build in velocity is both performance and construction. Constructing means constant geometric analysis of the performative requirements of a design problem. Especially when considering ski jumps and bobsled runs, the design is directly dependent on structure and construction by standardized guidelines, which define the core function. These vectors are generating geometrical expansion and thus form the structure of the architecture. The design is created in the process of constructing dynamic load cases and the selection of appropriate materials. These structures, as architecture, are adaptable, changeable, manipulable. The form of the architecture is a state created by different levels of speed, acceleration and movement.
