Survey of a winegrower's house in Lavaux: measurements, 3D modelling and architect's plans

Commissioned by the commune of Bourg-en-Lavaux, we carried out the scanning of this winegrower's house in Epesses (Vaud) in June 2022.

The complete scan of the building required more than 300 scanning positions, and was completed by a photogrammetric point cloud of the roof using a drone.

After post-processing of the point cloud, it was modelled by our technical office in LOG 300. You will find more information on the nomenclature and degrees of detail between LOG 200 - LOG 300 - LOG 400 as well as the differences between the LOD and the LOG on our page dedicated to the LOG. BIM.

The section plans are extracted from the model in DWG format. They are ready to be inserted into 2D drawing software. The degree of detail of these plans corresponds to a level of detail of 1/100th.

Depending on the specific requirements of each customer, we can include elements such as radiators or technical ventilation or electrical elements.

Kitchens and bathroom fittings such as WCs, baths and shower tubs are represented in all cases.

3D scanning for winegrowing heritage

The Épesses winegrowers' house is a typical example of Lavaux architectural heritage. To ensure its conservation and renovation, the 3D survey provides essential precision. Thanks to more than 300 scanning positions and the use of a drone for the roof, the entire building has been documented with centimetre accuracy. This approach not only preserves the historic identity of the site, but also enables us to prepare interventions that respect its authentic character and structural constraints.

From the point cloud to BIM modelling

Once collected, the data from the laser scanner and photogrammetry are transformed into a dense point cloud. At 3D Scan Bat, our technical office processes this information to generate a BIM model in LOG 300, giving architects and engineers a reliable representation of the winegrower's house. The model makes it possible to anticipate constraints, assess volumes and optimise each phase of the renovation or conversion project, while complying with industry standards.

Accurate, usable architectural plans

The plans extracted from the model, supplied in DWG format, can be easily integrated into the 2D and 3D drawing software. Their 1/100th scale detail means that you can work directly on a solid basis for the design or conversion of the building. Depending on the customer's requirements, we can integrate technical elements such as radiators, electrical equipment or ventilation systems. These plans, which are both precise and flexible, are an invaluable asset for architects and building owners.

Expertise dedicated to local authorities and architects

By working with the commune of Bourg-en-Lavaux, 3D Scan Bat is demonstrating its ability to provide effective support to local authorities in managing their assets. Our approach combines advanced technology, technical know-how and an understanding of local issues. Each project benefits from comprehensive documentation and tools tailored to the realities of architects and town planners. The Epesses winegrowers' house is a perfect illustration of our commitment to providing reliable, appropriate solutions for preserving and enhancing traditional Swiss buildings.
