LeopoldQuartier information exhibition and dialogue event

On 4 and 5 March, MA21 of the City of Vienna invited the residents of the LeopoldQuartier to the former premises of A1 at Obere Donaustraße 23-27. We are pleased that about 250 visitors accepted this invitation to inform themselves about the current project status. On two afternoons, experts from the fields of green and open space, transport planning, as well as representatives of the City of Vienna and the district, the area management and UBM Development Österreich GmbH were available to answer questions from all interested parties. The citizens' initiative BiLG (with its own information stand) was of course also represented. Prior to the start of the urban planning competition, all citizens were able to express their concerns once again, which was also taken advantage of in large numbers. In addition to the demands of the BiLG that have already been taken up, the results of this event will now be added to the call for proposals, so that nothing now stands in the way of the start of the process. Since the selection and qualitative development of the planners will take several months, we expect the results of the competition in the summer. Of course, we will continue to keep you up to date on our website and in the meantime we will be happy to answer your questions. We, UBM Development Österreich GmbH, would also like to take this opportunity to thank you again for coming and for your interest in our LeopoldQuartier.

Works on the roof of Obere Donaustraße 29

On the 29th and 30th of October, works will be carried out on the roof of the building in the Obere Donaustraße 29 by A1. The mobile phone antenna and recooler of the former tenant will be removed from the roof. The works will be carried out with a mobile crane and are planned within normal working hours. However, since the crane is a heavy-duty vehicle, it is only allowed to drive in public traffic areas between 0:00 and 5:00. The removal of the crane is scheduled for the night from Wednesday to Thursday between 0:00 and 4:00. We ask for your understanding in case of resulting inconvenience.
