The Russell City Energy Center is a 619-megawatt combined-cycle electric generating facility that services western Alameda County and the San Francisco Peninsula for the needs of 600,000 households. The Energy Center uses natural gas for fuel, allowing for a greater than 90% reduction of emissions and a 40% more fuel efficient than older, fossil-fueled generating facilities in the Bay Area. As part of the emission controls, the facility uses 100% reclaimed water from the City of  Hayward’s Water Pollution Control Facility for cooling and boiler makeup, preventing nearly four million gallons of wastewater per day from being discharged into the San Francisco Bay.

Signet provided special inspections, earthwork monitoring and materials testing services including geotechnical laboratory testing, soils/AC compaction testing and observation, asphalt, concrete placement, reinforced steel, offsite precast pile fabrication inspection, structural steel and non-destructive testing (UT/MT).
