I like a good challenge - so I decided to pick Uniclass 2 as the subject matter. It should be a joy of a topic to cover in 20 slides with 20 seconds a slide. A summary of the presentation is below:
What is wrong with existing Uniclass?
Ironically, it is not unified.
- There is no logic between many of the tables. For example Table G Elements and Table J Work Sections. An internal wall is G-252. Plasterboard within this wall is J-K10.
- Civil Engineering and Buildings have no relationship. So we have H-7321 Lighting for Civils and G-6431 for Buildings. This is a real problem for rail projects - these typically have buildings (station waiting rooms) as well as civils (rail, tunnels, bridges).
- All of these tables were designed for a paper way of working. The future is digital objects representing the real world. Not paper.
|Silos for buildings and civils - change is needed|
There are a number of new tables now under review. The new classification is logical and unified. There is also a single Work Results table that unites all of the tables. Some slides to demonstrate this below...
|Table CO - Complexes (eg. a recreation complex)|
|Table EN - Entities (eg. a building or a bridge or a tunnel)|
|Table AC - Activities (eg. dining or changing)|
|Table EE - Elements and Table SP - Spaces (breaking down your building further)|
|Table SS - Systems and Table PR - Products (eg. a washbasin assembly or a tap product)|
|Uniclass 2 - Perfect for COBie|
How can I find out more about Uniclass 2?
My blog post above is a bit of a "dummies guide". There are some far better resources on the web:
- Official CPIC consultation page:
- RIBA's Stuart Chalmers fantastic "search/visualise the data" tools:
- Detailed article by NBS John Gelder on Uniclass 2:
The tables are currently up for consultation. The first tables should be published in January.
