Problems faced :
1) super hot and not to mention BURNING sun !! We turned into roasted human sate after measuring the site. One of our group member even fell sick the next day~ ><''
2) Maybe due to the disturbing sun, our measurement was a bit off. So we measured it again and again to get it right.
3) Curved staircase, super hard to sketch it right~ ><'



Perspective 2 from site.
End of submission ONE~ cheers*
