Hydroelectric projects such as the 3rd Unit Addition to Tulloch Dam in the Sierra foothills, electrical generation and distribution projects for NASA and the San Francisco International Airport, and bypass pipelines for Hetch Hetchy Water and Power, all highlight the expanding range of PrōVen's work in the power industry.
Tulloch Hydroelectric Project 3rd Unit Addition Phase 2 Construction
Work on the new third generating unit at Tulloch Lake and Dam in the Sierra foothills near Oakdale, California involved many facets of heavy construction. In order to install the new 6-megawatt generator, PrōVen crews had to remove over 15,000 CY of solid granite including an 80-foot deep shaft beneath the existing Tulloch Dam. Using both drill and shoot techniques and mechanical means, PrōVen's crews were able...
