Up until now, the process of obtaining spatial information for facilities management (FM) has been very laborious and tedious, even with the use of computer-aided facility management tools. The proposed research utilizes BIM based workflow to capture object attributes such that the building data created in a BIM model may be brought seamlessly into Facilities Management system rather than recreated. The proposed system not only imports geometry of walls, doors, windows, columns, and so on, but also retrieves attribute data associated with these objects. Therefore, queries can be executed to obtain -needed information, generate graphical or data-based reports, and identify interesting trends in facilities operations and maintenance for appropriate management. Since the proposed approach is objectbased, the system will automatically calculate or display the area of each space, and add additional information about each space such as occupant information, capacity, type, equipment and so on. Open BIM standards are used to retrieve or store information in a BIM model as that will facilitate the exchange of information between different FM systems. A prototype of the proposed system was developed in collaboration with the University of North Carolina at Charlotte (UNCC) FM department. The prototype was tested for its applicability and flexibility for the UNCC FM operations and maintenance management. INTRODUCTIONEven though computer technology has progressed significantly over the past decade, the process of obtaining spatial information for facilities management (FM) continues to be very laborious and tedious. The general practice of collecting and storing data from a constructed facility is through the handover process, where the
This study proposes a 3D visualization model in highway design/construction that electronically represents information of highway projects. The 3D model will be based on the STEP (Standard for the Exchange of Product model data), which is an open standard, so it can be used as data structures. Since the design model includes integrated resources to represent 3D geometric shape and project management information of the infrastructure, the built visualization model will allow end-users to extract the necessary data from the object based 3D intelligent model. This integrated data model is expected to provide practical engineering information to improve the design/construction process. This study presents the framework for the integration of application programs such as existing 3D/CAD programs used in practice by applying the STEP-based information model and information technologies. With the system integration framework composed of the information model, data repository, application program, and application programming interface, this research proposes establishing a prototype system according to the system integration framework so that end-users can manage information of an infrastructure in an integrated computing environment. The final output of this research is to present a methodology to automatically generate a construction schedule from infrastructure facility design information. This method is performed by the full connection between construction quantity takeoff analysis and design information by using the information model.
This paper examines the System Engineering processes/applications transforming from being document‐centric to being model‐centric by examining the benefits and uses of the Systems Modeling Language (SysML). This paper will look at the concept behind SysML and provide a background on existing research to address the Unified Modeling Language (UML) Systems Engineering request for proposal to generate SysML. This paper will identify benefits of using SysML in the Systems Engineering process and makes a recommendation for its use in large scale integration projects and complex hardware and software designs.
