These incidents have had a major impact on the quality of the supply along with significant media coverage, and resulted in equipment damage.
Faced with this problem, this customer decided to launch a national programme to increase the reliability and the safety of its structures, covering an area of 10,000 m²:
With these goals in mind, the company undertook studies to determine how to improve the reliability of one source substation. The project management consortium was made up of Assystem (Lead) and two other companies, one of which is a 3D scanning specialist.
Project management for the required modifications (civil engineering, structure, high/low voltage, HVAC, road & utility networks, fire safety systems) to the existing building, which remained operational during all project phases:
The client also conducted its own design work concerning the high voltage process (HVA/HVB).
