The new staff restaurant time out in the Cantonal Hospital Aarau was built in only eight months. The 3D planning and good project management enabled the fast construction time. ERNE as the general contractor and the planning team are in close cooperation with the client.

The Cantonal Hospital Aarau is planning a new building within the existing hospital area. It will replace the existing clinics. The construction activities with the clearing of the construction site began in 2019 and are largely completed by 2023. A temporary solution with an estimated operating time of 4-5 years will replace the existing staff restaurant. On November 30, the new restaurant named time out with 500 seats goes into operation.

The new restaurant had to be built quickly despite the limited space available. The price, easy dismantling and an inviting atmosphere for the hospital staff were important criteria. With these requirements in mind, the client examined variants: A building made of containers, a tent or a wooden structure were up for discussion. "A wooden system construction with a service life of 5 years proved to be the most economical solution", says Christoph Zehnder, Project Manager Architecture & Construction of the Cantonal Hospital Aarau.   


Fast construction time

In April the construction work started. At that time, some people doubted whether the new restaurant would really be ready by the end of November. "Even my fellow architects from the Architecture + Construction Department were not so sure whether the deadlines could be met," recalls Christoph Zehnder. The first wooden elements arrived on the construction site in mid-July. Only three weeks later, the entire timber construction was completely erected. As early as next week, the first lunches will be served behind the golden facade of OSB panels.

Perfect planning and good communication between the building industries made this fast construction time possible. Initially, the architectural plans were 2D. "We are glad that we switched to 3D planning. For the next project, I will demand 3D planning even earlier," says the client's representative.      


Planning with CadWork Team Module 

The planning team built a digital twin of the restaurant time out - even before the first piece of wood was processed. In this way, mistakes were detected during the planning phase and could be corrected without high cost consequences. The team module from CadWork was used for this digital twin. Several people work in linked 3D plans. "As soon as a specialist planner updates his model, the other participants receive a message. They, in turn, update their models to the latest state of the art," explains Urs Flükiger, divisional manager for plant layout at Timbatec.The CadWork Team Canada around Laurent Decosterd developed the team module.  Time out is the proof of concept in Europe - the team functionality will flow into the BIM Manager in one of the next CadWork versions.

Timbatec was not only responsible for the plant layout of all timber components, but also for the engineering work and fire protection. With well thought-out details Timbatec made sure that the staff restaurant convinced with functionality.
