Firstmark Foundations today announced it completed the construction of the Wind Speed II project which consisted of hundreds of concrete foundations that support a new, 126-mile overhead power line in Oklahoma.

Under a contract with Chapman Construction, 600 concrete foundations for a 345-kilovolt transmission line owned by Oklahoma Gas and Electric (OG&E) were constructed. Stretching 126 miles from Oklahoma City to Woodward, the project required 24,000 cubic yards of concrete and employed six drill crews and 75 professionals. The project is part of OG&E’s Windspeed II line from Woodward to its Cimarron substation, and is expected to be in service by mid-2018.

We were proud to partner with Chapman Construction and OG&E on this important project, which will help connect wind farms in Northwestern Oklahoma and alleviate congestion on the existing lines.
