Construction project has been more complex and bigger as various demands of the times. But current schedule management method in construction project uses only PERT or CPM made in 1950s without innovation. Also current schedule management focuses on not information flow between activities and variability of information exchanged but result. This paper suggest using the DSM(Dependency Structure Matrix) in schedule management of construction project to overcome limitations of current scheduling tools. DSM has been introduced as a new theory in construction industry in 1990s at the United States, but its application is still insufficient in domestic field due to the absence of systematic study.

In the construction industry, projects are becoming increasingly large and complex, involving multiple subcontractors. Traditional centralized coordination techniques used by the general contractors become less effective as subcontractors perform most work and provide their own resources. When subcontractors cannot provide enough resources, they hinder their own performance as well as that of other subcontractors and ultimately the entire project. Thus, construction projects need a new distributed coordination approach wherein all of the concerned subcontractors can reschedule a project dynamically. To enable the new distributed coordination of project schedule changes, I developed a novel agent-based compensatory negotiation methodology, which allows software agents to simulate negotiations on behalf of their human subcontractors. This research formalizes the necessary steps that would help construction project participants to increase the efficiency of their resource use, which in turn will enhance successful completions of whole projects.

시공을 하다가 손해를 보았는데도 발주자 혹은 원도급업체에서 인정을 안해준다면 어떻게 해야 할까? "소송을 할까?", "다음 공사는 어떻게 해. 그냥 손해보고 말지 뭐", "아니야 그냥 넘어가기에는 너무 억울해" 설비건설업을 하다보면 누구나 한번쯤 이런 경험이 있었을 것이다. 이럴 경우 공정거래위원회에 문의 하거나 건설하도급분쟁조정협의회에 문의하다가 정 안될 경우 소송에 돌입한다. 소송의 경우 대법원의 최종 판결이 나기까지 2~3년은 고스란히 걸림은 물론 소송비용도 만만치 않다. 이렇게 기간이 길지 않고 가격도 저렴하면서 해결 가능한 방법은 없을까? 물론 있다. 공정거래위원회에 제소하면 된다. 공정거래위원회는 국무총리 소속의 장관급 중앙행정기관이자 합의제 준사법기관으로서 경쟁정책을 수립 · 운영하며 공정거래관련 사건을 심결 · 처리하는 역할을 하고 있다. 정부는 지난 84년 하도급자보호 및 소비자의 보호를 위해 「하도급거래공정화에 관한 법률 」과 「약관의규제에 관한 법률」을 84년과 86년에 각각 제정함으로써 상대적으로 약자인 하도급자도 법의 보호를 받게 되었다. 본지는 지난 7월호 대한상사중재원의 '중재제도'에 이어 이번 8월호에서는 건설하도급분쟁조정협의회를 게재했고, 이번호에는 공정거래위원회에 대하여 게재한다.

This study aims to implement an efficient process management system for small and medium sized(local) construction companies and a performance management system for the Korean construction industry. The process management system by Lean Construction is Web 2.0 platform-based and creates clusters with numerous general contractors and sub-contractors, which will enable mutually organic process management. Plus, this system will enable them to compare project performance management by analyzing it during or after a project by collecting and accumulating lots of data occurring in pursuit of a project. These performance management cases will be of help in process planning during similar upcoming projects. This study is expected to somewhat reduce the burden of implementing a complicated process management protocol and system that Korean small and medium sized (local) construction companies experience with their web-based process management, and is supposed to realize accurate performance management with highly reliable data which are significantly accumulated within the database.

