vienna public transport - bus depot

concept
the large bus garage serves as a repair, service and storage hall for Vienna's liquid gas-powered buses, as well as an associated administration building. requirements relating to traffic, lighting, statics and operational organisation form a coherent structure, divided into workshop, storage hall and administration areas. the administrative building in the north of the site forms the connecting backbone between the two main volumes, the workshop and the parking halls. the compactness of the building guarantees efficient operational processes and minimises internal journeys and routes. an extended fire-fighting system allows the buses to be parked close together in the halls, minimising space and energy consumption.

workshops
the western part of the building houses the three workshops, which are divided into three areas: 1)  entrance hall with adjoining car wash in the west,
2) two-storey storage and workshop area, and
3) service hall
the workshops are lit via the east façade and skylights in the roof.

storage halls
the five storage halls form the south-eastern part of the overall complex. they are separated by sloping precast concrete walls, which are reinforced by columns and spanned by a steel truss. light enters the hall through skylights and is reflected along the sloping wall surfaces. canopies above the front access routes to the individual halls provide protection from the sun and weather.

administration building
the administration building is located in front of the workshops and storage halls to the north and spans the passageway between them on the upper floor.
ground floor
to achieve the necessary clearance, the ground floor and upper floor are raised by one metre. this creates a clear distinction between the ground floor and street level. rooms that do not require natural lighting are located on the partition wall to the storage hall. the internal access corridor is lit via the front surfaces and skylights from the atriums on the upper floor.  offices and recreation rooms are located on the north side to ensure optimal lighting without overheating in summer.
upper floor
the cloakrooms are located along the partition wall to the storage hall. access is via a central corridor, with lighting and natural ventilation provided by atriums. office, cultural and training rooms are located on the north side, lit by a continuous row of windows.

annexes, petrol station
energy annexes, liquid gas storage facilities and petrol stations are designed as individual buildings with the necessary safety distances to the overall facility.
