New construction of the cantonal administration building Neumatt, Burgdorf

The project
The Zeughaus PPP AG, newly founded by the competition winners Marti Generalunternehmung AG Bern and BAM Deutschland AG for this project, was commissioned by the canton to demolish the existing buildings and to construct buildings on the site for the cantonal police, the regional and juvenile court, the tax administration, and the central administration. Also the regional prison, the public prosecutor's office and the road inspectorate / civil engineering office with work yard were built. The entire development was certified Minergie- P- ECO. The administrative buildings were constructed as reinforced concrete skeleton structures. For the facades, elements in timber frame construction were placed in front of the supporting structure in concrete. The assignment for Timbatec was to develop suitable details and to verify the statics for the connections at floor transitions.

The construction
The main part of Timbatec's work on this project was the design. This included the issuance of plans with measurement of individual elements, control, threshold and facade plans based on the 3D model.

The challenge
A special angle had to be designed, which had to meet the following conditions: Fixing to concrete slab with at least 2 anchor bolts despite reinforcement Supporting the element of the upper floor. Support of the element of the lower floor Absorption of movements in the concrete (shrinkage, swelling) without loading the lower element. Dissipation of wind forces into the concrete slab.
