Reception Society Activities Achievements News Contact Our values A corporate culture focused on the quality of services: Quality of services: Since 1995 LEI has undertaken more than 100,000 diagnostic missions, thus illustrating the rigor of our procedures, compliance with regulatory requirements in the areas concerned and the constant search for improvement of our services. In addition, our associated Quality and Environmental approach (ISO 9001 and ISO 14001) contributes to the efficiency of our services and the satisfaction of our customers. Responsiveness, proximity and respect for commitments: The permanent evolution of the normative and regulatory production in our fields of activity imposes on our Design Office, an old constant of its evolutions and to suggest as well as to systematically advise our customers of these new constraints and the resulting solutions. Meeting contractual requirements also remains a top priority for LEI. Loyalty, confidentiality and capital independence: The specific nature of our missions and the resulting legal, technical and financial constraints for our clients oblige us to fully and completely maintain confidentiality.
