Construction site of the week – Demolition of the former Postbank Carré in Munich

Since October 2023, the former Postbank Carré in Munich has been demolished by DA member company Ettengruber GmbH.

First of all, the building, which dates back to 1992, was gutted with 15 employees. In order to make the area accessible, the basement for the long front and the mobile crane and all upper floors for the compact excavator were supported with tree trunks and the existing building was protected with sand beds and enclosures.

Ground floor and basement to be retained

The special feature of the demolition project was that the ground floor and basement in the second building section, on which the equipment in the inner courtyard stood, were to be retained. Therefore, only the four upper floors were demolished with the long front and floor by floor with an 18 t compact excavator. The rubble was transported downwards floor by floor. In addition, elements were cut free using a concrete saw and lifted off directly using a mobile crane.

Logistical challenges

The only access road led through the demolition building, as there is a hotel on the other side. In order not to exceed the permissible ceiling load of the ceilings to be preserved, the demolition work had to be interrupted time and again so that the rubble could be removed. A total of 2,500 tons of rubble and 5,500 tons of concrete were produced. The material was processed into RC material at Ettengruber’s Pliening recycling plant.

Protection of pedestrians, traffic and neighboring hotel

The construction site was located in Munich’s city center right next to the main train station, next to residential buildings, stores, hotels and busy streets. Many pedestrians pass by here every day, so the construction site had to be completely scaffolded and suspended to protect traffic and passers-by. The directly adjacent hotel was also protected with noise protection scaffolding.

New design of the former Postbank Carré aims for LEED certification

The new “ELEMENTUM” project envisages the redesign of the Carré. Business premises and offices are to be created, as well as spaces for leisure activities. The project is aiming for LEED certification in all aspects, which means that the preservation of the existing building and recycling are top priorities.

Leadership in Energy and Environmental Design (LEED) is a green building classification system developed by the U.S. Green Building Council in 1998. It is a globally used sustainability certification and defines a series of standards for environmentally friendly, resource-conserving and sustainable construction.
