|Thanks to a $55 million upgrade, the Veterans Affairs San Diego Healthcare System Building 1 can now withstand a 7.2 magnitude earthquake. The 920-day project concentrated on installing new foundations and exterior stair towers with integrated braced framing. Additional work focused on utility upgrades, core strengthening of the penthouse structure to the surrounding building, and beefing up particularly vulnerable areas, such as interior bridges, roof corners, and balconies.|
|Three decades after its original construction in the early 1970s, the Veterans Affairs San Diego Healthcare System Building 1 fell far short of current seismic codes. This not only put the building and its occupants—patients, doctors, nurses, visitors, and administrative staff—at risk in the event of a major earthquake, it violated a California state mandate requiring all hospitals to either retrofit or rebuild. In 2005, VA administrators opted to retrofit the six-story, 855,000-sf hospital—and remain open throughout the course of construction.
The Building Team, including general contractor Clark Construction Group, architect Leo A Daly, and structural engineer Nabih Youssef & Associates, worked out a five-phase plan for the $55 million project that would keep the hospital functioning throughout the scheduled 920-day project. Upon completion, the facility would be able to withstand a 7.2 magnitude earthquake.
