5. Fire resistance of structures

The tower's main structural elements and intersecting floors are :

  • fire-resistant to 2 h or R 120 for the structure ;

  • 2 h fire-stop or REI 120 for intersecting floors, in the sense of the tower's fire compartmentation.

No fire resistance is required for the lookout superstructure.
