This study examines the factors configuration management quality of the construction company, and to analyze the impact of these factors on Project Performance and Company Performance. That quality construction management configuration factors, chief executives, corporate strategy, organizational management, information technology, and partners five variables, Project Performance variables, process management, quality management, cost management, safety management, environmental management five variables, and Company Performance parameters of financial competence and organizational satisfaction, quality of work three variables, the overall causal relationship between the presence of specific activities and management quality, classified according to the size of the company were verified by the difference in impact between the two groups.

6 sigma is a management innovation strategy which improves most of all managerial processes including transactional and project based operations such as marketing, purchasing, accounting, and construction. Even though 6 sigma is trying to solve problems from the customer’s viewpoint in the scientific manner, project leader feels some difficulties in implementation because of several reasons. Especially the difficulties are prevalent in construction site. This paper investigates the cause of the difficulties through questionnaires, analyzes the investigation results, and verifies the critical success factors of 6 sigma implementation. Factor analysis has been usually employed in reducing quantity of data and summarizing information chaos. In this study, several variables from questionnaires are grouped into just only four factors by the process of factor analysis. The critical success factors are extracted as project management system, implementation mechanism, site condition, and project ownership. Some ideas for each individual success factor are suggested, which are expected to be useful in successful implementation of 6 Sigma in construction site.

강우로 인한 토양침식은 자연현상의 일부로 지형발달과정의 일부이다. 오늘날 증가하고 있는 인간의 개발 활동은 지표의 토양침식을 더욱 가속하고 유역의 토사유출재해를 증가시키는 원인이 되기도 한다. 특히 건설공사 중에는 대부분의 지표면이 나지로 변하기 때문에 강우에 의한 토양침식이 공사 전에 비하여 크게 증가한다. 따라서, 본 연구에서는 건설공사로 발생하는 나지사면의 토사유출량 조사를 위해 공사현장의 토양다짐 유무와 사면경사를 고려한 강우모의발생 토양침식 실험을 실시하고 토양침식에 대한 강우량, 사면경사, 토양다짐의 관계를 분석하였다. 사면경사와 강우량이 증가할수록 토사유출량은 증가하였다. 급경사 나지에서는 사면토양을 다지면 토사유출량이 감소하는 비율은 경사와 강우량이 클수록 증가하는 것으로 나타났다. 본 연구결과 건설공사가 진행하는 중에 적절한 사면관리를 통한 토사유출량 저감이 필요하며, 적절한 건설공사 지역에서 토사유출량을 줄이기 위한 사면관리에 사용될 수 있을 것으로 판단된다.
