BB MAKE – A COLLABORATIVE AND OPEN STRUCTURE by IAAC Beijing Design Week 2014 This year Barcelona had the honor of being the guest city for the Beijing Design Week 2014, implementing the “Barcelona, a future inspired by design” exhibition in the 79-Tank, an impressive circular precinct in district 751. The Barcelona City Exhibition, designed by ExitDesign, won the prize for Best Exhibition of BJDW2014. In this framework, the Institut Ramon Llull, content curators of the exhibition, invited architecture and design schools of Barcelona to develop a proposal for the realization of an installation, finally selecting the Institute for Advanced Architecture of Catalonia’s (IAAC) BB Make proposal, presented by Areti Markopoulou and Mathilde Marengo.   BB MAKE – BARCELONA BEIJING MAKE The BB Make proposal, developed by IAAC, in collaboration with the China Central Academy of Fine Arts, explored the potentials of new technologies applied to design, through the generation of a participative collaborative structure, enhancing local materials with advanced technologies. The structure consisted in bamboo beams, a well known local construction material, held together with digitally fabricated joints, in particular 3D printed joints and CNC milled joints, fabricated onsite, allowing the joints to be easily customized, so as to deal with the irregularity of the natural bamboo material, and finally allowing the structure to grow easily. OPEN AND PARTICIPATIVE DESIGN The design phase of the joints was developed through a workshop, run onsite by IAAC digital fabrication and computation faculty Alexandre Dubor and Rodrigo Aguirre, during the week prior to the Design Week. The Workshop was held at the Chinese Academy of Fine Arts with 15 local students, giving the local students the opportunity to be introduced to digital fabrication techniques, as well as new software necessary for this implementation. Through the application of 3D printing and CNC milling a series of joints designed were elaborated. These designs were then combined and integrated to finally develop one single base joint typology. A press fit joint was developed, allowing easy customization and allowing to overcome the great irregularity in the bamboo beams, differing in size from 40mm to 60mm. For the final structure, 22 different joints were fabricated through the customization of the original design.   COLLABORATIVE MAKING During the Design Week, the BB Make structure was constructed thanks to the participation and collaboration of the local visitors, and the CAFA students. The structure was composed of a primary structure, implemented with bamboo beams, and held together with the 22 customized joints fabricated onsite in the 79 Tank. On top of this, in the interest of allowing the local visitors to further personalize the structure, hence fully taking advantage of the perks of digital fabrication, and finally making the structure “theirs”, a secondary structure was implemented using split bamboo beams, where the visitors could CNC mill a personal message, and connect this to the primary structure through simplified joints. The BB Make installation finally represented the physical implementation of an exchange of knowledge, as well as culture, thanks to the combination of local materials and participation, with technologically advanced fabrication techniques, one of the fields of investigation developed in IAAC. Towards facilitating the access of these digital fabrication techniques during the Design Week, IAAC generated a “popup” Fab Lab inside the 79 Tank, among which the user could access and use 3D printers and a CNC milling machine. The collaborative implementation of the structure allowed people, from students and professionals of the fields of architecture and design, to the general public, to have the opportunity to be introduced to new digital fabrication techniques, with the support of trained professional, as well as having the opportunity of actually realizing their designs through these techniques, and finally constructing the BB Make structure throughout the duration of the BJDW2014.
