PCI BIM Committee Presents the Benefits of openBIM

Interoperability refers to the ability of diverse systems and organizations who work together. That is exactly why the Precast Concrete Institute’s BIM Committee has teamed up with software developers: Nemetschek Vectorworks, Nemetschek Scia, StructureWorks and Tekla. Together they present a new integrated model based workflow, specialized for the needs of the precast industry.


This new integrated model based workflow holds the BIM Committee’s promises to streamline the design and production of precast structures. The effort was coordinated by Chuck Eastman, Professor and Director of the Georgia Tech Digital Building Laboratory, and Rafael Sacks at the Technion. Together they built their team.

The presentation at 2011 PCI Annual Convention and National Bridge Conference, illustrates the benefit of openBIM and how the Industry Foundation Classes (IFC) file exchange is allowing architects, engineers and precast manufactures using preferred software applications from multiple vendors, to leverage today’s BIM process to increase efficiencies, reduce errors and ultimately deliver higher preforming precast structures.

“The demo is just an initial stepping stone to deal with all the major exchanges facilitating precast workflows,” said Eastman.

This educational session demonstrated how a design model created by an architect using an IFC-capable BIM authoring application can be imported into a structural analysis software for optimization and code checking.

This optimized IFC model can then be moved downstream and converted into a detailed precast fabrication model. The parts and Bill of Materials of the fabrication model can be used as the inputs into the fabrication process and ultimately to manage the scheduling and project completion on the job site.

“We expect other companies aspiring to support precast work will be joining later,” said Eastman, Professor and Director of the Georgia Tech Digital Building Laboratory.

PCI, the Precast/Prestressed Concrete Institute (PCI) is the foremost developer of standards and methods for designing, fabricating, and constructing precast concrete structures. PCI develops, maintains and disseminates the industry’s body of knowledge and publishes a broad array of periodicals, technical manuals, reports, and other informational documents, including an award-winning technical journal.
