The country, and everyone in it, has been living with the novel coronavirus pandemic for at least five months now. With each passing month, we at The Architect’s Newspaper, like so many others in the AEC industry, trepidatiously await the release of the latest sector reports.

The worst seems to have come and gone with April, when the Architecture Billings Index (ABI) posted record lows. The closing of “nonessential” construction sites and project slowdowns contributed to depressed demand and billings across all regions. But as cities reopened in May, business picked up: June’s ABI showed flashes of recovery, particularly in the Midwest and West.

Signs of optimism appeared elsewhere, only to be followed—below-the-fold, as it were—by disclaimers. In home building, single-family demand has grown markedly since April, although this may have more to do with extremely low mortgage rates than any animating factors endemic to the sector. Whatever the reason may be, sector leaders welcomed the news, even as Robert Dietz, chief economist for the National Association of Home Builders, tempered the mood by pointing out the increasing costs of raw materials. Builders, Dietz said in a statement, “face challenges in growing costs, particularly rising prices for lumber.”

The problem is even more acute outside residential construction. In its June report on nonresidential construction, which parsed data from the U.S. Bureau of Labor Statistics’ Producer Price Index, the Associated Builders and Contractors cited a rise in input prices of 2.2 percent. The uptick follows May’s rise and betrays disruptions in the global supply chain induced by the pandemic. While it’s true that rebounding oil prices largely explain June’s increase, the price of softwood lumber rose by 11 percent in the same time frame. The issue is worrisome, as nonresidential construction—an umbrella category encompassing commercial, institutional, and industrial sectors— will likely be the hardest hit by the current downturn. So suggests the AIA’s midyear report, which projects a steep decline in architectural design billings across these sectors, particularly in office space and retail. And like the material price increases, the billings decline is likely to carry into 2021.

Even businesses considered “essential” Front cover image: Ema Peter

at the start of the lockdown, and thus free from mandated stoppages, aren’t exempt from interruptions. Float glass production has been continuous; manufacturers process hundreds of tons of industrial sheets of glass daily, preparing them to be shipped to and modified by fabricators.

According to Nicole Harris, president and CEO of the National Glass Association, the sticking point for float glass is not manufacturing inputs—sand remains cheap and plentiful. Rather, it’s “really more about the workforce and the crunch time on job sites,” Harris told AN in June. “A lot of companies have already started laying off their workers, right? If the job sites are closed and the factories are closed, then the fabrication facilities are closed.” In other words, the supply of float glass is holding steady, but the fabricators that incorporate the glass into construction-ready products are not immediately able to use it.

But we might resist the temptation to paint too dour a picture. After all, demand for both architectural services and building materials is up in certain sectors, notably healthcare and research laboratories.

Meanwhile, respondents to our State of Manufacturing survey (facing page) were split on the pandemic’s effects and potential aftermath for their respective companies. Some reported little to no change in production or raw material costs. Others expect to see revenue gains in the coming year. None seemed too bothered by the postponement of industry trade shows, those roving emporiums that once marked the passage of time, bracketing the “busy” midyear months on company calendars.

The pandemic has a way of scrambling, and accelerating, time. Five months somehow seems an inadequate container for the numerous disturbances—economic, social, and otherwise—we’ve already experienced; but that same span also feels plodding. Industry reports such as those cited above register the economic effects only belatedly, while forecasts project a recovery that seems ever out of reach. There is, we sense, a mismatch between firsthand experience and macro trends. This discrepancy exists in any time period, but the pandemic has nestled into everyday life to such an extent that the macro feels micro (and vice versa).

Reader Survey

Summer 2020

Reader Survey Midway through 2020, and several months into the coronavirus pandemic, we can confidently say that the building industry has changed. But exactly how it has changed—and how permanent these changes may turn out to be—is difficult to parse. So, we polled manufacturers and architects among our readership to hear more about the specific challenges they and their companies have faced thus far.

We asked about production stoppages, disruptions in supply chains, the rising prices of raw materials, the rise and fall of demand for building products and materials, losses of leads, revenue projections, and more.

The 38 responses, aggregated and reproduced in the following charts and quotes, tell us a few different things. The pandemic is definitely hitting budgets, and layoffs and furloughs

have been common. That much we suspected.

More surprisingly, respondents reported only mild changes to supply chains and construction input prices. Which is not to suggest that architects, manufacturers, and fabricators haven’t been, or won’t be, affected by these shifts—but only time will tell for sure.

“Companies that were already adept at online selling and marketing aren’t experiencing as many issues as those that did not previously make the change.”

from beach morphologies. “Specifically, sand dunes. That’s reflected in the stone colors and the pyramid shape,” Karp noted.

Within each of Arte’s 16 units, living spaces spill out onto spacious, ipe-decked balconies, thanks to operable walls from Schüco. These are supplemented by a gridded window system that runs down the middle of the facade to create a bit more privacy for residents.

Karp said that after studying three or four window systems, the designers chose the Schüco system because of its thin profile and operable and fixed options. The Tecnoglass windowpanes were impact-tested to ensure they could withstand hurricanes and tropical storms.

The distinctive, knife-edged balconies were shaped by structural engineering and local zoning requirements. Pretensioned slabs help them cantilever from the facade without any vertical supports that might block the view, and setback regulations meant that every second floor needed to retreat further from the shore, creating a terracelike feel with plenty of shade.

The building features many bells and whistles that cater to a rarefied market (a 75-foot indoor swimming pool, a rooftop tennis court, climate-controlled parking, lobby art by Olafur Eliasson, etc.), but it’s the giant sliding doors that really turn these condos into the stuff of fantasy as they open onto ocean, sand, and sky.

Slabs of travertine seem to float above one another with only large glass windows between them.

The effect is both effortless and luxe, appropriate for this affluent stretch of the Atlantic coast between Bal Harbour and Miami Beach.

