Port Angeles City Light utility contacted Pacific Piling &
Underpinning (PPU) in May 1998 regarding a transformer at the city's largest substation.
The transformer base was settling, causing it to lean. The settlement created problems
in the connections at the top and breakage of one of the busses. The substation
had to be shut down. At the initial meeting the options discussed for leveling the
transformer included slabjacking, removing the transformer and replacing the base,
and piering. Slabjacking was ruled out due to weight considerations which were calculated
at 189,000 pounds. |
|
PPU proposed to install a test pier to verify the depth, capacity
and piering feasibility. The test pile was driven to 28 feet and considered by the
City Light engineer to be successful. PPU proposed one of the FASTEEL®
systems to the engineers after review by the engineers at FASTEEL®.
