Rail projects
RATP - Extension of line 14 of the Paris metro - Lot T01 - Porte de Clichy station (2014-2015)
G3 engineering assignment
Design of the screen walls for the main station and its three entrances.
- Dimensions of the main station: 120 m linear x 30 m wide
- Dimensions of diaphragm walls: 1.5 m thick x 55 m deep
Taking into account all phases of construction and commissioning of the site. Preparation of all calculation notes and supervision of formwork and reinforcement drawings. Direct exchanges between the project management team (Systra) and the contractor (Eiffage Fondations)
Tunnel design for the new L15 SO metro line (Paris)
Ingerop España entrusted us with the calculation of settlements in the adjacent structures and deformations around the tunnel using the convergence-confinement method for 6 tunnel sections. The calculation had to take into account the existing works, so a finite element analysis (Plaxis 2D) was chosen.
Société du Grand Paris (SGP) - Line 15 West (2016-2017)
Pre-project studies
Finite element modelling of around ten calculation sections for the Grésillons and Agnettes stations.
30 m deep stations in a Parisian geological context. Analysis of the complex construction process, taking into account the different water tables to take account of possible flooding.
Paris tramway line T6 - Retro-analysis of the walls (2014-2014)
Analysis of the behaviour of the cast walls in relation to the design studies.
Levallois Perret maintenance workshop (2012)
Design of micropiles for railway pits and track pits.
Saint Martin Le Vinoux tramway - (2011-2011)
Design of a wall of piles parallel to the SNCF tracks, producing the calculation notes and checking the formwork and reinforcement plans.
Extension of metro line B at Oullins (2011)
Design of crane foundation piles under various load conditions (lateral and axial forces on the piles).
Prado Sud tunnel - Lyon (2011)
Design of a moulded concrete wall: calculation note and checking of formwork plans.
