Mecanoo’s Delft city hall and train station reflects the past with ornamental glass panels

facadeplus_logo1
Brought to you with support from
Constructed in the center of the canal-ringed Dutch city of Delft, Mecanoo Architecten’s new City Hall and Train Station conveys an up-to-date take on the city’s overarching morphology and history with an expressive glass facade and articulated massing. Delft is located approximately 10 miles from the Port of Rotterdam, one of the world’s busiest, historically embedding the city within European and international trade flows. The city’s primary product was a style of tin-glazed ceramic dubbed Delftware, which largely consisted of blue detailing laid over white porcelain. Protected by relatively stringent architectural conservation regulations, the city still largely follows its centuries-old layout of narrow streets, plot lines, and modest building heights. The challenge for the architectural practice was to incorporate these elements into a 305,000-square-foot, state-of-the-art infrastructural hub and seat of government.

The complex rises from a vaulted and mosaic-tiled four-track train station, with the first floor largely serving as a conduit of circulation between the streetscape above and transport embedded below. Floating above the station’s principal concourse are approximately 2,000 425-foot-long curved ribs printed with a historic map of the Delft region in 1877. The glass panels are primarily a single height of approximately 11.5 feet, with varying widths of 1.5 to 3 feet. Each panel was glazed a soft blue in homage to eponymous ceramics formerly produced in Delft. Working with curtain wall fabricator AKS Bouw, the design team utilized a custom-designed aluminum framing system, hanging each facade element from the interior with a specialized hook. For fabrication and glazing of the glass panels, Mecanoo Architecten collaborated with specialist St. Gobain. Kiln forming was used to imprint street-facing panels with their lens-like spheres, a vernacular detail commonly found within the city. According to the design team, this kiln forming process is fairly straightforward: “a regular sheet of float glass is heated and put over a mold containing holes for the heated glass to drop into, the ripple effect is formed by a nose that sits at the center of the hole." From the second story, the structure rises as an irregular glass mass measuring nearly 50,000 square feet in surface area. Mecanoo used two strategies to relate the complex’s volume to the city-at-large: deep incisions punctuate the east and west elevations of the street wall recalling the city’s network of alleyways and courtyards, while the roof gradually slopes downward towards each corner to match surrounding cornice lines.

Brought to you with support from

The 2011 Christchurch earthquake devastated much of New Zealand's capital city, knocking down or severely compromising civic buildings across the metropolitan area. Located within the cordoned off Central City Red Zone, the Christchurch Central Library was closed to the public for three years prior to its ultimate demolition in 2014. Completed in October 2018, the new Central Library, titled Turanga after the Māori word for base or foundation, designed by Schmidt Hammer Lassen Architects features a luminous perforated aluminum veil that cloaks a seismically engineered unitized curtain wall assembly.

The 102,000-square-foot library rests atop a rectangular stone-clad podium detailed with expansive representations of Māori artwork. Rising to a height of five stories, the facade fissures to orient itself toward local geographic landmarks, including the mountain ranges of Maungatere, Ka Tiritiri o te Moana, and Horomaka.

  • Location Christ Church, New Zealand
  • Date of Completion October 2018
  • System Unitized glass curtain wall with clip-on cassette metal veil
  • Products Metal Concepts perforated aluminum sheets, Alutec unitized thermally broken aluminum curtain wall

The principal facade element, a wedge-shaped aluminum perforated panel system, was designed as an oversized evocation of the native evergreen species used for traditional Māori textiles. Each panel is approximately a standard height of just under five feet, with widths varying between two, four, and six feet. Similar to the flexibility considerations of the concrete structural system, the design team placed an open joint between each story of perforated panels to allow for differential movement during a seismic event.

For the golden veil that courses across the facade, Schmidt Hammer Lassen Architects coordinated with local fabricator of architectural metalwork, Metal Concepts. The aluminum sheets were pre-anodized to ensure color consistency and were subsequently cut, perforated, and folded into their respective shapes. To connect the panels to the curtainwall assembly, each is outfitted with a slotted hole at the rear of the frame which is fastened to a series of hooks extending from the story-height mullions of the unitized curtain wall. 

