  • HPC method is developing to improve the constructability and structural performance of the existing PC method. The objective of this study is to develop construction procedures and to analysis of construction period for HPC method. In order to develop construction procedures, the building construction data of the existing half-slab method was analyzed. Analyzing design drawings and specifications of nine construction cases, a prototype of half-slab method, was drawn. Applying the core technology of HPC method to the drawn prototype of half-slab method, a prototype of HPC method, was developed. The differences of both methods were 'installing PC column' and 'placing topping concrete'. To analysis the differences of both methods, seven construction cases were analyzed. According to the analysis for HPC method, cases1 and 2 had columns divided for construction shortened about 16% of a construction period. The schedule of column assembly work was analyzed to be shortened much. That is judged to be because the use of a hollow PC column leads to a decrease in the number of columns. In particular, if HPC method is applied to a building construction site using large columns, it is analyzed to shorten a construction period more than the existing Half-slab method.

  • 해외건설사업을 수행할 경우 해외건설촉진법에 의한 제반 보고제도를 준수해야 한다. 동법상 보고제도로는 $\Delta$수주활동상황보고 $\Delta$계약체결결과보고 $\Delta$시공상황보고 $\Delta$공사내용변경보고 $\Delta$준공보고 등이 있다. 또한 해외건설업체가 가장 중요시해야 하는 것은 수주활동상황보고 이다. 이 보고는 도급형 공사의 경우 입찰 예정일 10일전까지, 개발형공사의 경우 공사시행 개시일 20일전까지 제출해야 한다. 국내외 건설공사로 부터 하도급 형태의 수주활동도 마찬가지다. 현행법상 이 기일을 준수하지 않을 경우 해외건설촉진법에 의거 국토해양부는 과태료(200만원)을 부과하게 된다. 최근 신규등록업체 가운데 이 절차를 생략해 과태료 부과문제가 종종 발생하고 있다. 한편 보고를 생략하는 경우 추후 동 공사에 대한 실적을 인정받을 수 없게 된다. 현재 해외공사 상황보고 업무처리는 국토해양부의 위탁을 받아 해외건설협회가 수행하고 있다.

  • This study suggested CRMS (construction risk management system) which is a new risk analysis model after analyzing existing risk management process for to guarantee a successful performance at the construction planning and work phase. CRMS is risk management procedures in order that the contractor identify, analyze and administrate the risk during performing construction project. This model may give much help to quantify and be ready the right managing methods about identified risk by the contractor. Especially, the most important and difficult things of all risk management may be to identify risk in the project. This study make more focusing on the developing a procedure that can identify risk more easily in the construction project. The risk is divided into global risk and local risk of a project. Also, this study suggests methods which are using the RBS (risk breakdown structure) related with WBS. This result will be useful as basic materials for developing computerizing system for risk management.

  • 건설공사의 공사비를 산출하기 위해서는 공사에 필요한 노무 자재 및 장비의 정확한 투입량을 알아야 한다. 이를 위해 정부는 1970년부터 표준품셈을 제정하여 현재까지 공공기관에서 시행하는 건설공사의 예정가격 산출에 활용하고 있다. 표준품셈은 한국건설기술연구원에서 제 개정 희망항목 조사와 현장실사, 심의위원회를 거쳐 국토부에서 매년 상 하반기에 제 개정 내용을 공포하고 있다. 이번 호에는 회원사들이 궁금해 하는 표준품셈 제 개정과정에 대해 알아본다. 매년 개정된 기계설비 표준품셈은 대한기계설비건설협회에서 인쇄하여 회원사에게 배포하고 있으며, 협회 홈페이지(ww.kmcca.or.kr${\rightarrow}$자료실${\rightarrow}$각종기준표${\rightarrow}$표준품셈/일위대가표)에서 다운받을 수 있다.

  • The city planning of a local government is a continuous process that does not end with the creation of a plan but proceeds through decision-making, monitoring and evaluation phases. As a new city planning is changed and confirmed, there is a chance to construct a large scale road that is connected with an under constructed road. In this case, the expansion of the width and length of road, the addition of bridges or tunnels, and the change of the size and location of interchanges lead to many changes on road design and construction. In the past, the consignment contracts for a road construction have been made in limited numbers and for limited civil works. Now, it is growing in numbers and is making for large scale multi-works. However, the standard process and guidelines for the consignment contracts have not been suggested yet, so there is difficulty in performing the consigned road construction effectively. In this paper, the important factors for the consignment contracts are determined by construction document reviews and expert interviews. Based on these results, a standard process for the consigned contracts and a guideline for agreeing on construction cost are suggested. The costs that should be paid by a consignor are also defined.

  • Social movements to improve the performance of buildings through remodeling of aging apartment houses are being captured. To this end, the remodeling construction cost analysis, structural analysis, and political institutional review have been conducted to suggest ways to activate the remodeling. However, although the method of analyzing construction cost for remodeling apartment houses is currently being proposed for research purposes, there are limitations in practical application possibilities. Specifically, In order to be used practically, it is applicable to cases that have already been completed or in progress, but cases that will occur in the future are also used for construction cost analysis, so the sustainability of the analysis method is lacking. For the purpose of this, we would like to suggest an automated estimating method. For the sustainability of construction cost estimates, Deep-Learning was introduced in the estimating procedure. Specifically, a method for automatically finding the relationship between design elements, work types, and cost increase factors that can occur in apartment remodeling was presented. In addition, Monte Carlo Simulation was included in the estimation procedure to compensate for the lack of uncertainty, which is the inherent limitation of the Deep Learning-based estimation. In order to present higher accuracy as cases are accumulated, a method of calculating higher accuracy by comparing the estimate result with the existing accumulated data was also suggested. In order to validate the sustainability of the automated estimates proposed in this study, 13 cases of learning procedures and an additional 2 cases of cumulative procedures were performed. As a result, a new construction cost estimating procedure was automatically presented that reflects the characteristics of the two additional projects. In this study, the method of estimate estimate was used using 15 cases, If the cases are accumulated and reflected, the effect of this study is expected to increase.
