Meeting July 21, 2026 - REGULAR MEETING OF THE MOUNT PROSPECT VILLAGE BOARD Fiscal Impact (Y/N) Dollar Amount Budget Source Category Type Information Y $2125388.00 Water and Sewer Enterprise Fund VILLAGE MANAGER'S REPORT Action Item The Village of Mount Prospect owns and operates a 1,000,000-gallon elevated multi -legged steel water tank located in downtown Mount Prospect. As part of the Village's ongoing preventive maintenance program, Tank Industry Consultants was retained in 2023 to conduct a comprehensive inspection of the tank. The purpose of these inspections is to identify and evaluate any changes in the condition of the tank's interior, exposed exterior surfaces, and associated accessories since the previous assessment. During the inspection, it was determined that the elevated water tank requires several maintenance and rehabilitation improvements, including exterior cleaning and repainting with full containment, interior cleaning and coating, welding repairs to the interior shell stiffening angles, repairs to the overflow piping, and safety upgrades necessary to meet current OSHA requirements. A copy of the evaluation is attached. Additionally, staff would like to complete these repairs and modifications in advance of the potential relocation of antenna equipment from 111 E Busse in the downtown to the elevated water storage tank. The elevated water storage tank was last rehabilitated in 2014. In order to complete the necessary repairs and improvements, the tank will need to be taken out of service for an extended period of time. Reauest for Proaosals To design these improvements, staff require technical assistance from a qualified civil engineering consultant. Accordingly, staff prepared a detailed request for proposals (RFP) necessary to solicit these services. Consulting engineers were asked to submit a technical proposal detailing the firm's background, key personnel, and approach to the project. In addition, each firm was also asked to submit a separate cost proposal indicating work effort anticipated and a not -to -exceed fee. The required scope of work includes performing an updated evaluation of the tank; preparation of plans and bid documents; meetings, obtaining all necessary regulatory permits and construction inspection. RFPs were distributed to three local engineering firms and publicized on the Village's OpenBids website. RFP Results Three technical proposals and three cost proposals were received. Each proposal was evaluated based on the background of the firm, related project experience, proposed services and scope of work, scheduled work effort and proposal content. Each firm received a point ranking (total points = 100) for each criterion. Table 1 below summarized this analysis. Table 1: Technical Proposal Evaluation Category Max.

Discussion TIC's proposal included numerous examples of successfully completed reservoir and water tank rehabilitation projects similar in size and scope to the proposed work. Representative projects include the rehabilitation of a 2,000,000-gallon steel pedestal water tank in Dayton, Ohio; a 1,000,000-gallon welded steel elevated water tank in Pensacola, Florida; and a 500,000-gallon multi -column elevated water tank in Marion, Indiana. In addition, TIC provided examples of experience in the design and construction of new water storage facilities, including a 4-million-gallon ground storage water tank in Tennessee. Reference checks conducted by staff indicated that Tank Industry Consultants performed satisfactorily on these projects. A copy of TIC's technical proposal is enclosed. In addition, TIC has successfully completed several engineering projects for the Village over the past 15 years. These projects include the rehabilitation of the elevated water storage tank in 2014, rehabilitation and roof repairs to the 2-million-gallon steel ground storage tank at Booster Station No. 17, rehabilitation of the 1-million-gallon tank at Station 11, and rehabilitation of the 810,000-gallon partially buried concrete tank at Station 4. TIC has also performed inspections and prepared evaluation reports for all seven water storage tanks located throughout the Village. All of their work has been satisfactory. Staff met with and interviewed all three submitting firms to discuss their understanding of the project, the proposed scope of work, and their experience with projects of similar size and complexity. Each firm was asked to submit a cost proposal as well. Table 2 below summarizes staffs analysis of costs. Table 2: Cost Proposals Firm Total Cost Cost Per Hour Baxter &Woodman $96f 605 $220 KLM Engineering $115f 516 No hours provided Tank Industry Consultants $193f 080 $140 The lowest cost proposal was submitted by Baxter & Woodman of Crystal Lake, Illinois. It is staffs opinion that, based on proposals and staff interviews, TIC demonstrated extensive experience with water storage tank rehabilitation projects of similar size, complexity, and scope, as well as its proven familiarity with the Village's water system infrastructure. In addition, staff finds that TIC has allotted an appropriate work effort (1,370 hours) and requested a competitive fee ($140/hour). The Village's elevated water storage tank is one of the most critical components of the water distribution system, providing essential water storage, maintaining system pressure, and ensuring reliable fire protection. Given its vital operational role and its prominent location within the Village's downtown district, both the structural integrity and aesthetic appearance of the tank are of paramount importance. While the proposal from Tank Industry Consultants is approximately $78,000 higher than the next -ranked engineering firm, staff believes the additional investment is justified by the firm's unmatched qualifications, experience, and proven performance. Tank Industry Consultants employs some of the industry's leading engineers, specification writers, and construction inspectors, and has established a national reputation by authoring