Collaborative Design and Engineering History, Current Practice and Possible Future
Léon van Berlo To create a data driven industry @berlotti Carpenter Architectural Engineer Researcher Netherlands organisation for applied Scientific Research TNO Mission to improve quality of life and competitiveness of industry Developing, implementing and disseminating technology Focus on openbim; avoiding any kind of lock-in for industry Open source BIM collective; BIMserver.org; BIM Bots; BIM Quickscan ; BIM Execution plan generator; National BIM Guidelines; geobim.org and many more.
BIM Collaboration
SHARED DATA MODEL shared data model
Common misconception: Shared data model is NOT equal to: Shared data(base) Shared BIM model instance Shared data model comes from the need to share/distribute data in a standardized way. let s agree this is a door shared data model == creating agreements (interoperability)
BIM data flow through standards: reducing interfaces
There is no CENTRAL model (in a multi discipline project)
Denmark 2006:
Found conclusion: Working (live) in a central BIM has more downsides than advantages. (ownership of objects, legal aspects, BIM manager, change requests, etc...)
Centralizing data stimulates wrong behaviour
So now what?
Split in the BIM market Practitioners Policy makers
Split in the BIM market Practitioners Policy makers BIM is not a goal, but a great way to achieve the goal BIM is the goal
Split in the BIM market Practitioners Policy makers BIM is not a goal, but a great way to achieve the goal BIM is the goal Bottom up What is needed to finish the work Top down What is needed to finish the story
Split in the BIM market Very high level of knowledge Work with what is available Write documents Get their inspiration from the UK Focus on working with BIM/data Focus on mandating working methods, tools and creating standards

Is the split a problem?
IFC
Lessons learned In a fragmented industry, with fast developing technology, we see a constantly growing ecosystem of data Mandating and dictating does not provide solutions, and always lacks behind practise
Just to be clear: Nothing wrong with an online system to help you do your work.
Current practise
The real questions are: What do I need to do my job? What do others need from me to do theirs?

Pontsteiger Prominent Amsterdam location 316 apartments (including most expensive penthouse in Amsterdam) 100 million construction costs Everything in BIM from the beginning Quotations and contracts based on IFC Rule checking Just in time logistics based on IFC Suppliers deliver data in IFC Cranes and support constructions in 4D BIM Fire safety analyses with IFC Simulations (wind, fire, energy) base on IFC And so much more

It works
It works but only when it comes from bottom up
