General Contractor achieves “award-winning” results with ArchiCAD

General Contractor, Atlanta-based, Holder Construction, showed architects and partners how to build faster and avoid costly change orders and field conflicts by developing a complete BIM model including structural and mechanical systems


Opening this month the Aquarium Hilton Garden Inn in Atlanta will be showcasing how Holder Construction utilized a complete BIM model for this award-winning $46 million project.

The architects and engineers in this case provided just 2D drawings of their designs, from which Holder Construction used to generate 3D architectural, structural and mechanical models in ArchiCAD.

Through frequent 3D coordination sessions, the project team was able to quickly identify and solve field conflicts, saving the project more than $800,000 in extras and change orders — avoiding months of delays. The non-BIM-savvy partners utilized the free NavisWorks model viewer to visualize Holder Construction’s BIM model.

“The relatively few architectural adjustments we have had to make on this project due to conflicts with MEP routing have alone been worth the BIM effort,” said David A. Deis, Senior Project Architect – Stevens & Wilkinson Stang & Newdow, Inc.

Serving as the BIM creator, integrator and manager, Holder modeled the structure, skin, MEP systems and interior finishes in ArchiCAD. The model was used by the owner, architect, preconstruction team and field team during all phases of the project. The ArchiCAD model seamlessly integrated with NavisWorks to enable the team to identify 590 collision conflicts.

Holder Construction won the 2007 Construction Best Information Technology Solutions (BITS) Award from theAssociate General Contractors of America for the most innovative use of technology to solve a particular business problem.
