<div><span lang="EN-US">The construction site will also include a major earthwork project, involving some 140,000m<sup>3</sup> of excavation and backfill in order to level out the terrain. This will start with stripping the topsoil. A maximum of the extracted material will be reused.</span></div>
<h3><span lang="EN-US">Reinforcing the soil</span></h3>
<div><span lang="EN-US">As the quality of the soil was not sufficient to accommodate the road structure, our teams called on a special machine to create 2,800 ballasted columns. This technique consists of reinforcing the soil by digging shafts - the columns - and injecting ballast, a material that is both permeable to water and has high mechanical properties, into them at high pressure. The column is made throughout the loose soil layer and descends to a more resistant layer of soil. In this project, the ballasted columns will reach a depth from 6 to 8 m.</span></div>

<p>"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."</p>
<p>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.</p>
<p>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."</p>

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.

<p>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.<br /><br />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.<br /><br />Initially, the work involve extensive earthworks with the removal of more than 200,000m<sup>3</sup> 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.<br /><br />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 16,450m<sup>3</sup> retention basin with a large vegetated area.</p>

<p style="font-weight: 400;">Started last November and March, the work must be completed by September 2023 and spring 2024 respectively to prepare for the arrival of the tram. Our teams are fully mobilised, with increased staffing levels and a six-day-a-week schedule to complete this important mobility project as planned.</p>

The main challenge of these assignments lies in the schedule.

Stronger workforce for an ambitious schedule

<p style="font-weight: 400;">This section will also require the construction of a retaining wall approximately 135m long and 11m high and 120,000m<sup>3</sup> of fill to absorb the steep slope of the terrain. The main component of the lot, this structure is made of reinforced earth (a structure that combines backfill, reinforcement and a modular system of prefabricated concrete panels) and will be composed of reinforcement up to 8m long.</p>
<p style="font-weight: 400;">Lot 2a involves sinking under the motorway for the passage of networks and the construction of a covered trench. This 375m long structure with its hoppers will open the way for the tram under the Senningerberg interchange.</p>

The new road will also allow motorists to drive directly to the A1 towards Trier.

Paving the way for the tram

Bvd Hohenhoff01

The works include the redesign of the Senningerberg interchange, the creation of part of the Höhenhof boulevard and the construction of a cut-and-cover tunnel.

<p style="font-weight: 400;">Lot 1 consists of the redevelopment of the Senningerberg interchange, with the construction of part of the new H&ouml;henhof boulevard and the creation of a connecting road between the boulevard and the route de Tr&egrave;ves. This work will turn the area into a real mobility hub, including a P+R, a bicycle parking area, a bicycle path and a tram line with bus and tram stops.</p>

In the context of the arrival of the tram to the Findel by the end of 2024, the Ministry of Transport and Mobility has entrusted Félix Giorgetti with the realisation of lots 1 and 2a.

<p>After the rehabilitation of the Findel runway, the construction of a retention basin and the E121 security post, to name but a few, this is a new project carried out for lux-Airport that has been successfully completed.<br /><br />In addition to the initial order, the construction of a 250m<sup>2</sup> guardhouse and the external works (including the user car park and the extension of the taxi park on the runway) were also added. The latter were carried out in joint venture.</p>

Further works

<p>In addition to the hangar, the structure includes workshops, storage areas and an administrative building that will accommodate the 160 or so Luxair Technics employees and support future growth.</p>
<p>The project started in May 2022 and was completed in record time, with the structural work delivered, as planned, less than a year later, in March 2023.</p>

Supporting staff growth

Hangar Luxair01

The hangar is located next to the imposing Cargolux headquarters.

<p>This new infrastructure plays a decisive role for the Luxembourg airline.&nbsp;<br /><br />The new facility, located southwest of the runway, will replace the historic hangar built in 1951 in Neudorf and will be able to accommodate, for example, two large and one small commercial aircraft.</p>
<p>In this huge maintenance hall, the slab - made of 300 t of reinforcement and 1,800 m3 of concrete - is equipped with an underfloor heating system, and energy supply manholes called "PITS" (compressed air/electricity/kerosene vapour extraction) will optimise the work of the technicians.</p>

<p>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 CO<sub>2</sub> emissions.</p>
<p>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.</p>
<p>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.</p>

<p class="p1"><span class="s1">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.</span></p>
<p class="p1"><span class="s1">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.</span></p>

<p>For lot 29-31, the teams stabilised the 370m<sup>2</sup> of facade and pinned the two adjoining gables over an area of 880m<sup>2</sup>. The existing buildings were demolished and 28 tie rods installed under the facade to be retained.</p>
<p>The project consists of two underground levels and seven above-ground levels. It includes 2,300m<sup>2</sup> of offices and 876m<sup>2</sup> of retail space. The structural work began in late September 2021 and is scheduled for completion by the third quarter of 2022.</p>
<p>With regard to lot 49-51, the 198m<sup>2</sup> of facade were stabilised, as was the adjacent roof, and an adjoining gable of approximately 225m<sup>2</sup> 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.</p>
<h3>Work in restricted spaces, a real challenge for logistics</h3>
<p>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.</p>

Technical and logistics challenges

20211210 Avenue Gare 3 D 2

Luxembourg-City

<p>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.</p>

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

<p>As for the construction itself, the main building as well as the offices are composed of a metallic frame with floors in collaborative steel tanks, the external elevations are in reinforced concrete poured on site and in premurs in the interior. For the offices, the concrete slab is smoothed and left rough.</p>
<p>The seven-storey, 40m high hotel is made of prefabricated sandwich panels measuring 8.10 x 3.05m and weighing up to 12 tons for the heaviest. These are concrete walls that include both insulation and finishing. These structural elements save a lot of time.</p>
<h3>The spiral ramp, a real technical challenge</h3>
<p>This is the most spectacular element of the project: the spiral ramp. &nbsp;With a diameter of 25.5m and a height of 37.5m, the structure is impressive.&nbsp;</p>
<p>The two-way structure serves to distribute the eight parking levels of the park house as well as level -1.</p>
<p>700m&sup3; of concrete were needed to build the 24cm thick reinforced concrete walls. &nbsp;The rounded structure, made of reinforced concrete cast in place, requires special formwork using Sateco CTR formwork to achieve the curvature. It also includes over 57 tons of reinforcement.</p>
<p>Once the elevations were completed, the steel frame was installed, as well as the steel decking, and finally the concrete was poured for the slab to form a ramp with a 6.6% slope. &nbsp;</p>

The scale of the site is such that it has been divided into four zones. In total, up to 85 people, workers and supervisors, work in this huge hive where the complex is gradually emerging from the ground.
