Digital transformation in the housing industry - An interview with Dr. Henri Lüdeke
Voxelgrid supported WBV Coswig in the digitization of its building stock. In this interview, Dr. Henri Lüdeke, Managing Director of WBV Coswig, talks about the challenges, solutions and successes achieved.

Initial situation and challenges
Voxelgrid: Dr. Lüdeke, can you give us an insight into WBV Coswig and your role as Managing Director?
Dr. Henri Lüdeke: WBV Coswig manages around 2,200 municipal residential and commercial units. Most of our buildings date back to the 1990s and 2000s and are now facing new waves of maintenance. A key challenge was the analog documentation: a huge paper archive with old, yellowed building plans made it difficult to determine quantities and measurements efficiently. The analog database simply no longer matched the digital working environment of our specialist planners and architects.
Voxelgrid: What specific challenges did you face with the “as-built documentation”?
Dr. Henri Lüdeke: The graphic representation of the actual built situation was not always complete or correct to scale. Over the years, a lot has been renovated, converted and changed. Yellowed DIN A0 drawings that were copied hundreds of times meant that important details were often no longer reliably recognizable.
Voxelgrid: Why was it so important for you to solve this problem?
Dr. Henri Lüdeke: On the one hand, we wanted to work more efficiently and prepare tenders more quickly. On the other hand, it was a question of motivation: well-trained employees should not have to spend hours in the basement copying and searching. We needed a digital solution to record buildings precisely and in a future-proof way.
The solution with Voxelgrid
Voxelgrid: Why did you choose Voxelgrid?
Dr. Henri Lüdeke: We already had experience with other providers who specialized in laser scanning. But Voxelgrid offered us much more: in addition to the scanning technology, we were impressed by their expertise in building physics, software development and in-house hardware development. I was particularly impressed by the use of photogrammetry, hyperspectral cameras and artificial intelligence for building assessment.
Voxelgrid: What specific technologies were used?
Dr. Henri Lüdeke:First, our building stock was recorded using the Voxelgrid Lidar scanner. This was supplemented by drone images for the façade and roof areas as well as photogrammetry to obtain realistic color models. Another important aspect was the AI-supported analysis, which was able to provide us with direct quantity data for tenders - from façade areas to gutters and paths.