portions of the American Water Works Association (AWWA) standards governing best practices for water tank maintenance, repair, design, and construction. It can be argued that the firm literally wrote the book on welded steel water tank rehabilitation. TIC's contract specifications are more comprehensive and stringent than those typically provided by other firms, and they are recognized for rigorous inspection services and strict enforcement of contractor compliance, resulting in higher -quality projects and reduced long- term risk to the Village. The firm's performance during the Village's previous elevated tank rehabilitation project was exceptional, and they have also provided invaluable engineering services in developing plans, specifications, and construction inspection for the Village's two previous water tank roof collapse projects. The Village is evaluating this site as a potential long-term solution for relocating existing cellular carrier antennas from the Chase Bank rooftop, which would facilitate future redevelopment opportunities at that property. The viability of this solution improves substantially if a high -quality rehabilitation of the tank is performed prior to adding the antennae. A high -quality rehabilitation of the tank and tank coating system at this juncture avails the best opportunity to minimize the need to rehabilitate the tank while the Chase antennae are mounted. Given the significance of this infrastructure asset, the importance of protecting the Village's long-term investment, and the strategic opportunities associated with the site, staff recommends selecting Tank Industry Consultants despite the higher initial cost, as their expertise and quality of service are expected to provide the greatest long-term value to the Village. In addition to its local experience, TIC provides a strong portfolio of successfully completed elevated and ground storage tank rehabilitation projects throughout the United States, including projects involving complex structural repairs, coating systems, safety upgrades, and tank modifications. The firm's direct experience with similar facilities and its positive reference checks distinguished TIC from other firms considered for the project. A copy of TIC's submitted cost proposal is enclosed. Staff recommend including a 10% contingency in the award for this proposed contract because time spent on construction engineering and inspection can vary due to circumstances beyond the engineering consultant's control. For example, contractor delays, material availability and inclement weather are all parameters that can lengthen anticipated construction time. Inclusion of a 10% contingency (19,308) will increase the project award from $193,080 to $212,388. Alternatives 1. Accept Tank Industry Consultants' proposal for design and construction engineering for the Elevated Water Storage Tank Rehabilitation Project. 2. Action at the discretion of the Village Board. Staff Recommendation Staff recommends that the Village Board accept the proposal for the elevated water storage tank rehabilitation design and construction engineering as submitted by Tank Industry Consultants of Indianapolis, Indiana for an amount not to exceed $212,388.

Prospect, Illinois. The tank. was owned by the Villagi of Mt. Prospect and was known as the "Mt. Prospect Tank." The field evaluation wa� performed on July 20, 2023 by James A. Peyer, NACE Coating Inspector Level 3 Certified, Certificate No. 8743 and Jesse L. Jenkins, NACE Coating Inspector Leve I —Certified,, Certificate No. 108561 of Tank Industry Consultants. The radial con( tank was of welded steel construction. According to the tank nameplate, the tank wa� built in 1955 by Chicago Bridge & Iron Company under contract number 6-8911, an( had a capacity of 1,000,000 gallons. The tank nameplate also stated that the I 0-columi tank was 95 ft to bottom capacity level. Tank Industry Consultants (TIC) provide( detailed specifications and work -in -process project observations when the exterior an( interior were completely blast cleaned and repainted in 1993, and again in 2014 whei the interior was completed blasted cleaned and the exterior was topcoated. TIC als, provided engineering services when antenna work was conducted on the tank. t The purpose of this evaluation was to determine the condition of the tank interior, exterior, exposed foundations, and accessories. As the tank was not drained for the field evaluation,, the interior was evaluated by a remotely operated vehicle (ROV). Therefore, only the shell and bowl surfaces visible by use of the ROV were observed and none of the riser.interior was evaluated. The purpose of this report is to present the findings, to identify structural, sanitary, and safety deencies of the evaluation, and to make recommendations for recoating, repairing, corrosion protection, and maintenance. Budget estimates for the work, anticipated life of the coating and the structurel, and the replacement cost of the tank are also included. This evaluation, disinfection, and report were authorized in the Purchase Order Number 2023-00000313 dated April 11, 2023, and the TIC Standard Form of Agreement, dated April 11, 2023, and signed by Casey Botterman. The exterior coatinia system appeared to be in good condition and providing good corrosion protection. The exterior should not need to be painted within the next 7 to 8 years from a corrosion standpoint. The exterior should be re-evaluated in 3 to 5 years, in accordance with AWWA. recommendations, to determine a more precise recoating schedule. The interior coating system appeared to be in generally good condition and, with the cathodic protection system, providing adequate corrosion protection. The cathodic protection system should be operated and maintained in accordance with manufacturer requirements. TIC recommends that the interior surfaces of this tank be re-evaluated in to 3 to 5 years to determine a recoating schedule. 0 1 Z993MU11= 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt.

