Flatter, P.E., Director of Public Works SIG NATU~ APPROVED BY CITY ADMINISTRATOR: Michael L. Guttman SIGNATURE~--------~ ITEM SUMMARY: Within the Fiscal Year 2021 Water Fund Budget, money has been included for professional engineering design services related to the rehabilitation of the 500,000 gallon ground storage tank associated with Booster Station #8, located at located at 1255 Helena Drive. Construction associated with the Booster Station #8 Ground Storage Tank Rehabilitation Project is anticipated to commence in spring of Fiscal Year 2022. Booster Station #8, its associated ground storage tank, and Well Station #8 (shallow well) were initially constructed together in 1989. No major improvements have been completed at Booster Station #8 or the associated ground storage tank since its original construction. In 2020, the City hired KLM Engineering, Inc. (KLM) of Woodbury, Minnesota, to evaluate the condition of the Booster Station #8 ground storage tank, and draft an inspection report. KLM's inspection report (attached) identified that after more than 31 years of service life, rehabilitation of the structure is required. Required improvements include, but are not limited to, the following: • Sandblasting and repaint of the tank's exterior. • Removal of obsolete equipment from the interior of the tank (i.e., Cathodic Protection System, brackets, conduits, junction boxes, etc.). • Seam weld and repair interior joints, seams, and supports. • Sandblast and repaint the tank's interior. • Installation of a mixing system inside the tank to improve water quality. • Installation of OSHA approved safety features. Estimate cost of required improvements range between $330,000.00 and $355,000.00. Competitive bids will be sought for construction once engineering design plans, specifications, and bid documents are finalized. Being most familiar with the condition of the storage tank and repairs needed, City staff asked KLM for a proposal to provide professional engineering design services related to the Booster Station #8 Ground Storage Tank Rehabilitation Project. Services will include, but not be limited to, development of design plans, development of project specifications, development of bid documents, providing assistance during the bidding process, and construction oversight services. KLM submitted a cost proposal of $56,344.00. Therefore, it is staff's recommendation that a contract be awarded to KLM Engineering, Inc. of ===== PDF PAGE 32 ===== [Extraction: embedded PDF text] CITY OF WEST CHICAGO Woodbury, Minnesota, for professional engineering services related to the Booster Station #8 Ground Storage Tank Rehabilitation Project, for an amount not to exceed $56,344.00.

KLM has a staff with the most credentials associated with AWS welding and NACE coating inspections of water storage tanks in the five-state area. When it comes to quality inspections on water towers, KLM sets the standard that other companies try to duplicate. Our dedication to quality inspections can be seen nationally as our projects are represented each year in Tnemec's Tank of the Year calendar contest. Elgin, Illinois Kenosha, Wisconsin Joliet, Illinois Copyright 2021 by KLM Engineering, Inc. Page 1 ===== PDF PAGE 35 ===== [Extraction: embedded PDF text] KLM's personnel have been working on water towers since the 1970s. We have tanks that were constructed and painted in the mid-1980s that are just coming up on their first reconditioning. KLM anticipates the tower's coating systems will be in service 20-plus years. This is due to KLM professionals trained to perform proper inspections and holding contractors accountable for quality workmanship. Our inspections are performed by a professional staff with current and proper credentials. Our inspectors who, work directly under our Structural Engineer and Project Supervisor are certified as both NACE and AWS inspectors. Each employee takes ownership of their project. Our professional staff has a combined 150 years of experience and have successfully completed over 500 rehabilitations of water towers of various sizes. The KLM staff is fluent in the current codes and standards for new and reconditioned water tower projects. KLM inspectors climb the towers daily to accept or reject the workmanship of the day. The main reason owners hire a professional consultant is to protect the owner's investment. The average tank without a professional inspection usually needs to be repaired after fifteen years compared to KLM projects, which are lasting 20 or more years. No firm receives respect from tank contractors and subcontractors like KLM. Our role is to provide quality assurance and enforce the specification. KLM is very thorough with our documentation of what and how the work is being performed each day. KLM's reputation of quality is second to none. We stand behind every project we work on. KLM would like to assist you with our expertise on quality control which will make this a successful project for many years to come. By selecting KLM, you can be assured that the project will be completed to your satisfaction. We look forward to working with you. Sincerely, KLM ENGINEERING, INC.

