Construction management system has been needed to be anchored and revitalize in these days, since it was entered into a domestic market. We could consider application of CM services as a challenge of construction project system and a way to get to an advanced nation in construction field. Application of CM services could be possible in public projects by a regime. However, in case of private construction projects, it is hard to apply it without understanding of substantial necessity and propriety. so in this study, we find a application method of CM services to private small-midium construction projects, and make CM services item table of CM services for revitalization by examining the cases that applied to in private small-medium construction projects.

As contemporary society becomes information-oriented, major construction companies have recently invested in information management, but small and medium ones have not. Though the small and medium companies recognize the information management is necessary and important, they don't have an ability to possess technical expertises. The purpose of this study is to develop a Schedule Risk Control System based on blogs using IT and web technologies for construction managers in small and medium construction companies. The system makes a chance to identify risk factors and prepare for responses to settle risks happened in preconstruction phases, and enables the managers and headquarters to predict and handle schedule risks by sharing information about risks on the blogs.

Modern society is developing rapidly due to the convergence of industry and IT technology. In that case, the role of construction work that provides basic infrastructure can be very large. Recently, as construction work becomes more complicated, larger, and more advanced, the importance of management, such as system improvement for quality improvement, has become even more important. However, when a quality control problem occurs at a construction site, much time is required to solve the problem. In order for a construction project to be successful, various systems need to be organically connected and able to manage optimal decisions. In this paper, provide a quality control model using GCM push alarm service based on RESTful_API. The proposed model is a model that can be used by construction company quality control rooms and project managers for decision making. When applied to construction site project management, it is expected that more efficient and safe construction management will be possible.

Purpose: The purpose of this study is to prevent construction safety accidents, and the design safety systems were reviewed. This paper aims to establish as an effective system by looking at the implementation procedures and contents of the design safety review system. Method: We reviewed the purpose and content of the law, accident statistics, etc. for the study. In addition, we looked at the implementation plans for actual construction sites using the 'design safety' assessment process as defined by the Act. Results: We divided it into the data review phase, the risk factor elicitation and alternative setup phase, and the design safety assessment report preparation stage. Conclusion: it is necessary to derive risk factors that take into account the diversity of construction sites. However, the effectiveness of other reports is questioned as they are often copied and written. Therefore, it is necessary to strengthen external verification procedures attended by construction safety experts.

By nature, smart construction technology is a convergence technology, therefore aptly constructing and running an information system is needed in order to effectively develop and maintain it. Thus, in this study, an information system prototype was developed for the creation and linking of high precision digital maps at road construction sites for the effective performance of the development of the Information Collecting and Analyzing Techniques in the Construction Site (ICAT). For this, (1) defined input/output (I/O) data of each technical detail of ICAT, (2) analyzed the data flow, (3 ) proposed an information system prototype for high precision digital maps development and connection. Based on the information system prototype constructed in this study, it was inferred that each technique and its information for the Smart Construction Technique Development Business was in a consistent flow. Developed information system prototype would enable effective cooperation between subjects directly involved in the technique development, by defining I/O data in advance. Moreover, it would be of value to practitioners for refining the output data from each technique, thereby linking databases and forming Entity Relationship Diagram.

Recently, the restriction of contracting business between general and specialty contractors are deregulated, which means the elimination of the traditional market entry block in the Korean construction industry. It could be a threat and/or an opportunity to construction firms, and requires establishing new business strategies in order to obtain relative competitiveness between the general and the specialty. Under this change in the industry, this research performed to provide some suggestions for specialty firms in setting up their new business strategies by analyzing various changes of their competitiveness elements. This study extracted 20 core competitiveness elements from major 6 competitive categories required in doing specialty contracting business, and their relative importance between the 20 elements were measured. It was found that the specialty's relative competitiveness has been greatly changed and affected by the deregulation of the protective business restriction.

The aim of this study is to compare relative efficiency Korean and Japanese construction firms over the period of 2000-2013, and to analysis relative efficiency using Data Envelopment Analysis (DEA). This study employs DEA in analyzing of 7 Korean construction firms and 8 Japanese construction firms using 2 input and 1 output variables. The efficiency results of this study is temporarily lowered due to IT Bubble Decay and Global Financial Crisis. The efficiency of Korean construction firms from 2000-2001 is lower Japanese construction firms, but the efficiency of Korean construction firms from 2002-2013 is higher Japanese construction firms. These results mean that the management of Korean construction firms were operating more efficiently than Japanese construction firms.

The goal of enterprises is to make a profit. They should change and evolve themselves according to various customers' demand and developing information technology. The construction industry has not been used to such a change of business environment, although it has a long history. So it needs a new management system that accepts the various demands of construction participants and keeps pace with the evolving environment where is replaced by high-valued one. In this point, this research's objective is to apply SCM which shows visible outcome in the manufacturing industry, to the construction industry. This study regards the concept of SCM not as a simple management method, but as a comprehensive one. In other words, SCM is composed of three viewpoints; control, organization and information technology. SCM is to improve process by new management method, to benefit each other by strategical cooperation among participants, and to make information delivery and saving system for maintaining the relationship.