The building’s designers—Milan, Italy– based firm Antonio Citterio Patricia Viel (ACPV) and Miami-based architect of record Kobi Karp Architecture & Interior Design (KKAID)— drew on their respective backgrounds “to create an architecture able to perfectly adapt to the location, while preserving an Italian soul,” said Antonio Citterio. For Citterio, a cofounder of ACPV, the sea-forward lifestyle of the Mediterranean was a constant reference, while Kobi Karp, founder of KKAID, drew inspiration

Innovation formparts.fab by Rieder Causes a Stir in Berlin Bollinger + Fehlig Architects, BDA, and Stoeckert Architects sent an important signal with a new three-dimensional concrete facade made of Rieder products for Lichtfabrik, an office building in Berlin’s Luisenstadt district.

The innovative formparts.fab concrete facade elements played a major role in creating a synthesis between historic preservation requirements and contemporary aesthetics.

The Luisenstadt conservation area, in which Lichtfabrik is located, is subject to specific requirements to protect its urban character. The architects found a solution that met historic preservation guidelines and integrated the new building into the existing urban fabric.

This resulted in a unique facade that at first glance appears subordinate to the surrounding structures. On closer inspection, however, you can see how intelligently and sensitively

the facade of the new building forges its own path. With the formparts.fab products made of glass fiber reinforced concrete, the architects succeeded in articulating the building’s careful design.

formparts.fab as flexible solution for creative architecture Sophisticated architectural concepts like Lichtfabrik’s can often quickly reach the limits of feasibility, but Rieder has specialized for many years in realizing the wishes and visions of special design ideas. In close cooperation with the metalworker and the facade processor, a tailor-made solution was found to manifest the vision of the project’s architects.

A prefabricated substructure was delivered to the Rieder factory, where the formparts.fab

elements were assembled and prepared for delivery to Berlin.

Most of the facade structure was made of polygonal, tilted, and tinted curtain-type concrete elements. “If the virtually animated flowing dress represents a maximum of formal freedom and the faithful replica of a Berlin made of stone represents maximum restriction, then this curtain wall is our synthesis, our way of echoing this discourse through the medium of construction,” said architect Michael Pape of Stoeckert Architects about the concept for the street-facing facade.

Much more than just decoration: the new formparts.fab Because of their low weight and large span widths, Rieder’s formed parts are perfect for

facades with challenging geometries. The new sharp-edged formparts.fab products are not formed from one slat like the conventional formparts.mono; they are assembled from several parts. This makes the elements even more flexible. While the flat concrete skin panels are available in sizes up to about 22 feet long and in a wide range of surfaces, textures, and colors, their substructure is just as straightforward and economical as a facade with straight panels.

Nickel & Associates (now part of Consigli Construction) Glazing manufacturer: Guardian Glass Precast manufacturer: Gate Precast Overlooking New York’s Bryant Park, the residential tower The Bryant cuts a striking yet austere figure in the crowded Midtown skyline.

Designed by the primarily London-based firm David Chipperfield Architects (DCA), the 34-story high-end high-rise is notable for its perfect grid of oversize post-and-beam concrete slabs and operable window bays.

Bryant Park is bounded on three sides by office towers, done up in styles that span the better part of the 20th century. While mirrored glass and other conspicuous finishes that scream “the eighties” predominate, there is also the charcoal brick of the eclectic Gothic art deco American Radiator Building; the park’s fourth edge is defined by the Beaux Arts New York Public Library, clad in milky Vermont marble. DCA, which has an exten- sive background with sensitive infill, devoted considerable effort to pairing the tower with

its neighbors, with particular attention to the building’s material composition. Terrazzofinished precast concrete panels—an effect achieved with an aggregate of white marble, quartz, and variegated limestone—frame generously sized glazing bays, into which ninefoot-tall floor-to-ceiling windows are set.

Operable windows are not in and of themselves novel features in the city’s residential skyscrapers. However, the system used here, Vitrocsa’s Invisible Wall sliding window doors, is notable for its remarkably slender 3⁄4-inch vertical sightlines, which pair well with the tower’s crisp, rectilinear forms.

Manufactured at Vitrocsa’s Culver City, California, plant, the operable windows appear on the north and south facades and are fronted

by Juliet balconies of black vertical pickets.

Compared with a typical curtain wall, Vitrocsa’s system is effectively structural glazing engineered to be operable at both ground level and tower heights. At The Bryant, the 7-foot9-inch by 9-foot-7-inch modules are outfitted with the manufacturer’s MODULAR or TH+ profiles, which are capable of handling greater wind loads. Each module comprises an external and internal insulated glass unit, both of which are operational, with tracks attached to an aluminate plate and water- proofed with silicone and a 1/16-inch sill pan.

The building is expected to open this fall.

Jamilla Walcott Director of Marketing & Product Management, YKK AP America Inc.

Guardian Glass has stayed in close communication with our customers, partners, and employees as the pandemic has progressed. Regular contact means we can be responsive and helpful in addressing their needs to move us all through this crisis.

Like many companies, Guardian is utilizing digital tools.

However, we’ve ramped it up to take advantage of our glass expertise and serve architects’ need for continuing-education credits. In May, we offered the course we planned to debut at the since-canceled AIA Conference on Architecture as part of a trio of live sessions. Continuing-education offerings on glass fabrication, the evolution of glass, and understanding the glass selection process saw great attendance and interaction thanks to promotion and sharing through social media and email outreach.

Guardian Glass is on schedule for commercial product launches in 2020. Digital communication will allow our architects to capitalize on these and all Guardian high-performance, low E-coated glass products for the next generation of projects.

It’s been challenging to connect with architects, who are now working from home on projects. Many of their office voicemails are full, creating a heavier reliance on email. Samples are another area that has been impacted. We’ve adjusted by sending samples to individual architects’ homes, instead of their offices. In some cases, this has required us to send samples concurrently to multiple team members, which has been an unwelcome added expense.

Vitro had already made considerable investments in our own web-based infrastructure, so the transition to “work from home” and internal collaboration was seamless. Extreme western Pennsylvania weather gave us ample opportunity to test the system, and both the equipment and our people were ready when the company was early to institute work-fromhome orders. It has also validated our corporate leadership’s internal communications commitment and tools, such as companywide video town hall meetings and new e-newsletters, to create a climate of solidarity and transparency throughout the organization.

