There are very many design difficulties with the tallest tower with the uneven top and a very sleek base with litte space for elevators.

the mounting for the window cleanign system and the solar panels wich cower the top is also amazing. the solar panels will generate enough energy for 5 thousand households according to the program

and there are also two umbrella shaped sections of steel rewbar connected to the core that work as vibration dampers that send the stress out into the outer support collums wich then sends it down.

And the work they put into the mall is redicilous very much of it is made in the old way and the outer surfaces is made of a glass concrete mix so that it can withstand the sandstorms better and all of it must be surface teated by hand after being hung up because the suface is to uneven and deep.
