General contractors' overhead costs are increasing relative to direct costs. However, it is difficult to apply the traditional activity-based costing directly to the construction site overhead costing because the resource consumption rate per each activity is varied depending on the attributes of activities. The research develops a methodology of hybrid cost allocation system when resources are assigned to cost objects unlike the traditional activity-based costing. The study also develops a database program and demonstrates how it can be applied to the construction projects using a case study.

정부 재정지출의 효율성 제고를 위해 도입된 총사업비관리제도는 그간 대형 신규 공공투자사업 추진 시 적정한 절차를 순차적으로 거치도록 의무화하고, 총사업비 증가율을 억제하는 등 일부 성과가 있었다. 도입 18년이 지난 시점에서 공공건설사업의 사업비 관리의 근간이 되는 총사업비관리제도에 대한 적용 실태 및 제반 운영에 대한 사업참여자들의 인식을 조사하고, 설문을 통하여 운영상의 문제점을 도출하여 이에 대한 개선방안을 제시하였다. 기본적으로 공공건설사업의 사업비 관리는 사업 초기 단계에 예산을 정확히 산정하고, 후속 단계에서 이를 지키려는 노력을 시행하며, 확정된 예산에 가장 부합하는 사업의 가치 확보라는 개념에 입각해서 계획하고 관리하여야 한다. 공공건설사업의 총사업비관리의 체계화하고, 담당자의 전문성을 제고하는 한편 발주처의 자율성을 확대하여야한다. 무엇보다도 총사업비관리 대상사업의 적기 준공을 유도하여 사업기간 지연으로 인한 총사업비의 증액을 방지 할 수 있는 여건 조성이 필요하다.

Civil engineering construction work has always been accompanied by a high proportion of tasks that are either dangerous or unpleasant or both. Enhancing the general working environment and boosting safety levels are critical issues for the industry. In addition to that, the industry has been slow to utilize automation & robot technology, and there is substantial scope for the use of technology th boost efficiency, cut costs and improve quality levels in construction. In a bid to address this issue, Ministry of Construction & Transportation launched a five-year project in 2003 entitled Development of Intelligent Excavating System. The aim of the project is to use telecommunications and robotics technology to minimize inefficiencies and eliminate the dangerous and unpleasant aspects of tile construction process through the development of specific applications such as IT-equipped construction machinery and advanced construction management systems. In this paper, the project introduces on the research and development content related to multi-disciplinary, a intuitive operator control unit(Robot Technology) included.

While the idea of the existence of a set of key factors for success in planning, designing and construction of projects is not new, it remains one of the most important issues in the field of construction management. This is due to project success factors are inputs to project management practice which can lead directly or indirectly to project success. This study identifies the success factors which can be used for improving the highway projects performance in Egypt during the project pre-construction and construction phases. Through a detailed literature review 35 success factors are identified. Furthermore, the AHP is adopted to prioritize the studied factors through the application of questionnaire survey. The study establishes that implementing an effective quality control and assurance systems, allow sufficient time for feasibility studies, design, drawing and tender preparation, effective cost control system and frequency of project budget updates, preparing adequate designs and drawings and determining sufficient time to implement the desired scope of work are the most important success factors for enhancing the highway projects performance in Egypt.

건설공사관리체계는 실적자료를 바탕으로 운영되어야 하며, 공사실적을 정확하게 파악하기 위해서는 합리적인 건설공사진도 율 측정기준 및 그에 따른 진도 율 산정방법이 필요하다. 본 연구에서는 건설공사관리체계 구축에 필수적인 건설공사진도율 산정시스템 개발 및 그 시스템의 합리적인 운용 방안을 제시하였다. 그 방법으로서 분할된 단위작업들은 공사 진행에 따라 집행된 내역물량을 기준으로, 상위레벨의 작업범위에 대하여는 실행기성(earned value)을 바탕으로 건설공사의 진도 율을 산정 할 수 있는 시스템(construction progress measurement system; CPMS)을 제시하였다 일반 PC의 Window환경에서 제공되는 프로그래밍 인터페이스(interface) 기능인 ODBC(Open DataBase Connectivity)는 상이한 프로그램간의 데이터 교환을 통해 정보공유를 가능케 하고 있다 본 연구에서 제시하는 건설공사진도 율 산정 시스템은 ODBC를 통해, 상용 일정관리프로그램을 활용해서 생성된 데이터를 그대로 이용하고, 시스템 내에서 생성된 데이터는 일정관리프로그램에 갱신(update)된 정보로 제공된다. 제안된 건설공사진도 율 측정시스템의 실용화를 촉진시키기 위해서는 진도 율 측정에 의한 수치 값을 분석하여 향후 공사의 전망 등을 예측할 수 있어야 하는데 이에 대한 연구가 필요하다.

Through the case study, we surveyed the performance of a CNC-T BAR system on irregular-shaped building construction project. By CNC T-BAR system, we mean a surface curvature control system has been used in aircraft and ship manufacturing by controlling entire surface points on shape. For the past 10 year, the number of irregularly-shaped building design and construction project has been increased, and also the studies on irregular-shaped construction methods have been conducted. However, the previous studies did not review on the performance of the CNC T-BAR system. We collected construction-completed cases in Korea, which applied the CNC T-BAR system, and we studied its performance by comparing with a segment system in terms of construction duration and its quality. The result shows that the CNC T-BAR system can shorten the construction duration comparing with segment-assembly system while maintaining high quality. The CNC T-BAR system is expected to apply on the more number of irregularly-shape building construction project.

A number of documents containing important and useful knowledge have been generated over time in the construction industry. Such text-based knowledge plays an important role in the construction industry for decision-making and business strategy development by being used as best practice for upcoming projects, delivering lessons learned for better risk management and project control. Thus, practical and usable knowledge creation from construction documents is necessary to improve business efficiency. This study proposes a knowledge creating system from construction documents using text mining and the design comprises three main steps - text mining preprocessing, weight calculation of each term, and visualization. A system prototype was developed as a pilot study of the system design. This study is significant because it validates a knowledge creating system design based on text mining and visualization functionality through the developed system prototype. Automated visualization was found to significantly reduce unnecessary time consumption and energy for processing existing data and reading a range of documents to get to their core, and helped the system to provide an insight into the construction industry.

The supply chain in plant construction project can be defined as a network combined between elements which is engineering, procurement, construction, start-up. For successfully leading construction project, close relation and mutual cooperation should be preceded and Supply Chain Management(SCM) system is needed to improve the relation. In particular, because safety is a top priority for the companies work in the construction of Nuclear Power Plant(NPP), it is necessary to control all parties realated with NPP construction systematically. In this situation, it is important to purchase high-quality equipment in timely manner by developing Integrated cooperative systems. Therefore, this study aimed to propose developing solutions of SCM such as JIT and Envelop Design system, which can reduces difficulties of decision making between the parties involved in the project and will increase the efficiency of the engineering process in NPP.
