Abstract: Minimising construction waste is a challenge for building construction industry. Very little study is carried out to audit construction waste. In absence which construction practitioners find it difficult to design most apt waste minimization & management tool. In this study, an attempt is made to develop a methodology to audit concrete waste from housing projects in India by deriving concrete waste indices. This paper is based on survey of 51 buildings from Maharashtra, India. 50 concrete waste generating factors (CWGF) were identified and grouped in five categories. Level of influence and factor weightages were identified from filed observations and questionnaire survey, and respondents’ rating on four point Likert scale was measured to find waste audit scores. This data is used to find Concrete Waste Index. Model was developed for auditing concrete waste. Model presented is easy to use for practitioners to find concrete waste on their sites. There is an established set of influencing factors which help them prepare best waste management system on site. Performance of concreting activity can be measured using this tool. Project owners can use it to measure loss in profit due to excess waste than standard. Results can be used by contractors and project managers to benchmark concrete waste and design waste minimization plan to have better control on concrete waste.
