Stone contributes to LEED certification for new Las Vegas landmark
July 1, 2010
Bringing together casino gaming, nightlife, restaurants, hotels, retail, entertainment, residential communities and more, CityCenter aims to be the heart of the famous Las Vegas Strip and a one-stop destination to visitors and residents. The result of a collaborative effort reached by eight renowned architecture firms, the project features several buildings that have been awarded LEED Gold certification by the U.S. Green Building Council - the highest level of LEED achievement given to any hotel, retail district or residential development in Las Vegas. Material selection - including extensive use of stone for the interior and the exterior - was a contributing factor in this achievement.
“CityCenter bridges the vitality of Las Vegas with the experiences travelers seek when they visit great cities around the world, whether London, Hong Kong or San Francisco - spectacular architecture, culturally significant art, great public spaces, sophisticated hotels, unique restaurants and incredible amenities,” said Bobby Baldwin, president and CEO of CityCenter. “It is an evolutionary destination that aims to transform Las Vegas as a new symbol at its core, like the Guggenheim in Bilbao, the Pompidou in Paris or the SONY Center in Berlin.”
“CityCenter represents a new paradigm of urban planning and design,” said Andy Cohen, FAIA, Managing Principal at Gensler Los Angeles, the executive architect for the entire project. “It reflects MGM Mirage’s sophisticated vision, and it has the critical mass to propel Las Vegas to another level.”
As executive architect of CityCenter, Gensler is responsible for providing project leadership for the entire 18-million-square-foot master plan and is teamed with MGM Mirage’s Design Group to coordinate and collaborate with residential developers, hotel operators, retailers and a group of world-class architects.
A local touch at ARIAWhile Gensler was the executive architect for CityCenter as a whole, Pelli Clarke Pelli Architects of New Haven, CT, designed the 4,004-room ARIA Resort & Casino, and this venue features some of the most prominent use of local stone. In order to achieve a standout experience for guests and patrons, the exterior features Meta-quartzite supplied by Las Vegas Rock of Jean, NV.
“For the use of stone in the overall design goal, we wanted to use a material that was very organic, touchable and reflected the area in Las Vegas,” said Peter Follett, AIA, RIBA, a Senior Associate of Pelli Clarke Pelli Architects.
Seeking the colors and tones of the surrounding Las Vegas environment, Follett and the design team were inspired by the surrounding hills of Nevada. Ultimately, they felt that local stone would be the material to reflect this setting most appropriately. “We had looked at some other materials,” said Follett. “Our real concern was to get a natural feel and the richness of stone. We keyed in on using stone, it was just a matter of finding the right stone.”
Meta-quartzite was selected for several reasons, including the proximity of Las Vegas Rock’s quarry, which is located outside of Goodsprings, NV. “Number one, they’re a local group - 40 minutes right outside of downtown Las Vegas,” said Follett. “Second, the color was right in line with what we were thinking and interested in achieving. And third, [Las Vegas Rock] was very willing to work with us and design what we wanted to achieve.”
Follett further explained that the client was very pleased with the selection. “They were very excited about the stone when they saw it,” he said. “They thought the figuring and color was just fantastic. They helped us choose the range and were interested in seeing the mock-ups we had. They were involved in quite a few of the steps.”
Pelli Clarke Pelli utilized the material on the exterior of the hotel’s spa, casino circle, one of the two main entries, a VIP drop-off and at the pool area.
Pieces used for the project vary in sizes, ranging from 9 x 12 inches to 96 x 60 inches, and they were processed over a 20-month timeframe, according to Jason Richardson, Production/Project Manager for Las Vegas Rock, who added that all cuts were made within a tolerance of 1 mm.
“What we tried to do was maximize slabs that were cut,” said Follett. “This is a LEED project, so we were very interested in utilizing [as much of the raw material as possible.]”
The spa tower features 2- x 5-foot modular panels of the Meta-quartzite with a honed face and a custom split-face accent band, according to Project Manager John M. Barrett of Carrara Marble Co. of America, Inc., which served as the stone installer.
Approximately 5,000 square feet of randomly placed 3-, 5- and 7-cm stone pieces make up the Harmon VIP entrance wall. “The mosaic pattern wall incorporates varying thicknesses and lengths of stone, creating a look like no other and welcomes the venues most distinguished guests,” said Barrett.
