As part of the Texas Facilities Commission (TFC) master plan, TFC wanted to consolidate its leased office space into state-owned buildings at the Capitol Complex and its North Austin Complex. At the latter location, the master plan called for a new 12-story, 420,000 sf office tower on a triangular site in the trendy, growing Triangle State neighborhood. An adjacent 7-level garage will accommodate 2,400 cars and will also house a chilled-water central utility plant that will support the new tower, with capacity to support planned future buildings. Ensight Haynes Whaley was selected as Engineer of Record and led the structural design of the desired 100-year life span development. The office building utilizes a conventionally reinforced concrete pan joist structural system with post-tensioned girders to provide the greatest flexibility and efficiency for the building floor plates. The team opted for a cast-in-place post-tensioned garage for efficiency and low life-cycle cost. The project required extensive coordination due to the amount of site work required to be completed while keeping all surrounding buildings operational.
