The jobs at ISS are as varied as Switzerland itself. Some employees work partly underground, whilst others work at lofty heights. In this photo gallery, we take a look at some workplaces with breathtaking views – views that, for some, are simply part of their everyday routine.
Bolligen, Bern, Swisscom
Bantiger Transmission Tower
Height: 941 m above sea level
Tower height: 196 meters
Services: Maintenance cleaning
Interesting fact: The Bantiger transmission tower can be rented for private events.
Michael Häni, building manager (with ISS for 6 years)
“I’m responsible for various buildings. On Wednesdays, it’s always the Bantiger’s turn. I always look forward to it. Here, I get some fresh air and can take my mind off things. Another great thing is that I can watch the city of Bern change.”

Zurich ZH
Vulcano
Height: 402 m above sea level
Tower height: 80 meters
Services: Specialized and exterior cleaning, building management, building systems maintenance
Interesting fact: The facades of the three Vulcano Towers are cleaned twice a year. Ideally, Joel Moreira and his team need two months to complete the major cleaning, including the blinds. If only the windows are being cleaned, the job takes about five weeks.
“I love heights. They fascinate me and get my adrenaline pumping - even after 14 years as a specialist cleaner. Other people get their thrill from sports - I just go to work. I wouldn’t want to do anything else. This job gives me so much.”

Heimenschwand, Bern
Tertianum Schibistei
Elevation: 1 ,006 m above sea level
Services: Routine cleaning
Interesting fact: The Tertianum Schibistei residential and care center has a small on-site petting zoo with chickens and goats. This helps residents with dementia.
Annemarie Schlüchter, cleaning staff member (with ISS for 8 years)
“I grew up in this region and have known the guests since my school days. For me, Tertianum Schibistei is home. I feel at ease here surrounded by nature, and it helps me cope with difficult times. I’m very happy here.”
Geneva GE
Lancy-Pont-Rouge
Elevation: 380 m above sea level
Tower height: 60 meters
Services: Building systems maintenance, routine cleaning, property management
Interesting fact: We had to develop a unique safety concept here because trains carrying chlorine run very close by. Chlorine is toxic and can be deadly. Our concept protects the employees at Lancy-Pont-Rouge.
Cédric Erb, Technician/Site Manager (with ISS for 3 years)
“The height has never bothered me. On the contrary, I love it. The view is excellent, and I can watch the hustle and bustle of the city without losing sight of the Geneva Fountain. The building is a technical masterpiece and requires a great deal of expertise. Every day is an adventure, and no two days are alike.”
