This research aims to improve the automation of formwork accessory planning of a BIM-based aluminum formwork layout planning system currently developed at the National Taiwan University for automating the layout planning of formwork panels. It has been proven to save engineers time in conducting formwork panel planning in several case studies. However, the engineers still need to spend a lot of time conducting formwork accessories planning manually in the system. Therefore, this research proposes an approach based on accessories planning rules to support automation for engineers in conducting prop generation, brace planning, waler planning, double waler planning, and quantity estimation of the accessories including waler bracket, pull tie, wedge, and pin. The case study result shows that the proposed approach can save engineers 87.5% of the time compared to the original process of conducting formwork accessory planning.falseAluminum Formwork Planning SystemBuilding Information ModelingFormwork AccessoriesPlanning Automation[SDGs]SDG11conference paper10.22260/ISARC2024/01232-s2.0-85199626404
