Starting with a two-lane mountain tunnel, the engineering consultants for the MTFVTP designed, managed construction for, and maintained a one-of-a-kind facility that allowed testing of seven ventilation concepts and was capable of withstanding nearly 100 fires - four of which were 100 megawatts (MW) 341 MBtu/h).
