Description
The U.S. Army Corps of Engineers, Alaska District, is conducting market research to determine the acquisition strategy for the Relief Well Pumping at the Chena Lakes Flood Control Project. The project involves providing all management, labor, equipment, travel, supplies, and materials to perform relief well pumping on up to 174 relief wells at the Chena River Lakes Flood Control Project, located approximately 18 miles east of Fairbanks, Alaska. The contractor must prepare and submit a Draft Work Plan, including a Quality Control Plan, Testing, Maintenance, and Monitoring Plan, and an Accident Prevention Plan. The contractor must also perform a step-drawdown test on all cleaned wells to determine their efficiency after cleaning.
Some key points to consider:
• The project requires the use of a submersible pump, motor, VFD, associated pipe, and pump assembly accessories to meet specific specifications.
• The contractor must provide a pump curve demonstrating the capability to deliver a minimum flow rate of 350 GPM at a head equivalent to the anticipated drawdown in the wells.
• The contractor must use a water level data logger and water level tape to track and monitor water levels during pumping tests.
• The contractor must use an electronic flow meter to measure the flow rate and a Rossum Sand Tester to determine the amount of sand in the effluent.
