Rosny sous Bois batching plant

Upgrading public transport is a major factor in the development of the Greater Paris Urban Area (Grand Paris). One related project is the extension of metro line No. 11 from its Mairie des Lilas terminal to the Rosny-Bois-Perrier station on RER rapid-transit line E, for which SATM Grands Travaux is supplying 130,000 m3 of concrete from its batching plant in Rosny sous Bois.

Infrastructures concerned by the three contracts for the Rosny sous Bois project

One work package concerns construction of a 3-km-long, 7.95-m-diameter circular tunnel, 4 stations, and three ventilation and fire-access shafts. A second package concerns construction of a 245.5-m-long twin-track tunnel connecting the future Serge Gainsbourg station to the Les Lilas maintenance workshop, together with installation of plant rooms. And the third contract is for construction of an impressive 580-m-long viaduct on the above-ground section of the metro line at the Coteaux-Beauclair station in Rosny sous Bois, a striking structure that is bound to become emblematic of Line 11. The works are scheduled for completion in November 2021.

Noisy le Grand batching plant

Line 15, the first of the Grand Paris Express system aimed at reducing travel times in the suburbs of the Greater Paris Area, will ring the area: its construction is nothing less than historic.

Under this project, SATM Grands Travaux is supplying the concrete necessary for construction of the Noisy-Champs station on Line 15. In addition to the very modern 156-m-long station itself, SATM Grands Travaux is also involved in the construction of the 255-m-long stabling and turnaround facility ahead of the main station, as well as construction of a 29-meter-long road bridge across the RER A rapid-transit lines. For this, the workforce of SATM Grands Travaux is producing a total of 113,068 m3 of concrete. Project handover is scheduled for September 2022.

Our Achievements

Champigny sur Marne batching plant

As part of construction of Line 15 of the Grand Paris Express system, SATM Grands Travaux is producing concrete for another two sites : the TBM-driven tunnel between Noisy-Champs and Bry-Villiers-Champigny, and the Champigny sur Marne maintenance and stabling facility (MSF).

The works for the 7 kilometers of tunnels involve excavation of starter shafts for each of the two TBMs driving the main tunnels, a maintenance turnout, and 7 sets of ancillary works. The work being staged from 2017 to the end of 2021 requires a total of 122,550 m3 of concrete.

The MSF project requires 61,118 m3 of concrete for construction of an 85-m-long transition, a 22,000 m² transfer and run-through/stabling hall, 17,000 m² of maintenance workshops and plant rooms, and a 10,000-m² service building. For the two work packages, therefore, SATM Grands Travaux is producing more than 180,000 m3 of concrete on a third-party site.
