Last month, Metals in Construction magazine and the Steel Institute of New York gathered at TheTimesCenter in New York City to announce the winner and five finalists for their 2019 Design Challenge, titled “Create A New Urban Pathway.” The competition asked architects, planners, and engineers to design a pedestrian bridge that connects the forthcoming Moynihan Train Hall, situated across Eighth Avenue from Penn Station, with Chelsea’s Hudson Yards, the city’s largest private real estate development, the first phase of which opens this week. The pathway between the Moynihan Train Hall and Hudson Yards would serve as an anchor for the rising development of Manhattan’s Far West Side, which is expected to receive roughly 100,000 pedestrians traveling between the two destinations each day. With midtown’s upcoming surge of foot traffic, the design challenge sought to think of ways to make pedestrian travel more safe, efficient, and appealing to city dwellers, particularly through the construction of floating promenades—elevated, landscaped walkways that not only reduce inner-city congestion, but also prove beneficial to the health and overall well-being of citizens. Judges and participants of the competition looked for inspiration from the immensely popular High Line—the now iconic urban pathway that, in 2014, dramatically transformed from an abandoned railway into a picturesque walkway. Metals in Construction magazine awarded a $15,000 grand prize to the winning team from New York–based DXA Studio. The team’s proposal, titled “The Midtown Viaduct,” was chosen from a group of 45 qualifying entries and was praised by the panel of four judges for its structural practicality and streamlined design, which would offer city dwellers a new and exciting urban experience. The Midtown Viaduct is composed of interlaced steel plate work, drawing from the industrial components of the High Line and the steel of the original Penn Station, to create a winding and dynamic walkway that would connect the two destinations and give pedestrians a recreational space to stride. “[The Midtown Viaduct] employs forward-thinking approaches to form, fabrication, assembly, and urban solutions that mitigate/synthesize the complex forces of contemporary cities,” wrote the team from DXA Studio. While DXA studio's pedestrian bridge will probably never materialize in real life, the proposal serves as an innovative approach to topics concerning the livability and walkability of cities. Metals in Construction magazine will be holding another design competition next year, themed “Create A New Urban Identity,” which will challenge participants to reimagine the skin of an existing building in New York City. More details about the competition will be announced in September 2019.

Over the last decade, the renewable energy industry has boomed due to the proliferation of new technology that is reducing the cost of construction and long-term operability. However, one critical problem still remains: storing renewable energy during lulls in wind speed or sun exposure is often prohibitively expensive. In response to this issue, Energy Vault, a subsidiary of California’s IdeaLab, has recently announced a straightforward mechanism for the conservation of renewable sources using kinetic forces. The mechanism proposed by Energy Vault is a nearly 400-foot tall, six-armed steel crane. Using proprietary software, the towering structure orchestrates the placement of 35-ton blocks of concrete in response to drop-offs in demand and fluctuations in environmental conditions. How does it work? As power demand decreases, the cranes surround themselves with concentric rings of the concrete bricks lifted by the leftover power from surrounding wind and solar farms. Once demand increases, the cranes begin lowering the bricks, which powers turbines that transform the kinetic energy into electricity that gets pumped back into the grid. Energy Vault’s team looked toward preexisting renewable energy sources that rely on gravitational forces. According to Energy Vault, the technology was influenced by energy retention strategies of hydroelectric power dams that pump water into a series of cisterns on higher ground that ultimately flow downwards into energy turbines once demand rises. Unlike conventional resources used for the retention of renewable energy, such as Tesla’s Powerwall and Powerpack lithium-ion stationary batteries, the system developed by Energy Vault does not rely on chemical storage solutions or high-cost materials. Recycled debris from preexisting construction sites can be used for the fabrication of the bricks, which are viable for up to four decades without a decrease in storage capacity. Currently, Energy Vault is partnering with India’s Tata Power Company Limited to construct an initial 35 MWh system with an expected date of completion in 2019.
