Existing Conditions (typical for each cooling tower) 1. There are (2) cooling towers on the roof of this facility. Each cooling tower has (2) fan motors housed on the exterior frame of each cooling tower. Each fan is powered with a two-speed 20 H, 480/3/60 fan motors. 2. The motors are fed from the motor control center in the basement. Each cooling tower has a dedicated two-speed motor starter. The remaining verbiage in this section pertains to a single cooling tower, and is typical for both: a. A single three-phase feed enters the motor starter and terminates at a 100-amp circuit breaker. b. From the line side of the breaker, the feed splits into two separate three-phase feeds, each going to a NEMA 3 size contactor, one designated as "low speed", and the other designated as "high speed". c. From the line side of each contactor, the three-phase feeds (two sets of three wires) run up to the roof. 3. Up at the roof, each three-phase feed to the fan motors hits a local disconnect, and the splits into two separate three-phase feeds. a. The "low speed" feeds terminate at the low speed legs of each motor. b. The "high speed" feeds terminate at the high speed legs of each motor. 4. Operation is such that, when the starter is commanded to operate on low speed (either manually or automatically via the control system), the "low speed" contactor is engaged, and both fan motors are energized to operate at low speed. Conversely, when the starter is commanded to operate on high speed, the "high speed" contactor is engaged, and both fan motors are energized to operate at high speed. B. Required Modifications (typical for each cooling tower) 1. Furnish and install two (2) new fan motors for each cooling tower (4 total) and a 20 HP VFD for each cooling tower fan motor (4 total) a. Furnish new motors for all cooling tower fans. Furnish a new 20HP 460/3/60 single speed motor rated for outdoor use (TE enclosure type), for each of the four cooling tower fans. b. Modify the motor starter control panels to eliminate starter functionality, such that the control panel serves only as a circuit breaker and disconnect switch. c. Disconnect the "low speed" feeds from the line side of the low speed contactor. These will not be re-used. Cap the conductors in a suitable manner. d. Up at the roof, intercept the three-phase "high speed" power wiring out to the motors. e. Furnish and install a VFD with three-contactor bypass for each motor (two fan motors per tower, thus two VFDs per tower). VFD manufacturer shall be ABB (to match the installed base of VFDs in the facility. f.S plit the "high speed" power wiring into two separate appropriately sized three-phase feeds, and terminate each three-phase feed to the line side of each VFD. g. Extend new three-phase feeds from the load side of ach VFD out to each motor, terminating at the "high speed" legs of the motors. h. Provide local disconnect service conforming to the National Electrical Code (NEC), either by re-using the existing disconnect or by providing new weather-tight disconnect switches. i. Provide installation wiring and rewiring of all the new cooling tower fan motors. 2. Required Control Wiring and Programming a. Run communication wiring, daisy-chaining the VFDs, and terminating at the JACE on the ninth floor. b. Program the control system to acknowledge the newly added equipment, and to operate the new equipment in accordance with the Sequence of Operation (fan speed control to maintain high-bound temperature setpoint of condenser water supply to chillers). c. Create graphics to reflect new equipment and control loops. Engage the end-user in the creation process. C. Test and Acceptance / Upgrade Installation Validation 1. Conduct start-up and operations of the VFDs, either by authorized factory personnel or by a qualified on-staff technician certified by the manufacturer to provide such service. 2. Confirm two-way communication between the BACS (connected JACE node) and the VFDs. 3. Send a manual command (through the control system) to run the VFDs through their entire speed/frequency range. Confirm proper operation and interoperability of the VFDs and the fan motors per the accepted sequence of operations (see current sequence at Attachment 4 ). 4. Implement the necessary control loops as required by the Sequence of Operation. Confirm the temperature control schemes as operable. 5. Upon the Contractor's completion of system installation, start-up and checkout, the government shall be informed in writing. The government shall select a representative to walk through the system. The Contractor will explain all of the system functions in detail and demonstrate system operation. Notation shall be made and the government and Contractor will address each issue until all are resolved to the satisfaction of the Government. At that point the training for the government on the operation of the system will be scheduled (see III.D.4 below). 6. Provide engineer control drawings (as-builts) of the upgraded system. 7 Document and date the validation process, for inclusion in the closeout documentation (see III.D.3 below). D. Work Quality Requirements, Assumptions and Constraints 1. The system will be installed by licensed electricians and trained mechanics in the direct employment of the electrical and temperature controls contractors. The controls contractor must be Tridium and Circon certified. 2. All conduit and piping will be installed in a neat and workman-like manner parallel or perpendicular to the building structure by a qualified electrician. 3. Fastening shall be secured to walls or ceilings by means of the appropriate screws, expansion screw anchors, toggle bolts, hollow wall screws, nylon expansion anchors or expansion shields. Plastic anchors referred to as "rawls" will not be accepted. 4. All wiring line and low voltage shall be protected in a metal raceway. 5. All VFD's and equipment shall be mounted on vibration free surfaces or a uni-strut frame. Multiple systems may be incorporated in a common enclosure. 6. No patching or painting is required. 7. Asbestos removal is not included in the scope of work. 8. All work must be conducted during normal working hours of the facility from 7:00 a.m. to 4:30 p.m. Monday through Friday except federal holidays. E. Project Completion & Closeout 1. Upon completion of installation, clean all work areas of debris, installation materials, etc. 2. Put the system into automatic operation, and verify proper operation. Verify control loops with an on-site visit one-two weeks after final validation. 3. Provide closeout documentation packages, to include the allowing as a minimum: a. VFD and fan motor operating and maintenance manuals; b. E ngineer control drawings (as-builts); c. Final Sequence of Operation & BACS Points List (current is at Attachment 3) ; d. Validation documentation (see III.C. above). 4. Provide 4 hours of end-user training. Training shall be a minimum of one 4-hour session. Upon training completion and acceptance/turnover document shall be generated, signed and distributed by both parties. F. Warranty - Include a one (1) year parts and labor warranty which will begin upon completion of the project and acceptance by the government. G. Pre-performance Submittals Prior to starting the project the contractor will provide the following submittals for pre-approval by the COTR before installation and programming begins: 1. A detailed description regarding new graphic displays. 2. Variable frequency drive assemblies and mounting locations. 3. Complete description of sequence of operations for cooling towers.
