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
