During the administration of a construction project, various types of participants are engaged in the project. From the design phase to the maintenance phase, these participants may confront many risks. To avoid these risks, participants should utilize an insurance company or a bond company. The types of risks and liability that a construction manager may face are listed in the construction law or contract. But there are some arguments related to risk transferring and the content of risks. For this reason, construction managers must carefully consider any possible risks in the contract and the construction law. Therefore, for construction managers to deal with risks appropriately, the introduction of a legal requirement to carry professional liability insurance, a defined compensation range for damages, a method of guarantee in the event of defects, a defined compensation claim period for damage, and a method of damage claim were suggested in this study.

Korean overseas construction has been on the rise, and exceeded the 2011 goal of $50 billion by securing $59.1 billion in orders. However, these orders were heavily concentrated in the Middle East (50%) and plant construction contracts (75%). This study suggests that, to maintain growth in foreign markets, Korea construction companies should enter into the high value-added investment development business and aggressively seek ways to diversify their regions of activity and construction types. To secure the entry of Korean construction companies into lucrative markets and better understand the competitive factors facing Korean construction concerns, a survey of the literature and focus group discussions targeting relevant experts were carried out. From those efforts, a list of 44 competitive factors crucial to entering and competing in the international investment development business was developed. Survey responses were analyzed by applying IPA. The results revealed that while Korean concerns compete well in engineering/technical capabilities, maintaining a cooperative relationship with contractors, and warranty/after sales service capabilities, their ability to obtain business information on the target country, to form private/public cooperative systems, and to build international human networks require immediate improvement.

One of recent methods to protect wooden cultural assets from fire, there is the flame retardation which is applied directly to wood and it is to prevent fire through securing flame resistance for the material and delaying combustion when failed fire in advance and then to gain time for people in the room to evacuate and it has same goal with the Korean Fire Service Act by protecting life and property. However, in case of spraying flame retardant on the colored surface of the wooden cultural assets, there are continuous problems of decoloration, efflorescence and water absorbtion after sometime and accordingly there increases danger of damages of cultural assets. So when treating with flame retardant on wooden cultural assets, there has to be no problems on dancheong after sometime and securing sustainable methods for flmae retardation should be preceded. Accordingly, this study aims to provide basic sources for selecting proper flame retardation methods by evaluating and analyzing flame retardation capabilities according to types of flame retardants which are frequently used nowadays and spraying them on the dancheong-painted surface and confirming if there is no problem on the dancheong and wood after sometime and if flame retardation effect is sustainable with its quality and capability through precise analysis.

Ko, Dongwoo ; Choi, Heebok ;
Journal of the Korea Institute of Building Construction, volume 13, issue 2, 2013, Pages 131~138
DOI : 10.5345/JKIBC.2013.13.2.131
This study was carried out to investigate the possibility of using basalt powder sludge instead of sand in a normal cement dry mortar as a way to recycle basalt powder sludge, which is a waste product from the manufacturing a process of basalt in Jeju. Basic performance evaluations of the dry mortar material included a compressive strength test, a flexural strength test, and SEM to observe the micro structure. The compressive and flexural strengths were increased to a replacement ratio of 21% of basalt powder sludge, whereby a strength enhancement of about 40% greater than that of normal dry mortar was shown. However, the creation of hydration products affected the replacement ratio of the basalt powder sludge. The possibility of using basalt powder sludge waste was identified in this study, and results showed that the basalt powder sludge waste could be used as a material for a secondary product of concrete.

The purpose of this study was to investigate the durability performance of concrete that includes rice husk ash. Chloride diffusion coefficient obtained through a rapid chloride penetration test and depth of
penetration obtained through a rapid carbonation test were used to evaluate latent durability. Durability characteristics for rice husk ash replacement and age were determined. Through the experiment, it was found that when the replacement ratio of rice husk ash was increased from 0% to 10%, the compressive strength of concrete containing rice husk ash was similar to that of concrete containing silica fume. This shows that the durability performance of concrete containing rice husk is excellent compared to other concretes containing admixtures.

