The New York City Dept. of Design and Construction (DDC) is the latest regional agency to issue building-information-modeling technology standards. The agency says the new guidelines establish a framework to enable all future DDC-managed public building design projects to be delivered using 3D design technologies and BIM processes. The guidelines require BIM on new projects valued between $15 million and $50 million, says Craig Chin, a DDC spokesman. BIM provides “a broad platform for collaboration across the project team,” says David Resnick, DDC deputy commissioner for public buildings. The agency joins a small list of others in the region, including the New York City Dept. of Buildings and the Dormitory Authority of the State of New York, that have BIM-based standards.
