Genentech Hall, University of California, San Franciso, Mission Bay Campus. Genentech Hall is a new, structural steel framed building supported on concrete piles, the first structure of many to be built at Mission Bay. The governing code is CBC. The structural engineer is Rutherford & Chekene. This structure has six levels with metal deck concrete filled floors. Moment connections are seismic critical welded/bolted connections. Structural steel was fabricated by Gayle Mfg. Co. both Woodland, CA and Boise ID shops. The erector is Cal Erectors. Inspection requirements for concrete and structural steel were intense to comply with the strict requirements of the specifications. Up to five (5) welding inspectors were on site to provide the QA inspections for visual UT, MT, decking, bolting and stairways. |

Law Library, University of San Francisco
Seventy-foot deep-drilled piers secure the foundation of this four level steel-frame structure. Meanwhile, cover plates, HSB’s, S.C., and dog-bone beam reduction instill critical seismic fortification in the structure’s internal framework. The body of the building incorporates masonry, shotcrete, cast-in-place concrete, and metal deck fill. Finally, precast panels form the library’s exterior. In accordance with the San Francisco Building Code’s rigorous regulations on structural steel and welding, ISI performed continuous visual and ultrasonic (UT) testing during construction.

Developmental Biology and Genetics Building (19B) UCSF Mission Bay Campus
171,650 sf of laboratory and bioengineering space. This is a structural steel framed building on top of precast piles and concrete foundations. The building incorporated a special unbonded brace frame design fabricated in Japan to absorb seismic activity. 95% of full penetration welds were performed during shop fabrication so that field erection was a simple ;bolt-up operation. The shop fabrication at Herrick Corporation in Stockton, CA required 5 shop inspectors to keep up with the shop activity.
In addition to the structure, ISI also provided compaction testing and concrete placement inspection on the adjacent infrastructure and landscaping projects. 2002 - 2003

Human Genome Building, UC Lawrence Berkeley Laboratories
This building is a new structure on a hillside supported by drilled piers. It is a four-level steel framed structure with seismic welded moment connections. The engineer had to incorporate stringent welding quality control measures for this project as related to the Northridge Earthquake and its resultant findings on moment connections. Two full-time structural steel field inspectors were assigned for quality assurance inspections which included visual, UT, and MT inspections. Shop welding inspections were performed out-of-state. |

Loyola Village, Lone Mountain Campus, University of San Francisco
This is an apartment-style housing facility located at the foot of the USF Lone Mountain campus on the corner of Anza and Parker. Loyola Village consists of five buildings set around two courtyards and a pathway that leads to the center of USF Lone Mountain campus. The units range in size from studio floor plans to 3 bedroom, 3 bath layouts, some of which are town house buildings and some of which are apartment-style buildings. Loyola Village houses juniors, seniors, and graduate students, as well as faculty, staff, and their families |
