Feature BIM briefing


for Manufacture and Assembly] you got every subcontractor and manufacturer putting lots of details into your model, every possible detail about widgets you didn’t need to know. So what are the top metrics for BIM? DP It goes back to the intelligent client, who should be briefing for BIM. They should be articulating what outcomes they want to achieve from it, and then leaving the how to and detail up to the supply chain to allow people to innovate. We still have to stipulate, but there is still flexibility. MC The difficulty is that Aran’s business you could say is in the vanguard, while people like ourselves are still coming to the races. It’s people like us who need a bit more skeletal shape to help us. Once you’ve been there, you’ve probably got a picture. But when you’re just about to jump in... AV So if you’re jumping in, what do you have to measure? What KPIs do you need as a business? Where it’s a government contract and you’re expecting to get the asset back, what are you expecting in terms of data? DP Contractually we want three things. COBie UK 2012, that’s the data set, the format we want it in, the common language. Then we want the models because we want Level 2 BIM. That’s where we’ve got to define, in plain English, what Level 2 BIM is. And we want the 2D PDFs of the drawings as well.


3. The scoring system AV Picking up Martin’s point about contractors that aren’t fit and ready, [what will you do] when it comes to a scoring matrix to decide between getting a project and not getting a project? A bidder might be lowest cost but they’ve got no BIM facilities, or they’ve got great facilities but they’re quite costly, how will you balance that? DP We’ve got a series of working groups, and one of those is looking at legal and commercial issues, including looking at PQQ sets. But once you go beyond that stage, when you tender for the project, you can either supply that [BIM capability] or you can’t — it will be very black and white. MC So do you see it as being a PQQ differentiator, rather than at the final tender? DP It will be part of the PQQ set, but then once you’re into the tender stage it will be binary — you can either do it or you can’t. AV But as we take public sector projects more “online”, we detach the human interface. We’ve already said that in the industry, people don’t talk to one another. Now we bid through these portals — we don’t bid through people any more. I’m not saying it’s a challenge for you particularly, but it’s a general challenge for the industry. DP People interface with technology, but they integrate with other people. I use the analogy


that BIM is a 21st century camp fire — it brings people together. Technology is good but it should be able to bring people together.

4. Finding a wider audience MC What about housebuilders? Building a house is the smallest project , but it’s got the greatest repetition. DP That’s one of the biggest prizes. We had a briefing session last week, and some of the architects were starting to engage [with BIM] on the housing side. In terms of government role, any contract that is procured by central government will be part of the mandate, which takes in the HCA. MC The government has a fantastic opportunity through things like Building Regulations to influence the adoption of BIM. AV But we’re still playing catch-up, we’re still waiting for the BIM structures through things like PAS1192, we still have to align that with the RIBA design stages, and that doesn’t happen until about 2013. DP You’re right, but the Construction Industry Council has been working really hard with the [professional] institutions to give us our BIM overlay — where the data drops should be in terms of plans of work. We’re hoping round about April we’ll have the BIM overlay which should start to give alignment. It’s fair to say the plans of work have been built traditionally for the designer, this will be the first time the industry has a plan of work that’s written for design and construct, back-to-back with the client’s business case requirements.

5. Integrated project insurance AV One area where government is needed is to influence the insurance market. Before you can work properly in that [integrated] environment, we need a PI policy we can work to. Right now you can’t even buy it. DP Yes, some of the challenges around Level 3 BIM aren’t to do with the technology, it’s as much to do with project insurance. The legal and commercial working group is having that conversation with insurers. MC This is where government could be incredibly brave, because it could actually self-insure. On government projects, the government is picking the bill up, which includes premiums, which also raise the question of cost of entry. But if the
