School Centre - 3D scanning, architectural plans & modelling

As part of the renovation plan for the commune of Vouvry (Valais), we were commissioned to carry out an external survey of the building.

Our services included 3D scanning of the building, including a drone survey of the roof and a survey of the interior stairwells to enable the local authority's building department to incorporate the interior floor plans previously surveyed into our plans.

The complete file includes a set of full architectural plans with sections, floor plans, façade plans and perspectives in PDF format.

A file in PLA format (archive folder for Archicad) and a file in IFC format for other 3D drawing software such as REVIT, Autocad or Revit.

Optimum precision thanks to 3D scanning

Le 3D survey of the Vouvry school centre is a perfect illustration of the precision offered by laser scanning. Every facade, roof and architectural element has been captured in minute detail, enabling faithful modelling of the existing structure. This method considerably reduces measurement errors and facilitates coordination between the various parties involved in the project. For the local authority, this guarantees a reliable and complete file that can be used directly in architectural software.

Integrating data into BIM software

By providing PLA and IFC files, 3D Scan Bat makes it possible to full compatibility with Archicad, Revit and Autocad. This interoperability makes it easier for architects, engineers and local authorities to work together. Each stakeholder can use the model according to their needs: design, renovation, volume management or surface area control. Thanks to this BIM integration, the school centre renovation project benefits from a robust technical base, ready for efficient planning and optimal data management.

Drone survey for a complete view

The roof of the school centre was surveyed using a drone equipped for photogrammetric and 3D capture. This technology makes it possible to collect precise data in areas that are difficult to access. Combined with terrestrial laser scanning, it provides a global and exhaustive vision of the building. This dual approach guarantees reliable documentation, which is essential for anticipating the technical constraints associated with renovation. For the local authority, it saves time and provides greater security when planning the work.

Valuable support for local authorities and architects

By combining PDF plans, 3D models and BIM formats, 3D Scan Bat provides local authorities and architects with practical tools that can be used immediately. The complete file delivered to Vouvry is not limited to a technical survey: it constitutes a real decision-making support for the renovation and management of the built heritage. This tailor-made approach demonstrates 3D Scan Bat's commitment to providing long-term support to local authorities and professionals in their development and construction projects.

Survey of stairwells: precision of circulation spaces

The stairwells at the school centre were accurately scanned to document the vertical circulation spaces. These measurements are used to check compliance with safety and accessibility standards.

The 3D capture of staircases includes the exact dimensions of steps, landings and railings. This data is essential for projects to bring internal passageways up to standard or renovate them. This provides the building department with comprehensive information for planning work.

Technical documentation for building permits

The complete file submitted to the local authority forms a solid basis for the administrative procedures. The sectional, façade and perspective plans make it easier to prepare the enquiry files.

La accurate 3D readings reduces the need to go back and forth with the cantonal authorities. The documents provided meet the technical requirements of the town planning and historic monuments departments. This rigour speeds up the process of obtaining the necessary permits for the renovation work.

3D modelling to simulate renovation scenarios

In addition to surveying the existing situation, the BIM files can be used to test different renovation options. Architects can simulate extensions, façade modifications or interior refurbishments.

This projection capability makes it easier for local authorities to make decisions. Elected representatives and technical departments can see the variants in concrete terms before approving them. The 3D model becomes an effective communication tool for presenting the project to stakeholders.

Dual ground and aerial approach for exhaustive coverage

The Vouvry school centre benefited from a combined methodology: ground laser scanning and drone survey. This complementarity ensures that all the building's surfaces are captured without any shadows.

Ground-based scanning documents facades, entrances and architectural details. The drone captures the roof and upper parts that are difficult to access. Assembling the two sets of data produces a complete, consistent 3D model that can be used for the entire renovation project.

Digital archiving for municipal asset management

Le PLA file is a permanent digital archive of the school centre in its state before renovation. This documentation will enable the commune to preserve a precise technical memory of the building.

This archiving makes it easier to carry out future maintenance or conversion work. The technical services have a reference that can be consulted at any time. This traceability strengthens the long-term management of the community's built heritage.

Intervention in Valais: proximity and responsiveness

From our base in Martigny, we can intervene rapidly throughout the canton of Valais. Our close proximity to Vouvry has enabled us to coordinate efficiently with the municipal services.

This local presence guarantees optimum responsiveness. We are familiar with the specific features of projects in the Valais and the requirements of public authorities. Our Swiss team carries out all services without subcontracting.

3D scanning of school and public buildings

Educational establishments require precise surveys for renovation, upgrading or extension projects. Our technology makes it possible to document the existing situation without disrupting the operation of the school.

Le 3D scanning adapts to the constraints of public buildings: accessibility, safety, working hours. We take readings quickly, minimising disruption to users and staff.

Conclusion

The Vouvry school centre project demonstrates the effectiveness of 3D scanning for renovation of public buildings in Valais. The combination of terrestrial laser surveying and drone scanning provides comprehensive documentation that can be used immediately.

Local authorities in the Valais can rely on our services for their projects to renovate, bring up to standard or extend public buildings. Based in Martigny, we work quickly throughout the canton.
