Crossing the Aessebaach valley
As part of the construction of the Junglinster bypass, Félix Giorgetti built a viaduct of 444 metres long by 17 metres wide. A great technical challenge for our teams.
The Junglinster viaduct has 5 spans and accommodates three traffic lanes. It is a mixed bridge with 2 metal box girders supporting a concrete slab of variable thickness from 0.25 to 0.40m.
Each truss has a length of 74m, a height of 6.45m and a total weight of 240 tons, and was transported to the site by 4 « exceptional load » transports and assembled on the ground before being lifted on the reinforced concrete hollow stacks.
The central span box, with a length of 37m, a height of 1.90m to 2.45m and a total weight of 65 tons, was transported to site in one piece.
The framework was erected parallel to the structure, except for pier 4 which was placed with a 90° rotation. The piece completely assembled has a length of 93.5m and a weight of approximately 273 tons, put in place by a high-capacity crawler crane.
After installation and adjustment of the framework, the construction of the reinforced concrete deck began. To do this, our teams created a mobile formwork box which, which made it possible to build the deck in its full width of 17m, totaling 24 concreting phases. Another first for Giorgetti.

Runway rehabilitation of the Findel airport
The only runway at the Findel Airport has been completely rehabilitated. In order to maintain the airport activities, the work was carried out only at night.
Félix Giorgetti, in a consortium with Karp-Kneip Constructions, built for lux-Airport a new checkpoint as part of the rehabilitation work on the Findel runway.
Rangwee Tunnel II
Félix Giorgetti built a second tunnel alongside the existing Rangwee tunnel.
