Rogue’s Wind: Nicholson successfully completes micropile foundations for 8 wind turbines
Nicholson Construction has completed the design and installation of micropile foundations for eight wind turbine sites at the CPV Rogue’s Wind project in Patton, Pennsylvania (USA).
Each of the eight turbines are supported by 60 micropiles, arranged in two concentric rings of 30, spread over a 66-foot (20-meter) diameter foundation — for a total of 480 micropiles on the project.
All piles are 9-5/8 inches in diameter, with two design types tailored to site-specific subsurface conditions:
- Type A: Included a #10 top bar, a #18 drop bar, and 10 feet of bonded length into rock.
- Type B: Included a #10 top bar, a #24 drop bar, and 12 feet of bonded length.
- Type C: Included a #10 top bar, a #18 full length bar, and 10 feet of bonded length into rock.
Each micropile was fitted with top plates engineered to handle 311 kips (1,384 kN) in compression and 49 kips (218 kN) in tension.
Depending on the location, pile depths varied from approximately 53 to 165 feet (16 to 50 meters), for a total project length of approximately 59,000 linear feet (over 18,000 meters).
This project is another demonstration of Nicholson’s ability to deliver robust and high-performance foundation solutions in geotechnically demanding environments — all in support of the growing renewable energy sector.
