RTM
Goal : Improve the ventilation used for smoke extraction across the stations, maximising performance of the existing system while limiting works in the passenger area.
Scope : Performance-based approach applied site by site — numerical simulation verifying that simple adaptations could be proposed at each station. Extended support during works and up to acceptance testing (aeraulic and smoke extraction), with final tuning.
SNCF
Goal : Rationalise the network's ventilation resources in the event of a tunnel fire.
Scope : 1D numerical study to establish high-performance ventilation scenarios for both smoke extraction and sanitary modes. Adaptation of the station smoke-extraction doctrine for the operation of new hybrid rolling stock.
SMTPC
Goal : Develop an airflow regulation tool in both tunnels to strengthen fire response.
Scope : 1D numerical modelling of the regulation, development and platform testing (desktop PLC) to minimise on-site test time (limiting tunnel unavailability), deployment and acceptance testing.
Colas Rail
Goal : During execution, revise the smoke-extraction scenarios following geometric changes to the as-built structures.
Scope : 1D and 3D numerical modelling, flow measurements, smoke-extraction tests.
QDVC (Vinci)
Goal : Qualify ventilation equipment, systematic smoke-extraction scenario testing in tunnels and stations.
Scope : Velocity and flow measurements, smoke-extraction tests.
Stucky / Forces motrices Hongrin-Léman
Goal : Ventilation system and smoke-extraction scenario study; integration of Veytaux I into the overall ventilation scheme.
Scope : Design and sizing of the mechanical ventilation and smoke-extraction system, coherent with the operation of the existing plant.
Bouygues
Goal : Measurement of underground car park ventilation intakes' wind exposure; façade exposure study for the choice of exterior louvres.
Scope : Building modelling and in-situ measurements for façade element sizing and underground car park ventilation optimisation.
Hydrostadium
Goal : Ventilation of a transformer room.
Scope : Ventilation study for a technical room in a hydroelectric production facility.
Twenty years of testing, measurements and on-site experiments — wind tunnel, Chardot-type fires, tunnels, stations, hydroelectric plants and public buildings in France and around the world.
