At the request of a pension fund, we carried out a complete 3D survey of a block of flats in the canton of Bern. This work made it possible to obtain reliable plans, which were necessary for the establishment of social charges, the CECB energy study and the building permit application, although the file was prepared by a local architect.
⏱ 20-second summary
The building in question comprises several flats. The pension fund needed precise plans to organise the apartments. social costs between co-owners, establish a long-term maintenance planand enable CECB / CECB Plus energy study compliant with cantonal standards Expert CECBvd.ch. At the same time, a service provider carried out asbestos removal samples during the same visit, in order to group together the technical interventions.
Our ultra-precise surveys ensure that the architect has an accurate exact existing situation before preparing the permit application:
Millimetre-scale point cloud for reliable cross-sections, facades and site plans.
Deliverable formats (DWG, IFC, E57, PDF) for immediate use by the architect.
Exact basis for COS/CUSThese are the surfaces and volumes required for the survey.
BIM model LOG 200/300 ready to join the regulatory project.
Initial co-ordination - definition of requirements with the client (contingency fund).
On-site 3D scanning - interior, exterior, façade; simultaneously with asbestos removal sampling.
Data processing - formation of the point cloud, generation of deliverables.
Creation of CAD & BIM drawings - and forwarded to the local architect.
Multiple uses - permit application, ten-year maintenance plan, social security contributions, CECB energy study, public enquiry.
Reliable plans to share common charges fairly between tenants using a transparent tool.
The point cloud serves as a reliable basis for the CECB/CECB-Plus, which is essential in Vaud, particularly for renovations.
The architect uses our formats to complete the administrative procedure with the cantonal authorities.
Graphical support for establishing a 25-year planned maintenancein line with pension fund obligations
La immersive virtual tour offered in parallel with the 3D survey allows full visual recognition of each flat. Each visit is enhanced by a georeferenced photo fileThis makes it easier to carry out inspections, prepare reports for insurance companies and building owners, and coordinate work.
Logistical efficiency: 3D scanning and sampling carried out in a single visit, reducing costs and disruption.
Single database: several uses based on the same reference data.
Legal and energy reliability: multiple utilities for a single deliverable, validated by architects and CECB experts.
1. Why is a 3D survey essential for planning permission in Switzerland and the canton of Berne?
An ultra-precise 3D survey provides a reliable statement of the existing situation (millimetric point cloud, CAD plans, BIM model), which is essential for the local architect to prepare a permit file that complies with cantonal requirements (ACTIS-CAMAC). This deliverable enables precise regulatory calculations, reduces errors and facilitates the enquiry process.
2. How can 3D scanning and virtual visits help to manage social charges and the maintenance of a residential building?
Thanks to a virtual tour and a geo-referenced photo file of each flat, combined with reliable CAD plans, a pension fund can distribute social charges fairly, plan long-term maintenance and carry out energy studies (CECB) with accurate data, while grouping together technical interventions such as asbestos removal during the same visit.
How much does a 3D point cloud survey for a residential building cost?
The price for a complete 3D survey, including capture of the existing state and point cloud processing, generally starts at CHF 1 800depending on the size and complexity of the building. As an indication, for a medium to large building, the cost can be as high as CHF 3 000 à 5 000.
What about CAD plans, façades and sections?
Detailed CAD plans (floor plans, sections, façades) start from CHF 2 800. This price includes the production of usable files (DWG/PDF/IFC)
