Road construction for Kibby Mountain, Maine Turbines.
Scope of Work
Forty-four wind turbines on the boundary of mountains of Maine with roads and foundations. Foundations for these towers require MD&B to install 616 rock anchors.
Road construction for crane access requires recycling the terrain features to build a road that meets equipment parameters to haul materials on or off the mountain top. Between weather and rugged terrain, it takes extraordinary efforts to achieve the schedule to meet green power deadlines.
The team met the challenge by creating both the material needed and the grades required. Rock anchors for the foundations were designed with a larger diameter anchor than previously utilized. Testing these anchors to 679,000 lbs has proven the bond passes all PTI specifications.
This clearing of rock for access has been accomplished with a winter shutdown of only three months.
