The foundation stone for the "triad" in Aarau: another step towards the hospital of the future

On the morning of 8 April 2022, the client, the total contractor and guests met on the construction site at the Kantonsspital Aarau AG (KSA) to lay the foundation stone for the new Dreiklang hospital building.

With this laying of the foundation stone, an important milestone has been reached in the work on the new building project, which is to be ready for operation in 2026. With the help of the wooden model presented to the builder during the ceremony, all participants were already able to get a good idea of the future new building.

Eight months have passed since the groundbreaking ceremony - the impressive dimensions of the new cantonal hospital in Aarau can already be seen very clearly from the excavation pit. The dimensions of the new cantonal hospital in Aarau are enormous and the figures overwhelming: 9,200 lorries with excavated material have left here, 66,000 m3 of concrete and 9,200 tonnes of reinforcing steel have been used. These figures can be collected so precisely not least because the entire shell construction was no longer realised with conventional plans, but paperlessly on the basis of digital BIM models for more than 400,000 shell construction components. Each component has associated information. This data is managed in a BIM model and projected directly onto the construction site using so-called total stations and laser technology.

"Exactly 135 years after the foundation of the Aarau Cantonal Hospital and its persistent development into the largest hospital in the canton of Aargau, the comprehensive new building and the act of laying the foundation stone are also intended as a commitment to the secure and bright future of the KSA. It is a very special and forward-looking project and will set new standards in hospital construction in the healthcare sector beyond the borders of the canton. We are proud to be leading the work as general contractor and to be able to contribute our expertise and experience to the success of the project," says Jens Vollmar, Head Division Buildings at Implenia. "We would like to thank the KSA for their trust and look forward to the joint project and further collaboration!"
