TECTONIC AGGREGATIONS FOR DESIGN FOR MANUFACTURING AND ASSEMBLY
A GLOBAL CRISIS, A NOVEL SOLUTION According to the World Economic Forum, about 90% of cities around the world do not provide affordable housing of adequate quality to their citizens. Do emerging fabrication technologies offer a solution to this global crisis? Research for “Tectonic Aggregation” began by looking into housing solutions proposed by some of the 20th centuries most visionary architects. Architects whose proposals were described by many as “utopian,” perhaps a polite word for unrealistic. Perhaps today’s emerging fabrication techniques, discreet design methods, and efficient modes of production may facilitate novel housing solutions that were once regarded as impossible.

KISHO KUROKAWA TAKARA PAVILION The Takara Pavilion was designed by Kisho Kurokawa for the 1970 World’s Fair in Osaka, Japan. At this time, Kurokawa focused the majority of his work on Japan’s “invisible” traditions, including the impermanence of structures in the country due to destruction by weather and war. The four-floor framework of the upper structure is composed of prefabricated steel-pipe modules. It forms a tree structure stretching out in all directions. The structure has the metabolist potential to extend, or replicate horizontally and vertically depending on necessity.

BENEFITS OF DFMA Design for Manufacturing and Assembly is an approach to construction that emphasizes offsite-construction whenever possible. According to Autodesk’s Az Jasat, the approach has gained popularity in recent years in response to the global skills shortage. DFMA is accomplished through: Optimizing how parts will be put together in the field Maximizing the repetition of parts used and optimizing connection methods Prioritizing the usage of ‘ready-made’ parts
BENEFITS OF CLT CONSTRUCTION CLT construction remains the most logical material for projects utilizing a DFMA approach for several reasons: Because panels are prefabricated, erection time is greatly reduced, which improves efficiency and results in lower capital costs and faster occupancy. CLT panels are manufactured for specific enduse applications, which results in little to no job site waste. It is relatively easy to increase the thickness of a CLT panel to allow for longer spans requiring fewer interior support elements.
