The new office building for Roche, the healthcare company, will set new
benchmarks in terms of height: it will soar 178 metres in the air. “Building 1”
will be the workplace for 2000 employees spread across 41 floors. A top floor
cafeteria, 170 metres up, offers breathtaking views of the city of Basel.
“Building 1” reflects the Roche tradition in building architecture.
offices will be ready for occupation in 2015, with construction having started
in March 2012. The purely Marti consortium, comprising the sister companies in
Basel and Zurich, is responsible for the shell construction of what will be the
highest building in Switzerland when it is completed. The new construction will
be carried out in accordance with the Minergie standard.
principle is similar to that used for the Prime Tower in Zurich which was also
constructed by the firm of Marti. A 2.50 metre thick base plate, built on 143
foundation piles will bear the building load. Because of the height of the
construction a self-climbing tower crane will be used. Because of the
considerable horizontal forces created by the operation of the crane and the
wind loads, the crane will be anchored to the outside of the tower using spans.
A protective shield fitted to the existing concrete floors will be used instead
of scaffolding. It will provide exactly the same level of protection for the
construction personnel as a conventional scaffolding system which is unsuitable
for a building of this height.
In March 2012 the project team of the
Marti consortium moved into the site offices and began work. The team brings
with it the experience gained in the construction of Zurich’s Prime
