Korean Journal of Construction Engineering and Management, volume 15, issue 3, 2014, Pages 3~11
DOI : 10.6106/KJCEM.2014.15.3.003
Recently, remodeling construction project has been prevalently conducted in major city areas in Korea. However, remodeling construction project has a difficulty in conducting a construction because of non-existing drawing or lack of drawing information. To solve these problems, modeling techniques by using reverse engineering have been widely studied in other industries such as aerospace and automobile industry. But reverse engineering techniques have not been used in remodeling construction projects because those technology haven`t supplied less accuracy during required time for surveying. So, this study suggests optimal method of acquiring accurate 3D laser scanner information for reverse engineering at interior remodeling project.

In recent, many Korean contractors have tried to extend their business area into the overseas construction market, mainly as a result of a reduction in their domestic construction market. However in terms of risk, overseas construction projects are likely to face a number of unpredictable problems, many of which occur as a result of differences in contract cultures and construction environments between Korea and other countries. One key issue facing overseas construction projects in particular, is that of sub-contracting and control, and the way in which many countries of Commonwealth of Nations operate a unique subcontracting method well known as a nominated sub-contractor(NSC). This paper introduces the NSC system and differences as comparing among standard construction contract forms, such as JCT, SIA, HKIA and PAM. in UK and Asian Commonwealth of Nations. Also, we attempt to classify the type of the NSC system through the consideration of NSC clauses in accordance with the objection and termination of NSC contracting respectively.

Overseas construction orders of domestic companies had been increased significantly in a short period from $10.9 billion in 2005 to $64.9 billion in 2012. However experts are concerned that quality of growth will not support quantitative growth. This study suggest concentrate competencies for not only winning in bid but also successful execution of domestic companies. 4 Steps which are Pre-Marketing, Bid-Preparation, Bidding, Contract Phase are defined for competency assessment. After drawing specific tasks by phase, survey asking importance and capability of the tasks to the person in charge of bidding and site was conducted by utilizing Likert 7 point scale. According to the result of IPA analysis, domestic construction companies need to ensure internal competencies; Project risk review, Bid team organization, and external competencies; Client needs grasp, Localization strategy, Cooperation establishment. Hearafter domestic construction companies will be able to utilize the result of the study for setting bidding strategy for winning in bid and improving earning rate.

DOI : 10.6106/KJCEM.2014.15.3.031
"The Law of purchasing policy for market support of small and medium business" was legislated to support small and medium industry by expanding purchase and revised consistently for the activation. And then the government made the public construction direct purchase compulsory about design items designated by president on small and medium business based on this law. However, secureing quality, tardiness and field material staff`s heavy duty were arisen from approximately 120 direct market purchase items. The legislative intent of law is in accord with Win-Win growth between major company and small and medium business. However material staff who works in the field based on this law has difficulties with material securing quality, JIT(Just In Time), cost push. This study reclassified procurement items of "the direct market purchase system" reasonably and then suggested performance criteria for evaluation. The suggested result will contribute to vatalize the direct market purchase system.

DOI : 10.6106/KJCEM.2014.15.3.038
The Global`s top five Design Firms selected from BauNetz a German architectural magazine in 2007 designed free form building design which was 25% of the overall design by 2006-2010. Free form building is a landmark of the city and the country so its social and economic impacts are very large. In case of Korea, free form buildings such as Tribowl in Incheon, KINTEX Exhibition hall 2 and Dongdaemun Design Plaza have increased. However, those the increase in design trends and, the needs due to the lack of free form building design and construction management experience, free form building projects can`t be expected to profitability and have a number of problems after completion. Especially, there are many excessive quality problems and the rising cost due to design changes frequently and lack of experience and data. Thus an initial plan regardless of considering of free form building`s characteristics can be a huge risk because of the difference with the plan and actual projects, yet there aren`t free form building project`s performance data and case studies related to productivity. In this study, through selection of low-construction productivity works and an analysis of the work process and productivity data, hope to propose an actual field productivity of free form building and the ways to improve productivity.

