Aged housing,unlike remodeling projects has the requirement of having to demolish the existing structure before a building can be built. In the process, there is a large quantity of construction waste produced, which must be disposed of in an environment-friendly way. There have been increasing regulations for recycling of construction waste, managing the waste, and certification of building materials. Such regulations have called for toughening of the requirements in remodeling and demolition.
The studies that have been made on aged housing demolition have focused on productivity improvement in demolition. However, in order to satisfy the requirements of laws and regulations on demolition waste, a new method managing and handling the waste at the construction site.
In this respect,this study has focused on developing an environ ment-friendly remodeling demolition process model for ecological disposal of construction waste. This will reduce the schedule growth, cost overrun, and having to rework, which are the results of a lack of systematic demolition planning. It will enhance the structural stability and safety for the workers in the demolition work. Sorting the waste materials and recycling them will increase the rate of recycling and solve the problem of having to meet the current stringent waste management regulations, which is the purpose of this study. The followings are what the environment-friendly remodeling demolition process model calls for.
First, prior to actual demolition, a demolition drawing should be made to establish a work breakdown structure, which will set the scope of demolition and allow sorting out the waste materials. This will, in turn, enable the user to access accurate information on the disposal, landfill, and recycling and to gather information in advance work details.
Second, it defines the demolition activities and draws a diagram of the relationship between activities through the IDEF0 process model and allows systematic demolition work. The output data of the IDEF0 can be utilized in demolition and repairs and maintenance work, and remodeling.
Third, the process in which the waste is sorted and disposed of is included in the process model, and the waste materials can be sorted out and recycled that are produced in the demolition process. This will reduce the waste disposal costs and increase the rate of recycling of waste materials.
This study has used several case studies of housing and used a simulation in an environment-friendly remodeling demolition process model and quantitatively produced the effects of improvement. The value that is offered by the findings of the study is that the study uses an environment-friendly remodeling demolition process model, offering economyand safety and inducing environment-friendly project management for the ultimate purpose of environment-friendly remodel -ing.
If we restate the anticipated benefits that are suggested in the findings of the study, they would consist of primary (inside elements) and secondary (outside elements) benefits in improvement. The primary benefit is the improvement in the remodeling demolition management process and at the same time securing of safety and environment friendliness in demolition work. The secondary benefit is reduction of waste materials, reduction of waste disposal costs, mana -gement/supervision by the plan and drawing, inducement of enhancement of technology and improvement in technical expertise, improvement in technical and economic factors, and saving of resources and recycling, reduction of contaminants, complaints about safety and environment, improvement in the user's trust in the demolition process, and promotion of remodeling policy, and improve -ment in other social and industrial factors.
