Amuneal Manufacturing fabricates a “breathing” sculpture for a North Carolina plaza.For a public plaza in downtown Chapel Hill, North Carolina, landscape architecture firm Mikyoung Kim Design designed a unique sculptural installation that doubles as a stormwater management system. The 70-foot linear form is centrally located to engage the town’s residents with a looped, 10-minute light show. A misting sequence, drawn from a subgrade cistern, emanates through the perforated metal skin of the sculpture, giving the impression that “Exhale” is actually a living, breathing object. The original concept for the piece incorporated hydrological elements of the site in an engaging and transparent way, but the form was less defined. Over the course of nine months, designer Mikyoung Kim said her team designed countless rock-like shapes from clay, carving each from the inside out to achieve a thin, amorphous shape that consistently collapsed in on itself. Then, one night at home, Kim had a breakthrough when her idling hands picked up a few sheets of trace paper in the early morning hours. “I started folding a piece of trace paper and kept folding, and folding,” she recalled. “It was yellow and easy and beautiful; I fell in love with that.” The sheets also helped Kim balance her aim for delicacy with function and helped define Exhale’s fan-like corrugation. Through a series of quarter-scale mockups and Rhino drawings, the team worked to refine the size of the sculpture’s perforations, a process Kim likened to “squinting to make it clearer.” There are more perforations on the top than on the bottom, giving the impression of a sturdy base with a lighter feeling above. Another challenge came in integrating the corrugated, perforated surface with a support structure. Parametric scripting helped Kim dictate where the perforations would fall in relation to the framing elements. Kim turned to long-time collaborator Amuneal Manufacturing to fabricate the design. Amuneal converted the drawing from Kim’s Rhino files to Solid Edge. Those files were used to laser cut the sheet’s trapezoidal geometry and perforations from marine-grade stainless steel sheets. Amuneal’s CEO, Adam Kamens, estimated that almost 50 sheets where welded together to create the final form. Radial corrugations were folded on a CNC press brake. Because Exhale was designed for a plaza that wasn’t perfectly flat, Amuneal executed as much pre-assembly in its Philadelphia facility as possible. Sheets as large as the bed of a truck were craned into place and welded together on site. Abrasive finishing smoothed over seams and connections. The curved, stainless steel sheets conceal an internal misting tube that releases vapor through a high-pressure spray, as well as color-changing LEDs. Kim’s favorite part of the design experience was watching public reception of her work, which was unveiled on a warm day in late spring. “The combination of all the elements created a reaction from Chapel Hill that was a pleasure to watch,” she told AN. “I watched kids engaging it immediately and it made all of the hard work worthwhile.”
Lake Shore Drive was originally designed as “a boulevard. It was a pleasure drive early on,’’ said Lee Crandell of the Active Transportation Alliance, among the 15 groups that helped to write the “Our Lakefront” plan.
“It’s slowly turned into a freeway,’’ Crandell said. “We want it to feel like a boulevard.’’Read the full conceptual plan here. Three public hearings are scheduled this week:
- Aug. 6, 6 - 8 p.m., Gill Park, 825 W. Sheridan Road, 3rd Floor
- Aug. 7, 6 - 8 p.m., Truman College, 1145 W. Wilson Avenue, Atrium
- Aug. 8, 6 - 8 p.m., Peggy Notebaert Nature Museum, 2430 N. Cannon Drive, South Gallery
The platform calls for separating transit from car traffic with bus-only lanes and other public transit enhancements, such as Bus Rapid Transit. BRT vehicles are often designed to look similar to light rail vehicles (this is why BRT is sometimes referred to as light rail with rubber wheels), and the drawing does intentionally leave it open to interpretation whether LSD could include something like BRT or light rail.
Seven design variations are applied across 17 custom wooden benches, fabricated by Mark Richey Woodworking.Sited above a vehicular tunnel and therefore bereft of old growth trees, the Plaza at Harvard University, with its aggregate porcelain paving and curvaceous, sculptural benches, stands in stark visual contrast to the school’s notably shady yard and north campus. Designed by Stoss Landscape Urbanism, the plaza serves as a multi-functional space for staff, students, and the local community. A large part of accomplishing this goal fell to the unique seating solution, a collection of custom-designed, wooden slat benches that aim to increase the function and user comfort of the public space. Some of the benches are meant for lounging with no back and a low seat height, while others are higher with full seat backs. Some twist in the manner of a Victorian tete-a-tete settee, while still others support a touchdown working posture. Stoss's design for the benches, sliced like a loaf of bread, was achieved in Rhino with a Grasshopper plugin. The parametric modeling tool was instrumental in defining the benches' complex geometries. "At every change, the curves meet two general sections so there's a morphology of that form work," said Erik Prince, an associate at Stoss who worked on the plaza. "The wooden slats are an incremental radial splay of the overall geometry so every rib has a unique angle to it." The design team produced a 3D model for each of the 17 benches. Since the benches were manufactured based on information contained in the digital files, a substantial portion of time was spent developing accurate models that could be extrapolated for the fabrication process. "It was a deep model, so even the smallest changes would cascade throughout the design," said Greg Porfido, chief operating officer at Mark Richey Woodworking, which fabricated the benches. Further intricacies of the manufacturing process came from the slight change in the angle of each rib to accomplish the complex twists and turns of unique forms. The centermost rib stands vertically erect, while those radiating out to either side increasingly angle outward along the length of each bench, culminating in as much as a 30 degree lean at each end. Mark Richey Woodworking fabricated the ribs on a 5-axis CNC mill. The sharp angles of the intersecting slats, which have parallel reveals, were achieved with mitered connections fixed with epoxy and mortise and tenon joints. Once fastened together as a "bread slice," they were laid over a metal substructure and screwed from beneath. Removable metal caps on both ends conceal drivers for LED base lighting, power and data hookups, and deliver a smooth, clean edge. Reflecting on the process of parametric design and fabrication, both Stoss Landscape Urbanism and Mark Richey Woodworking were in agreement about the success of the process and the outcome of the project. "It's a great way to communicate, but it requires a very collaborative approach," Porfido said. "The stakeholders have to have trust in the process; otherwise it doesn't work."