DOI : 10.6106/KJCEM.2014.15.3.047
LNG plant projects tend to be implemented in overseas owing to its characteristics, so their project management scheme is somewhat different from those of general projects. Value chain in a LNG plant project includes exploration/production of gases, physical liquefaction/chemical conversion processes, transportation and storage. Key factors in the chain include liquefaction process (including ultra-low temperature liquefaction) to convert natural gas into liquid materials or fuel, and Front End Engineering Design (FEED) package, as well as Engineering, Procurement and Construction (EPC) technology comprising control, operation and construction. Success of a complex LNG plant project implemented in overseas depends on decision-making process in project management. Accordingly, to develop a decision-making model in of plant construction, the study extracted none factors in project management by EPC stage and assessed importance of each factor. The result showed that items in both project management and project risk management are important. Especially, the study developed a decision-making model in the construction stage of a LNG plant project based on the project management factors and importance assessment. The developed decision-making model would lay groundwork in building a decision-making system in construction stage of project management.

Hong, Taehoon ; Jeong, Kwangbok ; Ji, Changyoon ;
Korean Journal of Construction Engineering and Management, volume 15, issue 3, 2014, Pages 58~65
DOI : 10.6106/KJCEM.2014.15.3.058
This study aims to understand the environmental impact reduction of green buildings that are certified by Green standard for energy and environmental design(G-SEED). To ensure this end, this study assessed and compared the environmental impacts(global warning, ozone layer depletion, acidification, and eutrophication) of a G-SEED-certified elementary school building(green building) and an uncertified elementary school building(traditional building) using the life cycle assessment methodology. This study considered the environmental impacts from the material manufacturing, material transportation, on-site construction, and operation during 40 years. The comparison of the environmental impact intensity of two buildings showed that the green building generated much more environmental impacts than the traditional building. For example, the global warming potential of the green building was approximately 12.5% higher than of the traditional building since the global warming potential of the green building was 3.751
while that of the traditional building was 3.282
. It signifies that the G-SEED doesn`t guarantee the reduction of the environmental impacts in terms of four impact categories. Therefore, the G-SEED should be complemented and improved to achieve the environmental impact reduction.

DOI : 10.6106/KJCEM.2014.15.3.066
The Korean construction industry has been severely impacted by the 2008 global financial crisis, which resulted in a significant reduction in the overall contract amount. For survival, many construction management (CM) companies had to adapt a strategy of lowering bid prices to maintain their competitiveness. As a result of the strategy, companies faced a number of issues including their decreased capability in risk management. However, most risk management-related studies focused on construction risk management, yet these studies lacked consideration of enterprise-level risk management practices. To fill the gap, the objectives of the present study are (1) to investigate, the risk management practices of Korean CM companies, (2) to identify factors that determine efficient enterprise-level risk management practices, and (3) to propose a module for the development of enterprise-level risk management. Lastly, the efficiency of the proposed development module was validated by using a survey.

The proportion of apartment housing has been increased to solve the housing problems resulted from rapid growth in urban population and urban economy. With the increase in apartment`s proportions and the concern about quality of housing, the contractors have made efforts to satisfy the customers in improving the quality of housing. Despite these efforts, the conflicts between the contractor and the customers are getting serious. Also the disputes and the litigation of defect are increasing because of the contractor`s negative treatment and inadequate countermeasure. In this study the defect lawsuits which bring actions against the contractors are collected and analyzed. And then the strategic countermeasures are proposed according to the classifying the type of defect and size. The suggested countermeasure model before the defects are resulted is expected to contribute in developing the contractors strategies to reduce the conflicts against customers.

