Please describe the project specifications

Chaka Salt Lake‌ is located in Chaka Town, Ulan County, Haixi Mongol and Tibetan Autonomous Prefecture, Qinghai Province. "Chaka" is a Tibetan word meaning "salt pond," while its Mongolian name "Dabsun Nur" translates to "sea of green salt." Renowned for its mirror-like surface that vividly reflects the sky, snow-capped mountains, and surrounding landscapes, the lake is celebrated as the ‌"Mirror of the Sky." Chaka Wind Station‌ (the sightseeing railway station), situated within the Chaka Salt Lake Scenic Area, serves as the core project of the transformation and upgrading of the scenic spot.
The project innovatively transforms the abstract concept of ‌"wind"‌ into a tangible architectural experience. Utilizing steel and membrane structures, it creates a ‌free-form curved roof‌. A tricolor fabric system employs a ‌mosaic-inspired color algorithm‌ to achieve gradient effects. Combined with the lake's strong wind conditions, the structure resembles dynamic ribbons from afar, breaking the static limitations of traditional membrane structures and allowing visitors to ‌"see the wind and hear the wind."
Chaka Wind Station is remarkable for its irregular roof structure with dominant curves, which is topped with two special red colour PTFE fabrics GFM-21-LT and GFM-21 covering respectively 3,077 sqm and 3,171 sqm. These translucent membranes bring controlled natural light into the core of the station, while delivering high mechanical resistance and an ultra-long lifespan. The PTFE tensile covering in red is complemented by the addition of 4,125 sqm of brightly-coloured Soltis 86 Colour squares, intended to flap in the wind like the leaves on a tree, and tied around a series of large funnel-shaped support columns, where colour and shape come together to create a uniquely creative architecture.
The membrane structure unit is prefabricated in the factory. The membrane is precisely spliced with 1292 customized steel units, and the force is coordinated and stressed; On-site zero-welding installation to avoid polluting the salt lake water body. At night, the "Light up the Red Scarf" mode reduces light pollution through smart lighting, which meets the requirements of the Star Reserve. The construction period is only 64 days, which greatly reduces the disturbance to the Salt Lake ecology. After the project was officially put into operation, it became a landmark check-in point in the scenic spot, receiving up to 20,000 tourists in a single day.
