To Develop an Intelligent Integrated Support System for Engineering Project (E-PMS): DECRIS and DLDs Analysis

Abstract

In order to manage engineering projects systematically and efficiently, the process of each project execution should be organically linked. The authors developed E-PMS (Engineering-Project Management System) for the linkage of processes. A tool called DECRIS (Detailed Engineering Completion Rating Index System) was developed to measure the completeness at the detailed design stage and to identify the starting point of construction (Steel Cutting). This helps the EPC contractor carry out the project by analysing the impact on schedules and costs during the engineering phase. Next is the DLDs Analysis. This study analysed the relationship between the results of the catch-up of the construction period and the delay liquidated damages (DLDs) based on limited resources and develops a model that can support the decision on whether to perform catch-up. The validity criterion of the model is that the results of the simulation of schedule shortening do not exceed the full DLDs incurred due to no catch-up plan. The result of the schedule catch-up simulation is the cost, which is the sum of the additional budget for a catch-up and the remaining DLDs. The reason for the validation criteria mentioned above is that the costs incurred for acceleration when excessive construction was performed to comply with the construction period can exceed the full DLDs.
