| Abstract: |
This paper reports on the key structure for the new light rail network in the area of Zurich-Airport – the Balsberg Viaduct. The project was published for total contractor submission in October 2005 based on a highly detailed preliminary project. The contract was awarded to a local joint venture team comprising two contractors (Marti AG / Stutz AG) and two civil engineering consultancies (Synaxis AG / Henauer Gugler AG). The paper comments on the several optimizations to the preliminary project made by the winning team. The challenges presented by the local soil conditions and the particularly restraining construction site conditions are also described. The Balsberg Viaduct is currently the major bridge project under construction in Switzerland. The viaduct will play a key role in bringing people closer to Zurich Airport – and thereby bringing Zurich and Swiss people closer to the world. |
