BIMmTool has changed how I carry out surveys by making them faster and more accurate. I no longer need to go to the building site; the vision of the point clouds is more than enough to visualize the building.
Philippe Stern runs Axiadessin, an independent drawing office in Bulle (FR), Switzerland. He is a specialist in converting building survey projects to high-quality BIM models. He has completed over 70 projects with BIMmTool and now recounts how BIMmTool helped him in a challenging historic heritage building project.
Could you, please, introduce yourself?
My company is called Axiadessin. It has been an independent drawing office for 30 years. I have done building surveys for years, with a manual system of taking measurements and redrawing in Archicad.
What is your usual workflow?
I cooperate with Mr. Antoine Estrugo, whose company, 3DScanBat, specializes in digital building surveying using photogrammetry and lasergrammetry. Axiadessin’s main profile is the recovery of point clouds for converting them into a BIM model on Archicad with the help of BIMmTool.
What devices do you use for capturing the point cloud?
We work with Leica and Matterport scanners.
What is the scope of your projects?
Most of our assignments comprise the supply of the BIM model (or also DWG) to our customers so that they have the “existing state” of the building requested. Given the development of the requests, we stop at this stage and deliver the results to an architectural office that carries out further project or building permit applications.
What is the contribution of BIMmTool in this process?
I discovered BIMmTool in 2021. The software has changed how I carry out surveys by making them faster and more accurate. I no longer need to go to the building site; the vision of the point clouds is more than enough to visualize the building.
To date, I have completed more than 70 objects with BIMmTool. I brought you a couple of examples, for inspiration:
Would you highlight a particular project where BIMmTool played a key role?
With pleasure!
The most complex and remarkable project was the recently completed “Pension Bienvenue à Lausanne“.
For an architect’s office in Lausanne, we carried out the 3D survey of this Hausmanian building by laser scan. We delivered a BIM model within the framework of the renovation of the building.
We completed the interior and exterior model in LOD 300.
The primary difficulty of the project is modeling the facades and roof because it is a protected building. It was necessary to reproduce each component as precisely as possible. The architectural office that will manage the rest of the project must comply with the fire concept and improve the global thermal envelope.
We had to pay particular attention to details, such as the entrance door, the corner chains, the corbels, the pilasters, and the rounded dome.
We took measurements with the laser scanner: it required 500 scanning stations.
🤓 We scanned the upper exterior floors with the help of a pole that allowed us to capture the exterior from the interior.
How did the project perform?
The estimated budget of the project was approx 15,000 EUR. Due to the difficulty, we delivered the project with a 3-4 day delay to plan.
How satisfied was the client?
The client was delighted and surprised by the quality of the model!
