Established in 1990 to provide environmental, safety and airport services, BTEE now has 30 staff at our locations in Switzerland and Belgium.

Over the last 25 years the company has established a solid reputation which has enabled us to export our know-how abroad to make us internationally recognised.

BTEE is made up of professionals from a wide range of backgrounds such as engineers, biologists, ornithologists, hydro-geologists, airport experts, occupational health and safety specialists and AEAI fire protection specialists. We also have a network of recognised partners for some very specific studies.

This depth of skills means that BTEE SA can offer our clients tailor made services that meet their needs and carry out high level multi-disciplinary studies.

Skilled project management, quality documentation and favoured contact with our clients – these are some of the strengths which enable us to be a leading point of reference in our areas of expertise.
