The building holds and will break several world records in the construction world, including: the tallest hotel in the world, constructed with the tallest clock tower in the world and displaying the world's largest clock face , the world's largest building floor area, and will become the second tallest building in the world upon completion, surpassed only by Dubai's Burj Khalifa upon its opening in 2012."
