A Case study of Life Cycle Cost Analysis on Apartment houses and Han-Ok
Kim, Keun-Woo ; Yun, Seok-Heon ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 1~6
DOI : 10.5345/JKIC.2010.12.6.001
To analyze the total cost of ownership in a building construction project, we have to consider initial plan, maintenance and operation cost, in addition to the design and construction cost. This is called "Life Cycle Cost (LCC)." Currently, it is difficult to analyze LCC because of a lack of data and the appropriate criteria. This study tries to suggest a way to analyze the LCC of building construction projects, and apply it to case studies of modern apartment houses and Han-Ok, a type of traditional Korean house. The case studies found that a Han-Ok is more efficient than a modern apartment house from an LCC point of view, in terms of maintenance and operation cost.

Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 7~17
DOI : 10.5345/JKIC.2010.12.6.007
Modern construction technology has been highly systemized, which has simplified the construction methods applied to construction sites. However, on reinforced concrete construction sites, there have recently been many new disasters, and these have been bigger than before due to the heavy dependency on manpower. This study investigates the cause and cases of disasters during reinforced concrete construction. In addition, the study surveyed the psychological condition of construction site personnel in relation to the safety awareness and the causes of disasters, while deriving the basic components related to disasters on construction sites in order to analyze the relationship between each component to suggest an efficient safety management measures checklist. Construction site personnel should utilize the results drawn from this study as a disaster prevention tool to use in a safety education class, and not consider this simply as statistical data, but as a checklist to ensure full awareness of the appropriate priorities for safety categories to utilize in the reinforced concrete construction in order to execute reasonable safety management.

Lee, Jeong-Hun ; Lee, Kyung-Suk ; Kim, Hyun-Mi ; Kim, Young-Suk ; Han, Seung-Woo ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 19~26
DOI : 10.5345/JKIC.2010.12.6.019
Advanced construction technologies have been rarely applied to practical construction operations on jobsites due to a lack of quantified evaluation data of the performance of such technologies. The basic objective of this study is to suggest a feasible way for the evaluation of the performance of new technologies based on construction simulation techniques, which have been frequently used in academic research for productivity estimation. Steel staircase systems were selected as the new technology to be investigated. The simulation was implemented in various ways, such as one staircase to six staircases on a floor. The simulation results provided in this study suggest that planners are able to make a fundamental decision on the use of targeted new technology with the estimated performance data (productivity and unit costs). These findings also indicate that a simulation technique could be one of the methods appropriate for use as a planner`s decision-making tool.
Comparative Analysis of On-site Construction Management in Korea and Japan
Song, Sang-Hoon ; Sohn, Jeon-Grak ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 27~38
DOI : 10.5345/JKIC.2010.12.6.027
Considering the similarity in legislation and long-term industrial trend of Korea and Japan, continuous attention to the Japanese situation is useful for the development of a domestic construction strategy. In order to compare the current on-site construction management practice of the two countries and analyze the reasons for discrepancy, a literature review, expert interview, and site investigation were executed. A detailed survey of experts with experience in both countries revealed that overall, Korea`s level of competitiveness is gaining on that of Japan. However, the Japanese construction industry was still evaluated as maintaining higher competitiveness, due mainly to comprehensive planning for operation, well-established design documents, and effective total quality safety environment management, all of which are combined with institutional support and a cooperative attitude by labor. Adjustments should be made for advanced technologies considering the attributes of a typical Japanese construction prior to establishing and implementing application strategies according to the suggestion of experts. Based on the results of this study, a benchmarking of Japanese strength should be conducted, and this is eventually expected to contribute to establishing green construction, enhancing safety, improving culture, and reinforcing the capabilities of participants.