The problems of environmental pollutions and resources depletion have been growing issues in global construction recently. Efforts to reduce
emission have been also made in all sectors of construction industry these days. As one of the biggest industries that consume a huge amount of resources and generate complex construction wastes, the construction industry has significant impacts on environment issues. However, systematic approach to manage wastes has been rarely made, and most construction wastes from construction sites are being land-filled or incinerated. In this study, a system is proposed to predict the amount of wastes in visual formats, and to control the process of wastes management. The system`s main functions include : (1) to estimate the amount of wastes to be generated in project schedule, (2) to categorize the types of wastes, (3) to determine the timing of taking out wastes from sites, and (4) to share information regarding wastes for recycling. A huge amount of wastes are generated in construction process, but most of the wastes have been discharged in forms of mixed wastes, which make them hardly reused. The system not only provide information on wastes to be generated, but also prevent mixing various wastes by classifying them by types and schedules. This features of the system, along with functions to share wastes information with other agencies outside the site, are expected to enhance the level of wastes recycling to a great extent. By saving construction materials through wastes recycling, the system also contributes in reducing

Since recent construction projects become larger and complicated, the level of difficulty of management skill is rising, and the risk is increasing accordingly so the necessity of improving management skill of projects is increasing. In order to solve this problem, Construction Management system was preferentially introduced in construction projects but in case of domestic construction industry, separate contracts by business boundary are being made so the actual state is that the function of the Construction Management system is not properly operated over the overall projects. The partial operation of Construction Management system like this may impose many restrictions on converged and combined projects such as smart grid and intelligent buildings etc. in the future. For improvement of management skill of domestic construction projects, the competence of project management skill by work areas that can overcome heterogeneity of the current project management skill shall be secured, and any factor that impedes cooperation ability shall be found and that shall be solved. Therefore, the difference of work competency of project management system of construction and electrical construction is to be analyzed by utilizing IPA model in this study, and a plan to introduce the project management system of electrical construction for efficient operation of projects is to be looked into.

Baek, Byung-Hoon ; Cho, Choong-Yeon ;
Korean Journal of Construction Engineering and Management, volume 15, issue 3, 2014, Pages 113~119
DOI : 10.6106/KJCEM.2014.15.3.113
Recently, the demand on the practical application of life-cycle cost effectiveness for design and rehabilitation of structure is rapidly growing unprecedently in engineering practice. Accordingly, in the 21st century, it is almost obvious that life-cycle cost together with value engineering will become a new paradigm for all engineering decision problems in practice. However, in spite of impressive progress in the researches on the LCC, the most researches have only focused on the Deterministic or Probabilistic LCC analysis approach (Level-1 LCC Model) at design stage. Thus, the goal of this study is to develop a practical and realistic methodology for the Lifetime risk based Life-Cycle Cost (LCC)-effective optimum decision-making at design stage.
An Analysis on Economic Effects of Sectoral SOC Investment
Kim, Myeongsoo ;
Korean Journal of Construction Engineering and Management, volume 15, issue 3, 2014, Pages 120~127
DOI : 10.6106/KJCEM.2014.15.3.120
Currently Welfare is emphasized and the trend of SOC investment shows downwards slopping. The pattern of SOC investment also changes focusing on railroad as environmental issues are critical. This study analyzes and compares the effects of sectoral SOC investments based on Input-Output Tables published by BOK (Bank of Korea). The production inducement, value-added inducement, and employment inducement effects of each sector SOC, which consist of road, railroad, port, and airport, are investigated. First, in view production inducement, sectoral SOC investments have stronger economic effects than manufacture sector. The investment of port and road show the highest value-added inducement in construction process. The investment of road records the highest employment inducement in construction and operation process. The empirical ananlysis of regional economic effects, using Regional Input-Output Tables, supports these explanation showing almost same results. As synthesizing these results, the SOC stocks have to be invested consistently for long periods. Especially the road investment is inevitable for employment. Which sector of SOC is invested depends on circumstances. If government emphasizes production inducement, railroad is invested. If focuses on value-added inducement, port.

DOI : 10.6106/KJCEM.2014.15.3.128
This paper studied design of slip form system considering the erection of a pylon mock-up. The height of the pylon is 10 m. A rectangular hollow cross-section was considered. The outer and inner dimensions of the pylons were varied with respect to the height. The thickness of 1 sides among the 4 faces were varied. Accordingly the slip form was designed to respond to continuous changes in its dimensions and thickness. Structural analysis was conducted to examine structural safety of the slip form. Virtual construction by BIM proved its practicality. The developed design technologies were successfully applied to the erection of a 10m high pylon executed for field verification test.
