Lake Oroville and Oroville Dam, located in Oroville, California, are part of a complex which includes Hyatt Powerplant, Thermalito Diversion Dam and Powerplant, the Feather River Fish Hatchery, Thermalito Power Canal, Thermalito Forebay, Thermalito Pumping- Generating Plant, and Thermalito Afterbay.
The Oroville- Thermalito Complex was designed as an efficient water and power system. It stores about 3.5 million acre-feet and generates power from releases made through Hyatt Powerplant and two other Thermalito generating plants.
At 770 ft. underground, Oroville Dam is the tallest dam in the nation.
We scanned 2 of the 6 power generator housing units and created a 3D model. Each generator has a 40 ft. diameter outer wall, with a 34 ft. diameter housing unit inside. We scanned the 6 ft. area between the wall and housing for the purpose of engineering a catwalk to be designed and manufactured off site and installed piece by piece on site. Accuracy was critical, as the catwalk was to be designed around the existing piping. This process using traditional methods would have been much less accurate and more time consuming, thus more costly.
