1. Background to the project
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 in accordance with cantonal standards. At the same time, a service provider carried out asbestos removal samples during the same visit, in order to group together the technical interventions.
2. The benefits of 3D surveying for building permits
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.
This millimetre precision is particularly valuable when it comes to renovations or major transformationswhere every centimetre can influence the technical or regulatory feasibility of a project. Our 3D surveys guarantee compatibility with BIM and CAD software This facilitates communication between all those involved. Whether it's to check gauges, optimise buildable volumes or anticipate energy constraints, our method eliminates approximations and ensures that everything runs smoothly from the design phase through to administrative approval.
3. Stages in the process
- 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.
4. Use of deliverables
a. Social security contributions & pension fund
Reliable plans to share common charges fairly between tenants using a transparent tool.
b. Energy study / CECB
The point cloud serves as a reliable basis for the CECB/CECB-Plus, which is essential in Vaud, particularly for renovations.
c. Request for planning permission
The architect uses our formats to complete the administrative procedure with the cantonal authorities.
d. Maintenance plan
Graphical support for establishing a 25-year planned maintenancein line with pension fund obligations
5. Compatibility and use of data
Our deliverables are supplied in various standard formats (DWG, IFC, E57, PDF) to adapt to the specific needs of each project player. Architects can integrate our files directly into their BIM models, while engineers and technicians can use them for structural or thermal calculations. The data can also be imported into property management software to track the development of a property. This universal compatibility avoids time-consuming reconversions and ensures that the information collected remains usable for many years.
6. Virtual tour & documentation
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.
The virtual tours and geo-referenced photo files that we supply are also very useful in the event of disputes or claims. Dated and contextualised images can be used to prove the initial condition of a property and facilitate insurance cover. For asset managers, these documents serve as a reliable reference when planning works or monitoring interventions. This added documentary value goes far beyond the simple building permit, and provides a genuine management tool for long-term maintenance.
7. Advantages of this grouped approach
- 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.
8. Safety and regulatory compliance
In addition to technical precision, our process scrupulously complies with the cantonal and federal standards in force. Each 3D survey is carried out taking into account data protection requirementsThis compliance is a guarantee of peace of mind for our customers. This compliance means peace of mind for our customers, who know that their documents will be accepted unreservedly by the relevant authorities. Our work is covered by professional insurance, guaranteeing total protection in the event of a dispute or challenge.
