New York’s SHoP Architects has created proprietary technology that is making it easier for them to organize materials during construction. During the construction of the Barclays Center from 2008 to 2012, the firm developed a novel iPhone interface capable of scanning facade components during fabrication, assembly, transport, and installation to keep an up-to-date digital catalog of the status of construction. Now, the firm is applying this comprehensive platform to the construction of its Innovation Hub located in Gaborone, Botswana, where on-site contractors can effortlessly scan recently installed items while checking in on the overall progress of the project.
The Botswana Innovation Hub is an ambitious project. The 310,000-square-foot facility is set to be the country’s first LEED-certified building, and environmental performance is significantly impacted by the structure’s complex assembly. SHoP designed an “Energy Blanket” roofscape, which incorporates large overhangs to shade interior spaces and collect rainwater for re-use. Photovoltaic panels are placed across the roofscape to further boost environmental performance.
The project’s complexity is further heightened by the incorporation of an undulating facade that projects off and indents the structural system. SHoP’s mobile interface plays an essential role in the project’s logistics and construction. The application labels each element—i.e AA2000—and the number of identical units. Each unit type is assigned to a specific construction crew that tracks the units in a database throughout assembly.
The interface has come a long way since its inception a decade ago. Initially a stitching together of off-the-shelf software applications commonly used by architects and contractors (Autodesk, NavisWorks, Filemaker), SHoP Architects has rewritten the code in-house, which allows for more seamless and scalable linking and visualization of 3-D models to live data. Why is this significant? SHoP can now take a holistic portfolio approach to track projects from earlier phases. In the next year, SHoP Architects hopes to implement its mobile interface across all of its projects.
How It WorksWhat makes the Matterport platform unique is its simplicity and efficiency. Scanning a room in 3-D previously required trained technicians and complicated software that took countless hours to capture and process. Matterport has simplified the experience by creating its Capture app for iPad that allows users to operate its 3-D camera with the push of a single button, which takes just 20 to 30 seconds per scan (total time to document an entire building depends on the size). Once the space has been captured, users can upload the data to Matterport, which processes and hosts the files for sharing within a matter of hours, Chwalibog says. The Pro2 camera generates high-quality 4K, 2-D photography in addition to state-of-the-art 3-D and VR walkthroughs and floorplans all from one device. The software and cloud services work together to capture and automatically weave together thousands of digital 3-D images into an accurate, immersive photorealistic model that can be shared, annotated, and exported to a variety of tools such as Autodesk ReCap or Revit, improving efficiency and collaboration on the front-end of the project. Additionally, Matterport adds value to the entire building lifecycle, including construction documentation and maintenance. Chwalibog notes that on the job site, project team members use the technology to record milestones, such as when structural steel, foundation work, rough walls, plumbing, mechanical, electrical, or plumbing are in place. “What you end up with is a series of three-dimensional models of particular moments in time during that construction process, so it meets the needs of construction documentation to actually document what was built,” he said. “I can identify any changes from what was actually built versus the design intent, so now I can proactively make some decisions about how that’s going to impact the next milestone.” Likewise, Chwalibog says the three-dimensional record of the project gives property owners much better intelligence about existing conditions which can prove invaluable years later if or when a renovation takes place.
