This robotic arm by a Swiss architecture firm stacks bricks into lightweight helixes for complex building facades
“The system explores the new dynamics of social creation and consumption—design, make and enjoy, allowing users to create to design their own cocktail creations while digitally controlled machines turn those creations into reality.” – Carlo Ratti
Architects update pre-Columbian building method with modern tools and materials.Matter Design's latest installation, Round Room (on display at MIT's Keller Gallery last fall) was born of a "marriage" between two of the firm's ongoing interests, explained co-founder Brandon Clifford. First, Clifford and partner Wes McGee had long hoped to work with Autoclaved Aerated Concrete (AAC). Clifford, moreover, had been impressed during a trip to Cuzco by the Incan wedge method of masonry construction, in which precisely-carved stones are aligned on their front face, then backfilled with mortar. "This seemed like a tremendously rational way of building," he said. "Ever since then we had been wanting to do a project that translates that process into digital design." With Round Room, designed and fabricated in cooperation with Quarra Stone, Matter Design did just that. Though inspired by pre-Columbian building practices, the installation firmly situates the wedge method in the digital age. Clifford and McGee began by building a rough prototype, a six-component section resembling a half-dome. "We knew that we were going to build something that was round," said Clifford. "Not a sphere, but something that has slow changes in geometry." By focusing on curved spaces, the designers were already pushing the limits of the wedge method, historically limited to two-dimensional applications. With information gleaned from their prototyping session—including the general dimensions of individual units—they worked through a series of models in Grasshopper and Kangaroo, leaning on calculations developed for an earlier project, La Voûte de LeFevre. Clifford and McGee also visited Quarra Stone's Wisconsin facility. The trip "allowed us to get a feeling for where they were going to have problems with the geometry, and make changes," said McGee. "We were able to step in as consultant with respect to applying their tools." Using a water-fed robotic arm, Quarra Stone cut the AAC components—no simple feat. "One critical translation from the Incan technique was the fact that the front edge aligns, but the backwards taper allows for mortar to be packed in," explained McGee. "[The blocks] are machined on five sides." Round Room's components were then shipped to Cambridge and assembled on site by a team of students, including Myung Duk Chung, Sixto Cordero, Patrick Evan Little, Chris Martin, Dave Miranowski, David Moses, Alexis Sablone, and Luisel Mayas. (Austin Smith also assisted throughout the project; Simpson Gumpertz & Heger acted as structural consultants.) The installation team placed the blocks, used scrapers to remove any excess AAC from the front (interior) edge, then piped plaster into the wedge-shaped gap on the back (exterior) side. "Though it was a digital fabrication process, the assembly was quite a craft," observed Clifford. The collaboration with Quarra Stone was a first for Matter Design, which had both designed and built all of its earlier projects. "It was beneficial for us to understand the nuances of what they had to deal with on a daily basis," said Clifford. In fact, the relationship was so successful that Clifford and McGee are continuing it, with a fellowship that will send two researchers to the Wisconsin fabricators. "It's an area we're going to continue working in pretty heavily," said McGee. "It's an opportunity to interrogate this information exchange between designers and fabricators at a higher level."
...he used a 6-axis robot arm located at the Robotic Fabrication Lab at Kent State. A hand welding extruder, called the Mini CS, was attached to the robot arm to serve as the 3D printhead, and it extrudes plastic material in a sort of FDM-style process. The technology, provided by Hapco Inc. and called BAK/DOHLE, is employed by universities, government agencies, and concerns like the University of Michigan, Oak Ridge Laboratory, the US Department of Energy, and the University of Tennessee.The pavilion debuted at Cleveland's Ingenuity Fest.
