ATTN: Mr. Chris Harder, P.E. FREESE•NICHOLS RE: Eagle Mountain Water Treatment Plant Expansion Project No. P164-060164052003 F&N No. FTW05340 PCM-0178, Assist Installation ofFWWD Procured Chiller #2 Dear Mr. Harder: Transmitted herewith please find a copy of Oscar Renda' s January 7, 2008 price proposal for the referenced extra work. The project was originally designed to change the original Phase I 80 ton chiller to a 100 ton chiller and to keep the original Phase Il 40 ton chiller. These chiller improvements would supply lhe appropriate HV AC equipment to support the Phase I, II, and ill facilities. After this project bid, the existing Phase II chiller had a partial failure which lost half of its cooling capacity; repair costs were so high that replacement was the most cost effective alternative. Initial negotiations with the contractor to modify the design to provide two 75 ton chillers through the construction contract were unsuccessful. It was then determined the most cost effective correction was to replace the original chiller with a new 50 ton chiller. The 10 ton increase in capacity allows for operation of critical cooling ( computer rooms and electrical rooms) should the large 100 ton chiller fail. Negotiations with the contractor to procure a replacement 50 ton chiller were unsuccessful. The FWWD -elected to bid the procurement of the 50 ton chiller through the Purchasing Department. Negotiations with the contractor continued for installation of the FWWD procured chiller and a cost of $30,012.00 was established. The FWWD elected not to have all of the installation work done by the Contractor and some of the work done by the plant electrical staff. The work performed by the Contractor included: • Remove old chiller • Install new underground piping and valves • Construct new chiller concrete slab • Provide hoisting assistance for setting new chiller • Install new connection piping, insulation, and instruments The cost of the Contractor's assistance work is$ 8,143.60 . . . ·~·-· '1" Mr . Chris Harder, P .E. EMWTP Ph 3 PCM..0178 January 8, 2008 Two other activities were performed under this PCM . The existing plant HV AC boilers 1 and 2 were found to need remotely controlled isolation valves to maintain proper boiler heating operations when only one boiler was required for heat load. The cost to install the valves, actuators, power, and controls is $8,566.27. Exhaust Fan 15 was replaced and specified to have a new 480V motor. The existing exhaust fan used 120V power. The most cost effective resolution was to replace the motor and associated pulleys and belt.

This expansion provides UW service from the new NS-IV HSPS pumps, extends the existing UW loop to circle the Phase III facility, and connects to the existing Phase I/II UW loop. As shown on sheet C-20 of the design drawings, the UW loop extension does not include installation of valves for isolation purposes. The addition of isolation valves is required to permit operational flexibility. The attached Figures C20-B and C20-C illustrate proposed /locations for installation of UW loop isolation valves as advised by FWWD. The valves shown include (2) 12" GA and (2) 8" GA. The four gate valves shall be furnished as resilient- seated type with non-rising stems (NRS) for direct bury (Section 02640). Installation shall be in accordance with Section 02640 and details shown on Sheet CZ-1 . \_,,,/ Figure C20-C also includes a modification to revise the three (3) branch lines at the north end of the Sedimentation Basins from a 2-1/2" to 3" diameter. The 3" diameter pipe is a common pipe size as opposed to the 2-1/2" diameter shown. Revise sheets MD-1 and MD-3 to reflect this modification also. In conjunction with the branch piping diameter revision, modify Detail BD /CZ-2 as shown in attached Figure CZl-A. Sheet ME-8 includes a vertical 4" UW-PVC line shown entering the chemical pipe trench towards the Chlorine / Ammonia Building. Sheet MF-4/Section 2 shows the continuation of the 4" UW-PVC line into the Chlorine/ Ammonia Building. Furn1sh and install a 4" BFV on each of these lines . The v alv es shall be as per Section 15100-2.16 .· -- UtilityWaler-lsoValves .doc Gay, Ted April 1, 2007 Page2 Sheet MC-5 shows a 4" UW-DI passing through Tunnel D and exiting the structure below grade towards the Lime Storage Area. This line is continued on Sheet ME-20. An isolation v alv e is required on this UW segment. Install a 4" resilient seated gate valve with NRS on the 4" UW PVC once it exits the main treatment structure. Installation shall be in accord an ce w ith Section 02640 and details shown on Sheet CZ-1. cc: Chris Harder (FWWD) Herman Franklin (FWWD) Gary Cook (FWWD) J.C.

