Owners, local autonumous entities, have a burden on operating project for the lack of their management capacity such as specialty and human resources. In this reason, they want to perform project with CM methods. But there have been only a few case of CM operation and application in a huge construction project. The complex formations of CM and responsible management are used in those project. This situation originates in the lack of CM specialist. Because the CM service used in those case is generally performed as the mixture of responsible management service and design management service, it is not the prototype of CM. The purposes of this study are to present the solutions to the problems concerned with the design development phase management, design phase VE, the application of Fast-Track, PMIS operation and CM execution, etc, and establish the plan to perform CM services efficiently in the public sector through analyzing the case of CM application in Gwangjin-Gu Culture & Sports Center.

In 2011, the overall construction markets in KOREA are highly depressed due to decreases in orders of domestic construction markets in both private and public field. Also, we are losing competitive advantages over Chinese and Indian companies owing to the market shares on plant construction projects excessively. It is recognizable, under the circumstances that we are in interior position on high value technique to other advanced countries, that the orders of mega building and plant construction projects tend to be placed through the" Pre-construction Service", the importance of which has been emphasized domestically and internationally in recent time. However, current domestic construction companies show scarcity in understanding the general idea of the Pre-construction Service and fail in building proper structure of it. It is obvious that they cannot have any competent strategy to deal with Pre-construction Service. The Purpose of this paper is to analyze the core competence throughout preconstruction phase and, and make up for the weakness in the current pre-construction service process.

This study proposed a framework for an infrastructure asset management manual which can be adjusted by different ordering authorities to develop their own manuals. For this, The necessity of asset management manual was examined through analysis of the current status and insufficiencies and limitations in the asset management manuals of the domestic government and ordering authorities. Second, the systems and characteristics of infrastructure asset management manuals in developed countries such as Australia, the United Kingdom and the United States were examined and compared. Finally, based on the domestic infrastructure asset management characteristics and foreign infrastructure asset management manuals, a framework for an infrastructure asset management manual that can be utilized by the ordering authorities was proposed considering generality of asset management manual, asset management maturity of ordering authorities, serviceability of manual, and cyclic processes of asset management.

For the purpose of analysing the capability (knowledge, experience, and ability) of CM at Risk in the major construction company in korea, this study performed questionnaire survey with experts in the companies. Based on the analysis of the survey, the study was found as follows. 1) It is needed to increase the capability of preconstruction services, such as project management plan/manual, contract documents, value engineering, alternative analysis, time management, and claim. 2) Despite of gap of the capability between the present and the future CM services, the study concluded that the capability is sufficient to perform CM at Risk project in the major construction company.

VE is one of the most effective and systematic tool available to achieve the required function at minimum cost and manage in many industrial fields. The purpose of the preparation phase VE job plan is to establish a cooperation system referring to groups for the successful implementation of VE, and to achieve a common objective to collect sufficient materials required in the analysis phase. The Quality Model is used to measure the requirement of shareholders(users and owners)in the project. It also offers a guideline on decision making when executing the function definition, function arrangement, function evaluation, and the idea evaluation of VE. However, the current the preparation phase business confirms that the required items of owners and users has not suggested definite goals and directions. This study analyzes the problems of current work in the preparation phase from case study, survey and interviews of experts. It then proposes a new process after understanding the required items of owners, users and experts.

To establish an infrastructure for technology and information in the domestic construction industry, several construction regulations pertaining to construction information have been institutionalized. However, there are major problems with the domestic information classification system, earned value management (EVM) and project management information system (PMIS). In particular, the functions of the current PMIS have consisted of a builder-oriented system, and as EVM is not applied to PMIS, the functions of reporting, analysis and forecast for owners are lacking. Moreover, owners cannot confirm information on construction schedule and cost in real time due to the differences between the EVM and PMIS operation systems. The purpose of this study is to provide a framework that is capable of operating PMIS efficiently under an e-business environment, by providing a proposal on how to establish a work breakdown structure (WBS) and an EVM - PMIS integration model, so that PMIS may provide the function of EVM, and stakeholders may have all information in common. At the core of EVM - PMIS integration is the idea that EVM and PMIS have the same operation system, in order to be an activity-based system. The principle of the integration is data integration, in which the information field of an activity is connected with the field of a relational database table consisting of sub-modules for the schedule and cost management function of PMIS using a relational database management system. Therefore, the planned value (PV), cost value (CV), actual cost (AC), schedule variance (SV), schedule performance index (SPI), cost variance (CV) and cost performance index (CPI) of an activity are connected with the field of the relational database table for the schedule and cost sub-modules of PMIS.

본 논문은 내륙 운송 체계 하에서 공 컨테이너의 효율적인 재고관리 문제에 대하여 다루고자 한다. 그리고 실제 컨테이너 선사가 공 컨테이너 운영 관리에 있어서 예측하기 힘든 고객의 수요 및 공급 등의 불확실한 요소들을 고려하기 위하여 공 컨테이너의 수요와 공급을 확률변수로 가정하였다. 이러한 가정을 바탕으로 시뮬레이션을 통하여 재고유지비용, 임대비용 및 총 기대 비용을 추정하고 (R, s, S) 재고 정책을 기본 재고정책으로 한 가정 하에 GA (Genetic Algorithm)를 사용하여 총 기대 비용을 최소화 하는 주문, 발주 정책을 도출하고자 한다.

Domestic and foreign software components are rapidly developing continuously. However, the government's plan to activate BIM remains relatively sluggish. In particular, BIM based information management systems have been developed to enable the development of degraded railway industries in infrastructure BIM based areas. For this purpose, we analyzed domestic and oversea policies and guidelines. We conducted a survey on the personnel of the railroad corporation. Based on the survey result, the elements applicable to BIM were reflected in the system.

Mechanical facilities in modern buildings and industrial plants become more important in the view points of energy and environment issues. However, mechanical construction fields are still considered as to be subjected to buildings, even though design and construction of mechanical fields in the construction production process is independent of other fields. Recently, 'Framework Act on the Construction Industry' has been revised since 2007. According to the revision, the barrier of general construction and specialized construction is collapsed and the construction company can register any type of construction classification if they are able to carry out the construction mission. The mechanical construction fields are exempt until 2011 because of the protection of mechanical construction industry. In the present study, the bidding system has been prospected due to the revision of 'Basic Law on Construction Industry' after 2011. The trends for development of mechanical construction fields has been also discussed.
