The purpose of this study is to establish a novel system for on-site management of construction and demolition waste. Construction waste has always been one of largest waste in the world and has long lacked an effective management system. Although various countries have planned the disposal of waste at the political level, the real-time and effective management of construction sites has not been mentioned. Especially in China, the continuous development of the construction industry also generates a large amount of waste, and China is not prepared for a large amount of construction waste. In order to alleviate the huge impact of construction waste on society and the environment, this study proposes a waste management method that combines Building Information Modeling technology and Radio Frequency Identification technology. Through this research, by using information technology to manage the generation and discharge of construction waste, and record the amount and information of waste generation, also improve the management method of construction waste.

건설산업에서 폐기물 관리는 환경적${\cdot}$경제적 측면에서 중대한 영향을 미침에도 불구하고, 건설폐기물 관련 통계자료에 의하면 국내 건설폐기물 관리 수준이 상대적으로 낮음을 알 수 있다. 이에 따라 본 연구는 건설폐기물 관리의 요체인 건설폐기물 관리 지침을 고찰하여 문제점을 분석하고, 효과적인 폐기물 관리를 유도하는데 적합한 건설폐기물 관리 지침 개선 방향을 제시하고자 한다. 국내 기존 건설폐기물 관리 지침을 분석한 결과, 폐기물 관리의 목적이 총체적으로 법적인 기준을 벗어나지 않도록 관리하는 데 초점이 맞추어져 있음으로 인해 분석 기준인 "계획, 실행 및 운영, 점검 및 시정조치" 측면에서 효과적인 폐기물 관리 지침으로서의 역할을 다하고 있지 않음을 파악하였다. 또한, 문제점 분석 결과를 기반으로 "계획, 실행 및 운영, 점검 및 시정조치" 측면에서 국내 건설폐기물 관리 지침의 개선 방향을 제시하였다.

Recently, it is necessary to establish an eco-friendly construction system through recycling of waste material management at construction sites. This is required to reflect the times that require a carbon reduction system in construction as part of domestic and overseas carbon dioxide reduction. Therefore, we intend to establish eco-friendly construction management as part of resource recycling and carbon reduction through recycling technology for waste fibers generated at construction sites.

This paper shows construction management focused on waste management in construction project in planning stage Construction waste is given a great deal of weight on total waste. And it is issued in government policy. But it show the limit of problem.As a result of having referenced idea as describe above, this paper will be studied by this process. First, present condition of development waste, cases is researched in construction projects. Second, problems of development pattern and management system are investigated and checked in project cases. Third, maintenance and management method project are proposed by application of planning Stage.

Construction management has been suffering from many problems, which need to be solved or better understood. Most of construction projects have not achieved efficiency as expected. In this context, waste was also considered as a problem of efficiency decrease, and poor production planning was considered as a cause for waste. This study was conducted on the basis of waste concepts and production planning processes based on the philosophies of Lean Construction. A survey to find out the relationship between them was carried out through questionnaire, which was answered by experienced people in construction projects. The results have shown that frequency of wastes occurrence is quite high, and production planning processes are superficially performed in construction phase. There is a significant negative relationship between production planning and waste occurrence (r = -0.262). Weekly Work Plan (WWP) is the most dominant plan for waste control with seventeen in total of nineteen waste factors, and phase plan is the most dominant plan for two remaining waste factors. A case study was adopted to validate the relationship between production planning and waste occurrence. The results showed that the better the project was planned, the fewer the waste would occur on construction sites.

It is needed to classify the kinds of construction and demolition(c&d) debris to 6 catagories of waste concrete, waste asphalt concrete, waste wood, scraps, combustible waste and incombustible waste in order to properly do a separate discharge and to estimate unit generation rate in construction site. Also, in this case, the unit treating cost for mixed wastes should be applied with the unit treating cost for combustible waste. The construction standard materials estimation data is used for basic data for estimating unit generation rate. The mixed wastes in this data should be classified to waste wood, combustible waste and incombustible waste, and their ratio is obtained by using the unit generation rate of Asia Pacific Environment and Management Institute and Seoul Metropolitan Development Institute. The waste amounts generated from newly-built construction can be obtained from multiplying the loss rate by the amount of materials used from construction standard estimation data. Also, those from dismantling construction can be obtained by subtracting waste amount generated during newly-built construction from total input amount of materials in newly-built construction. Those in two cases can be used in construction site. It can be used for estimating the amount generated and establishing the treating plan in the case of setting up the policy of waste management and doing the environment impact assessment.

