This design-build opportunity arose from JBrennon's recommendation to EPB Chattanooga that a conceptual, design-build approach should be offered to select vendors for competition and construction of a new operations center in Chattanooga, TN. JBrennon and The Architecture Collaborative (TAC) of Knoxville, TN, teamed up with a variety of engineers, consultants, and subcontractors to propose upon the site development near Volkswagen Chattanooga. Though JBrennon was not selected, it was a finalist. The design-build proposal included the below details for our proposed, LEED Gold certified building and out parcel developments:
