  • In this study, life cycle cost (LCC) is analyzed according to insulation panel system type using a deterministic LCC analysis method. Through this analysis, it was found that the construction cost in the deterministic LCC analysis for Ceramic panels was low compared to the construction cost for metal and stone panels. Also, the difference in cost between the Ceramic panel and the metal panel was about 2 times. In the area of maintenance cost, it was found to be similar to the previously analyzed construction cost, in which the metal panel has the highest cost due to the high cost of construction and the frequent need for maintenance. In the case of the stone panel, a small difference in cost is shown compared with that of the Ceramic panel, but the cost is higher than the Ceramic panel. Regarding the cost of waste disposal, the Ceramic panel can reduce the cost by at least 1.5 times and up to 2 times compared to other panel systems. Finally, in the analysis of sensitivity according to changes in discount rates, the Ceramic panel and metal panel systems have a similar cost, and the cost of the metal panel is a bit larger than that of other panel systems. Thus, in the subjects used in the analysis, the Ceramic panel system shows the highest economic benefits.

  • Recently, with achieved US$ 500 Billion international cumulative construction order, the Korean government presented overseas construction industry visions for international orders of US$ 100 Billion and entering the top five countries in global construction market. Also, Korean companies are developing strategies for expansion of international markets. However, ODA loan projects are low risk for the Korea Construction companies trying to advance their overseas business. This study provides data-based advice on securing competence for Korean construction companies entering the global market through the ODA loan projects. To analysis construction firm's competitiveness for ODA loan project, FGD was utilized and BSA model was applied to the valuable analysis. Competencies highly assessed were construction quality control, relationship building through high-level diplomatic activities, and project management. Competencies requiring urgent improvement were handling risks of local countries, financing projects, and developing know-how within participating companies.

  • The changes in business structure of domestic construction companies suggest that there is a close relationship between the volume of overseas project and a company's financial condition. Based on this assumption, this study conducts an empirical analysis on a relationship between overseas project and financial stability of a construction company. The ratio of liquidity and liability was used as liquidity index and stability index respectively. The analysis was based on quarterly time-series data between 2000 and 2010. Two models were constructed for the analysis: Model 1 was based on the liquidity ratio and the amount of domestic and overseas construction project; Model 2 was based on the debt ratio and the amount of domestic and overseas construction project. The analysis results showed that the increasing amount of overseas project facilitated short-term financing with greater liquidity, and yet it was not very effective in lowering the debt ratio. This suggests that the dramatic increase in overseas construction project, which is observed recently, is not entirely an optimistic sign.

  • Construction companies do not take necessary steps for sudden change in the Construction market, In order to over come the problem, it is necessary to make Corporate Strategy through correct Market analysis. If construction companies want to secure continuance profits, they must prepare proper strategy to advance into plant market. This research performs both external and internal environment analysis, External environment analysis is for overseas construction market and advanced foreign companies, and internal environment analysis is the current status of domestic companies. The research identifies some of the Key points, growth in foreign plant market is huge, but domestic companies do not have abundant construction experience on the same field and also they lack in high value-added techniques. They are far behind the advanced companies; they don't have proper skills of Procurement, engineering and project management. This study suggests a strategy for domestic companies to take necessary step to advance into plant construction market.

  • Korea's population change trend is the aging and feminization as Reduction in mortality, average life extension. and is further increased Reduction of birth rate and aging population. if Our country concluded FTA(Free Trade Agreement) with the United States, Europe and China etc. labor-intensive industries will be the decline. Then, the construction workers' jobs are continually reduced. This is critical to the nation's economic, social and environmental influences due to Shortage of construction workforce and increasing labor costs. Eventually this is a major factor in reduced construction productivity. Therefore, this study is presented as a construction productivity development prospects on the value-added analysis per Labour productivity employee from Construction market trends, industry-specific productivity index, industry trends Employed, age tiered workforce trends, women's workforce trends, labor time trend, foreign workers, workforce trends, analysis of trends in construction contract, awarded by Company Size trends, construction management analysis index.

  • Due to the increasing demand for and complexity of plant construction projects, unpredictable risk factors are on the consequent increase. For that reason, the quantitative risk analysis is being called for, in order for the development of a risk assessment model using risk indicators for the plant construction projects. This study used the claim payout data collected at a global insurance company to reflect the actual financial losses in plant construction projects as dependent variables in the risk assessment model. In terms of independent variables, the geographic information, i. e., landform, and the construction information including test-run, schedule rate, total cost and duration are adopted. In addition, this study suggests that the regression model containing such independent variables that are statistically significant can be applied to as a foundational guideline for the plant construction project risk analysis during the phase of construction and commissioning.

  • Building construction education requires training and experience. While there have been many means of education, virtual reality (VR) can be applied as a complement for building construction education. Considering the characteristics of building construction education, interactive content based on VR technology is expected to raise the effectiveness of traditional education. This research conducted a survey to examine the applicability of VR technology to building construction education and provided basic information by prioritizing work types for educational content.

  • This study aims to estimate the relative importance of quality management items through the defect analysis in the landscape construction process. The RIQMI are decided by the defect coefficient and it's cause weight. The defect items in the landscape construction process were classified by 56 items based on the classification form of '96 landscape architectural construction standard and the cause pattern were categorized 4 types as design, material, construction, and environment factors. To analyze the defect coefficient and the aucse weight by defect, the researcher surveyed the questionnaires on the 103 engineers and the 31 experts on the landscape architectural construction. The result of this study are as follows. The relative importance by facilities pattern turn out to be much higher construction, material fator than design. environment factor in wood facilities, paving facilities, and steel facilities, the RIQMI is very high in timber crack, timber vending, faulty of timber against decay, welding faulty of steel facilities in material factor, and timber crack, faulty of timber against decay, finish faulty of steel facilities, welding faulty of steel facilities in construction factor.