KM Ss Copyright 2021 by KLM Engineering, Inc. ===== PDF PAGE 37 ===== [Extraction: OCR (rendered-page OCR)] Proposal ===== PDF PAGE 38 ===== [Extraction: embedded PDF text] Project Understanding KLM thoroughly reviewed the requirements for the Number 8 Booster~~-----~Station as to fulfill............. the needs of the city. KLM's evaluation report from 2019 and additional records were considered in the preparation of this proposal. Key project team members were brought together to review the previous recommendations and to bring the tower into compliance with current codes, standards and desires of the city. Benefits to the Cit of West Chicago - ----- • Today's protective coating systems are designed to last 20-25 years with only minor maintenance. Tight project specifications and full-time inspections give the coating systems the opportunity to realize their intended service life. • KLM proposes to prepare a specification package specifically designed for water tower reconditioning. Our experience has shown that the more comprehensive the specification is, the more likely it is that the project is completed on time, on budget, with quality workmanship. The KLM specifications will mitigate requests for change orders during reconditioning . • Welding and full time NACE Coating Inspections during reconditioning assures that the work performed by the contractor is in conformance with the specifications, as to maximize its life expectancy. KLM's inspectors monitor workmanship during all phases of work to verify the contractor's work meets the specification. Utilizing this process, maintenance costs will be reduced by decreasing the number of reconditioning cycles over the life of the tank. • Our project administration and inspection services provide a buffer between the project specifications and the real-world challenges that can negatively affect project performance. To initiate the project correctly, KLM's project management assures that a qualified contractor is retained at an appropriate cost.

KLM has planned, designed, and refurbished water towers for the past twenty years. The longevity of our projects is what we are most proud of. What owners most appreciate is the return in investment KLM brings to each rehabilitation project. The following pages list projects KLM has completed, like the proposed tower for the City of Roseau. Reconditioning Project Profiles; City of Eden Prairie, MN Market Center Tower Reconditioning of: 2,000,000 Gallon Composite Dates of Service: 2016 Reconditioning Conditions & Services: The Market Center Tower is an iconic structure for the City, with working clocks on the main column. Given the high profile, size, and challenging location of this tower, the City Manager (Rick Wahlen) performed detailed interviews with each bidding consultant and their staff, to select the best qualified firm to provide the engineering and inspection services required by the City. As the awarded consultant, KLM provided design services, construction management, full time AWS welding and NACE coating inspections throughout the duration of the project. Rick was instrumental in the project from the beginning of pre-construction to the final walk through and close out, including personally climbing the tower regularly to confirm the project had met his standards. Given the tight confines of the jobsite, KLM conducted weekly meetings locally to update the neighboring businesses and residents as the project commenced. The project was successful, being completed on time and within budget. *2017 Tnemec Tank of the Year 2nd Runner Up City of Elgin, IL Randall Road Tower Reconditioning of: 1,000,000 Gallon Single Pedestal Dates of Service: 2016 Evaluation, 2017 Reconditioning Conditions & Services: A project of this size combined with a short schedule may intimidate some contractors and inspection firms. With the combined efforts of a local contractor and KLM, this successful project was completed on time and within budget. Antenna relocation also played a large part of the project. The efficiency of all parties involved allowed telecommunications to operate without disruption. Copyright 2021 by KLM Engineering, Inc.

KLM worked with the Utilities Supervisor on the project to provide plans and specifications. A qualified contractor was selected to perform the reconditioning of the tower. A full containment system was utilized during the project. KLM provided construction management, full time AWS, NACE inspectors, and antenna management throughout the project. A new logo was painted on two sides of the tower; choosing Tnemec Hydroflon for the topcoat on the exterior of the tower. The tower can be seen from Hwy 35W & 23. City of Maple Grove, MN Fish Lake Tower Reconditioning of: 1,500,000 Gallon Hydropillar Dates of Service: 2011 Mixer, 2014 Evaluation, 2015 Reconditioning Conditions & Services: This water tower project included a pre-assessment of the conditions, including an updated engineer cost estimate. Plans and specifications were approved as well as a qualified contactor during the bid process. KLM worked with the contractor on submittals including coating selection, drawing reviews, scheduling and more. KLM's Antenna Division worked with multiple cellular carriers to coordinate efforts of relocating cellular equipment to temporary locations during the reconditioning of the tower. KLM conducted weekly meetings on site to synchronize the efforts of the city, engineer, and contractor(s) as the project commenced. The project was successful being completed on time and within budget. Copyright 2021 by KLM Engineering, Inc.

