Building laser scanning

Many buildings have lost their design documents, or the drawings no longer match reality: walls have been removed, partitions added and services rerouted over the years. Knowing the true dimensions is essential for reconstruction, refurbishment, change of use or a property transaction, and laser scanning provides this information quickly and with high accuracy.

We scan the building outside and inside, including all floors, staircases, basement and roof. Interior and exterior scans are linked through door and window openings into a single point cloud, so wall thicknesses, floor levels and the relationship between storeys are determined precisely.

From the point cloud we prepare floor plans, sections and elevations in AutoCAD and a BIM model in Revit. Architects and structural engineers base their design on real geometry rather than estimates, which prevents surprises and extra costs during construction.

The survey is carried out without interrupting the use of the building. Measurement accuracy is 2–6 mm, and the drawings typically meet the requirements of 1:50 or 1:100 scale.

When you need it

• The design documents are missing or outdated
• Reconstruction, an added storey or a change of use is planned
• Accurate dimensions are needed for interior fit-out
• A BIM model of the building (Scan to BIM) is required
• Actual floor areas must be confirmed for sale or lease

What's included

• Interior scanning of all floors
• Exterior scanning of facades and roof
• Linking interior and exterior scans into one cloud
• Georeferencing the building
• Floor plans and sections
• Room area schedule
