When You Need Handheld 3D Scanning in Barnet
Use handheld SLAM scanning when you need:
| Scenario | Why Handheld? | | --- | --- | | Fast documentation | 10–20x faster than tripod scanning | | Complex interiors | Walk through without tripod setup | | Time-critical projects | Rapid capture with minimal disruption | | Refurbishment and extension | Accurate as-builts for design | | Heritage preservation | Non-invasive detailed capture | | Occupied buildings | Capture without disrupting occupants | | Tight or confined spaces | Where tripod setup is impractical |
Handheld 3D scanning is ideal for Barnet's mix of period properties, modern apartments, and commercial buildings where accurate as-built data is needed quickly and without disrupting occupancy.
Costs in Barnet/London (2025)
| Deliverable Type | Price Range | | --- | --- | | Day rate (handheld on-site) | £750–£2,500/day | | Point cloud only | £750–£1,250/day | | Point cloud + 2D CAD | £1,000–£2,000 per drawing | | Point cloud + Revit/BIM | £1,500–£5,000+ | | Small residential project | £500–£1,500 | | Large commercial or industrial | £3,000–£10,000+ |
Handheld SLAM scanning is typically on the lower end of day rates due to faster capture. Some providers charge travel based on postcode; many include it in London quotes.
SLAM vs Tripod Scanning
| Factor | Handheld SLAM | Tripod Scanner | | --- | --- | --- | | Speed | 10–20x faster | Slower setup and capture | | Interior access | Walk-through, no tripod needed | Requires stable tripod setup | | Occupied buildings | Excellent — minimal disruption | Good but more intrusive | | Accuracy | ±2–5mm (depending on hardware) | ±1–2mm (higher precision) | | Large open spaces | Good | Excellent | | Outdoor scanning | Good (with IMU correction) | Excellent | | Best for | Complex interiors, occupied sites, fast turnaround | High-precision surveys, clean environments |
For most Barnet projects — period houses, flats, occupied commercial spaces — handheld SLAM scanning provides the right balance of speed, accuracy, and minimal disruption.

Frequently Asked Questions
Q: When do I need handheld 3D scanning in Barnet?
You need handheld 3D scanning for accurate as-built documentation of period properties, complex interiors, occupied buildings, and time-critical projects in Barnet. It is especially useful for refurbishments, extensions, BIM modelling, and heritage preservation where tripod scanning would be impractical.
Q: What accuracy can I expect?
Handheld SLAM scanning typically achieves ±2–5mm accuracy depending on hardware. For higher precision requirements, tripod scanning may be more appropriate. Confirm accuracy requirements with your design team.
Q: How long does handheld 3D scanning take in Barnet?
On-site capture for a small property is typically a few hours. Processing and delivery take 1–2 weeks. Total: 1–2 weeks from instruction to final deliverables.
Q: What file formats do I get?
Standard formats include E57, RCP, LAS for point clouds, AutoCAD DWG for 2D drawings, and Revit RVT for BIM models. Additional formats (OBJ, STL, SketchUp) available on request.
Q: Do I need point cloud data or a BIM model?
For planning and design work, a point cloud is often sufficient for reference. For detailed design, coordination, and construction documentation, a Revit BIM model at your required LOD is the standard output. Discuss your deliverable needs with your scanning provider.
