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.

With a total surface area of 14,000 m2, this office building will offer optimised, tailor-made and comfortable work spaces to promote the well-being, collaboration, exchanges and productivity of employees. Its BREEAM Excellent certification will guarantee its energy performance and sustainability. The Waves is also aiming for Well Gold certification and meets the standards for people with reduced mobility.

Excellent energy performance

A real architectural jewel, it consists of two volumes of asymmetrical heights linked by a large open interior courtyard that bathes all the spaces in natural light. It is four storeys high on one side and seven storeys high on the other. The entrance is set back slightly, at the junction of the two buildings on the north-east fa&ccedil;ade, while access to the 100 parking spaces, located on the two basement levels, is via the south-west fa&ccedil;ade. The Waves also houses a large 360 m2 inner courtyard that will welcome occupants and visitors in a pleasant, green setting.

Our partners

The Waves will take place on Rue Lucien Thiel, on the Kirchberg plateau, known for the large national and international companies that have chosen to establish themselves there. More than a simple business district, the Kirchberg is animated by a strong dynamic thanks to an important commercial, cultural, educational and residential offer. All this in a modern and welcoming environment. The address is also very well served thanks to the numerous public transport lines that will allow access to the four corners of the city, including a second tram line that will run at the foot of the building by 2035.

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.

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>

This solution involves prefabricating walls at Green Stone's production site in Bastogne, Belgium. These are then delivered to the site, ready to be installed according to an installation plan supplied by its design office. There are many advantages to this method, including speed of installation, time savings and improved working conditions for the workers involved. For example, a house can be built in one storey a day, compared with 10 days using the traditional method. The walls are also made of Poroton&reg;, a clay brick containing mineral wool insulation. These combined materials offer excellent thermal performance, making it possible to design homes that consume less energy. Thanks to its integrated insulation, there is no longer any need for external insulation, and fa&ccedil;ade renderings can be applied directly, saving even more time on planning.

To build our housing estate, we chose Green Stone technology, a high-performance solution.

High-performance, eco-responsible construction

Heading to Bascharage, southwest of Luxembourg. This section of the city of K&auml;erjeng in the canton of Capellen has nearly 6,000 inhabitants and is known for its National Brewery, one of the symbols of Luxembourg&rsquo;s terroir.
Located 16 km from Luxembourg-city, 14 km from Esch-sur-Alzette, 7 km from the Belgian border and 13 km from the French border, Bascharage is close to the country&rsquo;s biggest cities and to the main roads, while offering a calm and pleasant living environment.
In terms of mobility, the city has a train station (at Sanem and P&eacute;tange) and is served by numerous bus lines.
Cyclists can also use the two cycle paths that pass through the town.
All the amenities of a big city are also present; schools and high schools, banks and institutions or shops (Cactus, pharmacies, restaurants, gas stations, etc.). Everything is there, five minutes from your future home.

This new residential development is in a quiet, privileged location, set back from the main road between Avenue de Luxembourg and Rue des Pr&eacute;s. It comprises 15 single-family homes and three small-scale residences, each with four flats. With its soft colours, zinc roofing, large elegantly framed windows and green spaces, our teams have created a haven of peace, an invitation to well-being and a gentle way of life.

In Bascharage, Félix Giorgetti is developing and building the Am Leem housing estate.

In addition, two bridges will be built to carry the N13 under the A4, and the existing bridge on rue de l'Europe will be demolished. The retention basin connected to the Mess river below will also be redeveloped.
To ensure the peace and quiet of residents, 9,400 m2 of acoustic walls will be installed along the route.
As this is a busy road, traffic will have to be kept moving throughout the works. For this reason, the width of the carriageway and the speed limit have been reduced until the work is completed in February 2026.

9,400 m2 of acoustic walls

Especially as motorists currently have to make a diversion through the town to reach the capital. This has a major impact on the comfort and safety of local residents.
Direct access to GRIDX
Organised in several phases, the work being carried out by F&eacute;lix Giorgetti on behalf of Ponts et Chauss&eacute;es and the municipality of Mondercrange will initially involve redesigning half of the Esch-Luxembourg interchange, with the creation of two slip roads. These will be served by an oval roundabout 230 m long and 80 m wide, which will extend under the motorway and be equipped with traffic lights. It will also provide direct access to the Wickrange industrial estate and lead to GRIDX.&nbsp;

Inaugurated at the end of the 1960s, the Pontpierre interchange is one of the oldest in the country. Traffic has exploded since then, making it necessary to adapt the infrastructure, which has just three slip roads for entering and leaving the A4.

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.

CHL, the country's biggest hospital

Luxembourg's biggest hospital

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.

The new headquarters of the Big Four KPMG Luxembourg, is distinguished by its unique architecture, with a load-bearing facade made of Corten steel, formed by X-shaped elements. A second skin at 50&nbsp;cm from the load-bearing elements, is a curtain wall composed of triple-glazed windows.
The building has 4 basements for parking and archives, and 5 floors of 2,000m&sup2; to 2,700m&sup2; per level, providing almost 17,900m&sup2;.
Highly functional and offering great flexibility of layout, the building includes:
<ul>
<li>a large atrium in the centre, spanning all levels;</li>
<li>an entrance hall of some 340m&sup2;;</li>
<li>5 floors;</li>
<li>1 basement with some natural light;</li>
<li>3 basements for parking, utility rooms and archives;</li>
<li>bicycle parking close to the new tram line.</li>
</ul>
The building required BREEAM certification for its design, construction and operation, and was awarded a &ldquo;very good&rdquo; label.

It is one of the most remarkable buildings on avenue J.-F. Kennedy, the main traffic artery in Kirchberg.