Some of the web-based communications tools we’ve developed, such as remote continuing-education webinars and live chat, will certainly be with us for the foreseeable future.

They are a highly efficient means for connecting architects with important information. As circumstances have required us to find creative solutions, we’ve also discovered some hidden talents and skills of our coworkers, beyond the normal scope of their jobs. There is no doubt that as a new normal takes shape, these newly discovered capabilities will help us better serve our customers and designers.

The biggest pandemic-related disruption from a building products marketing standpoint was the cancellation of industry events for which we had been preparing. Organizers faced tough decisions, while exhibitors and participants didn’t know how to plan. I’ve never experienced anything like it. As everyone came to the realization that in-person events aren’t happening this year, it was interesting to see organizers shift to virtual platforms as well as the adaptation to new forms of relationship development.

Because of reduced travel and our efforts to limit in-person meetings, we’ve seen a similar shift internally. We’ve increased our use of videoconferencing drastically. This climate has made everyone more open to participating on camera, and we are taking greater advantage of the flexibility technology brings. Our sales division is now working to connect with customers virtually, which enables members of the team to engage who wouldn’t have participated before. We have been conducting job interviews online, which is another practice I am sure will continue postpandemic.

Internally, our COVID-19 task force has been working diligently to ensure employees have a safe work environment. We have implemented “new normal” procedures, including social distancing, expanded sanitizing measures, and temperature screenings at our largest manufacturing locations, and are encouraging the use of masks. Employees are adapting, and we are constantly engaging in ways to stay on top of the everchanging tides of this pandemic. When I’m not participating in the task force, some days it is nice to focus on work and “forget” that we are in the middle of a global crisis.

Seattle-based studio SHED Architecture & Design was approached by a local couple to design a detached accessory dwelling unit with an open floor plan and primary functions on one level to accommodate aging in place.

Named Alley Cat, the project is located on the east side of a Seattle lot, nestled between an alley-facing garden and a parking space.

Shaped like a cat ready to pounce, the gable is scaled to adjacent buildings with an asymmetrical ridge oriented to maximize sun exposure.

In an upstairs space, four parallel skylights provide daylight. Down- stairs, strategic pri-

vacy openings include a bathroom awning window and a peekaboo window along the kitchen counter. A sliding door opens the living space to the garden and patio while providing afternoon sun.

Phoenix Law Group approached Phoe- nixbased firm Studio Ma to convert an existing building into an environmentally sus- tainable workplace that could foster company culture.

“The reimagined building needed to feel and operate as one large open office with strong visual connections among staff members, while also accommodating private offices where the firm’s lawyers conduct sensitive, confidential work,” said Christopher Alt, cofounder and principal of Studio Ma. Custom interior glass partitions acoustically isolate enclosed offices and confer- ence

rooms while providing transparency to encourage collaboration. Daylight from skylights as well as the large glass windows and doors that line the building’s exterior filters in throughout. For ventilation, the operable skylights let fresh air into work areas while venting hot air to the roof. A skin of Kebony wood louvers envelops the structure and shades it from the desert sun.

Case Study

The Architect’s Newspaper

Architect: Wayne Turett Location: Greenport, New York

Greenport, New York, on the North Fork of Long Island. Architect Wayne Turett designed the residence as his own home. Drawing inspiration from the local barn vernacular, the carbon-neutral project was made to show how designers can address the climate crisis without sacrificing contemporary expectations of comfort and style.

Turett considered three key elements in the design of the Passive House: “First, the building envelope, which had to be completely sealed so that there was no leakage of air; then the insulation, to ensure that heat would not escape or cold air enter; and finally, the added elements like roof overhangs that

protect the house from receiving too much sunlight in the summer,” he said. As a result of these decisions, the Greenport Passive House consumes nearly 90 percent less heating energy than existing homes and 75 percent less energy than average new construction.

The home also benefits from triple-glazed windows and energy-recovery ventilation, which brings in and takes out air.

The home’s exterior is shiplap gray cedar and cement with an aluminum roof. The insulation works in combination with a proprietary sheathing taped to form the air barrier, allowing for an airtight building envelope. The all-electric home is heated and cooled with a

duct mini-split system aided by an ERV. Inside, a neutral color scheme and light wood materials along with white walls and upholstery create a bright, airy aesthetic. A combined kitchen, dining, living room, and porch were intentionally programmed on the second level with views to the water. Below, bedrooms and bathrooms are accessed via an outdoor shower to smooth the transition from the site’s sandy shores. As an integrated project, the home fuses Turett’s modern aesthetic with a performative building envelope. Eric Baldwin

Case Study

The Architect’s Newspaper

Architect: Oza Sabbeth Architects Location: Sag Harbor, New York

Located on the edge of Long Island in Sag Harbor, New York, the East End House by Oza Sabbeth Architects takes cues from the surrounding landscape. Sag Harbor developed as a working port on Gardiner’s Bay and was designated as the first port of entry to the United States. Today, the village is home to a range of vernacular structures associated with whaling. Inspired by this context and the densely vegetated pond on-site, the East End House reinterprets both regional forms and materials.

The project is bookended by the pond and a busy turnpike. To create a tranquil sense of

place, the home’s form turns away from the sights and sounds of street traffic and toward the pond and forest. The building features a sequence of moments that showcase its layout and materials. The entry is composed of a dense bulwark of concrete and wood, as well as an intimate forecourt. From there, an entrance foyer opens up to the landscape and pond. The organization in plan generated a private front and an accessible backyard with multiseasonal outdoor spaces on the lowest level.

