Add in some additional height for the rooftop structure, and it might just come in somewhere close to 500'.
Again, this is just estimating, using a rendering instead of actual photos, and the rendering looks like it has squashed the images vertically, but the proportions might be more or less right.
Also consider that floors 1, 12, and 22 are taller than the others, so that will push it even closer to 500'.
Who knows.

Excellent work.

I agree that this thing will probably just barely scrape 500’.
