The following items need to be addressed: V/1. The revision block on all sheets do not show revisions, yet we know some have been made. Please show revision callouts. �2. Sheet C-1, Plan View: Do you have the elevations at the four 90' bends just outside each meter vault? J3. Sheet C-1, East Profile: The 6"SS next to the inlet side of the east meter vault was relocated to the south. 4. 4. Sheet C-1, East and West Profile: During construction we discovered the meter piping was significantly lower than the water mains. Can you furnish the elevation of the meter vault piping and are the water main elevations accurate? 1 / 5. Sheets C-2 and C-3, Plan and Section: Cross out references to valve box shown next to hatch V slab. They were not installed. Also cross out keyed notes 19, 20, and 40 related to the valve box at these locations since they too were not used. �6. You mentioned to me on the phone earlier this month that the contractor put his changes on only one plan sheet and so only one plan sheet was marked up for "As -Built" purposes. SPU would like to have the changes reflected on all appropriate sheets so that confusion does not result from conflicting or misleading "as -built" information. With the above comments incorporated, I think we will have covered all the as -built issues of which we are aware.

We have gone through your comments and have revised the plans accordingly. Enclosed are two sets of revised plans for your review. We would like to advertise this project for bidding in March 2001 and start construction in April 2001. The following is our response to Jim Wilkes' review comments dated December 20, 2000. Sheet C-1, Plan View 1. East Service has a 6" SS crossing over the water line very close to the water meter vault. Replace this crossing with one length of ductile iron pipe, centered over the water line. Alternatively, can the east service be moved south to the vicinity of the driveway between "house No. 126 and No 150? See note: Existing 6" PVC SS to be replaced with 6" DI, on East Vault Plan View. It would be more complicated to move the vault between house no. 126 and house No. 150; there is an exit lane from Washington Mutual's drive through banking. 2. Please furnish stationingfor each bend. Stationing has been provided for each bend. 3. Two callouts for the proposed meter refer to SPUPlan#735-7. Since this plan has not been signed and changes may be made by the time it is adopted, we request that you delete reference to this unapproved standard plan on your drawings. Reference to SPU Plan #735-7 has been deleted. Sheet C-1, East & West Profiles 1. Reference to Sheet C-2 should be C-3. In East Profile detail reference has been changed to C-3. 2. The callout for Exist. Ground Elevation at Roadway Centerline should show the existing ground over the waterline, whether in the street or in the sidewalk 1055 South Grady Way - Renton, Washington 98055 �te�� ® 0 % This paper contains 5recycled material, 20"/ post consumer Page 2 March 8, 2001 New callouts are referencing Existing Sidewalk and Existing Driveway elevations. 3. Provide a minimum of two courses of brick and mortar under ring and covers for adjustability. The current design allows 40.2-foot (+2.5 inches) in which to place the --O-inch high ring and cover (and excluding brick and mortar). The higher sidewalk elevation will help, but sufficient depth of cover should be checked. Sufficient space provided under ring and covers for adjustability, minimum 2 courses of brick and mortar required. 4. The connections between proposed piping and existing water mains are shown as flanges which does not agree with other details and sheets in this plan set. The proposed 12-inch and 10-inch piping through the vault is shown as the same diameter as the existing 14-inch DIP water main. Graphical interpretation of pipes and connections are changed to reflect correct sizes and connections for the new water main. Including reducer and MJ connections. S. Please call out the connection stations. All four stationing points are shown on both Profile details. Sheet C-1 East Vault & West Vault 1. Please identify the union point between SPUand customer piping. Union points are shown and stationed on both Plan Views. 2. Please call out the stationing of the bends. Stationing of all bends are shown on both Plan Views. 3. The reference to Sheet C-2 in the East Vault detail should be C-3. Reference to Sheet C-2 has been changed to C-3 in the East Vault detail. 4. Please show the dimension between the existing water main centerline and the proposed meter centerline. Dimensions are shown: 10.93' on East Vault detail and 8.08' on West Vault detail. 5.

