Science Circle construction progresses ahead of schedule
Construction of the AO Foundation’s Science Circle, the centerpiece of the AO Campus on Clavadelerstrasse, is progressing rapidly and remains ahead of schedule, promising a new era for scientific research and innovation in Davos.
Initiated in April, the excavation for the Science Circle presented unique challenges due to the AO Foundation’s location on a former community waste disposal site. In a remarkable display of environmental responsibility, the AO recycled a staggering 6,500 cubic meters of household waste from the 1970s, including 3,800 cubic meters of contaminated special waste. Over 500 truckloads were required to remove the waste, which was accomplished without the need for financial support from local or cantonal authorities. The AO Foundation’s commitment to sustainable construction underscores its dedication to both its employees and the population of Davos.
Despite heavy rainfall in May and early June, the excavation and waste recycling were completed smoothly in June. The next phase—drilling the piles—was met with unforeseen difficulties caused by unstable, waterlogged soil. Heavy machinery risked sinking, prompting engineers to implement stabilization measures using geogrids and crushed concrete. This effective solution allowed drilling to commence by the end of June.
Piling work resumed after a brief summer break, and by the first week of September, all 224 piles, totaling 6,024 meters, had been successfully installed. Construction continued until mid-November, after which the site was protected for the winter. The basement is now complete, the ground floor is underway, and connections to the AO Center and storage area were finished prior to the winter break—marking the project as slightly ahead of schedule.
Work will recommence in April with the construction of the outer walls. The final building height is expected to be reached in summer 2026, with the building’s inauguration planned for summer 2027. The ring-shaped Science Circle will serve as the pulse of the AO’s research and innovation, featuring cutting-edge laboratories, offices for researchers, and an auditorium with up to 200 seats. The new building is central to the AO Campus vision, which seeks to provide modern, sustainable, and flexible workspaces for all AO employees.
Upon completion of the Science Circle, the existing AO Center will undergo a comprehensive renovation, anticipated to last one year, with reopening scheduled for late 2028.
The ongoing construction has not affected the routing of the surrounding cross-country ski runs. As soon as snow conditions permit, ski run number 14 toward Wildboden will be prepared as usual.
