Arup executed the archetypal design for the Marina Bayfront Pedestrian Bridge in Singapore by modeling the curved geometry to use less steel. Now picture the undulating form of a 23,000square-meter roof clad in transparent and translucent polycarbonate. HOK Sport ﬁnetuned the complex structure for Dublin’s I that were virtually unthinkable before,” said Buddy Cleveland, senior vice president, Bentley Applied Research Group. “They have upgraded from using computers to simply speed the drawing process to employing immense computational power to discover their ideal design.” Generative design enables architects and engineers to describe design components and relationships using elegant, Generative design enables architects and engineers to describe design components and relationships using elegant, powerful algorithms. Landsdowne Road Stadium using a parametric model to minimize the components. Now envision a walk through a light-infused educational center shaped like a Damask rose. Henning Larsen Architects optimized the petal-shaped design of the Massar Children’s Discovery Centre in Damascus, Syria, so it could be built by local contractors. Visionary architecture around the world has became a reality thanks to advances in smart geometry—made possible by a computing process alternatively known as parametric modeling, computational design, or generative design. The process allows architects and engineers to use rule-based design parameters and geometric relationships to create complex building components, then automatically apply changes in the parameters throughout the models to test the constructability of their designs. “In generative design, architects and engineers are achieving results and designs powerful algorithms. As the design progresses, a change to one component in the system automatically drives changes to other related components. Using this approach on even the most complex structures, designers can quickly explore a broad range of alternatives, speed their design iterations, and generate designs that are freer in form, more efﬁcient, and more ﬁt for purpose. Bentley’s GenerativeComponents uniquely preserves and exploits the critical relationships between design intent and geometry. Users can, for instance, dynamically model and manipulate geometry, apply rules and capture relationships among geometric features, and deﬁne complex forms through concisely expressed algorithms. When used as an extension of MicroStation, GenerativeComponents produces generative designs that can ﬂow through to detailed production and fabrication without information loss. GenerativeComponents software arose from a research project led by a Bentley director of research whose work attracted expert input from a network of elite early adopters. As the software solidiﬁed, the research transitioned to commercial product development led by Bentley Software. The Bentley developers continued to collaborate with the network of early adopters, who coalesced into the independent SmartGeometry Group. Bentley released GenerativeComponents as trial program for generative design in architecture and engineering in November 2007. Since then, the SmartGeometry Group has remained dedicated to educating the construction professions in the new skills required to effectively use advanced design systems such as GenerativeComponents. The directors of the SmartGeometry Group include Lars Hesselgren of Kohn Pederson Fox (KPF), Hugh Whitehead of Foster + Partners, and J. Parrish of Arup Sport. KPF’s Bishopsgate Tower, also known as “The Pinnacle,” was the ﬁrst major building to be approved for construction with a form completely designed and developed using GenerativeComponents. Construction of the 60-story building commenced in 2008 and, upon completion in 2010, The Pinnacle will become the tallest building in London. “KPF has been using GenerativeComponents for some time, forming a key component in the armory of the KPF Computational Geometry Group,” Hesselgren said. “Several of our most advanced projects employ GenerativeComponents as a tool for exploring thousands of options as well as the complex geometry to be used in ﬁnal construction, all ultimately beneﬁting our clients.” 18 Be Magazine | Volume 6 Issue 1 http://www.smartgeometry.org/ http://www.bentley.com/en-US/Products/GenerativeComponents/
