Adopting Changes in BIM - Parametric Modeling | Aedas | News & Events

By Sam Cho, Head of Parametric Modeling

We work in an ever changing world; the only constant thing is change.
 
To deal with the problem of constant change, architects have to create a work flow that foresees and anticipates the multiple changes a project will be go through over the design phase. Parametric Modeling is the answer to part of this problem. The term parametric means the use of selected criteria and variables which can be adjusted accordingly when changes occur. The criteria can be statutory like GFA and plot ratio or material criteria like compressive strength of concrete, chosen and designed to the construction of a parametric model.
 
Through alternation of variables within the parametric model, the computer can generate a range of new models based on the prescribed logic. Similar to mathematic equations, the parametric model is an accurate representation of the logic described and its possible relationships.
 
This approach is incredibly powerful in the sense it eliminates human error, preventing manual re-work, and creating a systematic and logical approach to complex design. Instead of creating form and design intrinsically, this approach demands the designer to understand the design from basic logic, and to back the design with a step by step scientifical approach. Personally I find parametric model extremely useful, particularly during the schematic stage design, it is to me a valuable tool and a fundamental change in the method of doing architecture.
 
Through Aedas R&D and HKPDA, I use parametric tools both in project and academic research. The invaluable overlap and flexibility allows me to integrate new technology into the daily workflow while investigate on potential research topics through workshops and studio sessions in universities.
 
With possible integration to Building Information Modeling (BIM) in the near future, parametric modeling is here to stay. It should be envisioned as part of the workflow, an integrated component and a vital process in the architectural industry.