국내 폐기물 발생현황을 살펴보면 건설폐기물의 발생량이 44.6%로서 가장 많은 비중을 차지하고 있으며, 변화하는 사회 환경에 맞추어 건설공사의 규모도 점차 대형화되어 건설폐기물의 발생량은 꾸준희 증가하고 있는 실정이다. 지금까지 건설폐기물 처리 및 재활용 비용이 전체 공사비의 0.5%에서 1%정도 차지하고 있지만, 각 건설현장에서 건설 폐기물을 효율적으로 관리하지 못한다면 전체공사비에서 건설폐기물 처리 및 재활용 비용이 차지하는 비율은 더욱 높아질 것이라고 예상되고 있다. 이는 건설폐기물로 인한 환경적 폐해와 경제적 손실이 심각하다는 것을 암시한다. 위와 같이 환경적, 경제적인 문제를 안고 있는 건설폐기물의 저감 및 재활용의 활성화를 위해서는 폐기물 발생부터 처리까지 포괄적으로 관리해야 할 필요성이 있다. 본 연구에서는 정보교환시스템과 폐기물전자인계서 제도가 각 건설현장마다 활성화 되어 폐기물관리가 효율적으로 이루어지기 위한 방안으로 이미 RFID기술이 적용된 사례분석을 통하여 무선 주파수 인식 기술(RFID)이 효율적으로 적용될 수 있는 방안을 제안 하는 것을 목적으로 한다.

건설폐기물의 발생량은 폐기물 발생량 중 큰 비중을 차지하고 있다. 또한 노후화된 건축물의 철거와 수많은 도시재개발 재건축 사업에 따라 건축물 해체 시 발생하는 건설폐기물은, 건설폐기물 발생량에 많은 영향을 주고 있다. 건설폐기물의 발생량 증가와 함께 처리방법에 대한 문제점들이 나타나고 있으며, 폐기물 처리와 관련한 환경문제들이 사회적 이슈로 논의되면서 건설폐기물의 처리와 그에 따르는 부차적인 문제점들이 중요한 과제로 대두되고 있다. 따라서 본 연구는 건축물 해체 시 발생하는 건설폐기물 처리의 문제점들을 분석하여 국내 건설폐기물 처리에 대한 개선방향을 제시하였다.

China is experiencing the urbanization at an unprecedented speed and scale in human history. The continuing growth of China's big cities, both in city land and population, has already led to great challenges in China's urban planning and construction activities, such as the continuous increase of construction and demolition (C&D) waste. Therefore, how to characterize cities' construction activities, particularly dynamically quantify the flows of building materials and construction debris, has become a pressing problem to alleviate the current shortage of resources and realize urban sustainable development. Accordingly, this study is designed to employ 4D-GIS (four dimensions-Geographic Information System) and Internet Plus to offer new approach for accurate but dynamic C&D waste management. The present study established a spatio-temporal pattern and material metabolism evolution model to characterize the geo-distribution of C&D waste by combing material flow analysis (MFA) and 4D-GIS. In addition, this study developed a mobile application (APP) for C&D waste trading and information management, which could be more effective for stakeholders to obtain useful information. Moreover, a cloud database was built in the APP to disclose the flows of C&D waste by the monitoring information from vehicles at regional level. To summarize, these findings could provide basic data and management methods for the supply and reverse supply of building materials. Meanwhile, the methodologies are practical to C&D waste management and beyond.

정부는 증가하는 건설폐기물의 발생량을 줄이고 재활용을 극대화하기 위해서 폐기물처분 분담금제도를 도입하였다. 이로 인해 폐기물 처리비가 상승할 수밖에 없어 발주처와 건설폐기물처리자간에 분쟁이 커지고 있으며, 건설폐기물 처리비의 현실화를 모두 주장하고 있다. 따라서 본 연구에서는 건설폐기물 관리의 문제점을 파악하고 개선점을 찾기 위해 현장조사를 실시하였다. 설문조사는 공공기관과 폐기물 관리업체 관련자를 대상으로 실시하고 건설폐기물의 업무, 제도, 처리비용, 처리방법 등으로 구분하여 분석하고, 그 결과를 제안하였다. 본 연구결과는 공공기관의 건설폐기물 지침규정과 폐기물처리 대가의 변경을 위한 기본 자료로 활용되었다.
