5.0 REQUIREMENTS:

5.1 Basic Services: The Contractor shall modify the T line in conformance to the specification in 5.2.

5.2 Task/Requirement:

5.2.1 The control cabinet for the T line containing a PLC and multiple I/O modules for the T line shall be relocated from directly behind tank T4 to a location directly behind tanks T6 and T7. This will require disconnection of signal and power wiring and reconnection of the wiring after the cabinet is relocated. The Contractor shall document this work with both wiring diagrams and ladder diagrams.

5.2.2 Tank T4 shall be converted from a rinse tank into a process tank containing an aqueous degreaser. This will require the fabrication and installation of a cover plate for the rinse overflow which cascades into the adjacent rinse tank (note: tanks T3 and T4 are countercurrent rinse tanks with incoming water flowing into T4, outgoing water from T4 flowing into T3, and outgoing water from T3 flowing to the rinsewater drain line). Tank T4 is constructed of 304 stainless steel so this cover plate shall also be fabricated from 304 stainless steel and welded into place.

5.2.3 Immersion heaters, heater controller, and branch fusing shall be installed on tank T4. The Government shall supply the heaters, heater controller, and branch fusing for installation. The Contractor shall provide any additional materials such as wiring to the controller and heaters in order to make this installation. All hardware required to properly mount the heaters, controller, and branch fusing shall be supplied by the Contractor. Immersion heater system shall be tied into the existing SCADA system and operating information viewable on the human machine interface (HMI).

5.2.4 Exhaust hood shall be installed on tank T4. The Government shall supply the exhaust hood for installation. The Contractor shall supply all hardware required for proper installation on tank T4.

5.2.5 Ducting between the T4 exhaust hood and the ventilation system shall be procured and installed by the Contractor. The ducting at tank T14 shall be disconnected by the Contractor, the stub at T14 shall be blanked off and the riser for the ducting at T14 which connects to the main ventilation line below the second-floor level shall be made ready for connection with ducting from T4. The ducting from T4 shall be routed from the exhaust hood to the second-floor level and then routed along the top of the grating for the second floor to the riser at T14. All ducting including 90-degree elbows and straight duct shall be 16 inch diameter and constructed from polyvinyl chloride (PVC) and shall be supplied by the Contractor.

5.2.6 The incoming rinse water line to T4 shall be relocated by the Contractor to T3; all materials and hardware necessary for this relocation shall be supplied by the Contractor.

5.2.7 A push air line shall be installed by the Contractor at the front of T4 and shall be of similar design as the push air lines in use by other process tanks in the T line. This line shall be connected by the Contractor to the existing push air system for the T line. All materials and hardware required for this push air line shall be supplied by the Contractor.

5.2.8 A pump constructed of chlorinated polyvinyl chloride (CPVC) shall be installed on T4 by the Contractor. This pump shall be supplied by the Government.

5.2.9 Tank T2 shall be converted from an alkaline cleaning bath to a phosphoric acid bath. This shall require the use of a PVC liner of minimum thickness of 1/8” and of dimensions at 72” long x 42” wide x 168” deep with a 4” flange. The Contractor shall procure and install this liner.

5.2.10 Rectification shall be installed for Tank T2 by the Contractor. The rectifier (asset M3499) shall be provided by the Government but shall be relocated by the Contractor from its current location on the first floor near Tank G5 to the new location on the first floor adjacent to Tank T7 on the former Chiller #3 pad. The Contractor shall make connection between the rectifier and tank bussing on Tank T2. The wiring for the positive polarity shall be coated with red insulation and the wiring for the negative polarity shall be coated with black insulation. The Contractor shall install this wiring using appropriate connection lugs between the wiring and the rectifier and between the wiring and the tank bussing. The 500 KCMIL wire with red and black insulation shall be supplied by the Government. The rectifier controller shall be relocated from Tank G5 to Tank T2 and tied into the T line SCADA system with the operating information viewable on the HMI.

5.2.11 Tank bussing for Tank T2 to hold 316 stainless steel cathodes shall be installed by the Contractor. The bus bars shall be of copper metal of sufficient thickness to support the weight of the cathodes (approximately 100 pounds) and to conduct up to 500 A of DC current and shall be supplied by the Government. The Contractor shall supply the proper number of supports for the cathode bussing to minimize deflection in the bus bars from the weight of the cathodes. The bus bars shall be electrically isolated from the stainless-steel tank and shall be connected to the positive polarity wiring supplied from the rectifier. Two conductive bronze saddles (rated for 500 A) for holding the anode bar shall be procured and installed by the Contractor. The anode bus bar shall be of copper metal and a diameter of 1” with a length of 80” and shall be supplied by the Government.

5.2.12 Two cathodes of 316 stainless steel and a thickness of 14 gauge shall be procured and installed on Tank T2 by the Contractor. These cathodes shall be of dimension 40” width and 110” length and shall be hung on each cathode bus bar using 316 stainless steel straps.

5.2.13 Tank T1 shall be converted from an aqueous degreasing bath to a phosphoric acid bath. This shall require the use of a PVC liner of minimum thickness of 1/8” and of dimensions at 72” long x 42” wide x 168” deep with a 4” flange. The Contractor shall procure and install this liner.

5.2.14 Rectification shall be installed for Tank T1 by the Contractor. The rectifier (asset M0014) shall be provided by the Government but shall be relocated by the Contractor from its current location on the first floor near Tank T14 to the new location on the first floor adjacent to Tank T1 on the east side of the T line. The Contractor shall make connection between the rectifier and tank bussing on Tank T1. The wiring for the positive polarity shall be coated with red insulation and the wiring for the negative polarity shall be coated with black insulation. The Contractor shall install this wiring using appropriate connection lugs between the wiring and the rectifier and between the wiring and the tank bussing. The 500 KCMIL wire with red and black insulation shall be supplied by the Government. The rectifier controller shall be relocated from Tank T14 to Tank T1 and tied into the T line SCADA system with the operating information viewable on the HMI.

5.2.15 Tank bussing for Tank T1 to hold 316 stainless steel cathodes shall be installed by the Contractor. The bus bars shall be of copper metal of sufficient thickness to support the weight of the cathodes (approximately 100 pounds) and to conduct up to 500 A of DC current and shall be supplied by the Government.