The perforations of the aluminum panels follow an approximately 2.5-square-inch triangular grid, with an indentation located on the corners of each triangle. Measuring just under an inch in diameter, the perforations play two roles; accentuating the depth and texture of the facade–the luminosity of the aluminum panels intensifies at sunset–and filtering light through the glass curtain wall.

For the design team, which worked in collaboration with Lewis Bradford Consulting Engineers, one of the crucial considerations for the facade and structural systems was durability during a future seismic event. According to the architects, this seismic force-resisting system is composed of a series of flexible concrete walls that shift during earthquake accelerations. With a system of “high tensile, pre-tensioned steel cables that clamp the wall to the foundations with approximately 1,000 tons of force per wall,” the building is capable of returning to its original position following a sizable earthquake.

In 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.

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 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.

Raw facade hardware gets spotlit in this flagship in New York’s Meatpacking District

  facadeplus_logo1
Brought to you with support from
Since the construction of the High Line’s first section in 2009, Manhattan’s Meatpacking District has undergone a dramatic transformation from a declining industrial district to a burgeoning site of development attracting leading national and international firms. Now, California’s Backen & Gillam Architects has stamped its presence in the neighborhood with a modern aluminum-and-glass screen wall inserted atop a restored historic reddish-brown brick warehouse.

  • System Pre-fabricated aluminum screen wall
  • Products Custom-designed black aluminum frames
Located on the corner of Little West 12th Street and 9th Avenue, the nearly 100,000-square-foot project for the retailer formerly known as Restoration Hardware, now known as RH, is within the stringently-protected Gansevoort Market Historic District. The building itself was constructed over a century ago as a retail warehouse, and ultimately transformed into a garage for the renowned Astor family. For project lead Jim Gillam, the constraints set by the Landmarks Preservation Commission pushed the design team to draw upon the neighborhood’s prevailing historical elements: the bolts, splices, and rivet patterns found on steel and cast-iron awnings, as well as elevated infrastructure. The new black aluminum frames primarily consist of a set of prefabricated components. Each frame is composed of two aluminum cross braces which are fitted to a set of turnbuckles, allowing for the adjustment of tension across the screen wall. T-frames studded with bolts are the primary vertical and horizontal elements of the screen wall. These can be split into two categories: structural members that run the length of the elevation and drive into the building below, and beams supporting the overall rigidity of the frame. This entire system is connected to an array of vertical mullions through existing steel brackets and a new screen wall connector. For the project, Backen & Gillam worked closely with the manufacturer, Ahlborn Structural Steel, to produce a kit of parts that was easy to assemble on site. Every component shipped from Santa Rosa, California, was designed as a three-piece unit set to maximize space on the convoy of flatbed trucks that carted them across the country. Each aspect of the screen wall, down to the bolts, were numbered and classified to ease their installation. In total, the design and construction teams were able to erect the entire addition in approximately two weeks. Gillam's interior spaces maintain the structure's historical bones while providing room to breathe for the new. The central and defining moment of the internal spaces is the light-filled, six-story atrium extending the full height of the complex, with successive rows of fluted Corinthian columns bordering aluminum-and-glass balconies.

An Estonian office block receives a splash of color with an aluminum mesh facade

Estonia-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.

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 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.

Undulating fins create a monumental entryway at the revamped Miami Beach Convention Center

facadeplus_logo1
Brought to you with support from
The Miami Beach Convention Center is getting redesigned into a new 1.4-million-square-foot complex that will include an exhibition hall, four new ballrooms, and a range of meeting spaces when complete. Fentress Architects collaborated with Arquitectonica on an undulating exterior envelope inspired by the curves of waves, manta rays, and coral reefs.
 
