Development of WBS (Work Breakdown Structure) Risk Based Standard for Planning Cost Estimation at Port Project

The planning of a Work Breakdown Structure project is inevitable, because WBS is the initial stage of project management that divides the activities into small work packages making it easy to manage.While the nature of a project is unique, it basically has elements of construction work that are relatively similar for the same project, so standardizing of the work is possible.The existence of standardization will speed up the project planning process and will reduce costs during the project planning period.This research has a goal of developing WBS standardization on port projects and identifies risks that may occur during project implementation and consider them in the cost estimation process.Risks are obtained from the perspective of the contractor as the project implementer.The study is limited to port construction projects.The data collected came from a questionnaire survey to experienced contractors on a port construction project.The results of this study are expected to help the contractor on the estimated costs to be able to know and anticipate the risks that may occur during the implementation of the port construction.