Brought to you with support fromIn 2011, Buenos Aires-based estudio Claudio Vekstein_Opera Publica (eCV) was approached by the government of Argentina's Sante Fe Province to design a space memorializing the centennial of the Alcorta Farmers Revolt. Founded in 1892, Alcorta is a small farming town laid out according to a dense and rigid grid surrounded by plotted agricultural land, an urban morphology typical of this southern corner of the province. From this historical context, eCV's Memorial Space and Monument of the Alcorta Farmers Revolt rises as an asymmetrical fissured edifice wrapped with semi-translucent, prefabricated epoxy resin-and-fiberglass panels.
fiberglass, and rough burlap cloth. For the relief of the bags, eCV designed a set of rectangular molds of a standard height and varying widths. These modules are plugged into 275 alternating facade elements measuring approximately 3.5 feet in height and 7 feet in width. The billowing mass of the reinforced resin panels is broken by a series of narrow apertures of four different dimensions. The structure of the monument is highly visible, consisting of exposed and inclined steel beams and trusses planted into a concrete foundation. Mounting the precast facade panels onto the structure was a fairly straightforward operation: the panels are attached to a bracket-connected metal framing system with self-tapping screws. In total, the installation of the panels took approximately three weeks. A significant portion of the northwestern facade folds over the 4,300 square-foot built area and interior segments of the panels are backed by rows of grooved fiberglass. The rear elevations, which host offices of the Agrarian Federation and communal spaces, are fronted by rectangular corrugated sheets of metal that are similarly fastened to a framing system. During the day, the semi-translucent screen filters a soft yellow light into the memorial's principal spaces. The rough burlap fabric, which provides the panels their outward dark hue, takes on the form of a glowing and sinuous skin. As the sun sets and interior spaces are illuminated by artificial lighting, the facade becomes a lamp beaming toward Alcorta. Beyond the facade, eCV’s interior is spartan and reflective of the populist ethos of the overall design typology–the flooring is bare concrete, with steel trusses and cross braces cascading below the slanted roofline. After six years of episodic construction, the complex opened to the public on the 106th anniversary of the uprising in June 2018.The complex, located on an approximately 81,000 square-foot plot, is a visual homage to the town and region’s proud pastoral heritage. For the main northwestern facade, eCV Principal Claudio Vekstein turned to the region’s traditional forms; during the harvest season, farmers would pile their corn bags into hillock-scale mounds as a testament of collective pride in their work. Approaching the memorial from the southern border of the town, Vekstein achieves a material and symbolic bridge to the past with a vast canvas of an “insistent, alternating and syncopated relief of bags” formed out of epoxy resin,
Brought to you with support fromIn 2011, Dominique Perrault Architecture (DPA) was chosen by France Galop, the governing body of horse racing in France, to redesign and modernize Paris’s venerable Longchamp Racecourse. Located in the city’s second largest park, Bois de Boulogne, the design of the 160,000-square-foot project seeks to connect to the surrounding landscape—the racecourse’s most prestigious events occur during the fall—with a luminous gold-yellow aluminum and steel facade. Construction of the project was completed in January 2018.
concrete pavilions that dwarfed their surroundings. DPA's update stripped away these bare concrete additions, built a new 10,000-person capacity grandstand, and restored surrounding historic structures, with the goal of boosting year-round use of the facility and its overall cohesion with the surrounding city. The new 525-foot-long grandstand has a polished golden hue, which contrasts with the bright white coloring of adjacent historic structures. Aluminum and steel in a variety of treatments and configurations clad a steel and concrete structural system. For the curtain wall, DPA opted for sliding, 10-foot tall stainless steel mesh panels stretched within a frame by a simple pin and rod mechanism. Produced by metal fabrics manufacturer GKD and framed by LCD Pose, the operable panels are a subtle kinetic element that facilitates natural ventilation and light filtration. An aluminum rainscreen, produced and installed by Bysteel, courses across the complex in flat rectangular panels to create a protruding chevron frieze. Below the cantilevered top balcony, the iridescent cladding serves as a semi-reflective soffit that distorts the scene below. Glass panels, measuring approximately six feet in width and four feet in height, line the grandstand as a semi-translucent balustrade. To ensure visibility of the racetrack for the audience, glass manufacturer and glaze specialist Saint Gobain provided low-iron SGG Diamant panels, facilitating greater light transmittance and minimal green tint. The panels were screen printed with pixelated patterns evoking foliage across the facade. The massing of the grandstand is meant to represent the motion of a galloping horse: the top floor dramatically cantilevers 65 feet over a steel-and-concrete console and inclines toward the adjacent racecourse. With open-ended terraces—referred to as "transparent shelves" by DPA—and a design that faces outward, the crowd is afforded vistas of the stables below and the city beyond.Opened to the public in 1857 as part of Haussmann’s civic improvement schemes, the Longchamp Racecourse has undergone significant transformations over the course of its century-and-a-half existence, including the destruction of two historic grandstands in favor of mid-century
Brought to you with support fromEstonia-based architectural practice molumba has enlivened a suburban office block with a unique concrete and aluminum screen assembly. The project was commissioned by AS Elering—the nation’s largest transmission systems operator for electricity and natural gas—as a dramatic, three-fold expansion of the preexisting structure in Mustamäe, a southwestern neighborhood in the nation’s capital of Tallinn.