The facade consists of more than 500 angled “fins” constructed out of aluminum plates. Each fin is braced back structure-side and stainless steel struts tie them together to combat lateral loads from hurricanes as well as to account for acoustical vibrations. Behind the rolling facade, the building is clad in a high performance unitized curtain wall with a .23 solar heat gain coefficient. A structural steel backup with an aluminum enclosure supports the cantilevered fins every 15 feet along the curtain wall. Fentress and Arquitectonica worked closely with the fabricator to guarantee the undulating facade they had designed would be constructible. Using a combination of spline-based modeling, BIM, and careful construction drawings, the team made the fabrication and installation process seamless, architect to manufacturer. The fins act as a brise soleil and shade the glazing and interior spaces behind them at both the east and west entryways. At one particular moment on the east facade, they cantilever out an impressive 38 feet to create an exterior cover at the entry. The underside of each gap between the fins is glazed with a five-foot by ten-foot sheet of glass that slopes back towards a gutter for drainage. Each piece of glass was cold bent into place on site due to the double-curved surface it needed to achieve. While the project team embraced the shade that the fins provide as an added benefit, they did not design the facade for energy efficiency. After the team ran models to analyze the building’s performance, it became clear that the design was conceived more intuitively rather than for the sake of optimization. This allowed the decisions on fin spacing and geometry to be primarily aesthetics-driven while still providing natural shading.

SHoP Architects adds aluminum luster to Nassau Coliseum

Originally opened in 1972, the old Nassau Veterans Memorial Coliseum on New York's Long Island was given a facelift and interior renovation by SHoP and Gensler respectively in 2015.  SHoP’s team relied on the concrete massing of the 1970s structure to shape a new facade composed of over 4,700 brushed aluminum fins that wrap the building in broad sweeping curves. The project, which benefitted from a rigorous digitally-conceived workflow, delivered the new undulating facade geometry by precisely varying each of the fins in profile and dimension. Two primary fin shapes are designed from one sheet of aluminum composite material (ACM), minimizing waste while highlighting SHoP’s commitment to a design process that is tightly integrated with fabrication and assembly processes. John Cerone, associate principal at SHoP, told AN that one of the successes of the project is the new facade's reflective effects that pick up on colors of the surrounding landscape. This is especially evident during sporting events where crowds wearing the home team’s colors reflect onto the facade. The project in many ways mirrors SHoP's success with Barclays Center over five years ago—same client, same building type, similar design process. When asked what, in this project, arose as a surprise or a challenge to the design team working on Nassau, Cerone candidly said, "Nothing!" He elaborated, "As we continue these projects, it's a continuous iteration: We recycle process. I don't think this industry does enough of that." "Don't ignore fabrication constraints and input from contractors," Cerone said. The fins are planar and negotiate a ruled digital surface, which was informed by early feedback from fabricators and contractors. "An intelligence builds from doing other projects like this. While the componentry and hardware differ, the actual process of how you structure the model and develop methods of automation improves with experience." The architects cite simple definitions which they adopted and advanced from prior projects which help to automate the generation of parts for geometrically complex assemblies. "This to us was a proof. It's a great testament to not being surprised by the process," Cerone said. The design process for SHoP was initiated with a laser scan of the existing arena, resulting in a highly detailed topographic mesh surface that became the base geometry for forthcoming design and fabrication models. The framework of the new skin was designed as a long-span space frame, springing off massive existing concrete piers that were, in the words of Cerone, impressively over-structured. The resulting structural subframe was assembled on the plaza level of the stadium and craned into place. Only 32 “mega-panels” were required. "Facades are the closest you can get to manufacturing in architecture," Cerone said, "but we are looking towards using this process throughout the building. How can it inform the superstructure and the interior? We are working to scale this process up."

The Missouri Innovation Campus ripples with an angled aluminum skin

facadeplus_logo1
Brought to you with support from a> ->
The Summit Technology Academy of the Missouri Innovation Campus, designed by Gould Evans and DLR Group, is a new education facility focused on bridging the gap between the workplace and the classroom. The building houses an innovative educational program developed by the University of Central Missouri, the local Lee’s Summit School District, and area industry participants. The collaborative nature of the program inspired the design team when planning the building’s facade.