During design, there were three areas of programming that could not be fully evaluated to determine the effort of Applications Engineering Services required. During negotiations with HSQ, the FWWD agreed to establish extra programming services for up to 160 hours at a rate of $130 per hour. The Contract did not fund these additional programming services. The three areas of programming effort have been completed in accordance with the Contract and 144 hours of effort were required. No additional programming effort is contemplated from the 160 hour original budget. The cost of the extra work is $20,829 .00. No change in Contract Time has been requested. We have reviewed this price proposal and are of the opinion that it is a fair and equitable price. We recommend the City accept this cost and issue a Change Order in the amount of $20,829.00 . Please advise if the Water Department desires this PCM be incorporated in a Change Order. Sincerely, FREESE AND NICHOLS, INC. :If~.~ /YU G. E . Gay, P.E .

Danny; Harder, Christopher Subject: Request from HSQ for Time and Materials effort to reprogram PLC 1 Ted- Du ri ng the latter part of the design phase it was observed that there were several items which would require investigation by HSQ before giving an estimate to implement. It was agreed that 160 hours would be kept in reserve in the HSQ contract to address these issues when there was an opportunity to investigate. HSQ would only be permitted to do the work upon submission of a time and materials (T&M) estimate and written confirmation hy the Engineer On consultation with the FWWD). These conditions are documented in the letter from Alan Nelson to Danny Shannon dated July 29 2005 (part of the contract documents) and in specification 13305 2.04 A through D . This is the first reque st from HSQ to utilize these reserve hours, and the estimate of up to 80 hours to modify the programming of the RSPS PLC 1 to meet the requirement of 13305 2.04 B . 3 regarding the RSPS programming is rea sonable. Modifications to PLC 1 as well as several existing Cimplicity scripts will be required an·d are included in the estimate , per telephone conversation between myself and Gary Waters today . Should less than 80 hours be needed , HSQ will only invoice for the amount actually used. It is recommended that the request be approved , subject to addressing any concerns the FWWD may have. Of the 3 areas requiring investigation by HSQ per 13305 2 .04 B , items 1 and 2 have already been completed w ithout request for additional compensation. The reason for this is because after investigation and consultation with FWWD by HSQ , the specific programming changes were made by FWWD personnel (Luke Matus). With respect to the current request, it is my opinion that it is less than what might have been expected because FWWD continues to be cooperat ive and has furnished HSQ with a loaner processor, chassis , and power supply so that the RSPS programming can be modified at HSQ and then tested in Fort Worth. It is my expectation that a second request for T&M hours for modification of the existing programming of the existing High Service Pump station will be made by HSQ once the RSPS programming is complete and tested . This is a lso identified in 13305 2 .04 B . 3 , but is separate from the RSPS effort . . This T&M level of 80 hours at $130 / hr conforms to the intent of the contract documents and does not represent a separate chang e order request. It therefore does not increase the amount of the contract allowance for HSQ . Please feel free to contact me if there are any questions .