aluminum strips measuring 12 to 41 feet, which are in turn welded to a series of connecting bars. Each pier possesses its own steel support structure consisting of two internal, vertical columns fastened to the welded connecting bars. The design of the complex references the spindly and bundled power line, a ubiquitous feature across urban landscapes. AS Elering operates a multi-acre electrical substation next door. According to design lead Karli Luik, molumba envisioned the project as “the brain of the electricity and gas transmission network, monitoring and administrating their vitally important circulation.” As a vitally important aspect of Estonia’s energy infrastructure, the entire 40,000 square-foot complex is ringed by a perimeter wall fashioned of the same turquoise aluminum screen. For molumba, the bigger question was how to give the mesh triangles a truly functional quality outside of their aesthetic elements. The two planes of the piers form an acute isosceles triangle: the two congruent sides measure just under four feet while the base is approximately three feet. This shorter edge is placed atop the building’s 20 by 10 foot black precast concrete panels and wedged between window openings. With a 41-degree circumcenter angle, the piers function as effective passive sun shades for office functions within. Additionally, the mesh frame serves as an industrially-produced lattice screen for future vegetative growth to coil up the facade. The interior, designed by Stuudio Oü, features a design that similarly echoes the building's utilitarian function. Spiraling stairwells, built of concrete and steel, vertically course through the east and west elevations of the headquarters, while exposed pipes, cables, and pendant lamps made of recycled insulators line the ceiling and walls. A central vegetated courtyard and a two-story, wood-paneled stairwell, with steps of varying size, are the office block's principal communal areas. At the core of it all lies the "Brain," where the nation's energy transmission network is surveilled through a hippodrome of monitors.Over 140 turquoise mesh piers ring and visually buttress each elevation, a play on historical castellation and Gothic design found throughout Tallinn’s Old Town. The piers are built of full-length
Brought to you with support fromCompleted in June 2018, the Palace for Mexican Music is a bold intervention in the heart of historic Mérida, Mexico, that establishes a relationship with the surrounding century-old architectural milieu through lightly detailed limestone and dramatic matte-black steel ribs. The design team consisted of four local practices: Alejandro Medina Arquitectura, Reyes Ríos + Larraín arquitectos, Muñoz Arquitectos, and Quesnel Arquitectos.
Mayan structures. Seen from above, the nearly 100,000-square-foot Palace for Mexican Music is organized around a U-shaped courtyard, called the “Patio of Strings,” which faces the rear elevation of the four-century-old Church of the Third Order. A series of newly constructed alleyways rhythmically break the solid stone mass to provide routes of entry between the courtyard and the complex’s library, museum, and concert halls. Mayabtun Marmoles, a local stone supplier, harvested local Yucatán limestone, referred to as Crema Maya or Macedonia Limestone, for the project’s cladding and flooring. The panels, measuring 4 feet by 1.5 feet, are embellished with a polished or hammered finish. Each panel is fastened to the complex’s steel frame with aluminum holding brackets produced by Sistema Masa While the use of local building material is a direct visual nod to the physical character of the Centro Historico, the design team went a step further with the facades' stone and fenestration pattern. The vertical bands of stone are meant to serve as notational bars while the glass panels are notes from the popular Yucatan folk song, Esta Tarde Vi Llover. The 444 matte-black steel ribs are the defining element of the north elevation and courtyard. In both areas, the 30-foot hollow-steel ribs are fastened to an exterior rail that is in turn soldered to a series of corbels that protrude from the floor plates. Corridors within the courtyard are semi-open to the elements, wrapped by a glass balcony and sheltered by the stone-clad steel frame. To shield this area from sunlight, the steel ribs break into two planes, one vertical, the other slanted. For the four-firm team, the design of the Palace for Mexican Music is an attempt to "establish a new precedent for a public building to contribute to the revitalization of its surrounding space" through the use of contextual contemporary design and accessible public space. After a rigorous research and design process, their final execution has achieved that goal.The provincial capital of Mérida is located on the northern edge of the Yucatán Peninsula, a region noted for its distinct Mayan culture, and nearly two-thirds of the city’s population is indigenous. Mérida’s Spanish core consists of a broad range of colonial architecture built of locally sourced limestone, much of it ripped from
