In construction of high speed railway, the fan shape is limited to achieve reduction of required travel time and concrete railway which has structural stability and induces small maintenance cost with allowable ground settlement is recently applied. So construction of concrete railway on soft ground in which considerable ground settlement occurs increases and settlement management in soft ground section is required. Field monitoring on ground movement and integrated geotechnical information system which manages construction, design, and field monitoring data are essential for settlement management of concrete railway subgrade. Site investigation data are also required due to future repair work. Therefore in this study, integrated geotechnical information system for construction and maintenance of concrete railway is developed. The developed system consists of a database and an application program. The database contains site investigation, construction, design, and field monitoring data throughout a railway. Application program performs various functions on managing and utilizing information in the database with graphic visualization of output. And by providing integrating information with comprehensible visual displays, the applicability and effectiveness of the developed system for construction and maintenance management were confirmed.

Researches of current PMIS(Project Management Information System) information searching focus on providing personalized results as well as matching needed queries in an enormous amount of information. This paper aim at discovering hidden knowledge to provide personalized and inferred search results based on the ontology with categorized concepts and relations among construction data. The current PMIS searching occasionally presents too much redundant information or offers no matching results from large volumes of data. In this paper, we propose a service searching system, which becomes aware of users device using iPMIS(Intelligent Program Management Information System). And we design and plant the ontology-based iPMIS, which is aware of the context in its environment.

This paper presents a fundamental study to establish a standardization system of the Construction Continuous Acquisition and Life-cycle Support(CALS). States of standardization in the Construction CALS were reviewed to find some defects in developing CALS system in construction industry. It is analyzed that three of major parts were needed to put up a standardization system for the Construction CALS. Firstly, the range of Construction CALS standardization is set up by identifying of Construction CALS and defining the standard and standardization. Secondly, the strategy to enable more effective implementation of Construction CALS standardization and the relationship of the concerned system presented can be used for establishing the Construction CALS standardization system. In addition, the spread and application device is proposed for using Construction CALS standards at public institutions and construction related companies. Conclusively, a classification system of the Construction CALS standards was proposed and some objects to be standardized were presented in the classification system. What were studied in this paper will provide the primary information and guidance to develop a guideline for standardization of the Construction CALS.

The production process of construction industry is different from thing of the general manufacturing, likewise various participants make temporary teamwork for success of the project through sharing of information. But the each role of participants is individually changed to step in construction process stage and moreover it has complicated, entangled interests. The Construction Management was inducted for the effective management and operation of construction project. The Key of the Construction Management success depends on the cooperative relationship relation to major participants. The domestic construction system is difficult with many trial and errors for the frequent plan change. As the building are more bigger and complicated, Building Information Modeling is demanded design and maintenance. This evaluation was done by the trust on the system as well as Construction Management. And then it applies the BIM it analyzes the example of construcrion project.

The major objective of construction process control(CPC) is to provide construction managers with operational information that will help reduce project duration and save project cost. However, the CPC in Korea is being applied to construction projects with some basic problems such as the inconvenience of CPC S/Ws and the process control unconcerned with construction information classification system and computer system to integrate cost and schedule. This study analyzes the present condition of CPC including the basic problems, and then suggests the reform measures in technical and operational viewpoints to reduce construction risk. The focus of study is on the technical improvement for the application of construction information management system applicable to both cost estimating and schedule management.

Although various IT-based services including PMIS are used at construction field, there have been limits on communications, such as fast reaction, information loss, and information security in the real world. Therefore, this paper proposes to adapt a social network service (SNS) that has already been used for information management and sharing information at the company level in other industries in order to support construction information management and communication in a fast and accurate manner. Following the requirement analysis through literature review and site interviews, the paper presents an SNS-based construction information communication and sharing system named PMIS+. PMIS+ was tested and validated for its feasibility at construction sites and it was proved that the proposed system and information management framework using the system could be helpful for effective information management at construction fields.

Our government suggested an integrated construction information classification system (CICS) for improving construction information exchange between project participants. However, because a database for integrating construction documents and drawings is insufficiently built, there are many restrictions in using CICS. Therefore, this study suggests a methodology to integrate and manage the construction documents and drawings by CICS. The methodology suggested in the study is verified to a web-based construction documents and drawings management system with integrated DB.

As domestic construction investment has been gradually reduced, expanding overseas construction is one of the most important issues for Korean construction companies. Among these issues, strategies for overseas CM services have widely been discussed, because the CM services have features of high growth potential and value-added area when compared with other construction sectors. Therefore, recent efforts focus on further development in advanced CM capabilities and expansion to overseas market. However, there has been lack of quantitative research to investigate current status and future direction of CM industry. In this sense, this research investigated what CM has achieved for the past 17years (between 1997 and 2013) and what CM should accomplish for future strategies. The purpose of this research is to statistically analyze total of 2,983 CM service contracts over the past 17 years published in KISCON (Knowledge Information System of Construction Industry) in order to examine current status of CM industry in terms of market type, contract size, commodity type, and owner's type. Based on this research, it is expected to suggest for future strategies and development directions from the CM industry perspective that could provide quantitative analyses, improve current CM statistics systems and strengthen the competitiveness in international CM market.
