule efficiently.

Travel

Melbourne metro jobs and regional Victoria jobs travel differently. If you are outside the city, the quote may include travel time. We service Melbourne and all of Victoria, including Richmond, Werribee, Sunbury and Cranbourne.

Quote scenarios to help you budget

The table shows how the factors combine on typical jobs. It describes what drives cost, not a price list.

The quickest way to pull your own cost down is to give accurate information up front: photos, the slab type if you know it, any drawings and the exact positions you want to cut or core.

GPR versus X-ray: how the cost compares

Most clients ask about X-ray because they have heard it gives a clearer picture. It is a legitimate method, but it is used for a narrower set of situations, and it brings regulation with it.

GPR sends radar pulses into the concrete from one side and reads the reflections. It is portable, quick and does not use ionizing radiation, which is why it is the default for slabs, walls and columns before cutting and coring. X-ray imaging passes radiation through the member and needs access to both sides, with an exclusion zone around the work and trained, licensed operators.

That licensing is a real cost behind the method. For reference, the NSW EPA lists radiation user licence fees for Group 3 regulated material, which includes radiation apparatus used for industrial radiography, at $295 for a 1-year licence and $607 for a 3-year licence, with a further $276 fee for non-standard applications referred to the Radiation Advisory Council. That is the New South Wales schedule. Other states set their own arrangements, so if X-ray is on the table for a Victorian job, ask the operator to confirm the licensing and safety plan that applies.

In plain terms, X-ray work is typically priced above GPR work because of equipment, licensing, safety controls and the need for access to both sides. Our comparison, GPR vs X-ray in Australia, walks through which method fits which situation. For routine pre-cut scanning, GPR gives you the information the crew needs at a lower cost and with less disruption on site.

What the scan will and will not tell you

A good scan answers specific questions: where the top layer of reinforcement runs, where conduits sit, whether post-tension cables are present and, within the limits of the method, how deep things are. It is a planning tool, and the operator reads the result with the construction type in mind.

There are practical limits to keep in mind when budgeting:

• Accuracy declines with depth, as the published specifications above show.
• Closely spaced objects can blur together, so the operator keeps clearance from marked lines.
• Wet concrete and dense reinforcement make interpretation harder, and the operator may need more time or a second method.
• The scan shows what is in the area scanned. If your cut line or core position moves, ask for the new position to be scanned as well.

This is why we plan scanning and cutting together: the person who marks the slab is working with the crew who will make the cut.

Getting a quote you can compare

When you collect two or three quotes, line them up on the same basis. Ask each operator:

1. What area and how many locations are covered? A lower price for a smaller area is not cheaper.
2. What is marked on the slab, and what will you receive afterward? Surface marks only, photos or a written record.
3. Is the scan bundled with the cutting or coring? If so, is it itemized.
4. What is the minimum charge and what happens if the job runs over?
5. Who holds the licences and insurances, and what is the safety plan? For OH&S, you want to see licensed, qualified operators following safe work procedures.
6. What access do they need? Power, lighting, clear floor, both sides of a wall.
7. How soon can they start, and is after-hours work available?

For wider budgeting on a cutting or demolition project, our Melbourne concrete removal cost and quote checklist covers waste rules and the line items to look for. Coring is commonly priced per core, and a breakdown of coring unit prices by slab shows why a single rate rarely fits every slab, which is exactly why we ask about your slab before giving a number.

Preparing the site so the scan is quick

Preparation is the cheapest way to trim a scanning bill, because time on site is the main variable. Before the operator arrives:

• Clear the area. Move furniture, stock and equipment away from the slab or wall.
• Mark your intended positions. A simple sketch or tape marks showing where you want to cut or core saves back-and-forth.
• Gather drawings. Structural or services plans help the operator cross-check what the scan shows.
• Confirm access and power. Lift access, parking, loading dock times and building induction requirements.
• Tell us about the structure. If you know a slab is suspended, post-tensioned or recently renovated, say so.

If you manage a building, tell the operator about tenants, noise limits and hours at the time of booking so the work is scheduled around them.

Our perspective

We see the cost of scanning from the other end of the job: the crew that has to make the cut. A scan that is rushed or skipped rarely saves money. It moves the cost to a damaged conduit, a stalled core bit or a redesigned opening.

That is why we treat scanning as the first step of the cutting and drilling process rather than a separate product. Our licensed and qualified operators follow OH&S safety standards, and we use modern equipment on everything from a single domestic core to large commercial and industrial projects. When the person who scans the slab is working with the team that will cut it, the markings fit the method, the cut lines are placed with the right clearances and fewer questions are left for the day of the job.

We would rather give you a clear quote on the scope than a number that looks low and grows later. Tell us what you are cutting, where and why, and we will explain what the scan covers and what comes after it.

FAQ

How much does a concrete scan cost in Melbourne?

It depends on the area, number of locations, access, method and reporting, so scans are quoted per job. Small jobs usually carry a minimum call-out, and larger jobs are priced by time on site or by area. We provide free quotes, and the more detail you give us, the tighter the number.

Is concrete X-ray scanning more expensive than GPR?

Generally yes. X-ray needs access to both sides, an exclusion zone, trained licensed operators and a safety plan, all of which add to the cost. GPR is portable and suits most slabs and walls before cutting or coring.

Do I need a scan before coring a small hole?

Yes, it is good practice for any hole in a slab or wall, however small. A scan locates reinforcement, conduit and, in some structures, post-tension cables, so the core can be placed clear of them. It is quick on small jobs and avoids a much larger repair.

Is a scan cheaper when booked with cutting or coring?

Often, yes. One crew, one mobilization and one set of access arrangements keep time on site down. Ask for the scan to be shown as a line in the quote so you can see what is included.

Can I scan my own slab with a hired scanner?

Scanners are specialist instruments, and reading the results takes training and experience with different slab types. For anything that will be cut or cored, we recommend having a licensed, qualified operator scan and mark it, then carry out the work as one planned job.
