Andi Bayu Putra, S.T., M.T., a faculty member of Civil Engineering at BINUS University, contributed to ICEED #9 on 27–28 August 2025 by presenting his research entitled “Analysis of Office Building Renovation Project Using the Housing Minister’s Regulation Method of 2016, 2022, and 2023.” His presentation examined a comparative analysis of renovation cost estimation methods based on the Housing Minister’s regulations across the three different years, highlighting how regulatory changes influence project budgeting and implementation efficiency. This study not only provides valuable insights into the evolution of construction cost standards in Indonesia but also offers practical recommendations for civil engineering professionals to adapt their planning and project management strategies in alignment with the most recent policies.
