Water World at Ocean Park covered with a Texlon® ETFE Roof
Ocean Park is Hong Kong’s unique home grown, adventure themed, resort that opened in 1977. Hong Kong’s government approved a HK$10.64 billion plan to expand and reimagine Ocean Park with seven themed zones and 20 attractions. This included a new Water Park and Vector Foiltec is proud to be part of the redevelopment team delivering two large roofs for the new Water World buildings with 3,000 m2 of our Texlon® ETFE system.
Achievement: Steel Savings
Our scope of work included the design, fabrication, supply, and installation of the 3 layer ETFE cushion system. This included 40 integrated smoke vents all cladded with our ETFE. In addition, we were responsible for design and engineering of the steel structure supporting the ETFE and the two ETFE skylights. This also required submissions and approvals to Hong Kong Building Department for both steel and ETFE.
Vector Foiltec is a leader when it comes to lightweight architectural steelwork engineering. We chose to use built-up steel beams with varying radii. Therefore, it allowed us to taper the beam at the center span where force are lower. As a result, we achieved elegant, open, shell-like geometry with single layer steel structure and no trusses. Moreover, the efficiency of the steel structure offered substantial weight, cost, and time savings for the project team.
Challenging typhoon Wind Loads
Due the highly exposed coastal location of the new Water Park combined with typhoon wind loading and stringent requirements from the Hong Kong Building Department, we developed a special solution that incorporated discrete stainless-steel cables to provide additional structural restraint to the Texlon® ETFE cushions. The result was wide and long ETFE cushions allowing the most open and efficient solution possible, despite the extreme uplift loading.
Comfortable Atmosphere Under the Roof
The dot matrix printed outer layer ETFE foil creates a comfortable atmosphere for the visitors. Resulting in Ocean Park Water World being a great place to be. Moreover it provides a balance of natural light, thermal performance, and anti-glare properties and lets visitors forget that they are under a roof.
Earlier than this project, our Texlon® ETFE was used to create a panda house within Ocean Park. Therefore, all benefits have been extensively tested and were approved. A great tribute to us and our system. If you also want to benefit from our building envelope system: call us or send an e-mail.
