Development of Work Breakdown Structure (WBS) dictionary and checklist for safety planning on dam construction project

As one of the essential infrastructures needed for water resources, dam construction project requires comprehensive planning and effective standardization to accommodate the needs during the construction process. Also, the construction plan should be developed to minimize failures that can cause work accidents or other safety issues. Therefore, the development of WBS (Work Breakdown Structure) is a vital component in the planning process. In supporting these, a WBS dictionary and checklist are also needed to support the planning and control process of the project. Studies have found that these documents provide the details of deliverable, activity, and schedule information of each WBS components of the project. Also, these can be used for safety planning due to the hierarchy structure of each work package, hence making it easier for safety planning in each activities. This study was conducted by expert validation method through a semi-open questionnaire and analyzed using a descriptive statistical analysis method. The results of the study are the WBS dictionary and checklist for dam construction project, that can be the guideline for its safety planning. The study had also found the details of the construction method and resources for every work package in the dam construction project.
