Blending past and present

At 29-31 Avenue de la Gare in Luxembourg-City, Félix Giorgetti is blending past and present.

A very technical project has taken place at the 29-31 Avenue de la Gare in Luxembourg City. A project where Félix Giorgetti has demolished existing buildings to make room for new mixed-use structures.

There was one constraint, however: the historic facades had to be preserved and restored. A mission that was carried out in collaboration with the architect of the National Sites and Monuments Service. This major demolition phase required securing all the neighbouring homes.

Technical and logistics challenges

For lot 29-31, the teams stabilised the 370m2 of facade and pinned the two adjoining gables over an area of 880m2. The existing buildings were demolished and 28 tie rods installed under the facade to be retained.

The project consists of two underground levels and seven above-ground levels. It includes 2,300m2 of offices and 876m2 of retail space. The structural work began in late September 2021 and is scheduled for completion by the third quarter of 2022.

Working in a very small environment, a technical and logistical challenge

This work is a real challenge for our teams who have to work in very restricted spaces and demonstrate exemplary capabilities in terms of logistics, as many factors make their progress more complicated: road and pedestrian traffic which cannot be interrupted, access to the site, the use of heavy-duty machinery, shift work scheduling, relations with local residents and noise pollution, among other things. Some work, such as casting concrete slabs, is carried out at night to make sure teams can proceed without blocking street traffic.
