Rain Oculus Marina Bay Sands, Singapore A large whirlpool forms inside a 70-foot diameter acrylic bowl and falls 2 stories to a pool below. The artwork, a collaboration with architect Moshe Safdie, functions as both a skylight and a rain collector. The rain water is recycled back to the whirlpool and also fills a canal that runs through the atrium. The pumps that direct water into the bowl are turned on and off a few times an hour so the whirlpool is always changing in shape and intensity. At peak flow rates there are 8000 gallons per minute falling through the atrium and 200 tons of water swirling around in the bowl. Extensive prototyping and engineering went into integrating the artwork into the structural and mechanical systems of the building. Completed in 2011.
The Helix Bridge at Singapore’s Marina Bay was inspired by the geometric arrangement of a DNA strand, resulting in a walkway that is enclosed by opposing double-helix structures of stainless steel.
Spanning the Singapore River from the city’s central business district and bayfront area, the 280-metre-long twisting bridge allows pedestrians to walk its curved deck from one side of the river to the other.
The Helix Bridge wanted to be a more delicate and lightweight alternative to the vehicular bridge that was also part of the project. The pedestrian bridge is curved in plan to distance foot-traffic from cars, while also enabling pedestrians to connect from one bridge to another in the middle.
The bridge connects with attractions including the Marina Bay Sands complex and the National Performing Arts Centre. You can also gain sweeping views of other landmarks and the bay on the four viewing platforms that cantilever out from the bridge.
Ribbons of LED lights illuminate the bridge by night, emphasising the two twisting helix tubes. Canopies made of fritted glass and perforated steel mesh offer shade from the tropical sun.
The bridge is 285-metres long, made up of three 65-metre spans and two 45-metre end spans.