KLM Engineering, Inc. Proposal. b. General guidelines of AWWA Manual M42 Appendix C "Inspecting and Repairing Steel Water Tanks, and Elevated Tanks for Water Storage." c. KLM "Procedures and Guidelines for Inspecting Existing Steel and Concrete Water Storage Tanks." d. Appendix C Inspection and Evaluation Methods. Based on the inspection data, it appears that some miscellaneous structural modifications and repairs are required. These modifications and repairs serve to bring the reservoir into compliance with OSHA regulations and AWWA standards, allow for better coating bonding, allow for safer access in and on the reservoir and, in some cases, removing unnecessary items. ? .?!Co 1!1n9 Lv;:1luc11:1on ;)u1nn1 .1ry 2.2.1 ILead and Chromium Content Analysis The total lead and chromium content of the interior and exterior coatings were analyzed. The results in Appendix D show a percent lead content below reporting limits for both the interior wet and exterior coatings. Neither coating is classified as lead-based paint. Chromium in the test samples indicate levels from below reporting limits to 0.0038 percent, levels not high enough to be a concern in the waste streams generated during reconditioning. Levels over 0.50 percent chromium could possibly pose problems in waste streams. 2.2.211nterior Wet Coating The reservoir was constructed, and interior wet area originally coated, by Advance Tank Company in 1989. Although records are not available, field data shows evidence of prior spot repair attempts estimated to have been performed approximately 10 years ago. The interior coating is in poor condition above the High-Water Line (HWL) with more than 90 percent visible coating failures. Failures consist of widespread peeling and surface corrosion on the roof plates and early stages of aggressive corrosion on the roof support structure. The coating below the HWL is in poor condition with approximately 25 percent visible coating failures. Failures consist mostly of widespread pinhole corrosion throughout the reservoir. Due to age and condition, the interior coating is not a candidate for repairs and should be replaced in its entirety within one (1) year to maximize the life expectancy of the structure. See photos in Appendix A. 2.2.31Exterior Coating Based on conditions, field data suggests the exterior was presumably overcoated at the same time as the interior repairs, approximately 10 years ago. The exterior coating is in poor overall condition with widespread Copyright 2020 by KLM Engineering, Inc. Page3 ===== PDF PAGE 64 ===== [Extraction: embedded PDF text] HELENA DRIVE RESERVOIR CITY OF WEST CHICAGO, ILLINOIS oxidation from UV degradation, exposing the underlying coatings. Oxidation will continue to accelerate, eventually breaking down the underlying coating and exposing the substrate. Due to unknown age, surface preparation and overall condition, the exterior is not considered a candidate for additional overcoats. While the coating could last a couple more years, to manage reservoir reconditioning more cost-effectively, the coating should be replaced in its entirety at the same time as the interior coatings, within one (1) year. See photos in Appendix A. ? 311~ e p '" i r a n d f~ e co n cl i ti o n i 11 ~l Cost Est i n: at o The costs for structural repairs and replacing the interior and exterior coatings are estimated between $330,000 and $355,000. This estimate is based on current pricing and does not include costs for engineering and/or inspection services. For competitive bids, the project should be bid 9 to 12 months before the desired starting date. An experienced reservoir-coating contractor with proper crew and equipment should be able to complete the project in nine (9) weeks. At the time of reconditioning, the reservoir will need to be drained and remain off-line during interior structural modifications, abrasive blasting, and painting. However, most of the exterior structural modifications can be performed prior to draining, with the reservoir in-service. Based on the inspection data, if the recommended structural repairs and coating replacement are completed within one (1) year, the reservoir will be satisfactory for continued service, provided it is inspected regularly. Upon reconditioning, the reservoir and coating should first be inspected within the warranty period and every three (3) to five (5) years thereafter. A new interior and exterior coating, if applied and maintained properly, should last at least 20 years. 