  • 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.

  • Although waste management in construction industry has a significant impact on both economical and environmental issues, the current level of waste management performance in Korean construction is reported as relatively low. In this context, this study aimed to suggest the considerations for the improved construction waste management guideline, which leads to the effective waste management on a construction site. In order to reach this goal, the existing domestic construction waste management guidelines were analyzed based on the criteria of the environmental management procedure of ISO 14001. These considerations were described in three aspects such as "planning", "implementation and operation", and "checking and corrective actions".

  • 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.

  • Occurrence amount of construction waste dominates weight that is the most as 44.6% if examine domestic waste occurrence present condition, scales of construction becomes jumbo gradually depending on social environment that change and occurrence amount of construction waste is steadily increasing real condition. Construction waste processing and recycling expense have held about 0.5% to 1% of whole construction cost, but if do not manage construction waste efficiently in each construction site, ratio that construction waste processing and recycling expense hold in whole construction cost is expected that will rise more. This does hint that environmental harm and economical damage are serious by construction waste. In this study, system is activated in each construction site at information interchange system and waste electron succession and waste government official makes radio frequency realization technology (RFID) purpose suggest plan that can be applied efficiently through example analysis that a RFID technology is already applied by efficiently attained plan.

  • 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.

  • The government introduced a waste disposal share system to reduce the annual increase in construction waste and to increase the recycling rate. As a result, the cost of waste treatment by public institutions is growing inevitably, causing disagreements and disputes between the public owner and the construction waste treatment company. They are also arguing for an increase in construction waste disposal costs. Therefore, in this study, an on-site survey was conducted to identify the current construction waste management problems and to find improvements. The survey was conducted for supervisors of public institutions, construction companies, and those related to waste treatment companies. The survey results were analyzed by dividing the construction waste management, regulations, treatment cost, and treatment method. The results of this study were used as primary data for changes in the construction waste guidelines and waste treatment costs of public institutions.
