Initiate renovation projects on the basis of reliable plans

As part of its dynamic expansion in France, B&B HOTELS is preparing to reach the milestone of 400 hotels, largely thanks to the acquisition of existing establishments. However, the brand faced a major challenge: the documentation for these buildings was often outdated, illegible, or non-existent.

For these multiple renovation projects, the absence of reliable 2D plans made planning complex and risky. It is in this context that B&B HOTELS asked My Digital Buildings. Our mission was to provide an accurate database for the renovation of 14 hotels across the country, by deploying two types of scanners and by identifying more than 25,000 m² of built area in record time.

This first collaboration, initiated on 14 establishments, has since been extended to the scale of the brand, laying the foundations of a sustainable strategic partnership.

To meet the requirements of B&B HOTELS, we have implemented a streamlined approach, relying on our network of agencies in France to send statements in an optimized time frame, then relying on the point clouds identified to produce 2D plan files.

This “scan to plan” process, which consists of drawing precise 2D plans from the point cloud of each building, guarantees centimeter precision important for B&B Hôtels, which in particular had fairly fine stakes around the layout of spaces.

To ensure rapid and comprehensive surveys, My Digital Buildings has developed an innovative protocol. Each mission combined the simultaneous use of two state-of-the-art equipment:

• The NavVis VLX mobile scanner : allowing a rapid survey of open areas such as halls, rooms and corridors, with an impressive rate of 300 m² per hour.
• The Leica RTC360 static scanner : used to capture more complex or external areas with extreme precision, such as facades, stairwells, technical boiler rooms, roofs, and land plots.

Each of these scanners collects point clouds, which are then cleaned and assembled to form a global point cloud of the building, the future layer for drawing 2D plans.

Standardized plans adapted to the uses of B&B Hotels

As part of this collaboration, our mission was to produce Level and facade plans for each hotel. Far from being simple drawings, these deliverables were designed to meet the specific needs of B&B HOTELS.

In particular, we have set up:

• Standardization of plans : To ensure perfect readability and consistency across all sites, we structured the plans according to a common framework, co-defined with B&B HOTELS. This approach allowed for more fluid and efficient use of documents.
• Optimized production : Our production rate has been specifically adjusted to support the company in its strong growth and the pace of its acquisitions.
• The integration of hotel specificities : We have integrated crucial elements for the management of the works, such as the numbering of the rooms and the precise design of the PMR equipment and furniture.

Focus on areas and elements related to the mobility of PMR

The renovation of B&B HOTELS hotels has been designed with particular attention to accessibility for People with Reduced Mobility (PMR). As such, My Digital Buildings has ensured a representation of up to the centimeter of essential elements such as sanitary blocks, furniture, and equipment dedicated to the accessibility of PMR. In particular, the dimensions of these elements have been added to the plans.

This precision was crucial to identify with certainty the travel areas adapted to PMR, while avoiding any margin of error.

Reliability guaranteed by rigorous quality control

To ensure the completeness and precision of our deliverables, our production process is based on a rigorous approach. We have combined two essential digital tools: point cloud, which serves as a 3D footprint of the building, and a immersive virtual tour places.

Using these supports, we were able to draw 2D plans of a centimeter precision, ensuring perfect fidelity between reality and its representation. This reliability has been crucial, especially for areas that require particular attention, such as the design of spaces adapted for people with reduced mobility. By ensuring that the design was up to standard from the start, we not only optimized project planning for B&B HOTELS, but we also contributed to the creation of facilities that were more inclusive and accessible to all.

In parallel with this approach, a strict quality control grid co-designed with the customer has been defined, allowing us to validate each plan before delivery.

In addition to the 2D plans, My Digital Buildings offered B&B HOTELS a complementary deliverable that proved extremely useful in the renovation process: a virtual tour of each hotel identified. In particular, this support allowed the work management teams to:

• Take measurements of elements not represented on the plans using a coastline measurement feature integrated into the virtual tour.
• Reduce travel and allow teams to save time during the planning phase.
• Anticipate certain work topics prior to site visits, thus optimizing the time of the teams in the field.
• Contextualize exchanges with visual references.
• Facilitate work declarations by exploiting more comprehensive documentation.
