BnB Solutions launches BuilderHub Modeling Support, an automated rebar BIM modeling service for RC structures
Our joint venture partner BnB Solutions Co., Ltd. launched BuilderHub Modeling Support in July 2026 — a service that automatically generates BIM models including rebar from structural drawing data (DWG) for reinforced concrete structures. Built on BuilderHub-R, developed by ChangSoft Global, it addresses the two barriers that have held back BIM adoption: the effort of modeling work and the shortage of skilled staff.
