About us

The Haller Wasser compagny was born from the fusion of the complementary experiences of two official surveying and engineering offices, Christian Haller SA and J.-C. Wasser SA.

Our longevity has been built, year after year, thanks to the relationships of trust and loyalty that we maintain with our partners and customers.

The development of our office is part of a process of research and development in new technologies related to the territory, the act of building and mobility. We place listening at the heart of our service.

We have expanded in the state of Geneva and internationally, taking significant stakes in companies specialising in 3D and new technologies.