Anchor Bolts and Chairs: Each of the columns was equipped with two anchor bolts, and the riser was equipped with six anchor bolts. All of the anchor bolts were equipped with chairs. Corrosion and metal loss were noted on the back side of one of the riser anchor bolt nuts. No other significant areas of corrosion or coating failure were observed on the remaining anchor bolts, nuts, and chairs. (See photos 14-15, 18, 22, 24-25) 4. Column Condition: The columns were of welded steel construction and appeared to be in nearly their original structural condition at the time of the field evaluation. The column coating was in good condition with no significant areas of corrosion or coating failure noted. Mildew was present in areas. Debris was observed in the coating, and the coating had poor adhesion to the shell. A 1 in. diameter threaded and plugged coupling was located near the base of each of the columns. Shrouded antenna equipment was located on the foundations under Columns #8 and # 10. Cables and two conduits extended up Column #8 within a cable tray. Two antennas and a camera were located along Column #8. The proper operation of the camera was not verified at the field evaluation. Two 6 in. diameter pipes extended up Column # 10 from the shroud. A 4-antenna array was located near the top of Column # 10. There were hand holds located on the columns directly beneath the bowl. It is the 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 12 Village of Mt. Prospect, Illinois 22.129.H3 73. 001 opinion of Tank Industry Consultants that the hand holds should not be used for rigging purposes. (See photos 12, 33-34, 36-37, 41-43) 5. Riser Condition: The riser was of welded steel construction and appeared to be in nearly its original structural condition. The riser coating was in good condition. Debris was observed in the coating in a few areas, and the coating had fair adhesion to the steel. Mildew was observed on the lower part of the riser. The tank nameplate was attached to a bracket on the lower part of the riser. Mildew was observed around the perimeter of the nameplate, particularly along its base. A cathodic protection system control cabinet, housing the automatically controlled potential rectifier, was located near the bottom of riser. The riser was equipped with a flanged and bolted manhole. The riser around the flanged and bolted manhole was equipped with a circular reinforcing plate on its exterior. The manhole was equipped with two handles and a hinged support arm on the exterior. A welded steel circular patch plate was adjacent to the manhole reinforcing plate in the lower riser. There were erection brackets and hand holds located around the top of the riser directly beneath the bowl. It is the opinion of Tank Industry Consultants that the erection brackets and hand holds should not be used for rigging purposes. (See photos 20-21, 26-29, 35, 43-44) 6. Diagonal Bracing: The diagonal bracing was equipped with turnbuckles, clevises, and wing plates. The diagonal bracing was of skip -column design. The diagonal bracing coating system appeared to be in good overall condition with no significant areas of corrosion or coating failure noted. The coating had very good adhesion to the steel. Mildew was located on the diagonal bracing rods and clevis connections, primarily near the base of the tower. (See photos 19, 36-37) 7. Column and Riser Rods: The tower was equipped with a set of riser rods and a set of rods from column -to -column just below the bowl. The rods were equipped with turnbuckles and wing plates. The coating appeared to be in good condition with no significant corrosion or coating failure noted. It is the opinion of Tank Industry Consultants that the column -to -column rods and riser rods should not be used for rigging purposes. (See photos 36-37, 42-43) 8. Overflow Pipe: There was an operational deficiency noted: the screening on the overflow pipe flap gate appeared partially occluded. The overflow pipe exited through the roof knuckle and extended down the shell, through a reinforcing plate in the balcony, and down the column before discharging above a funnel pipe which extended below grade. The overflow pipe was equipped with a screened flap gate. The screening appeared to be adequately sized to prevent the ingress of insects into the tank, but the screening was partially occluded. The overflow pipe was welded to brackets which were welded to the column. The overflow pipe and brackets appeared to be in their original structural condition at the time of this field evaluation. No significant coating failure or corrosion were observed. (See photos 30-32, 60, 66, 70) 9. Tower Ladder: The tower was equipped with a ladder which provided access from near grade to the platform below the balcony. The tower ladder was equipped with anotched-tubular safe - climbing device. The tower ladder was welded to brackets which were welded to the column. The tower ladder and brackets appeared to be in nearly their original structural condition at the time of this field evaluation. A ladder gate vandal deterrent was located near the base of the tower ladder. The vandal deterrent was equipped with side panels and was locked prior to and after the field evaluation. (See photos 38-40, 47) 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 13 Village of Mt. Prospect, Illinois 22.129.H3 73. 