“Parametric BIM design is a tool that brings benefits when it comes to addressing today’s architectural challenges”
Phase 2 of the development of the computational parametric design of the complete spatial structure of the stadium roof
Today, parametric BIM design is a tool that brings clear benefits when it comes to addressing today's architectural challenges. This technology consists of applying algorithms to the parameters that define the design of buildings. This way, professionals can develop increasingly complex designs and/or evaluate a large number of design variations in a briefer period of time compared to traditional design techniques.
TECNALIA has completed the second phase of the project to replicate the roof structure of the Grünwalder stadium using parametric BIM design: passive design was used by the architect Jonathan Chanca, a lecturer at the Elizalde Academy in Donostia.
In the first phase, the parametrisation of a straight section of the structure (spatial nodes and wooden bars) was carried out by means of a script in Autodesk Dynamo in which customised nodes had to be created using Python.
Second phase of the project
In this second phase, more scripts have been generated in Autodesk Dynamo: we have also developed new custom scripts using Python, contemplating curved sections and corners (joints between straight and/or curved sections). All of this has enabled the entire structure to be modelled in Autodesk Revit.
These algorithms need some input parameters (inner roof line, beam type...) that are defined by the user before running it. To obtain different structure designs, it is only necessary to vary these input parameters and re-run the algorithms.
TECNALIA's range of advanced digital construction services
TECNALIA offers a wide variety of advanced services in digital construction to facilitate the work of professionals, such as computational design, to facilitate design processes and the generation of complex geometries, the generation of customised tools (add-ins and plug-ins) in the predominant BIM design software (Autodesk Revit, Rhino, Autodesk Navisworks, etc.), and the integration of data from different sources in 3D interfaces to optimise the management of asset information.
In short, TECNALIA's range of advanced services allows actors involved in the construction process to improve their participation in the design, construction, operation and maintenance phases of BIM projects through technology and digitalisation.
