PART 1 GENERAL

SUMMARY OF WORK

1.1.1 Project Description

a. This Statement of Work (SOW) defines the effort required for removing & replacing Existing 300 kVA oil filled Transformer Bldg. 121. The oil in the unit will be evacuated by the Arsenal on the day of removal. Accordance to the nameplate, transformer has 200 GAL Liquid in its tank and total WT IS 5775LB. Disconnect the high and low sides of the existing transformer, along with any conduits physically attached. Disconnect 480V feeder from the existing transformer to the existing 480V Disconnect switch in according to the electrical drawing E102. Install a new 112.5 kVA Transformer (CU, 480∆ - 208 Y, dry type) inside building 121 and connect the primary and secondary feeder, utilizing existing fusible disconnects. Replace the 480V feeder from manhole (MH) 14 to the existing 480V disconnect switch according to the electrical drawing E102. Double tap this connection and supply 480V to a new fusible disconnect for the transformer primary. The transformer secondary shall have new conductors connected to a new fusible disconnect, then connected to the existing 225A load center. Test the secondary voltage and the phasing of a new transformer. Verify the grounding system and modify to meet NEC. The 300 kVA transformer and the existing fencing surrounding the transformer shall be removed from the Arsenal, by the contractor. The end result will be nothing on the existing pad, no fencing and no conduits protruding upward on the pad. All conduits will be capped or filled as to not leak.

1.1.2 Location of Work

a. The work is located at Bldg 121, approximately as indicated. The exact location will be shown by the Contracting Officer.

1.1.3 Period of Performance

a. The contractor shall be required to (i) commence work under this contract within 15 calendar days after the date the contractor receives notice to proceed, (ii) prosecute the work diligently, and (iii) complete the entire work ready for use not later than 60 calendar days after notice to proceed was given. The time stated for completion shall include final cleanup of the premises.

1.1.4 Hours of Operation

a. Normal duty hours are 7:00 AM through 4:00 PM, Monday through Thursday, and 7:00 AM through 3:00 PM on select Fridays (the arsenal is closed every-other Friday).
