Waste Materials Management in Construction Industry in Khartoum State

Abstract

This research provides an overview of waste materials management in construction industry in Khartoum State – Republic of Sudan. Through the identification of the types of construction waste located in different construction sites and their causes and ways to minimize them. The purposes of this study are to give background information on construction waste problems in Khartoum and propose a practical guidance to building professionals on how to manage and minimise construction waste. Data collected using questionnaire administered on selected sub-contractors and project managers in Khartoum state. In the process, 103 completed questionnaires received at response rate of 100%, and used (SPSS) for analysing and processing data. The results indicate that the common waste materials been considered were steel with (51.5%), followed by Bricks, then come the Concrete, then wood and the less one was paper/bags. And notice that there’s some awareness among contractors of the practice of managing waste materials on site in Khartoum states, using four factors were specified as measures to minimise waste on site such as: reducing as the highest value, recycling, solid waste management and reusing product. Further developments are recommended to develop a scientific methodology to quantify construction waste. Furthermore, more practical support is required to enforce the implantation of Construction Waste management scheme in the construction and building field, It is also recommended to extend research on the area of recycling technique of building materials to induct feasibility studies, including cost and payback period analysis for each technique.