3.0IRECOMMENDATIONS The photographs referred to in this section are in Appendix A. The surface preparation requirements for all repairs as well as the requirements for welding are described in Appendix B. The exterior and interior paint chip lead tests are in Appendix D. Based on an evaluation of the inspection data, the following are our recommendations: 3. lllnteriof" Wet 3truci:11rai 3.1.1 Seal weld the inside of the joint between the roof plate and the roof access manway. This weld will prevent rust streaking and corrosion in areas inaccessible to paint. 3.1.2 Seal weld all 27 bolted roof-framing connections at the outer roof with a 3/16-inch fillet weld. After welding, remove all nuts and bolts. See photos 3 through 5, and 7 and 8. 3.1.3 Seal weld all 27 connections where roof rafters attach to the center compression ring. See photo 2. 3.1.4 Install one (1) 18-inch diameter by 12-inch deep sump pit in the reservoir floor adjacent to the shell manway. This will facilitate future draining and cleaning. See KLM Drawing No. 52c. 3.1.5 Seal weld all seams between the central column support foot and the floor, per AWWA D100-11 . See photo 17. Copyright 2020 by KLM Engineering, Inc. Page4 ===== PDF PAGE 65 ===== [Extraction: embedded PDF text] HELENA DRIVE RESERVOIR CITY OF WEST CHICAGO, ILLINOIS 3.1.6 Remove the existing cathodic protection system from inside the reservoir. Remove all brackets, conduit, cables, junction boxes, etc. Patch any resulting holes according to Appendix C and AWWA D100-11 . See photos 13, 14 and 30. 3.1.7 Remove all weld spatter and scab marks below the HWL by air arc gouging, cutting torch, and/or grinding to comply with AWWA D100-11. Prepare the surface per Appendix C. It is estimated that there are 55 man-hours to perform the work. 3.1.8 Upon completion of blasting and painting operations install NSF 61 approved rubber neoprene barriers at all connections where the fill pipe rests on the supports. See photos 17 and 18. 3.1.9 Replace the gaskets on the two (2) 24-inch diameter round shell manways. See photos 14 and 27. 3.1.10 Install a Grid-Bee GS-12 Submersible Mixer in the reservoir to provide mixing capabilities that reduce the likelihood and magnitude of ice formation in cold weather and prevent stratification in warm weather, improving water quality and reducing the necessity of chemical additives such as chlorine. Include the installation of all electrical components and control panel for proper operation through SCADA systems. Refer to KLM Drawing No. 58. 3.2 11ntcrror Wet Coatmg 3.2.1 Past coating repairs have been unsuccessful in stopping the corrosion on the interior wet surfaces below the High-Water Line. Apparent improper surface preparation of the coatings has resulted in widespread delamination and corrosion throughout the reservoir interior. The interior wet coating is not repairable and should be replaced in its entirety within one (1) year to maximize the life expectancy of the structure. See photos 2 through 19. 3.2.2 After structural repairs are completed, all the reservoir surfaces should be abrasive blasted to an SSPC-SP-10 Near White Metal Blast and coated with a light-colored zinc/polyamide epoxy system (similar to the Tnemec Series 91-H20 Hydro-Zinc/Series N140 Pota-Pox Plus Epoxy coatings). 3.3.1 The reservoir has a submerged C. P. system. The corrosion and pitting that is occurring suggests the C. P. system is not working correctly. It also should be noted, C.P. systems are not effective at protecting the reservoir surfaces above the HWL. With the recommended zinc rich primer, cathodic protection is not necessarily required, which can provide long term cost savings. As noted in item 3.1.5, KLM recommends removing the C.P. system in its entirety. j , :, - _, 1. , • I 3.4.1 Replace the non-compliant reservoir venUfinial with a 24-inch diameter aluminum pressure pallet style vent, similar to the one shown on KLM Drawing No. Ba. The new vent and vent screen design should meet AWWA D100-11 and local Health Department Regulations. The removable top will improve ventilation, provide access to the reservoir interior during reconditioning, and aid in compliance with OSHA Confined Space Entry Requirements. See photo 20. 3.4.2 Install three (3) 24-inch round, hinged cover, roof ventilation manway(s), approximately 90 degrees from the existing/lower roof manway. This will provide additional ventilation during the interior surface preparation and coating and the reservoir should comply with OSHA Confined Space Entry Requirements. See KLM Drawing No. 10a.

