- Designed a new plaza waterproofing system
- Examined structural capacity of the Guastavino vaulting and verified geometry and load path in the field
Roof Restoration

- Preserved the decorative copper elements and bronze cheneau
- Installed skylights that were included in the original design
Foundation Repairs