The calculations for Shackle rods appear to be inconsistent with the features of this project. Specifically: A. The last review comments specified that SPU normally uses both 3/-inch and 1-inch diameter shackle rods made ofASTMA36 steel round bars, which is fusion bonded epoxy coated. SPUdoes not use ASTMA242 heat -treated. High strength Cor-Ten steel in shackle rods. R SPU does not allow all -thread rod for use in shackle rods. C The design for shackle rods need to be compatible with the standard materials SPU uses in order that any future work or modifications will not be under -designed. D. Drawing conflict: Shackle rod coating on material lists for both meters is called out as fusion bonded epoxy (which is acceptable to SPZ9 but this sheet calls for hot -dipped galvanized without fusion bonded epoxy coating ( which is not acceptable to SPU) The shackle rodding design has been changed; a. Using 4 each of the 3/a"-diameter rod for 10"-diameter pipe, and 4 each 1 "-diameter rod for 14"-diameter pipe. Shackle rods are made of ASTM A36 steel round bars, which is fusion - bonded epoxy coated. b. The rod ends only have 6-inch of thread cut on each end. c. The design is compatible with the standard materials SPU uses. d. Drawing conflict has been corrected. Please see detail 2 of sheet C-4 and Special Provisions section: 7-11.3(6)E. 2. Renton standard method for sizing concrete thrust block is noted, but a thrust block design specific to this project could not be found. Concrete thrust block sizing has been updated. Required minimum bearing area against undisturbed soil is 33 square feet. Please see detail 1 of sheet C-4. H:\DIVISION.S\U"rl LITIE.S\DOCS\200I \2001- 120.doc\LC\tb Page 7 March 8, 2001 3. Star National Products claims that their SST 747 Tie Bolts are suitable for use with 1-inch shackle rods. SST 747 Tie Bolts are used. 4. The inclusion of the SPU Type 361 Ring and Cover details may not be needed now since review by other SPU staff has requested these large meter vaults to befitted with larger ring and covers as mentioned previously. The personnel access opening frame and cover is manufactured by Utility Vault Co. UV#3620-H2O, w/4" riser and cam type locking device. 5. Delete the City of Seattle seal just above the title block City of Seattle seal has been deleted. Corrosion Protection / Comments, All Sheets 1. Are Boeing's water mains Cathodically Protected (CP)? Coated? The specific water main has sacrificial anode protection only and no impressed current going through. The pipes are not poly -wrapped. 2. New meter piping shall be coated with coating consistent with SPU corrosion control recommendations. New water mains are coated w/100% solids polyurethane (Madison Chemical). Please see Corrosion Protection Notes #6 and #7 on sheet C-2 and C-3. 3. If Boeing water mains are cathodically protected, does Boeing want meter piping bonded into existing (Boeing) CP system? No. 4. If water mains are to be bonded into existing Boeing System. Omit Keyed Note Item #32, Insulating Flange Kit. Water mains are not to be bonded into existing Boeing system. 5. Put note on drawing to: Contact Jeff Pimentel (206-684-5913) to inspect and test joint bonding, and insulating flange kits. See Corrosion Protection Notes note#9 on sheet C-2 and C-3. HADI VISION.S\UTI LITI E.S\DOCS\200I \2001-120.doc\LC\tb Page 8 March 8, 2001 6. Magnesium Anodes maybe required if SPU meter piping is bonded to Boeing's existing system. Magnesium anodes are installed on the south and north side of water meters. Please see keyed note #36 on sheet C-2 / C-3. And Special Provisions section 8-23.1(D). 7. Please have Boeing Plant Engineer contact Jeff Pimentel to discuss item I through 6 above.

