Since 1969, Irby Construction Company has completed more than 4,000 miles of wood, steel, and concrete pole line construction of voltages from 69 kV to 500 kV. These lines have been built in a variety of climates, terrain, and environments from the snows of Alaska to the beaches of Florida, and from the island of Hawaii to the hills of West Virginia. These diverse locations and soil conditions have required a variety of types such as vibro-driven piling and augured concrete caissons. Whether the line is five miles or 125 miles in length, Irby crews exhibit the same quality workmanship and professionalism required to complete the project in a safe and timely manner and to the customer's satisfaction.