001 10. Ladder Platform, Stairs, and Ladder to Balcony: There was a safety and OSHA deficiency noted: the platform access opening was not equipped with a self -closing gate. A platform, stairs, and ladder were located below the balcony near the top of the column and provided access from the top of the tower ladder to the balcony. The platform access opening was equipped with two closure chains. The platform was equipped with drain holes, and no evidence of ponding water was noted. The platform and stairs were equipped with railings of welded angle and flat bar construction. (See photos 47-48) 11. Bowl Condition: The bowl coating appeared to be in good overall condition with no significant areas of coating failure or corrosion noted. The coating exhibited very good adhesion to the steel. The coating on the bowl and girders had cracked in a few isolated areas. Mildew was observed on the bowl plates, along a few of the bowl seams, and along the girders. There were hand holds located on the girders. It is the opinion of Tank Industry Consultants that the hand holds should not be used for rigging purposes or personnel access. (See photos 43-46) 12. Balcony Condition: There were safety and OSHA deficiencies noted: (1) the balcony access opening was not equipped with a self -closing gate to deter personnel from inadvertently falling from the balcony, (2) the overflow pipe opening in the balcony floor was not equipped with a 3-1/2 in. tall curb, and (3) conduit extended across the balcony which created a trip hazard. Access to the balcony from the ladder was through an opening in the balcony floor. The access was equipped with a head deflector. Closure chains were located adjacent to either side of the access opening, but the closure chains were not equipped with connecting hasps. The balcony floor was equipped with drain holes; however, random evidence of trapped water was found near the toe bar. The underside of the balcony floor was intermittently welded to the shell and toe bar. The safety railing was of welded and bolted construction. The balcony coating was in good overall condition with no significant areas of failure or corrosion noted. A few coating failures were noted on the balcony handrail, and the coating exhibited fair adhesion to the underlying coating. Two surveillance cameras, 10 dish and pole -mounted antennas, and unused antenna pipe brackets were attached to the outside of the balcony. The proper operation of the surveillance cameras was not verified at the field evaluation. Flexible conduits and cords extended along the balcony floor and safety railing to this equipment. Curbed openings were located through the balcony floor for the cords and flexible conduits. The overflow pipe extended through a welded steel rectangular patch plate which was located within another welded steel rectangular patch plate in the balcony floor. (See photos 49-61) 13. Shell Condition: There was a safety -related deficiency noted: one of the conduits extending up the shell was not attached to all of its brackets. The contour of the tank shell had minor peaking, banding, and flat spots. The shell coating appeared to be in good condition. No significant areas of corrosion or coating failure were noted. Minor skips were observed in the coating, and the coating exhibited good adhesion to the steel. Signs were located on the southwest and northeast sides of the shell. The signs were black lettering with a gray shading and read, "MOUNT PROSPECT." The signs included a red decal logo. The signs and logos were in good condition. Two conduits extended up the shell along welded steel brackets. One of the conduits was not attached to all of its brackets. (See photos 62-65) 14. Exterior Shell and Roof Ladders: There were safety and ANSI/OSHA deficiencies noted: (1) conduits were attached to the ladder brackets that could interfere with the unrestricted use of the side rails by the climber, and (2) coating and corrosion were noted on the safe -climbing device which could prevent its proper operaiton. The shell and roof were equipped 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 14 Village of Mt. Prospect, Illinois 22.129.H3 73.001 with a ladder which provided access from the balcony to near the center of the roof. The shell and roof ladder was equipped with anotched-tubular safe -climbing device, but coating and corrosion on the device may prevent its proper operation. The shell and roof ladder was welded to brackets which were welded to the container. The shell and roof ladder and brackets appeared to be in nearly their original structural condition at the time of this field evaluation. (See photos 66-67, 74-75) 15. Roof Condition: The contour of the roof appeared adequate. The roof coating was in good condition with no significant areas of corrosion or coating failure noted. The coating exhibited good adhesion to the steel. Welded steel circular patch