The force of the building is almost completely on the 16 reinforced concrete bents. Each of the first three floors is tied directly to the bents and this exerts all the forces directly onto the reinforced concrete.
Use of horizontal planes is evident in the building. Each level has two planes that make up the total floor. Since the building stacks the top plane of one floor makes the bottom floor of the next level. The heavier lines represent the ground.
I thought the symmetry of the building was important and it is obviously shown in the Elevation. The buildings symmetry allows for each floor plan in the stack to be similar and therefore easier to navigate.
The way you move through the floor is important. When you exit the elevator you have the choice to walk straight the the area across from it or the choice to walk in a circular path around the core of the floor. each side of the floor has a break away that allows you to walk towards the personal corners of the floor.
The building is perfectly symmetrical vertically and horizontally in the floor plan. This allows the building to be easily navigated and learned. People can easily follow the flow of the building.
The spatial diagram I believe is the most important diagram of the floor plan. It shows specifically how the floor is laid out and it shows the distinct area of the floor.
