The architecture, engineering and construction (AEC) industry and all related activities as building operation or maintenance are undergoing profound changes, driven by new energy performance challenges, new uses of infrastructure and major digital innovations such as BIM (Building Information Modeling) or Smart Building. In this context, Mews Partners accompanies players in the sector in their economic, business and digital transformations.

As with PLM projects, we are involved in several areas of their digital transformation: defining new value offers to provide to their customers, optimizing data management processes, managing continuity throughout the building lifecycle, improving business processes and the efficiency of Lean projects, driving change to ensure that operational teams embrace and implement the new practices.

Capitalize on BIM to accelerate the digital transformation of your processes and gain competitive advantage

BIM and the digital twin have been the driving force behind the digital transformation of construction, real estate development or operating companies. Their potential has been proven, and companies must now embed their applications in their business practices to make them a genuine lever of competitivity. Our expertise in technical data management throughout the life cycle of a building, coupled with our expertise in Transformation and Change Management, enables us to accompany our customers in order to help Operational and Management teams to optimize their business processes.

Bring value to your customers by implementing Lean right from the bid and definition phases

The sector is facing strong pressure on costs, deadlines and quality of their services in a multi-stakeholder environment. To meet these challenges, we help manufacturers deploy Lean methods from the upstream phases of the bid and definition phases, in order to control project management, streamline collaboration and optimize business processes by focusing on customer added value.
