The challenge also lies in the schedule, since the shell of the building must be completed by the end of 2024. That's just nine months after work began.

Reactivity and mobilisation

In March 2024, F&eacute;lix Giorgetti launched the construction of Losch's new headquarters in Kockelscheuer, all&eacute;e Louis Ackermann in the municipality of Roeser. Located alongside Cube 4T8 - Losch's innovation centre - the 9,772 m2 office building is designed to accommodate 300 people over three floors, with two levels of basement parking. The building has been designed with sustainability in mind, and will incorporate geothermal energy, a photovoltaic system and a rainwater recovery system.
Impeccable execution
What's special about this project? The majority of the building is made of architectural concrete, which means that the walls will be left exposed. The quality of the concrete and its execution must therefore be impeccable. Of the 7,253 m3 of concrete, 4,560 m3 will be made from visible concrete.

Losch Luxembourg, a company with a long history in the automotive sector, laid the foundation stone for its new head office this year. And the historic automotive company entrusted the structural work to Félix Giorgetti.

The walls are made of architectural concrete.

The construction of a hospital involves a number of technical features, including the use of baryta concrete (high density) for the so-called "critical" areas, which contain X-ray machines or sensitive products. The building's waterproofing has also been improved. The perimeter walls and floor slab are covered with a white tank. The reinforcement is reinforced to prevent cracking, and all critical points such as the joints where the concrete is poured are treated to ensure watertightness. A membrane that adheres to the concrete as it is poured is used for critical areas.
Delivery of the shell, external fittings and networks is scheduled for the end of 2027.

Technical features

Conception

Covering an area of 54,158 m2, the new building stretches between Val Fleuri and Rue Ferderspiel, on the site where the old maternity hospital once stood.
The building has nine storeys and three basement levels. It has 378 rooms, 478 beds, 18 operating theatres, 6 endoscopy rooms and two helipads.
The aim of the project is to bring together on a single site all the acute clinical activities hitherto split between CHL Centre and CHL Eich, as well as the Institut national de chirurgie cardiaque et de cardiologie interventionnelle (INCCI). It is also surrounded by the existing CHL, to which it will be linked by a footbridge, and the maternity unit, which opened in 2015.

A project under discussion since 2013, the long-awaited construction of the new CHL began in February 2024. The structural work on the country's largest hospital is being carried out by the joint venture of Félix Gioregetti, CBL, Galère Lux and Lux TP.

The project also includes visible concrete elements such as the central staircase, underground elements such as these columns and perimeter walls.

The new hospital should open in 2028.

Nestled between the exit of the Fort Neipperg car park and the platforms of Central Station, the rue du Chemin de Fer will play a very important role in the construction of the new CFL headquarters. It will indeed be the entry point to the site. The road is being widened in two stages, with the first part completed in July 2023. The work involved widening the road and creating an access ramp to allow machinery to reach the site several metres below. The second phase will take place at the end of 2026, when the building is handed over and the ramp becomes an access point for emergency services.
<h3>From 3.5 to 7 m wide</h3>
The challenge lies in the narrowness of the site, between the car park exit at the top and the station platforms at the bottom. To maintain one-way traffic, an impressive gantry crane was installed, with a 60 m long jib and a hook height of 36 m. Our teams demolished the stairs leading down to a platform, as well as part of the platform and the retaining wall. New foundations were laid to build a new retaining wall, making it possible to extend the road from 3.5 to 7 m in width. The new road rests on 6 m-high mews, beams, predales and slabs cast on site. It is bordered by prefabricated cornices. The asphalt was laid by our partner Julien Cajot.

As part of the construction of the new CFL headquarters, our teams widened the Rue du Chemin de Fer.

Preparatory work

The joint venture F&eacute;lix Giorgetti, CDCL and Poeckes was chosen by Chemins de fer luxembourgeois to build its new 24,000 m2 head office.
It was also awarded the contract to install the living quarters, as well as cleaning out the old building and stabilising its fa&ccedil;ades.
Completion of this major project is scheduled for 2026.

A large-scale project

A project with a very interesting architectural and environmental concept that echoes the values of our company. CFL opted for a partial demolition of the old building, which dates from the 1950s, while preserving elements typical of the architecture of the period, such as the main fa&ccedil;ades overlooking Place de la Gare, the central core, the entrance staircase and the mosaic mural in the entrance hall. The new building will also boast superior energy performance and is aiming for BREEAM Excellent certification.

CFL has chosen the joint venture Félix Giorgetti, CDCL and Poeckes to build its new head office, which will accommodate up to 1,200 employees.

Construction work on the new CFL headquarters began in summer 2023.

The first building will rise to a height of 31 m over eight storeys, while the second will have five storeys and be 21 m high.
There are a number of special features to this project, in particular the floors, which will be made of concrete from the first floor upwards - requiring particular care during construction to ensure a perfect appearance.
The assignment also includes the external joinery and facades, with the installation of 360 window frames and 4,000 m2 of brickwork.