“Casino Square consists of nearly 2,500 square feet of stone, and is another unique area incorporating a ‘bullet’-shaped accent band and modular panels with stainless steel accents,” Barrett continued.
The installation of the stone called for a mechanical anchoring system that includes a 2 ½-inch extruded aluminum anchors with Dow Corning 756 building sealant to secure the stone. “This engineered veneer is comprised of many varying sizes of stone intricately manufactured and painstakingly installed to fit the large radius walls and cleanly appointed the lines that set the building apart on the Las Vegas skyline,” said Barrett.
Altogether, 70,000 square feet of honed Meta-quartzite was used for the exterior at the ARIA. “I think working with Las Vegas Rock and Carrara, and having the client involved with being able to go through the mock-up process, we were able to avoid any missteps streamlining the process,” said Follett. “The biggest challenge was picking the materials and finding its ranges, etc. The stone had this varied appearance, but as a whole, it creates this fantastic color.”
Other exterior use of stone can be found at the planters along the entrance ramps. The beds of these planters feature slate “Paddlestones” from Burlington Stone of England. These are from Burlington’s “secondary product division,” which utilizes what had previously been deemed waste material.
Pelli Clarke Pelli was present every two weeks during the installation to answer any questions or work with the contractor if needed. Opening day for the ARIA Hotel and Casino was December 16, 2009.
“The reaction has been extremely positive,” said Follett. “Everybody loves the stone. They love the color. I think the different uses of the stone - sometimes the mosaic look, the stacked look, the flat look and all of the different ways we used this stone - everybody was very happy with. We’ve gotten a lot of great feedback.”
ARIA's interior spacesThe interior use of stone at ARIA begins at the arrival lobby. In addition to meta-quartzite on the walls, natural stone was specified in a range of finishes for the floors, where a dark brown-hued stone was used. As guests approach the front desk, the floor takes on a geometric pattern of large-format textured and polished “planking” pieces, which were cut into rectangular pieces of varying sizes that appear to radiate out from the front desk. The change in texture also offers some variation in color, with the polished pieces carrying a darker appearance.
As the floor pattern progresses away from the front desk and towards areas such as the north entrance, other stone materials are integrated into the design, and they were specified in a range of colors - while also keeping some textured pieces in the mix. Additionally, textured stone pieces can be found on the walls away from the main desk, providing an extra level of contrast among the stone materials.
Meanwhile, some of the facility’s more sophisticated areas utilize stone in a more traditional, polished look. Offering 150,000 square feet of gaming, ARIA’s unique layout and design elements were designed to afford guests a more personal and intimate setting. For high-end players, exclusive salons offer high-limit slot and table games in private environments, and they were designed with premium building materials.
At the high-limit Baccarat gaming area, for example, a blend of white, rust and gold stone materials were used for the floor, and they were specified in a custom pattern that intertwines the various stones to create a one-of-a-kind floor pattern.
A different approach was taken for Jean Georges Steakhouse at ARIA, which was designed by the Dupoux Design team with a look inspired by “Roman amphitheater classicism.” The restaurant has a circular design that frames a “theatrical lounge” at the arena center, with five elevated platforms for the dining “audience” radiating outward. To create an atmosphere of “warmth and comfort” that also would not detract from the overall aesthetics of the restaurant, the design features a color scheme of black and ochre washed in amber ambient light. This includes the stone flooring, which features simple monochromatic tiles in a large format.
Of course, the spas at ARIA also feature a range of stonework, and some of the most impressive craftsmanship can be found at the Spa Suites. ARIA features three private spa suites, each serving as a personal “spa within a spa.” Each 800-square-foot suite includes luxurious amenities; a striking design complemented by serene “Aji stone” walls and natural light; a lounge area with entertainment offerings, vanity, lockers, a personal steam shower and a three-person hydrotherapy tub. The Aji stone was produced in Japan, where it was said to have been blessed to “inspire calmness and tranquility.”
Stone was also a component in linking ARIA to its counterparts at CityCenter. A sculptural courtyard by renowned hospitality designer Adam D. Tihany features marble-clad pyramids which were designed as a symbol of camaraderie between the various venues.
