California’s San Luis Obispo County has stopped work on a 45-mile-long pipeline and water-storage project after a third construction worker employed by Sacramento-based Teichert Construction died on a jobsite accident. The most recent fatality, near Pasa Robles, occurred on Aug. 20 when a vehicle backed up and struck Timothy Nelson, 29. Teichert is one of five prime contractors building segments of the pipeline for the county, which says the $176-million Nacimiento Pipeline is on budget and 85% complete. Last October, two Teichert employees at another Pasa Robles location drowned after being swept into a pipeline when a water line was accidentally ruptured. Teichert is appealing safety citations associated with those fatalities and says the firm “places the highest value on safety.”
