The ROI of BIM:
Why is it so difficult?

Decision makers often requests a calculation of the Return for their Investment. When it comes to BIM, the calculation of a single number (the strict definition of "ROI") is difficult and arguably limited in practical value. Decision makers are more interested in a wider understanding of what they (and their company) are getting back.

In this note I present my thoughts on the ROI measurement limitations and how to address investment decisions for BIM.
Introduction Return on Investment or ROI is a common evaluation metric to decide on investment projects. In certain contexts it is a back-of-envelope assessment of performance of an opportunity. It simply states the ratio between the expected returns and the required investment, and is often presented as a percentage value. (ROI = Return/Investment). The Return is the net impact of the implementation, meaning the difference between the value before and after the project is executed, or the gross return minus the investment.

When BIM is not the answer

Is Building Information Modelling the catalyst of improvement in all things Architecture, Engineering and Construction? Is "BIM" the Midas touch for all innovation projects?
This article explores the boundary conditions of BIM and suggests reasons for resisting its adoption. A new look to an old discussion.
Introduction I am a confessed BIM enthusiast. Early adopter or visionary, I embraced the technology as soon as I was exposed to it, approximately 10 years ago, and have been trying to convince anyone willing to listen about its benefits. Now, a decade into my struggle to make a better world through BIM, I would like to step back and ask myself if there are good reasons why other people have not jumped at BIM with the same conviction...
My logic is structured around the three letters of the acronym, hoping to identify the boundaries in these three dimensions.

My reading list
Mathematic explorations

Back on the saddle after a long silence, this time bringing a list of books that have kept me busy... is this a good excuse for not writing blog entries???

With a deadline for this afternoon I cannot spend a lot of time describing each book... yet I want to push myself to communicate some of the mind-opening good reads I came across recently. Most are not new books, and probably you will recognise them.

Without further introduction, here's a list of books about maths, with a twist:

Godel, Escher, Bach: and eternal golden braid by D. Hofstadter

The_Emperor's New Mind by Roger Penrose

In Pursuit of the Unknown: 17 Equations That Changed the World by Ian Stewart

Introducing Chaos, a graphic guide

Art and Physics by Leonard Shlain

Things to Make and Do in the Fourth Dimension by Matt Parker

So, these are some of my current and past reads. Have you read them? Any recommendations down these lines?


In future entries I will explore books about design and programming, creative code, artific…
