STATEMENT OF WORK

FOR STEP-UP TRANFORMERS FOR NEWCOMPRESSED AIR SYSTEM

AT BLDG 351

DLA DISTRIBUTION WARNER ROBINS, GA

1. Background:

A. Requiring Organization: DLA Distribution Warner Robins, GA (DDWG), Building 351

B. History: Two Ingersoll Rand 30 horsepower (HP) air compressors systems were installed as part of the Box Shop in Bldg. 351 in Sep 24. The previous compressors were installed over 30 years ago and these new units are the replacements. The compressed air system supplies the air required to operate all wood working equipment within Bldg. 351. The existing two100 amp disconnects were labeled as 240 volt, 3 phase to power the two compressors. The problem encountered was that the disconnects were mislabeled and the old compressors were mislabeled because the building power disconnects were actually two 208 volt,100 amp, 3 phase. This is causing the compressors to trip the breakers during peak demand because incorrect voltage is being supplied. Also, over the long term, this problem could damage the compressors.

C. Scope of This New Contract: Supply and install two new 45kva Buck Boost or Equivalent Dry Type Step-Up Transformers (one for each compressor) (hook these to the existing 208 volt, 100 amp disconnects for each compressor on the primary side of the transformers then supply and install two 100 amp fused disconnect switches for the secondary side of the transformers. Then the contractor shall hook up the two new compressors to the secondary side of the transformers to convert the power from 208 volt to 230 volts, 3 phase power.

Specifications for the transformers are as follows:

Provide 2 each SQUARE D Co. Model Q-5421928 or equivalent transformers

· Designation: 45 KVA Buck Boost Transformer

· Transformer Type: DOE 2016 EX or EXN

· Transformer Rating: 45 kVA

· Transformer Phase: Three Phase

· Primary Voltage: 208V Delta

· Secondary Voltage: 240 V Delta

· Transformer Taps: 3 – 5% 1+2- Taps

· Transformer winding Material: Aluminum

· Sound Level: 39 DB

· Insulation & Temperature: Class 220 (H), 150 Dec C

· Enclosure Material: Standard painted ANSI 49 Grey

· Enclosure Type: Type 1

· UL Labeled

· Primary Lug Kits: DASKP250

· Secondary Lug Kits: DASKGS250

· 2- DASKP250-DASKP250 Lug Kit

· 2- DASKGS250-Mechanical Lug Kits

2. Equipment Supplied and Installed per the previous contract:

A. Compressors and dryers supplied were: 2 each Ingersoll Rand Rotary Screw Air Compressors, Model RS22I-A115-TAS-230, Horizontal, 30 HP 123 cfm, 120 gallon Tank, 230 V AC, 3 phase, 60 HZ with air dryer included.

B. Contractor supplied and installed two (2) each new compressed air supply systems (including air compressor, air dryers and filters) designed to provide compressed air to the box shop equipment in Bldg. 351. All equipment furnished was be designed and rated by the manufacturer for “continuous industrial use”. All required piping, valves, filters, separators, regulators, gauges, lubricators, and auxiliary components were provided by the contractor. The compressed air supply system shall include:

1) The compressors were designed to work such that each unit works on alternating days to ensure equal utilization. In addition, the second compressor was designed to activate in the event that the primary compressor for that day does not have sufficient capacity for the all the air requirements for the equipment at that particular time until the peak demand is satisfied. Salient characteristics of the compressors were as follows:

- Tank Style: horizontal

- Output Power: 30 HP

- Free Air Flow rate@ Maximum Pressure: 123 CFM

- Maximum Operating Pressure: 118 psi

- Tank size: 120 Gallon

- Phase: 3

- Input Voltage: 230 VAC

- Pump Type: Rotary Screw

- Number of Stages: 2

- Air Dryer included: Yes. (Per the requirements in paragraph 3)

- Oil Water Separator included

- Current rating: 97 A

- Frequency: 60 HZ

- Maximum Speed: 1775 RPM

- Duty Cycle: Continuous

- Sound level: 74 dBA

- Enclosure Type: Totally Enclosed

- Enclosure Rating: NEMA 4/IP 55

- Outlet size: 1 inch

- Outlet Type: NTP

- Outlet Gender: Female

- Overall Length: 75.4 in.

- Overall Height: 78 in.

- Overall Depth: 31.5 in.

- UNSPSC: 40151601

- Country of origin: USA

- Integrated Electrical control system

- 74 dBA per CAGI S5.1 standards

- Manufacturer’s Standard Color Paint

2) Two (2) each new refrigerated air dryers were supplied built into the air compressors meeting the following minimum specifications:

- pressure dew-point as low as 38°F with minimum pressure drop

- heavy duty industrial drain valve that does not require electricity, pre-setting, or manual intervention and discharges when condensate is present eliminating unnecessary loss of valuable compressed air

3. New Requirements to be provided under this contract:

A. All work and equipment shall comply with applicable requirements of OSHA, NEMA, NEC, NFPA, and ANSI codes and standards. Contractor shall also comply with all Federal and installation rules and guidelines while working on site.

B. Modification Required Under This Contract is to correct wrong voltage specified in the contract: Contractor shall supply and install two (2) 45KVA Step Up Boost Transformers (208 v to 230 v). The building disconnects were marked wrong. It said the disconnect was 100 amp 240 power source. Ingersol Rand discovered the power was marked wrong on the disconnect when they went to install the new compressors. The contractor shall supply and install the transformers and install two 100 amp fused disconnect switches for the secondary side of the transformers. The contractor shall also provide all necessary labor and electrical supplies to ensure a turnkey installation of the Step-Up Transformers in accordance with NEC so the correct voltage is supplied to the compressors. The building electrical power source for each compressor is 208 volt, 3 phase 100 amp power at the main disconnect for each compressor. All electrical installation of the step-up transformers and disconnects shall be provided in accordance with NEC to provide a turn-key fully operation systems. All material to install the step-up transformers and labor shall be provided under this contract. The original contractor shall be responsible for programming the compressors.

4. Deliverables: Upon completion of installation of the step-up transformers the contractor shall provide the following:

A. Documentation to include installation diagrams and maintenance manuals for the step-up transformers.

B. System warranties for the step-up transformers (minimum one year) on all equipment and installation from date of final acceptance by the Government.

5. Warranty:

Not withstanding inspection and acceptance by the Government or any provision of this contract concerning the conclusiveness thereof, the Contractor shall warrant the step-up transformers for a period of one year after final acceptance by the Government of the systems furnished and installed under this contract that the system will be free from defects in materials, workmanship, or requirements. During the warranty period and in the event the Contractor is not able to make remedial action his or herself; they shall make arrangements to have such work accomplished. The Contractor shall furnish to the Contracting Officer the name and address of the selected individual and/or firm who can arrive at DDWG with 24 hours after notification of equipment breakdown to perform the necessary repair.
