AEC was contracted by a large general contractor to perform this design-build generator addition at Salem Health’s CEP Building in Salem, OR. Our scope of work involved the design and installation of shoring, installation of a 40,000 gallon underground fuel tank, piping, monitoring and controls. We began with the design of a soldier pile shoring system which required precise engineering, as the excavation area was directly adjacent to the building. The new 40,000 gallon fuel tank was approximately 70 feet in length and therefore required an excavation which was 76 feet long by 16 feet wide by 16 feet deep. Following the tank placement, crews poured a concrete slab 72 feet by 14 feet over the top of the underground storage tank (UST), and refinished all associated flooring with steel finish.
AEC also designed an all new fuel system to integrate with the old generator system so the two could be used in tandem or alternately. When the generators are powered on, they alternate via the sequence of operations, which automatically activates the tank which contains the greater amount of fuel, in order to keep the two working together properly.
We managed the installation of a master control panel in order to integrate between the old and new system. Crews piped in three new day tanks for the three new generators and installed the corresponding above ground and underground fuel piping. We then installed a fuel polishing filtration system, which was also integrated to polish either tank, and installed all new monitoring systems for old and new USTs.
