Schuff Steel - Pacific Division Tops Out Steel on the University of California San Francisco Institute for Regeneration Medicine
Fabricates and Installs First-of-Its-Kind Seismic Uplift Restraint Designed by Forell/Elsesser Engineers, Inc.

SAN FRANCISCO, CA--(Marketwire - October 28, 2009) - Schuff Steel, Pacific Division, a
subsidiary of Schuff International, Inc. (PINKSHEETS : SHFK ), a leading
family of steel companies providing fully integrated steel construction
services, has completed the majority of steel erection on the $123 million
University of California San Francisco Institute for Regeneration Medicine
located on the Parnassus Campus. Architect Rafael Viñoly designed the
institute, Smith Group is the design-build team architect and DPR
Construction, Inc. is the general contractor on the project.
"There is nothing typical about this building," said Steve Carroll, project
manager for Schuff Steel.
The institute is being constructed on a steep slope with an incline. The
site is extremely narrow and is wedged between a winding road and adjacent
buildings. The 46,283-square-foot facility is a series of four elevated
connected building pods that resemble inverted pyramids with terraced grass
roofs. Each of the four building pods step up nine feet higher than the
next as the facility climbs up the slope at a slight angle. When complete
the multi-level structure will be 65 feet wide by 600 feet long.
The main entrance to the institute is 90 feet above ground level and
accessed by a freestanding elevator outside of the facility. The building
can also be accessed by a 130-foot long by 90-foot high steel pedestrian
bridge currently under construction that connects the institute to the
ninth floor of the adjacent Health Science Building. The structure is
supported by HSS steel braces, beams and 20 steel columns that bear on
concrete piers.
To ensure maximum earthquake protection, Forell/Elsesser Engineers, Inc.,
the structural engineers on the project, fitted the institute with 42
Friction Pendulum seismic isolators that are located between the foundation
and the structure at every anchor of the building. Seismic isolators
dramatically reduce impact from seismic ground motion. They dissipate
earthquake energy and significantly reduce seismic distortions that would
otherwise force the building out of its original shape. Friction Pendulum
bearings will allow the structure to slide 26 inches in any horizontal
direction and two inches vertically to "filter" the earthquake's movement
and give the building a relatively gentle ride.
In addition to seismic isolators, Forell/Elsesser designed and collaborated
with Schuff to fabricate and install a first-of-its-kind independent uplift
restraint. Forell/Elsesser developed the uplift restraint to keep the
building from lifting during an earthquake. The uplift restraints are
positioned on the south side of the building where they will oppose the
20-foot cantilevers on the north side, which have no ground support. In
the event of an earthquake once the building starts to lift, the uplift
restraints will engage and hold the building down with up to 100 tons of
uplift force. A prototype was tested at the University of California San
Diego's Caltrans Seismic Response Modification Devices (SRMD) test
facility.
Schuff fabricated the eight uplift restraints to exceptionally demanding
tolerances at its Gilbert, Arizona steel plant. Each uplift restraint is
six feet square by three feet tall.
According to Mason Walters, S.E., principal at Forell/Elsesser Engineers,
"We examined a number of different options to make this facility as
earthquake resistant as possible. We developed the uplift restraint to
augment the seismic isolators where the building juts out. During an
earthquake, the uplift restraints are designed to move in the same
direction as the Friction Pendulum seismic isolators until the building
starts to lift at which point the uplift restraints act to hold the
structure down, while continuing to allow free horizontal movement."
To augment Forell/Elsesser's technical drawings and further demonstrate how
the uplift restraint would work, Walters actually built a model of the
device in his garage.
Working closely with the university, DPR Construction and Forell/Elsesser,
Schuff worked in a design-assist capacity to fabricate and plan steel
erection.
According to Steve Marusich, an associate at Forell/Elsesser Engineers, "Design-build was the
only way to cost effectively engineer, fabricate and erect this complex
facility. It allowed the entire design and construction team the ability
to arrive at creative solutions to construct the facility within budget
while meeting the rigorous demands of the design and site location."
The Institute for Regeneration Medicine is scheduled for completion in
mid-2010.