Less than two weeks after President Trump signed sweeping 25 percent steel tariffs and 10 percent aluminum tariffs into law, the construction industry is already smarting, according to a report by National Real Estate Investor. Although the tariffs exclude steel coming from Canada and Mexico (at the time of writing), interviews with developers and those in the construction industry suggest that some projects are already seeing steel increase in cost by up to 10 percent. The culprit is speculation about price increases six to twelve months down the line, after the full impact of the tariffs make themselves felt. The panic isn’t without precedent. A 21 percent tariff imposed on imported Canadian timber in November of last year, used in 25 percent of wood-framed projects in the U.S., led to a nationwide rise in construction costs for single and mid-family homes. Contractors were forced to raise their prices, cut back on their use of timber, switch to steel, or change the design of their homes to use less materials. Joe Pecoraro, a project executive at Chicago-based general contractor Skender, told National Real Estate Investor that a client developing affordable housing might be forced to delay their project if steel costs rose any further. “Uncertainty drives people to be very conservative, risk-averse. It is affecting our deals,” said Pecoraro. Ironically, domestic steel fabricators may be hit harder than international firms as a result of the tariffs only targeting raw steel. With costs rising for their raw materials, Engineering News Record has reported that some domestic fabricators have already lost jobs to competitors based in Canada and Mexico. 1.2 million tons of fabricated steel was produced in the U.S. with imported materials in 2017, which went towards building bridges, roads and buildings. Two days before President Trump signed the tariff order, the AIA had released a statement warning that rising material costs would lead to decreased project budgets and potentially stifle architectural innovation. It remains to be seen how the tariffs will affect the country’s building boom in the long term, but those in the steel industry are still onboard.
New tariffs on steel and aluminum proposed by President Donald Trump will have negative effects on the American design and construction industries, American Institute of Architects (AIA) leadership has said in a statement. The Trump administration's plan would impose tariffs of 25 percent on steel and 10 percent on aluminum, something that experts say will have wide ranging effects on both trade and the domestic economy. And while the issue is being hotly debated on the national and international stage, the AIA is weighing in with a striking warning that a rise in material costs could mean major losses for the U.S. economy. "The Administration’s announcement of new tariffs on steel and aluminum imports threatens to drastically increase the prices of many building materials specified by architects. These metal products are some of the largest material inputs in the construction of buildings. Structural metal beams, window frames, mechanical systems and exterior cladding are largely derived from these important metals," AIA President Carl Elefante, FAIA, and EVP/Chief Executive Officer Robert Ivy, FAIA, said in a statement in response to the proposed tariffs. “As creative problem solvers, architects rely on a variety of these materials to achieve functional and performance goals for their clients. Inflating the cost of materials will limit the range of options they can use while adhering to budgetary constraints for a building," they said. "By the same token, the Administration’s proposed infrastructure funding will not achieve the same value if critical materials become more expensive. Furthermore, the potential for a trade war risks other building materials and products. Any move that increases building costs will jeopardize domestic design and the construction industry, which is responsible for billions in U.S. Gross Domestic Product, economic growth, and job creation.”
