Measured
building survey

We provide professional measured building surveys using FJD Trion X1 and T1 LiDAR scanners. We capture the as-built condition of the building quickly and with millimetre accuracy — interiors, facades, plant rooms and the surrounding terrain. You receive accurate point clouds, 2D drawings, 3D models and BIM data compatible with Revit, AutoCAD, Archicad and other CAD systems.

A digital record of your building. Complete and accurate.

A measured building survey documents the as-built condition of a structure in detail: its geometry, structural elements and components. Instead of measuring by hand with a tape, we use professional 3D laser scanning (LiDAR), so you get complete 3D documentation faster, more accurately and without missed details. It serves renovations, sales, heritage conservation, property management and design work.

Exterior survey

Complete capture of facades, roofs, terrain and surrounding features, georeferenced. Ideal for large buildings, heritage sites and industrial complexes.

Interior survey

Detailed scanning of rooms, corridors, plant rooms and attics. We capture the geometry of walls, ceilings, openings and services without manual measuring.

Point cloud

The output is a dense point cloud with colour information and precise coordinates. Compatible with Revit, AutoCAD, Archicad and other professional tools.

BIM model

A building information model (BIM) based on the scanned data. Every element carries both geometry and metadata for managing the building throughout its life cycle.

2D drawings

From the 3D data we derive scaled floor plans, sections and elevations at the required accuracy, in DWG or PDF format ready for design work.

Digital twin

A complete digital copy of the building for viewing, presentations, virtual tours, simulations or renovation planning without a site visit.

Two professional scanners cover every building

For building surveys we use FJD Trion LiDAR scanners — the handheld X1 with a 360° camera for interiors and facades, and the hybrid T1 for large sites, measuring details from a tripod with 4 mm accuracy. The two devices complement each other and guarantee a complete, accurate survey.

Combined approach
The right scanner
at the right moment

On most projects we use both scanners — the X1 walks through the building and captures interiors and facades in colour, while the T1 covers the surrounding site at the same time and measures from a tripod wherever the highest accuracy is needed. FJD Trion Scan collects the data in the field, FJD Trion Model merges it and exports to LAS, PLY, OBJ, DXF and other formats — all without external tools.

Five steps from the first meeting
to the finished model

We run the whole process to keep the burden on you to a minimum, from a free initial consultation to the handover of complete deliverables.

01

Consultation

We go through the purpose of the survey, the size of the building, the required accuracy and the output formats. You receive a no-obligation quote.

02

Scanning

The team arrives on site with the X1 and T1 scanners. A standard building typically takes 1 day, larger properties 2–3 days.

03

Data processing

We merge the scans into a point cloud in FJD Trion Model software and align it to the coordinate system.

04

Modelling

From the point cloud we derive 2D drawings, a 3D model or a BIM structure according to the agreed scope and LOD.

05

Handover

You receive a complete package of deliverables in the agreed formats, including documentation. Consultation included in the price.