  • Architects Gould Evans (design architect), DLR Group (architect of record)

  • Location Lee’s Summit, MO
  • Date of Completion 2017
  • System Metal rainscreen
  • Products Custom metal façade by Standard Sheet Metal over Green Girts support system, Midwest Masonry burnished CMU, Kawneer curtain wall
There are three primary systems on the facade. The majority of the building is clad with a custom-fabricated metal panel rainscreen across the second and third levels and a curtain wall glazing system between the metal panels. The first level is clad with burnished concrete masonry units and punched windows. In an interview, Sean Zaudke, associate principal at Gould Evans and member of the design team, told AN“We wanted the facade system to be something that was innovative and simple; something that was very specific to the project.” The metal panel facade was fabricated from standard anodized aluminum coil stock, which was bent diagonally at two locations on each panel. There was only one panel type, which was rotated and mirrored across the building envelope to create a rippling effect that responds to light in different ways. Each panel is ten feet long and two feet wide with a return at the edge so they lock into each other. The dimensions of the aluminum coil stock govern the height of the skin, so the metal facade is twenty-feet in elevation. The metal is a rain-screen system attached to a continuous insulation barrier with a horizontal girt system. At the very beginning of the project, Gould Evans was working with Standard Sheet Metal on the design of the panels. The team started with a series of paper mockup iterations to test different strategies to discover the most efficient panel design. The biggest challenge was maintaining a rectilinear edge while introducing two angular bends. After arriving at a solution, the project team worked with the metal fabricators to optimize the design. At the point where the facade meets the sky, the metal panels are met with custom bent closure panels. These close the building envelope at the back while maintaining its undulating profile. A simpler flat closure panel meets the bottom of the rain-screen system. Additionally, simple metal returns negotiate the joint between the complexity of the bent edge and the straightness of the glass curtain wall. Gould Evans designed the interior to be a flexible, adaptable space so that walls can move to respond to programmatic changes. The design of the curtain wall is adaptable in much the same way. Every piece of the curtain wall integrated into the rainscreen system is the same two-panel module and can be added, removed, or relocated. The system can be adapted as the needs of the educational program evolve.

The project, dubbed 'EarthCampus', involves an extensive renovation to an existing 26,000 square-foot cement block building housing technology and manufacturing divisions, along with the addition of a new entryway, connecting atrium, and office workplace. Key features of the project include an uplit translucent aluminum facade. The architecturally stabilized aluminum foam panels were added to the existing office building, installed on a subframe that mechanically attached to the existing block wall. The lightweight panels, manufactured by Alusion, were produced by injecting air into a molten aluminum liquid that contained a fine dispersion of ceramic particles. These particles stabilize the bubbles formed by the air, resulting in a porous but strong surface. The sheets are manufactured in custom sizes, but also are commercially available in standard four-by-eight-foot sheets. The textural aluminum panels frame an entryway pavilion housing a 25-foot-tall LED video wall that showcases live EarthCam feeds from around the world and leans over the interior of the room. This surface extends beyond a curtain wall enclosure where it is clad with flush metal panels, precisely tapering to a sharp edge. “We wanted the building’s facade, one of the first things a visitor sees, to reflect our company values. At the top of the list are innovation and transparency,” said Bill Sharp, senior vice president at EarthCam. “We apply these principles in our business practices, products, services and relationships with clients and employees. The entry is made of three stories of transparent glass where visitors can view from both inside and out a floor-to-ceiling video wall featuring our live streaming camera feeds and construction time-lapse movies.” A steel-clad tunnel leads visitors to the new 11,000 square foot employee workplace where floor-to-ceiling windows and skylights offer ample daylighting. The workplace environment prioritizes a strong connection to nature and the art housed both within the building and throughout the campus grounds. Energy efficiency targets were achieved through the integration of sustainable equipment. Reclaimed building components and new materials made from recycled content contributed to the LEED certification of the facility, highlighting EarthCam’s commitment to corporate sustainability.

At Arizona State University, pixelated aluminum louvers shade residence hall

facadeplus_logo1
Brought to you with support from ->
The newest residence hall at Arizona State University in Tempe, the Tooker House, creates an impactful addition to the campus while addressing the intense solar radiation in Arizona. Solomon Cordwell Buenz’s (SCB) design consists of two parallel masses running east to west and interlocking diagonally in the middle. While the building has an expansive south-facing facade, the project mitigates solar radiation through multiple approaches.

