Optimization of Materials Wastage of Jordanian Construction Industry

The Jordanian construction industry is characterized by many challenges such as time and cost overruns, contractor’s lack of experience, and lack of skilled labors. This research aims to identify the major causes of materials wastage, determine the level of wastage for some selected materials in comparison with other 6 countries, and to develop strategies to manage and minimize wastage. The objectives of this research have been achieved through a survey of 61 questionnaires received by hand from contracting companies. The results of analyzing 49 factors contributing to materials wastage indicate that the main factors are as follows: design changes during construction phase, rework due to labor mistakes, purchases not complying with specifications, improper cutting of materials, and poor site layout​
