Our People are the best dam and reservoir specialists in the industry. Applying our expertise from design-assist and constructability review through roller-compacted concrete (RCC), conventional concrete or specialized earthfill placement, Barnard has earned its place among the top dam contractors in North America. Over four decades, we’ve worked on more than 80 dams, reservoirs, and dikes, from new construction to raising dams or conducting emergency repairs. We know dams so well that we were selected to decommission the Elwha and Glines Canyon dams on Washington’s Olympic Peninsula under the scrutiny of multiple federal agencies, a highly invested public and a heightened international media climate. Our work in dams during the last 20 years has included many projects focused on seismic rehabilitation. Our off-stream, above-ground reservoir construction has required slurry wall construction and geomembrane installation. We’ve worked in all types of terrain through all types of weather, even becoming adept at hurricane response in central New York. This work has been conducted under a wide range of contracts, including design-assist as a preferred tenderer for a public-private partnership’s future dam in a remote region of Queensland, Australia. Our teams stick with projects from “cradle-to-grave,” serving on a bid team and then heading into the field to construct the project they’ve bid. Value engineering is built into our project planning.
To tap a plentiful, renewable energy source for Newfoundland and Labrador, Nalcor Energy is harnessing the power of the lower Churchill River at Muskrat Falls. The North and South dams flank a new powerhouse and spillway.
The powerful Nelson River requires extensive site preparation and cofferdam and dyke construction, behind which the powerhouse can be constructed.
This project involves construction of a 9.2-mile-long, 30-foot-high earthen embankment to create a 3,500-acre reservoir.
Rehabilitating the north embankment of the Chilhowee Dam was critical to ensuring public safety and the continued use of the Chilhowee Dam and Hydroelectric Facility.
Following in the footsteps of their forefathers, residents of the City and Borough of Sitka voted nearly unanimously – 97 percent ‘Yes’ – to end their dependence on imported diesel fuel and raise their local Blue Lake Dam to produce more hydropower.
Barnard embarked on a Structural Modifications Program to help the TVA update six dams.
Ensuring that New York City’s 8.3 million residents, not to mention its daily workforce, have access to drinking water is a critical job.
Wedging a 1.5-mile-long, 208-foot-high RCC dam between an earthen dam and an active powerhouse on an expedited schedule resulted in the country’s largest ongoing dam construction project during all three years Barnard spent building the Saluda backup dam.
