A total of 72 completed questionnaire forms were analysed and the results shows that 8 of the 20 factors are highly important factors and fall in the red zone of the risk matrix. It was also observed that last minute client requirements is reported as most important factor in design related issues while “items not in compliance with specification” is the most risk factor in the category of the procurement. Besides these, “last minute client requirements” and “Mistakes in quantity surveys” are the key factors which have significant effect on project cost. The findings of this study will be helpful for the practitioner to improve design and procurement quality for controlling the waste generation.</p>