This work will include: PLC programming, Cimplicity database changes and graphics modifications. We estimate the work wi ll take 60 Hrs and you will be billed at the previously agreed rate of $130 .00 per hour. To exped it e approval of this request we have attached the appropriate extract of the meeting minutes.: Wednesday August 30th 2006 ,. I Arrived at Eagle Mountain WTP to Host the second part of the Cimplicity Graphics Review. A copy of the sign-in sheet is atta ched . Minutes of the meeting: 1. High Service Pump Stations (HSPS) #1 and #2. HSQ confirmed that it is in the contract for HSQ to perform modification to the existing HSPS #1 and RWPS #1 controls . The following controls were discussed and confirmed. a . All pumps will be manual start/stop from Cimplicity . b. A review of pumps and their assigned distribution pipes was held. i. NS II : Existing Pumps 1,2 ,3,4 (Fixed Speed); 5 ,6 (VFD's); New Pumps 12 (Fixed Speed), 13, 14 (Future Fixed Speed). ii. NS Ill Existing pumps 7,8,9 , 10, 11 (Fixed Speed). iii. NS IV (Plant Utility Water): New Pumps 18 ,19 (VFD's) c . Pumps 5 and 6 Speed Controls : i. Pumps 5 and 6 will each be provided with an Auto/Manual switch on the Cimplicity popup pump control screen. The Auto/Manual will be interlocked in the PLC to ensure that only one pump can be in auto at a time. To change a pump from manual to auto it will be necessary to first switch the current auto pump to manual (it will maintain its current speed due to bump less transfer). Then the other pump can be switched to auto . ii. A flow deviation alarm will be generated if the Total NS II flow is not within plus/minus 2 MGD of the· operator entered Total NS II flow setpoint (Both the Total NS II flow and Deviation setpoints will be adjustable from Cimplicity). iii. The operators will enter a "Total NS II Flow Setpoint". iv. The Total NS II Flow will be calculated in PLC 7. This will involve transferring the HSPS #2 NSII flow (Loop 17020-01) from PLC 15 to PLC 7. Note: If communications fails the transferred HSPS #2 NSII flow in PLC 7 will "Hold last value". • Tota l NS II Flow = EM-HSPSNS2-FL + EM-HS2NS2-FL v. The Pumps 5 and 6 will modulate the speed via a flow PIO. The process variable will use EM-HSPSNS2-FL and the Setpoint for the PIO will be calculated in PLC by the following formulae . • HSPS #1 NSII Flow Spt = Total NS II Flow Spt -EM-HSPSNS2-FL d . Pumps 18 and 19 Speed Controls: i. These two pumps w ill have the same basic functions as described for Pumps 5 and 6 . However, the operator will enter a pressure control setpoint. The PIO will then adjust the speed of the pump to ma intain pumps 18 and 19 Discharge Header pressure (Loop 17050-01 ). ii. Loop 17050-01 will have a low pressure alarm of 40 PSI. e. The following minimum speed will be included . i. HSPS #1 pumps 5 and 6 will have the manual speed setpoint 11 /1 5/2007 --o----- clamped at a low of50% in Cimplicity. The PIO block inside the PLC will also be clamped at 50% adjustable from Cimplicity . Thanks , Gary Waters Support Engineer HSQ Techno logy, 26227 Research Road. Hayward, CA 94545 Te l.

During review of the computer controls submittal, it was found the sodium hydroxide recirculation pump did not have a suction side low pressure switch. Also, the suction and discharge pressure switch seals were modified to improve performance by utilizing annular seals to prevent problems with crystallization. Miscellaneous electrical controls modifications were made to accommodate this protective equipment. The cost of the extra work is $3,070.00. No change in Contract Time has been requested. We have reviewed this price proposal and are of the opinion that it is a fair and equitable price. We recommend the City accept this cost and issue a Change Order in the amount of $3 ,070.00.

