5 Thesis The Bank of China Building is the most unique work of Structural Art of its kind, ever. IM Pei has the ability to create simple yet unbelievably exciting forms which enthrall the viewer and satisfy the ideals of Society and Symbolism. Peis genius however would never be portrayed if not for the incredible technical imagination of Leslie Robertson, responsible for the Scientific aspects of the building.
