The Lone Tree Pedestrian Bridge shares the name of the Colorado city it rises in and connects Lone Tree’s south and north sides. More than a bridge, Denver’s Fentress Architects imagined the anchoring structure as an instantly recognizable icon, and drew upon the city’s leaf emblem to create a distinctive 80-foot-tall, 100-ton white steel pylon. The 170-foot-long pedestrian bridge crosses the city’s busiest street, Lincoln Avenue, and is supported by six cables that branch off from the “leaf,” creating an effect reminiscent of Santiago Calatrava’s elegant cable-stay infrastructure projects. The bridge itself is surrounded with an open metal mesh and is topped with an ETFE canopy to protect pedestrians from the weather while still allowing sunlight to pass through. Soft lighting was also installed to allow for the structure’s use at night. Access to the pylon and bridge is accomplished by a series of spiraling ramps on both sides. The project was especially important for the community, according to Fentress, because although 90,000 cars pass through Lincoln Avenue daily, there had previously been no way for residents to easily cross the major arterial. The project was completed in June 2018 and now occupies a previously unfilled roll in connecting biking and walking trails throughout the Denver Metro area. Earlier this week on September 10, the Lone Tree Pedestrian Bridge was named a recipient of the Chicago Athenaeum’s 2019 American Architecture Awards. All of the winners will be honored at an awards gala on October 10.

Brought to you with support fromThe Denver Art Museum is undergoing a significant expansion and overhaul led by design architect Machado Silvetti and architect-of-record Fentress Architects. The project includes the restoration of Gio Ponti’s glass tile-clad North Building and the construction of an entirely new, elliptical-shaped welcome center defined by a scalloped structural glass curtainwall. The site of the welcome center is not lacking in significant neighbors: Studio Libeskind’s expansion to the Denver Art Museum is located to the south, Michael Graves' addition to the Denver Central Library lies to the east, and Gio Ponti’s North Building to the northwest.
Denver Art Museum, "the primary objectives of the Denver Art Museum welcome center included creating a structure and spaces that would bring two very distinct, but disparate, buildings together to function as a true campus; to act as a counterbalance to the opaque, dense buildings we had built to house the artwork; and to serve as a beacon within the city that felt inviting and welcoming to all." A challenge for the design team was translating the civic ambitions of the client, and the cultural role of the museum within the region, into a facade strategy with a distinct identity that highlighted its surroundings without the visual hinderance of exposed fasteners and vertical mullions. For Machado Silvetti Principal Jeffry Burchard, “once this design concept was in place, the design team then went through many rounds of conversations with fabricators and installers in the process of realizing that full height curved IGUs, supported off of triple laminated glass fins connected to the second-floor cantilever was not only possible but the best and most efficient way to implement the concept.” In total, 52 glass panels enclose the welcome center. The panels have a universal width of 8 feet and a curve radius of 10 feet. Panel heights differ according to location; approximately two-thirds of the panels are 25-feet tall while those located along the clerestory are 5-feet tall. To install the panels—the majority of which weigh 3,200 pounds—the installation team relied on a suction cup lifter with articulated mounts that conformed to the curved surfaces of the panels. The panels were hoisted by a team of eight and mounted onto the custom-fabricated facade system. “Each curved glass unit is supported at the top and bottom by a curved stainless-steel angle. These angles are supported by custom stainless-steel fittings that attach to triple-laminated, low-iron glass fins using stainless-steel bolts through holes drilled in the glass fins,” said Fentress Architects Principal and Director of Technical Design Ned Kirschbaum. “The glass fins are in turn point‑supported top and bottom with stainless steel bolts through drilled holes in the glass fins and connected back to the building’s primary steel structure through custom stainless-steel fittings.” The $150-million project includes a significant overhaul of Gio Ponti's castellated North Building, also led by Fentress Architects and Machado Silvetti. A significant