  7. Abstract:
  8. Wasteful approach in utilizing construction materials will result in depletion of resources and sacrificing future generations rights which is against sustainable development per se. As a corollary, presenting a new approach is aimed in this dissertation in order to decline avoidable building materials’ waste to the possible extent. This research focuses on wasted materials or construction waste. In this research, data about wastages of construction materials is gathered by surveying 32 residential buildings in Tehran. Afterwards, using multiple linear regression by IBM SPSS, wastages are quantified in terms of controllable independent variables namely floor area, number of stories, contract type and location. Other qualitative parameters are not studied. Then, a questionnaire survey is conducted to find the preferred construction waste reduction method according to construction industry experts’ opinions. Because the financial incentives were prioritized over fining policies by professionals, the researcher designed a financial incentive based program. In this proposed method, the reward was equal to demolition charge. This policy is proved to be both viable and environment friendly. Regarding the governmental budget required for this proposal, the researcher designed an advanced reward based program monetary requirements of which is satisfied via reduction of excessive purchase order as well as avoidable waste. To verify this program, a case study is done in Ardebil, Iran. The overall results of this dissertation indicate that, wastages of construction materials in residential buildings in Tehran can be quantified linearly. Furthermore, cement wastage is the most sensitive parameter to augmentation of financial rewards in construction sites. The consumption of raw materials and energies as well as emission of air pollutants in production of cement will dwindle significantly due to reduced demand of cement provided that the proposed financial reward program is implemented successfully by municipality of Tehran. In addition, a financial incentive based program which relies on reduction of purchased and wasted materials to supply needed budget, is proven to be applicable which acts in favor of reducing wastes and illegally dumped wastes besides improving recycling and reusing rates