Oza Sabbeth experimented with using substrates as finish materials for the home. The

roof and walls are designed as a rainscreen assembly of exposed rubber (EPDM) and mahogany decking material. “The substrate, EPDM in this case, is revealed in instances and slips behind the mahogany shell where needed,” said Oza Sabbeth principal Nilay Oza. The flooring is a poured self-leveling concrete, typically used as a substrate for tile. For the millwork and wall panels, the team used a Baltic birch platform as a base upon which more expensive finish veneers were applied.

ate complex forms. In a play of light and shadow, the team used the concept of “the fold” to shape a roofscape that connects the gabled facades of each unit. Waechter decided to use Hardie siding and asphalt shingles to bring together the exterior walls and roof surface.

To enhance the desired qualities of shadow relief and texture, the designers went beyond cladding with several techniques, including a flashing detail and window placement.

Principal Ben Waechter explained the approach, noting, “At a building scale, we folded the facade, and at each of the folds there is a special detail that visually gives the impression that the facade plane has been scored

and folded. This three-piece flashing detail allows the fold to bend at a concave or convex angle. All the windows are recessed into the wall cavity rather than attached directly to the outside face of the sheathing. With the windows recessed, the trim is able to be applied perpendicular to the facade, giving it more visual depth than what is typically achieved with standard flat trim.”

Origami is a study in scale and balance for new multifamily housing. The project’s concept provided individual articulations of each unit while maintaining the sculptural impact of the whole, and in turn, created a subtle identity for the development. Eric Baldwin

In cities across the country, a new class of towers celebrates structural lines while pushing technological boundaries.

By Matthew Messner

HUF TON+CROW

Zaha Hadid Architects’ One Thousand Museum tower in downtown Miami features an innovative glass fiber reinforced concrete frame.

When 875 North Michigan Avenue, formerly the John Hancock Center, opened on Chicago’s Magnificent Mile in 1969, it signaled a departure from the all-too-prevalent trabeated Miesian skyscraper. Its subtly tapered 100-story form and iconic X-frame structure, designed and engineered by Skidmore, Owings & Merrill’s Bruce Graham and Fazlur Khan, respectively, demonstrated that beauty and structural performance need not be mutually exclusive. As if taking this lesson to heart, a new crop of expressively framed towers has sprung up around the country in recent years,

each one upping the ante in exuberant form and structural daring.

In Seattle, a short walk from the city’s famed, OMA-designed central library, The Mark gamely cantilevers over its older neighbors.

The 48-story hotel-and-office tower, designed

by ZGF Architects and engineered by Arup, relies on a hybrid steel “megabrace” and concrete core structure to perform its acrobatic feat. Comprising multistory steel members, the triangulated megabrace—so termed by Arup—addresses the structural complexities of building a formally expressive tower in the

volcanically active region. The architects also rehabilitated the two historic structures nestled below The Mark’s protruding midsection: the First United Methodist Church (now an event space) and the Rainier Club. Their efforts have resulted in an eclectic city block, complete with classically proportioned low-rise structures and a decidedly contrapposto tower.

In San Francisco, the Heller Manus Architects–designed 181 Fremont employs a similar megabrace structure (again courtesy of Arup) capable of withstanding the city’s seismic activity and ever-present wind loads.

But the slightly tapering tower also deploys a structurally integrated damping system (rather than the more typical tuned mass damper), which enabled the architects to increase the tower’s height; at 802 feet, 181 Fremont is the tallest residential high-rise on the West Coast.

And because the shocklike dampers work in-line with the megabrace, the design team was able to eliminate 3,000 tons of steel from the project. The envelope created additional efficiencies; calibrated to the angle of the sun, the “saw-tooth” glass facade reduces solar gain by 6 percent. continued on page 34

In San Francisco, Heller Manus Architects has designed 181 Fremont, which makes cunning use of a structurally integrated damping system.

continued from page 32 In a departure from the steel systems normally associated with exoskeletal structures, Ateliers Jean Nouvel turned to concrete for the French firm’s first residential tower, 53 West 53 in Midtown Manhattan. At almost the same supertall height of 875 North Michigan Avenue, 53 West 53 even takes some aesthetic cues from the Chicago icon, but the similarities are superficial.

Nouvel’s skyscraper was meant to be even taller, but political and economic exigencies— negotiations with city planning, the Great Recession—prompted a complete structural

luxury high-rise employs a unique structural system made up of 4,800 prefabricated glass fiber reinforced concrete (GFRC) panels. The pieces, which were individually fabricated in Dubai and test fitted before being shipped to the dense Miami lot, act as both concrete formwork and finished surface. Whereas 181 Fremont and The Mark contend with intense seismic conditions, One Thousand Museum is faced with a very real hurricane threat. The structural system was put to the test perhaps earlier than expected when Hurricane Irma, a Category 4 storm, struck Miami in September

rethink, including subbing out the steel for reinforced concrete. Sloping and slanting up to a pointed precipice, the structure trades a normal diagrid for highly irregular facets, palpable on the exterior as well as the interior.

The result is a celebration of the structure in all of the building’s 145 units, each with expansive windows spanning massive diagonal structural members.

In downtown Miami, One Thousand Museum takes the possibilities of concrete to even further extremes. Designed by Zaha Hadid Architects and engineered by DeSimone, the

2017, as construction was underway. By exploring the formal potential of GFRC, the svelte tower sets a new bar for aesthetic, structural, and construction methods. As a proof of concept, it represents a dramatic advancement of 875 North Michigan Avenue’s revolutionary construction, while opening new doors for expressionist towers to come.

Fabrication Futures

Facade engineers discuss the international trend of custom repetitive manufacturing.

Computer-aided manufacturing has revolutionized the field of facade manufacturing over the last decade. Dana K. Gulling, author of Manufacturing Architecture, describes the overall trend as one of “custom repetitive manufacturing,” which reestablishes a level of customizability in industrial processes and facilitates fruitful collaboration between architects, facade engineers, and manufacturers from the design-assist phase to completion. To learn a bit more about the shift, AN surveyed leading facade engineers about how it affects their work. By Matthew Marani

COURTESY HATFIELD GROUP COURTESY FRONT INC

Erleen Hatfield Managing Partner, Hatfield Group Custom repetitive manufacturing (CRM) has the potential to change how we design and construct buildings by making advanced digital design processes—like computational and parametric design—a viable option for a broader range of clients. This results from custom-designed elements being fabricated cost-effectively and with minimal production waste. In our work as a design-driven engineering firm, we embrace CRM as a powerful tool for realizing even the most technically demanding architectural designs.

