Ok so I did some crude math which I admit is probably terrible.
The current height is 48 stories. I calculated each floor to be around 3 meters on average, from this I took the 48 story height and got a predicted total height so far of approximately 144 meters tall (this actually seems entire accurate).
In metric this means the building has another 144.3 feet to go.
It's currently 472.4 ft tall.
To put this into perspective., the MNP tower is only 1 meter shorter than Trumps Current height.
The building will be 188 meters tall, so in essence we have around 44 meters to go.
I added some data to show where the construction currently is on the building as a whole.
Each red dot up to the red line is 1 story/floor
