Evaluation Planning and Scheduling of Repetitive Construction Projects in Iraq

The main goals of any successful construction project management system (s) are to complete the project on time, within the planned budget, and with the required quality limits. The three goals are inter-related where each of them is affecting, and being affected by, the others. In order to meet the time deadline of a project, an accurate scheduling should be sought. Due to the unique nature of construction projects, time contingency and project uncertainty are essential for accurate scheduling, which should be flexible enough to accommodate changes without negatively affecting the overall duration of the project Planning and scheduling is important in any construction project. Without proper that, many problems will occur such as extension of time or time overrun, exceeded the specified cost. Some of the researchers describe time and cost overrun as the most general problem in construction industry worldwide. Time overrun occur when the actual progress of a construction project is slower than the planned schedule. Cost or time overrun will affect all parties involved in the project. It will affect the profits which would be obtained if the project can be completed on the schedule. But due to that contractors had to spend more money on labor, plant and may lose the opportunity to get the next project. Hence, effective planning and scheduling management is very important and crucial to achieve successful completion of construction projects. Implementation in the best possible time depends primarily on the contractor experience and dash and motivate and financial position in contract. . This is accompanied by many different factors that affect with most contractors owing the limited expertise and limited management and rush to implement in the best time and cost, that depends on the contract state, planning, scheduling, control. Repetitive planning and scheduling methods are more effective than traditional critical path methods in the planning and scheduling of repetitive construction projects. Nevertheless, almost all the repetitive scheduling methods developed so far have been based on the premise that a repetitive project is comprised of many identical production units. In light of this requires the building conceptual model to planning and scheduling is a positive factor in all phases of the projects after studying the impact of various factors on that process for the most important party in projects ( contractor) and define standards.
