Marina Bay Sands Pool
Singapore
This unique structural masterpiece, designed by visionary architect Moshe Safdie, spans the width of all three soaring Marina Bay Sands hotel towers.
Project Overview
The Marina Bay Sands SkyPark appears to float like a ship across the top of the three hotel towers, and the pool spills over an astonishing 478-foot (146-meter) vanishing edge.
Featured in major magazines, television shows, and movies for its bold look and daring design elements, the Marina Bay Sands SkyPark in Singapore is a triumph of modern engineering. It is the one-hectare roof terrace that connects and sits atop the three 57-storey hotel towers. Measuring 478 feet long (146 meters), almost three Olympic swimming pools in length, the pool is the world’s largest infinity-edge pool at that height. It comprises of 422,000 pounds (191,416 kilos) of stainless steel and holds 380,000 gallons (1,438,456 liters) of water. In addition to the infinity-edge stainless steel pool, the SkyPark also consists of three large hydrotherapy spas, a wading pool, and a reflecting pool.
The success of the project lies in the inventiveness of the design and the inventive approach developed by the teams involved.
How were the SkyPark pools built?
The SkyPark is one of the most incredible technological feats in the pool industry, because of the consideration of the three towers’ movement by wind at that height and settlement in the ground over time.
Moshe Safdie, the leading architect for the Marina Bay Sands project, brought Natare on to handle the comprehensive and design challenges of the rooftop pools. The challenges were the combination of complex design parameters... Read More
The Challenges of Wind and Ground Settlement
With multiple pools sitting at a height of 650 feet (198 meters), it is imperative they can withstand any sort of natural ground movement and wind speeds.
Natare engineered the stainless steel swimming pool to allow for the swaying of the skyscrapers in every direction. There are four movement joints beneath the main pools, designed to help them withstand the natural motion of the towers, and each joint has a unique range of motion with a total range of motion of 500 millimeters (19.68 inches). The SkyPark is designed for wind pressures of up to 2.5 kPa (5,933 lbs./ft² or 250 kg/m²) and wind speeds of up to 105 ft./s (32 m/s).
In addition to wind, the hotel towers are also subject to settlement in the earth over time, so engineers built and installed custom jack legs to allow for future adjustment at more than 500 points beneath the pool system. The pool also adjusts to maintain its level flow along the horizon of the infinity edge, even as the three towers settle into the ground at different rates over the years. This jacking system is important primarily to ensure the infinity edge of the pool continues to function properly.
Marina Bay Sands SkyPark is arguably one of the world’s most challenging construction projects and certainly the most expensive stand-alone integrated resort property ever built. The SkyPark is a triumph of modern engineering with a bold look and daring design elements.
