Lately Construction industry depressed by hard construction market condition. So Construction company, especial at this time, make more rationalize the management of inside Company and Construction field. So in this study we are to present the method of calculation reasonable duration at Reinforced Concrete Work. For the study first make up a question at field workers, then sampling the Form workers based the question. Second, We are using Work Analysis Method analysing the worker's work-method and Time. And then using the result of analysis, measure the Productivity of Form work. The productivity of Form work is used the basic data of duration at Reinforced Concrete Work

In recent years, pollution in residential spaces has been a significant area of concern. In particular, the indoor air quality (IAQ) of an apartment building before occupancy, which is related to the interior material, is a serious problem. Unlike previous research, which has mainly focused on pollution control after construction, this study has derived influencing factors and priority of management with a controlling schedule for IAQ. The objectives of this research are 1) control of schedule or improvement of management for IAQ, 2) distribution of responsibility to the parties concerned (factory, material company, construction company, design and engineering, occupancy). The results show the relative priority of the four major items in wall?based apartment buildings and in column?based apartment buildings. An analysis of the parties responsible for improvement based on the IAQ results shows more efforts to improve IAQ are needed in material factories and engineering/design companies.

The construction machine is the composite machine assembled by about 30,000 parts. Excavator, one kind of a construction machine, plays the leading role for export of construction equipment. It is generally impossible to produce all of the items within one company. Especially the supply of hydraulic control valves, one of the core part of the construction equipment, depends on the import heavily. So it is important to make an efficient production plan of hydraulic control valves in the company. The most important thing for the production scheduling of a hydraulic control valve is to make production schedule keeping the start date for assembly line for an excavator and to make minimization of the stock level. The production plan of hydraulic control valve includes the decision of the quantity supplied by subcontractor. This paper presents a scheme for a scheduling system of the hydraulic control valve considering the schedule of the assembly line for excavator production. This paper provides a methodology, which can make a plan of supply and production and generate a detailed schedule for daily production.

Turnkey project in construction which accounts for about $10\%$ of the total annual construction orders in the nation is expected to grow in size as an effort to strengthen international competitiveness and improve quality of construction work. However, problems of turnkey project in construction raise concern for many possible cases of possible claims. Based on the understanding that bidding guidelines which plays a critical role in turnkey project in construction actually contain some unequal clauses and causes for problems which undermine development of turnkey construction and further create possible cases of claims, the paper aims to identify and analyze the unequal clauses and problems contained in the guidelines in order to make suggestions for improvement. Among all the turnkey construction orders that has been placed since 2000 when domestic turnkey project in construction became relatively formulated, 13 constructions costing more than 50 billion won were selected for this study since their construction scale were large enough that the bidding guidelines for them were regarded as containing little difference among one another. In order to enhance construction technology and to prevent claims while trying to achieve the original purpose of Turnkey system, the parties involved in or schedule to take part in Turnkey project including ordering institution, Construction Company and Design Company should make an effort to have more reasonable bidding guidelines drawn up.

Currently, the government has made a lot of efforts to improve construction productivity but there are few studies which measure between safety perception level and productivity in the South Korean construction industry. Therefore, the objective of this study is to analyze correlation between safety perception level of domestic construction companies and construction productivity. To achieve the objective, first, the concept of safety perception level was defined. Second, the safety perception level and construction productivity were investigated in the case projects. Third, correlation analysis was conducted between safety perception level and productivity. As a result, it was concluded that a high level of safety perception of executive and manager would increase construction productivity. In addition, To improve the safety perception level in the construction company, it is suggested that the provision safety resources for managements and the equal communication system between workers and managements and the development safety education tools considering the worker's experience. In the future, these findings can be utilized to develop future evaluation tools for a safety perception level in domestic construction company.