London’s Frieze Art Fair opens a second pavilion by Universal Design Studio after successful 2014 show
The Frieze Art Fair looks to capitalize on the 55,000 people who thronged a pavilion by Universal Design Studio (UDS) last year by commissioning another. The five-day festival is held in Regent’s Park, London every October. Starting in 2003, Frieze London has quickly grown to become one of the world’s foremost art fairs. A New York outpost began in 2012, held each May on Randall’s Island, Manhattan. For the 2015 pavilion, UDS has used the main construction components of Frieze—membrane, steel, board, and aluminum—to create an appropriate temporary structure. New to the fair this year is a Reading Room which offers a diverse selection of art publications and hosts live events. To entice people into the space, Frieze has collaborated with Petersham Nurseries Restaurant for a pop-up cafe and bar on the mezzanine level overlooking the fair. Aside from the gallery spaces, the design team has sought to give these areas purpose and identity, bringing the park into the surrounding vicinity. This was achieved with the help of careful planting by Hattie Fox of Shoreditch-based That Flower Shop. Clever uses of visual framing emphasize views and encourage people walking through the fair to enter various spaces. “We were keen to find ways of bringing the park into the Fair," Jason Holley, a director at UDS, said in a statement. "We achieved this by creating an entrance experience which is in dialogue with the tree canopy, framing and drawing attention to the transition between the Park and Frieze, and through the creation of windows within the restaurant areas that offer glimpses into the park. We are also incorporating planters throughout the Fair which are carefully curated arrangements of plants that directly reference the type of planting found in the park.” “Much of our focus in this respect has been on creating a logical flow around the Fair, with widened aisles, connections and turning points – punctuating the journey with the formation of pause points – moments of change," Hanna Carter-Owers, director at UDS, said in a statement. "The galleries are doing a huge volume of business at the Fair and there needs to be consideration to how people and galleries work within the space.”
Perforated steel and translucent glass balance privacy and pop.For their Center for Manufacturing Innovation (CMI) in Monterrey, Mexico, Metalsa, a global manufacturing firm that specializes in automobile and truck chassis, did not want just another factory. Rather, the laboratory and testing facility, located in a state-sponsored research park adjacent to the Monterrey airport, was to be a "showpiece," explained Brooks + Scarpa Architects principal Lawrence Scarpa, "not just for their clients but from a work environment point of view, and a sustainability point of view." Despite the many challenges inherent to building across the United States-Mexico border, the Los Angeles architects succeeded in delivering a LEED Platinum design wrapped in a striking double skin of translucent glass and perforated steel panels. The facility's uneven sawtooth profile is the product of both historical and contextual references. "They are an industrial company, and I always loved the old warehouses with the north-facing clerestories, designed back when there was no electric lighting," recalled Scarpa. "That was what I was thinking about before I even went to the site." His first visit to Monterrey confirmed his instinct. "The mountains there are really sharp and jagged like that—it was an immediate concept for the building," said Scarpa. Like their 19th-century antecedents, moreover, the clerestories provide daylight and allow hot air to accumulate high above the inhabited spaces, thus reducing reliance on artificial lighting and cooling. The resulting form had one major drawback, however. "The issue we were faced with was that the primary way you enter the building is from the west, so we would have a broad face in the worst possible thermal position," said Scarpa. To solve the problem of solar gain without sacrificing the sawtooth roofline, Brooks + Scarpa implemented a double skin with an outer layer composed of perforated steel panels. With a wraparound sunscreen in place, explained Scarpa, "we could have a translucent skin behind it, but could modulate light and heat gain." Several factors influenced the perforation pattern on the outer skin. It began as an abstraction of Metalsa's corporate identity, said Scarpa, but evolved to respond to programmatic requirements. Perforations of different sizes and densities reflect the need for more or less privacy. Areas related to proprietary research and development are more opaque, while the office spaces cantilevered over the transparent northwest entrance benefit from the additional daylighting allowed by broader perforations. CMI's translucent inner skin of fluted glass refracts light, preventing glare from interfering with computer-based work. To prevent the occupants from feeling trapped in a windowless box, the architects carefully modulated the distance between the envelope's two layers. "When you're on the interior, it doesn't just look like a blank wall," said Scarpa. "When you're on the inside, you can't see through it, but you can see shadows move on the translucent surface." Designing for an out-of-country client is bound to produce hiccups, and the Metalsa project was no exception. For instance, Brooks + Scarpa had initially imagined that the auto giants would fabricate the perforated metal skin in-house, but turned to another supplier when disrupting the company's manufacturing flow proved cost-prohibitive. The architects nevertheless made the best of the situation, streamlining their vision to fit the situation at hand. "The technology that was available to us in Mexico is not overly sophisticated, so from the get-go we decided to take a more simplistic approach, utilizing a multi-layered skin," said Scarpa. "It was easy to construct, and it's not difficult to understand."
