Techology Transfer
“TETRA projects translate scientific knowledge or explore the application domain of
new technologies or methods. They provide concrete information that fits in the
everyday practice of Flemish enterprises (SMEs and social profit organisations). The
projects are aimed at increasing their innovation potential to ensure that they can
develop new products, services or processes faster.
These, in turn, offer potential to improve the economic performance of the company.”

Building Information Management
“[Management is] the control and making of decisions in a business or
similar organization [and] the process of dealing with or controlling
people or things”
Hornby, A.S. , Crowther, J., et al (1995). Oxford Advanced Learner’s Dictionary
of Current English (5th edition). Oxford University Press

1. Does using BIM guarantee less data-loss in a building process? Or, in
other words: does BIM has the intrinsic quality of eliminating data-drops,
when used with adequate interoperability?
2. Does building data grow (infinitely) over time in any typical building
process and is the amount of “knowledge” (data) bigger in later phases
than in early ones?

Editor's Notes

  1. I would like to share with you some views on BIM, that are important for our on-going applied research.
  2. Together with our research partners from PXL-tech…
  3. And a LOT of user group members we have recently acquired funds for a TETRA-project.
  4. TETRA stands for Technology-Transfer, and in our case the technology to be transferred is LEAN. Well spread in production-industry but less-known in building industry, especially not in the Belgian Building Industry…
  5. In short our research will transfer some of the twenty-something LEAN-techniques into building practice. We will be targetting multiple disciplines in the Small and Medium sized Enterprises and – of course, our I wouldn’t mention it here – we will be using BIM to do this…
  6. It needs little explanation that we will be focussing on Management rather than Models or Modelling…
  7. But what is Management? My dictionary defines it mainly as some sort of ‘control’ over a process or in the case of BIM: data...
  8. And often “managing” our data is stimulated by a fear of loosing it. I am well aware that many (if not all) of you know this diagram, and some of you probably hate it, but is interesting to study it for a little, as it brings up to important questions…
  9. Does BIM equal no or at least less data-drops? Does a Building Information Model needs to “grow” over time?
  10. Let’s have a closer look into managing the data within our models
  11. Is the green line representative for the actual data in our models? Or is the red one a more realistic diagram? I think everyone present – as a BIM-user – must have had this thought: I’m sharing this model, but do I want to share all the data inside it? Do I actually know what data is stored in the various elements of the typical library I have been using. No problem for early adaptors and experienced users or for the larger companies…
  12. But a lot of SME’s will unfortunately will recognize themselves in the male in this picture…
  13. How can LEAN help avoiding this kind of problem?
  14. I was actually inspired/triggered by last year’s presentation, by Leon van Berlo, telling us that there is no central model – not anymore
  15. I believe there is no constant growth in “data” in general for a “BIM” over time. And I’m sure that the amount of data needed differs very much according to the party adding or extracting the information… As Pieter showed us (?) it probably is even better to store more and more data outside the model and keep only what is really necessary for interoperability – thus making our model LEAN…
  16. To illustrate all this (and to please my students present) I’ll end with a short example of what we will be testing and researching…
  17. These are the typical steps of a modular concrete-panel project at Enjoy Concrete. They receive a design in Sketchup by the architect. They have to remodel to make it usable and add the necessary data for identifaction and more. A rebar-model is made before production can start. Special attention is given to the position of hoisting fixtures, needed for mounting everything but no longer visible in the finished project.
  18. From a LEAN point of view, the second step should be eliminated. From a BIM point of view: data needed in the late part of the process should be present from the start, for a more efficient work-flow.
  19. This can be solved by using IFC-data in Sketchup (for instance with info about hoisting fixtures) and re-using this within All-plan. How? That is for our student Seppe to find out in the next few months…
  20. The outcome is a LEAN workflow, with and thanks to BIM-integration and data-management
  21. Any Questions: Seppe sits right over there.
