During the detailed inspections required lor the rupture disk installation, additional work wasidentified that needed to be addressed. This work was required to be completed at this time while Ihe equipment was open andthe equipment vendor was on-site,(2) This project variance Is largely due to the scope of work for the contractors increasing to include anti-vibration tube staking maten'aland labor and cathodic protection material and labor,(3) This project was included in the 2009 approved capital budget for $980,000. II was not included In the 2010 capital budget as thisproject was initially projected to be completed in 2009. The cost overrun is due to more oquipment/material required than originallyestimated, and the actual labor installation hours were higher than originally estimated. This projecl was a first-time "pilot' thatHECO undertook, to retrofit turbine water induction countermeasures onto generating units not originally designed with thesesystems. After detailed design, and during procurement, it was determined that Ihe retrofit equipment would not meet performancerequirements, necessitating changes that impacted material costs and installation labor.(4) Project credited with $1,26M insurance coverage because Ihis spare unit was used immediately to replace the failed Ewa Nui TsfA. Labor hours for assembling & testing the transformer as a spare unit under P0001518 was instead charged lo the Ewa Nui80MVA Tsf A Replace (P0002188) project.C;VDocumentsandSettings\jtakamur\LocalSettings\Temporarvlntemet Files\OLK2\20lOHECODraft PUCG0 7 Report031611.xls
