A team of experts


With in-house teams with a wide range of skills (architectural, technical, legal and financial), THEBAULT INGENIERIE is able to work alongside its clients in every phase of their project.

The solidity of a large group


THEBAULT Ingénierie was founded in 1982 and acquired by the IDEC GROUP in 2006. They are able to make the most of all the other resources within the group (investing, developing, designing and building) and take advantage of its financial solidity.

Our expertise in design, our proximity to customers allow us to link strong partnership relationships. It’s an unequaled strength the complexity of our projects. This strength allows us to perform on quality at all levels.
