AUS was subcontracted by DGR grant Construction, Inc. to perform the diving portion of the 181B Wetwell Bulkhead replacement. Upon removing the trashracks, AUS divers discovered concrete overpour which had to be removed using a rock drill. The divers then cleaned and inspected the Wheelabrator Screen using a pressure washer. When the divers made it to the bulkhead, more overpour was discovered and removed. While AUS was installing the anchors, six of them hit rebar. Because of this, the divers had to burn 6 new holes in the bulkhead for the Anchors to rest.