City of Renton Planning/Building/Public Works Department 1055 South Grady Way Renton, WA 98055 Subject: Relocation of Water Meters for Boeing Plant in Renton Thank you for the opportunity to review plans and specifications submitted March 8, 2001 for the subject project. Please accept the following comments from Seattle Public Utilities (SPU) for incorporation in this project. 1. Sheets C-1, C-2, and C-3 show a very tight clearance of about 6 inches between the top of the vault and the sidewalk surface. This will probably not allow enough cleance for the two courses of brick and mortar plus the ring and cover casting height. 2. Sheet C-1 profiles show stations at the connection pints that appear to relate to the bend locations in the plan view. 3. Sheet C-1 East and West Vault views show an "(MJ X MJ)" 90° bend following the union point. Please revise to show a (FL x MJ) bend as shown on sheets C-2 and C-3. 4. Sheet C-1 East Vault calls out "See Sheet C-3" in approximately the center of the view, but the correct sheet for this detail is probably C-2. S. Sheets C-2 and C-3 need to show an MJ x FL Adapter (SPU calls this a "hub and flange") at the union point, downstream of the 10 x 14 Increaser. This hub and flange shall be restrained to the increaser. Do not restrain across the flanged union point. 6. The valve box and valve operating nut extension shown on sheets C-2 and C-3 in the section views will likely not fit there. It will be OK to delete these. 7. Sheets C-2 and C-3 plan views show a close proximity between the rectangular and circular openings. The ring and covers and hatch slabs do not appear to have been drawn to scale in the section view. Please verify that the hatch slab and ring and covers may be centered properly over their respective openings without interference. Additionally, there does not appear to be enough room to place the hatch slab over the opening and behind the curbs in both meter locations. 8, In Note 4, on sheets C-2 and C-3, please change Keyed Note 3 to Keyed Note 9 9. On sheet C-4 the design pressures for thrust blocking and shackle rod designs are shown as 200/275 psi. I spoke with you and your staff about SPU's standard policy of using 300 psi for pressure testing. However, SPU does not normally test water services. Therfore, your present design is adequate and no change needs to be made. 10. Following closely on item 9. above, no pressure test of either meter assembly will be required by SPU. The meters are usually the most sensitive instrument in these installations and may be damaged by normal testing. Very important: To avoid holding up this review, contact SPU later to find out if SPU wants to make the final connection to the existing watermain on the SPU-side of the meter, or whether SPU wants to observe the Contractor performing this work. This item must be addressed with enough time left to schedule crews as necessary.

On sheets C-2 and C-3 remove the electrical bonding wire across the insulating coupling on the downstream connection to the existing water main, and add a bonding wire from the first piece of DIP to the first 900 bend on the upstream side of the meters. 12. Test stations shown on sheets C-2 and C-3 shall be per SPU Standards. 13, In the Specifications, 8-23.1, second paragraph, end of second line, change "Reinforcement" to "Recommended". 14. In general, neither the City of Renton nor the Contractor shall operate any SPU-owned valves. SPU shall be notified at least three work days before the need to have a shut down of a service line. 15.

City of Renton March 8, 2001 Mr. Charles Madden, P.E. Seattle Public Utilities Dexter Horton Building, 7th Floor 710 Second Avenue Seattle, WA 98194 SUBJECT: Relocation of Water Meters for Boeing Plant in Renton Dear Charlie: Thank you for the detailed review of our preliminary design plans. We have gone through your comments and have revised the plans accordingly. Enclosed are two sets of revised plans for your review. We would like to advertise this project for bidding in March 2001 and start construction in April 2001. The following is our response to Jim Wilkes' review comments dated December 20, 2000. Sheet C-1, Plan View 1. East Service has a6" SS crossing over the water line very close to the water meter vault. Replace this crossing with one length of ductile iron pipe, centered over the water line. Alternatively, can the east service be moved south to the vicinity of the driveway between "house No. 126 and No 150? See note: Existing 6" PVC SS to be replaced with 6" DI, on East Vault Plan View. It would be more complicated to move the vault between house no. 126 and house No. 150, there is an exit lane from Washington Mutual drive through banking. 2. Please furnish stationing for each bend. Stationing has been provided for each bend. 3. Two callouts for the proposed meter refer to SPUPIan#735-7. Since this plan has not been signed and changes may be made by the time it is adopted, we request that you delete reference to this unapproved standard plan on your drawings. Reference to SPU Plan#735-7 has been deleted. Sheet C-1. East & West Profiles 1. Reference to Sheet C-2 should be C-3. In East Profile detail reference has been changed to C-3. 2. The callout for Exist. Ground Elevation at Roadway Centerline should show the existing ground over the waterline, whether in the street or in the sidewalk New callouts are referencing Existing Sidewalk and Existing Driveway elevations. Page 2 March 8, 2001 3. Provide a minimum of two courses of brick and mortar under ring and covers for adjustability. The current design allows 10.2 foot (f2.5 inches) in which to place the 19-inch high ring and cpver (and excluding brick and mortar). The higher sidewalk elevation will help, but sufficient depth of cover should be checked.

