Powerline Construction

Where the terrain on a project site is rough, a major road, rail or pipeline is encountered or an overhead power line route involves numerous angles we engage our partnered helicopter stringing operators to assist us with our stringing activity. This function is a cost-effective alternative to the traditional stringing methodology and requires the highly skilled pilot working together with our ground support to safely thread draw wire, conductor and cable into the stringing sheaves.
