Experts and non-experts are expressing their opinions on the subject in magazines and blogs, and we have also heard what designers of long career or young age have to say.
It is inevitable that – when you “have” to conceive each project with a BIM logic – only those who have adapted will survive (as happened thirty years ago for those who had to abandon the pen for CAD).
What the “elderly” fear is the depersonalisation of the design idea, facilitated by the need to immediately entrust every detail of the construction – aesthetic, functional, performance and economic – to the machines.
But it will not be like that, except for those who willingly do without the effort to invent.
If the process of engineering and, then, management will be facilitated by the computer modeling system, “behind methods such as BIM will always remain the thinking heads of designers, who – before relying on any tool – will continue to follow a linear design path(*)” based on their experience, culture and sensitivity of each, on knowledge of the initial framework of information within which it will develop.
The time for the BIM is not yet ripe: even major international works still partially give up Modeling “to streamline procedures” (so Kieren Porter, BIM Manager of Patel Taylor on the website of the Chartered Institute of Building (http://www.ciob.org/).
