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

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. Boundary 1: Building Is Buildings  the only target of BIM?
