Since the production of deliverables is shared across uses for all actors in the project, the potential return on investment is increased tenfold! Beyond this clearly identified time savings, from the inspection of the site to the analysis and estimation of the damage, other benefits are significant. In particular, we can mention the security gains induced by virtual access to buildings, or the reliability of studies.
ABOUT
In this case study of a housing disaster in Louhans, explore how a 3D survey of the building enabled stakeholders to more accurately assess the damage, and to remotely inspect the site throughout the project.

Post-disaster 3D scan: the complete case study of the Louhans fire
Context and needs
Following a major disaster on buildings hosting housing units in Louhans, we were contacted by Stelliant, more particularly by the group's insurance expert in charge of the project, in order to provide solutions adapted to the complexity of the disaster site and the associated technical constraints. Indeed, the site, composed of several interlocking buildings, resting on top of each other with levels and half-levels, had a complex configuration. It was impossible to start the study project without a precise and detailed overview of the site, a prerequisite for ensuring the proper conduct of the work.
The challenges
A misdiagnosis could have launched the project on the wrong footing, thus compromising its success. This is why the 3D survey played an essential role in providing an accurate vision of the site. This key step made it possible to lay solid foundations, thus guaranteeing the smooth running of work, facilitating coordination between actors. An essential process to avoid any deviation and to ensure the smooth running of operations.
The enacted solution
01
Production of deliverables
Point cloud, 3D digital model, 2D plans, and photogrammetric rendering.
02
Digital access to the building
Allowing the building to be inspected remotely at any time and safely.
03
Technical deliverables
Allowing damage to be estimated and future renovation projects to be designed.
04
Product mission report
Incorporating visuals of deliverables illustrating the context and damage of the disaster.
“3D scanning is an initial investment, which opens up to multiple uses (detecting the causes of claims, estimating damage, securing visits) to save a significant amount of time, particularly on complicated cases.”
Mr. ROUSSELOT
Insurance expert
The Louhans project involved a complex collaboration between all actors, each playing an essential role in the restoration. On the one hand, insurance experts, policyholders and disaster victims worked together to establish an accurate assessment of the damage. On the other hand, the technical studies called on the structural design office, the diagnosers and the architects. These actors were able to collaborate effectively thanks to common references such as 2D plans, a 3D model, virtual visits and photogrammetric renderings. These tools facilitated a coordinated and secure approach to carry out inspections and studies successfully, ensuring rapid and accurate decision-making. They also optimized deadlines, reduced the risk of errors, while ensuring the quality of restoration work and the safety of interventions on site.
