The year 2008 was a hard year for Korea's construction companies. The real estate downturn resulted in halting new construction and stopping existing work, and inflation of global oil prices caused price hikes in rebar and concrete materials. As a solution to reducing the budget, the newly appointed government announced plans to increase low cost bid contracts from 10 billion to 30 billion won. When such economical and political factors negatively impact the construction market, projects based on low cost contracts are the hardest hit. Many problems already inherent in low cost bid contracts become accentuated. Consequently, this provides an opportune time to actually study and analyze the issues in these projects. This paper introduces the findings made from investigating four projects struggling to make ends meet in the year 2008. Results show that flow of cash (i.e., liquidity), or lack thereof, was the root cause which in turn was hampered by failed mechanisms for design changes, material inflation. Attributing cash flow risk to the bottom of the production structure (i.e., small business subcontractors) was also a problem within the industry. Contractors need a better way to prepare against material price fluctuations, and owners need to assist in expediting payment during times of extreme downturn.

In order to carry out construction work, it is urgent to introduce a proper wage system so that the cost burden of projects that have been won due to bleeding competition among original government buildings based on low-priced bids can be transferred to subcontractors. Purpose: Construction with illegal multi-level industrial structure needs to improve the wage reduction environment leading to order (100%) → original contractor (80%) → subcontractor (65%) → load contractor (65%) and aims to ensure wages for end workers. Method: Investigate the current status of labor cost appropriate payment plan in the construction industry, and investigate the case of the appropriate wage system (P.W) in the United States. In addition, the effect and direction of the appropriate wage system are presented. Result: Individual minimum wage security was also mentioned in the Constitution, and many researchers suggested that only the introduction of an appropriate wage system could solve the problem of reducing worker labor and ensure quality and safety. Conclusion: The proper wage system in the construction industry will block illegal multi-level and illegal foreign work, improve the labor environment in the construction market, create an influx of young workers, and have a significant impact on the construction industry's competitive structure, safety, and quality.

This study examined job satisfaction among fire protection system management workers in the fire industry and analyzed how job satisfaction affects turnover intention. The results revealed that, among the control variables, including age, rank, academic background, payment, total career, license, and tasks, significant differences in job satisfaction were found in the tasks between groups, while no significant differences in turnover were found in any control variable between groups. Additionally, the results revealed that, among the lower variables of job satisfaction, increased satisfaction with payment and organizational system affected the degree of turnover intention, while work and promotion did not. These results are to be used as data for human management of technicians and for creating alternatives. Future studies are required to establish a reasonable task rotation cycle for raising job satisfaction, to examine the current status of low-cost orders and countermeasures, and to analyze the direction of development of fire protection system management business.

Turnkey and alternative-design contracts was introduced operation in the country from january 2004 to February 2010. this was introduced operation. The selecting method of contractor for turnkey projects has being operated by an open forum type that consists of technical committee and appraisal committee in an integrated design approach deliberations. But to improve the operation of the problems, the government is operating design review committee consisting of the central, local and special design advisory committee in march 2010. But this system has also been suggested as still problems, too many contracts by large companies, increasing of design cost and excessive competition. This study is intended to contribute that turnkey and alternative-design contracts can be well operated in domestic construction markets. In this paper suggests some improvement methods and operational problems caused from application of an open forum type for selecting contractor of turnkey project.

Changes in megatrends occurring within the spatial range of the production process can be critical factors that affect the performance of unit projects in construction industry, one of the representative order industries. Although changes in the megatrend are a prerequisite for successful performance achievement, previous studies suggested methods for performance measurement and management within the production process as major results. Accordingly, this study analyzed the megatrend related to domestic construction projects and presented critical impact factors(CIFs) that can be affect a project's performance. CIFs were set by combining keywords derived by reviewing major contents of related laws and policies and future strategy reports, and the importance of each indicator was quantitatively analyzed using analytic hierarchy process(AHP). It is expected that the findings of this study can provide meaningful basic data that the various stakeholders in a construction project can refer to when establishing the strategies to achieve successful performance.

The purpose of this study is to analyze empirically the effects of changes in policies of the construction industry on the entry and exit in the construction industry and to present the direction of changes in construction industry policies based on the analysis results. The purpose of this study is also to present by analyzing the factors influencing the increase and decrease of builders in the actual construction market. The results of the survey indicate that for general contractors in Daegu and Gyeongbuk, which are mostly small and medium-sized construction companies, the strengthening of registration standards (capital, technicians, etc.) has a significant impact on market entry and exit. However, on the other hand, many of the construction policies implemented to eliminate unqualified contractors in the construction market have had the effect of increasing the number of unqualified contractors. This suggests that construction policies in the construction cycle have not achieved their objectives.
