Lets do the math on how much of the building is done comapred to how much its still got to go. Now this is from street level to Roof level.
Base height is 186.7 feet tall, Each office floor is 13 feet 4 inches tall, they are currently at the 44 th office floor, so lets do 13 feet 4 inches x 44 = 588 feet 8 inches tall. so now lets add the base plus the currnt progess of were they are at now. so 186.7+588= 774.7 plus the 8 inches so that would be roughly 775 feet tall plus the 6 foot splice. so the current final height is 781 feet tall
Now to the Roof height is 1368 feet tall.
Now to calculate the percentage done so far to the roof height,
781 divided by 1368 x 100= 57.09 percent. so we are at 57.09 percent to roof height which that would make 43 percent left to the top of the roof height.
well i hope i cleared and answered the question
