Implenia enlarges the Kornhaus in Zurich

Coop has hired Implenia to manage the building work required to increase the height of the Kornhaus from 40 to 118 meters

Dietlikon, 19 April 2013 – Grain has been milled on Zurich’s Sihlquai for 170 years. Swissmill currently processes around 30 percent of the cereal needed for food in Switzerland there. The Kornhaus, one of four Swissmill grain silos in Zurich, is now being made 80 metres taller so that the company can maintain its capacities following the closure of a silo in Basel. Coop, the building’s owner, has awarded the construction site management contract to Implenia. Because it is being carried out while the mill continues to operate, the project presents difficult technical and logistics challenges. A further complication is that there is very little space to work in: the Kornhaus is bounded by the Limmat river, a railway line and a very busy road. Work begins in May 2013 and will take about two years to complete.

Implenia will be able to use its skills in industrial building construction and foundation engineering on the project. Additional civil engineering work will be done by KIBAG, with which Switzerland's leading construction and construction services company is forming a consortium.
