ABSTRACT
This article focuses on how to specify relevant information content in objects and object libraries in order to exchange relevant and reliable information in building information model (BIM)-based software. There is a general lack of professional information in BIM-based designs. The AECOO (architects, engineers, contractors, owners and operators) industry should therefore take the initiative to achieve a broad consensus about the specification of relevant information that should be standardized as content in the objects. Improved exchange of information in BIM-based software will support integrated design and delivery solutions. Objects/object libraries are proposed as the container for the exchange of information. Software objects (doors, windows, walls) and object libraries (selections of objects) with specified professional information (measurements, performance, energy, fire resistance, noise reduction, etc.) are called ‘BIM objects’. The ‘role- and life-cycle information model’ (RIM/LIM) concept is suggested as a framework for development (specification) of relevant information in different roles and phases of a building's life cycle. A ‘BIM object information standard’ can be based on the RIM/LIM framework. Content in the BIM objects can be included as specifications in information delivery manuals and BIM guides.
