Specialized in real estate, Hedenia's activities are threefold: project development and assistance, delegated project management for customers who don't have the time to follow a project, and management of the Group's real estate assets. Hedenia keeps an inventory of all the Group's real estate assets and monitors all aspects of their development (prevention, maintenance, security, upkeep, etc.) to ensure that buildings and their installations are always operational. Hedenia works to prevent risks; preventive maintenance, for example, makes it possible to plan maintenance work so that curative maintenance is more a question of emergency interventions than a lack of foresight.
