The construction industry revved up significantly in 2013, with the respondents to ENR California's annual survey of contractors reporting a 16.4% gain in revenue over the previous year.
Twin earth-pressure-balance tunnel-boring machines Mom Chung and Big Alma emerged into a water-filled retrieval pit in the heart of San Francisco in June, having raised the bar for cutting through variable soils without affecting existing infrastructure.
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.

"We have composite metal panels, insulated metal panels, plaster, curtain wall systems, precast panels and columns, and
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.

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.

The first massive gate for the Folsom Dam Auxiliary Spillway project arrived last month at Folsom, Calif.—about 20 miles east of Sacramento—after a four day, 600-mile journey. Carrying a bulkhead gate so large it took up two lanes of traffic to allow its passage, a 100-ft-long flatbed rolled onto the jobsite in the middle of the night on March 14 with a California Highway Patrol escort.

The six flat, panel-shaped bulkhead gates (below) are being
