Marina Bay Sands | Safdie Architects

The Marina Bay Sands complex brings a taste of Las Vegas to Singapore. Three 55-story hotel towers are topped by a skypark that culminates in a 213-foot-long cantileverthe signature move in a 38-acre complex that also includes a casino, a retail complex, performance venues, a convention center, and a museum.

i’m not a big fan of the architect but it’s worth to know who were the big guns that made it happen.

The hotel tower atrium extends up to the 23rd floor, where the building narrows. The ground floor features lobby amenities and restaurants. Guest room circulation is accommodated by projecting balconies that look out over custom art installations.Image

and here is the Architect Magazine article by  Sara Hart:

Moshe Safdie, FAIA, is enjoying an embarrassment of riches. The architect’s Boston-area firm has five large-scale projects scheduled for completion this year—three in the U.S. and one each in Singapore and India. The Marina Bay Sands resort in Singapore, designed for the Las Vegas Sands Corp., is one of the most ambitious: The $5.7 billion, 9-million-square-foot program includes a 2,500-room hotel, convention center, casino, retail, dining, nightclubs, event plaza, and museum, all topped by the Sands SkyPark. The complexity of the program is behind the project’s eight-month-long grand opening: while the hotel and SkyPark opened last June, the final elements, including the ArtScience Museum, won’t open until Feb. 19.

Safdie confronted the project’s colossal scale by dividing the hotel component into three 55-story towers overlooking Marina Bay; the voids between them frame views to downtown Singapore. The sloping geometry of the towers required the structural engineers at Arup, particularly the bridge and tall-building specialists, to devise a strut-and-tension-cable system to support the walls during construction. “The struts were enormous, temporary steel legs, which crisscrossed the hotel atrium,” Safdie describes. “These were removed after large trusses linking the towers were installed” at the 23rd floor. The cables, not part of the original design, were left in place after the towers’ completion, and were grouted into the concrete shear walls to conceal them.

A low-rise, undulating podium in front of the towers houses a vast array of entertainment venues. But keeping the podium structures low meant that there was little open space left for outdoor amenities. “Once we laid the footprint of the building, we still lacked the necessary location for the amenities of the hotel complex, which includes swimming pools, gardens, and jogging paths,” Safdie explains.

To solve the problem, Safdie had the audacious idea to build the three-acre SkyPark, 656 feet in the air, by bridging the tops of all three towers. Though the park was originally constrained to the towers’ footprint, the design team decided, after consulting a feng shui expert, to cantilever a portion of the park off of the north tower. And it is no small cantilever: at 213 feet, it runs nearly the length of a 747 and is one of the largest public cantilevers in the world. “The move gave the building directionality, and now, as you enter Singapore from the highway, it presents itself as a dramatic gateway element,” Safdie says.

Tremendous structural and construction challenges followed, not the least of which involved extensive wind testing and modeling. Originally, the hull-shaped belly of the park was designed as a pure toroid, but the form was streamlined to allow for efficient cladding: 9,000 silver-painted, metal-composite panels enclose the mega trusses that bridge the three towers at the 55th story. Offices for hotel operations and mechanical rooms housing water tanks for the swimming pools are also contained within the hull.

The hull was built off-site in 14 separate steel segments. Each was trucked to the site, lifted into place using hydraulic strand jacks, and assembled on top of the towers. The two largest sections were a pair of 262-foot-long, 1,400-ton box girders that formed the 213-foot cantilever. At a lifting speed of 46 feet per hour, it took more than 16 hours to lift the girders and slide them into place.

At every step, the structural design of the cantilever was reevaluated and modified as necessary. The taper of the main supporting box girders was reduced to improve the cantilever’s response to vibrations that are created as people walk, run, or use the swimming pool. A 5-ton tuned mass damper located at the tip of the cantilever—and hidden within the hull of the architectural form—provides additional stability. The damper is suspended from transverse girders and accessed via catwalks in place for inspection and maintenance of the box girders.

It’s easy to get distracted by the mega-scale and complexity of the project, when looking at the numbers—billions of dollars, millions of square feet, and a skypark with a 15,000-square-foot infinity pool, and space for 3,900 people to mingle among 650 plants and 250 trees. Yet, Marina Bay Sands exhibits the same ingenuity and fearlessness that defined Safdie’s controversial Habitat 67 residential complex for the 1967 International and Universal Exposition in Montreal. The principles that drove that design more than 40 years ago remain the principles driving his work today: ethical standards, which require addressing the realities of urban density, demographics, and scale while preserving the genius loci of a place confronted by globalization. On the other hand, what most distinguishes the Marina Bay Sands as a Moshe Safdie design is his unflinching eagerness to push beyond perceived limits of construction to accomplish feats of derring-do.

Maximilian’s Schell | Benjamin Ball & Gaston Nogues

This vortex-shaped, temporary outdoor installation in the Los Angeles exhibition space of Materials & Applications, warped the flow of space with a featherweight rendition of a celestial black hole. Hovering over M&A’s courtyard,Maximilian’s Schell was a spectacle the size of an apartment building constructed in tinted Mylar resembling stained glass. The piece functioned as a shade structure, swirling overhead for the entire summer of 2005. The interior of this immersive experimental installation created a beckoning outdoor room for social interaction and contemplation by changing the space, color, and sound of the M&A courtyard gallery. During the day as the sun passed overhead, the canopy cast colored fractal light patterns onto the ground while a tranquil subsonic drone from the integrated ambient sound installation by composerJames Lumb entitled “Resonant Amplified Vortex Emitter” lightly rumbled below the feet of the viewer. When standing in the center or “singularity” of the piece and gazing upward, the visitor could see only infinite sky. In the evening when viewed from the exterior, the vortex glowed warmly while both obscuring and allowing glimpses of the building behind it. The assembly paid homage to a character played by actor Maximilian Schell in Disney Studio’s forgotten sci-fi adventure The Black Hole. Dr. Reinhardt is a visionary tyrant on a monomaniacal quest to harness the “power of the vortex” and possess “the great truth of the unknown.”

Ball Nogues invested more than a year into a development process that involved several prototypes, though actual fabrication took only two weeks. The result was an installation that functioned as not only architecture and sculpture but as a “made-to-order” product through a unified manufacturing strategy. The designers achieved their aesthetic effects by manipulating Mylar reinforced with bundled Nylon and Kevlar Fibers on a computer-controlled (CNC) cutting machine. Simultaneously reflective and transparent, the amber-colored film offered UV-resistance through a laminated golden metallic finish. The result was neither a tent-type membrane nor a cable net structure in the manner of Frei Otto, but a unique tensile matrix comprised of 504 different instances of a parametric component or “petal,” each cut and labeled using the CNC system. Every petal connected to its neighbors at three points using clear polycarbonate rivets to form the overall shape of a vortex. As though warped by the gravitational force of a black hole, the petals continually changed scale and proportion as they approached the singularity of the piece.

An integration of structure and skin, the vortex behaved as a “minimal surface”: prestressed, always in tension, yet definable mathematically. Its lineage is in the soap film surfaces modeled by Otto in the 1950s and ’60s; a process now typically accomplished using software that performs “finite element” calculations. After receiving hand sketches and computer models made by the designers, membrane engineer Dieter Strobel digitally crafted and refined the minimal surface model. He quickly and precisely manipulated it during the “form-finding” process while accounting for the distorting effects of gravity and enabling the finished vortex-shaped canopy to be in tension everywhere across its top surface. This gave it a pure and smooth appearance, especially when viewed from the exterior. Seen from the interior, the piece resembled an enormous transparent flower with its petals lightly draping and curling downward with gravity.