component of the museum's overhaul is the repair of the building's facade, which is comprised of approximately one million glass tiles placed atop a concrete structure. Additionally, the design team will complete a roof terrace originally planed by Ponti but left incomplete due to budgetary constraints. Interior work includes a revamp of exhibition spaces as well as a new entrance. Denver Art Museum Deputy Director Andrea Kalivas Fulton, Machado Silvetti Principal Stephanie Randazzo Dwyer, and Fentress Architects Technical Design Director Ned Kirschbaum, will be joining the panel "Facade Strategies for Curatorial Institutions" at The Architect's Newspaper's upcoming Facades+ Denver conference on September 12.According to Andrea Kalivas Fulton, Deputy Director of the
In November 2018, news first broke of the five-firm shortlist competing to design the $8.7 billion Terminal 2 at Chicago’s O’Hare International Airport. The star-studded list held both international and local firms, and today, Chicago city officials have made public designs for each team’s proposal. Chicagoans and frequent fliers have until January 23 to vote for their favorite designs and offer feedback, here. The O’Hare 21 expansion, which will expand O’Hare from 5.5 million square feet to 8.9 million square feet, is a pet project of outgoing mayor Rahm Emanuel. O’Hare currently serves nearly 80 million travelers a year, and with demand projected to grow, the extant Terminal 2 (built in 1963) needs to be expanded. The team of Colorado’s Fentress Architects, engineering and architecture firm EXP, Brook Architecture, and Garza Architects have proposed an undulating terminal with a ribbon-like canopy, held up by slender, full-length columns. A split in the terminal’s massing would allow natural light into the center of the building, a necessity given that the team has stacked more floors into its terminal than the other four. Foster + Partners has been working with local firms Epstein and JGMA, and have produced a dramatically curved, cave-like terminal fronted by an enormous wall of glass. Foster’s terminal resembles a draped piece of fabric swaying in the wind that splits into three separate arched halls at the rear but opens to what they’ve dubbed a “theater of aviation” at the tarmac. The use of a crisscrossing truss system topped with glass creates a coffered ceiling effect while also allowing in natural light. From the renderings, it appears that the terminal’s interior will be clad in a warm wood finish. Studio ORD Joint Venture Partners, the team formed by Chicago’s Studio Gang, Corgan Associates, Solomon Cordwell Buenz, and STL Architects, was heavily influenced by themes of convergence and confluence. Three curves join in the middle to carve out space for a massive central skylight. The roof of each curve, formed from ribs that extend into the terminal’s interior, tent in the center; it appears the underside of each will be clad in timber. The team has described their proposal as one that’s layered but easy to navigate. Skidmore, Owings & Merrill (SOM), who have partnered with Ross Barney Architects and Arup, are proposing ORD, from a shortening of Orchard Field, the original name of O’Hare (unrelated to Studio ORD above). Although their plan is squarer than the others, the SOM team has also designed an undulating roof supported by coffered timber trusses. The roof would cantilever out over the terminal’s tall glass walls, and according to the video, ample landscaping that references Illinois’s nickname as “the Prairie State.” Intriguingly, the terminal would also include enclosed outdoor plazas, complete with tree-strung hammocks, for passengers to relax in. Last but certainly not least, Santiago Calatrava and local firm HKS have presented the most ambitious of the five proposals (though it fits quite snugly within Calatrava’s oeuvre). Resembling a ship’s prow, the glass facade bulges in the center before terminating at a sharp point. Inside, large, unbroken spans are supported by Calatrava’s signature structural “ribs” to create a soaring interior space. The team has also proposed turning the existing parking area to the terminal’s rear into a landscaped “hotel, retail, and business complex,” though there’s no telling how much that would add to the budget. The city and Chicago Department of Aviation are being pushed to make a decision before Mayor Emanuel departs in May of this year, and the project is expected to finish in 2026. Models of each team’s submission can be viewed at the Chicago Architecture Center until January 31, and Terminal 2 will be displaying the new designs digitally until the 31st as well.
