The Evil Digital Twin

The term ‘Digital Twin’ has recently become popular in BIM & Digital Engineering circles. However, to have any value, the digital twin needs to contain relevant, easily accessible information. All the data generated during design and construction is not necessarily useful. This post examines both good and bad digital twins.

Digital Value Pyramid

Technology is certainly part of the solution, but should not determine strategy alone. In other words, ‘because you can’ is not good enough- there  has to be a specific and measurable benefit.
In this post, I illustrate this concept using a ‘digital value pyramid’

BIM: The new typing pool ?

In the olden days, many organisations had a group of people (nearly always women) in what was known as a ‘typing pool’. The idea was that if you needed a non-handwritten document, then these people would apply specialist skills (typing) on an incredibly complicated bit of kit (a typewriter) to produce said document.
A surprising number of organisations still work in ‘typing pool ‘ mode when it comes to BIM.

BIM: But I’ve got 3D goggles

A construction project, with quality documentation so everything fits together properly, budget and program are achieved (or improved upon), construction runs efficiently and there are not any acrimonious legal disputes at the end between client, designers, contractor and subcontractors is an elusive beast.
3D goggles aren’t going to make much difference.


With BIM, it is easy to get bogged down in technology & detail and neglect the important strategic aspects. In this post, I draw parallels between the approach needed to successfully get down a mountain on a bicycle, and that needed for BIM.
