Description / Significance
The project included 6.6 miles of access roads, 16 turbine pads, and site development work for the wind farm substation.
The project included over 250,000 cubic yards of earth and rock to be excavated and processed to build access roads and crane path to the 40 turbine pads. Additionally, Sargent’s scope of work included storm water management , and erosion control.
One of the major challenges was Vermont’s very stringent erosion and sedimentation controls requirements.
The access roads on the ridge were constructed 25 feet wide to allow the crane to move from one tower pad to the next. When the turbines were complete, the roadway was narrowed to 16 feet by adding loam material along the sides to encourage natural re-vegetation.