Colorado's Fentress Architects has released a first look at the U.S.’s pavilion for the upcoming Expo 2020 Dubai, revealing renderings of its mobility-themed, coliseum-like installation. Under a theme of “What Moves You? The Spirit of Mobility,” Fentress and partners from the U.S. State Department, George P. Johnson Experiential Marketing (which is designing the pavilion’s “experiences”), and various public and private partners from the United Arab Emirates revealed the pavilion’s final design on November 28, 2018. The cylindrical National Pavilion will be set askew with structural slants to convey a sense of movement and wrapped in a dynamic facade that can double as a screen for American-themed background imagery. According to Curtis Fentress, a founding partner at Fentress Architects:
We’re looking at an Expo that is related to mobility, movement, travel, sustainability—things that are very important to the world today. We have designed this building to be circular in form with slants fashioned to project a sensation of movement, making the viewer feel like the building itself is in motion. And then, once you enter the building, it opens up to what the United States stands for: We are an open, accessible country where you can live to create ideas. It showcases all the things we are doing in America: developing technology and concepts that are going to move us forward in the future. Designing this pavilion is a tremendous responsibility—one we take very seriously—as we will be showcasing America and American ideas to over 25 million people expected to visit the Expo.Pavilion USA 2020, the collective entity responsible for the installation, also announced a partnership with the California-based Virgin Hyperloop One. Come 2020, the pavilion will host mock-ups of Virgin’s hyperloop pods and offer simulated rides ahead of a projected 2021 rollout in as-of-yet unfinalized locations. The three-story pavilion will feature an internal walkway wound around a central internal void and multi-media column that will double as a triple-height public plaza. The programming will explore a range of what “movement” can mean, from space travel, to shipping cargo, to tracking the flow of blood throughout a body. The Dubai 2020 Expo will open to the public on October 20, 2020, and run through April 10, 2021.
Five finalists have been selected in the competition to design the new $8.7 billion expansion of Chicago’s O’Hare International Airport, narrowing the field from the longlist of 12 released in September. The shortlist features a mix of local names and international studios: Skidmore, Owings & Merrill (SOM), Santiago Calatrava, Foster + Partners, Chicago’s own Studio Gang, and Colorado’s Fentress Architects. The expansion, part of a modernization initiative dubbed O’Hare 21 by outgoing mayor Rahm Emanuel, will totally replace the V-shaped Terminal 2, a holdover from the airport’s opening in 1944. O’Hare is one of the busiest airports in the world and currently services nearly 80 million passengers a year, and O’Hare 21 will expand the airport’s footprint from 5.5 million square feet to 8.9 million square feet. Such a large project means that these teams likely won’t be going it alone. Fentress is joined by Brook Architecture, Garza Architects, and engineering and architecture firm EXP, Calatrava will be working with local firm HKS, while Foster + Partners has teamed up with local firms Epstein and JGMA, and Studio Gang has partnered with Corgan Associates, Solomon Cordwell Buenz, and STL Architects. SOM will also be joined by Ross Barney Architects and Arup in their bid. After a review by the Department of Aviation, one team will be chosen to design the Terminal 2–replacing O’Hare Global Terminal, while a second will be tapped to design the airport’s two new satellite concourses. Perhaps what’s most interesting is who didn’t make the cut. BIG was knocked out, as were HOK and Gensler. Even Helmut Jahn, a Chicago wunderkind who designed O’Hare’s Terminal 1 in 1986, wasn’t chosen. Now that the shortlist has been chosen, an official selection committee of business, civic, and transportation leaders from Chicago will choose who ultimately gets to design the new facilities (with local architecture firms and cultural institutions providing technical support). Mayor Emanuel is pushing the city to choose before he leaves in May of 2019, and if all goes as planned, the multi-phase O’Hare 21 should be complete by 2026.

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.
