BIM, the first step in the digital transformation of the Saint-Brieuc Armor urban district

The Saint-Brieuc Armor urban district authority, committed to the digital transformation, commissioned the teams at SUEZ Consulting to incorporate BIM methods (Building Information Model / Modeling / Management) into the construction of a new drinking water plant. The goal is to develop new skills in order to set up 3.0 projects, carry out an organisational transformation and contribute to turning the Breton urban centre into a smart city.
The mission

Designing and developing a new drinking water plant

The increasing age of the Saint-Barthélemy plant and changes in regulatory standards led the local authority to plan the construction of a new plant with a capacity of 2,000 m3/h at the Croix-Cholin site in Ploufragan.

The existing drinking water plant has been extended and upgraded several times since it was first built. The raw water from the Gouët reservoir contains significant quantities of organic matter and various undesirable substances.
This is why the Saint-Brieuc Armor local authority commissioned the consortium of SAFEGE and Atelier Château to carry out project management, from preliminary studies to assistance with acceptance, to be delivered in 2024.

Incorporating BIM into existing processes to support the transformation towards the smart city

Pioneers in hydraulic infrastructure modeling since 2011, the teams at SUEZ Consulting incorporated the BIM method into the design phase for this project:

  • Design modeling
  • Design review
  • Producing 2D deliverables
  • Classification (coding)
  • 3D coordination
  • Consolidating the digital model

To ensure all the stakeholders could access full details of the project, the 2D deliverables were produced from construction trade-specific models and accompanied with immersive reality solutions. As a decision-making tool, this enabled the final version of the project to be visualised as accurately as possible.
Adopting these tools led to an increased mutual understanding of the challenges, and a real boost to the teams’ skills thanks to support at every stage of the project.

With data modeling and the transition to digital models, the work becomes a collaboration between all the construction trades and requires excellent coordination to manage these 3.0 projects
