What Is the FJD Trion P1?
The FJD Trion P1 is a compact, handheld SLAM-based LiDAR scanner designed for fast, grab-and-go 3D reality capture across construction, property, and infrastructure environments.
It uses SLAM technology to build a real-time map as you walk through a space — no static tripod setup required. It captures 200,000 points per second, weighs just 1.1 kg, and delivers up to ±20mm relative accuracy at ranges up to 70m.
Full workflow: capture → post-process in Trion Model → deliver floor plans, BIM models, or stockpile volumes (scan-to-processing ratio approximately 3:1).
Key Specifications
| Spec | Value | | --- | --- | | Weight | ~1.1 kg | | Scan Range | 70m (80% reflectivity), 40m (10%) | | Accuracy | ±20mm relative, ~5cm absolute | | Point Rate | 200,000 pts/s | | LiDAR FOV | 360° × 59° | | Protection | IP55 rated | | Outputs | LAS, PCD, PTS, PLY point clouds; floor plans; BIM |
Construction and Surveying Use Cases
As a QS, you'd find it particularly useful for:
- As-built surveys — rapid interior/exterior capture for scan-to-BIM or scan-to-CAD
- Floor plans — automated 2D plans from 3D scans
- Stockpile volume calculations — fast measurement without manual taping
- Underground/confined spaces — tunnels, manholes, culverts where traditional methods are impractical
- Defect documentation — capture spatial evidence for NEC contract records or dispute resolution
UK Hire and Purchase
Purchase: New units from ~$5,999 USD (~£4,700) on the FJD Trion store. UK resellers may price slightly higher with VAT. Demo/refurbished units available.
Hire: SEP Geospatial is the main UK hire source, covering most of England and Wales via their own fleet delivery (within 2–3 hours of depots). Also ships nationally via UPS. Call 01695 667143 or submit an enquiry form.
Other options: Drone Services Solutions UK, Survey Tech UK, and local geospatial survey companies offering managed scan services (bring the scanner and process data for you).
When the P1 Beats Other Scanners
| Scenario | P1 Advantage | Choose Alternatives | | --- | --- | --- | | Confined/complex spaces | SLAM navigation; no line-of-sight needed | Static scanners where accuracy is critical | | Large open areas | Fast walk-through capture | Tripod scanners for georeferenced accuracy | | Underground/tunnels | Works without GNSS | Traditional surveying | | Quick progress scans | Fast mobilisation | When mm-level accuracy required |
Frequently Asked Questions
Q: How accurate is the FJD Trion P1?
±20mm relative accuracy — suitable for as-built documentation, volumetric calculations, and BIM clash detection. Not survey-grade (requires tripod scanners for ±1–2mm).
Q: Where can I hire a Trion P1 near me?
SEP Geospatial (sepltd.com, 01695 667143) covers most of England and Wales with 2–3 hour delivery from their depots. Also ships nationally.
Q: What does the Trion P1 cost to buy?
Approximately £4,700–£9,500 depending on reseller and new vs. refurbished. UK resellers typically quote from ~£9,500 ex VAT.
Q: What data does the Trion P1 produce?
Point cloud files in .las, .pcd, .pts, .ply formats — compatible with all major BIM/CAD software. Also produces automated floor plans and supports BIM workflows.
