Construction waste – causes and solution: action research

The aim of this study was to identify the primary causes of construction waste and the most effective methods for reducing them. In the collaborative action research methodology, a questionnaire was used as a tool. Data from participants were analysed statistically using multiple regressions and descriptive statistics (percentage, mean and t-test). Responses were collected from various stakeholders from the construction industry having different expertise and work experience and spread across all of India. The primary causes of construction waste have been identified as being during material ordering, transit damage, negligent frame of mind of the working team, wrong work methodologies and improper work planning. Preparation of an appropriate waste management plan at the start and periodic review of the same by senior management; use of building certification methods; correct handing and return of leftover material from the site; a trained workforce at the site; and proper work methodologies are seen as being the most effective waste reduction techniques. Multiple regressions revealed that respondent work roles, experience and type of project were substantial positive factors that influence reducing waste management at the project site.
