Nowadays, precast concrete structure system is one of the alternatives of construction methods that is mainly used in the construction projects. In its implementation, this method provides time and energy efficiencies and supports environment preservation. This method is also currently chosen as the main preference for bridge construction projects. However, along with the advantages that it provides, the construction works of precast concrete bridge is a complex project and should be planned and managed effectively. Also, full consideration of each aspect in the scope of this project, such as its defined methods, activities and resources in the construction works, which depend on the site and working condition, is essential. A standardized work breakdown structure (WBS) including the detailed WBS dictionary for its construction works for precast concrete bridge can provide in breaking down the abovementioned aspects and guide the constructor to execute the project. The WBS and its dictionary should be developed in the planning phase of the construction project. This paper explains the development of the WBS dictionary for the construction work of precast concrete bridge. The methodologies used are archive analysis, Delphi method and validated by experts. The WBS dictionary of the precast concrete bridge construction works consists of six (6) levels of WBS (including two supplementary levels), which itemize the work packages, work methods, activities, and resources.
