  • In this study, recently it is urgently required that recycle promotion of construction and demolition waste concrete because urban development is accelerated and redevelopment project is rapidly expanded, production quantity of construction and demolition waste concrete is being increased. On the other hand, it is urgently required that problem solution of demand and supply unbalance of fine aggregate because the sea sand is restricted by exhaustion of river sand and intensification of environment influence evaluation. Therefore, it tries to conform in time necessity, there is the objective of this study to provide the fundamental data about the re-application as the comparison and analysis the quality present condition for the recycled fine aggregate in the inside and outside of the country. At the same time it will be able to improve the quality of the recycled fine aggregate waste as investigating the physical nature and a quality present condition of the recycled fine aggregate from construction waste.

  • Strarting with Buyeong Apartment in Dongtan-2 disrict in 2017, collective complaints of residents are frequently occurring due to low quality problem such as improper construction and defects of apartment houses. Because of this, the Ministry of Land and Transport is preparing a comprehensive improvement scheme to improve the quality of Apartment Housing(AH), taking into account the continuing complaints from the residents of AH and the problem raised by the National Assembly. The basic profile of the improvement scheme is induce the tenants and experts to discover and point out defects that are repaired until the date of use inspection or due date. For this purpose, we suggested this defects management system linkaged by the preliminary inspection and quality inspection system for prospective occupants. In this context, this paper aims to suggest an effective likage method between the preliminary inspection of prospective residents and the quality inspection system implemented by local governments as an ordinance.

  • 하도급관리는 하도급업체를 전문화, 계열화하여 성공적인 건설프로젝트를 수행하는데 있다. 품질관리에서 하도급관리는 하도급업체의 ISO9000시리즈의 품질시스템의 도입에서 그치는 것이 아니라 활성화가 이루어질 수 있도록 하여 효율화를 기하고 체질 개선을 하는 것이 필요하다. 따라서 본 연구에서는 하도급자가 ISO9000시리즈의 풀질시스템을 유지하는데 저해 요인을 TQM(Total Quality Management)의 개념을 응용한 설문조사로 분석하여, 개선을 위하여 하도급관리자인 원사업자의 역할을 모색해 보았다.

  • After laws for recycling promotion of construction wastes was established on December, 2003, successive technical and institutional measures related to construction wastes are driven. Typically quality standards for recycled aggregate were enacted and officially announced, and recently the quality assurance system for recycled aggregate is promoted to be established. In relation, this study reviewed major factors affecting certification examination necessary to carry out quality assurance system for recycled aggregate and related standards to guarantee the quality of recycled aggregate. More specifically it is suggested that working place examination related to manufacturing facility and planning, quality control manpower and system, environmental and safety control, etc, and quality inspection with classified by for road construction, for concrete, and for asphalt concrete are used as quality assurance standards.

  • For the purpose of automatic management and enhancing quality of construction, information technology has been employed in construction field recently. As a consequence, informative construction, which utilizes information technology to reduce construction time and optimize construction sequence, becomes a state-of-art field of construction. Considering this case, construction field should more actively adopt other engineering technologies of rapidly advancing fields, such as electronic, control, and informative engineering, in order to reduce construction cost and to solve environmental problems as well as to enhance construction quality. In this aspect, this paper introduces a novel research field 'Geo-mechatronics', which stands for the convergence of geotechnical engineering and mechatronics (i.e. automation of mechanics using electronic technologies). Since the ground is ubiquitous in every infrastructure construction, the Geo-mechatronics research is crucial for the development of construction technology in the future. Moreover, it is believed to that the Geo-mechatronics research will make our construction industry to be more future-oriented and internationally comparative industry.

  • 한 중간 FTA가 타결되어 동북아 통합경제권 실현에 대한 가능성이 높아졌다. 중국의 고도성장은 세계경제를 주도하고 있고, 동북아권역은 세계 경제에 있어서 주요시장으로 주목 받고 있다. 또한 우리정부의 해외시장 중시정책은 계속될 수밖에 없으나, 동북아권역에서의 건설수주는 미미한 수준이며, 수익성은 일본에 비해 아직 취약하다. 이제부터는 양적인 성장보다는 질적인 성장을 추구하는 건설산업으로의 체질개선을 도모해야 하는 시점이며, 고품질의 결과물을 도출하기 위하여 품질관리에 대하여 관심을 가져야 하고, 그 기반이 되는 품질관리체계가 보다 발전된 모습으로 거듭나는 계기로 만들어야 하는 이유인 것이다. 이에 국내 건설품질관리체계를 일본과 중국을 대상으로 비교하여 경제권 통합을 염두에 둔 품질관련 체계개편과 수준향상을 유도할 발전방향을 제안하고자 한다. 또한 경제권 통합의 실현 기반이 되는 ISO 9001에 의한 품질경영시스템의 중요성을 다시 한 번 확인하는 것을 본 연구의 목표로 한다.

  • Tidal flow and water quality were simulated in this paper to assess environmental impact caused by pier construction projects in Onsan harbor system. The Surfacewater Modeling System (SMS) was applied to the Onsan harbor system, where coastal reclamation and dredging were planned to build the piers. A finite element mesh was constructed and refined to cover the complicated geometry of the Onsan harbor and the proposed reclamation area. The time variable change of tidal height at harbor inlet was given as an input condition to tidal simulation. The water quality simulation was based on the discharge rate of suspended solids at the reclamation area. The simulation results have shown reasonable agreements with real situations in both tidal flow and water quality. According to the proposed plan, tidal flow and water quality were predicted during and after the pier construction. The tidal simulation study showed that there would be no discernible change of tidal current in the harbor except for the dredged area. The water quality simulation, however, predicted that suspended solids would increase significantly near the reclaimed and dredged areas during construction.

  • Client requirements is a concept with increasing interest in relation to several outcomes of companies, and in particular, in the event of apartment project that takes large share in the domestic construction industry, diverse angle of survey is performed to discover the client requirements and reflect them to the project to improve the quality. For this purpose, it is required to learn the client requirements and apply it in the apartment project, and the QFD (Quality Function Deployment) linked ROQ (Return On Quality) is a technique used in the manufacturing that surveys the client requirements to improve the customer satisfaction, and apply it to the quality improvement program to improve the profitability in this process. In this study, through the application of the ROQ process, the plan to improve the apartment quality management is presented. For this purpose, the consumer interview survey, FGI (focus group interview) survey and the client requirements are analyzed, and thereafter, through the interview with the specialist, the quality improvement program that enables the application to the product development of new apartment product is established. Through this process, the new apartment quality management improvement plan is presented.

  • To secure quality of dam construction needs appropriate construction duration. Tight construction schedule may have negative influence on infrastructure quality, work safety and maintenance cost. It is necessary to reflect proper construction duration in the planning phase. There have been standards for estimating construction duration of building and industrial complex development but dam construction have not. In order to estimate construction duration of CFRD, feasible study reports and design reports were analyzed to acquire available information. After that, considering on construction duration methods such as comparison with similar cases, approximate estimating formula, approximate quantity assumption were adapted to Critical Path items. Hence, this study present framework for construction duration estimating of CFRD in the planning phase. This framework can be applied other types of dam along the same line.