본 연구는 정보화 수용이 상대적으로 미흡한 건설업계의 건설정보화 추진 필요성을 피력하고, 이를 궁극적인 기업성과 제고로 연결시키기 위한 목적을 가지고 진행되었다. 이를 위해 우선적으로 기업의 각 부문 최적화의 시각에서 벗어나 통합적이고 전사적인 시각으로 접근해야 함을 강조하였다. 본 연구에서는 건설업의 핵심 프로세스를 중심으로 건설정보화 추진현안을 도출하였고, 이를 토대로 건설정보화 추진방안과 향후 전개방향을 제시하였다. 본 연구를 위해 선행연구들을 통하여 건설기업의 정보화 구조모델 및 건설정보화 추진모델을 개발하였으며, 건설정보화 성공도입 기업의 임원들과의 인터뷰 등 사례연구가를 통해 본 연구 모형들의 타당성을 검증하였다. 본 연구에서는 성공적인 건설정보화 추진 사례로서 PMS 구축, 통합재무정보시스템 구축 및 CRM 시스템 구축 사례연구를 제시하였다.

최근 건설 산업은 경제성장에 따른 사회적 욕구의 다양화와 이로 인한 수요의 증대로 인하여 점차 다양화, 복잡화, 거대화되는 추세이다. 이는 기존의 건설사업의 운영으로는 감당하기 어려운 환경으로 변화하고 있음을 의미한다. 건설 산업에 내재된 불확실성과 위험요인을 체계적으로 관리하고자 하는 움직임이 대형 건설 회사들을 중심으로 나타나기 시작하였고, 특히 일부 대형 건설 회사들은 본격적인 건설사업 리스크 관리기법 도입 및 개발을 적극추진하고 있다. 이에 개별적으로 행해오던 리스크 관리를 넘어서 기업이 직면한 다양한 위험들을 전사적인 시각에서 통합하여 하나의 리스크 포트폴리오로 인식, 관리하는 새로운 리스크 관리 방식인 전사적 리스크 관리(Enterprise Risk Management)시스템이 두각 되기 시작하였다. 이에 본 연구는 전사적 리스크 관리를 건설 분야에 적용시키기 위한 첫 번째 단계료 ERM에 대한 건설 기업의 인식수준과 현 실태를 분석하고 건설 분야에서의 리스크 특성을 고려한 ERM 기본 모형을 제시하고자 한다.

The demand for super tall building construction is increasing worldwide. There has been a constant request for achieving early payback on investment by shortening the construction time. This pertains especially for the case of huge investment projects such as super tall building construction. It is very important to shorten the construction time for the building framework, which requires substantial construction time and cost, and this is directly related to the establishment of an optimum lift plan for construction. When there is a problem in the selection of the lift equipment, it is almost impossible to revise the selection, resulting in a possible failure of the project. Thus, the purpose of this study is to analyze the function and logic for the development of the process for the selection of lift equipment for super tall building projects and further development of making the analyzed process into a system. In line with this research objective, the process of selecting the optimum lift equipment by domestic construction company was investigated and analyzed as well as collecting the actual field data. The actual data were obtained by sensors installed on tower cranes at three construction sites with the help from the construction company.

공동주택 건설사업에서 건설사들은 다수의 프로젝트를 동시에 수행하고 있으며, 최적의 공정관리와 자원투입으로 프로젝트의 현금흐름을 정확히 예측하는 것은 합리적 자금운용과 경쟁력 향상을 위하여 필수적이다. 기존의 현금흐름 예측 방법은 수입과 지출요소의 차이가 크게 발생하여 정확성이 낮아졌다. 본 연구는 K 건설사의 공동주택 공사관리 실태를 조사하여 현금흐름 예측의 문제점을 파악하였다. 기존의 원가관리 시스템의 개선을 위해 업무프로세스와 공사관리 시스템의 통합이 필요하였다. 현금흐름 예측모델 구축을 위해 수입과 지출요소 및 지출방법 등을 종합 현금흐름 예측창에 표시하였다. 또한, K사의 실시간 손익실행금액과 매출기성을 산정할 수 있는 TO-BE 업무 모델을 구축하여, 수입과 지출의 부정확한 요소를 배제한 현금흐름 예측 모델을 제안하였다.