plates, presumably at the locations of previous cathodic protection anode hand holes, were located on the roof. An outer ring of 14 and an inner ring of 7 threaded and plugged 2 in. diameter couplings were located in the roof. Two conduits extended from the top of the roof ladder to a junction box attached to a pole bracket near the roof vent. The other conduit was not used. (See photos 70-72, 75-78) 16. Roof Manhole: The roof was equipped with one hinged cover manhole. The manhole was locked prior to and after this evaluation. The roof manhole was welded on the exterior, and seam sealer had been applied to the interior roof manhole -to -roof plate seam. (See photos 73-74) 17. Roof Vent: The roof was equipped with aclog-resistant vent located at a bolted and flanged opening in the approximate center of the roof. The vent appeared to be equipped with pallets which would facilitate ventilation during filling or draining of the tank. The proper operation of the pallets was not verified during this evaluation. (See photo 75, 79-80) C.

Interior Coating Condition: The tank was not drained for the field evaluation, and the interior evaluation was performed by an ROV. The evaluation of the bowl was significantly limited by the presence of silt on the bowl surfaces, and the interior riser could not be viewed. The visible coating on the interior surfaces of the tank appeared to be in good condition, and in conjunction with the cathodic protection system, providing good corrosion protection. The interior surfaces were coated with an epoxy system. 2. Roof Condition: The coating on the roof plates appeared to be in overall condition. Rust staining was noted along the edges of the roof stiffeners. The interior roof support structure consisted of intermittently welded stiffening members. This included a circular center hub and three sets of radial stiffeners. Flexible sealant was located along the stiffener interface with the roof. (See photos 81-88) 3. Shell Condition: There was an AWWA D100 deficiency noted: the interior shell angle was not fully welded to the shell. The coating on the interior shell appeared to be in good condition with no significant areas of corrosion noted. A stiffening angle was located around the interior shell. The interior shell angle was intermittently welded to the shell, and flexible sealant had been applied. The angle was equipped with drain holes. It is the opinion of Tank Industry Consultants that the interior shell stiffening angle should not be used for rigging purposes. (See photos 88-92) 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 16 Village of Mt. Prospect, Illinois 22.129.H3 73.001 4. Overflow Pipe: The overflow pipe was equipped with an open pipe inlet with an anti - vortex plate. The location of the overflow inlet was such that the top capacity level was even with the unwelded roof plate seams. (See photos 91-92) 5. Bowl Condition: The observed bowl coating appeared to be in good overall condition with no significant areas of corrosion or coating failures noted. The evaluation of the bowl surfaces was limited by the presence of silt. The riser opening in the bowl was equipped with a safety grate which included a hinged access opening. (See photos 93-98) 6. Cathodic Protection System: The container was a equipped with a cathodic protection system. The system consisted of a submerged wire anode with floats. The anode appeared intact. It appeared as though the cathodic protection system was operating properly as no significant corrosion was observed at the areas of coating failure. Two reference electrodes were located just above the bowl. A cathodic protection system control cabinet, housing the automatically controlled potential rectifier, was located near the bottom of riser. (See photos 91-92) RECOMMENDATIONS: A. Foundations and Site 1. Site Maintenance: The site should be maintained so that the top of all foundations project the AWWA recommended minimum of 6 in. above grade and so that proper drainage away from the foundations continues. Site maintenance should be performed with the mower discharge directed away from the base of the tank to prevent rock chips in the coating and the accumulation of grass clippings on the base plates. Any tree limbs growing in close proximity with the tank should be regularly trimmed. 2. Site Access and Restoration: Contractor and heavy equipment access to the site would be difficult due to the small site size. Provisions should be included in the specifications for the restoration of any surfaces and structures disturbed by the contractor's work. 3. Tank and Site Security: Water tanks have been defined by some courts under certain circumstances as attractive nuisances. As such, there may be a significant potential liability to the Owner for injury to persons on the tank and tank site, even if access is not authorized. Recent events have prompted the entire water industry to consider measures that inhibit intentional acts that could threaten the water supply. A review of the security requirements for the tank and site is recommended to confirm that the existing measures are consistent with the Owner's security requirements for their water system. Primary tank and site security should be focused on eliminating, preventing, and detecting unauthorized access to the tank. Such security measures might include routinely and periodically verifying all manholes are locked, and all exterior ladders have suitable deterrents. Other security measures might include installing a site fence topped with strands of barbed wire, no - trespassing signs, site lighting, adding motion detectors on the site, installing alarms on tank manholes, and arranging frequent site visits by law enforcement agencies. The proper operation of the existing surveillance cameras should be verified. 