From the beginning, our efforts have been carried by values such as team spirit​​, knowledge sharing, responsibility, innovation in order to give our employees the means of an harmonious development and to our customers the guarantee of a service. These efforts, it is our historical success and continued growth in four years of existence that are the most striking illustration.

INEXIA’s uniqueness lies in the fact that it is an engineering company capable of designing all types of transport infrastructure, with a specialized knowledge of railways derived from the SNCF. It is thus able to participate in the design stages, then assist companies during construction, carry out tests, and lastly maintain the railway infrastructure when in use.

This combination of skills is particularly suited to the public-private partnership contracts entered into for many high-speed lines meeting the development needs of infrastructure markets, the contracting forms of which are becoming more and more varied, leading to increasing demands for integrating these various types of expertise.

INEXIA is thus involved in all the French high speed line projects and our development has accelerated even more in urban transport, as we are now project managers for eight tramway lines.

Our ambition should extend considerably more to the international sphere, within the framework of the INEXIA integration into the SYSTRA engineering group, which is already very active internationally.

INEXIA future is made of challenging contracts, exciting projects and technical challenges. It is also made of new experiences. We owe it to the men and women of INEXIA and to our clients that trust on us.
