Utilizing BIM to improve the concrete reinforcement supply chain

Using Building Information Modeling (BIM) for design, detailing, fabrication and erection of concrete reinforcement and automating information exchange throughout AEC projects potentially improves productivity of the reinforcement supply chain. This study first develops an information flow process map documenting the reinforcement supply chain activities, and identifying the contents of the reinforcement models, created and exchanged by different disciplines during various phases of a concrete project. Then the identified information items are used as a basis to assess the functionality of BIM tools for reinforcement. BIM tools are evaluated in four areas: design and modeling, editing, project and construction management, and interoperability. The IFC schema is chosen as the preferred medium to examine the interoperability capabilities of the evaluated BIM tools. Our study identified significant enhancements in 3D parametric modeling and information interoperability of concrete reinforcement. Despite these improvements, notable modeling and interoperability deficiencies in the reviewed BIM tools remain unsolved. These shortcomings impact the modeling outcome and hinder effective use of BIM reinforcing models generated in design during fabrication and construction management. Recommendations to improve the identified shortcomings in all the four reviewed areas are provided.
