Utah Construction Company

[1][2] The Wattis Brothers received funding from David Eccles, Thomas Dee,[2] Joseph Clark and James Pingree families.

Only four years after its founding, the company was awarded the contract to build the Feather River rail route, between Oakland and Salt Lake City, for the Western Pacific Railroad.

The Utah Construction Company subsequently thrived, and soon captured a large share of tunneling, grading, and track projects for the rapidly expanding railroads in the Mountain West.

In 1917, the Utah Construction Company was awarded the $7 million O'Shaughnessy Dam contract, a controversial project that impounded the Tuolumne River in the Hetch Hetchy Valley of California's Sierra Nevada mountains.

In 1931, the Wattis Brothers spearheaded the formation of Six Companies to build the Hoover Dam, which was the largest construction project ever tackled by the US Government up to that time.

Utah also filled in 400 acres (160 ha) of the San Francisco Bay to create much of the area of present-day south shore in Alameda.