Repair the resulting hole per AWWA D100-11. Seal weld both inside and outside. See photo 25. 3.4.4 Install pipe style roof edge handrail system similar to KLM Drawing No. 16b. See photo 23. 3.4.5 Relocate the roof access manway so as not to be in alignment with the shell ladder and keeping it within the new handrail. Current conditions are not OSHA Compliant with the manway, creating a trip hazard while gaining access onto the roof. Repair the resulting hole per AWWA 0100-11 . Seal weld inside and outside.

Refer to KLM Drawing No. 24b. 3.4.7 Replace the pipe style safety climb device on the shell ladder with an OSHA approved cable style device. 3.4.8 According to Ten States Standards, replace the overflow pipe discharge screen with a corrosion resistant, heavy gauge, #24 mesh screen. See photos 28 and 29. 3.4.9 Remove the abandoned aerator structure in its entirety, adjacent to the reservoir. See photos 24, 28, 32, and 33. 3.5.1 The exterior coating is in poor overall condition with widespread oxidation from UV degradation, exposing the underlying coatings. Oxidation will continue to accelerate, eventually breaking down the underlying coating and exposing the substrate. Due to unknown age, surface preparation and overall condition, the exterior is not considered a candidate for additional overcoats.

Antennas generally have the effect of dramatically increasing the cost of reconditioning water storage reservoirs. If the owner is considering allowing antennas to be installed on the reservoir, lease agreements should be written to ensure the antenna owners are responsible for increase maintenance costs due to their presence. Installations should be reviewed to ensure that they do not interfere with normal use or maintenance of the reservoir, present safety hazards, or violate state or federal regulations.

As the corrosiveness of the product increases, the design and fabrication of the tank or vessel becomes more critical relative to the performance of the lining. This standard presents standard practices for the design, fabrication, and surface finish of metal tanks and vessels that are to be lined for corrosion resistance and to prevent product contamination. The standard explains how the standard practices govern the quality of lining applications. Appendix A contains illustrations depicting both good and bad practices for tanks and vessels to be lined, and Appendix 8 contains a list of recommended responsibilities to ensure that an acceptable lining application is achieved. Appendix C contains written and graphic descriptions of five dewees of surface preparation of welds in tanks and vessels that may be specified prior to lining. l This standard is intended for use or reference by end users, lining specifiers, lining applicators, lining manufacturers, and contracting authorities involved in the surface preparation or lining installation in tanks and vessels intended for chemical immersion service. This standard practice was originally prepared in 1978 by NACE International Task Group (TG) T- 6A-29, a component of Unit Committee T-6A on Coating and Lining Materials for Immersion Service, in collaboration with Unit Committee T-6H on Application and Use of Coatings for Atmospheric Service. The standard was revised in 1989 by TG T-6G-27, a component of Unit Committee T-6G on Surface Preparation for Protective Coatings, and was reaffirmed in 1991 and 1995. It was reaffirmed in 2003 by Specific Technology Group (STG) 04 on Coatings and Linings, Protective: Surface Preparation. The standard was revised in 2007 by TG 295 on Lining, Tanks and Vessels for Immersion Service: Fabrication Details, Surface Finish Requirements, and Proper Design Considerations-Review of NACE Standard RP0178-2003. This TG is administered by STG 04. It is also sponsored by STG 02 on Coatings and Linings, Protective: Atmospheric; STG 03 on Coatings and Linings, Protective: Immersion and Buried Service; and STG 43 on Transportation, Land. This standard is issued by NACE International under the auspices of STG 04. <1> The visual comparator mentioned in Appendix C is a molded plastic replica that illustrates various degrees of surface finishing for welds prior to coating or lining.