Rotterdam Centraal Station's relationship to the existing urban fabric called for different treatments of its north and south facades.To call the commission for a new central railway station in Rotterdam complicated would be an understatement. The project had multiple clients, including the city council and the railway company ProRail. The program was complex, encompassing the north and south station halls, train platforms, concourse, commercial space, offices, outdoor public space, and more. Finally, there was the station’s relationship to Rotterdam itself: while city leaders envisioned the south entrance as a monumental gateway to the city, the proximity of an historic neighborhood to the north necessitated a more temperate approach. Team CS, a collaboration among Benthem Crouwel Architekten, MVSA Meyer en Van Schooten Architecten, and West 8, achieved a balancing act with a multipart facade conceived over the project’s decade-long gestation. On the south, Rotterdam Centraal Station trumpets its presence with a swooping triangular stainless steel and glass entryway, while to the north a delicate glass-house exterior defers to the surrounding urban fabric. Team CS, which formed in response to the 2003 competition to design the station, began with a practical question: how should they cover the railroad tracks? Rotterdam Centraal Station serves Dutch Railways, the European High Speed Train network, and RandstadRail, the regional light rail system. Team CS wanted to enclose all of the tracks within a single structure, but they came up against two problems. First, the client team had budgeted for multiple freestanding shelters rather than a full roof. Second, this part of the project was designated a design-construct tender in which the winning contractor would have a high degree of control over the final design. To work around both issues, Team CS turned to an unusual source: agricultural buildings. “We started to come up with a project built from catalog materials, so efficient and so simple that any contractor would maybe think, ‘I’m going to build what they draw because then I can do a competition on being cheap, and then I don’t need to [reinvent] the wheel,’” explained West 8’s Geuze. For the spans, they chose prelaminated wood beams meant for barns and similar structures from GLC. They designed the five-acre roof as an oversized Venlo greenhouse. It comprises 30,000 laminated glass panels manufactured by Scheuten. Integrated solar cells, also provided by Scheuten, produce about one-third of the energy required to run Rotterdam Centraal Station’s escalators. The north facade of the station continues the glass house theme. “We [took] the roof and we pull[ed] it over to the facade and made the entire elevation out of that,” explained Geuze. “What is on the roof becomes vertically the same. In plan you see a zigzag sort of meandering facade.” By day, the glass reflects the nineteenth-century brick architecture characteristic of the Provenierswijk neighborhood in which the station is located. At night, the relatively modest entrance seems almost to fade into the sky, except for a slice of white LED lettering over the passenger portal. Rotterdam Centraal Station’s south facade, by contrast, is self consciously extroverted. The entryway, which spans 300 feet over the subway station, was given a “very sculptural identity,” said Geuze, with a triangular mouth framed by stainless steel panels. ME Construct welded the 30-foot-long panels one to another to create a non-permeable surface. Within the steel surround are horizontal glass panels (Scheuten) through which the vertical interior structural beams are visible. “This plays beautifully with the station because the roof makes a triangle. The horizontal and vertical lines are a beautiful composition within,” said Geuze. Two reminders of the 1957 central station, demolished to make way for the new iteration, make an appearance on the south facade. The first is the old station clock. The second is the historic sign, restored in LED. “They are in a beautiful font, blue neon letters,” said Geuze. “We put them very low on the facade, the letters. The font became a part of the identity.” While its preponderance of glass and stainless steel marks it as a contemporary creation, Rotterdam Centraal Station was inspired by historic precedents, like Los Angeles’ Union Station and the European railway stations of the 1800s. Geuze spoke of the interior’s warm material palette, including a rough wood ceiling by Verwol that bleeds onto the building’s south facade. “We thought we could learn a lot [from history] instead of making what is totally the [norm] today with granite from China,” he said. “We have to make a station which is part of this tradition of cathedrals, where the use and aging is relevant and interesting.”
A folly in a Rotterdam suburb draws on residents' complex relationship with the city.The residents of Carnisselande, a garden suburb in Barendrecht, the Netherlands, have a curious relationship with Rotterdam. Many of them work in the city, or are otherwise mentally and emotionally connected to it, yet they go home at night to a place that is physically and visually separate. When NEXT architects was tapped to build a folly on a hill in the new town, they seized on this apparent contradiction. “This suburb is completely hidden behind sound barriers, highways, totally disconnected from Rotterdam,” said NEXT director Marijn Schenk. “We discovered when you’re on top of the hill and jump, you can see Rotterdam. We said, ‘Can we make the jump into an art piece?’” NEXT designed The Elastic Perspective, a staircase based on the Möbius strip. “The idea of the impossible stair [is] you’re not able to continue your trip. At first it seems to be a continuous route, but once you’re up there, the path is flipping over,” explained Schenk. “That’s a reference to the feeling of the people living there.” To catch a glimpse of Rotterdam, users must turn their backs on Carnisselande. Yet while the view is in one sense the destination, the staircase ends where it started, in the reality of the garden suburb. NEXT began by experimenting with strips of paper and thin sheets of steel to form the staircase’s basic shape. The architects then turned to AutoCad, where they finalized the design before 3D printing a 1:200 scale model. NEXT worked with engineers at ABT throughout the process. They relied heavily on 3D design software, Schenk said, “because all the steel was sort of double-curved.” Mannen van Staal fabricated the staircase from seven steel panels custom-cut with a CNC machine, said project architect Joost Lemmens. They bent the plates, largely by hand, and assembled the entire structure in their factory, temporarily welding the pieces together. They then disassembled the structure for transport to the site, where the components were re-welded by hand and using a vacuum-cleaner-sized robot. Cor-ten was a practical choice on the one hand because the rust obscures the stitches used to reconnect the seven panels. In addition, said Schenk, “It’s weatherproof, and sustainable in the sense that we’re not using a toxic coating.” The choice of Cor-ten also holds aesthetic and cultural meaning. The orange of the staircase contrasts with the green of the hill. Plus, “it’s a material quite often used in artworks, so of course it refers to the work of Richard Serra [and others],” said Schenk. “I think in short what it’s about is the idea of making a jump, make people be able to make a jump to see the skyline of the city,” he concluded. “We’re using the Möbius strip to express the ambiguity of the people living there: feeling connected to Rotterdam but being somewhere else.”
