The drawing indicates that a 2-inch core drill hole is required through a wall, with four hydrophone cables to be routed through an empty conduit to the surface. The cables will be zip-tied to the conduit and run along the base/top of the wall, secured between a brick structure and railing. The distance of the overhead cable run is approximately 31 inches. Upon decommission, all holes will be filled with grout.
The related federal contract opportunity is for the LOCK 19 - UADS REPAIR and/or REMOVAL, issued as a Request for Quote (RFQ) by the U.S. Department of the Interior, U.S. Geological Survey.
