Does nD BIM exists?

How many dimensions we can consider for BIM. I recently read this article, which says we cannot have more than 4D for BIM.

Koutamanis, A., 2020, Dimensionality in BIM: Why BIM cannot have more than four dimensions?, Automation in Construction 114 (2020) 103153, https://doi.org/10.1016/j.autcon.2020.103153

Welcome to the forum @Sara

It’s a great question - I believe dimensions were originally developed for vulgarisation purposes (haven’t read the article yet…). That being said, we have identified 8 dimensional space : https://en.wikipedia.org/wiki/Eight-dimensional_space :slight_smile:

In the end it’s a question of creating common understanding. Thanks for the share!

Dear Sara
I just did an article for my PhD about this topic. Just to get things right: Never ever use just these dimensions! :wink: We had several projects where project managers just ordered these dimensions, which turned out to be quite costly.

Dear Adrian,
Thanks for your insight, and sharing your research experience. Nice paper!
I totally agree with you and Erik, that BIM has more dimensions. I was thinking of inviting the authors of this paper, to discuss this study further in detail !?!
Best,
Sara

Hi Sara,
In my perspective, having worked with 3D BIM and 4D schedules, 5D estimation and controlling, now working with data for FM in relation to models, there are way too many use cases to use the simplified dimensions.
The nD can be good for buzz, getting engaged with clients and starting a dialogue about why to do it and what to define as a goal, but not as a standalone definition.

Totally agree, Andreas, this is - I apologize - nowadays more or less BS buzzword bingo.
