N09.70 MP-260005 Bächgraben Bridge SOMA / Project Manager Construction - ID 12052
Freihandvergabe an
Diggelmann + Partner AG
chf 280'414.85Spitalackerstrasse 20A, 3013 Bern
Description
Despite continuous monitoring of the BÄCHGRABEN BRIDGE since 2008, the condition of the expansion joint (axis 15) deteriorated rapidly and unexpectedly in autumn 2025, with structural components detaching from the base. At the same time, a static recalculation revealed a surprising and significant structural deficit in the outer spans. There was an immediate risk to traffic safety due to parts potentially falling onto the roadway and a risk of collapse of the bridge deck. The contract includes urgent detailed inspection of Bächgraben bridge, replacement of the expansion joints and temporary shoring of the outer spans.