Memorandum (Email) To: Ted Gay Freese & Nichols, Inc. From: Chad Bartruff COM Date: July 10, 2006 Subject: EMWTP Phase Ill Expansion Request for Information No. 39 (RFl-39) Loop 12720 -Sodium Hydroxide Recirculation Pump Based on the application engineering supplier's (HSQ) review of the loop drawings and electrical schematics associated with the Sodium Hydroxide Recirculation Pump, clarification is required to resolve discrepancies noted in RFI-39. Specifically, it was noted that electrical Schematic 1 / Sheet EE-40 does not have provision for a High Discharge Pressure Switch and Low-Low Storage Tank Level interlocks as shown in Loop 12720, Sheet 1-17. Shop drawing review comments were issued to clarify this discrepancy. As part of the response to SD-16480-0lA, a revised electrical schematic was issued for the recirculation pump (Figure 40-C). Applicable revisions were made to Schematic 1 / EE -40 and are illustrated in Figure 40-D. To provide further clarification the following is an operational description for Loop 12720 - Sodium Hydroxide Recirculation Pump as related to the revised pump schematic shown in Figure 40-C. 1 . Sodium Hydroxide recirculation pump (Loop 12720) will operate at all times to keep the storage tank contents mixed . 2. The recirculation pump will have protective devices consisting of a low suction pressure . switch and a high discharge pressure switch. Both switches will be protected from exposure to NaOH by using annular-style diaphragm seals. The low suction pressure switch will be a compound vacuum / pressure switch, the high discharge pressure will be a standard pressure switch. There will be no interlock using tank level as the equivalent pump protection will be accomplished using the compound pressure / vacuum switch. RFl-39 Loo p 12720 Gay, Ted July 10, 2006 Page2 · 3. The pump suction vacuum / pressure switch and associated pressure seal will be added to the PCSI scope of work. It will be clarified by submittal review that the pressure seals must be annular. 4. A Local -Off -Remote (LOR) switch and Start/ Lockout-Stop control station will be provided at the pump. A Hand-Off-Auto (HOA) selector switch will be provided at the MCC. When the LOR switch is in L, the pump is started locally. When the LOR switch is in 0, the pump is off. When the Lockout-Stop (LOS) mushroom button is depressed, the pump will be locked out of running under any condition until the mushroom head is raised. When the LOR switch is in R, control is passed to the MCC, subject to the LOS mushroom button condition. 5. At the MCC, it will be possible to operate the pump from the MCC panel, or pass control to PLC-12, again subject to the LOS mushroom button condition. When the HOA switch is in hand, the pump will run. When the HOA switch is in 0 , the pump will not run. When the HOA switch is in A, control is transferred to PLC-12. 6. Schematic Drawing 40-C has been issued to reflect this operating philosophy and includes other motor safety devices. Loop 12720 and 12700 will be updated and reissued at a later date to match drawing 40-C and the overall design intent. 7. At the HMI, whenever the HOA and LOR are in any other position other than A and R, the HMI will display that the pump is in "MAINTENANCE" mode. Related wiring modifications required for this revision are shown in the attached Figures 34-A and 43-A. Please feel free to contact me should you have other questions regarding this clarification. cc : Norma Bailes (FNI) Gary Waters (HSQ) John Robinson (COM) Madhukar Deshpande (GAi) File: GS 5.0 (RFI-039) Docume nt code CDNI H :i STOP-LO STOP .t. t;i 7 9 10 12 12r:NW:.

By: x!I. £. 7 ~ Date: October 10, 2007 2 CDM Memorandum To: Ted Gay FNI From: John Robinson/ Gary Chiang COM Date: October 9, 2007 Subject: Eagle Mountain WTP Phase 3 -Plant Improvements Traveling Screen Control Changes Background The Brackett-Green Traveling Screen installed under the Eagle Mountain Phase 3 project currently operates based on a differential level setting at the screens. Plant staff has requested that the controls be modified to permit manual, timed, or differential level initiation from the plant control system. Reference Proposed hardware changes for the traveling screen are based on the submitted and approved drawings D-JOS-307-300 (Control Panel Layout), D-JOS-307-301 (Control Schematic Sheet 1 of 2), D-JOS":'307-301 (Control Schematic Sheet 2 of 2) of submittal 11206-01. Proposed logic changes are based on the "Typical Operation-Differential" narrative contained in the referenced submittal. Proposed changes for the plant control system are based on approved shop drawings for PLC 11, and approved control logic submittals. H:\Construction\Memos & Letters\Traveling Screen Control mods .doc .. OveNiew The modifications are based on adding a parallel contact to the "DP High" input to the screen PLC, and providing feedback of the Hand-Off-Auto (HOA) selector switch when it is in" Auto". When the selector switch is in" Auto" the traveling screen will turn on if (a) the differential level contact of the ultrasonic transmitter is actuated (the current method) or (b) if an output contact from the plant control system is closed. An interposing relay will be added to separate the 120 volt outputs of the plant control system from the 24 volt control voltage of the traveling screen assembly. Status of the HOA