[CONCEPT]

Architectural and artistic works that engage with the landscape often respond to the immutable aspects of nature. This project, however, presents a metaphor for nature as an entity characterized by perpetual action, with waves that symbolically rise and fall in an endless cycle of creation and dissolution. The aim of this project is to architecturally reconstruct these waves, encapsulating their ‘change in density’—evident in the breaking features—and ‘motility’—seen in the features that move ceaselessly. These dual characteristics form the core elements of the work.

In this context, I propose a bridge spanning the sea. This bridge, however, diverges from traditional infrastructure meant for traffic. It functions as an ‘integrated energy unit,’ harnessing ‘solar energy’ and ‘wave power’ directly from nature. Additionally, it incorporates systems to filter contaminants from seawater pollution and mitigate destructive forces. These functional attributes define a new model for waterfronts that is socially and environmentally conscious.

The bridge’s kinetic mechanism is driven by a pair of pipes equipped with three rotary joints. These pipes pivot to create passage for ships, and the torque generated by their rotation initiates movement and activates several functions. The bridge extends for one kilometer and is segmented into four parts. Its surface is comprised of photovoltaic cells, the density of which can be adjusted according to HOBERMAN’s theory. This responsive surface also serves to attenuate the strong sea winds common near harbors.

Wave power energy plants, attached to the bridge’s underside, harness the ocean’s energy to produce electricity. The rotation alternately submerges and elevates parts of the bridge, with the submerged sections filtering pollutants from the seawater at regular intervals. Within the pipe structure, three helical passages twist like a screw, providing pedestrians with a gently changing perspective as they move through the rotating bridge. This dynamic experience compensates for any disorientation caused by the rotation.

Stations placed along the bridge serve as connection points and house the driving mechanisms for the rotation. Submarine observation platforms are strategically located to offer unique underwater views. The bridge is more than a simple conduit between two points; it is a pedestrian thoroughfare rich with diverse events. It includes various amenities, such as street furniture for rest and observation platforms, enhancing the user experience.

Moreover, the bridge’s distinctive wave-like shape leaves a lasting impression of the ‘LANDSCAPE,’ offering an aesthetic that harmonizes with the surrounding environment.
