The Wilshire Grand, a 73-story tower under construction in downtown Los Angeles, hasn’t yet risen out of the ground, but it’s already in the Guinness Book of World Records. That’s thanks to a February 15–16 event promoters called the Grand Pour, in which construction crews poured 21,200 cubic yards (82 million pounds) of concrete in 18 hours—the largest continuous concrete pour in history. Why all the fuss? The idea for the event originated with AC Martin's design itself. Unlike most of Los Angeles’ other high rises, the Wilshire Grand will be built around a concrete core rather than a steel frame. “As we worked through all of those things,...[AC Martin CEO Christopher Martin] realized this was going to be an absolutely huge technical event. It involves a lot of coordination and almost theater in terms of getting [the trucks in and out],” said design principal David Martin. “Then everybody really got behind that [and said], ‘let’s get a marching band and have a parade with the concrete.’” “There was really a buzz downtown about the whole thing,” added project manager Tammy Jow. The parade included 100 members of the USC marching band, representatives of the building’s owners, Korean Airlines, and, of course, the concrete trucks. “Whenever you have the Trojan marching band there you can’t go wrong, they’re all about the party,” said Jow. “What was really incredible [was that] as it got dark there were these huge spotlights, and it almost looked like a stage set,” said Martin. “So we were all having this huge party in the plaza next door, and these big trucks would go through the background.” The Grand Pour was only the beginning of the Wilshire Grand story. “I think what comes next is even more exciting,” said Jow. “Now that the mat is successfully in place we’re going to start seeing vertical.” At 1,100 feet in height, the $1.1 billion building is projected to be the tallest skyscraper west of the Mississippi River. Its office and hotel floors will be covered in floor-to-ceiling glass, another feature that sets it apart from its granite-clad neighbors. For the skyscraper’s crowning sail, as well as on portions of the east and west facades, AC Martin will use an ultra-clear, low-reflectivity glass. On the north and south sides, a radiant coating will boost performance and give the facade a more mirror-like aspect. The designers experimented with new coating technologies to ensure that hotel guests will be able to see out at night without glare from interior lights. The building’s other highlights include its unusual roofline, which was made possible by negotiations with the fire department regarding helipad requirements. “That allowed this building to be different, and hopefully will leave a legacy so that buildings can get back to being more interesting,” said Martin. The designers also worked to maximize the connection to the outdoors, and to tailor the mechanical systems to Los Angeles’ hospitable environment. Finally, the Wilshire Grand prioritizes urban design. “The lower parts of the building reach out and really embrace the city,” said Martin. “There’s a lot of ballrooms and big windows and terraces that reach out to the city.” For Jow, one of the best parts of working on the Wilshire Grand has been the people involved. “We were able to create a team in our office of fresh talent out of school, with skills some of us older people couldn’t dream of.” She pointed to the design of the tower podium, which was generated parametrically using Rhino and Grasshopper. The younger architects’ digital prowess meshed well with the older designers’ experience in construction, said Jow. “We’re able to work together and rationalize forms to make it affordable and buildable.”

The glass, stone, and metal exterior of the Hatfield-Dowlin Complex evokes the strength and agility of a college athlete.The superhero and the Samurai. That’s where Zimmer Gunsul Frasca Architects (ZGF) began their design of the Hatfield-Dowlin Complex at the University of Oregon. The football player, the architects imagined, is like Batman: stealthy and strong, he came to his powers not by supernatural accident, but through relentless training. At the same time, the athlete is a highly skilled warrior, the modern-day equivalent of Japanese military nobility. The facade of the new football training facility materializes these ideas in glass, stone, and metal. Dominated by horizontal expanses of tinted glass, it is powerful but not foreboding. ZGF offers the analogy to a suit of armor: the building’s skin balances protection and connection, solidity and agility. The most direct expression of the armor metaphor is on the Hatfield-Dowlin Complex’s west exterior. In Eugene, the real solar challenge comes not from the south, but from the west, where the sun hovers near the horizon for long periods all winter long. To minimize glare, the designers placed a floating sunscreen across the western face of the building. Using elevation studies and interior models, they determined the optimal placement of a series of tinted glass panels held in an aluminum frame developed by Benson Industries. The result is seemingly random arrangement of overlapping rectangles, which ZGF’s Bob Snyder likened to scales on a Samurai’s costume. On the other three sides of the building, ZGF installed a curtain wall of fritted, triple-pane insulated glass units supplied by SYP. The frit pattern was inspired by the nearby John E. Jacqua Academic Center for Student Athletes, which ZGF also designed. The Jacqua’s facade comprises two layers of glass, five feet apart with a stainless steel wire screen in between. At the Hatfield-Dowlin Complex, the designers achieved a similar texture on a single layer of glass. “We saw that as a microcosm of the five-foot wall [at Jacqua],” said Snyder. The frit pattern was developed to be visible from both outside and inside the building, and to suggest movement as one passes along the facade. The final components of the Hatfield-Dowlin Complex exterior are stone and metal cladding. ZGF chose granite and basalt from Western Tile & Marble, which was treated with water jets for a striated texture. The designers used stone primarily on the first three floors of the building. “We established that as the stone zone, we wanted the weight of that material, the high durability of that material down low where folks would come into contact [with it],” said Snyder. Above, the stone transitions to aluminum panels for a lighter feel. “We worked with [Streimer Sheet Metal Works] to get the tightest radius we could get on the ribs of the metal panel,” explained Snyder. “We really struggled with that material [to make it] as fine as the stone, so it didn’t look like you were wearing tennis shoes with your tuxedo.” Plate-steel fins at the mouth of the parking garage and near the entrance sidewalk suggest the hard back of a dinosaur—yet another reference to armor. For Snyder, the combination of materials on the building’s facade achieve a balance between groundedness and ambition. Like the athletes inside it, the Hatfield-Dowlin Complex remains tied to the earth even as it appears to float above it. “The idea is that to be really good at football, you need to be right on the edge,” said Snyder.