The calculations for Shackle rods appear to be inconsistent with the features of this project. Specifically: A. The last review comments specified that SPU normally uses both 3/-inch and 1-inch diameter shackle rods made of ASTMA36 steel round bars which is fusion bonded epoxy coated. Spu does not use ASTMA242 heat treated. High strength Cor-Ten steel in shackle rods. B. SPU does not allow all -thread rod for use in shackle reds. C. The design for shackle rods need to be compatible with the standard materials SPU uses in order that arty future work or modifications will not be under -designed. D. Draging conflict: Shackle rod coating on material lists for both meters is called out as fusion bonded epoxy (which is accaptable to SPL9 but this sheet calls for hot -dipped galvanized without fusion bonded epoxy coating ( which is not acceptable to SPL9 The shackle rodding design has been changed; a. Using 4 each 3/4" diameter rod for 10" diameter pipe and 4 each 1" diameter rod for 14" diameter pipe. Shackle rods are made of ASTM A36 steel round bars which is fusion bonded epoxy coated. b. The rod ends has only have 6-inch of thread cut on each end. c. The design is compatible with the standard materials SPU uses. d. Drawing conflict has been corrected. Please see detail 2 of sheet C-4 and Special Provisions section: 7-11.3(6)E. 2. Renton standard method for sizing concrete thrust block is noted, but a thrust block design specific to this project could not be found. Concrete thrust block sizing has been updated. Required minimum bearing area against undisturbed soil is 33 square feet. Please see detail 1 of sheet C-4. 3. Star National Products claims that their SST 747 Tie Bolts are suitable for use with 1-inch shackle rods. SST 747 Tie Bolts are used. 4. The inclusion of the SPU Type 361 Ring and Cover details may not be needed now since review by other SPU staff has requested these large meter vaults to be fitted with larger ring and covers as mentioned previously. The personnel access opening frame and cover is manufactured by Utility Vault Co. UV#3620-H2O, w/4" riser and cam type locking device.

