Please note: This is a Sole Source Notification.. The DWR requires specialized maintenance on 12 of the 13 motors utilized by the Devils Lake Outlets for pumping operations. The maintenance will include either reconditioning (which includes standardized procedures such as motor dismantling, mechanical parts inspection, balancing, cleaning, bearing replacement, tolerance testing, insulation testing, and vibration testing) or rewinding (which includes reconditioning as well as restoring motor’s electrical function) depending on the existing motor conditions. Neither of these items will modify, improve, or alter motor capacity or function beyond its original condition and specifications. There are two different types of motors. The motors are either a 1250 HP vertical motor that are “GE Motors” or a 2000 HP vertical motor that are “US Motors”. The GE brand motors are approximately 8-feet tall, have a 3.5-foot diameter, and weigh approximately 11,000 pounds. The US brand motors are approximately 9.5-feet tall, have a 4-foot diameter, and weigh approximately 13,800 pounds. The DWR does not plan to conduct maintenance on all 12 motors in a single year due to the cost and limited maintenance window (this maintenance must be completed during the winter months when the Devils Lake Outlets are shut down; this window may be as short as 4 months); instead, motors will be scheduled on a rotating, 6-year schedule based on condition and operational priorities. Road restrictions in the spring must also be considered for timely reinstallation. As such, any prospective vendors must be located within North Dakota.
