Abstract

Now more Construction managers depends on scheduling tools based Critical Path Method (CPM) to can obtain total project duration plus activities’ float that leads to more efficiency for controlling and planning the studied construction projects. CPM was the best tool for construction projects time schedule but nowadays researchers were focused on drawbacks that loose its use as a decision making technique. This paper shows most of CPM drawbacks and discusses a modified tool for CPM model that is named Critical Path Segments (CPS). This CPS scheduling technique solves CPM drawbacks by three main ways: (1) Dividing duration of project activity into separated time segments; (2) All activities relationships were switched into sequential relation as finish to start and (3) Calculations and analysis were done by using forward path. Sample cases of studies were included to focus on CPM shortages and CPS detailed calculations and analysis were illustrated showing this CPS technique can handle the schedules by best way.
