- DOCUMENT TITLE: Comment Response Matrix ENCORUS PROJECT NO. 21070 CLIENT PROJECT NO. 528A5-20-502 PROJECT DESCRIPTION: Design Boiler Replacement SUBMISSION: Pre-Bid RFI DATE: 6/13/2024 **Design Boiler Replacement - Canandaigua VAMC** # DWG/SPEC # Commenter Customer Comment Encorus Response VA Response Open/Closed 1 EI701 Per 23 09 11, paragraph 2.5 (Pg 37/69) there is one desktop computer and one, 19 monitor for the SCADA computer. However See updated 230911 paragraph 2.5 attached. See attached for 4160V Generator and CP-5 points list. Note that the CP-5 points list that contrains equipment that has been previously removed and would no longer need to be monitored. For the 480V switchgear, the SCADA system should monitor the status of each breaker within the switchgear and incoming and generator Voltage, Current, kW, kVA, PF, and kWH. The security system is stand alone, however provisions should be added to the operator stations to monitor cameras throughout and surrounding the boiler plant. The monitored points for the other equipment are shown on the PID Drawings 2 MK601 We do not see the receiver tank sizes in the mechanical schedule or specification. Could you please advise to the receiver tank size? We see the condensate receivers shown on drawing MK101 and see the pumps for this receiver on the MK601 schedule, but do not see any mention of tank size. A new condensate receriver schedule was provided with the previous set of RFI responses on 6/4/2024. The tank size is 65 gallons. The schedule is shown below. 3 In the RFI responses the Government lists two revised contract durations 730 and 750 calendar days. Can you please advise which number is correct? 750 Calendar Days 4 D-641 The drawing D-641 shows the blowdown separator cooling through a solenoid valve, which is controlled from panel...The drawing D-641 shows the blowdown separator cooling through a solenoid valve, which is controlled from panel CP-6A. CP-6A is the Deaerator control panel. Also shown is a temperature transmitter. 99% of the VA drawings show the self-controlling temperature regulating valve with capillary tubing. Please confirm the design intent is to have this process controlled via the PLC controlled solenoid valve for admitting cooling water to BDHR. Local control with capillary tubing is acceptable. 5 In review of D-621, 641, 642 can you please confirm that all the manual valves and other associated components for the main and pilot gas trains below will require position feedback (4-20mA) signal? Or is this a typo? The steam flow diagram D-642 has ZT position indication for all the manual valves (11 per my count) in the steam flow diagram. It s labeled as position feedback (4-20mA) signal, and not a simple switch contact (such as position either open or close limit switch). The steam silence vent valve(s) are manual. Typically, these are motorized electric modulating valves that can be controlled by master panel. This project does not appear to have this, but does have the position feedback of the manual vent valves as well. The safety relief valves are also indicating the requirements for a ZSO. We don t believe the illustrated valve exists. Please confirm if this is a typo and or specify manufacturer. The safety valves AFGSOV and APFGSOV are required to have a prove open switch, prove close switch, and a control open function. The vent valves AFGSVV and APFGSVV are required to have a prove open switch, prove close switch, and a control close function. The symbols above the pressure transmitters and flow transmitters are for the pressure and flow information, but the valves are just manual valves without any position indication or control. Manual valves on the steam header can have a close limit switch (ZIC). Although the drawing shows manual valves, a change to a motorized valve would be acceptable if desired for testing and tuning. The ZSO should not be on the safety relief valves. See specification 23 52 39 paragraph 2.2 B for requirements. 6 Drawing EI 111 details the dangerous gas detection system. Is there any technical information available for the existing system, IOM, wiring diagram, etc..? Yes, there are IOM manuals and reference drawings. One caveat is that the system was hacked up more than it was supposed to be by the company removing the biomass boilers. Reference documents are attached in case you want to post them. 7 Per the Specifications It is noted that only the Natural Gas piping system for the Mechanical and Plumbing scope is to be seismically rated. Can you confirm that this is the only required mechanical or plumbing system to require seismic bracing? Yes, the natural gas piping is the only seismically rated system. This document is also provided as an attachment.