4. Antennas: The number and placement of the antennas, cables, and other associated equipment mounted on this tank will complicate the repainting of the tank. If left in place the 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 17 Village of Mt. Prospect, Illinois 22.129.H3 73.001 antennas, cables, and related equipment may be damaged even though steps are taken to protect the components from blasting and other work related activities. Leaving this equipment in place will also increase the cost and duration of the project. It is recommended that the antennas and antenna cables be removed prior to the work and reinstalled at the completion of the project. At a minimum, the equipment should be de -energized during work to minimize the workers exposure to radio frequencies (RF). The contract between the Owner and the antenna companies will need to be reviewed to determine if removal and de-energization is possible and who bears responsibility for the cost and liability of the equipment removal. If possible, lease requirements regarding all equipment relocation should be written in advance of all rehabilitation operations. If the equipment cannot be removed, it will need to be determined who bears the cost and liability for removing or replacing any equipment that becomes damaged during work operations. Additional considerations during work operations will also be required including worker exposures to RF emissions that may shorten workdays; how to place and construct containment to prevent fugitive dust emissions; and adequately cleaning and painting in the hard to reach areas created by the locations of this equipment. The cover on one of the column foundation shrouds should be modified to eliminate the gap between the plates. Strands of barbed wire could also be installed along the top of the chain link fence surrounding the cellular equipment located on site. 5. Foundations: When the tank exterior is repainted, any unsound concrete should be chipped to sound material and the concrete should be brush-off blasted. Any deteriorated areas or voids found should have a bonding agent and a vinyl emollient modified concrete patching mortar applied to build up the surface to its original contour. (This repair did not appear to be necessary at the time of this evaluation.) The concrete should then be painted with a concrete sealer. 6. Grout Maintenance and Sealant: All loose grout should be chipped away to solid material when the tank is empty. Any shim plates that can be removed should be taken out. Any voids in the grout should be filled with a nonshrinking, nonstaining, structural grout material. The grout should be placed as far back under the base plates as possible and squared off vertically with the edge of the base plates. (This repair did not appear to be necessary at the time of this evaluation.) Any remaining gap between the steel base plates and the grout should be filled with a flexible sealant. 7. Valve Vault: The piping and valves located in the valve vault should be cleaned and painted in accordance with the interior coating recommendations at the time of the tank cleaning and coating. The exterior concrete surfaces should be cleaned to the equivalent of a brush-off blast cleaning and painted with a concrete sealer. The valve vault access should be locked at all times in order to limit liability to the Owner and to protect water system security. Freeze protection should be provided on all control piping and static water lines. A sump and pump should be installed to eliminate the standing water. B. Exterior Tower and Container 1. Life of the Exterior Coating: The exterior coating system appeared to be providing good corrosion protection to the underlying steel. Tank Industry Consultants believes that the exterior of the container and tower surfaces should not need to be painted within the next 7 to 8 years from a corrosion standpoint. However, the exterior should be re-evaluated in 3 to 5 years, in accordance with AWWA recommendations, to determine a more precise recoating schedule. Due to the generally fair to good adhesion of the existing exterior coating, spot cleaning and topcoating the existing system may 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 18 Village of Mt. Prospect, Illinois 22.129.H3 73.001 be a viable option. The exterior coating system should be evaluated immediately prior to preparing specifications to determine if the coating adhesion is still adequate to accept a topcoat. 