Turin-Ceres - Connection of the line with the RFI network - Equipment - SUBWAYSReferences_6038
The connection of the Turin-Ceres railway (Gruppo Torinese Trasporti) with the Turin railway network (Rete Ferroviaria Italiana) represents important underground works of approximately 4.2 km including the realization of a new twin-track tunnel along Largo Grosseto, the completion of Rebaudengo Underground Station and the adaption of an existing twin-track tunnel section. In addition to the structural design, Lombardi has developed the detailed design of the necessary electromechanical equipment to ensure the safety of users and the functionality of the railway’s operation and the underground stations. The design of Grosseto Station has been developed using Building Information Modelling (BIM) which allowed an efficient interaction between the different design disciplines, obtaining a high-quality result. The electromechanical system, designed with respect to the safety requirements of the Ministerial Decree 28.10.2005 “Safety of railway tunnels”, includes the medium and low voltage power supply, the normal and emergency lighting system, a complex ventilation and fumes control system for the underground stations, the pressurization system of the emergency exits, the fire detection system, the water distribution networks for the hydrants and the automatic high pressure sprinkler extinguishing system, the ventilation and air-conditioning of the technical rooms, the video surveillance as well as the intrusion protection and monitoring systems.

Alliance - HSL JunctionReferences_5377
The EOLE project (East-West Liaison Express) consists of the extension of the RER line (Réseau Express Régional) from the current Haussmann Saint-Lazare terminus station in Paris to Mantes-la-Jolie West of the Ile-de-France. The project includes a series of very complex underground works located in a particularly dense sector of the 8th Arrondissement of Paris. In particular, it consists in the realization of a vertical shaft, a series of cavities and two access branches that connect the shaft to the cavities. The underground structures involve the West junction of the Haussmann Saint-Lazare station, a tunnel excavated with TBM, tunnels to the East and West of the Gare de la Défense which is located under the CNIT (Centre des nouvelles industries et technologies). The shaft serves as access to the junction during the execution of the works and, on the other hand, the rescue services in the operation phase. An intersection ensures the connection between the shaft and the junction according to a Y scheme, dissociating the functions during the works from those related to operating. Lombardi is in charge of the detailed design of the junction between the new and the current line on behalf of the Alliance group, consisting of the construction companies NGE Génie Civil, Guintoli, Demathieu Bard, Pizzarotti, Franki Foundations Belgium and Atlas Fondations.
Grand Paris - Line 15 South - Segment 2 - Lot T2CReferences_6376
The lot T2C of the Line 15 is situated near Villiers Sur Marne in the south-eastern outskirts of the city. It includes: - two mechanized tunnels, principal and SMR lines, respectively 4.7 km and 2.2 km long; the main tunnel connects the Noisy Champs and Bry-Villiers- Champigny stations, while the SMR tunnel allows the connection between the main tunnel and the maintenance site; - an interconnection shaft of approximately 180 m (O807), 92 m of which are characterized by a traditional tunnel; - two TBMs launch shafts (O802P and O813P); - seven circular shafts used for evacuation and / or ventilation. Tasks: - Geotechnical design - Detailed and construction design of the underground cavern and of the shafts tunnel connections (by-pass). - Analysis of the effects induced by tunnels and station / shafts excavation on buildings - Design of driving parameters of TBM-EPB (Earth Pressure Balance)
Extension of Marseille’s metro line n°2References_6532
As part of the objective of developing the network of the track-reserved public transport network, the Aix-Marseille-Provence Metropole (MAMP), the Mobility Organizing Authority (AOM) in its territory, wishes to extend the Marseille’s metro network to the South-East. The extension stretches 4,8km from the station Sainte-Marguerite-Dromel to Saint Loup in the 9th and 10th districts of Marseille with 6 new stations. This extension is accompanied by the creation of a transportation hub at the line’s terminus as well as drawdown measures around each metro station. The consulting and project management mission covers: - The setup of the project program; - The elaboration of consultation with stakeholders supports; - The assistance in drafting tender documents for the project management of the operation and legal assistance to the contracting authority. The mission is realized in joint venture with the following companies: - Lombardi Ingénierie (leader of the consortium) – Project coordination and infrastructure expertise; - Geste Engineering – Transport systems and infrastructure equipment expertise; - Vera Broëz – Architecture and urban planning; - Cabinet Lanzarone – Legal assistance.

Metro Copenhagen Cityringen - Risk AssessmentReferences_560
The Copenhagen Metro City Ring is expected to be running in 2018 and will consist of two single tracks in a twin tunnel each approximately 16 km in length. The City Ring includes 17 underground stations (many of them located in the historical centre of the city) with island platforms, 4 cross-over facilities and 3 construction and ventilation shafts for transporting up to 234,000 passengers on an average work day. In the framework of Damage Risk Assessment for buildings neighboring the excavation sites, the effects of subsidence induced by the construction of deep underground stations were evaluated for the following sites: - Københavns Hovedbanegård - Frederiksberg - Nørrebro - Skjolds Plads - Poul Henningsen Plads - Gammel Strand - Rådhuspladsen The effect of tunnel-induced settlements was analyzed at Frederisksberg, Rådhuspladsen and Kongens Nytorv for selected important constructions. Most of the structures to be assessed were in fact masonry buildings positioned at short distance from retaining walls and/or located directly above the tunnel alignment. The excavation processes were modeled by means of finite elements analyses. In general, the soil-structure interaction was taken into account when calculating expected damage to the structures. In order to properly model the soil behavior, advanced constitutive laws were adopted. In some cases, in order to comply with the very strict limitations imposed by the Copenhagen municipality on the tolerated damage, mitigation measures were advised.
Preliminary studies for the extension of the Paris metro line 1References_6104
Context of the mission: The project foresees the extension of line 1 to the east between its current terminus and the Val de Fontenay station, developing over 6.9 km, segmented into 4.8 km of additional commercial line and 2.1 km of rear station. The project also includes the construction of 3 new stations: Les Rigollots, Grands Pêchers and the future terminus at Val de Fontenay. The complexity of the project lies in the many constraints to integrate: geotechnics; built environment; environmental constraints; railway route; constructive methods. Among the constraints are the numerous related projects: - Tramway T1 at Val de Fontenay; - Line 15-E of the Greater Paris; - Various real estate projects in the area of Val de Fontenay. The other major challenge of the project is to make a connection with the existing station at Château de Vincennes while preserving its operation and minimizing the impacts on the surface (Bois and Château de Vincennes). Lombardi’s tasks: The consortium consists of TRACTEBEL (lieader of the consortium) - VERA BROEZ (architect) - LOMBARDI. Lombardi's services consist in the realization of the Schematic Layout of the extension (equivalent to preliminary studies), prerequisite to the detailed design of: - The tunnel and ancillary works (Civil Engineering and Equipment); - The stations (Equipment and Ventilation); - The railway track.
