Abstract

A construction project requires collaboration of a large number of individuals working in different organizations to deliver the project on time and within the budget. Architecture, engineering, and construction industry spends time and money to solve the information sharing and interoperability issues between different domains. With the advent of building information modeling, a 3D CAD model of a project is used as a shared knowledge resource during the design, construction, and facility management phases of a project’s life cycle. Currently, 4D models are created by combining CAD and schedule information. A 4D model is useful for detecting potential construction conflicts during the project planning and design and a valuable tool during construction. However, creating 4D models requires a great amount of human involvement. An approach that facilitates integrating BIM and schedule information can improve efficiency and is highly desirable. This paper presents a new approach to information modeling using the Semantic Web technology. The Semantic Web provides an infrastructure and a data modeling format that allows computers to access and combine information distributed over the Internet. The paper discusses: (1) ontologies that the authors have developed for BIM and project schedule information; (2) how ontologies are used for creating project knowledge bases in RDF/OWL format; and (3) how project knowledge bases can facilitate machine processing of project information and semantic interoperability among project knowledge bases. The Semantic Web approach allows information to be saved once at the provider source and be used by authorized users as needed. This means BIM information is created and maintained by designers and project schedule is created and maintained by schedulers on their respective servers. This would allow the latest BIM and project schedule information to be accessed over the Internet and combined for various purposes.
