Timely completion and a satisfied owner are the prime objectives of a construction project. The success to achieve these objectives of a project is fully depend on the working approaches (attitude) of a contractor company. Attitude is very difficult to be measured directly; therefore it must be inferred from assumed relationship with observable indicators. Commonly, behavior shown by a person or organization represents its attitude about things or persons or issues. The aim of this paper is to develop a framework for measuring attitude of contractors in an ongoing construction project. In this paper a set of key attitude indicators (KAIs) measured both objectively and subjectively have been developed through a field survey. The validity of the proposed KAIs is also tested by four case studies. The results of the study show that the KAIs stated in the paper can reasonably measure the attitude of contractors and can be helpful for the owners and project managers to control their projects effectively. This study also provides significant insights into developing a general and comprehensive base for further study.

Clients ought to Appropriate the cost of quality management for contractors based on Construction Technology Management Act. The costs of safety management and environment reservation are separately estimated. and the quality management cost is added up to secure the construction quality required on sites. However, the sufficient cost for quality management was not allowed to the contractors, due to the viewpoints of the clients that the quality management should be one of the duties of contractors. In addition, an Account-related legislation enacted a provision of the labor cost of quality management as the one that should be included in the indirect labor cost. From the continuous survey the quality management cost is currently estimated by 0.2% of the total project cost and the contractors protest the portion of the quality management cost is insufficient. Thus, this paper aimed to provide the bases of estimation of the actualized quality management cost considering the viewpoint of contractors.

Recently many construction claims related to the ommission and discrepancy of design document are alleged since 1998 and various dispute resolution methods are appeared. But many contractors alleged claims are not satisfied with the result because of not sufficiently reflecting construction practice. The purpose of this study is to analyze the liability of contract privity from the view point of the contract related law and to analyze the claims and claim factor, and to suggest construction contract practice in the public project. The construction claims related to the design document may be minimized, through (1) the accumulation and retrieval of standard forms by owners' type, (2) the usage of specified specification considering project characteristics, (3) the materialization of detail subsurface design and various contract method in heavy engineering construction.

According to Electronic Times(2012. 1. 3), "PMO was introduced from 1950s in the USA and as of 2010, PMO participated in 84% of project ordered by public and private sector." And Ministry of public administration and security announced that the Ministry will organize Task Force for arranging "standard for introduction and operation of PMO" for support of project implementation and strengthening specialty of ordering organization, and then, actively launch the Task Force from February, 2012. Thus, necessity of PMO is regarded as natural in some aspect but thesis for doctoral degree written by Kim Gi-yeong(2007) suggested, "performance of several projects begun at the same time cannot be interpreted as high according to whether PMO team exists or not." Martin et al.(2005) asserted, "according to whether PMO team exists or not, but there is no significant difference in other factor." In the contradictory situation, it is necessary to perform more various approaches for performance and necessity of PMO in the academic aspect.

Recent construction projects consist of large and complex facilities, which project management information system (PMIS) is used for managing construction cost and schedule. The ministry of land, transport and maritime affairs (MLTM) is using a continuous acquisition and life-cycle support (CALS) system for managing the public construction projects. This study attempts to survey some problems of the CALS system in practical application, and then suggests the new functions to improve practical application of the CALS system. All functions in each menu were analyzed in the practical application aspect. All projects ordered from MLTM should use the CALS system as a PMIS, but the practical application is limited in partial functions and special working group. And the utilization of system is focused on simple tasks and report process. One of main reason is that the system is using numerical data rather than graphical data. This study suggests new functions and a visualized management method that can improve the practical applicability using a 4D object in each current functions.

The ordering organizations of civil engineering project manage the construction site indirectly because the construction site is mostly located at a remote location and the public official also manages many sites. Since the civil engineering project has a wide working area, it is not easy to know the status of the whole project quickly by the indirect management method by report of the field practitioner. In order to solve these problems, the field management system between the ordering organization and the field office is changing from offline to online. This study suggests an advanced construction site management system that obtains site-related 3D information with the use of UAV and shares the information between the construction site in remote locations and their supervising authorities. To develop an UAV application system, the problems of field management in many actual sites were analyzed and derived necessary functions such as status reporting and online information management. The developed system was applied to actual field to verify its usability and compared the efficiency improvement with existing field management method.