As the buzzword "transparency" gains greater meaning in product specification, glass is an energy-saving, sustainable, and aesthetically pleasing option. Strand 3form 3form’s Pressed Glass is newly available in the Strand pattern (above), a compressed interlayer of fine gauge threads in three monochromatic colorways. It can be further customized through color matching, etching, and fritting options. Available in widths as large as 48 inches and lengths of 120 inches, it can be specified in either a 5/16-inch or 1 5/16-inch gauge thickness. Its inherent strength meets ANSI Z97.1 standards. DF-PA Dichroic Film 3M Architectural Markets 3M’s Dichroic films can be applied to any smooth surface with a pressure sensitive adhesive; the DF-PA is recommended for glass applications. Two color values—Chill and Blaze—span color ranges from blue to magenta to gold, in either a fully covered opacity, or as a decorative graphic. Durability complies with interior and exterior use, and the film can be easily removed from architectural screens, window fronts, curtain walls, or glazing when it is time for an update. Railings and Floors CARVART This structural laminated glass can be safely specified for floors and railings. Flooring can be installed as a freestanding finish or incorporated into another system with specially engineered mounting hardware, and stair treads can appear to “float” or integrate into stringers. For railings, top and side mounting options can be affixed to most structures, or can be suspended from coordinating adjustable point fittings. Railing caps are available in round, oval, or square profiles. Alice General Glass Digital printing directly to glass provides customization options as broad as the imagination of the architect or designer. Bespoke patterns or imagery can be specified, in addition to a selection of bright and monochromatic colors and patterns for glazing, curtain walls, or interior applications. Fully opaque backing is also available, enhancing the contrast and crispness of any printed design. SunGuard Super Neutral 68 Triple Glaze Guardian Industries Guardian SunGuard SuperNeutral 68 glazing offers improved solar control and abundant natural light. The Valley View project shown here uses SunGuard SN 68 triple glaze, providing a visible light transmission of 52 percent and a solar heat gain coefficient of 0.32. SunGuard SN 68 can also be laminated for noise reduction and hurricane protection. KnollTextiles Glass Collection Skyline Design Seven designs from KnollTextiles are rendered on glass through two production techniques: Eco-etch achieves varying levels of opacity, and AST Digital Glass Printing introduces color to partial transparency. These options provide for customization of classic patterns like Divine and Enchantment, designed by Dorothy Cosonas, or the mid-century Cyclone and Fibra, designed by Eszter Haraszty. Liquidkristal Lasvit Designed by Ross Lovegrove, Liquidkristal was inspired by dynamic forms found in nature. The design was first modeled digitally to simulate thermo induction, which can imbue the qualities of water to glass under very high temperatures. A large-scale mold system was formed from the study’s results, to produce multiple pattern variations over multiple sheets. In addition to interior applications, Liquidkristal is also suitable for glazing and facades. Olivia Joel Berman Glass Studios The circular, three-dimensional pattern of Olivia is enhanced with subtle reflectivity to inflect motion into any space. Back painting options are available in a range of colors on panels measuring 53 by 108 inches. Produced for interior applications, it can be tempered for safety and impact resistance on exteriors as well. ClearShade Glazing Unit Panelite A honeycomb-like insert fits between two sheets of glass and redirects up to 70 percent of natural light, reducing solar glare and heat gain for midday-SHGC measurements as low as 0.11. The cellular configuration is made from a durable but transparent polymer that is resistant to UV rays. The product’s bi-directional scattering distribution capabilities are compatible with Radiance, Energy Plus, and SketchUp modeling programs. Sungate 600 PPG This double-glazed insulated glass unit boasts an efficient configuration tailored to the region of application. In climates where heat gain is optimal, coating on the Number 3 surface blocks heat loss for a U-value of 0.33, while maintaining a 0.65 SHGC and visible light transmittance of 71 percent. For higher insulation values, the Sungate 600 coating can be placed on the Number 4 surface