  • 수공시설물의 홍수관리에 가장 중요한 정보는 강우자료로, 저수지 설계 및 물관리 업무에 기상청에서 제공하는 종관기상관측자료 등을 활용하고 있다. 농업용 저수지는 전국적으로 17,500여 개소로 많은 수가 분포되어 있지만, 유역내 강우관측자료의 미흡으로 저수지 인근에 위치한 강우관측소 자료만을 활용하고 있다. 저수지 유역면적은 다목적댐과 비교해 상대적으로 작아 티센법 등에 의한 평균우량값을 활용하기에 어려운 상황이다. 따라서 본 연구에서는 저수지 홍수관리에 있어 현재 제공되는 관측강우의 활용방안을 검토하였다. 이를 위해 강우자료의 활용방법으로 기존 농업용수 관리 실무에 활용하고 있는 방법과 유역 평균강우산방법의 활용성을 검토하였다. 강우자료는 기상포털개방자료에서 제공하는 기상청 지점강우, 동네실황, 초단기예측자료를 활용하였으며, 농어촌공사 홍수관리저수지를 대상으로 강우자료 활용방법에 따른 유역평균 강우값을 비교하였다. 본 연구결과는 강우예측정보를 활용한 저수지 홍수관리업무에 있어 현업부서의 강우정보 제공시스템 구축의 기초정보로 활용될 것으로 기대된다.

  • Many contractors have overlooked the construction contract general conditions and it was a bad construction practice. Today, construction project is very complex and complicated. This requires a networked contract document and results in a complicated contract conflict hardly to be solved. Therefore, to reduce the construction dispute and to enhance construction practice, clarification of definition of Owner, several conditions to be revised, insertion of design supervision were suggested in this paper.

  • In a construction project, process planning is an important factor in determining the success or failure of a project. In particular, it is necessary to systematically establish a process plan in the early stage because the finishing work of an apartment house involves more interference than the foundation work or the frame work. First, in this study the problems of Tact process management were identified, Based on the data from the case project, conventional Tact process management and compositive Tact process management were compared and analyzed. Second, cost analysis was performed on applicable plastering work to suggest the necessity and direction of compositive Tact process management. Third, the appropriateness of manpower according to the number of construction households is analyzed through cost analysis. Through this, the validity and effectiveness of compositive Tact process management were verified based on the results derived from this study.

  • The project control system based on the actual values of three objects shall be operated continuously in a timely manner. For collecting/tracking accurate actual performance data, a reasonable basis of measuring work performance and its related measuring methods are needed. Therefore, this research proposes a method of developing and operating the construction progress measurement system. The problem of the conventional method is the difficulty to construct control accounts and to define the basis of measuring the performance of each control account. Therefore, this research proposes the preferable, formal methodology that produces the progress value of the smallest work unit by surveying the installed quantities and estimates percent complete of groups of works or entire project by earned value concept. This research in connection with the hereafter research of the weight value of control accounts will contribute to apply in practice and to develop the scientific construction management technique in the construction industry. Further researches how to trend and forecast the project using the measured progress value are recommended for putting the prosed system of this research to practical use.

  • The pile foundations have been chosen more frequently as the comprehensive development of the country progressed, especially where the ground conditions are not suitable for the construction and the dimension and the length of the piles utilized becomes larger and longer. The purpose of this study suggests the improvement method of construction management for PHC pile in an apartment house. To do This, We analyzed about current process and provided improved Process with IDEF method. And, The objectives of this research is to propose the means to solve the current problems and management factors from the results of the investigation.

  • Estimation of total construction period and cost in the early stage of the project is very important. Simulation is one of the method considering proper compound such as tools, materials for effective construction management and estimating and analysing affected factors to construction through making suitable process. This study is to develop the model by using Arena simulation considering limited facts like blast time in a subway tunnel construction of both sides inner city. Developed model is easily useful type by using Visual Basic program, and can obtain total construction period and cost as a result. It could be used as a decision making tool in early stage of the construction.
