| Remarks/Notes | Site information sources |
| No. of Stories above/below ground | 7/2 |
| Plan Shape | Elliptical |
| Base Dimensions | 320 x 230 ft |
| Typical Floor Dimensions | 274 x 186 ft |
| Design Date | 2010 |
| Instrumentation | 2014, 20 accelerometers on 6 levels and 4 relative displacement sensors in the building and 3 accelerometers at a reference free-field site. |
| Vertical Load Carrying System | Concrete fill over steel deck supported by steel beams and columns. The structure is supported on triple friction pendulum bearings. |
| Lateral Force Resisting System | Intermediate moment resisting steel frames at perimeter and interior locations at each level. Concrete shear walls at Basement 2 level. Isolation at the base using 115 triple friction pendulum bearings. |
| Foundation Type | 4' thick concrete mat foundation; mat is thickened to 6' at the elevator shaft. Concrete mat is sloped in some areas and has pedestals to support the bearings. |
| Remarks | Structural design is based on the 2007 California Building Code. Funding for instrumentation was provided by the owner as required by OSHPD. CSMIP provided assistance in instrumentation. |