If a lining is then applied to the steel and part of the alloy (usually 150 to 610 mm [5.9 to 24 in.]), any discontinuity in the lining exposes a small anode surface. Once corrosion starts, it progresses rapidly because of the large exposed alloy cathodic area to the much smaller anodic area. Without the lining, galvanic corrosion causes the steel to corrode at the weld area, but at a much slower rate. The recommended practice is to apply lining to all of the alloy as well as the steel, thereby eliminating the possible occurrence of a large-cathode-to small-anode surface.

Where possible, the base metal and coating on the interior wet surfaces were examined from either a rubber raft while the tank was being drained, by a Remote Operated Vehicle (ROV) with the tower in service, or with both. 1.1.2 Tank plate thickness was measured at random locations on the liquid holding shell. The overall structural condition of the tank was visually examined. 1.1.3 No structural analysis was done to determine if the tank design complies with the AWWA 0100-11 Standard for "Welded Carbon Steel Tanks for Water Storage." However, any observed non-conformance to theAWWA 0100-11 standard is noted in this report. 1.1.4 Although compliance with OSHA regulations was not a part of this inspection, any unsafe conditions or violations of current OSHA regulation that were observed are noted in this report. 1 ? F Some or all of the following procedures were performed as applicable. 1.2.11Site The tank site was evaluated for proper drainage conditions affecting access and lead paint abatement during reconditioning. Also, the following site dimensions were obtained: distance to fence(s}, power lines, owner buildings, public property, private property/buildings, school/playgrounds, public parks, and other property. 1.2.21Foundations The tank concrete foundation(s) were/was visually examined for cracks, spalling, conditions of grout, indications of distress/settlement, and elevation above grade. 1.2.31Tank Plate Thickness Plate thickness measurements were taken using ultrasonic methods (UTM). The readings were taken using a digital readout Nova 0-100 Ultrasonic Thickness Gage that has a dual element probe (transducer). The probe's transmitter element sends a short ultrasonic pulse to the material. The pulse, reflected as an echo from the opposite side of the plate Copyright 2020 by KLM Engineering, Inc. Page 1 ===== PDF PAGE 108 ===== [Extraction: embedded PDF text] returns to the probe's receiver element. The round-trip time is directly related to the material's thickness. 1.2.41Coating Thickness Interior and exterior coatings, where accessible, were tested in accordance with Steel Structures Painting Council SSPC-PA2-82 "Measurement of Dry Film Thickness with Magnetic Gages" using PosiTector-6000-F1 Type 2 magnet flux gages with a fixed probe. 1.2.SjCoating Adhesion Adhesion testing of the coating to the steel was performed by ASTM D-3359: Shear Adhesion Test, Measuring Adhesion by Tape Test. In addition, subjective coating adhesion evaluation was performed using a penknife. 1.2.6jCoating Cure The cure of the interior wet coating was evaluated by ASTM D-5402-93 Standard Practice for Assessing the Solvent Resistance of Organic Coatings Using Solvent Rubs and/or with the manufacturer's recommended field method/industry standard procedures. 1.2. 7jCoating Serviceability The estimated remaining coating life or serviceability evaluation was performed using a wide variety of inspection instruments such as dry film thickness gauge, pen knife, Tooke gauge, adhesion tester(s), 30x microscope and serviceability evaluation experience (minimum experience 10 years). The instrument inspection wa_s combined with a close visual inspection of all the interior coating's accessible areas. This was done to detect any holidays (misses), skips, runs, sags, surface containments, overspray, dry spray, poor coating cohesion, inter-coat delamination, loss of adhesion to the substrate, adverse conditions of the steel underneath the coating, or any other defects affecting the intended service. 1.2.BjCoating Lead and Chromium Content Analysis Samples may have been taken of the various types of coatings present on the interior and exterior surfaces. Corrosion Control Consultants and Labs of Kentwood, Michigan tests these coatings in conformance with ASTM D-3335 Standard Test Methods for Concentrations of Lead and Chromium in Paint.
