| Abstract |
Construction delays and disruptions are common occurrence in most construction projects. These delays and disruptions can cause ripple effects as well as direct effects throughout the project. Serious consequences, therefore, may be occurred in those cases. it is hard, nevertheless to identify and prove accurately the consequences of ripple effects by such delays and disruptions. The system dynamic method can be used as a tool that can show the logical link between causes and effects; that is, delay, disruption, and productivity loss. This, in turn, helps in quantifying ripple effects because the system dynamics technique recognizes and models the interaction of work activities and the mechanism by which disruption occurs. Therefore, the results can be persuasive. This paper proposes an improved delay analysis method utilizing the hierarchical planning process and the system dynamics. A case study showed that the proposed method can be used as a tool to identify the ripple effects in analyzing the construction delay. |
