^ Well here is the former excavated site of the Capital @ Brickell which is where the CCCC Tower 1 will rise :

This is at the southern end of the Brickell district where the Capital project was only set to rise 809 ft. | 246 m.
I'm not sure if CCCC can get anywhere near 1,069 ft. | 325 m by the FAA.
