Mobi\u2019Park TEC: the future logistics hub of the Li\u00e8ge network is taking shape<\/h3>\n\n\n\n

In Tilleur, near Li\u00e8ge, a large-scale construction site is in full swing: by June 2026, the former Chimeuse site will house the Mobi\u2019Park TEC, the future hub of the TEC network in Li\u00e8ge. Spanning a 10-hectare site, this new depot\u2014the second largest in Wallonia after Robermont\u2014is being built to support the development of the BUSWAY lines. Ultimately, it will accommodate 500 employees, 36 \u201cTribus\u201d buses, and around forty BHNS (Bus Rapid Transit) vehicles, both articulated and bi-articulated. More than just a simple depot, the Mobi\u2019Park will also become an ultramodern training center featuring driving zones, technical workshops, training rooms, and infrastructure for vehicle maintenance and cleaning. A prestigious project that is setting mobility in Li\u00e8ge on a new path... or rather, on new tires.<\/p>\n\n\n\n

Deschacht central to the site's sewerage solutions<\/h3>\n\n\n\n

To support the transition to a 100% electric fleet, Mobi\u2019Park TEC requires particularly sophisticated infrastructure. Cable conduits, extensive technical networks, water management solutions\u2014everything was meticulously planned to accommodate this new generation of articulated and double-articulated buses.\n\nThe project, led by the architectural firm Greisch and the engineering firm Lemaire (structural engineering and special systems), was awarded to the temporary joint venture Gal\u00e8re and Duch\u00eane. Deschacht took on two lots out of the twenty that make up the project.<\/p>\n\n\n\n

the construction of the buildings, 250 meters long, with administrative sections, maintenance workshops (pits, bridges) and the sewage networks beneath the structures. Here, in close cooperation with the site team, Deschacht completely reworked the drainage plans to integrate solutions tailored to the specific constraints of the site.<\/p>\n\n\n\n

the landscaping, a major share of the whole. This lot required a complete 3D BIM modeling, for which Deschacht made its digital library available. Thanks to this tool, the draftsman of the Gal\u00e8re-Duch\u00eane team was able to develop the entire sewer network with optimal precision.\n\nTo ensure technical conformity, Deschacht and sister company Collinet modeled the buffer basins and hydrocarbon separators in 3D to integrate them into the BIM model.<\/p>\n\n\n\n

Optimized technical choices starting from the preparation phase<\/h3>\n\n\n\n

During the preliminary phase, Deschacht participated in two technical meetings to identify the best solutions. Proposals for materials and solutions were submitted, discussed, and approved prior to the order.<\/p>\n\n\n\n

\u201cThis preparatory work allows us to optimize the technical choices from the beginning, in order to achieve efficiency gains in the further execution of the project,\u201d<\/p>\n\n\n\n

A strict approach to rainwater management<\/h3>\n\n\n\n

One of the biggest challenges of the project: the obligation to infiltrate all rainwater from the site \u2013 originating from roofs and floors. To achieve this, Deschacht supplied four infiltration basins with a total capacity of 3,000 m\u00b3, constructed using Columnbox and installed by partner Jean-Fran\u00e7ois Stassen. The modular design of these basins (60 cm high \u2013 and spread out horizontally) makes it possible to cover a large surface area and bear heavy loads thanks to the specific road structure above them.\n\nThe basins are equipped with valve chambers featuring overflow detectors to precisely control the discharge into the sewer system. An emergency overflow is provided, but the goal remains clear: to comply with AIDE standards and avoid overloading the public network.<\/p>\n\n\n\n

Custom technical equipment<\/h3>\n\n\n\n

The site is so large that it is divided into multiple hydraulic zones. Deschacht supplied:<\/p>\n\n\n\n