I also included the companion Standard Plans which describe the whole issue of concrete blocking. Please understand that these standards are for 12-inch and below. Larger water mains are not covered and their test pressures are 250 psi, generally speaking. Of course, when the diameter gets really large, we do a custom design. If you have questions or need clarification, please give me a call. - Jim Boeing -Renton Meters FAX02.doc Date:6/30/00 e-mail from Jim Wilke-SPU- jim.wilke(n ci.seattle.wa.us forwarded by J.D. Wilson with Cad Files saved in H/water/abdoul/spu/standard details Abdoul: Below is the text of an e-mail I received from Jim Wilke of SPU regarding the relocation of the Seattle Meters. 1 have placed copies of the AutoCAD drawings of the Seattle Standard Details in a folder on H drive. J.D. Six sample drawings are being sent via three compressed zip files in three emails due to file size limitations. I have furnished a number of arrangements for 10-inch Meters on 12-inch service lines that have been used or proposed for use on past projects. The details certainly very quite a bit as you will see. And, I'm certain your conditions will vary from all of these! That's sort of the way it is with large services in crowded conditions. Please note that these drawings were developed over several years and so the drafting methods and layers will vary from drawing to drawing (sorry). Your design criteria should include the following: 1. Working Clearance Clearance between equipment and walls/other equipment is 18" if at all possible for entering and tightening clearances for both personnel and tools. 2. Strainer Clearance Distance between pipe centerline and overhead obstructions should be a minimum of 36 inches to enable strainer to be removed and cleaned. — 3 3. Meter Thrust Restraint $rovide thrust restraint for meter isolation gate valves for both upstream and downstream gate valves when meter is removed. 4. Tees on Bypass `� Attach bypass valves directly to the Tees due to SPU policy concerning stagnant water in dead end piping. 5. Ball Corps / Provide 1-1/2" x 2" ball -style corps, AWWA x IPT on the main line and bypass for drain and air -bleed purposes. ✓ 6. Flexibility Provide flexible joints (mechanical joints are fine) near the vault walls (both inside and outside) and at both bypass bends. 7. Floor Depth ✓ Try to keep the top of the meter within 30"-36" of the floor. This is not a firm requirement if other considerations can not be met. The objective is to have access to the top of the meter at an appropriate, accessible work height. 8. Personnel Access Ensure access into vault by permanently installed ladder, with ladder extension. Use WISHA regulations as a guideline. SPU standard service installation practice is to locate services where they can be accessed from non -traffic locations. Access from a non -driving surface shall be through a 3-foot square hatch. Access from driving surfaces (ONLY AS ABSOLUTELY NECESSARY) shall be through a manhole Ring and Cover per Seattle Standard Plan 361, with a 30-inch minimum inside diameter riser and vault top opening below that. 9. Vault Thrust Restraint Systems Thrust restraint shall be by two sets of 1-inch, fusion bonded epoxy coated, mild steel (ASTM A36) shackle rods. SPU does not use Megalugs, Uniflanges, Gripper rings etc. for permanent joint restraint. 10. Buried Thrust Restraint Backup all buried shackle rods at bends and reducers etc. with concrete thrust blocks conforming to Seattle Standard Plans. Apply Royston Roskote 612XM or Trenton Wax Tape Primer and Tape to all buried bare metal such as nuts and threaded rod ends. 11. Equipment Access Place a large diameter HS-20 rated equipment ring and cover over the meter, suitably sized to enable removal of the meter if needed. A large diameter ring and cover with inset auxiliary cover is preferred. —� 12.Supports Support meter, meter isolation gate valves, and bypass piping from vault floor using "Standon" pipe supports, or equal. t� 13. Vault Wall Penetrations Use 2 inches of plastic foam ("Ethafoam", or equal) around pipe through vault walls for settlement concerns. 14. Pipe and Fittings Use ductile iron pipe and fittings per AWWA standards. 15. Connection to Existing Pipe Use a mechanical coupling designed to transition between existing pipe O.D. and the ductile iron Pipe. Observe need for thrust restraint at the upstream and downstream meter isolation gate valves. 16. Flange Insulating Kit A flange insulating kit will be required at the last flange before the pipe leaves the vault down stream of the meter. 17. Union Point The union point is the contractual connection point at which SPU serves the customer. Everything upstream of the union point is SPU owned and operated. Everything downstream belongs and is maintained by the customer. The union point for SPU services is the flange on the hub and flange outside the vault on the tail run of the meter. Restrain the hub and flange to SPU's piping. 18. Corrosion Protection H/water/abdoul/spu/meter 01.doc �—{3 ✓ Boeing has requested that corrosion protection anode and test station be installed on their piping. This should be installed downstream of the union point. 19. Seattle Standards Please design the service using Seattle Standard Plans and Specifications. About the attached drawings: The attached samples have different features. Four sample meter arrangements are presented. The sample that may be of greatest help to you is the three -drawing set for Sample 2. 1 mention this because it is a self restraining vault type design ... a feature you may need in this location. Sample 2 actually has two side by side meter vaults. The one of interest to your project is the smaller vault. The other related sheets show sections and details. Sample 1 has half of the bypass outside the vault, and a smaller vault. Thrust restraint on this project is by restrained joint Pipe, a feature not available to you on the present project. You will need to find a restraint method. Sample 3 is a unique design for an above ground meter. Some of the features may be of use to you. Sample 4 has both inside and half -outside bypasses. It also has a 3-D representation of the special small vault which is currently being proposed for an off -road service location. However, the small vault dimensions should be checked with Utility Vault or what ever your supplier is to make sure it can be built to your site's loading conditions. I may have forgotten something. So if you have any questions, feel free to contact me and I'll try to help.