2. Coating Testing: Prior to preparation of specifications for the cleaning and coating of the exterior of the tank, samples of the exterior coating system should be subjected to laboratory analysis to test for ingredients which may at that time be subject to regulations concerning their handling and disposal. I Cleaning: When the exterior is to be cleaned, all varieties of containment should be investigated. Containment of the wind-blown debris and paint overspray will be required due to the proximity of the adjacent sidewalk, roads, residences, and commercial businesses. 4. Recommended Coating System: a. Spot Clean and Topcoat: If the exterior is to be repainted within the next few years, then spot cleaning and topcoating the tank appears to be the recommended option. The typical life of a spot cleaned and topcoated system is approximately 7 to 8 years, but is highly dependent on previous surface preparation and the condition of the underlying coating system. b. Coating Application: The entire exterior surfaces of the tank should be high- pressure washed to remove chalked coating, mildew, and contaminants. After washing, the damaged and rusted areas should be spot cleaned to the equivalent of an S SPC-SP 6, Commercial Blast Cleaning, or SSPC-SP 11, Power Tool Cleaning to Bare Metal. All areas of excessive coating thickness and runs in the coating should be cleaned to the equivalent of an SSPC-SP 7, Brush -Off Blast Cleaning, to remove the excessive mils. The spot cleaned areas should receive a spot prime coat compatible with the present coating system. The entire exterior surfaces should then be intermediate coated and topcoated with a compatible coating system. 5. Alternative Coating System: a. Complete Cleaning and Repainting: The most economical, long -life coating system presently available for this site is an epoxy -polyurethane coating system. Properly formulated and applied polyurethanes have good resistance to condensation, mildew, and chipping. The polyurethanes also have excellent color and gloss retention and the longest expected service life of any of the common exterior tank coatings. The typical life of a properly applied epoxy -polyurethane coating system is approximately 15 to 20 years. These coatings are also presently manufactured to meet current VOC requirements. b. Coating Application: When the tank is to be repainted, the tank should be completely cleaned and repainted. The entire tank exterior should be cleaned to the equivalent of an S SPC-SP 6, Commercial Blast Cleaning and have an epoxy -primed, epoxy intermediate and polyurethane finish coating system applied. However, care must be taken during the application of this particular coating system because this coating does have poor dry -fall characteristics, and potential damage to the surrounding property must be taken into consideration. The polyurethane coatings also require close monitoring of temperature and humidity during application. 6. Effective Service Life: Tank Industry Consultants defines the life of a coating as the amount of time before repainting becomes necessary due to coating failure and corrosion. During the 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 19 Village of Mt. Prospect, Illinois 22.129.H3 73. 001 coating life the Owner should expect the coating to lose its gloss, start to chalk, show signs of weathering, and possibly some rust staining. Future touch-up may be required on isolated coating failures. If aesthetics are a concern, the Owner may have to topcoat the repainted tank prior to the end of the expected service life. However, future topcoating would be less expensive than complete cleaning and recoating and could delay the next complete cleaning and repainting for many years. 7. Other Systems: With air emission volatile organic compounds (VOC) restrictions being put in place around the nation, alternative coating systems may become available that would be viable options for this tank. The Owner should review the available systems prior to preparing specifications for the recoating project. 8. Coating Curing: It would be more economical to paint the tank exterior at the same time the interior is painted, since the tank should be drained while the exterior is painted, and the applied coatings cure. This will also reduce mobilization and observation costs. 9. Rehabilitation Schedule: To obtain the lowest possible prices for the work outlined in the recommendations, the Owner should have the specifications prepared and the work bid in the spring, with the work scheduled to start in early summer, if possible. 10. Grinding and Bracket Removal: Any unused brackets or erection lugs should be removed prior to the exterior repainting. Any weld burrs, weld spatter, or erection scars should be ground off to provide a smooth surface for the application of the coating. This includes the hand holds and erection brackets on the columns, riser, and bowl. 11. Nameplate: The tank nameplate should be removed for the cleaning and coating of the tank. The nameplate should be cleaned and reattached to the tank using the existing bracket. 