Digital transformation in the construction industry requires a workforce with competencies to address sustainability challenges, especially in coastal blue infrastructure projects. Building Information Modeling (BIM) has become an important technology because it can integrate hydrological, ecological, and construction analysis into one collaborative model, making it highly relevant for blue infrastructure planning.This study aims to analyze workforce competency needs in utilizing BIM for blue infrastructure planning and identify its role in supporting implementation. The research used a quantitative approach through surveys of construction professionals in Indonesia, supported by literature studies. The results show that BIM mastery is the digital skill most needed by the industry, but there is still a significant competency gap among workers. The main challenges include institutions not being ready to integrate BIM into the curriculum, economic limitations related to software licensing, and weak sustainability-oriented training curriculum design.This study recommends a roadmap for BIM integration into vocational education through curriculum reform, teacher capacity building, industry collaboration, and the development of national certification standards to accelerate digital transformation in the construction sector. The findings also emphasize the importance of interdisciplinary competencies such as environmental awareness, data analysis, and collaborative problem solving to support sustainable construction practices.
