Recently, BIM (Building Information Modeling) technique is being considered as a critical delivery condition for the public projects according to the increase of best practices by practical application of BIM. However, since existing BIM studies are focused on the design and construction phases, those results are not considering the life cycle of a construction project. Therefore, this study suggests an integrated BIM operation process that enables an application of BIM for each phase of a construction project from planning to maintenance phases and develops an integrated BIM system based on the suggested methodologies. This study developed basic BIM functions and its application process by analyzing information systems in each project phase for a bridge construction project. Besides, this study performed case study and survey analysis for construction managers to verify a practical applicability of the developed system. Therefore, it is expected that the integrated BIM system is going to be utilized as a 3D-based integrated information management system considering life cycle of construction projects.

The purpose of this study was to present the 6 sigma technique in construction projects, and to review the possibility of 6 sigma introduction. DMAIC (Design, Measure, Analyze, Improve, Control) methodology was used to increase the utilization of TIMS (Technology Information Management System). The results of this study were as follows. The introduction of the 6 sigma technique was very effective in the construction industry, but there were many difficulties in its application because of the characteristics of construction. As the 6 sigma technique emphasizes management based on data, it is essential to accumulate historical data and to achieve the standardization of the construction business process. Furthermore, it is necessary to apply 6 sigma for the competitiveness of the construction industry, and the development of suitable 6 sigma methodology for the construction industry is required.

While temporary construction work applies to a temporary facility, it has a high use frequency during the construction period accounting for around 10% of the construction cost, it requires systematic management. However, construction inspection information of temporary construction work often has no special specification in the design documents and specification items, with the items on various standards also being formidable. Because of this, related inspection are likely to be performed inefficiently with a high probability for occurrence of human errors when quality inspection is conducted for the temporary construction work. In the present study, therefore, apply to the electronic operation support system capable of supporting implementation of inspection of providing related information for the contemporary construction work. To achieve this, a prototype is developed by using IDEF0 to identify information flow by process and organizing EPSS-based quality inspection Task. And then, efficiency of the quality inspection and information accessibility for temporary construction work are to be improved by verification method of Sample Project.

The adoption of smart construction technology in the construction industry is progressing rapidly. By utilizing smart construction technologies such as BIM (Building Information Modeling), drones, artificial intelligence, big data, and Internet of Things technology, it has the effect of lowering the accident rate at the construction site and shortening the construction period. In order to introduce a digital twin platform for construction site management, real-time construction site management is possible in real time by constructing the same virtual space. The digital twin virtual space construction method collects and processes data from the entire construction cycle and visualizes it using a 3D model file. In this paper, we introduce a modeling automation technique that constructs an efficient digital twin space by automatically generating 3D modeling that composes a digital twin space based on 3D spatial data.

This paper aims to propose a method for the systematic management of construction information using ontology. In particular, it was intended to propose a method to systematically manage the construction method information required by designers and constructors. The information used in this paper is a case of test-bed construction resulting from 10 years of modernized Hanok technology development research. The new construction methods of modernized Hanok were organized using the ontology editor, Protege. To this end, the concept of ontology and the process of constructing ontology have been summarized through a review of existing research first. A conceptual diagram for constructing a domain ontology of the modernized Hanok construction methods was then proposed, and the effectiveness of the proposed domain ontology was verified using the SPARQL Query function of Protege. Finally, the defined classes and construction method metadata were published on the web using ontology web language (OWL).

Modern construction projects have stakeholders from various construction fields, highlighting the importance of efficient information sharing and collaboration. The expanding scope of Building Information Modeling (BIM), particularly in the domestic construction sector, necessitates a Common Data Environment (CDE). However, applying foreign commercial CDE solutions within the domestic context is challenging due to the difficulty of aligning them with the unique organizational structures and characteristics prevalent in the country. Furthermore, the information review and approval processes specified by ISO 19650 often fail to harmonize adequately with the domestic design procedures, limiting the full utilization of CDE advantages. This study endeavors to develop a Korean CDE collaborative platform based on ISO 19650, with a focus on adapting workflows and information container systems to the domestic context. Building upon the requirements of ISO 19650-based CDE workflows and information containers, this research involves an in-depth analysis of information generation, sharing, review, and approval processes within domestic design organizations, offering tailored CDE workflows and information container systems that align with the specific needs of the Korean construction industry.

Building Information Modelling (BIM) and Discrete Event Simulation (DES) are tools widely used in the context of the construction industry. While BIM is used to represent the physical and functional characteristics of a facility, DES models are used to represent its construction process. Integrating both is beneficial to those interested in the field of construction management since it has many potential applications. Game engines provide a human navigable 3D virtual environment in which the integrated BIM and DES models can be visualised and interacted with. This paper reports the experience obtained while developing a simulator prototype which integrates a BIM and a DES model of a single construction activity within a commercial game engine. The simulator prototype allows the user to visualise how the duration of the construction activity is affected by different input parameters interactively. It provides an environment to conduct DES studies using the user's own BIM models. This approach could increase the use of DES technologies in the context of construction management and engineering outside the research community. The presented work is the first step towards the development of a serious game for construction management education and was carried out to determine the suitable IT tools for its development.