  • System Perforated aluminum louvers with vertically suspended truss, perforated aluminum screen, sandstone panels
  • Products Custom fabricated perforated aluminum screen and louvers, custom fabricated sandstone panels with aluminum window surrounds, Kingspan metal panels, Dryvit exterior EIFS
There are two primary facade systems at work on the southern-facing portion of the residence hall. The first is a system of perforated aluminum vertical louvers. The second system is a sandstone panel facade with punched aluminum windows. The remaining portions of the building are clad with insulated metal panels and perforated aluminum screens that link the building’s massings together. SCB chose a material palette which was reflective of the surrounding desert context. Due to Tempe’s climate, the solar shading strategies were particularly important in the design approach. SCB conducted an intensive sun shading analysis on all facade exposures. The goal was to create a facade which achieved a 20-25% reduction of solar heat gain and offered visual transparency to the student rooms behind. The perforated aluminum louver system wraps one portion of the south facade in an intricately textured design. The louvers are spaced twenty-two-inches apart on center on the south facades, with a more generous spacing on the  southeast-facing side. The louvers are then attached to a vertically suspended steel truss anchored into steel plates embedded in the concrete structure. A drainable exterior insulation finishing system (EIFS) is applied to the concrete as a backdrop to the aluminum louvers. Each louver has a unique rotation which results in an pixelated pattern stretching across the three continuous facades. Every louver’s angle of rotation is set with screws and required coordination with the subcontractor to achieve the specific angle. As seen in the diagrams, when viewed as a whole, the facade emulates the waves of sand dunes and other natural patterns contextual to the region. In coordination with the facade manufacturer, Kovach Building Enclosures, the project team analyzed different louver shapes and monitored overall effectiveness and design aesthetics but also worked to make sure the design was cost efficient. The louvers ended up with a unique “airfoil” shape which softens their visual profile, opening up the facade to increased daylighting and views of the campus. The material transitions to sandstone on the eastern portion of the south facade, and provides a change in scale in opposition to the louvers. It also delineates the dining hall program on the first level. The facade contains punched windows with aluminum surrounds extruded out, effectively creating external solar shading devices. Additionally, perforated aluminum cladding on stairs, bridges and terraces provides extra solar protection while maintaining ventilation in the open air spaces.

  • Products MARIANItech 200x64x20mm rhomboidal expanded aluminum mesh with gray powder-coat finish
The facade consists of a glass curtain wall on the ground floor and, on the upper floor, an expanded metal screen mounted to the concrete structure. This stratification is meant to open up the first level as a public space and transition to privacy in the second level office spaces while still providing light permeation. The metal screen is an aluminum expanded metal rhomboidal mesh where the size of each rhomboid is 200 by 64 by 20 millimeters (7.87 by 2.51 by 0.78 inches). The metal is given a gray powder-coat finish to reflect the sun off of the building and to protect it from weathering. The rhomboid apertures are fabricated at an angle to create a brise-soleil, blocking sunlight during the hottest days of the year and allowing the sun to penetrate the facade during the winter. The intent was to create the perception of a solid building within its urban context without ever sacrificing access to daylight and surrounding views. The screen continues over all windows in the facade above the first floor. On the interior, it makes itself present through the patterns it creates in the glass partitions’ reflections and the shadows projected onto the walls, floors and ceilings. The material is visually drawn through the building envelope toward the interior and extends the implied connection between the inside and the outside. The same aluminum screen, powder-coated with a darker color, is used on an adjacent fence, creating a visual layering effect which emphasizes the material and its inherent pattern. VoipVoice Headquarters (Courtesy Medulla Studio) LDA.iMdA said in a statement that the purpose of the metal facade is “to create views over the surrounding hills and landscape and, at the same time, curate a perfect link between light, material, and shadows so that it can produce feelings of wonder in people who use the workspace.”

AIA speaks out against Trump’s proposed steel and aluminum tariffs

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.”