Change quantitiy, size and description of Keyed Note 424 to the following: Quantity: 2 Size: 1 `/z" x 2" Description: Ballcorp, AWWA Taper x IPT (Ford Meter Box Co. FB800-6, or equal) 11. Note 2: Verify either 28" Diameter opening or 24" Diameter as dimensioned. 12. Provide support for both Keyed Note 9 fittings. 13. Provide Keyed Note 24 on top and bottom of bypass pipe. 14. Please show two courses of brick and mortar under ring and covers. 15. Delete the City of Seattle seal just above the title block. 16. In plan view, there is confusion related to all the Note callouts for Notes 3, 5, and 6 where the pipe enters the south side of the vault. Note 5 does not belong here. V 17. The drawing scale is shown three different ways. LC=- 2 V 18. SPU questions the size and number of shackle rods used on the 14-inch ductile iron pipe. 6� Please see comment 1. Under sheet C-4. 19. In case of a flooded vault, put valve boxes above the gate valves with operating stems. 20. Provide drain for vault into vault granular bedding material (pea gravel). 12/27/00 WED 11:53 FAX 206 684 8535 SPU WATER ENGINEERING W Abdoul G : four 1 December 20, 2000 Pave 4 heA C-3, East Meter Vault 1.

The line under Keyed Note 25 should be moved above the keyed note. Sheet CA, Details 1. The calculations for shackle rods appear to be inconsistent with the features of this project. Specifically: A. The last review comments specified that SPU normally uses both'/ -inch and 1-inch diameter shackle rods made of ASTM A36 steel round bars vy-is-fusion bonded epoxy _roated. SPU does not use ASTM A242 heat treated, high strength Cor-Ten steel in shacTde rods. B. SPU does not allow all -thread rod for use in shackle rods. C. The design for the shackle rods needs to be compatible with the standard materials SPU uses in order that any future work or modifications will not be under -designed. D. Drawing conflict: Shackle rod coating on material lists for both meters is called out as fusion bonded epoxy (which is acceptable to SPU) but this sheet calls for hot -dipped galvanized without fusion bonded epoxy coating (which is not acceptable to SPU). For your information only, historic SPUselection ofshackle rod numbers and siring was based on the AISC Steel Construction Manual, 8" Ed., which presents an allowable tensile stress (Ft) of 19.1 Ksi across the nominal diameter of an ASTM A36 threaded fastener. This value was used by SPUfor normal design pressures. SPUalso allows a factor of 1.25 * Ft for surges and test pressures, which includes the 250 psi your design uses. Based on this information, four 1-inch rods would be adequate and would decrease complexity of the shackle system. Of course, your design criteria and design results may be different. 2. Renton's standard method for sizing concrete thrust blocks is noted, but a thrust block design specific to this project could not be found. 3. Star National Products claims that their SST 747 Tie Bolts are suitable for use with 1-inch shackle rods. \_ j 4. The inclusion of the SPU Type 361 Ring and Cover details may not be needed now since review by other SPU staff has requested these large meter vaults to be fitted with larger ring and covers as mentioned previously. 5.