Wang, Nam ; Choi, Jong-Soo ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 39~47
DOI : 10.5345/JKIC.2010.12.6.039
Top-notch global construction firms have been responding strategically in order to survive in a rapidly-changing market environment by training and securing excellent human resources. The purpose of this study is to propose a guideline for establishing a strategic human resources management system for the Chinese construction sector. Specifically, this study intends to suggest an overall strategic plan for improving the human resources management system based on the research outcomes obtained through an analysis of the Chinese construction market and human resource management practices. To meet the proposed research purpose, questionnaire survey and in-depth interviews were conducted in China. The analysis results indicated that Chinese construction firms are generally not prepared to carry out efficient training programs. In addition, the available contents and materials for education and technical training are extremely limited. Based on the problems drawn from the analysis results, an overall plan for the improvement of the education system is suggested.
Study on the Application of 3D-based BIM for School Facilities to Increase Cost Management Efficiency
Kwon, O-Bin ; Son, Jae-Ho ; Lee, Seung-Hyun ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 49~60
DOI : 10.5345/JKIC.2010.12.6.049
Cost Estimating allows each entity in a construction project to plan, distribute, and control its required construction cost for the project. However, existing 2D design based estimating has problems, such as inaccuracy and inefficiency caused by missing, duplicated, or erroneous calculations. In this situation, current estimations for school facilities have more difficulties in forecasting construction costs due to an inadequate work breakdown structure for BOQ (Bill of Quantity) and insufficient guidelines for Basis of Estimate. In this study, therefore, an effort was made to increase the efficiency of estimating for school facilities by applying a 3D modeling based BIM tool to quantity and cost estimates. In addition, this study suggested a reasonable work breakdown structure for BOQ that was appropriate when 3D modeling was applied, and verified it through a case study. The authors tried to provide a BIM-based estimating method for school facilities to obtain greater accuracy and efficiency by having more information in an earlier stage.
Study of Non Sintered Cement Mortar Using Nanoslag and Alkali Activator
Jeong, Sung-Wook ; Lim, Nam-Gi ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 61~66
DOI : 10.5345/JKIC.2010.12.6.061
As global warming has had harmful effects on the environment, the construction industry has made efforts to reduce the amount of
generated in the process of cement production. There is an urgent need for an alternative material that can replace cement. To improve the initial strength and economical efficiency pointed out as problems, this research was conducted for Blast Furnace Slag (BFS), an industrial byproduct. Non-sintering cement (NSC) was used by minimizing the amount of high-priced alkali activators. By using Nano-technology, fineness has been maximized, to enhance the initial strength of BFS. This research is based on non-sintered cement replaced by nano-slag using alkali activators, and the fundamental properties and quality of the non-sintered cement were investigated. A variety of activators were used, up to 10 percent of the slag weight. This research aims to present fundamental data through a comparative analysis of flexural strength, compressive strength, time of setting, diabetic temperature, and rising heat.

Shin, Young-Suk ; Li, Zhi-Min ; Yoo, Myung-Hwan ; Cho, Cheol-Hee ; Kim, Jeong-Sup ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 67~75
DOI : 10.5345/JKIC.2010.12.6.067
In this paper, by using steel fiber, polypropylene fiber and these two hybrid fibers, the fire resistance performance and explosive properties of High Strength Concrete (HSC) with specified compressive strength of 40MPa are discussed. The paper also examines the bending resistance of the beam and the shearing resistance properties of non-reinforced HSC beam. This research helps to clarify the fire resistance of fiber HSC and its anti-explosion methods. The test results show that crack generation, explosion and carbonization can be effectively restrained when HSC is mixed with hybrid fibers under high temperature; furthermore, the maximum internal force and ductility are increased and the initial cracking can be restrained in the mechanical test.

Yu, Il-Han ; Eom, Shin-Jo ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 77~85
DOI : 10.5345/JKIC.2010.12.6.077
Recently, with development of core technology for supertall building construction projects, the need for an improvement of the related legal system is increasing dramatically. Therefore, the supertall Buildings R&DB Center, which is funded by the Ministry of Land, Transport and Maritime affairs (MLTM), is studying the legal system for supertall buildings. This research, as one part of the 1st year research results, aimed at studying supertall building project related issues and problems to develop supertall building elements, and conducting an importance-performance analysis (IPA) of these elements in order to conclude a strategy and direction for an improvement of the related legal system. A total of 68 supertall building elements were derived, and the IPA method was used to analyze these elements based on attribute types. Furthermore, an improvement strategy and directions were suggested for upgrading the legal system related to supertall buildings to the level of global standards. These efforts can be the base for advancing the legal systems of the domestic construction industry in all areas, including supertall building construction.

