Identifiyng a Subset of BPMN for IDM Development

Abstract: The purpose of this paper is to propose a subset of business process modeling notation (BPMN) to improve the information delivery manual (IDM) development process. The information delivery manual (IDM) (ISO/DIS 29481-1, 2008) currently recommends using BPMN for describing process maps (PM). The BPMN model is a generic graphical representation standard for specifying business processes targeted at a wide range of industry sectors. In its present form, it includes an unwieldy number of symbols and rules (currently over 160 notations) in order to cover a wide range of uses. Consequently, many process models use only a small number of these notations. This study collected and analyzed BPMN notations used in 54 processes in 14 existing PMs developed by various organizations. It was found that only 36 notations are used in IDM development. Based on these 36 notations, a subset of BPMN for IDM development is proposed.

FRAMEWORK OF THE EXTENDED PROCESS TO PRODUCT MODELING (XPPM) FOR EFFICIENT IDM DEVELOPMENT

Abstract: This paper introduces a new “extended Process to Product Modeling (xPPM)” for efficient Information Delivery Manual (IDM) development. The current IDM development typically uses Business Process Modeling Notation (BPMN) to represent a Process Map (PM). However, the resultant Process Map is isolated from the development of Exchange Requirements (ERs) and Functional Parts (FPs). ERs and FPs specify the information required when information is exchanged between different activities. The extended Process to Product Modeling (xPPM) method is proposed to provide a tight connection between PMs, ERs, and FPs. The theoretical framework is based on the Georgia Tech Process to Product Modeling. An xPPM tool is being developed in Java to support several IDM development efforts in South Korea.

The architecture development for the interoperability between BIM and GIS

Abstract: The purpose of this study is to propose a scalable architecture that can be supported via the BIM (Building Information Modeling) on a GIS (Geographic Information System) platform for information interoperability between various heterogeneous systems such as BIM, GIS, and FM (Facility Management). This platform requires the acquisition of information from various data sources such as IFC (Industry Foundation Classes) and DBMS (Database Management System) if a use case for facility management, energy management, and design evaluation needs to be implemented, followed by a transformation of the information into appropriate information that can represent the perspective suitable for the use case. IFC may be considered a method for information interoperability, but it has a limitation in representing information in the perspectives of the use cases. Unlike the support of information interoperability based on the existing IFC, we would like to approach the problem of GIS- and BIM-based information interoperability by separating the problem in terms of geometry and property information. The geometry information is transformed into a simplified surface model from the IFC geometry information for that visualization of a number of objects represented in the GIS. The information required for the use case perspective is extracted and transformed from the property information by utilizing ETL (Extraction, Transform, and Load). ETL is a technology that extracts, transforms, and loads information from a variety of data sources and has been used for OLAP (Online Analytical Processing) function implementation via data mining in the management engineering arena to represent perspective-oriented information. In this study, we have applied ETL from the perspective of BIM. For this purpose, we have reviewed the related study trends and derived a general use case of BIM on a GIS platform. Further, component architecture is designed to implement the use case as well as a Star Schema to represent information according to the perspective for the development of a data warehouse. On the basis of these, BGP architecture is proposed for implementing the ETL concept using BIM on a GIS platform. Furthermore, a use case for the facility management of Korea Institute of Construction Technology is implemented as a prototype to show the usefulness of the proposed architecture. Thus, in this study, we demonstrate that information required from the perspective of project stakeholders can be interoperated effectively.

Smart Space with a Built-in Ubiquitous Sensor Network (USN)-based Online Monitoring System at Sungkyunkwan University in Korea

Abstract: Recently, advances in smart sensors and information technology have made building structures more intelligent. In particular, the ubiquitous sensor network (USN) system, which consists of a range of smart sensors and a wireless communication network, is being employed widely as an essential tool to provide a safe and clean environment with a range of applications including automation, fire prevention and security. This paper presents, a smart space test-bed with a built-in USN-based online monitoring system established at Sungkyunkwan University in Korea for both functions of structural health monitoring and environmental monitoring. For the structural health monitoring function, accelerometers, strain gauges, tilt-meters were installed at the host structure and the vibration mode shape, deflection and displacement of a specific member of the host structure were monitored in real-time. Temperature sensors, humidity sensors, CO2 (Carbon dioxide) sensors, windy direction/speed sensors, CCTVs (Closed-Circuit Television) and motion sensors were installed at the appropriate locations for environmental monitoring inside and/or outside the host structure. In addition, all the information obtained from the deployed sensors was collected as a database and an integrated web server which can be connected very easily through the mobile apparatus of the various platforms such as a tablet PC (Personal Computer), a smart phone, MID (Mobile Internet Device), and etc. was constructed. Finally, the built in USN-based online monitoring was integrated with BIM (Building Information Modeling) maintenance for future guidance in ubiquitous environments.

An object-based building product model: from modeling to documentation

Abstract: In Korea, construction industries have started to recognize the importance of the conceptual model of building objects to integrate various information from different views on a project. An object-oriented model was proposed and implemented partially. The implemented system of the model at this stage aims at the automatic generation of two dimensional drawings from three dimensional objects even though the objects defined in the system carry more information than just geometric properties. Information regarding structural analysis, construction planning, and scheduling is represented in the model. It was concluded that three separate modules need to be developed to cover the most popular structural types of current projects : reinforced concrete, steel, and shear wall. However, these modules share many objects which represent architectural components like non-bearing walls, openings, stairs, rooms, doors and windows. To be a flexible design tool, an input mechanism for a model should facilitate a three dimensional CAD system. Once objects are defined and placed through a user interface in a CAD environment, the system creates objects which in turn are checked for consistency. There are access functions to retrieve data for other application programs.

Why Some BIM Tool Users Do Not Think of Themselves as BIM Users - A Preliminary Study

Abstract: Some people claim that they are not users of building information modeling (BIM) even when they use BIM tools. This study investigates why some non-BIM users believe that they are not BIM users by analyzing their perceptions of BIM. To this end, a survey was conducted with BIM and non-BIM users in the Republic of Korea. The survey consisted of questions about the perception of BIM and non-BIM users toward BIM use, process, organization and policy. The results show that suspicious non-BIM users account for 65% of non-BIM users. The analysis of the survey reveals that non-BIM users who actually use BIM tools have a higher expectation of the level of overall BIM adoption than BIM users have. They believe that they are not BIM users, because they currently deploy only basic BIM uses that do not require a high level of collaboration, and they do not have a BIM specialist (BIM manager) in their group. Further research on the global view of BIM users is recommended.
