In response to the need of using electronic design data directly in construction management applications, many CAD developers have started implementing semantic data models in their CAD products using industry foundation classes (IFCs). While helpful, these semantic CAD applications have limitations when used in actual construction practices. The case(More)
This paper reports on experience inducting subcontractor process ontologies as part of research on the SEEK: Scalable Extraction of Enterprise Knowledge project at the University of Florida. We briefly review approaches to ontology generation and the application of those approaches to product/process ontologies in the AEC arena as well as process-oriented(More)
The transition to Building Information Modeling (BIM) represents a substantial shift from existing business practices in the architecture, engineering, construction, and facility operations (AECO) arena. While the move from drafting to computer aided design (CAD) sought to automate an existing business practice, successful BIM virtually builds a structure(More)
Continuing growth of energy use by commercial buildings has created a need to develop innovative techniques to reduce and optimize building energy use. Recently Building Energy Management Systems (BEMS) have gained popularity because of increasing interest in building energy conservation and savings. In this study, a conceptual framework for real-time(More)
In this paper, the authors discussed in detail about the framework of integrating Radio Frequency Identification (RFID) with Building Information Modeling (BIM) technologies. The proposed framework can be used in the computer-aided design, manufacturing, engineering, and installation processes. In specific, this paper explained how to use RFID technology(More)
The vision of semantic interoperability, the fluid sharing of digitalized knowledge, has led much research on ontology/schema mapping/aligning. Although this line of research is fundamental and has brought valuable contributions to this endeavor, it does not represent a solution to the challenge, semantic heterogeneity, since the performance of proposed(More)
