By any measure, San Francisco's effort to seismically upgrade its water supply is big. The $4.765-billion Water System Improvement Program (WSIP) includes 83 separate projects spread throughout the Bay Area and beyond.
In earthquake-prone San Francisco, crews are digging the city's deepest foundation piles for an 802-ft-tall office-residential tower that is on course to be the city's second-tallest structure, if only temporarily. The 55-story 181 Fremont tower, sited on land reclaimed from the San Francisco Bay after the 1906 earthquake, will be founded on 42 piers that plunge an average of 255 ft—with the deepest down 264 ft—to bedrock.

Fox snapped this photograph as part of a series he shot at the Anaheim Regional Transportation Intermodal Center (ARTIC) while workers installed the roof of the building. "I saw these riggers working against the framing of the structure and immediately saw an opportunity for a very graphic photo," says Fox, who is a principal and director of media services for SWA Group, the project's landscape architect.

Revenue from design work continues its modest upswing, according to an annual survey of top design firms conducted by ENR California and McGraw Hill Construction. The 109 participating firms collectively produced $3.66 billion of design work on projects located in California during 2013, an increase of 5% over the previous year. But design firms will face an increasing level of difficulty in finding the staff needed to meet the demands of California's infrastructure and water needs, say respondents.