종합건설업체 10곳 중 4곳은 민간건설공사를 완공하고도 대금을 받지 못한 경험이 있는 것으로 조사됐다. 한국건설산업연구원은 지난해 9~10월 종합건설업체 254개사를 대상으로 민간 건설공사 불공정시태를 조사한 결과 공사 완공 후 대금을 수령하지 못한 곳은 전체의 39%로 나타났다고 밝혔다. 공사대금 미지급 원인으로는 수급자의 57%가 발주자의 지급 의지 부족과 도덕적 해이를 꼽았다. 건설산업연구원은 이같은 내용을 지난 1월 발표한 '민간 건설공사 대금 지급 및 공정성 확보방안 보고서'를 통해 밝혔으며, 민간 건설공사 도급계약 수행 과정에서 발생하는 발주자의 불공정을 개선하고 수급인의 공사대금 확보를 위한 제도적 장치 마련과 함께 건설산업의 선진화 및 경제 민주화를 달성해야 한다고 주장했다. 본지는 대금지급 지연 등 불공정 행위가 만연한 가운데 우선 원도급의 실태를 알아보기 위하여 건산연이 발간한 '민간 건설공사 대급 지급 및 공정성 확보방안 보고서 내용을 간추려 게재한다.

An integrated cost and schedule control is a noteworthy alternative of the separate control method which is commonly used in the domestic construction industry. In Korea, some cost and schedule integration models have been applied partly by construction managers. But, these models have not been customized yet because they did not reflect the characteristics of the domestic construction industry. This study investigates the characteristics of domestic integration models analyzed through interviews with experts who have the experiences in applying cost-schedule integration models. Based on these surveys, this study suggests the strategy for the improvement of work packaging model in the domestic construction industry.

As the construction site becomes larger, more complex and more special, the information of construction is expanded in quantity and specialized in quality. Therefore the computing system is necessary to effectively manage the construction schedule management. At present, main office at construction site bring in the computing system to perform the schedule management, so the data input and access for schedule management is performed by engineer on foot between construction site and main office. Therefore in this paper, we arrange wireless communication system between construction site and main of office and develop application program for data input and access of schedule management immediately using PDA at construction site. Through the our system we can improve the schedule management at construction site, and we can look forward to reduction of manpower, equipments, time, and money in whole construction.

Schedule control is an exceedingly fundamental and important construction business function. Even though enormous research efforts have been exerted in this area, there has been no comprehensive and quantitative study exploring detailed cost control practice of construction companies in terms of practical patterns and trends. In this context, this paper surveyed the patterns and trends of schedule control practice of Korean general contractors. Schedule control process as compared to schedule reduction is focused in this paper. The variables for practical schedule control process were identified first. A survey questionnaire was then developed and used in order to collect data from Korean general contractors. Survey results analyzing responses from 45 companies show that scheduling processes in practice have been significantly enhanced in terms of software tools, manuals, and capabilities of engineers.

공정거래위원회가 중소협력사와 '핫라인'을 가동, 불공정 거래행위 뿌리뽑기에 나섰다. 대기업의 일감 몰아주기 근절 및 건설 용역분야 서면실태조사 강화에 이어 구두발주, 납품단가 인하 등 불공정 거래 행위를 직접 파악하려는 조치다. 지철호 공정위 기업협력국장은 "중소기업과 공정위 간 쌍방향소통 강화로 볼 수 있다. 대한설비건설협회, 대한전문건설협회, 중소기업중앙회 등 중소기업 단체와도 핫라인을 구축했다"면서 "중소기업의 신원노출을 없애 이들의 애로사항을 신속히 파악, 대기업의 불공정 거래행위를 근절하겠다"고 말했다.

In 2011 and 2012, Korean construction firms awarded around $ 64.5. Billion each year from the overseas market in 2011. This contract value accounted for overwhelming portion of total overseas construction contract values, and this growth is expected to continue for the next decade. However, contract scopes awarded to the Korean construction firms mainly involve detailed design and construction phases due to their competitiveness for the construction techniques. In other words, front-end-engineering-design and construction project management are not considered part of core business due to the lack of project management skills and experience. The researchers focused on development of construction sequence model required to improve construction planning and scheduling skills for the Korean construction firms. The model identifies critical work items and the sequence throughout project execution process. In addition, the researchers developed a risk evaluation method by applying fuzzy theory to the critical construction activities for the industrial plant construction projects. Developed methodology will help project practitioners to develop project schedule in a timely and effe ctive manner and evaluate project risks associated with scheduling process for the industrial plant construction projects.
