An industrial robot in situ fabricator fabricates a 3D grid structure filled with a type of concrete that has specific flow characteristics in the planning phase all parameters such as insu lation performance heating output and ventilation data as well as the subsequent room temperature and energy costs at varying times of the day and during different seasons are calculated in advance As a result the digital BIM facility model becomes a real time based control monitoring and measuring center that technically and economically optimizes a building s entire lifecycle Here s a case in point in this context even before construction starts ar chitects can rotate and move the digital twin around the site and simulate various locations in fast for ward mode across the four seasons in order to iden tify the building s energetically optimal orientation and design among other criteria All new opportunities The latest digital applications are the subject of intensive study at ETH Zurich as well Matthias Kohler Professor of Architecture and Digital Fabri cation says Digitalization is bringing a new build ing culture For the architect it is a paradigm shift At ETH Zurich which provides important impetus in this area researchers from eight departments are working together with industry experts and plan ning professionals They explore and test how dig ital fabrication can change the work of designing and building The objectives pursued in this con text are flexibility in design sparing use of mate rials time and cost efficiencies and enhanced quality control An S shaped wall featuring so called mesh mold technology pictured left is an example of such digital fabrication The new con struction technology combines the functions of re inforcement and shaping in a steel mesh fabricated by robots enabling the cost efficient and sustain able production of reinforced concrete structures of any desired shape without the need for complex casings A functionally integrated floor featuring an unusually complex shape was placed atop this dig itally fabricated wall The slab formwork was pro duced by 3D printing In this case all the data of the structure were provided by a BIM model as well Sorting the data maze To prevent users from getting lost in the data spac es of a BIM model with many terabytes the total information and complex pictures are split into layers in which the relevant data for the respec tive construction teams are stored Structural Digitalization is bringing a new building culture For the architect it is a paradigm shift Matthias Kohler Professor of Architecture and Digital Fabrication ETH Zürich 80
