Atlanta, GA

  • $75 million
  • 11 stories
  • Completed in 2013

Structural Features

  • This project is the adaptive reuse of the old IBM campus to accommodate the new North Atlanta High School, serving 2,400 students.
  • New openings were required in the existing post tensioned beam floor system for new monumental and egress stairs. The capacity of the existing structure was increased through a combination of carbon fiber reinforced polymer reinforcing, widening of existing beams through the use of external post tensioning, and the installation of new steel wide flange beams.
  • Due to difficult excavation of partially weathered rock subgrade, the retaining wall in the gymnasium required an innovative and specialty design.
  • Due to sloping rock features, a hybrid deep foundation system was required to reduce unwanted differential settlement. To satisfy architectural requirements, a dual steel braced frame and concrete moment frame lateral system was employed.
