Cost Reduction for the Project Completion in Shortest Possible Duration by Stretching Noncritical Activities

The history records much about the worked construction miracle, but little about the methods of control. Critical Path Method (CPM) is one of the many network techniques which is widely used for planning, scheduling and controlling the projects. It assumes that the estimated completion time for a project can be shortened by applying additional resources: labor, equipment and capital to particular key activities. CPM can save money through better planning, and in construction, time is money. The main aim of this paper is a time-cost trade-off to find the shortest possible duration to complete project at least cost within available maximum budgeting. This is achieved by a method of stretching noncritical activities which at first crashing all activities simultaneously and then stretching noncritical activities to use up available slack and obtain the greatest cost savings.