품질보증 활동은 제품의 품질등급을 그 규격기준에 따라 규정하고, 발주자가 지정하는 품질의 제품을 실현하는 것이지만, 압력용기 등의 특정 제품에 대해서는 공적인 제3자가 기관에 의한 검사 인증제도가 요구되는 경우가 있다. 미국에서는 압력용기 등의 규격체계는 민간 Base의 ASME Code를 중심으로 하고, 운용에 있어서의 품질보증제도는 ASME Stamp에 의한 제작공장 인증과 적검사기관을 대행하는 보험회사와의 협조에 의한 개별제품인증이 행해진다. 소위 체제 지향의 품질 관리방식을 채택하고 있다. 미국 외의 구라파제국의 이와는 상대적으로 제품지향의 제품질관리를 하였다고 할 수가 있다. 그러나 87년에 제정되어 세계적으로 확산되고 있는 ISO-9000 시리즈는 미국식의 체제지향의 품질관리로서 양자간 접근방식이 대동소이하다. 그러므로 ASME Code의 품질관리에 대하여 그 본질과 구조 및 활동 내역 등을 고찰해 보는 것은 품질관리의 시대적 조류 파악에 도움이 될 것이다.

도시철도 운영기관에서 사용되는 감시카메라 및 센서의 수는 운영기관마다 수천 개 이상에 이르고 있으며, 그 수는 지속적으로 증가하고 있다. 역사 시설뿐만 아니라 현재는 차량 내에도 카메라 및 센서를 설치하고 있거나 설치할 예정이다. 또한 도시철도의 안전에 대한 요구가 증대되면 될수록 이러한 안전설비는 증가할 수밖에 없다. 그러나 현재까지 이렇게 많은 곳에 설치된 카메라 및 센서들과 안전 설비를 효율적으로 관리할 수 있는 방안은 없다. 아직까지 폐쇄회로 텔레비전에 의존한 수동적인 감시체계에서 벗어나지 못하고 있으며, 각종 센서 등도 독립적으로 기능을 수행하고 있어 기능의 중복투자 및 비상시 종합적인 판단을 하기에는 한계를 가지고 있다. 또한 새로운 안전시스템과 기존 시스템과의 호환성 및 확장성 등에 문제를 발생시킬 수 있으며, 종합 관제실 등에서도 종합적인 판단을 실시하고 상황발생시 즉각적인 대응을 하는 데는 많은 문제점을 가지고 있다. 이를 위해 본 논문에서는 도시철도 운영기관별 정보통신시스템 현황 및 종합감시시스템 발주사양서를 비교 분석하여, 도시철도 종합감시시스템에 대한 표준규격을 도출하였다.

건설산업의 경쟁력 제고를 위해 건설산업에서 기획${\cdot}$설계${\cdot}$시공${\cdot}$사후관리단계에서 엔지니어링분야에 대한 고도의 기술력과 함께 이들을 총체적으로 관리할 수 있는 사업관리능력의 향상이 매우 중요하다. 최근 SOC사업이 대형화, 복잡화됨에 따라 전문 기술과 경험을 보유한 전문 건설사업관리 인력이 필요하고, 대형 사업의 사업관리수행방법의 형태가 발주 직영에서 사업관리 대리인인 CMr 체계로 바뀌어 가고 있다. 이와 같은 배경아래 대형 민자유치사업의 성공적인 수행을 위해서는 통합 CM/PM능력을 구비한 전략적 건설수행체제 구축이 필요하며, 이를 통해 사업비의 감소와 공기단축을 이루어 궁극적으로는 국내 건설업체의 경쟁력강화와 전문화/특화화를 이룰 수 있을 것이다. 이를 위해 본고에서는 민자사업에서의 CM의 역활을 중점적으로 논하고져 한다.
