Under the direction of the supervisor and lead, perform journey-level pipefitting and steam fitting in support of the safe and continuous operations, maintenance, and repair of high energy thermal distribution utility systems including: High pressure steam (185 PSIG/380 Deg F), low pressure steam (10 PSIG/240 Deg F), and associated condensate return systems to provide heat to the campus; High pressure Campus Chilled Water (CCW) distribution system, providing cooling to the campus; High pressure compressed air distribution system that serves much of the campus’s building controls systems; UW Natural Gas Distribution System; and other campus utility piping systems at the University of Washington Seattle Campus. Troubleshoot, maintain, inspect, operate, and repair underground high energy thermal energy distribution systems, including pipelines, main service entrances/’headers’, meter-sets, pressure reducing stations or PRV’s, steam traps (F&T and Bucket), safety relief valves, isolation valves, condensate receivers and other related equipment and apparatus.
