Replace Electrical Transformer at Building 520442

Federal Construction Group provided a new pad mounted transformer power supply to replace the existing indoor dry pack transformer.  We demolished and disposed of the primary loadbreak switch and dry type transformer, and replace the it with a pad mounted transformer located outside of the electric room.  Provided reinforced concrete pad sized for the pad mount transformer, provide the generator backup power for the duration of the outages required during the transition from the indoor transformer to the exterior pad mount.  Excavated, backfilled and compacted trench for the primary and secondary electrical duct with the undergournd duct being concrete encased.  Intercept ed underground primary duct and reutilize the duct for the primary and secondary from the pad mount transformer.  Provided concrete filled, painted, galvanized pipe bollards to protect transformer from vehicular traffic.  Privided primary cabling terminated at the power pole and in the pad mount transformer, provided secondary cabling from the pad mount transformer to the secondary distribution section, provide pull box (in electrical room) with conduit, connectors, channel, straps and hardware to extend the undergournd duct to the building secondary distribution section.  Provided grounding at the new pad mount transformer and reconfigure the ground in the building where the existing primary load break switch and dry pack trasformer were removed.  Tested for phase rotation, phase sequencing and voltage for the building electrical equipment and metering purposes.
