Work began with an initial project scope for engineering and construction support of a 46-mile long, 40-inch diameter pipeline. A second 12-mile long, 36-inch diameter pipeline and a customary transfer-metering station were added two years later. These projects lasted four years with a total constructed value of $100 million.
The following five years of DOE work included 314 varied tasks associated with surface facilities for the underground storage caverns. The capital costs of the individual tasks varied between $100,000 and $60 million. Work on the DOE project included civil, control systems, electrical and piping disciplines. The contract required meeting ISO 9001 quality requirements.
In April 1994, Fluor recognized a significant safety milestone reaching one million safe workhours on the site, with 750,000 in the home office and 250,000 in the field.
