Delay Analysis in EPC Projects using Ishikawa Diagram

Delay is one of the major issues in EPC projects in Oman. Project managers are not considering the root causes of delay while taking preventive measures. This project aims to identify the most common types of delay in EPC projects, to find out the root causes of delay by using Ishikawa diagram and further to prepare acceleration plan for a running project by using schedule compression techniques. The objectives of this project are: (a ) to identify root causes of various delays commonly affecting the EPC projects in Oman by using Ishikawa diagram. (b) to identify critical delay cause factors for a running project by conducting questionnaire survey. (c) to prepare acceleration plan for the project by using schedule compression techniques. To achieve this study: all the information was collected, schedules were compared to calculate the delay in each activity, questionnaire survey was conducted to study the impact of various factors causing delay and the root causes by using Ishikawa diagram and finally prepared an acceleration plan by using schedule compression techniques . The results found are: time and cost constraints are the biggest obstacle causing delay in EPC projects. The study identified the importance of analyzing the root causes before taking any particular preventive measures.