<h3>Land in Kirchberg</h3>
KPMG Luxembourg was looking for a plot of land on the Kirchberg Plateau where it could become the owner of its own building, set up its headquarters there, and group together all its employees. In order to do so, the audit and consulting firm had to submit a tender to the Fund for the Urbanisation and Development of the Kirchberg Plateau (FUAK), the owner and manager of the space. F&eacute;lix Giorgetti had already taken on a similar mission during the creation of a new headquarters for law firm Arendt &amp; Medernach, also in Kirchberg. The construction company gave KPMG Luxembourg the benefit of his local roots, its experience and its in-depth knowledge of the market, institutions and local actors in order to lay the foundations of this ambitious project.
We guided our client through the entire process, starting with the preparation of the application for the FUAK tender which had to include financial, legal, technical and architectural studies of the project. This first step ended in success with the signing of the deed of sale.
<h3>Overall coordination</h3>
F&eacute;lix Giorgetti undertook the overall coordination of the development, construction, completion and interior fittings for the project, and acted as the sole interlocutor with KPMG Luxembourg in order to facilitate discussions and decision-making. More than just a source of support, F&eacute;lix Giorgetti proved a fount of valuable suggestions. We took the initiative especially when it came to the strong and distinctive identity of the building. Today, its load-bearing facade of cross-shaped Corten (a self-patinating steel) elements, glass and aluminium has become a real architectural signature and a landmark on the main traffic artery of Kirchberg.
<h3>A turnkey project</h3>
As a specialist in project development and management, F&eacute;lix Giorgetti mobilised all of its know-how and skills to guarantee the success of this project. Our teams were responsible for the entire development, construction, completion and fitting out of the building.
<blockquote>
It was an ultra-functional turnkey project, with the 1,250 employees of the audit and consulting firm moving in at the beginning of 2015.
</blockquote>

For KPMG, Félix Giorgetti led a complete project development, investment consulting and construction mission for a turnkey project.

Located on route d'Arlon in Luxembourg, the Moonlight building has 9,500m2 of office space. To allow the CSSF (Luxembourg financial regulator) to move into the premises and communicate with the neighboring building, which it also occupies, F&eacute;lix Giorgetti created a glazed walkway with a metal supporting frame.
The Moonlight building offers more than 9,500m2 of office space on 5 floors, as well as half of the basement on -1 as a kitchen and dining area. It has 4 stairwells, 2 elevators and 2 freight elevators. It also has a glazed walkway with metal supporting frame (13.5m long and 2.8m wide) connecting levels +2 and + 3 of the neighboring building, also occupied by the CSSF. It has 70 underground parking spaces.

Its width has been doubled from 20 to 42m to make it a multimodal bridge which will be used by cars, cyclists, the tram and pedestrians.
This 100m long structure spans 13 railway tracks, which makes the work very complex in terms of coordination, safety in and around CFL infrastructures and maintaining the flow of rail and road traffic.
<h3>Phased construction</h3>
Widening the bridge took place in two phases which involved sawing it lengthwise, demolishing and then rebuilding in two steps in order to maintain road traffic in this important link between the station area and Bonnevoie. The northern section was built first, followed by the southern section. The section was then handed over to Luxtram to start work in preparation for the tram.

The Pont B&uuml;chler was completely rebuilt to accommodate the new tram lines that will link the central station to the new national stadium through the Bonnevoie district. Objective of the work: to double the width of the structure.
The Pont B&uuml;chler is situated next to Luxembourg Central Station and is being widened to accommodate the new tram route that will connect the station to the new national rugby and football stadium at the Cloche d&acute;Or.

The work carried out by F&eacute;lix Giorgetti included the construction of a series of hydraulic and crossing structures called "grade separation", located at the intersection with the existing railway line north of Bettembourg. This crossing of the two railway lines also required moving the existing line by about 30 metres.
The entire grade separation work amounted to approximately 542, made up of 8 smaller works, each made up of 17 sections. This amounted to a total of 2,160t of framework and 600t of steel and a volume of concrete of around 5,000m3.
The works included moving the old railway line with earthworks and 12,000m3 of excavated material in 38 hours.

A 542m-long structure

Luxembourg - Bettembourg line

The construction of a new 7 km section of two-track line (with no stops) on a dedicated site as part of the new Luxembourg-Bettembourg railway link.
Starting from the future mobility hub at Howald, the line first crosses the A3 motorway south of the Gasperich interchange and continues west towards Bettembourg. It leaves this motorway north of Berchem, bypassing it to the west. It then passes under the RN31 (road) before crossing the existing Luxembourg-Bettembourg line in the Alzette valley by means of a grade separation. After crossing the Alzette, the new and existing lines join at the northern entrance to Bettembourg station.

A double winch crane was used to tilt the sections and columns over 8m high and weighing approximately 17t.
The walls at the entrances to the structure are covered with acoustic panels in order to reduce the sound effects of road traffic. The visible surfaces are water-repellent and covered with an anti-graffiti coating. The sidewalks are paved and fiber reinforced concrete slot gutters collect water and hydrocarbons. Earthworks were carried out in marly terrain.

Construction details

Route du Nord, Lorentzweiler - Blaschette

The Grouft tunnel is part of the Route du Nord, and connects the Plateau Haeschtreferbierg in the south to the Vall&eacute;e de l'Alzette in the north. It is 2,966 meters long.
It is made up of 2 separate tubes of unidirectional circulation.
The downtube towards Mersch has 2 lanes plus the exit ramp at the approach to the Lorentzweiler interchange. The tube to Luxembourg has been fitted with a third track for heavy goods vehicles.
The excavation was done by coming from the North and South sides of both tubes at the same time, in other words from 4 simultaneous fronts.