Generally, building construction projects have a complex decision-making process because of the participation of various agents. In this situation, a final decision is arrived at by relying on subjective judgments based on the experience of project participants. For this reason, a method of assessing the objectivity of opinions is needed. In previous studies, the multi-criteria decision making method was applied to arrive at a final decision objectively, but this method has a limitation, in that the experience of each decision maker is not considered differently in the decision making process. Therefore, this study proposed a theoretical model using the S-shaped growth curve and regression analysis by building construction project type to quantitatively estimate decision-making reliability according to the experience of individual project participant`s. The developed model could be added to the Multi-criteria decision making method, and secure the objectivity and reliability of project participants' final opinion.

Construction projects have become increasingly complex in recent years, resulting in substantial safety hazards and frequent fall accidents. In an attempt to prevent fall accidents, various safety management systems have been developed. These systems have mainly been evaluated qualitatively and subjectively by practitioners or supervisors, and there are few tools that can be used to quantitatively evaluate the performance of safety management systems. We propose an expertise-based safety performance evaluation model (EXSPEM), which integrates a fuzzy approach-based analytic hierarchy process and a regression approach. The proposed model uses S-shaped curves to represent the degree of contribution by subjective expertise and is verified by a genetic algorithm. To illustrate its practical application, EXSPEM was applied to evaluate the safety performance of a newly developed real-time mobile detector monitoring system. It is expected that this model will be a helpful tool for systematically evaluating the application of a robust safety control and management system in a complex construction environment.
Developing the Path Model defining the Relationship between Construction Worker's Personal Characteristics and Safety Behaviors
Jin, Hyeong-Seong ; Lee, Dong-Eun ;
Journal of the Korea Institute of Building Construction, volume 13, issue 2, 2013, Pages 169~180
DOI : 10.5345/JKIBC.2013.13.2.169
This paper presents the path model that defines a causal relationship between the construction workers' personal characteristics and their safety behavior at job-site. The personal characteristics and the safety behaviors which should be incorporated into the theoretical model were identified and established by conducting literature survey.. The model was verified by administrating survey questionnaires to the 399 construction workers who are actively engaged in construction job-sites located in Daegu metropolitan city and Kyungpook province. The data obtained from the respondents were statistically analyzed using SPSS18 and AMOS18. It is confirmed that safety behavior is directly affected by sincerity, openness, and extroversions. In addition, it is indirectly affected by stress reaction, safety motivation, and safety knowledge as well.

Given both structural safety and economic benefits of aging facilities, remodelling of the existing facilities is preferable to reconstruction. This recognition provides an opportunity to reduce the commitment of resources and national budget. However, when a subordinate troop asks for remodeling or reconstruction of a deteriorated facility, it is difficult to ensure the consistency and objectivity in the process of decision making for the alternatives due to the absence of systematic and quantitative rating methodology. Their economic evaluation methodology only exists in a manual format. Thus, further research is required for converting the methodology into an automated system in view of practicality such as rapid and accurate data processing. The contributions of this study are as follows: 1) Literature review found out a representative economic evaluation model focused on military facilities, and comparative analysis with a similar study identified the strength and weakness. 2) this study presented how to convert the theoretical framework which enables to solve a specific subject matter into an automated system. 3) it developed a user friendly interfaces which consist of four functional modules by considering the usability and accessibility of the system user. 4) the developed system was verified by a case study in terms of four kinds of performance indicators.

Recently there has been insignificant growth in the Korean construction management (CM) market, in comparison to the previous year. However, despite stagnation or even decreasing growth trends, the number of domestic companies participating in the CM market has increased rapidly. As follows, market movements of CM despite trending in stagnant growth or decrease, the market has been increasing firms which entry the market. The reasons for such dynamic change must be examined first, in order to facilitate analysis of its competitive structure. This study aims to examine the market competition structure and analyze the reason for proliferation of companies in the sick CM market. This study employs market concentration ratio and DEA-based Malmquist productivity indices to analyze the competitive structure of the CM market. Results reveal that the CM market has been monopolized by a few companies, but this is gradually changing. In addition, these companies were not productive, but there has been a gradual increase in the productivity index. Therefore, this study, which provides the direction index of the CM market, has implications for all major stakeholders in this market.
