The road to the future

Implenia strives to ensure that a building is understood the same way by all the partners and customers involved in the project. This inevitably results in the enjoyment experienced during the planning process becoming actively supported and concluded together as part of a collaborative partnership. In order to achieve increased adherence to costs and schedules, we believe Building Information Modeling (BIM) is an essential component in our efforts to achieve operational excellence.

This revolutionary step is an outstanding opportunity for the construction industry.