switch (Auto or Local) will be displayed at the HMI. Traveling Screen Modifications A parallel contact to the "DP High'' input will be wired in the panel. An auxiliary contact will be added to the HOA selector switch to transmit positive indication of it being in the "Auto" position. The "DP High High" input will not be changed, and the existing logic in the traveling screen PLC will not be changed. (1) Provide a relay with a dry contact wired in parallel to the existing dry contact input for differential level The dry contact would be wired between terminals 6 and 7 of the input terminal 17 of the traveling water PLC. (2) The relay will be energized by a 120 volt discrete output signal from plant control system PLC 11. Provide suitable term.inal block assignments wired to the relay energizing terminals such that the discrete output from PLC 11 can be easily wired to the terminal blocks without the need to be wired directly to the relay. Label all components in the panel. (3) Provide an auxiliary contact on the existing panel HOA switch. The contact would be wired to a terminal strip in the panel and then from the panel to the plant control system PLC 11. The auxiliary contact will provide positive closure status when the HOA switch is in Auto position, and open status when in the Hand or Off position. (4) Coordinate and test operation of the relay and high differential level input to the screening PLC with the discrete output from PLC 11. (5) Coordinate and test operation of the HOA switch auxiliary contact with the discrete input to PLC 11. (6) Update final O&M drawings to show changes. H:\Construction\Memos & Letters\Traveling Screen Control mods .doc Page 2 of4 •• Plant Control System Modifications The modifications are based on adding programming to monitor auto status and permit control of the traveling screen "on'' duration from the plant control system. A discrete output and a discrete input will be added to PLC 11 and the signal wires will be routed from PLC 11 to the control panel at the traveling screen. Programming will be added to permit actuation based on an operator action, timer, or differential level. Loop 11060 logic will be updated. (1) New output. Assign a discrete output (DO) for control of the traveling screen motor in PLC 11. The output contact shall be closed when the plant control system commands the traveling screen to run and shall be open when the plant control system commands the screen to not run (maintained contact). (2) New input Assign a discrete input (DI) to monitor status of the HOA switch. The contact at the switch shall be closed when the switch is in the "Auto" position and will be open all other times. (3) Existing signals. Utilize the existing signals from the traveling screen (inlet level, outlet level, run status, overload, high differential alarm, and low wash pressure) in the updated programming logic. (4) Computer manual control: Provide a software selection for computer manual control Operator will have the ability to start or stop the traveling screen from an HMI screen. (5) Computer timer control: Provide a software selection for timed control of the screen One operator adjustable timer will be for the run duration and a second operator-adjustable timer will be for the non-running duration. Timers shall initially range from 1 minute to 300 minutes and shall be field adjusted at commissioning. (6) Computer differential level control. The computer differential level control is in addition to the differential level control at the screen itself. The differential level shall be calculated and indicated on the HMI. Operator adjustable start and stop setpoints shall be provided at the HMI. When the differential level exceeds the start setpoint for an adjustable time delay, the plant control system shall command the screen to run. When the differential level is less than the stop setpoint for an operator adjustable time delay, the plant control system shall command the screen to not run. (7) Display if the screen control panel HOA switch is in Auto. Interlock the Auto status to the output to prevent the output from being in the "energized" position unless the HOA switch is in Auto. Provide appropriate software and HMI configuration to prevent control of the screen from the plant control system unless the HOA switch is in Auto. H:\Construction\Memos & Letters\Traveling Screen Control mods .doc Page 3 of 4 .. , ·, Conductor installation New or spare conductors shall be utilized to transmit the HOA status and run command between the field and PLC 11. (1) Provide 4 #14 conductors from the screen panel to PLC 11, or utilize available spares. Route through spare conduit if there is no room in the conduit containing the existing signals. (2) Terminate the field end of the two DO conductors on the terminals assigned to the interposing relay installed in the traveling screen control panel. Terminate the panel end to the assigned DO output terminal in PLC 11. (3) Terminate the field end of the two DI conductors on the terminals assigned to the "Auto" status of the HOA selector switch installed in the traveling screen control panel Terminate the panel end to the assigned DI input terminal in PLCll. (4) Coordinate and test operation of the screen panel with PLC 11. H:\Construction\Memos & Letters\Traveling Screen Control mods .doc Page 4 of4 ( • .. I., C 1-.
