Reality Capture
Our own Swiss crew on site with terrestrial laser scanners and drones. Georeferenced, full coverage, and planned around the daily routine of an occupied building.

Swiss Scan-to-BIM · Capture and model, one team
From 3D Scan
to Accurate BIM Models
Digital building surveys, point clouds, and BIM models for design, renovation, and building documentation. Scancrew captures existing buildings using advanced 3D laser scanning technology and transforms the collected data into structured, design-ready BIM models.

Scan to BIM
Scan to BIM — turning an existing building into a digital asset.
Most existing buildings are documented by a plan set that stopped being true years ago. Walls moved, openings closed, services were rerouted — and each change left a note in a file rather than a correction on a drawing. In renovation and refurbishment work, that gap between the drawing and the building is where design errors, site rework and unbudgeted cost come from.
Scan to BIM closes it by measurement. We capture the building with 3D laser scanning, register the scans into a single point cloud, and model that cloud into a structured BIM model — so the geometry your project plans against is the geometry that is actually there.
The result is not a one-off deliverable. A checked model of the existing building carries forward: design today, coordination next quarter, area statements and facility data for as long as the building stands.

The Pipeline
One chain. No handoffs.
Capture, processing, modelling and quality control run inside one team. Brief us once and we hand back a model your project can build on — or start mid-chain and send us your existing point cloud.
Point Cloud
Scans are registered and validated, noise is cleaned, and the coordinate system is fixed. What leaves this stage is a dataset you can measure against.
- Registration
- Validation
- Noise cleaning
- E57 · RCP · RCS
BIM Production
Architectural and structural elements are modelled in Revit or Archicad, aligned directly to the point cloud, to the agreed LOD — not traced from exports.
- Revit
- Archicad
- LOD 200 · 300 · 350
- Cloud-aligned
QA/QC
Three reviews before release: the modeller verifies geometry against the scan, a Senior BIM Modeller runs the technical review, and the Team Lead performs final validation.
- Modeller self-check
- Senior technical review
- Team Lead validation
Delivery
The native model plus IFC for openBIM workflows, optional 2D drawings, and review snapshots with documentation.

What we do
Four services. One continuous chain.
Each service stands on its own and hands a finished, checked deliverable to the next. Nothing has to be re-measured between them.
Who it's for
Built for the people who have to trust it.
01 / 05
Architects
You need as-built plans that match the building before renovation design starts — not drawings from 1987 with pencilled corrections. We deliver geometry you can plan against.
02 / 05
BIM managers
You need a model that imports clean: correct element classification, sensible structure, nothing to rebuild. Our QA chain exists so your cleanup stage doesn't.
03 / 05
Surveyors
You capture, we model — or the reverse. Send point clouds in E57, RCP or RCS and get back structured models at stated tolerance, under your project's coordinate frame.
04 / 05
Construction companies
You need reliable existing conditions before pricing and sequencing work in an existing structure. ±20 mm as-builts take the guesswork out of the tender.
05 / 05
Property owners
A building you own should be documented as it stands: a durable digital record for renovation, leasing and facility management — independent of any single project.

FAQ
Technical questions, plain answers.
Standard tolerance is ±20 mm between model geometry and the point cloud. Tighter tolerances are possible for specific elements and are priced per project. Accuracy is verified during QA against the scan data — it is not an assumed figure.
