The existing electrical service is a partly underground system beginning at the electric meter on wood panel next to the meter pole that then travels underground to a disconnect switch located on the exterior of the dam (see contract drawings), then travels through rigid metal conduit on the exterior of the dam and ends at the automatic transfer switch in the interior of the dam. The existing underground power service conductors have failed and have been bypassed with a temporary aerial service, while the remaining cables from the disconnect switch on the dam to the ATS have very low insulation resistance values. All the power conductors from the meter to the ATS shall be removed and disposed of and new power cable installed in the existing conduits. The underground conduit shall be replaced in its entirety, and the disconnect box at the end of dam shall be replaced with a new pull box. The contractor shall be required to remove the temporary power feed at the completion of the work, arrange for all required inspections, and arrange for the electric utility company, Penelec, to reconnect commercial power. The work also includes bituminous pavement removal, trenching and installation of underground conduit, trench backfilling and other incidental work.
