You did not send an area PLAN of the 142 storied structure. What is the total area of this structure? Is its floor area 300mx300m=90,000 sq.meter? Total vertical load, known as Dead Load (D.L) may be 500,000 ton for a tall building. The vertical load in this case is a staggering 5.5 t/m2. It is too big.
At least 17,000 piles are required to support an imposed vertical dead load of 500,000 ton. In this case load on the pile system is 29.4 t/pile. This load is alright for the friction piles with a length of about 30 m. However, it is impossible to place 17,000 piles in a SMALL 90,000 sq.meter space.
So, I ask what is the actual project area in sq. meter? This is the reason I wanted you to send the area PLAN of the main complex that the KPC group will build. I believe this structure is impossible to build because there is no bedrock at, say, (GL- 50m). Burj Khalifa is built on friction piles driven into a very very hard soil. Bangladesh lacks that kind of soil.