Before CRM, fabricating the type of custom elements associated with these processes was too expensive for most clients—it only made sense for high-budget projects, so the tremendous potential of digital design methods could not be realized on a broad scale.

COURTESY SURFACE DESIGN GROUP COURTESY BURO HAPPOLD

Michael Min Ra Cofounding Partner, Front Inc Key factors driving the realization of custom systems and components are a combination of conceptual demand and corresponding supply through advancements in and adaptations of technology in design tools, transfer of data, and compatible methods of manufacturing.

This sequential exchange of digital data from relatively low-resolution initial design to highly refined final solution enables successful custom fabrication and assembly of parts, and variability within given system parameters and schedules.

This mode of practice is applicable to both repetitive and variable facade typologies.

Repetition offers profound advantages in allowing more detail definition with simplified cost control, whereas variety can be accommodated through instantiation. As the costs of digital design processes diminish and designers’ manufacturing and construction knowledge expands, this process of customization will proliferate to the extent seen in other industries that benefit from economies of scale.

Anna Wendt Director, Buro Happold Repetitive manufacturing has long been admired from a cautious distance by both engineers and architects. Cost efficiency, precision, mass production, and shorter lead times are advantages that shouldn’t be ignored. The increasing opportunity to introduce unique, customizable features to the repetitive manufacturing process provides further opportunities for ensuring that a sense of craftsmanship is achieved for iconic buildings.

An example where the Buro Happold facade engineering team has pioneered the use of such technology is on the King Abdulaziz Centre for World Culture in Dhahran, Saudi Arabia. The project, designed by Snøhetta, has a unique facade comprising an intricate surface made from 215 miles of CNC-bent stainless steel tubes. Innovative planning and design allowed the design to be optimized and developed for production by the facade contractor seele.

Benson Gillespie Partner, SURFACE DESIGN GROUP The ability for fabricators to provide custom facade systems has been a blessing for smaller and midsize projects. Our 10 Jay Street project [in Brooklyn, New York], designed by ODA, is a great example of this trend, where a completely custom curtain wall system was used to achieve a geometrically complex facade design at a relatively limited scale. We expect that custom facade systems will only increase throughout the industry as parametric software becomes more integrated within design and fabrication processes.

This trend has led to an increase in the numbers of international fabricators participating in the design-assist and bidding processes, as their custom systems are often competitively priced in comparison with standard systems offered by local vendors.

This leveling of the global playing field has significantly expanded the options available to designers and owners.

COURTESY STUDIO NYL

Chris O’Hara Founding Principal, Studio NYL The most important aspect of maximizing custom fabrication in mass production is to use the technology judiciously. Oftentimes in our studio, we try to take complex forms and develop them for modest budgets. To achieve this goal, we use a “kit of parts” mentality. We use mass-produced extrusions for glazing systems and mass-produced cladding support systems for our opaque cladding, and marry them with a substructure that can be digitally fabricated or arranged in a unique geometry to realize complex forms or longer spans.

Often lost in our ability to fabricate is the reality of installation. We can solve the translation of fabrication to installation through panelization, but in our experience it often is the marriage of high tech and low tech that leads to the best results. The fun and challenge is: How do we manipulate the systems our installers are comfortable with and use basic principles to make them unique?

COURTESY HEINTGES

COURTESY DESIMONE CONSULTING ENGINEERS

Ashley Reed Director, DeSimone Consulting Engineers When we consider the repetitive manufacturing and automation of building enclosure systems, we need to evaluate three distinct phases: design, fabrication, and installation.

Advances in fabrication technologies and installation practices are instigating a collapse of the latter two phases. However, people are still superior at improvising and handling the complexity of on-site conditions and fabrication. Enclosure systems consist of assemblies designed to withstand loads and integrate varying levels of boundaries to control heat, air, and moisture. Currently, the fabrication of assembly components is automated, but the compilation of these components into the ultimate assembly is still largely reliant on human labor.

COURTESY THORNTON TOMASET TI

Alloy Kemp Associate, Thornton Tomasetti Custom repetitive manufacturing has forced us to be smarter about where we implement custom solutions and repetitive processes.

Designing bespoke facades, even if they’re easier to realize now, still can incur increased cost. For example: Processes like heatwelding ETFE panels or laying up composites over a mold can be programmed to be repeated even when the physical output is different.

But for curtain wall extrusions, numbers of dies are still a major cost factor. Attaching mullions at varying angles is less influential on cost. While we’re past the point of specifying one typical detail, not everything can be made fully custom at the same economy. It’s the fun, exciting challenge of being a facade engineer: to make complex facades developable from a repeated kit of parts and processes.

Karen Brandt Senior Principal, Heintges Although custom repetitive manufacturing is not a new technique for some materials in facades, like terra-cotta, exploration and advancement of the design potential of custom repetitive manufacturing is increasingly a part of our consulting work with architects. We’ve observed a shift in interest from designing “one-off” final products to interest in custom tools used in the fabrication process that have the potential to amplify the value of both human and machine fabrication time. There is a fascinating range in “custom tool” approaches: from an extremely expensive but reusable tool used for the fabrication of complex bent architectural glass to an extremely inexpensive, but ultimately disposable, CNC-routed foam mold for architectural precast concrete.

Sustainability will ultimately be the most important consideration to advance these approaches.

Architectural designers: Diller Scofidio + Renfro, Rockwell Group Location: New York Facade manufacturers: Vector Foiltec, Cimolai, CS Facades Facade installer: Sciame Construction Structural engineer: Thornton Tomasetti System: Custom steel shell clad in ETFE panels Product: Texlon ETFE Hudson Yards, the mega-development reshaping Manhattan’s Far West Side, needs little introduction; it has been both praised and vilified for its gigantic scale and contentious urban ethos. Regardless of the controversy surrounding it, the project showcases some ambitious engineering. Designed by Diller Scofidio + Renfro (DS+R) with Rockwell Group, The Bloomberg Building’s versatile ETFE cladding and mobile shell exemplify the development’s remarkable construction.

