Precast concrete has become an essential solution for supporting sustainable construction in Indonesia. This study aims to identify the key factors influencing precast concrete adoption in Indonesia. The research method involves a mixed-method approach consisting of an integrative literature review, followed by questionnaires to construction professionals. One hundred two valid responses were analyzed using Exploratory Factor Analysis. The study results indicate that seven groups of factors have a significant influence: integrated engineering and operational excellence, sustainable construction efficiency, risk-optimized construction, efficient construction ecosystem, lean construction practices, safety-driven precision, and energy-efficient and productive construction. Each of these groups is interrelated in influencing the decision and effectiveness of precast concrete implementation, focusing on construction efficiency, sustainability, and improving project quality. The findings suggest that adopting precast concrete can accelerate the construction process, reduce costs, and improve the safety and accuracy of work in the field. In addition, factors such as government policies and supporting markets are key to expanding the use of precast concrete in Indonesia. This study provides valuable insights for developing policies and strategies in introducing and expanding the use of precast concrete as an efficient and sustainable construction solution.
