As prime contractor, North Wind was the primary firm for the construction of a Hazardous Category 2 nuclear facility used for the retrieval and excavation of radioactive and mixed wastes at the INL. The project involved the performance of multi-trade construction activities to complete the field erection of a retrieval enclosure (340 feet × 150 feet X 50 feet high), two snow canopies, and two passageways (30 feet × 135 feet and 20 feet x 94 feet). North Wind also performed the programming for the automated ventilation system tasked with maintaining negative pressure within the facility to ensure containment of the waste.
