The construction sector is undergoing profound changes, driven by new energy performance challenges, new infrastructure uses and major digital innovations such as BIM (Building Information Modeling) and Smart Building. In this context, Mews Partners supports the actors of the sector in their economic, business and digital transformations.

Like PLM projects, we intervene on several axes of their digital transformation: defining new value offers to propose to their customers, defining data management processes, mastering continuity throughout the building life cycle, improving business processes and the efficiency of projects in Lean mode, leading the change in order to guarantee the adhesion and the implementation of new practices by the operational teams.
