The BIM Task Group
by Nick Nisbet, Director, AEC3 UK. Advisor to UK Government BIM Task Group
The BIM Task Group is charged with providing the information needed by industry to help meet the Government's purposes in receiving data, along with supporting the Governments pilot projects.
During the first half of 2012 the BIM Task Group delivered a suite of documents to support the adoption of COBie. Many of the questions and uncertainties being expressed have already been addressed directly by the COBie Data Drops and the COBie UK 2012 downloads. Between them, they illustrate and define the level of development expected and the use of classification. The requirements for classification are also embedded in the examples and blank templates as automatic drop-down lists.
The expected properties for Types are in the COBie templates.
The COBie-UK-2012 document does provide guidance on Naming of asset objects but strictly to the extent required by the COBie conventions: in summary, uniqueness and no 'special' punctuation. There is no need for any other restrictions as the role taken by naming conventions in the past are fulfilled by Category and other Attributes and associations. The recent publication of BS 8541 part 1, 3 and 4 has also provided guidance on the delivery of template Type objects, library Type objects and manufacturer Products.
There are already a couple of formal 'MVD's which define the maximum information content of COBie drops up to Tender and up to Handover. The UK documentation already contains extensive text and illustrations of the client Purposes and the content of the Drops. We are now working on developing these and the templates already published, into tables of object Types, groups of Attributes and the expected delivery based on the new CIC stage-gates. These schedules will then represent the minimum requirement for each Drop.
