Scope of Work Building: SC-401 Project Title: Replacement of a 112.5 KVA PMT for Bldg. SC-401 Customer: Christopher J. Eyler, PE Scope By: Christopher J. Eyler, PE Date: 7/7/2015 Project Description: The scope of this project is to provide the replacement of the failed 15kV 112.5kVA, 11500 delta primary, 208Y/120 secondary Pad Mounted Transformer (PMT), in the SC Area at Naval Support Activity, Hampton Roads, Main Site, Norfolk, Virginia.

1. The contractor is responsible for the demolition and disposal of all projects' residual

materials like wires and transformers, etc.... 2. The contractor is responsible for submitting outage requests associated with the tasks

described in this SOW15 days in advance. 3. The contractor should provide all requirements in accordance with the specifications of

this SOW. The following lists are the tasks to perform in this scope of work: Electrical:

1. Demolish the failed 112.5kVA transformer. Retain the primary and secondary connection for connection to the secondary of the new.

2. Verify and mark the phase and rotation for all secondary cabling connection, prior to de-energize the temporary trailer mounted transformer. The contractor is required to check for proper phase and rotation upon completion of the transformer installation.

3. Remove existing transformer currently serving building SC-401 and properly dispose of the transformer.

4. Provide a new three-phase 112.5KVA Pad Mount Transformer (PMT), as specified, on the same foundation where the old transformer was located in order to reuse the existing primary and secondary cabling. The concrete pad may need modification to accommodate any differences between the failed building transformer and the new transformer. Remove and relocate the existing metering equipment for the building according to the location of the new PMT.

5. Connect the new 112.5 KVA PMT, using existing cabling. If existing cabling is not sufficient to provide proper termination to the new transformer, contact Chris Eyler at 757-341-1217 for government furnished cable.

6. Verify phase and rotation for all secondary cabling connection once the new 112.5 KVA PMT is energized.

Provide in accordance with NFPA 70.

3.16.1 Reconditioning of Surfaces

3.16.1.1 Unpaved Surfaces

Restore to their original elevation and condition unpaved surfaces disturbed during installation of duct . Preserve sod and topsoil removed during excavation and reinstall after backfilling is completed. Replace sod that is damaged by sod of quality equal to that removed. When the surface is disturbed in a newly seeded area, re-seed the restored surface with the same quantity and formula of seed as that used in the original seeding, and provide topsoiling, fertilizing, liming, seeding, sodding, sprigging, or mulching.

3.16.1.2 Paving Repairs

Where trenches, pits, or other excavations are made in existing roadways and other areas of pavement where surface treatment of any kind exists , restore such surface treatment or pavement the same thickness and in the same kind as previously existed, except as otherwise specified, and to match and tie into the adjacent and surrounding existing surfaces.


Provide concrete in accordance with this section .

3.17.1 Concrete Slabs for Equipment

Unless otherwise indicated, the slab must be at least 8 inches thick, reinforced with a 6 by 6 - W2.9 by W2.9 mesh, placed uniformly 4 inches from the top of the slab. Slab must be placed on a 6 inch thick, well-compacted gravel base. Top of concrete slab must be approximately 4 inches above finished grade with gradual slope for drainage. Edges above grade must have 1/2 inch chamfer. Slab must be of adequate size to project at least 8 inches beyond the equipment.

Stub up conduits, with bushings, 2 inches into cable wells in the concrete pad. Coordinate dimensions of cable wells with transformer cable training areas.

3.17.2 Sealing

When the installation is complete, seal all conduit and other entries into the equipment enclosure with an approved sealing compound. Seals must be of sufficient strength and durability to protect all energized live parts of the equipment from rodents, insects, or other foreign matter.

3.18 FIELD QUALITY CONTROL

3.18.1 Performance of Field Acceptance Checks and Tests

Perform in accordance with the manufacturer's recommendations, and include the following visual and mechanical inspections and electrical tests, performed in accordance with NETA ATS.



3.18.1.1 Medium Voltage Cables

Perform tests after installation of cable, splices, and terminators and before terminating to equipment or splicing to existing circuits.

a. Visual and Mechanical Inspection

(1) Inspect exposed cable sections for physical damage.

(2) Verify that cable is supplied and connected in accordance withcontract plans and specifications.

(3) Inspect for proper shield grounding, cable support, and cable termination.

(4) Verify that cable bends are not less than ICEA or manufacturer's minimum allowable bending radius.

(5) Inspect for proper fireproofing.

(6) Visually inspect jacket and insulation condition.

(7) Inspect for proper phase identification and arrangement.

b. Electrical Tests

(1) Perform a shield continuity test on each power cable by ohmmetermethod. Record ohmic value, resistance values in excess of 10 ohms per 1000 feet of cable must be investigated and justified.

(2) Perform acceptance test on new cables before the new cables are connected to existing cables and placed into service, including terminations and joints. Provide Insulation resitance testing of existing cable or where new cable assemblies connect to existing cable. Test the completed circuits with a 5000 volt megaohm tester. The reading should be 15 megaohms and climbing. If there is a problem reaching this level contact Chris Eyler at 341-1712. Test voltages must be as follows:

CABLE RATING AC TEST VOLTAGEfor ACCEPTANCE TESTING

5 kV 10kV rms(peak)

8 kV 13kV rms(peak)

15 kV 20kV rms(peak)



CABLE RATING AC TEST VOLTAGEfor MAINTENANCE TESTING

5 kV 7kV rms(peak)



CABLE RATING AC TEST VOLTAGEfor MAINTENANCE TESTING

8 kV 10kV rms(peak)




3.18.1.2 Low Voltage Cables, 600-Volt

Perform tests after installation of cable, splices and terminations and before terminating to equipment or splicing to existing circuits.

a. Visual and Mechanical Inspection

(1) Inspect exposed cable sections for physical damage.

(2) Verify that cable is supplied and connected in accordance withcontract plans and specifications.

(3) Verify tightness of accessible bolted electrical connections.

(4) Inspect compression-applied connectors for correct cable match and indentation.

(5) Visually inspect jacket and insulation condition.

(6) Inspect for proper phase identification and arrangement.

b. Electrical Tests

(1) Perform insulation resistance tests on wiring No. 6 AWG and largerdiameter using instrument which applies voltage of approximately 1000 volts dc for one minute.

(2) Perform continuity tests to insure correct cable connection.

3.18.1.3 Grounding System


Inspect ground system for compliance with contract plans and specifications

b. Electrical tests

Perform ground-impedance measurements utilizing the fall-of-potential method in accordance with IEEE 81. On systems consisting of interconnected ground rods, perform tests after interconnections are complete. On systems consisting of a single ground rod perform tests before any wire is connected. Take measurements in normally dry weather, not less than 48 hours after rainfall. Use a portable megohmmeter tester in accordance with manufacturer's instructions to test each ground or group of grounds. The instrument must be equipped with a meter reading directly in ohms or fractions thereof to indicate the ground value of the ground rod or grounding systems under test.




Upon completion of acceptance checks and tests, show by demonstration in service that circuits and devices are in good operating condition and properly performing the intended function. As an exception to requirements stated elsewhere in the contract, the Contracting Officer must be given 5 working days advance notice of the dates and times of checking and testing.
