Langdon Wind Energy Center
This project involved the construction of 2 - 115kV substations for the Langdon Wind Energy Center which consists of 106 turbines and a 35 mile long transmission line. The work included excavation, concrete, structural steel supports, high voltage accessories, aluminum bus duct, breakers, switches, arrestor, transformers and ground grid. The deep cylinder concrete supports were placed with the use of caissons, drill augers and displacement pumps due to the high water table and poor soil conditions.
Sugar Hills Substation, East Grand Forks, Minnesota
Contract to Date - $1,018,110
Constructed a new 15,000 kVA, 69-12.47/7.2 kV substation to replace the existing water plant substation. The substation was built on marsh type soil with a high water table. The entire site had to be over-excavated three feet and suitable fill hauled in to accommodate construction. A relatively new slip forming method was used to pour 20’-35’ deep concrete piers. The concrete piers ranged from 2-4 feet in diameter and were placed concurrently with the displacement of the ground water.
“ICS’s professionalism and the skill and hard work of all those involved made for an enjoyable project that was completed on time and on budget. It was a pleasure working with you and hopefully, we can do it again.” Todd M. Forster, KBM
