The TDVEC is a building with unique and specific functions that is of an unprecedented scale in the world for building of this type. The challenge is huge to create a building that is capable of housing all those complex functions in relatively small and irregular site with a lot of site constraints. Efficiency is of the utmost importance in handling the influx of a maximum flow of 1000 vehicles per day. To accommodate the sheer operational space within the irregularly shaped and congested site, the team has devised an innovative driveway arrangement – a double helical ramp system to resolve the vertical vehicle traffic as well as eliminating the potential vehicular conflict due to head-on traffic in most vehicle-oriented building. Wrapping this logically planned, machine-like building is a sleek façade design is inspired by the metaphor of fully synchronized machines. The two-tone slants fins is a subtle interpretation of the essence of the building which serves as a powerhouse for the region to drive the flow of the energy, representing itself in the form of vehicular movement inside and surrounding the facilities as symbolised by the streamlined building form and intricate details.
