For example; concrete columns and slabs couldn't be considered as managed assets, could they?<br /><br />Anonymoushttps://www.blogger.com/profile/11546610460741193310noreply@blogger.comtag:blogger.com,1999:blog-5634085675780254011.post-71426113610195340792014-05-24T04:45:25.030+10:002014-05-24T04:45:25.030+10:00Its also very important to mention that the COBie ...Its also very important to mention that the COBie tool from Autodesk that is available to the public for free is NOT the one that was used in that Challenge... Not even close. The free one doesnt even do 10 percent of the one they used in the "challenge." Ive heard *rumors* that the real tool from the challenge might be available to the public one day soon, but so far they are all just rumors.Aaron Mallerhttps://www.blogger.com/profile/08146075275463175361noreply@blogger.comtag:blogger.com,1999:blog-5634085675780254011.post-67371731594950198212014-05-23T23:47:07.343+10:002014-05-23T23:47:07.343+10:00Hello,

In this year's COBie Challenge ArchiCAD performed 100% with zero errors (you can see the result in the table towards the end of the following web page):<br />http://www.nibs.org/?page=bsa_chall14_gs<br /><br />Also, ArchiCAD is now certified for both IFC Import and Export:<br />http://www.buildingsmart.org/certification/currently-certified-software-products<br /><br />For anyone who wonders about last year's results, the following page gave and explanation:<br /><br />"Well, although the official press-releases don’t mention it, the initial pilot project that the vendors were require to model was particularly difficult. Apparently, given this was a mock project, many of the parameters were left blank by some participants, and actually marked for completion by the “end-user” as would be the case in a real-world scenario.<br /><br />These were then interpreted by the buildingSMART judges as errors, and penalties applied. According to a source, all submissions made this type of error, however in the case of the Graphisoft submission, this error was replicated many times throughout the project file – thus accounting for the large penalty difference."<br /><br />Source: http://revitall.wordpress.com/2013/04/09/autodesk-wins-buildingsmart-cobie-challenge/<br /><br />Laszlo Nagy<br />ArchiCAD-Talk Moderator, Site Admin<br />http://archicad-talk.graphisoft.com/profile.php?mode=viewprofile&u=13Laszlo Nagyhttps://www.blogger.com/profile/12802088500889443470noreply@blogger.comtag:blogger.com,1999:blog-5634085675780254011.post-65303732300483591152013-12-31T10:58:35.138+11:002013-12-31T10:58:35.138+11:00Tom, l suspected the same, but without spending a ...Tom, l suspected the same, but without spending a lot of time working through the inards of COBie it is hard to understand what the significances are of the differences. Sure Bentley did more attributes, but are they all required?<br /><br />l decided to use the results anyway because I assumed the point of the challenge was to compare the different softwares. Maybe I was mistaken.

H...Congratulations. Very good article/white paper!<br /><br />However on the results of the COBie challenge the stats you quote aren't the whole story. As I like to say, there are no statistics that aren't darned statistics. For example Revit my have scored 9 minutes compared to Bentley's 218 minutes. However Revit only exported 8748 attributes compared to Bentley's 18117 attributes. That was the downfall for Bentley on the overall score. "183 entries were missing the unit field. A penalty of 183 minutes (1 min/row) was applied for this error."<br /><br />I'm thinking that Bentley produced twice as many records. That's twice as many that I don't need to create. But that's not how the score was derived, so while Bentley likely did a better job, they were poor at taking the test. What my comparison here does indicate is some of the differences between how the two scored and that's the real story. Look at the results chart on the detailed sheets for the products and you can get a better idea of how each did. In my mind there was no clear winner.<br /><br />For easy reference http://www.nibs.org/?page=bsa_chall13_autodesk and http://www.nibs.org/?page=bsa_chall13_bentley<br />Tom MacKnighthttps://www.blogger.com/profile/05941604903991869046noreply@blogger.comtag:blogger.com,1999:blog-5634085675780254011.post-69536948619007340502013-08-30T11:54:12.403+10:002013-08-30T11:54:12.403+10:00Excellent article.

This is a great resource for those that have not had the "pleasure" to go through this on a project before, and will be of great help with framing the discussion with an owner to understand what data they want and how it will be used.Dave Baldacchinohttps://www.blogger.com/profile/00431940617680243953noreply@blogger.comtag:blogger.com,1999:blog-5634085675780254011.post-58954222556434357512013-08-04T23:07:46.981+10:002013-08-04T23:07:46.981+10:00Good article Antony...!

Even some of the self proclaimed "Experts" on this issue, who have helped in the deliverable to a project tend to not see there information used months past delivery. Makes you think. When most facility organization see their budgets cut first they generally can't afford a long term engagement with a consultant to be on staff. This means, we as an industry to make this work have to find a better way, or run the risk of its relevance. My fear is this gets couple together with great process, kind of like death by association.<br /><br />Keep up the good work my friend!Anonymoushttps://www.blogger.com/profile/06455563762154136852noreply@blogger.com
