Here's a link to another committee, http://www.gcpci.org/index.cfm/technical/GDOT-PCI

'The GDOT-PCI Joint Committee is a committee made up of Georgia DOT (Bridge Design, Bridge Construction, Bridge Maintenance, Materials & Research)  and Georgia/Carolinas PCI Bridge Committee (transportation product precast/prestressed concrete fabricators). Meetings are often attended by representatives of FHWA GA District and state research university (Georgia Tech). The primary purpose of the Committee is to discuss DOT bridge related projects, concerns, details, research and industry solutions. The Committee typically meets twice a year'.
