New Construction of the Y80 Multifunctional Laboratory Building, Zurich

The project
The University of Zurich’s multifunctional Y80 laboratory building on the Irchel Campus was completed between 2021 and 2024 and offers approximately 2,450 m² of fully equipped laboratory, surgical, and research space. It brings together several institutes and strengthens interdisciplinary research. The building features a modular design: while the base floors are constructed using solid masonry, the upper floors 1–3 were designed as timber-frame structures. This hybrid construction allows for flexible floor plans, a reduced construction time, and resource-efficient use of materials, all while meeting the high technical requirements of a laboratory building.

The construction method
Load-bearing beech beams and a precise truss system enable large-volume structures with few columns. Prefabricated timber structural elements for walls and box-girder ribbed ceilings (spans up to 7.2 m) were used. Columns and joists made of spruce glulam and construction-grade beech complement the system. Approximately 60% of the ceiling elements were manufactured with a raised profile.

The challenge
The laboratory building is designed to meet the demanding requirements placed on it by day-to-day research activities. The heavy X-ray machines generate high point loads. The large number of research instruments necessitates numerous wall openings. Transport logistics for 4.20-meter-high wall panels.
