The investment
In 2019, Icelabz invested £100,000 in a Faro Focus S350 terrestrial laser scanner plus a high-end workstation for processing.1 The investment was a bet: laser scanning was the future of measured building surveys, and we needed to be early.
This article shares the actual ROI numbers after 200+ projects (2019-2025), with the caveats about anonymisation and confidentiality.
The headline numbers
- Initial investment: £100,000 (scanner £60,000 + workstation £15,000 + training £10,000 + setup £15,000)
- Projects completed with the scanner (2019-2025): 215
- Revenue generated from scanner-enabled projects: £1.2m (anonymised, indicative)
- ROI over 6 years: ~12x (i.e. £1.2m revenue on £100k investment)
- Payback period: 14 months
The payback period is the key metric. 14 months from a £100k capital investment is excellent for a service business.
Why the ROI worked
Three factors made the laser scanner investment work for Icelabz:
-
Speed = more projects per year. A measured building survey that took 2 days on site with a total station took 4 hours with the scanner. The 1.5 days of saved site time meant we could take on 30% more projects per year with the same headcount.
-
Higher fees = better margins. A laser-scanned survey commands a 20-30% premium over a total-station survey. The premium reflects the higher deliverable quality (point cloud, BIM-ready) and the value to the client (faster delivery, more accurate).
-
New market = new clients. Laser scanning opened up the heritage, commercial fit-out, and FM handover markets that we couldn't serve with total stations alone. These markets are 30-50% higher margin than the residential market.
The combination of speed + premium + new market made the investment work financially.
The cost structure (anonymised)
For a typical 2026 measured building survey with the laser scanner:
| Cost component | Per-project cost (ex VAT) |
|---|---|
| Surveyor time (1-2 days) | £400-£800 |
| Scanner hire (depreciation + maintenance) | £100-£200 |
| Processing (point cloud registration, cleanup, slicing) | £200-£400 |
| Drafting (2D plans, Revit model) | £300-£600 |
| Quality assurance (spot-checks, traverse closure) | £100-£200 |
| Professional indemnity | £100-£150 |
| Total cost | £1,200-£2,350 |
| Typical fee (mid-tier commercial) | £2,500-£5,000 |
| Margin | ~50% |
A 50% margin is strong for a service business. The scanner investment increased both the volume and the margin.
The risks I underestimated
Three risks that I underestimated when I made the investment:
- Software costs. Faro Scene, Leica Cyclone, Autodesk ReCap, and CloudCompare Pro all have annual licence fees. Budget £3,000-£5,000 per year for software.
- Training time. Becoming proficient with the scanner and the processing software took 6 months, not the 4-6 weeks I expected. Budget 6 months of reduced productivity for a new surveyor to become fully proficient.
- Client education. Many 2026 clients don't know what a laser scanner produces or why it's better than a total station. Budget 10-15% of every project for client education (showing the point cloud, explaining the deliverable).
None of these risks were deal-breakers, but they should be factored into the business case.
The business case template
If you're considering a similar investment, here's a simplified business case:
- Current revenue per year (no scanner): £X
- Estimated scanner-enabled projects per year: Y
- Average fee per scanner-enabled project: £Z
- Scanner-enabled revenue per year: Y × Z
- Scanner-enabled margin: 50%
- Scanner-enabled contribution per year: Y × Z × 0.5
- Scanner cost (depreciation + software + training): £A per year
- Net contribution per year: Y × Z × 0.5 - £A
- Payback period: £100,000 / (Y × Z × 0.5 - £A)
- 5-year ROI: (5 × (Y × Z × 0.5 - £A)) / £100,000
A scanner pays for itself if the payback period is < 24 months and the 5-year ROI is > 5x.
When the scanner doesn't make sense
A scanner is not a good investment for:
- A sole trader with < 30 projects per year (the volume isn't there to justify the capital cost)
- A firm that focuses on small residential surveys only (the premium doesn't materialise)
- A firm that doesn't have a trained surveyor to operate the scanner (training is 6 months)
For Icelabz, the scanner was a clear win. For a small residential practice, it would be a clear loss. The decision is firm-specific.
What's next for the scanner
Icelabz is now considering a second scanner (handheld SLAM, GeoSLAM ZEB Horizon, ~£40,000) to expand into the lofts and large-floor-plate market. The ROI calculation is similar to the first scanner.
We're also watching the drone LiDAR market (DJI L2) for large external surveys. The 2026 entry price is ~£15,000, which is much more accessible.

What is the difference between 2D CAD and 3D Revit deliverables? 2D CAD (.DWG/.DXF) is flat line drawings showing geometry only. 3D Revit (.RVT) is an intelligent model where each element (wall, door, window, beam) carries physical and functional data. 2D is cheaper; 3D is required for BIM projects and FM handover.
What is the difference between RICS Band A and Band B? Band A: ±15-25mm (1:50/1:100 scale). Band B: ±50mm (1:200 scale). Most UK measured building surveys are Band B; heritage and tight-clearance work is Band A.
What is LOD 200 vs LOD 500? LOD 200: approximate geometry for early design. LOD 300: precise geometry for design and construction. LOD 400: fabrication-level detail. LOD 500: verified as-built for FM handover and digital twin.
Do I need a measured building survey for a building regulations submission? Yes — building control bodies require accurate existing-drawings to verify the proposal. The measured survey provides the baseline against which the proposed extension or alteration is checked.
Can a measured building survey be done with the occupants present? Yes, with some caveats. Occupants are usually asked to leave for a few hours while the surveyor sets up the scanner. Laser scanning is non-contact and quiet; the main disruption is the surveyor walking through the space.
What is the difference between a laser scan and a measured survey? A laser scan is the data-capture method. A measured survey is the deliverable. Most 2026 measured building surveys use laser scanning as the data-capture method and produce 2D plans, 3D models, and point clouds as deliverables.
How long does a measured building survey take? A typical 3-bed house takes 2-4 hours on site for a 2-person scanner team, plus 1-2 days for processing and drafting. Larger or more complex projects take proportionally longer.
Can the measured survey be done from the outside? Partially. External elevations can be captured from outside, but internal floor plans, sections, and ceiling heights require internal access.
What is the Icelabz standard deliverable? 2D DWG + PDF + E57 point cloud, with a Revit LOD 300 model as optional add-on. For heritage projects, additional HDR photographs and detailed ornamental record drawings.
How do I commission a measured building survey? The standard process: send a brief, receive a fixed-fee quote, verify surveyor credentials, arrange site access, site visit, CAD/BIM drafting, QA check, delivery. Most 2026 quotes are returned within 48 hours.
