“Harnessing the Wind” Construction

The construction portfolio of “Harnessing the Wind” consists of 21 – 6 1/2” x 10” color digital photographs, printed on 8 1/2” x 11” Hahnemuhle Photo Rag Bright White 301 gsm smooth paper on an Epson 7890 printer using Epson’s Ultrachrome K3 inkset. I made five behind the scenes visits to document the construction of two utility grade commercial wind energy projects in the United States. The photographs were created between 2012 and 2014, printed by myself in Eureka, Nevada in November of 2015.

A large hole is excavated for the base of the wind turbine. Since this wind farm was built on Bureau of Land Management land, BLM archeologist contractors oversee the excavation watching for archeological artifacts. The painted diagram on the first layer of concrete is a template for the rebar. Pattern Energy’s Spring Valley Wind, Nevada.
