Structural change

Most of us are well acquainted with the benefits of CAD/CAM/PLM technology when used in manufacturing.

We have also seen US architect Frank Gehry use CATIA V5 3D solid modelling to design complex prestige structures such as the Bilbao Guggenheim, and by others in the restoration of the Sagrada Famila in Barcelona. So why isn’t the 3D revolution embraced by more of the architectural fraternity?

There are many reasons. Some architects cite the general availability of ’adequate’ 2D tools, while others complain that before you can carry out effective ’what if’ design in solids you have to model a complete scheme. And while the architectural world has been on the brink of 3D solids for a while, an alternative 3D revolution has been taking place in the shape of BIM (Building Information Modelling) that is somewhat analogous to PLM in manufacturing.

Put simply, BIM provides a consistent database for the whole structure, including integrated/collaborative data for all disciplines involved: architecture, structural engineering, MEP (mechanical, electrical and plumbing) engineering and contracting. Everyone in the design and execution chain would access the system in much the same way as the various collaborators in an automotive/ aerospace project would access the PDM systems of the main players.
