The Yas Hotel project opened in Abu Dhabi, UAE On Nov 3 2009 after a preliminary opening coinciding with the inaugural Ethiad Formula 1 race held on October 30. A 500-room, 85,000-square-meter complex constructed by Aldar Properties PJSC. Asymptote was awarded the commission to design the buildings and environs from a closed competition two years prior to the official opening.Photos by Bjorn MoermanThe Yas Marina Hotel is located within the Yas Marina Circuit, Abu Dhabi. It is the first new hotel in the world to be built over an F1 race circuit. The hotel’s exterior surface is designed as an environmentally responsive skin that by day reflects the sky and surroundings and by night is lit by a full color changing LED lighting system that incorporate video feeds that are trasmited over the entire surface of the building.The Yas hotel, a 500-room, 85,000-square-meter structure made up of two twelve story hotel towers linked together by a monocoque steel and glass bridge A Grid Shell structure that both cross above and over the Yas Marina Circuit F1 race track.Asymptote created and conceived of the building as an architectural landmark embodying key influences and local and global inspirations ranging from the aesthetics and forms associated with speed and spectacle to the artistry and geometries that form the basis of ancient Islamic art and craft traditions.Of architectural and engineering significance is the main feature of the hotelʼs design; a 217-meter expanse of sweeping, curvilinear glass and steel covering that is made up of 5,800 pivoting diamond-shaped glass panels. This Grid-Shell component is a key aspect of the overall architectural design and significance of the project by producing an atmospheric-like veil visible from miles away.The two hotel towers, one being set within the race circuit, and another placed in the Marina itself, are physically linked by a sculpted steel monocoque bridge construction that passes above the Formula 1 track. The bridge along with the Grid-Shell visually connect and fuse the entire Yas Hotel complex. The Yas Hotel was designed by Asymptote to become a significant and important landmark for Abu Dhabi. The pixelated lighting design by Asymptote in collaboration with Arup Lighting creates a dynamic appearance at night, with colours flowing smoothly across the double curved surface. says in a press release“The hotel embodies various key influences and inspirations ranging from the aesthetics and forms associated with speed, movement and spectacle to the artistry and geometries forming the basis of ancient Islamic art and craft traditions, a perfect union and harmonious interplay between elegance and spectacle. The search here was inspired by what one could call the ‘art’ and poetics of motor racing, specifically Formula 1, coupled with the making of a place that celebrates Abu Dhabi as a cultural and technological tour de force.”ClientAldar Properties PJSC, Abu DhabiLead ArchitectAsymptote Architecture: Hani Rashid and Lise Anne CoutureProject Directors: Mick McConnell, Andrew DrummondProject Managers: Theo Sarantoglou Lalis, Constantin Doehler, Matthew UtleyProject Team: Danny Abalos, Keehyun Ahn, Sebastian Andia, Bernardo Crespo, Greg Derrico, Reed Finlay, , William Garcia, Armand Graham, Moritz Greiling, Justine Groves, John Guida, Kurt Hanzlik, Robert Hendrick, Tyson Hosmer, Robert Ivanov, Jeremiah Joseph, Feby Kuriakose, David Lessard, Sophie Luger, Brooks McDaniel, Jonathan Podborsek, Klaus Ransmayr, Ben Ritter, Greg Spaw, Ariane Stracke, Kyle Stover,Tae-Hyung Park, Martin Zangerl, Christoph ZieglerAssistants: Manca Ahlin, Phuttipan Askawool, Ali Baker, Christoph Boeckeler, Julie Bogdanowicz, Remi Chevrillon, Cluadia Friesz, Hiroe Fujimoto, Daniel Angulo Garcia, Daniel Gillen, Avital Gourary, Richard Heger, Katharina Hieger, Julia Hoins, Ji Young Kim, Siyoung Kim, Jonathan Kleinhample, Adam Koogler, Rolando Lineros, Brendan Maloney, Mirai Morita, Tom Raymont, Friedrich Rohde, Sander Schuur, Greg Spaw, Jeff Walker, Robert Wehinger, Michael Whalen, Ann Wright, Margaret YooCommercial Director: Chris DeluskyConsultantsLocal Architects: Dewan Architects & Engineers, Abu Dhabi Tilke & Partners W.L.L., DubaiStructural Engineers: Dewan Architects & Engineers, Abu Dhabi ARUP, New YorkGridshell Engineers: Schlaich Bergermann und Partner (SBP), Stuttgart Waagner-Biro, ViennaGridshell Building Information Modeling (BIM) Consultant: Gehry Technologies, Los Angeles & New YorkGridshell Lighting Consultant: ARUP Lighting, New York, Amsterdam ( Rogier van der Heide, Brian Stacy and Richard Fisher )Façade Consultants: Front Inc., New York TAW & Partner, HamburgLink Bridge Engineers: ARUP Bridge, New York Centraal Staal, Groninge, The NetherlandsInterior Design: Consultants: Jestico + Whiles, London Richardson Sadeki, New York De8 Architetti, Bergamo, ItalyLighting Consultants: LAPD Lighting Design, Hertfordshire, UK Bartenbach LichtLabor GmbH, Innsbruck, Austria Red Engineering Middle East, Dubai ARUP Lighting, New YorkGridshell Wind Engineers: Wacker-Ingenieure, Birkenfeld, GermanyGridshell Node Housing Consultant: Billings Jackson Design, LondonMEP Engineer: Red Engineering Middle East, Dubai, UAELandscape Design: Cracknell Landscape Architects, Abu DhabiAudio, Visual & I.T.
