State Office Buildings 8 & 9

In the next month or two an eight year renovation project will be completed for State office buildings 8 & 9 which included 540,000 square feet of office space for the State of California Department of Social Services (DSS). These two 18 story towers had new mechanical, electrical and telecommunications systems, structural upgrades addressing seismic considerations, overall building upgrades meeting current code requirements, and minor repairs to the exterior shell. The seismic retrofit upgrades include epoxy dowel installation and hydraulic dampening system incorporated into the newly installed steel brace frames. Remaining renovations included the HVAC, electrical, plumbing, and fire/life systems.

The State of California, Department of General Services (DGS) relied on MatriScope to perform geotechnical engineering, micro pile installation, and perform special inspection and material testing related to cast-in-place concrete, epoxy anchors, masonry, structural steel, high-strength bolting, fireproofing and LEED Silver grade. A 12,000 SF addition will provide a secured lobby for the two buildings, a second-level walkway connecting OB8 and OB 9, and a child-care facility. Construction cost: $110 million.