The Bloomberg Building, home of The Shed, a cultural center, is a multipurpose structure composed of four stories of loftlike spaces clad in a unitized glass curtain wall.

The building is encased in a pillowy shell of diamond-shaped ETFE panels that rest on six gargantuan tracked wheels—bearing some resemblance to the industrial shipping infrastructure formerly located on the nearby Hudson River.

ETFE is a pliable and lightweight alternative to glazing. The Shed lies atop Hudson Yards’ overall foundation, which is composed of a vast network of trusses spanning old rail yards below, and the use of heavy insulated glass units would potentially overload this nonadjustable structure. According to DS+R associate principal Charles Berman, ETFE was also chosen for its spanning capabilities and

inherent flexibility. “ETFE can be fabricated into much larger, self-supporting, pneumatic cushions that allowed the facade to enclose the structural steel frame without intervening substructures of aluminum or steel,” Berman said. “ETFE’s flexibility permitted DS+R to address the dynamic deflections that The Bloomberg Building experiences when in motion without the complex moment allowances and expansion joinery that a glass and metal facade would require.”

Collaboration proved crucial to the project.

DS+R, facade consultant and structural engineer Thornton Tomasetti, contractor Sciame, and fabricators were involved from the early design-assist phase. According to Thornton Tomasetti associate Alloy Kemp, the early stages of the design sought to push the limits of the ETFE panel size while meeting the daylighting and acoustical requirements of the performance space within. The structural steel frame is girded with a U-shaped upstand that is fastened at key points; fabricator Cimolai assembled each component in Pordenone, Italy, prior to shipment to New York. Once in place, the steel shell was outfitted with aluminum extrusions and plates, and then the ETFE panels were installed. Inflation tubing was set for each panel during the installation process.

The material and location also presented unique challenges for the contractor. “ETFE must be installed in temperatures above 40 degrees Fahrenheit. Any colder and the material becomes brittle and will lack the pliability needed for installation,” said Sciame senior vice president Steven Colletta. “Getting the material to look right—it cannot be too tight or too slack—required a great deal of field adjustment and coordination to account for the anticipated movement of structural steel, all the more complicated because of Hudson River–borne winds.” Matthew Marani

Lucas Museum of Narrative Art

COURTESY LUCAS MUSEUM OF NARR ATIVE ART

Architect: MAD Architects Location: Los Angeles Architect of record: Stantec Architecture Enclosure consultant: Walter P Moore GFRP panel fabricator: Kreysler & Associates The form of the Lucas Museum of Narrative Art is suggestive, shape-shifting, not unlike the popular media to which the nascent institution is dedicated. Under construction since 2018, the curvilinear 290,000-square-foot museum is beginning to animate the entire western edge of Los Angeles’s Exposition Park, a 160-acre park opposite the University of Southern California. The project, which is named after its chief benefactor, the filmmaker George Lucas, joins a loosely cohered complex of cultural and recreational destinations, including the Natural History Museum of Los Angeles, the California Science Center, and

the Los Angeles Coliseum.

In 2014, the Beijing-based firm MAD Architects prevailed in an international design competition that tasked participants with translating the lofty, future-oriented miseen-scène of the Lucas brand into a landmark piece of architecture. After a lawsuit prompted the museum to relocate from Chicago to Los Angeles, MAD refined its winning proposal into a stunningly amorphous “creature” with nary a right angle in sight, popularly likened to a spaceship by locals and critics alike. Containing a permanent collection and rotating exhibits dedicated to the media of filmmaking, in addition to theaters, classrooms, and a free public research library, the sweeping structure gracefully (in renderings, at least) spans 185 feet at its center to form a new gateway to Exposition Park.

The enormous building rests on a base isolation system that will gently rock the

structure in the event of an earthquake. But in order for that system to work, the design team had to be extra mindful of the weight of the outer paneling, or rainscreen. After it was discovered that glass fiber reinforced concrete (GFRC), a composite material popular among architects of curvilinear building facades, would overburden the base isolation system, the team opted for glass fiber–reinforced plastic (GFRP), a highly durable composite material a fraction of the weight of GFRC. The chief benefit of both composites is the supersmooth exterior surface they can yield, provided that panels interlock in just the right way. To that end, MAD enlisted an army of tools including Maya, Rhino, Dynamo, and Revit, each with a number of plug-ins and custom scripts. The architects sent all this modeling information over to Kreysler & Associates’ production facility on Mare Island, in Northern California, where each of the 1,500

GFRP panels is being fabricated. There, a CNC machine cuts out custom foam molds, into which a resinous mixture is injected; after the curing process, robot arms scan the panels to verify their dimensions and contours before sanding them to a smooth finish.

The panels will then be shipped to Exposition Park, where, beginning this month, they will be installed in a secondary structure of variegated trusses branching off the burly primary structure, which is made up of predominantly straight beams. At the time of writing, the museum’s superstructure is only halfway erected, the first outlines of a cinematic vision. For now, observers will have to fill in the gaps—or scene—themselves.

Sidney & Lois Eskenazi Hospital: An Example of Repelling Water with Mineral Wool by Owens Corning

COURTESY ESKENAZI HEALTH

In the Sidney & Lois Eskenazi Hospital, Indiana’s first LEED Gold health care building, Thermafiber RainBarrier insulation helps manage liquid and vapor moisture in the exterior assembly.

The Sidney & Lois Eskenazi Hospital is deeply rooted in Indianapolis’s history. Founded as Indianapolis City Hospital in 1859, the hospital was used during the Civil War to care for Union soldiers. The hospital’s name changed several times before it reopened in December 2013, 1300 feet west of the original site in a building designed by HOK. Certified in 2015 as Indiana’s first LEED Gold health care building, the Eskenazi Hospital is one of the largest LEED Gold health care campuses in the world. Moisture management is integrated into the design of the hospital

enclosure, specifically in the exterior wall assembly. Installed as continuous insulation, Owens Corning Thermafiber RainBarrier efficiently repels and drains water from the wall cavity system, while also delivering energy efficiency and fire-resistant properties.

