This study is to suggest strategies of specialty contractors that provide labors oriented engineering service by interaction analysis between construction business indicators and business performance indicators. For specialty contractors that mainly provides labor oriented engineering service, the amount of construction orders imposes lasting impact to the turnover ratio of current assets supposedly because they are operating current assets to secure labor. In other words, this type of specialty contractors are focused on mobilization of labor not materials or equipment. So, it is determined that they will be able to increase revenue by operating current assets to address current liabilities and labor mobilization.

This study suggests business strategies by interaction analysis of indicators related construction business and business performance for specialty contractors that provide labor, materials and small sized equipments. To do this research, the data was analyzed for construction orders and business performance indicators of specialty contractors with KRW 7 bil. or more of assets during 1997 through 2010. For specialty contractors that provide labor, materials and smaller sized equipments, the amount of construction orders affects profitability the most and therefore some sort of strategy needs to be established to respond to decrease in operating margin due to dwindling construction orders. In other words, it is determined that increase in the amount of construction orders enhances operation of gross assets as well as the operating margin, ultimately increasing the profitability.

The recent plant order of oversea in domestic engineering and Construction Companies have been growing since 2003. In 2006, the total order came out 2.54 billion dollar. And in a quarter of 2007, the Ministry of Commerce announced that total order already came out 900 million dollar. They expect that the plant industry in the global market will be grown more in near future. However, even though there is growing plant businesses in oversea specially focused on the Middle East area, the domestic large engineering and Construction Company now face up the shortage of specialty manpower. Moreover, the domestic small and medium enterprises have same problems as large companies have. The plant construction industry is expanding rapidly, but the supply of specialty manpower can not follow its growing business. Also, most new supplied manpower is the person who graduated recently and received the degree in the different civil engineering track other than the plant major track, they are required to be re-educated. So, it is unable to deploy in short time. Also, there is shortage of manpower in the Construction Management financing division. Consequently, this project will study the efficient method of training for specialty manpower, provide the solutions.

Specialty contractor facilities, which involve a combination of welding and commissioning, face a high risk of serious accidents such as fire, explosion, and suffocation associated with welding work, nitrogen, and argon use. In such facilities, the organizational safety culture has considerable impact on the frequency of accidents. In this study, a safety culture evaluation was conducted on specialty contractors. NOSACQ-50, a standardized survey method on safety culture, was selected as an assessment tool to evaluate the safety culture in specialized construction companies that could not afford to invest heavily in safety. The self-administered questionnaire survey was conducted with 201 workers of four construction companies and the results were analyzed. It was found that in companies with low safety culture, the occurrence of irrationality was 66.0%, while in companies with high safety culture, the occurrence of irrationality was 42.6%. Thus, the difference in the occurrence of irrationality by safety culture was statistically significant. The difference in safety culture level according to the experience of occurrence of irrationality was also significant. It was also found that the higher the belief in safety management authorization, safety responsibilities of managers, worker safety priorities, and safety system effects, the lower the probability of irrationality.

The Construction Standard Production Unit(CSPU) has been used for the standard cost estimate in public and private construction projects. However, It is questionable if the reliability and/or authenticity of the system is acceptable due to the lack of consistent enactment and/or revision procedures. This study identifies informational conditions and issues relative to using daily work report as a data collection method for enacting and/or revising CSPU system, and establishes the measures for improving the daily work report. This study aims on the information constitution of daily job-site report, daily manpower report, wages register for specialty contractors. According to the research results, most of necessary data were included in a daily job-site report. In conclusion, it is investigated that data of daily manpower report and wage register need to be included in a daily job-site report for understanding the current state of worker in the future.

As characteristic of construction industries, the Issues of construction management have been pointed out because of time and space limit among construction project participants (owner, supervisor, builder, experiment specialty institute, specialty construction company, material supplier and equipment supplier). To improve these issues, procurement system has been introduced by using internet and intranet. Procurement system that was developed by some of large construction companies was considered only internal supply on closed system method. They also restricted to article supply as supply concept. In this paper, we suggest a plan to establish integrated construction procurement system that expands to the article, service and construction work supplies by utilizing the bi-directional and real-time contact system and presents related following research program.

The specialty of Construction Manager's work is largely depends on the project progress stage and the type of management work. However, at present, career management system manages only the type and duration of the construction project, disregarding specialty and competence. However, in order to select a right construction manager for the client's needs or project characteristics, career management should be subdivided and managed according to the project progress stages or the types of management. In addition, this career management plan is essential for construction managers to receive appropriate wages for their careers and competences. Therefore, this study proposes a classification system for the integration of career, work, and competency to promote effective career management.

Business boundaries of firms in the construction industry are strictly regulated in Korea. Under the current law, firms involved in construction processes are classified into five categories; general contractors, specialty contractors, architects' offices, engineering firms, and specialized in inspection. Among these types of firms, general contractors are prohibited to enter into specialty contractor's market and vice versa by the basic law in the construction industry. Also general contractors are not allowed to provide architectural services. The purpose of the law is to prohibit unlicensed companies from entering the construction market and to protect customers. However, the law causes critical problems e.g. low efficiency of production and rent creation. Therefore, we identify problems concerning business boundaries of firms in the construction industry and predict structural changes in the them when they are liberalized. So we surveyed general contractors and specialty contractors in Korea to estimate the effects of the liberalization on the construction industry. Most of contractors point to the enhancement of production efficiency as the motivation to integrate other construction process. If current regulations, which limit firms' decisions on business boundaries, are eliminated, firms will choose optimal business scopes taking into account types of contracts adopted by the Government for public works. Based on the cost/benifit analyses, they will decide whether to intergrate other production processes or not.