Certified BREEAM Very Good, the 20,000 m2 complex comprises two buildings on a common trunk of five levels - two of which are underground - covering 5,000 m2.

Landimmo Real Estate, a member of the Landewyck Group, has entrusted F&eacute;lix Giorgetti and CDCL with the construction of Ettelbruck One, its Nordstad Administrative Centre. Located in Ettelbruck, this complex of almost 20,000 m2 of gross floor area is being built on a site steeped in history, where a former tobacco factory belonging to the Landewyck Group once stood. The new building, with its modern, avant-garde architecture, will bring together several of the country's public institutions and administrations, a medical centre, offices, shops and restaurants. This BREEAM-certified project will bring a new dynamic to the region. Structural work began in September 2023 and will be completed by the end of 2024.

For Landimmo Real Estate, Félix Giorgetti and CDCL are responsible for the shell of Ettelbruck ONE, a 2,000 m2 administrative complex.

The road will start at the "Op der H&eacute;i" roundabout and end 4.4 km further north, a few hundred metres after the new Hosingen-Nord interchange at Dorscheid. This will require the construction of a number of engineering structures: seven bridges (including two biotope structures and a wildlife crossing) and a cut-and-cover tunnel. In addition to the network of stormwater pipes for the road and the existing pipes that will be relocated, six water distributors and four retention basins are planned. The stripped topsoil will be reused to cover the embankments and other infrastructure.

The Hosingen bypass is intended to relieve congestion in the village centre, which sees almost 17,000 vehicles pass through every day. 

Freeing up the city centre

With a length of 325 m, the structure will consist of two tubes, each housing two lanes of traffic and as many pavements for pedestrians, separated by a reinforced concrete wall. The gauge will have a clearance height of 5 m for normal traffic and 5.50 m for exceptional transport. The technical supply and monitoring facilities will be located in a service building at the northern exit of the cut-and-cover tunnel. Construction of the cut-and-cover will involve major earthworks to a depth of 25 m, involving a total of 350,000 m3 of excavated material, all of which will be stored on site for re-use. With its rounded geometry, the construction of the structure represents quite a challenge. A 15 m long double carriage will then be installed to carry out the concreting of the cut-and-cover and its two tubes in phases.

Félix Giorgetti, in temporary association with Baatz, inaugurated the long-awaited Hosingen bypass construction project with the completion of its first lot: a 325 m-long cut-and-cover tunnel.

Félix Giorgetti is building a cut-and-cover tunnel for the Ponts et Chaussées as part of the construction of the Hosingen bypass.

The cut-and-cover tunnel is the first section of the Hosingen bypass.

The earthworks have started in September 2023.

The project was officially launched in June 2023 in the presence of François Bausch (Minister for Mobility and Public Works), Romain Wester (Mayor), Marc Ries (Ponts et Chaussées) and Paul Giorgetti.

The environment also plays an important role in this new route. In order to protect the local fauna, our teams have installed protective netting and will build in crossings under the road to allow frogs, in particular, to cross in complete safety. The Moulterbach stream will also be restored and enhanced, with a new bed meandering peacefully along the new road. In keeping with the environmental approach, 85,000 m3 of material from the earthworks will be processed on site and reused for the pavement boxes.

Protecting nature

This is why our teams have opted for a different methodology and will be using the top-down construction technique. The area will first be stabilised with 400 90 cm diameter piles, on which a covering slab will be placed.&nbsp;
Our teams will then come and dig eight metres below the structure to pour its 70 cm invert and its walls, representing 20,000 m3 of material to be evacuated.
<h3>A curved trajectory</h3>
This underpinning work is one of the greatest challenges of this project. Added to this is the fact that the trajectory of the trench is curved. A formwork carriage will be used to pour concrete over the entire height of the walls, in 10 m increments, to ensure that the curvature of the structure is respected.

La tranchée couverte étant située sur une nappe phréatique, cette partie représente l’un des principaux challenges de ce chantier.

Top-down construction

For many years now, the Route des Trois Cantons - the main thoroughfare for the municipality to the west of the capital - has been saturated. More than 8,000 vehicles pass through every day, slowed down by the PN5 level crossing, which is closed for up to 40 minutes an hour. The new bypass will provide a direct link between the municipalities of Reckange-sur-Mess and Bettange-sur-Mess, offering an alternative to the Route des Trois Cantons, which runs through the conurbation, and eliminating its level crossing for greater safety. With a length of 2.2 km, the route will include two lanes of traffic and two junctions at each end to ensure that traffic flows smoothly. It will comprise a number of structures and facilities:
<ul>
<li>a 125 m-long cut-and-cover tunnel, with two 50 m-long access hoppers, which will run under the roundabout towards Bettange-sur-Mess ;</li>
<li>an 85 m mixed metal and concrete footbridge for soft mobility;</li>
<li>a reinforced concrete overpass 15 m long and 5 m wide;</li>
<li>cycle paths;</li>
<li>a farm track;</li>
<li>hydraulic structures such as canals and a retention basin;</li>
<li>a crossroads;</li>
<li>noise protection measures such as noise barriers.</li>
</ul>
