Abstract
A BIM (Building Information Modeling) model consists of multidisciplinary model elements. A model element includes numerous parametric attributes, such as quantitative geometric information and qualitative non-geometric information. Hence, information management is a significant issue for BIM technology, process, and applications.
There are two key features of information management with regard to BIM: lifecycle management of engineering information and integration of interdisciplinary information. Due to the long time span of a building lifecycle through different phases, from project planning, design, construction, to operation and maintenance, there is an abundance of complicated lifecycle information with regard to the model elements with different LODs (Level Of Development). In addition, different disciplines provide a variety of domain knowledge, and the productivity and efficiency increase through collaboration among domain experts. The semantic information is also diverse in accordance with the differences in domain knowledge.
In sum, a BIM model always needs to be modified or updated because of the frequent changes in a building project lifecycle. In other words, the parametric attributes within the model elements need to be modified or updated. The aforementioned process can be defined as information feedbacks because each modification or update is based on the correct data provided by stakeholders from different domains.
Concerning the needs for collaboration of BIM model modification, this research conducted a scenario analysis and proposed a scenario-oriented information management framework. Based on the framework, an interoperable object-based information feedback system was developed to improve the efficiency of the process. This system managed the feedback information by using a database approach. A corresponding management user interface was designed for a model manager to manipulate feedback information provided by stakeholders. A BIM model could also be automatically modified or updated at object-level of its model elements through the designed system instead of operating the model modification manually. In addition, this research designed a unique schema-free data structures and developed a web application for the information feedback end in order to enhance the interoperability among different BIM tools and fulfill the needs for cross-platform and asynchronous collaboration.
