Bus garage and workshop by Pool Architects in Zurich / Function and dimensions – Architecture and Architects – News / Announcements / News
In the immediate vicinity of the Letzigrund stadium in the west of Zurich pool architects (Zurich) In 2020, a rational bus garage for the Zurich Transport Authority (VBZ) and a workshop with staff and office space for the Zurich Waste Management + Recycling (ERZ) will be completed. In 2015, the architectural office won the project competition organized by the City of Zurich. The submission? Was convincing both with its simple functional clarity and with the high-quality implementation in terms of urban planning and ecological aspects ?, as in the jury’s report on architectural reading.
With a width of 55 meters and a length of 70 meters, the structure completely extends the parcel and creates a uniform and distinctive opposite of the Letzigrund stadium in terms of urban planning. The building is divided into two areas: the ten-meter-high hall for the buses of the Zurich transport company and the ERZ-Werkhof, which is spread over three floors. In the basement there are work areas, washing and parking spaces for the vehicles, on the ground floor in front of the building there is a weather-protected Muldenstrasse and on the first floor ERZ employees have offices and lounges along a narrow atrium. The almost 20 meter high tower of the salt silo creates a powerful, sculptural symbol for the neighborhood.
The bus garage is free of columns thanks to large steel beams that span the hall. A shed roof is quickly used continuously for a photovoltaic system. The solid exterior walls made of concrete and the closed facades shield the neighborhood from operational noise. The raw in-situ concrete reinforces the monolithic shape of the building: a vertical battens temporarily the surrounding hall facade, a 45-degree rotated battens of the in-situ formwork optically reinforce the lines of force of the load-bearing wall elements. And a ring-shaped, small-scale structure emphasizes the round windows, skillfully interrupting the homogeneous structure of the outer skin. In contrast to the raw concrete, the staff and office rooms are furnished with warm, light wood.
The construction costs of the facility are given at just under 40 million francs. A significant part of these costs was devoured by the disposal of contaminated sites on the building site. In terms of sustainable construction and management, the large structure was predominantly made of recycled concrete. The roof water is collected in catch basins and used as process water. The PV system should cover most of the energy demand. (how)