David Williams, senior project manager of Quality Interiors, one of the project’s contractors, witnessed firsthand how mineral wool stood up to rain during construction. “We had our own version of a Midwest monsoon come through, and I received a call from the hospital’s transition team saying they were worried

a lot of job site material was getting wet on the insulating material,” Williams said. He calmed the caller’s concerns, noting that the product— RainBarrier insulation—was living up to its name. “I said, ‘Are you kidding? It’s designed to repel water,’” Williams recalled, adding that the insulation had completely dried by the time members of the transition team came over to check out the situation.

Among mineral wool’s diverse performance properties, its ability to manage both liquid and vapor is especially important in the wall cavity system, where it is imperative that

water not become trapped inside the cavity.

With a minimal sorption of just 0.03 percent, even in the harsh climatic conditions measured by ASTM C114 (120 degrees Fahrenheit, 95 percent humidity for 96 hours), Thermafiber insulation delivers consistent thermal performance throughout the thickness of the mineral wool. And when mineral wool does get wet, its specially engineered properties help it quickly revert to a dry state. The abilities to repel moisture and dry out following exposure make mineral wool a solid choice for continuous insulation in exterior assemblies.

Keating

In designing the Charles Library at Temple University in North Philadelphia, Snøhetta wanted to make a contemporary statement that would integrate harmoniously into the pedestrian core of a leafy, architecturally diverse urban campus that is still largely defined by historic stone masonry edifices.

The resulting building, a research library clad in stone, wood, and glass and topped with one of Philadelphia’s largest green roofs, achieves this goal with aplomb. Completed in August 2019, the 220,000-square-foot library serves as a bold yet welcoming center of gravity for the surrounding landscape.

“In the course of identifying the strategic goals of the project, we identified a strong need for the library to be a magnetic heart of the campus—and embracing, so to speak,” said Snøhetta project manager Chad Carpenter. “It’s a place that people want to come to that’s at the heart of their path between all the different departments on campus.”

The designers wanted the library to reference the stately stone facades of neighboring buildings. After considering the use of precast concrete panels, the team ultimately chose an open-joint stone rainscreen system when budget calculations showed that the former would not be viable. Six-inch vertical sections

of split-faced Mesabi black granite sourced from Minnesota-based quarrier and fabricator Coldspring clad much of the building.

“A lot of universities have a fairly rigid material palette, but Temple’s campus has evolved in a different way,” Carpenter said.

“But a lot of the most important and oldest buildings on campus are stone buildings. And we picked up a little bit on the way in which those buildings used stone. We weren’t trying to make a contextual building. It’s a contemporary building that also speaks to the materiality, solidity, and durability of some of the best buildings on campus.”

Cut into the building are its main portals and pièces de résistance: soaring western red cedar archways that lead into a triple-height domed atrium lobby that’s also clad in a thicker version of the same ACGI cedar.

“Often in architecture there’s a desire to control color and texture, and to know exactly what you’re going to get,” Carpenter said.

“Cedar has quite a bit of color tone variation so that when you have this geometry that’s allencompassing and enveloping, that variation and liveliness in color and tone breaks it up and keeps it from becoming overwhelming.”

In addition to warmth and variation, cedar is particularly resilient in outdoor applications

and easily bendable, which allowed the team to avoid cutting and carving the material using CNC machines. The cedar components were assembled flat and then shipped to the site, where they were bent.

The library’s swooping wood-lined portals help open the library to the rest of the campus. A smaller corner entry, which directly faces one of Temple’s busiest pedestrian intersections, creates a sheltered plaza that looks straight through the library’s sprawling lobby to a larger arched entry on the opposite side of the building.

“That sort of porosity of the building and embedding the desire lines of the campus right into the circulation flow of the library was very much part of the design,” said Carpenter.

Case Study

The Architect’s Newspaper

Architect: James Carpenter Design Associates Location: New York

on display once more in the facade of the new Nordstrom flagship in New York, located at the base of the Adrian Smith + Gordon Gill Architecture–designed Central Park Tower, which will be the world’s tallest residential structure when finished. The store’s undulating curtain wall, made of curved and supersize glass panels, ripples across seven stories of the tower’s south and north elevations. According to JCDA, the wavelike form is an homage to the rivers bounding Manhattan.

Spanish glass manufacturer CRICURSA— one of the few manufacturers worldwide with the technical capacity to produce extra-large curved glass panels—was pulled into the project at an early stage. “The design started with the glass itself and worked out to the surrounding frame system, so ensuring the bent profiles were achievable in terms of structure,

manufacturing, handling, and shipping was important in the early design stages, most critically in the visual mock-up and the performance mock-up stages,” JCDA studio director Joseph Welker explained.

In total, there are five typical profiles and four unique corner profiles, and their dimensions range in height from 17'6" to approximately 19'6", and in width from 3'10" to 6'2".

The result is a succession of convexities and concavities following an A-A-B-B rhythm, which create occupiable spaces similar to those of bay windows. The curtain wall is backed by a diaphanous steel mesh veil; like the curtains in the Pool Room of the nowdefunct Four Seasons restaurant in the Ludwig Mies van der Rohe and Philip Johnson– designed Seagram Building a few blocks to the east, the veil filters daylight and adds

depth to the facade.

It is difficult to overstate the complexity of the curtain wall system, and New York– based facade consultant SURFACE DESIGN GROUP played an essential role in developing a design that balanced aesthetic concerns, thermal performance, structural behavior, and code compliance. “The final glass composition was developed as a slump-formed, complex-curved, insulated glass unit, comprised of various layers of laminated, low-iron glass and a subtle, custom ceramic dot frit pattern,” said SURFACE DESIGN GROUP partner Benson Gillespie. “Aluminum mullions were stretch-formed to an exacting tolerance that matched the glass.” Matthew Marani

Timber-rific

Summer 2020

Three engineers describe their most innovative timber projects. By Matthew Marani Eric McDonnell Principal, Holmes Structures I have been lucky enough to work on a number of innovative mass timber projects this year.

