350-platz underjordisch Garagen

The Kunstmuseum Underground Parking Garage is located in Basel's St. Alban-Graben area, surrounded by significant landmarks such as the Museum of Art and Antiquities and major branches of UBS and CS. The new facility spans four basement levels and accommodates 350 vehicles. The construction aims to minimize surface traffic disruption by employing the cover construction method.

Phasenweiser Bau zur Verkehrskontinuität

The construction process involved a phased approach to ensure continuous streetcar and road traffic. Initially, traffic was shifted to the north side while an overcut bored pile wall and top concrete slab were constructed on the south side. Later, activities were shifted to the north, allowing completion of the tram route, utility lines, and road construction on the south side. This method ensured minimal disruption while facilitating efficient construction.

Technische Herausforderungen gemeistert

The project featured several technical challenges, including bored pile work within tight spatial constraints and coordination with multiple utility operators. Construction was occasionally paused to accommodate archaeological research. Despite these hurdles, the project adhered to a tight schedule with several fixed intermediate dates, culminating in the completion and handover in October 2021.

Umfangreiche Ausgrabung und Innenarbeiten

Within the scope of the services rendered, the project involved extensive excavation, demolition, underpinning, and the use of specialized techniques such as overcut bored pile walls and cover construction. The completion of interior work, including lighting and ventilation installation, marked the final phase before the garage became operational.

Baukosten 45 Millionen CHF

The construction volume totaled 45 million CHF, equivalent to 47.1 million USD. Credit Suisse Funds AG served as the building owner, with planning by Basler & Hoffman AG, Rapp Infra AG, and Stefan Meyer Architekten. The project represents a significant infrastructural enhancement, designed to accommodate growing urban mobility demands while preserving the city's historical and cultural essence.
