In this study, the information breakdown structure of water purification plant has been made by classifying various the water purification methods and facilities. this can be utilized as a code system of computer for integrating information and analyzing quantitative of environmental impact and calculating cost of maintenance and energy consumption which was used during life cycle of water purification plant. Since the construction information contains many heterogeneous information, it is very important to have a code system for managing the integrated information. In addition, since water purification plant facilities are mainly composed of installation of facilities including many processes, a more detailed classification code is required. Therefore, in this study, the water purification breakdown structure which is not yet attempted in Korea was constructed by using facet classification system.

The purpose of this study is to deduct the structural damage / work process risks factors which can be occurred during the decommissioning in the NPP containment concrete structure. To achieve these purpose, risk profile specified in the construction industry is analyzed, and the work process of NPP decommissioning and the construction project were matched based on the similarity of each works. Accordingly, human and physical risk factors are classified. Finally, the risk associated with the building structure and work process was classified as per their process activities, and risk typology explaining the disaster which put the structure, equipments, machine and workers in serious danger was developed.

This study identifies various risk factors associated with activities of early construction stage, then establishes the Risk Breakdown Structure(RBS) by classifying the risks into the three groups; Common risks, risks for Earth works, and risks for Foundation works. The Common risks are identified and classified by considering various aspects of the early construction stage such as financial, political, constructional aspects, etc. The risks for Earth works and Foundation works are identified in detail by surveying technical specifications, relevant claim cases and interviewing with experts. These risks are classified based on the Wok Breakdown Structure(WBS) of the early construction stage. The WBS presented in this study classifies the works of early construction stage into four categories; excavation, sheeting works, foundation works, footing works. This study suggests a risk analysis method using fuzzy theory for construction projects. Construction risks are generally evaluated as vague linguistic value by subjective decision making. Fuzzy theory is a proper method to quantify vague conditions of construction activities. Therefore, this study utilizes fuzzy theory to analyse construction risks. The weight of risks is estimated by reflecting the interrelationship among risk factors from absolute weights obtained by fuzzy measure into the relative weights by Analytical Hierarchy Process(AHP). The interrelationship is estimated by Sugeno-fuzzy measure.

Work breakdown structure (WBS) can be used as an information center in earned value management system (EVMS) for the construction project. Because EVMS results, such as schedule variance and cost variance, are analyzed for the selected WBS code, the role of WBS code is important in EVMS. This study suggests a methodology for organizing WBS map with a quadrant. It can represent the project organization collectively by work level in a coordinate system. And the study developed an EVMS tool based on the WBS map and this tool can visualize various attribute indexes of EVMS by color symbols. Those methodologies can be used for improving practical application of EVMS.

The purpose of this study was to establish the initial computerized management database which can be applied to a universal project management computer system for managing universal project management and operation. Database construction model presented in this paper suggested the model of organization, activity and operation of bridge construction(two abutment-three-span) based on the organization information classification system of the facility classification, functional component classification, work classification, resource classification. Database model established in this study are considered to be able to take advantage of a very systematic and scientific management for future universal project management and operations.

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.

국토해양부는 지방국토관리청의 도로공사와 관련하여 발생하는 공사비 정보의 교환 및 공유를 목적으로 작업분류체계 기반의 공사비 관리 항목을 추가하여 전자설계도서 작성 납품 지침을 개정하였다. 이를 반영하고 문제점 개선 및 활성화를 위하여 5개 지방국토관리청에서 관리중인 10개 도로건설공사를 시범적용 사업으로 지정하여 발생하는 공사비 정보를 디지털 수량산출정보로 관리하고 있다. 시범사업을 진행하면서 건설공사에 발생하는 설계변경 업무를 전자화하여 관리하는 기능을 개발하고 추가 적용하였다. 이를 통해 건설사에서 생성한 설계변경 정보를 건설사와 발주처가 동일한 형태로 공사비 정보를 공유 및 관리 가능하도록 하였다.

건설업은 제조업에 비해 재해로 인한 사망률이 높은 산업이다. 대부분의 건설공사는 제조업과는 달리 고정된 생산현장이 아닌 단품수주에 의한 1회성 현장생산에 의존하고 있으므로 안전관리가 체계적으로 이루어지지 못하고 상황에 따른 임기응변적인 경우가 많다 또한 안전시설물의 설치도 매회 공사시마다 새로이 설치해야하므로 시간적ㆍ경제적 이유로 인해 소홀히 취급되기 쉽다. 건설재해에 대한 책임은 일차적으로 건설업자에게 부가되지만 건설공사 작업자의 안전에 설계자도 중요한 영향을 미친다./sup (4)/ 따라서 설계시에는 건설공사의 안전을 고려하여야하며, 공사계획시에는 공사안전관리의 대상을 명확히 해야 한다.(중략)

In domestic, the Quality Management system of construction work has been compounded of the association of regulation which is ground for relevant law and operation of Quality Management system by ISO/KS A 9001(QMS) established by the contractor. Two quality guaranteed systems must be operated with complementary and integrated system, but we can not make full use of QMS of contractor and only run routinized quality management system in all construction project by the standard, methods, process provided in the law. These problems were demanded better condition in the past ten years, since the ISO standards have been introduced. Establishing preventive consideration of quality management by setting a goal of drastic quality guarantee is an urgent problem of construction industry. This study is quick to fellow, which should do three things. 1. The attitude survey related quality management of staff in charge in construction site has run. 2. Base on these results, we adjust satisfaction measurement about operation of construction quality management system. 3. Subsequently, we want to offer our thesis about advanced opinion for the next.

Safety management for building deconstruction works has been received extremely limited attention in the domestic construction society. Lack of systematic safety management practices and defective education system lead to the high level of fatality compared to that of advanced countries. Under the above domestic deconstruction environment, the authors intend to develope an integrated safety management guidelines that covers both mechanical and partial deconstruction works. Research outcome includes such specific educational materials as safety manual, checklists, pocket pamphlets, and e-manuals. Furthermore, to validate the applicability of the above materials, questionnaire survey and interviews were conducted. Detailed descriptions are provided for each research outcome.
