I hope so. The new tower will be equipped with biological and chemical filters in the air supply systems. For optimum firefighting there are extra wide pressurized stairwells, multiple backup systems for emergency lighting (which failed in the Philadelphia Meridian Plaza high-rise fire in 1991) concrete protection for all sprinklers, additional stair exit locations at all adjacent streets and all of the buildings life safety systems like egress stairs, communication antennae, exhaust and ventilation shafts, electrical risers, standpipes and elevators are encased in a three foot thick concrete core for maximum protection. There is also a stairwell dedicated for emergency operations and protected tenant collection points on each floor.
So more steps towards the right direction are taken this time around.
