The Architecture, engineering & construction (AEC) industry domains have grown more complex and larger. BIM is a digital representation of a building to facilitate the exchange and development of construction information integration and interoperability. Industry Foundation Classes (IFCs), under development by International Alliance for Interoperability (IAI), represent the part of buildings or elements of a process. IFC has been adopted as a central information repository in order to deliver integrated information. BIM softwares could open the IFC file, recognize standard objects. However, sometimes, information distortion or information loss occurs during information exchange. As project participants exchange BIM information by using BIM softwares they will need a reliable and efficient exchange of information. This paper suggests the BIM object information compatibility problems among BIM softwares and classify the BIM object information compatibility problems.

Green building information used by the AEC industry is diverse and extensive), causing difficulties for personnel regarding the collection and utilization of information in the form of inaccurate searches about related laws, inefficient management of searched information and overlapping works. Therefore, this research aims to propose a law search system utilizing metadata for more accurate and efficient searches of green building information. The proposed system is expected to contribute to improve productivity of construction projects by reinforcing the accuracy and efficiency of searches for the collection and utilization of green building information.

최근 건축물이 대형화되고 비정형화됨에 따라 기존의 2차원 도면으로 3차원을 표현하는 데 한계가 있고 설계오류파악, 공사 물량과 공사비 오차의 발생, 시공오류의 예측 부재, 기둥, 보, 기계설비 배관 등의 부재간의 충돌 등의 문제점을 개선하고자 건설 현장에서 BIM(Building Information Modeling; 이하 BIM)이 사용되고 있다. 그러나 실질적으로 건설 공사 현장의 직원들을 대상으로 BIM의 사용법을 교육하고 평가하여 실질적인 구현 방법을 충분히 숙지하게 한 이후에 BIM을 공사 현장의 공사 관리 업무에서 사용하게 하여 BIM 사용에 따른 효과를 분석한 연구는 전무하다. 이에 본 연구는 BIM의 교육, 평가, 실시에 따른 공사현장에서 BIM의 효과를 설문조사를 통하여 실증적으로 분석하고 개선방향을 제시하고자 한다.

건축공사 규모의 대형화 복잡화, 다양화가 되면서 다수의 현장에서 공사수행에 따른 많은 공사정보가 현장에서 발생하여 본사로 보고되고 있다. 이러한 많은 정보들 중에서 개별현장 및 다수의 현장을 동시에 관리하기 위해 중요한 핵심정보만을 추출하여 경영진이 현장을 지원하기 위한 적절한 의사결정을 내린 수 있도록 하기 위한 필요성이 증가하고 있다. 또한 건설산업의 정보화가 추진됨에 따라 현장에서 발생한 정보를 효율적으로 취합하여 의사결정을 내리고 공사관리를 행하는 것이 기업의 경쟁력을 확보하는 요소로써 그 중요성이 증가하고 있다. 따라서 중소건설업체에서 다수의 현장을 동시에 관리하기 위해 본사차원에서 요구되는 기본적인 정보요소와 핵심적인 정보요소를 규정하고 그에 대한 활용방안을 제안하였다.

Systems architecture of information models for construction industry is introduced. The architecture ful fills international standards, such as ISO 10303(STEP) and IAI IFC, etc. It is defined in web service description language(WSDL) and ISO 10303-11(EXPRESS) language. A standard platform for this standard architecture is also developed. This platform has several tools which can transform EXPRESS description file into C++ or Java languages and which also can generate an IDL file or OWL file from an EXPRESS file. System architects, software engineers, information system consultants can use these standards to define their information model for construction industry in standardized way. Construction engineers can test this information model with ease using standard testing tools and testing method, which is also a part of standard architecture of information systems for virtual construction.

Workforce information is important in production planning because production planning requires matching a production unit's capacity to loads of assignments. However, tracking and managing workforce information such as skills and accident history is not an easy job. This paper describes a prototype database system for a workforce database system that employs RFID technology. This system tracks daily workforce production capacity on sites. A pilot project is described to explore the benefits and possibility of using radio-frequency identification (RFID) to track and manage workforce information, and is followed by the results of a survey to identify benefits. In addition to the survey identifying the benefits of the database system, the paper also presents a list of challenges through a series of interviews.

Many construction projects have used the building information modeling (BIM) extensively considering data interoperability throughout the projects' lifecycles. However, the current approach, which is to collect the data required to support facility maintenance system (FMS) has a significant shortcoming in that there are various individual pieces of information to represent the performance of the facility and the condition of each of the elements of the facility. Since a heterogeneous external database could be used to manage a construction project, all of the conditions related to the building cannot be included in an integrated BIM-based building model for data exchange. In this paper, we proposed an ontology-based facility maintenance information model to integrate multiple, related pieces of information on the construction project using industry foundation classesbased (IFC-based) BIM data. The proposed process will enable the engineers who are responsible for facility management to use a BIM-based model directly in the FMS-based work process without having to do additional data input. The proposed process can help ensure that the management of FMS information is more accurate and reliable.

As urbanization increases in UAE, the demand for housing and infrastructures also grows. The challenge is to continue to build but in a different way considering more energy-efficient sustainable buildings. Producing a sustainable design is highly dependent upon effective participation among the diverse parties involved. In the construction industry in the UAE, these parties are fragmented due to the multistage nature of construction projects and multidisciplinary participants, particularly during the design stage. The decisions made during this stage have an extensive impact on subsequent stages of a project's life cycle. Having a sustainability expert during the design stage is important and the awareness of sustainability requirements by all design participants is of equal importance. In this research, recent advances in information technology are used to develop an information model that will improve the sustainability of building during the design stage. An information framework for storing design information and sustainability performance criteria is developed, allowing design participants to collaborate in an integrated environment. This research is expected to help designers produce sustainable designs for building projects.

In the construction industry, construction management system using information technology has been applied diversely to increase productivity. Although IT device such as PDA, RFID, Barcode, wireless network and web camera has been introduced in construction site, the usage of these device is restricted, because these cause engineer to do additional work. The suggested process using Digital Pen in this study, which can lessen engineer's additional work, get defect data promptly. Also accumulated data is utilized effectively for analyzing construction site. The purpose of this study is to introduce Digital Pen System as a means of construction data acquisition for improving productivity.
