Client: US Air Force

Value: $3.4M


  • Removed and replaced six 10,000-gal STI above-ground fuel tanks

  • Project completed 6 weeks ahead of schedule

CMS executed a $3.4M design-build project to replace 6 identical horizontal, self-contained 10,000-gal STI aboveground fuel tanks and associated tank appurtenances servicing a vehicle fuel station. Work included existing tank removal and tank replacement with in-kind STI tanks per UL 2085 and all applicable STI, UFGS, NFPA, and UFC 3-460-1 requirements. All tank appurtenances, fittings, level, and overfill prevention equipment, inlet and outlet pipes, pipe supports, stairways, and platforms were removed and replaced. A new grounding system was installed, followed by commissioning. Throughout the project, the fueling station was never out of service for more than 3 hours.
