Professor Martin Fischer om BIM Alliance roll i BIM-utvecklingen
BIM Alliance var på plats under Veidekkes seminarium "Digitalisering och VDC inom Bygg och Anläggning" den 9 september. Vi passade på att prata med Martin Fischer, professor på Stanford University.
You are a part of the successful center CIFE at Stanford for Virtual Design and Construction. What is the most exciting thing happening in BIM development right now?
"I am really excited about the optimization potential. It is difficult and time consuming to come up with a design that is aesthetically pleasing and also has good cost performance, a good scuttle performance, a good CO2 footprint, and so on. Using computers we can change the design and calculate the performance of the design and learn so much more about the different drivers of a good design."
"With cloud computing we explored every possible option in 5 000 parallel computers in 8 hours in one project. We were able to look at every possible situation that could emerge over the life of this project."
What do you think of the development and implementation of BIM in Sweden from an international perspective?
"It seems that the development has been accelerating quite a bit compared to a few years ago. Before it was more limited examples and now we are starting to get project stories, more concrete examples and more data."
"Sweden isn’t any better or worse than others. The main difference internationally is the capability of subcontractors. You have some subcontractors here that are capable even by international comparison, but that is not yet the norm. In California for example we have many subcontractors who are capable of working with these tools, and competent in terms of collaboration as well as in terms of producing for tomorrow."
What are the most critical aspects in achieving a continued increase in BIM, both in regard to the number of users and the level of technical development?
"A clearer vision from the companies in project leadership and of what they want to achieve. That gives you a benchmark of which you can learn and get better. And a bit more of persistence, not so much from the younger people who are more comfortable with technology, but from senior project managers. They need to resolve difficulties that will arise and can’t just say 'well, I told you it wouldn’t work'. Instead they should think 'well, we can try one more time because we learned something and now we are smarter'. I would like to see more perseverance."
What role do you think organizations like BIM Alliance play in the development?
"I can think of three main roles. First, BIM Alliance has a role in sharing good practices. If you don’t share what is a good example the learning will be very slow. You have the visibility from all your members and many projects and say 'wow, this was really cool, let’s explain it', so that the learning can be faster."
"You can also help with the standardization. We need to have standard formats, but it’s also important to have a standard way of thinking about processes and a standard way of looking at metrics and measuring them. We have to know that we are talking about the same thing. You can see the whole picture of standardization."
"I think you can see new opportunities and new technologies. We’re not going to get stuck in this level of technology. You can get the broader vision of what’s going on."
