Original Abstract

The 2011UKGovernment BIM strategy is motivating lead design and construction organizations in the UK to use BIM authoring tools to help prepare information for progressive handover. Acquiring structured handover information is driven by specific purposes (use-cases), management criteria and inputs which are being documented using ISO 29481 (buildingSMART IDM) and ISO 12911 (Framework for BIM Guidance). Previous work has shown that IFC exports can be transformed into the required COBie format. These transformations can assume compliance to international standards or they can include tolerance of non-standard implementations. These decisions can be driven by market pressure pending the possible adoption of more consistent implementations. However there remain systematic gaps and weaknesses in the information sets being generated. These gaps may work against the efficient delivery of acceptable datasets by requiring tedious and potentially inaccurate manual attention. Examples of data issues include inaccuracy in the identification of envelope elements, and failures to distinguish functional systems and zones. The paper examines strategies for applying rule based transformations to highlight and resolve data issues, as a prerequisite to automatically categorizing the facility objects according to local classification systems. Rule strategies include direct authoring, systematic tabulation, and the RASE (requirements, applicability, selection and exceptions) approach. The strengths and weakness of these approaches will be compared and examples deployed to show how BIM models showing relatively weak completeness and accuracy can still generate valuable deliverables for the client.