Navy Pier’s new “Wave Wall” by nArchitects lays a modern Spanish Steps at the foot of a Ferris wheel
Navy Pier is three years into a $278 million overhaul, and the new face of Illinois' most visited tourist attraction is beginning to emerge—most recently a grand staircase titled “Wave Wall" washed over the foot of the pier's famous ferris wheel. The peninsular mall and mixed-use amusement park has many major changes still in store, courtesy of a design team led by James Corner Field Operations. But photos available on the website of designers nARCHITECTS reveal a completed portion of the project collectively called “Pierscape” that creates an outdoor amphitheater from a simple stairway. (The full design team includes dozens of consultants.) The form of the new public space, which faces south into Chicago Harbor, resembles a sweeping wave or a wending draft of wind. Treads made of composite materials domesticate the snarling steel risers. Glass beneath the steps allow passersby indoors at the Pier to glimpse activity on the steps outside. From the bottom of the stairs, the project unspools into an audience seating area for public performances, and also frames the historic Navy Pier Ferris wheel—a 196-foot tall wheel will soon replace the current one, itself a stand-in for the 264-foot icon first transported to the spot from the 1893 World's Columbian Exposition. The designers say “Wave Wall” was inspired by the Spanish Steps in Rome.
Virginia Tech students demonstrate a light touch with glass and steel pavilion.The undergraduate architecture students enrolled in Virginia Tech's design/buildLAB begin each academic year with an ambitious goal: to bring a community service project from concept through completion by the end of the spring semester. In addition to the usual budget and time constraints, the 15 students taking part in the course during the 2013-2014 school year faced an additional challenge. Their project, a public pavilion for Clifton Forge Little League in the tiny hamlet of Sharon, Virginia, was entirely lacking in contextual cues. "It was interesting because our previous design-build projects have been downtown, with lots of context," said Keith Zawistowski, who co-founded and co-directs design/buildLAB with his wife, Marie. "Instead, we had a pristine, grassy field with a view of the mountains. We joke that this is our first group of minimalists." The students' understated solution—three geometric volumes unified by the consistent use of a vertical sunscreen—turns the focus back to the pavilion's surroundings with a restrained material palette of concrete, glass, and steel. Design/buildLAB assigned a separate structure to each element of the Sharon Fieldhouse program, nestling the open-air public pavilion between glass boxes containing the restrooms and concessions kitchen. Different roof heights distinguish the spaces, yet a common material vocabulary and their arrangement along a single horizontal axis allows them to be read as a single object. "The students describe the field house as a linear incision through the site," said Zawistowski. "Basically it's just light cut through the green landscape." Because Sharon Fieldhouse is intended for seasonal use, the students focused on maximizing environmental performance for the warmer months of the year. "Everything's about cooling and ventilation," said Zawistowski. A no-energy ceiling fan cools the kitchen, and tempered laminated white glass helps cut solar gain inside the enclosed areas. "The glass has a translucent quality, so that the spaces are bathed in even light, eliminating the need for electrical lights during the day," explained Zawistowski. The external sunshade, comprising vertical steel plate elements painted white, serves both conceptual and practical ends. "The shade screen is about intimacy and privacy—not just under the open-air pavilion but in the enclosed spaces," said Zawistowski. "The elements vary in density. They're tighter together toward the more private parts of the building." At the same time, larger gaps between the screen's members on the east side of the pavilion welcome in the morning sun, while to the west the steel bars draw together to provide afternoon shade. The screen simultaneously functions as skin and structure. "In most cases, the sunshade is tacked on. In this case it's part and parcel of the architecture," observed Zawistowski. Wider steel bars take the weight of the building's roof, and help conceal downspouts. "Everything is hidden there in the screen," said Zawistowski. "We brought a new group of students to the field house and asked them if they could figure out how rainwater could get off the roof. They didn't know." The students prefabricated portions of the pavilion at Virginia Tech's Blacksburg campus, panelizing the screen members and roofing. "One thing that bothers us in design-build education is that multiple generations tend to work on one project," said Zawistowski. "It's important for us that the same group sees the implications of what they design, so we rely really heavily on prefabrication." On campus, he added, students are able to take full advantage of the university's resources. Once on site in Sharon, the students completed assembly in just a couple of weeks. Given the fact that his students conceived of, fundraised for, programmed, planned, designed, and built Sharon Fieldhouse in less than ten months, it's no surprise that Zawistowski refers to the supernatural when he talks about the project. But when he brings up hocus-pocus, it is as much about the pavilion's aesthetic impression as it is about the speed with which it was brought into being. "We say that it's put together with magic," he mused. "All the connections are hidden—everything's just light and shadow."
