Reclamation awards contract for dam safety civil work

摘要

The U.S. Department of Interior's Bureau of Reclamation has awarded a US$45.7 million contract to Suulutaaq Inc. of Anchorage, Alaska, for dam safety civil construction work. This work includes an overlay of Mormon Island Auxiliary Dam to improve its seismic stability. Mormon Island Auxiliary Dam -part of the 198.72-MW Folsom Dam hydroelectric project on California's American River - is one of 12 structures containing Folsom Lake. The work is to include excavation of existing embankments, importing 450,000 cubic yards of processed filter and gravel drain material, placement of 1 million cubic yards of shell-based fill material from an existing stockpile, and excavation at the dam toe to install drain systems of pipe and filter.
