CONSTRUCTION WASTE SOURCES, MANAGEMENT PLANNING AND PRACTICES: IN THE CASE OF 40/60 CONDUMINUM AND REAL ESTATES HOUSING IN ADDIS ABABA

Abstract

In Ethiopia construction industry significantly increase especially in Addis Ababa. In our capital city at this time there are huge construction projects (housing projects) because of this a huge construction material needs for construction process and In property usage of this material or other reasons there are a high amount of construction waste in the site so this waste polluted our environment on account of this waste must be change to use by waste management plan. Therefore, the purpose of this study was to know the source of construction waste and to select the best waste management plan from housing in (40/60 condominium sites and real estate). Establishing the contribution rates of different waste sources Establishing the contribution rates of different waste sources will enhance knowledge-based decision-making in developing appropriate strategy for mitigating construction waste. Quantitative research method, using survey questionnaire, was adopted in this study to assess the frequency and severity of contribution of the sources of waste. The result focused on the 8 source of construction waste and the variables were ranked based on the severity and frequency they contributed. As one of the findings of the study, Operation waste was identified as the highest contributor to construction waste. This study consequently demonstrated that waste has a significant contribution to the cost of construction. Finally, by using the research result possible recommendation was giving to minimize source of the construction waste. Clearly assign and communicate responsibilities: Ensure that those involved in the construction are aware of their responsibilities in relation to the waste management plan, be Clear about how the various element of the waste management plan will be implement and to ensure the plan is being implement.
