The AkzoNobel Leading in Specification panel discusses the use of BIM in the Construction Industry.
BIM was the second issue tackled as part of the Dulux Trade Leading in Specification construction debate.
Nigel McKay, Project Manager at Lend Lease: “We are using BIM at the moment and we’re using it on a project with regards to clash detection, as most probably would for a 3-D environment. We’re using it with regards to understanding the construction methodologies, linking it to the programs, especially around when we got CLT on board, rather than just building out of concrete. But eventually it’s going to be about how do you actually… how can you map the energy from the building a lot easier to actually think about how you would redesign it in the future. You’re seeing more organisations now going to things like activity-based working. You know, the worlds that Microsoft, and people like that, live in with regards to how they use buildings. That’s going to start to become the norm. Those technology organisations are going to be helping us actually inform as to what they want out of them because they’re much more flexible and agile.”
Nick Schumann, Director at Schumann Consult Ltd.: “My question about BIM, and I’ve never heard anyone answer this for me yet, is that I hear and read a lot about BIM being the thing that is going revolutionise and completely change the way we work as an industry and change all relationships and behaviours within it. I can’t see any evidence of that complete culture change. To me, a simplistic model in my head is when I see a construction contract between a client and major contractor like SKANSKA, and the contract is a BIM model. So everything to do with that building, at that point in time, when you’re committing a price, is in that model. Legal, commercial, technical, now, future… everything in that model that then gets picked up and taken, in a contractual legal environment, through to completion and then on to maintenance. Then it would have revolutionised everyone.
Nigel McKay: “From a BIM environment, I was doing my first 4-D CAD in 1995, so, you can definitely learn from that. What did it do? Immediately it took ten per cent of the materials out of the specification, going into a BIM environment, because you always procured ten per cent more because the designs were all on paper. Going in to a model, you didn’t have to design to that level of uncertainty, so waste was big. You could take ten per cent of the capital cost of material immediately out of the game. At my last oil and gas company, the margins were between the fifteens and the twenty per cent, not the two to threes, so therefore resource is very different; resource is much more abundant. BIM is a great example of the fact that, if you put the right resource to actually have the right accuracy of data going in the model, you can use the model for so much more. If you try to do BIM on the cheap in this market all you’re going to end up doing is absolutely creating some monumental problem somewhere, because rubbish in, rubbish out.”
