Some New Finding in Weil Hotel

We are driving or walking around this construction site of Weil Hotel. However, only recently I found something unusual, which probably many do not realize it. What we see in building's construction, especially high rise building, reinforced concrete with steel skeleton within is the most common method to form building structure. Whereas solid steel beam structure is not so popularly applied in this country. And this is now seen in Weil Hotel where instead of steel bars, but steam beams are pointing upwards when the building growing vertically.
