The principal contractor

The new “MedUni Mariannengasse Campus” is being built by the Medical University of Vienna and Bundesimmobiliengesellschaft. Several research centres will move in. These institutions are detailed below.   

The Medical University of Vienna

Medical University of Vienna (MedUni Vienna) is one of the most traditional medical education and research facilities in Europe. With almost 8,000 students, it is currently the largest medical training centre in the German-speaking countries. With 6,000 employees, 30 departments and two clinical institutes, 12 medical theory centres and numerous highly specialised laboratories, it is also one of Europe’s leading research establishments in the biomedical sector.


With 2,060 properties, the BIG Group is one of the largest property owners in Austria. Its portfolio comprises around 7.1 million m2 of rentable floor space with a company value (fair value) of around €12 billion. It is divided into divisions for schools, universities and specialist properties. Office buildings and residential buildings are combined under its subsidiary company, ARE Austrian Real Estate GmbH. ARE’s portfolio includes 558 properties with around 1.7 million m2 of rentable floor space. Whereas BIG primarily concentrates on public institutions, the ARE offering is designed to appeal to the private rental market. 

As a developer, the BIG Group is an important economic player in Austria. Efficiency and architectural quality go hand-in-hand, as is constantly being demonstrated. Every project endeavours to satisfy the needs of its future users in terms of ecological, economic and sociocultural sustainability. The BIG Group has received many awards for its architectural commitment and has so far won seven development prizes.
