Heritage & Maintenance


Originally created to respond to the needs of social donors seeking to involve several state bodies simultaneously within an extremely short period of time, its offer gradually extended to private donors and institutions. For the past 20 years, the department has been consolidating its skills every day and making ERI a reference for maintaining the Tertiary Park. ERI acquired the Qualification in Subsection 3 (SS 3) in 2017 through the acquisition of a new structure. It makes it possible to be more effective in the face of increasingly frequent requests for asbestos-related work. This allows us to offer a complete solution to our customers who have only one contact to maintain and value their heritage.
