ABOUT

As part of the renewal of the DSP, we assisted the SMPRB in conducting an inventory of the TADEN UVE by producing 2D plans, 3D models, and virtual visits. Discover the benefits of this innovative approach.

SMPRB - 3D scanning and modeling of an EV At the renewal of DSP

Context and needs

The SMPRB (Syndicat Mixte de Valorization de Décretes des Pays de Rance et de la Baie), owner of the Taden plant, called on us to carry out a detailed inventory of the site as part of the renewal of its DSP. We have thus produced a “digital double” in several formats (2D plans, 3D models, virtual tour) in order to provide a complete vision of the site. During this type of renewal, a consultation is launched to select the future manager. A thorough knowledge of the installation allows candidates to build solid files and to better plan for the future management of the site.

The challenges

The SMPRB wanted to offer respondents a comprehensive view of the site. The waste recovery center was therefore scanned in 3D to freeze the condition of the building. The objective was to produce, from a single survey, a 3D model, a virtual tour and up-to-date 2D plans for the candidates. We were therefore asked for this operation, integrating numerous gateways and high-temperature areas.

The enacted solution

Fast & comprehensive 3D survey

A survey protocol with static, dynamic, and drone scanners for comprehensive data capture.

A rich capture

Joint acquisition of a 3D point cloud and panoramic images for greater accuracy.

Complementary deliverables

3D model, 2D plans and virtual tour, providing an overall vision of the site.

Enhanced consultation

Thanks to deliverables that enable precise projection into the UVE’s operation.

“This operation was a success as part of the renewal of the DSP. We are already imagining new uses around the model, concerning maintenance and monitoring the evolution of the site in operation.”

Transfer referent

The NavVis VLX scanner was used to cover all large areas of the building, where its use posed no technical constraints. These areas included spaces with relatively low ceiling heights, as well as environments that were not very repetitive and stable, without the risk of SLAM drifting or crashing, ensuring fast and efficient scanning. In addition, a static scanner was used to identify more complex, technical or cramped spaces. This static device made it possible to accurately capture areas requiring a higher level of detail, especially in narrow spaces or with specific equipment. The combination of the two methods ensured an exhaustive and accurate coverage of all surfaces, thus offering a reliable database for all future interventions.

The results achieved

Based on the 3D survey, a complete and accurate point cloud representing the building as it is was assembled. This point cloud is used as a basis for producing a faithful 3D digital model and detailed 2D plans, including sections and elevations, capturing each architectural and structural element.

Thanks to this method, we were able to document the current state of the building with great precision, allowing for an exhaustive vision that facilitates planning, management and projection in future projects for the renovation and optimization of the site.

SMPRB - 3D scan and modeling of a UVE at the renewal of DSP

As part of a renewal of DSP, we collaborated with the UVE of Taden to make an inventory of the site and enrich their consultation.
