In Aarhus, Denmark’s second largest city, a consortium of architects, engineers, and manufacturers are advancing the capabilities of concrete construction formwork and advanced design. This effort culminated in a recently unveiled 19-ton prototype dubbed Experiment R.
The project, led by the Aarhus School of Architecture, Odico Formwork Robotics, Aarhus Tech, concrete manufacturer Hi-Con, and Søren Jensen Consulting Engineers, tackles the waste associated with concrete formwork through the use of a novel robotic fabrication method.
How does this new method work and why is it potentially so disruptive? According to the Aarhus School of Architecture, formwork is easily the most expensive aspect of concrete construction, making up to three-quarters of the total cost of a concrete project. Significantly reducing waste associated with the formwork process and the molds themselves boosts environmental performance and the economic feasibility of complex concrete geometries.
The project's new apparatus consists of a heated and electrically powered wire rotating at a speed of approximately 160 feet per second around a carbon fiber frame. This device is mounted atop a robotic arm, which can shape complex detailing. While a polystyrene mold was used for the formwork of Experiment R, the mechanism has the capacity to cut through harder materials such as stone and timber.
Conventional methods of formwork fabrication are significantly more laborious—a typical CNC milling machine is able to process an 11-square-foot surface in approximately three to five hours. In an action that Asbjørn Søndergaard, chief technology officer of Odico Formwork Robotics, refers to as “detailing the whole formwork in one sweep,” the new technology is able to process that same surface area in 15 seconds. Strikingly, this timescale is applicable to both straightforward and advanced design formwork.The 19-ton Experiment B prototype, installed adjacent to Aarhus's Marselisborg Lystbådehavn in July 2018, is an extreme example of what can be achieved with this new method, displaying future possibilities of construction. According to Søndergaard, it is the hope of the consortium that the highly optimized concrete formwork is translatable and ultimately adopted for everyday projects such as minor infrastructural works and standard residential or commercial development.
Fjordenhus in Vejle, Denmark, is the first completed building by artist Olafur Eliasson and architect Sebastian Behmann. Together with Studio Olafur Eliasson, the duo have created a thoughtfully conceived and crafted structure in the bay of a Danish fjord. In their earlier architectural collaborations—like the curtain wall design for the Harpa Concert Hall in Reykjavik, Iceland—their work has displayed an attention to detail, composition, materials, and craftsmanship that carries over into this unique commission.
Once they convinced their client, Kirk Kapital, to build its headquarters in the water of an underutilized shipping port, they created a cylindrical concrete structure as a reference to the area’s surrounding grain silos.
The building is composed of four intersecting concrete volumes arrayed around an open public space and faced with nearly a million custom-designed bricks. The four-story volumes morph in elevation from ellipses to circles, and out of these are carved porous openings that dramatically frame views of the fjord. Built atop a man-made island with a basement foundation, Fjordenhus looks like a medieval rampart as imagined by Louis Kahn. But up close, its exterior walls are a pattern of endlessly and beautifully textured color.
The designers created 15 different hues of unglazed brick, added a smattering of blue, green, and silver glazed bricks, and then meticulously laid them out in digital drawings to create a patterned composition for the entire building. The brick colors were selected to reflect their immediate surroundings (more blue at the top of the building and gray for the stairwells), and they are meant to embody the changing weather and light conditions of the site. The torqued elliptical forms are intended to create a series of dynamic, flowing spaces that are “constantly calibrating to allow the user to trust themselves,” according to Eliasson, as they enter and pass through the building. The artist cited Erwin Panofsky’s criticism of neoclassicism and how it prescribes the inhabitation of buildings as an example of what not to do in designing architectural space. Eliasson wanted to move away from classical hierarchical planning to a more democratic, participatory architecture that he considers a hallmark of Danish democracy.
The building is entered from the quay by a footbridge that leads into a circular public space with three of the artist’s sculptures and a mirrored ceiling piece that reflects the light of the fjord back into the occupied public space.
A circular elevator that features dramatic top and bottom lighting, along with a surrounding stair that rises on splayed armatures, take users up into workspaces fitted with furnishings, lighting, built-in cabinets, and interior stairs all designed by the firm. The placement of furniture is purposefully haphazard so that users “democratically” negotiate their own paths through the space, giving them co-authorship of the building.
In addition, Eliasson designed table and floor lamps made of deep green glass and metal, as well as built-in lighting that is equal parts functional lighting and sculptural object. Lower floors have elegant, circular concrete pads with coffered lighting overhead. The top floor has a globular, faceted sculpture placed below a skylight that throws sunlight over the space. In addition, the rooms have a series of Eliasson-designed fixtures elegantly cobbled together from a hanging LED light fixture that casts light upward through a glass lens, creating a pattern of concentric circles on the ceiling.
This unique practice is based on an artistic sensibility devoted to materiality, craft, and an understanding of form, developed through Eliasson’s years of experimentation as a trained sculptor. As a result, it is a challenge to more traditional architecture practices. Furthermore, the designer’s insistence on the necessity of creating a democratic, user-controlled space means Fjordenhus comes as close to a contemporary Gesamtkunstwerk (or total work of art) as we have yet experienced in the 21st century.