when combined with a solar control low-e glass, for a net gain in U-value of 20 percent. SageGlass Simplicity Sage Electrochromics This electronically tintable glazing is available in a solar-powered, wireless format. In lieu of low-voltage wired connections, a strip of solar photovoltaics interfaces with a low-profile electronic controller and battery pack that can provide power for up to two days without a charge. The wireless system also configures with light and building management programs from Siemens, Lutron, Schneider, and Johnson Controls. Bistro Green Vetrazzo Vetrazzo, the recycled glass division of Polycor, has been diverting glass from the waste stream since 1996. The surfacing material uses consumer beverage containers, waste from glass manufacturers, building demolition, traffic light lenses, windshields, shower doors, and more. It takes nearly 1,000 bottles to make one 5- by 9-foot panel that is 85 percent glass by volume and bound with Portland Cement. Sixteen of Vetrazzo’s product lines are Cradle to Cradle certified. Dynamic Glass View Glass Insulated glass units as large as 5 feet by 10 feet feature programmable electrochromic levels of 60, 40, 20, and 4 percent tinting with user controls from a smart device app to reduce heating and cooling loads, electric lighting, and solar glare. An intelligent setting can be programmed for sensory occupancy to optimize energy usage as well as user comfort. All four tint levels can be achieved in one unit, with adjustment times akin to the passing of a cloud overhead.

Earlier this year, AN assembled a list of the most prominent projects rising in Miami. One of the developments, the Herzog & de Meuron–designed Pérez Art Museum (PAMM, formerly the Miami Art Museum), is nearing completion and is scheduled to open to the public by the end of the year. At The Architects Forum Glass+Performance on September 11th in Atlanta, key participants, including Peter Arbour of seele, Vinu Abraham of Architectural Testing, and Emil Hoogendoorn of John Moriarty & Associates will present on the ambitious design and construction process of the Miami Art Museum facade, calling the endeavor The Biggest Glass in Miami Dade County. Positioned on Museum Park overlooking Biscayne Bay, upon what has been declared the Magic City’s “last big piece of public land downtown,” the new museum’s concrete and glass structure gestures to Stiltsville, a vernacular 1930s form of architecture built on the bay. Various column-free exhibition galleries within the 200,000-square-foot, three-story building accommodate works of differing scales. The museum contains an educational complex, auditorium, and digital workspaces, along with a restaurant and store. Shaded by a canopy, the museum is situated on an elevated plinth open to a landscaped veranda and plazas. The Architects Forum is hosting a session at GlassBuild America filled with short presentations of the design, prototype testing, and construction of the museum's state-of-the-art facade. Arbour, Abraham, and Hoogendoorn will explain the multifaceted and impressive process, focusing on the use of glass as a facade material. A panel discussion and audience Q+A will take place after the presentation. Register to learn about the process behind the Pérez Art Museum's glass facades and discover more information about Session 3: The Biggest Glass in Miami Dade County: Construction of the Miami Art Museum Facades.
Glass-clad, cable-net structures are one of today's leading forms of high-transparency facade technology. Since 2009, Enclos has been an authority in the design, engineering, fabrication, and assembly of custom curtain wall systems and structural glass facades. The company has published a number of reports about building skin systems. Volume 1: Skylights of the Facade TecNotes Series focuses on glass in overhead applications and the unique opportunities it brings. On September 11th, Enclos’ Mic Patterson will join AN to discuss glass facades at GlassBuild America: The Architects Forum in Atlanta. Mr. Patterson will share several examples that show how optimal transparency and aesthetic elegance can work together. He will discuss projects such as 51 Louisiana in Washington, D.C., two existing buildings that have been joined by a glass-clad atrium, and Station Place: Security & Exchange Commission Headquarters, also in Washington, D.C., which consists of a 55-foot-long and 60-foot-wide skylight. Mr. Patterson has lectured internationally on various aspects of advanced facade technology and is the author of Structural Glass Facades and Enclosures.