A Study on Guidelines for the Repair of Water-Leakage Cracks in Concrete Structures
Oh, Sang-Keun ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 97~107
DOI : 10.5345/JKIC.2010.12.6.097
This study outlines a successful and effective plan for repairing water-leakage cracks in concrete structures. The lack of adequate solutions for water-leakage cracks often results in unnecessarily high repair costs, and as such this remains a problem that requires constant attention. Unfortunately, despite the availability of a vast number of different materials and methods, it is often difficult to attain a perfect waterproof sealing The reason for the difficulties in the repair of water-leakage cracks can be attributed to an insufficient knowledge and understanding of the negative factors (i.e., chemical and physical (mechanical) conditions) that cause water-leakage cracks, and of the properties of the repair materials and methods. In this study, guidelines and methods for the selection of adequate materials for the repair of water-leakage cracks in concrete structures were developed for countries that do not already have general guidelines on this subject, and for local regulatory authorities elsewhere.
A Study on a Strategy to Enhance the Transparency of the Bidding and Contract System for Public Construction Projects
Cho, Young-Jun ; Kim, Jong-Ouk ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 109~116
DOI : 10.5345/JKIC.2010.12.6.109
A construction project consists of many types of contracts. In the process of selecting the successful contractor after bidding, there will inevitably be fierce competition, which may lead to corruption or bribery. Even after signing the contract, during the period of settling the amount of the contract, bribery could occur. Such corruption could harm the development of the construction industry. It is, therefore, necessary to establish a strategy to prevent corruption by strengthening the transparency of the bidding process. In this study, to prevent corruption in the construction industry, a new service is proposed in which the successful bidder is selected by a professional third party, and the introduction of diverse delivery systems for construction projects and the invigoration of alternative methods of settling disputes are also proposed in this study.
The Effect of PMIS Quality on Project Management Success
Lee, Seul-Ki ; Lee, Hyoung-Lak ; Yu, Jung-Ho ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 117~126
DOI : 10.5345/JKIC.2010.12.6.117
As one of the key IT applications, the project management information system (PMIS) has played a significant role in construction management processes. This is because PMIS is an information system that gathers, integrates, and disseminates the output of project management processes among project participants, and is used to support all aspects of a project, from initiation through closing. This paper aims to identify the CSFs(Critical Success Factor) of Project Management and quality associated with Project Management Information System (PMIS) in construction projects, to analyze the Effect of PMIS quality on Project Management Success. The CSFs of Project Management and the quality components for PMIS are identified through a review of the literature, and consolidated through interviews with professionals in the construction industry. A questionnaire instrument was sent out to experienced users (Construction Manager and Constructor), and 253 completed questionnaires were retrieved. To increase the applicability of the results, the respondents consisted of workers spread across various parts of the construction site. Using SPSS 12.0, the data was used to analyze the relationship between PMIS Quality and Project Management Success through multiple regression analysis. These findings help to clarify what the highly prioritized factors are, and could also be used as an assessment tool to evaluate the performance of PMIS and thus help to identify areas for improvement.
A Case Study of the Improvement of the Structural Work of a Logistics Facility by Using PC Member
Kim, Seon-Hyung ; Choi, Eun-Gyu ; Kim, Sun-Kuk ; Lee, Sung-Ho ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 127~135
DOI : 10.5345/JKIC.2010.12.6.127
As logistics facilities have a high ceiling height, simple structure, and the need for a quick return on investment, it is usually essential to advance the construction schedule of such facilities. Accordingly, PC structures, which require less labor, cost and schedule, can be more competitive than RC structures. However, most construction companies in Korea are familiar with RC structure design, have negative perceptions regarding PC structures, and do not sufficiently adopt new construction techniques. The structure that this research features has 110 columns that are 14 m high and are built to the same specification, and applying an RC design to the structure will lead to issues related to constructibility, economic viability, project duration and safety. Therefore, this study intends to feature PC design as an alternative to the RC warehouse design, and perform a comparative analysis of the reduction in labor, cost and construction schedule to highlight benefits. The research outcomes herein will provide inputs to subsequent studies on new construction strategies to advance the construction schedule, improve quality and constructibility, enhance safety and save costs.
A Suggestion of a Target Costing Concept for Optimal Building Design
Ahn, Joon-Suk ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 137~143
DOI : 10.5345/JKIC.2010.12.6.137
Target Costing is a modern cost management technique used in changeable market conditions. The target cost is set by subtracting the sum of production costs and profits from the market price. The purpose of this present study is to review Target Costing as a useful concept which integrates the project development process with cost management. "Minimum Waste, Maximum Value" could be achieved by setting up guidelines for optimal building design at the beginning of the project development phase. This effective budget management method will help rectify Korea`s overspending problems in the area of government building construction projects.
Physical and Chemical Properties of Nano-slag Mixed Mortar
Her, Jae-Won ; Lim, Nam-Gi ;
Journal of the Korea Institute of Building Construction, volume 10, issue 6, 2010, Pages 145~154

As buildings have become higher and larger, the use of high performance concrete has increased. With this increase, interest in and use of ultra fine powder admixture is also on the rise. The silica fume and BSF are the admixtures currently being used in Korea. However, silica fume is exclusively import dependent because it is not produced in Korea. In the case of BFS, it greatly improves concrete fluidity and long-term strength. But a problem exists in securing early strength. Furthermore, air-cooled slag is being discarded, buried in landfills, or used as road bed materials because of its low activation energy. Therefore, we investigated in this study the usability of nano-slag (both rapidly-chilled and air-cooled) as an alternative material to the silica fume. We conducted a physic-chemical analysis for the nano-slag powder and performed a mortar test to propose quality standards. The analysis and testing were done to find out the industrial usefulness of the BFS that has been grinded to the nano-level.