Competition winner uses composite materials to re-imagine Semper's primitive hut.The title of TEX-FAB's fourth annual competition—Plasticity—has a double meaning. It refers first to the concept at the core of the competition brief: the capacity of parametric design and digital fabrication to manifest new formal possibilities. But it also alludes to the material itself, fiber-reinforced polymer (FRP). “Plastics have the potential to push contemporary architecture beyond the frame-plus-cladding formula dominant since at least the 19th century,” said competition winner Justin Diles. Pointing to traditional stonecutting and vault work, he said, "I'm very interested in this large volumetric mode of construction, but I'm not at all interested in the stone. I think that composites probably offer the best way of addressing this old yet new mode of constructing architecture." Diles' proposal, Plastic Stereotomy, builds on his work as a KSA fellow at The Ohio State University. But where his earlier Eigenforms were two-dimensional freestanding walls, Diles' Plastic Stereotomy pavilion—which he will build at scale during the coming months—is fully three-dimensional. Inspired by teaching tools designed by Robert le Ricolais, Diles used a finite element analysis 3D modeling plugin to simulate surface buckling by superimposing volumes onto one another. "Those pieces are voluptuous; they create a lot of poché [thickness] as they overlap with one another," Diles observed. While the plugin developed by his friend was critical to the design process, Diles remained focused throughout on the end goal of fabrication. "What I'm really looking at is how we can use simulation to think about issues of construction rather than just optimization," he said. Custom fabrication shop Kreysler & Associates will provide technical support as Diles moves from design to construction. Diles cites the fire-resistant FRP cladding developed by Kreysler for Snøhetta's SFMOMA as an example of how composite materials can ease the transition from two-dimensional to volumetric design. "Even though the project still adheres to Gottfried Semper's model of a lightweight frame and cladding, the panels don't have a frame expression," he said. "They're massive, with ripples and indentations. They point to a new way of thinking about architectural surface and enclosure." Kreysler and Diles will work together to streamline the techniques he used to build his competition prototype, a scaled-down section of the Plastic Stereotomy pavilion. (Bollinger + Grohmann will provide additional structural and material engineering support.) For the mockup, Diles used a 5-axis CNC mill to shape EPS foam molds onto which he layered up FRP cloth. He then removed the pieces from the molds, painted them, and glued and bolted them together, adding stiffeners to the open-backed components. Because the FRP is so light, he used two solid foam blocks to weigh down the structure. "I'm interested in working with Kreysler around thinking through production to make it more efficient," said Diles. For the fabricators, the TEX-FAB collaboration represents another step in Kreysler's journey from boat-building to other applications of composite materials, including architecture. "We're excited to work on this with Justin," said Kreysler's Josh Zabel. "It's exciting to see designers put fresh eyes on these materials we're devoted to." Plastic Stereotomy will be on display at TEX-FAB 2015 Houston at the University of Houston College of Architecture, March 26-29. The conference will feature workshops, lectures, and an exhibition on the theme of Plasticity.

A new modeling program can give any material a makeover.TUFTIT is a fabrication program developed by Alexander Josephson and Pooya Baktash, two students who put their studies at the Architectural Association in London on hold to found Partisans, a research-based architectural platform they started in Toronto following the financial meltdown in 2010. What seemed like a risky venture at the time might just be Josephson and Baktash's best career move, especially if TUFTIT is an indication of the kind of technologically innovative projects they're executing. The modeling program was born from a desire to reinterpret popular traditional styles, like "Edwardian tufted leather furniture" featured in a Restoration Hardware catalogue, for a contemporary audience. "To us, this was an apt example of where innovation and reinvention could occur, especially with the use of parametric modeling," said Josephson. "The goal was to create a radical new interpretation of that model, one that was completely organic and free in its scale and use." The program makes it possible for any surface to be milled with the tufted look of soft leather or fabric-covered furniture, such as marble, wood, plastic and foam in sizes ranging from a single stool, an eight-foot-long day bed (pictured here) or, potentially, the facade of an entire building. Partisan's goal is not to create a specific object, but to develop a formal language that can be applied as easily to a chair as to a concrete facade. The programming of the script enables a high level of precision from micro to macro, with the added benefit of manually sculpting the form for custom jobs. "It starts with a hexagonal point grid which is deformed in parallel with the seat depressions," Jospehson explained. "A Voronoi algorithm is applied to this grid, leaving a free flowing set of 3D curves. The button dips come next, some of which extrude through the piece, leaving holes for ventilation or for drainage in outdoor situations. The surface patterns can be rotated, mirrored, or cut to create continuity between any tiled modules. " Once the program has been scripted in Rhino, Partisans takes it to a CNC fabricator, in this case Tim Sheppard, President of Styropatterns, a Toronto-based polystyrene pattern manufacturer specializing in large CNC milled patterns. Once the piece has been milled, Josephson and Baktash make a silicon mold in their model-making studio in order to cast multiples of the form in materials ranging from plaster to resin and concrete. They then finish each piece by hand, according to client specifications. "A client asked me recently if I would have a problem creating softer edges at the legs to a bench we are doing," said Josephson. "That’s no problem at all. It's the language that seems to be the only thing that's really designed. The specific details of any given piece regarding size or edge are left intentionally open to interpretation. We like the idea of mass customization and as a result each piece can ostensibly be quite unique."