Fentress Architects will design the United States of America’s pavilion at World Expo 2020 in Dubai. The winning design is based on the theme “What Moves You,” and will emphasize, “the power and diversity of culture, technological innovation in mobility, and commercial opportunity throughout the United States,” according to a statement from Pavilion USA 2020. Fentress’s design will play into the “dynamism of American culture,” and national values of “ingenuity, progress, and innovation.” The renderings from Fentress are yet to be released. “Working across the U.S. has given Fentress Architects diverse perspective on the attributes and attitudes that Americans share. We will coalesce these characteristics into a single architectural expression at World Expo 2020 Dubai, representing the entirety of the U.S. and its design prowess to an international audience,” said Curtis Fentress, principal in charge of design at Colorado-based Fentress Architects. The Fentress-designed pavilion will work with large and small firms from across the U.S., local citizens' groups from different states, and the U.S. and U.A.E. governments to tell a story about the U.S.’s role on the global stage. The exhibit and experience design will be curated by Michigan-based George P. Johnson Experience Marketing (GPJ). Dubai Expo will be held between October 20, 2020, and April 10, 2021, near Dubai emirate’s western border with Abu Dhabi emirate. American firm HOK is responsible for its master plan. The U.A.E. selected the theme “Connecting Minds, Creating the Future” and the sub-themes Sustainability, Mobility, and Opportunity. It is expected to draw over 25 million visitors to the city and be a major economic event. The Bureau International des Expositions is the organizing body behind the shows, which are held intermittently around the world, most recently in Milan in 2015 and Shanghai in 2010. Previous expositions have been occasions for spectacular, sometimes experimental architecture, as in Buckminster Fuller's dome for Expo 1967 Montreal and Kenzo Tange's pavilion for Expo 1970 Osaka. The shows have historically been venues for industries of various nations to showcase their abilities and visions. Expo 2020 is the first world expo held in the Middle East, North Africa or South Asia. The preparation and operation of the fair are expected to result in 277,000 new jobs in the U.A.E. and inject $40 billion into the local economy. Check out this link for more details.
The Denver Art Museum (DAM) has just received a major standalone financial gift in support of revitalizing the museum’s North Building. The iconic Gio Ponti-designed North Building will celebrate its 50th anniversary in 2021 with $150 million in expanded galleries, site upgrades, and expanded resources for youth programs. The $25 million gift came from Museum Board Chairman J. Landis Martin and his wife, Sharon Martin. When upgrades are complete the North Building will bear their name in honor of their gift. “The North Building is considered one of the most significant objects in the Museum’s collection, and our family is honored to support the much-needed rehabilitation required to bring it into the 21st century,” said Lanny Martin at a ceremony announcing the gift. “The Denver Art Museum is a beacon of creativity, representing the incredible depth of the cultural community in our region and it is critical that we continue to invest in it for the benefit of the entire community.” The North building is the only Gio Ponti building in North America and was designed in collaboration with Denver-based James Sudler Associates in 1971. The improvements to the building will include bringing the public to a seventh-story observation area, part of the original design that was never realized. A new welcome center will also unify the museum campus, which also includes a wing designed by Danial Libeskind. The project was master planned by Tryba Architects in 2015. Formal designs have been led by Denver-based Fentress Architects with Boston-based Machado Silvetti Architects. The plan is to complete the upgrades and additions to the museum by 2021.
LAX finally opened its shiny new Tom Bradley terminal, designed by Fentress Architects, to quite a hullabaloo in July. The throngs who showed up for “Appreciation Days” got to enjoy shopping, music, and even free LAX keychains and knickknacks. But one of the most prominent elements was missing: the public art. Major pieces by Ball-Nogues, Pae White, and Mark Bradford were all delayed for what one participant called “a lack of sophistication on LAX’s part” in shepherding such work through. In other words, the officials didn’t get how to pull this kind of thing off. Well never fear, despite the bumps, contract disputes, and many miscues, the installations will begin opening in late September and continue through the end of the year. Better late than never.
Don't look now, but LAX—the airport everyone loves to hate—is starting to complete its major makeover. The biggest change is the brand new $1.9 billion (yes, billion) addition to the Tom Bradley International Terminal, designed by Fentress Architects and unveiled in 2008. Its curving roofline, emulating waves breaking on the nearby beach, pops up behind the original Tom Bradley structure, which itself was recently renovated (for the cost of $723 million) by Leo A Daly. Inside, the soaring new terminal is comprised of echoing arches and massive vaults forming a 110-foot-tall Great Hall, which beams natural light through large windows and clerestories. The terminal also includes 150,000 square feet of new retail and dining. The entire new facility, including large new concourses, security facilities, light wells, and more retail, measures 1.2 million square feet, which doubles the space of the existing Tom Bradley terminal. This is just the tip of the iceberg. LAX's overall Capital Improvements Program budget is—wait for it—$4.1 billion, including a new Central Utility Plant, additional terminal renovations, and restoration of the Theme Building. Perhaps the most noticeable change just opened last night: AECOM's new roadway enhancements, including new LED light ribbons above roadways, sculptural, Y-shaped light poles, and fancy new metallic canopies outside of Tom Bradley. Watch for more details in the next West Coast issue of The Architect's Newspaper.