These include Redfox Commons, designed

by LEVER, which utilized salvaged timbers to create a connecting building between two refurbished historic warehouses; District Office, a six-story mass timber building designed by Hacker that is the future home of our Portland office; NIR Center (bottom), designed by Hennebery Eddy, a proposed ten-story hybrid structure of mass plywood floor panels and steel DELTABEAMs utilizing the new Type IV-B heavy timber building regulation approved for the 2021 International Building Code; and the Adidas North American Headquarters

expansion project, also by LEVER, which is using a unique hybrid structure of mass timber floor cassettes and precast concrete beams and columns (below). The most innovative of all would likely be Katerra’s Catalyst Building in Spokane, Washington, the first project to use CLT panels made in Katerra’s new manufacturing facility. This five-story office and classroom building is constructed almost entirely of mass timber, including CLT ribbed floor panels, glulam beams and columns, and CLT cladding panels, along with the first use of CLT shear walls utilizing buckling-restrained braces (BRBs) as ductile hold-down elements.

MORIYAMA & TESHIMA ARCHITECTS

Paul Fast Founding Partner, Fast + Epp Perhaps the most groundbreaking project we have been working on this year is The Arbour, a new ten-story building for George Brown College in Toronto designed by Moriyama & Teshima Architects (above). It features a novel structural system consisting of the slab-band arrangement commonly used in concrete construction, but replaces most of the concrete with mass timber. Composite CLT-concrete slab bands with an overall thickness of 15.5 inches span 30 feet between large 1.4-foot-by-3.9-foot timber columns, and

infill 6-inch-thick CLT panels clear span 15.5 feet between the slab bands. Central stair and elevator cores consisting of steel columns and diagonal bracing provide lateral resistance for the building. The end result is a primarily timber construction floor system that offers a thickness and flat soffit comparable to concrete construction but with a sharp reduction in both embodied carbon and construction time. The exposed timber flooded by ample daylight will also create a wonderful physical work environment for students and faculty.

COURTESY HOLMES STRUCTURES

HACKER ARCHITECTS

Anne Monnier Principal, KPFF

HENNEBERY EDDY ARCHITECTS

While we completed several mass timber buildings over the past five years, the sheer quantity of projects getting to the construction stage last summer was a new record.

Two projects in Portland, Oregon—the Adidas North American Headquarters, designed by LEVER Architecture, and the District Office, designed by Hacker Architects (above)—saw their structural frames go up this past year.

The District Office features an innovative optimized, fiber-count mass timber frame that utilizes a tight colonnade column layout in one direction with long-span glulam beams. Not only does it allow for a clean, fully exposed, one-hour fire resistance–rated mass timber

frame for maximum daylighting, but it also enables organized routing of MEP systems.

This is further developed by providing chases between CLT panels to allow for smaller distribution lines such as conduits and sprinklers.

The Adidas expansion encompasses a more traditional column layout with double-glulam girders in the South Building and precast concrete girders in the North Building, both accommodating MEP routing through and/ or over the girders coupled with a panelized CLT and glulam beam floor system. Speed of construction and fewer pieces to handle were key drivers on this fast-track project.

by Leers Weinzapfel Associates, Mackey Mitchell Architects, and modus studio for the University of Arkansas, is the largest cross-laminated timber (CLT) building in the United States. The name of the project honors the Cherokee, who passed near the site while being forced to march the Trail of Tears. Adohi, the Cherokee word for “woods,” was chosen in consultation with citizens of the Cherokee Nation and references the sustainably sourced wood used in the CLT construction.

Completed in 2019, Adohi is a distinctive new gateway to the University of Arkansas in Fayetteville. Its series of interconnected timber structures and courtyards rests on a sloping, 4-acre site at the southern edge of the campus. A serpentine band of student rooms connected by a ground-level passage defines three distinctive courtyard spaces for interactive learning in architecture, design, and other arts. The 202,027-square-foot building includes classrooms, maker spaces, performance spaces, administrative offices, and faculty housing. Advanced timber technologies, like CLT panels and glulam beams and columns, were integrated throughout to reduce the carbon footprint of such a large and complex building.

The building’s interiors celebrate the timber structure. Exposed structural wood ceilings are used in the student rooms, study rooms, floor lounges, and ground floor common spaces. The project’s main gathering space, the Cabin, also features a wood ceiling and trusses that span the full width of its lounge spaces. Outside, a light metal jacket of zinc-toned panels with copper-toned and white accents covers bars of living space that seem to float above the glass-clad base and the landscape below.

Mass Timber

Products

Summer 2020

The latest mass timber products have strength, stability, and design flexibility. These cross-laminated timber (CLT), glued-laminated timber (GLT), and structural composite lumber (SCL) products can realize building heights and spans that would have previously required steel, masonry, or concrete structural support. By Gabrielle Golenda

Brisco Fine Line Panels Brisco Manufacturing Ltd.

KLH Cross-Laminated Timber KLH Massivholz

Nordic X-Lam Nordic Structures

Ideal for floor, ceiling, wall, or roof applications, these laminated veneer lumber (LVL) panels are designed with layers of thin scarf jointed veneers. They are offered in sizes up to 11½ inches thick, 48 inches wide, and up to 60 feet long.

These spruce CLT panels come in two types (transverse and longitudinal) and have three structural applications: for walls (transverse panel); and for slabs and roofs (longitudinal panel).

Both panel types are made with double layers to increase rigidity and can be up to 55 feet long, 10 feet wide, and 1½ feet thick.

Nordic Structures CLT is fashioned from three orthogonal layers of lumber laminated with glue and structural adhesives.

It can be used in wall panels, floor slabs, roof slabs, and light framing.
