Waste resulting from construction operations affect the project, so that it adds
financial values of the project, without leading to any improvement in it,or to improve the
functional capabilities of the project, and lead to increased quantities re
quired, thereby
increasing the cost of the project and the accumulation of environmentally harmful solid
waste.
In this research, We will discuss the most important factors affecting the increase
waste in the Syrian construction projects by identifying the most important causess that
lead to an increase in waste materials, as well as identify the most important causes that
lead to increased waste associated with design, storage or supervision. These factors will
be arranged to determine the most effective on the project. At the end of the research we
will formulated mathematical model to Optimize cutting of reinforced steel bars and
Lindo program will be used to solve this model. It has been shown by the study that a
large proportion of waste is resulting from random cutting bars.
