"We have to be perfectly organised," explains our site manager. We are working along a busy road. The safety rules are therefore very strict. For example, you can't get within one and a half metres of the concrete blocks. Vehicle traffic is limited to 70 km/h, but you never know. A truck could hit the wall and cause serious damage."
Another requirement is the circulation of authorities. One lane must be accessible at all times to facilitate their intervention through the heavy traffic. An access road was therefore created on what stood as the hard shoulder, as well as refuge areas in case of a break down.
The final constraint was the motorway service area at the beginning of the section under construction. "The petrol station is the busiest in Europe, and closing it is not an option. We therefore had to find solutions to manage the traffic and maintain its activity."

The A3 widening project has some special features, particularly in terms of organisation, safety and traffic management.

Optimal safety

Elargissement A3 1

Widening of the A3 motorway on the Croix de Gasperich and the Living interchange section by Félix Giorgetti in the France-Luxembourg direction.

English

The major project to widen the A3 to 2x3 lanes between the French border and the capital began in mid-2022. This project is long awaited by the thousands motorists who use the route every day, and represents a major mobility challenge for the country. As part of this large-scale project, F&eacute;lix Giorgetti is in charge of the construction of the section between the Croix de Gasperich and the Livange interchange. More than two years of work are planned for this 4km section. Initially, the work involve extensive earthworks with the removal of more than 200,000m3 of material. For this purpose, our teams have been equipped with a Komatsu PC 490, which is ideal for large-scale work, and a Liebherr R926 Compact, which is controlled by a Leica GPS to ensure perfect embankment. The motorway widening also includes the laying of sewerage and multi-tube channels (for electricity and fiber-optic internet), the construction of foundations for future gantries, the laying of acoustic walls, and the creation of a 16,450m3 retention basin with a large vegetated area.

Félix Giorgetti is taking part into the major mobility project of the widening of A3 motorway.

More specifically, the works involve the complete runway rehabilitation to turn it into a state-of-the-art infrastructure, including the installation of a rainwater drainage network and a signalling system. The runway lighting is being replaced by the latest LED-based system in order to save energy and reduce the airport&rsquo;s CO2 emissions.
This project requires exemplary logistics since most of the work is carried out at night, when there is no air traffic. Up to 300 people work on the site at the same time and up to 300 tonnes of asphalt are laid every night. Everything accesses and leaves the site through a single point, namely the new E121 checkpoint, where all equipment, materials and machinery can be inspected. As expected, access is subject to extremely strict conditions.
As a result, every night shift needs to be perfectly orchestrated and every minute counts, since, come 6 am, the workers must clear the site before they leave so that the aircraft can use the runway.

Renovation work at Findel Airport

Key figures

Location

This is a large-scale project taking place from 2021 to 2023 on Findel Airport apron: the complete rehabilitation of the airport&rsquo;s only runway. With a length of 4,000&nbsp;metres and a width of 60&nbsp;metres, the runway is renovated in sections and only at night, from 11&nbsp;pm to 6&nbsp;am, so as not to disturb airport operations.
This project is scheduled over two years, as the work can only be carried out from April to September because of the local climate. Commissioned by lux-Airport, the project is being carried out by Somo Findel Airport, a consortium of construction companies made up of F&eacute;lix Giorgetti, Karp-Kneip Constructions and JCD Airports.

In 2021, Findel’s only runway gets a makeover. A large-scale project scheduled over two years because most construction work may only take place at night.

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.
With regard to lot 49-51, the 198m2 of facade were stabilised, as was the adjacent roof, and an adjoining gable of approximately 225m2 was pinned. For this project, which stretches from Avenue de la Gare to Rue du fort Neipperg, the earthworks proved more complex than anticipated, as our teams had to dig through very hard category 7 rock. It took a 100-tonne excavator ripper, a rock breaker, a disc saw and a milling saw to clear the 18,000 tons of excavated materials to be removed.
<h3>Work in restricted spaces, a real challenge for logistics</h3>
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.

Technical and logistics challenges

Luxembourg-City

This is a very technical project at 29-31 and 49-51 Avenue de la Gare in Luxembourg City. Two locations where F&eacute;lix Giorgetti demolished existing buildings to make room for a new mixed-use structure. 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.

At 29-31 and 49-51 Avenue de la Gare in Luxembourg-City, Félix Giorgetti is blending past and present.

The first section, "PC", is a 530 m cycle path and includes an underpass under the railway tracks on the ArcelorMittal site. The "Alley" section includes landscaping on an area of approximately 1.2 ha. The route continues via a cycle and pedestrian path that splits to accommodate ramps for people with reduced mobility and leaves cyclists on a constant slope. In the "Promenade" section, the ramps join up to the centrepiece of the project, the bridge. With a length of 1,200 m and an effective width of 4.5 m, it will rise up to 7.5 m. Plazas with an extra width of up to 8.5 m will be created to provide rest areas. Next, the "Schmeltz" section, with a running section framed by the steelworks and the railway tracks, and then the "Belval" section, which takes cyclists to the Avenue des Sid&eacute;rurgistes and/or the Avenue du Rock'n'roll. Pedestrians will be able to use stairs or lifts to reach the university district.

With a total length of 1.9 km between Esch-Belval and Esch-sur-Alzette, the PC8 is divided into five sections.

Construction of a 400-space park and ride, next to the Mersch train station

The structure built for the CFL is 125 m long and 30 m wide and extends over 5 levels. It is composed of a mixed structure with three reinforced concrete cores and a metal framework with collaborative panels. The last level is equipped with a green roof and photovoltaic panels. The fa&ccedil;ade is covered with gold and anthracite expanded metal panels. The station, located a few steps away, will be directly accessible via a tunnel. This turnkey project also includes the construction of a waterproof concrete sprinkler basin and a 2.5 m diameter, 60 m long retention canal in front of the car park entrance for rainwater collection.

In recent years, the town of Mersch has experienced a significant demographic growth. For this reason, the CFL has launched important initiatives in favour of mobility, including the construction of a 400-space park and ride, right next to the train station.

Aeroport Poste Controle04

Findel Airport

As part of the rehabilitation work on the Findel runway, a large number of external employees and vehicles, as well as a large volume of materials, have to pass through the highly secure airport site. Indeed, up to 300 people may be working on the site every night and 3,000 tons of asphalt be delivered. In order to be able to inspect everything, lux-Airport commissioned F&eacute;lix Giorgetti, in a consortium with Karp-Kneip Constructions, to build a new checkpoint.
The new building is designed to check people working on the site, materials and vehicles as they enter or leave the site. It includes four security gates, three for incoming vehicles and one for outgoing ones. A permanent timber building was erected between the security portals where employees of external contractors are checked and where a registration office issues them with daily badges.
There is also a conveyor belt to check personal items and a security gate. The checkpoint also includes a building where goods are checked using a very large X-ray machine, big enough to process whole pallets.
Once the renovation works are complete, the checkpoint will be used for other works that will be carried out on the taxiways (aircraft routes between the taxiway and the tarmac).

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.
