The second contract, awarded to ASI RCC, Inc, of Buena Vista, Colorado began on October 30, 2003, and is ongoing. Their work has consisted thus far of drilling grout holes from within the galleries and on the upstream face of the dam in preparation for chemical grouting the existing cracks in the dam. The work will also include installing stainless steel and asphalt as a flexible sealant in three cracks to provide a water stop in the structure. Several drain holes will also be drilled in the dam. Due to the extreme conditions during winter, the outside work will likely be shut down from December to February 2004, and is scheduled to take approximately one year.
