    A 6-Step Systematic Process for Model-Based Facility Data Delivery
    Thabet, Walid; Lucas, Jason D. (2017)
    The use of BIM for FM by owners is growing, yet there are challenges that exist because of the need for customized data standards to fit each owner's need. This research examines the development of a model-based approach for capturing and handing over facility data. Previously completed research consists of a spread-sheet based documentation method for capturing identified facility-related information to support an owner's operation and maintenance of educational facilities. An approach was developed and piloted to validate a process that utilized milestone information submissions for documenting appropriate information throughout the design and construction of a facility using a spreadsheet based approach with direct input into the Computerized Maintenance Management System (CMMS). Using a pilot project approach, this paper builds on the spreadsheet based approach by identifying how the facility information could be captured throughout the project using a model based approach. A six-step systematic process is defined for BIM-FM integration to capture facility data and integrate the information into a CMMS. Various challenges and considerations to capture and deliver facility data are discussed. The paper also discusses the need for further validation of the proposed process and summarises ongoing study to test the proposed approaches using a second pilot project.

    A BIM-based Object-oriented Data Model to Support Sustainable Demolition Waste Management Decision Making at End-of-Life
    Hamidi, Behzad (Virginia Tech, 2015-05-22)
    Sustainable demolition waste management is rarely practiced within the construction industry. This is mainly due to the fact that the decision-making process for sustainable demolition waste management is a very resource-demanding and time-consuming task in terms of data collection and data management. The decision-making process includes multiple analyses of possible demolition waste management alternatives from economic, environmental, and social perspectives. Such analyses require waste managers to capture and manage huge amounts of data scattered within fragmented data sources at the end-of-life of a building. The process of capturing and managing this information for the building end-of-life would be time-consuming and costly. Therefore, the waste managers are reluctant to pursue sustainable demolition waste management practices in order to prevent potential delays and incurred costs. This research identified information that is required to conduct sustainable demolition waste management analyses. The identified information was then classified based on information sources. An object-oriented data model (OODM) was proposed to allow the waste managers to more efficiently store and manage the information at the end-of-life phase. Furthermore, a sustainable demolition waste management prototype application was developed to demonstrate how the required information is captured from different sources of data, stored within OODM classes, and retrieved from the integrated database. Finally, the proposed OODM was verified in terms of its scope, flexibility, and implementability. The goal of the research is to offer a method for storing and managing end-of-life information in an efficient and effective manner to support sustainable demolition waste management decision making. To achieve the goal, this dissertation outlines the objectives of the research, the methodologies used in developing the object-oriented data model, conclusions, limitations, and potential future research work.

    Implementation and Evaluation of a VR Task-Based Training Tool for Conveyor Belt Safety Training
    Lucas, Jason D.; Thabet, Walid (2008)
    Conveyor belts are dangerous to the working environment and the source of many injuries and fatalities that end up costing the industry a lot of money. In order to reduce the injuries that occur on an annual basis, better training techniques are examined. Virtual reality is examined as a way to enhance current training practices that consist mainly of slide show presentations and videos. Virtual reality is examined for task-based training where the user can interact with a working environment safely. The user is given tasks to complete within the virtual environment similar to tasks a worker would have to complete on a day to day basis. The purpose of the program is to be a method of rapidly training younger miners while supplementing on-the-job training practices and ultimately reduce accidents. The model was developed using CAD software and then imported into Deep Creator's Right Hemisphere where animations were added and functions were programmed to objects. The user's performance is tracked through the use of LISP programming and scores are tallied to judge user performance. The application was tested for quality of information, usability, and learning potential over other training methods.

    A Pilot Model for a Proof of Concept Healthcare Facility Information Management Prototype
    Lucas, Jason D.; Bulbul, Tanyel; Thabet, Walid (2013)
    Within the healthcare industry it is important that facility information is efficiently and effectively managed to aid in the successful operation and maintenance of the facility and provide a safe and well-maintained environment of care for patients and staff. In order to do this, a healthcare facility information management prototype was proposed. The goal of the prototype is to allow facility managers to more efficiently and effectively respond to facility related events within the healthcare environment. The prototype was designed by using case analysis methods to identify information needs and draw connections between clinical information and facility management operations. This information was organized into a product model which is used as an ontology to capture, store, and retrieve the information. A conceptual model is developed to demonstrate the potential use of the developed product model in aiding facility managers' responses to facility related events. The conceptual model uses developed Graphical User Interfaces (GUI) that are mapped to the product model to demonstrate the information interactions. Information from one of the analyzed case studies is used as an example to describe the conceptual model development. A walk-through of the model is included to demonstrate how the different GUIs would be used to respond to the example event. This paper discusses the system architecture, the goals of the conceptual model and prototype, and the conceptual model development and validation. Future research strategies for the proposed healthcare facility information management framework are also addressed.

    A VR-Based Training Program for Conveyor Belt Safety
    Lucas, Jason D.; Thabet, Walid; Worlikar, Poonam (2008)
    The mining industry is characterized by the need for high volume of production which has forced its adoption of large and fast moving equipment for transporting bulk material. Belt conveyors have attained a dominant position in transferring material due to such inherent advantages as their economy of operation, reliability, versatility, and practically unlimited range of capabilities. With all of these factors comes an inherent danger. From 1995 to 2007 there have been a total of 534 equipment related fatal accidents in the United States as recorded by the Mine Safety and Health Administration, 50 of which are conveyor belt related. Most accidents around belt conveyors are caused by human error, improper maintenance procedures, lack of effective training or lack of awareness of possible hazards. To counteract this high number of accidents, virtual reality (VR) is being looked at as an alternative to current safety training programs. The structure and program being proposed consists of 4 steps in creating a two phased program. This paper discusses the step by step structure of creating a safety training program for belt conveyors and the first phase of implantation of the program. The first phase includes an instructional-based phase that allows for the presentation of the information compiled for the areas of training that were determined within the structure of the program. This paper will discuss the framework used in developing the VR safety training application, the first phase of the prototype development, how the data has been retrieved and organized, and how industry feedback was gathered and used to develop the application.
