Cantene developed the analysis for CMT, Italian consortium of Salini Impregilo. The entire TVF (tunnel ventilation system) was designed on the basis of the 1D analyses led by SES (Subway Environment Simulation system) under normal, congested and emergency conditions. Cantene performed also the CFD analyses for all the stations in order to verify tenability conditions along egress pathways and the respect of NFPA 130 -2014.
