This presentation will focus on innovative tools and processes used to transfer from design to fabrication for cladding support steel for the King Abdulaziz Centre for World Culture, due to open shortly.
Inoclad as a specialist facade consultant supported Seele (Main Facade Sub-Contractor) with the design and documentation of bespoke elements to permit a unique, landmark tower facade form like no other to date. A combination of Grasshopper, Python and Manual modelling in Rhino produced fabrication model detail in the .3dm file format. But this does not explicitly support steel fabrication processes including ordering, cutting and assembling on an tower project scale. Given that each steel element was unique in shape, size and orientation, “tracing” the model in fabrication suitable software would have likely resulted in program delays and been subject to human error in creating and reviewing the resulting model elements.
Geometry Gym supported Nurol Gulf with Grasshopper scripts and plugins to reverse engineer the .3dm files (primarily polysurfaces with meta data) into Tekla which is very proficient for digital fabrication.
When a second fabricator was engaged to accelerate fabrication program, Geometry Gym supported Inoclad to generate the fabrication model in the openBIM IFC format from Grasshopper, which could then be directly imported into Tekla, both processes using Geometry Gym plugins.
Jon Mirtschin, Director Geometry Gym Pty Ltd
Jon Mirtschin is a structural engineer with a computer science degree, and has been supporting Engineers, Architects, Builders and other AEC Professionals with tools and processes to permit model interchangeability and design transfer. An emphasis on OpenBIM exchange using advanced use of IFC has been central to these workflows.
As a structural engineer, Jon worked in London for Expedition Engineering on projects including Infinity Bridge, 2012 Olympic Game Velodrome and Torre Intesa Sanpaolo. Previously at Connell Wagner (now Aurecon) in Australia, projects included Wembley Stadium, Melbourne Cricket Ground Northern Stand redevelopment and Eureka tower.
He formed Geometry Gym in 2009 to focus on Software development and project support. The software tools primarily exist in the form of plugins for Rhino, Grasshopper, Revit, Tekla, Navisworks and a multitude of structural analysis applications.
