The new staff restaurant time out at the Aarau Cantonal Hospital was built in just eight months. 3D planning and good project management made the fast construction time possible. The building owner is grateful to ERNE as the general contractor and to the planning team.
The Aarau Cantonal Hospital is planning to build a new a new building within the existing hospital site. It will replace the existing clinics. Construction activities with site clearance began in 2019 and will be largely completed by 2023. A provisional facility with an estimated operating time of of 4-5 years will replace the existing staff restaurant. On November 30, the the new restaurant named time out with 500 seats.
The new restaurant had to be built quickly space conditions, had to be built quickly. The price, easy demountability and an inviting an inviting atmosphere for hospital staff were important criteria. criteria. With these requirements in mind, the client examined variants: A structure made of containers, a tent or a wooden structure were up for discussion. "A timber system building with an operating life of 5 years turned out to be the most economical solution," says Christoph Zehnder, Project Manager Architecture & Construction of the Aarau Cantonal Hospital.

Faultless planning and good communication between the trades trades made this fast construction time possible. Initially, the architectural plans were 2D. "We are happy, we switched to 3D planning. On the next project, I will ask for 3D planning even sooner," says the Owner's Representative.
