Sustainable Group, Inc.

Scope Of Work

This project replaced and updated many components of the aviation fuel system at Air Station San Francisco that had reached the end of their useful service lives. Specific elements of work included the replacement of fuel transfer pump #1, replacement of two manual butterfly valves with automated vales, replacement of the leaking flex-bellow coupling and butterfly valve at the Tank #4 inlet piping, replacement of the malfunctioning ultrasonic level sensor at Tank #4, replacement of all indicator lamps, and the design/build of a new integrated system for continuous monitoring of volume/mass flowrates entering and leaving the buried aviation fuel piping at the fuel farm and the remote refueling stations. Sustainable Group personnel self-performed many of the construction activities involved in this extensive project to include all piping/valve improvements, and installation of the flow meters. On-site construction management, safety oversight, and Quality Control/Quality Assurance (QA/QC) services were also self-performed. In addition, this project was successfully completed at a very active Air Station with near continuous helicopter take offs and landings without any safety incidents of any kind.
