Steel Project Engineering visits the Gare du Parc des Expositions construction site – Grand Paris Express
In recent days, Eng. Giovanni Costa, Eng. Leonardo Balocchi, Eng. Simone Pardini, and Eng. Simona Paone travelled to Paris for an on-site visit to the Gare du Parc des Expositions construction site, one of the key infrastructures of the new Line 17 of the Grand Paris Express.
Steel Project Engineering Srl is involved in the project as the company responsible, on behalf of Cimolai SpA, for the Detailed Design of the “Gare du Parc des Expositions” station and the pedestrian bridge connecting the surrounding areas to the existing railway and to the Parc des Expositions. The company is also in charge of the erection design of the station building, the pedestrian bridge structures, and the steel decks of the line works.
The station, intersected by the metro line viaduct (independent from the main building), is developed across 4 levels, with a total length of approximately 181 meters (without expansion joints) and a width of around 28 meters. A complex structure that combines steel elements, reinforced concrete works, and high-end engineering finishes such as the EFTE cushion roofing.
The pedestrian bridge, covering approximately 1,600 m², features a slender and articulated geometry, with ramps, elevators, and covered walkways. To ensure structural safety and dynamic comfort, specific dynamic analyses have been conducted to calibrate the TMD (Tuned Mass Dampers) and damping systems required for user comfort during operation.
We thank Cimolai for their trust and for the warm hospitality and welcome.