Vdara paves the wayThe first of CityCenter’s venues to open its doors was the Vdara Hotel & Spa, an all-suite boutique hotel, which also achieved LEED Gold certification. Adjacent to ARIA Resort & Casino and connected to Bellagio via a pedestrian walkway, Vdara offers direct access to CityCenter’s Tram.
Vdara’s exterior was designed by Rafael Vinoly of RV Architecture LLC in New York, while the interior planning, architecture and design was by BBG - BBGM’s New York office. “We are extremely proud to work with MGM Mirage and this world-class design and architecture team to create a sustainable urban center that seamlessly integrates a retail establishment with luxury residential living, hotel and casino,” stated Vinoly.
The design goal for the interior at Vdara was to create a residential flavor that merges East Coast sophistication with a relaxed West Coast lifestyle, according to Tony Machado, Senior Associate for BBG-BBGM.
Stone in various sizes, with the largest pieces being 24 x 36 inches, played a role in the design of the public spaces at Vdara. In the main lobby, the floors have a “pixilated” pattern using Lagos, Crèma Marfil and Light Emperador in a polished format. Meanwhile, the walls utilize a monolithic white limestone that was bush-hammered and grooved to give it a horizontal texture.
“The client was very involved and challenged us to provide an unusual layout in the lobby, but to not overcomplicate the installation requirements,” said Machado. “We presented over 10 various layouts patterns and combinations before the final pixilated concept was selected.
“We designed all the stone layouts as a giant puzzle, with each piece coded by number,” he continued. “There were four standard sizes of stone slabs. Because the lobby space follows the dramatic curving contour of the tower, there are two kinks that allow the modular layout to bend and follow the movement through the space. The thorough documentation helped minimize site supervision.”
The bush-hammered limestone at the lobby walls was the only area of challenge, according to Machado. “The stone was white and very porous,” he said. “Unfortunately, much of the stone discolored, leaving an unwanted pixilated pattern on the walls. The solution was to whitewash the stone, which created the monolithic texture that was the original intent.”
Light Emperador marble continues into the concierge lounge. “In the lobby and concierge lounge, the large-format stone flooring has added an expected quality and luxury, while the heavy textured stone on the wall has added depth and dimension,” said Machado.
The stone flooring also provides a muted backdrop for the space’s notable pieces of art. This includes a commissioned work by Peter Wegner, entitled “Day for Night, Night for Day,” which is comprised of two wall pieces made of stacked, colored paper, one solar-themed, composed of a range of yellows and oranges and soaring approximately 45 feet, and one lunar-themed, projecting a range of blues and reaching approximately 34 feet high. Also designed by Wegner, hanging lanterns act as a conversation starter between his solar and lunar pieces and provide soft light that cascades down into the lobby.
The suites at Vdara also feature upscale materials, including CaesarStone quartz surfacing, and this material was also specified for interior design elements within the Veer Towers and The Harmon at CityCenter.
Las Vegas' new landmarkWith ARIA and Vdara already receiving international attention, CityCenter is poised to be a project like none other in the world. Other facilities include Las Vegas’ first Mandarin Oriental; Veer Towers, the development’s only strictly residential buildings; and Crystals, a 500,000-square-foot retail and entertainment district.
In total, Vdara, Mandarin Oriental, Las Vegas and Veer Towers will include approximately 2,400 residences. Additionally, The Harmon, a 400-room luxury boutique hotel, is slated to open at CityCenter in late 2010. The complex will also feature a resident Cirque du Soleil production celebrating the musical legacy of Elvis Presley; and a Fine Art Collection with works by acclaimed artists, including Maya Lin, Jenny Holzer, Nancy Rubins, Claes Oldenburg and Coosje van Bruggen, among others. CityCenter is a design collaboration between MGM Mirage and eight internationally acclaimed architectural firms. In addition to Gensler, Pelli Clarke Pelli and RV Architecture LLC, these include Kohn Pedersen Fox, Helmut Jahn, Foster + Partners, Studio Daniel Libeskind and Rockwell Group. In addition to ARIA and Vdara being the first Las Vegas hotels to achieve LEED Gold certification by the U.S. Green Building Council, Crystals, Mandarin Oriental, Las Vegas and Veer Towers all have received LEED Gold certification by the U.S. Green Building Council. This marks the highest LEED achievement for any hotel, retail district or residential development in Las Vegas. The Harmon also is pursuing LEED certification.
