New North Atlanta High School
- 400,000 sq ft
- $75 million
- 11 stories
- Completed in 2013
- 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.
