EXP3 (2013) --- the plan and the section

I have selected the plan of the Peak by ZAHA HADID. This plan has conveyed my idea of movement, which is about the change form of the movement and the speed of movement. And therefore I used the low gradient curve to represent the slow movement and vise versa; and the spatial change also represents the variation form of the movement. The strongest red coloured horizontal line is representing the cutting line on the plan and the black one represents the bridge.
