Currently the preliminary building works in the courtyards have been almost completed in the project Postgasse and the attic conversion has started.

The existing building of Postgasse is revitalized by Denkmalneu Gruppe and will be called “PLH – Post lebendiges Haus” (living house). The object has various types of use from hotel to flats, offices and an extensive fitness centre. A central element of the building is Dominikanerhof with approx. 1200 m², which not only comprises a 5-storey subterranean garage but shall also serve as room for events later. For this purpose the courtyard will be additionally roofed by a convertible membrane roof as weather protection.

The erection of a subterranean central cooling system in Barbarahof by Vienna’s energy supplier Wien Energie is a great challenge. The system will be supplied by water from the Danube Channel and shall provide district cooling to several large-scale projects in Vienna‘s first district. Due to the noise and vibration-intensive cooling units, the whole courtyard was decoupled by Sylomer and the machines themselves were embedded on mass-spring systems. Apart from numerical models for the assessment of secondary noise, measurements on the building site are also used.

The BIM project was completely modelled in 3D. Some field tests were performed by means of HoloLens for early detection of collisions between the wooden truss to be preserved and the new steel elements.
