A confidential power client wanted to assess the viability of constructing a hydropower pumped-storage facility that would pump water from a lake to an upper reservoir during off-peak periods and release it to generate power during peak demand. Barr was hired to evaluate the complex geologic stratigraphy of the proposed reservoirs, document anticipated foundation conditions for the proposed powerhouse, and monitor the presence and level of groundwater at the proposed reservoir and powerhouse locations. We provided geotechnical engineering and geological engineering services and subcontracted, supervised, and managed the drilling, testing, and geophysics work.