12. Electrical Apparatus: All unused electrical conduit, antennas, fixtures, electrical metering equipment, cathodic protection apparatus, and control cabinets should be removed from the tank and tank site. All required equipment should be repaired in accordance with the National Electric Code (NEC). The unused conduit should be removed from the roof. One of the conduits extending up the shell was not attached to all of its brackets, and it should be reattached. 13. Anchor Bolts: After abrasive blast cleaning, the anchor bolts, chairs, and nuts should be examined for deterioration. If deterioration is found and the anchor bolts and nuts are mild steel, the deteriorated areas of the anchor bolts should be repair welded as necessary. 14. Riser Manhole: At the time of exterior rehabilitation, the gasket for the manhole should be replaced. 15. Riser Rods, Column -to -Column Rods, Erection Brackets, and Hand Holds: The riser rods, column -to -column rods, and the hand holds and erection brackets on the columns, riser, and bowl should not be used for rigging or personnel access. 16. Exterior Ladders: The corroded and coated shell and roof ladder safe -climbing device should be verified, or it could be replaced. At the time of the exterior repainting, the safe -climbing devices should be cleaned and protected from the application of the exterior coating. The conduit should be relocated from the shell and roof side rails. 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 20 Village of Mt. Prospect, Illinois 22.129.H3 73. 001 17. Overflow Pipe: The material partial occluding the screening on the overflow pipe should be removed, or the screening could be replaced. 18. Platform: The closure chains across the existing safety railing access should be removed, and the access opening equipped with a self -closing gate as is now required by OSHA. 19. Balcony: The closure chains across the existing safety railing access should be removed, and the opening equipped with a self -closing gate. At the time of the exterior repairs and repainting, the balcony should be flooded and additional drain holes installed to adequately drain water from the balcony. The cords and flexible conduit that extended across the balcony floor should be relocated to eliminate the trip hazard. A 3-1/2 in. high curb should be installed around the overflow pipe opening in the balcony floor. 20. Clog -Resistant Vent: The proper operation of the clog -resistant vent should be periodically verified. C. Interior Surfaces Preface to Interior Recommendations: The interior surfaces below the top capacity level were evaluated by an ROV as the Owner could not drain the tank. However, the ROV evaluation was limited by the deep layer of silt located on the bowl rendering little of the bowl and none of the interior riser visible. Therefore, prior to the preparation of specifications for interior rehabilitation work, the tank should be drained, washed out and thoroughly evaluated to more accurately determine the scope of work required. A complete evaluation of the interior would also reduce the number of potential change orders, and reduce the overall amount of the bids by eliminating uncertainty about the condition of the coating and steel. 1. Life of the Interior Coating: The interior coating system appeared to be in generally good condition and, in conjunction with the cathodic protection system, providing adequate corrosion protection. The cathodic protection system should continue to be operated and maintained in accordance with manufacturer requirements. Tank Industry Consultants recommends that the interior surfaces of this tank be re-evaluated in to 3 to 5 years to determine a recoating schedule. It is recommended that when the interior is completely cleaned and repainted, an epoxy coating system should be used. 2. Coating Testing: Prior to preparation of specifications for the cleaning and coating of the interior of the tank, samples of the interior coating system should be subjected to laboratory analysis to test for ingredients that may at that time be subject to regulations concerning their handling and disposal. 3. Recommended Interior Coating System: a. Epoxy Coating System: The optimum long -life coating system presently available for the interior of water tanks is a two -component epoxy coating system. A three -coat epoxy system is recommended for the interior of this tank. This coating system should meet the certification criteria of ANSI/NSF 61 and state department of health regulations. 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 21 Village of Mt. Prospect, Illinois 22.129.H3 73. 001 b. Coating Application: When the interior is to be repainted, the entire tank interior should be cleaned to the equivalent of an SSPC-SP 10, Near -White Blast Cleaning and an epoxy coating system applied. C. Service Life: The typical life of a properly formulated and applied epoxy coating system is approximately 12 to 15 years in immersion service. Tank Industry Consultants defines the life of a coating as the expected service life before repainting becomes necessary due to coating failure and corrosion. The Owner could extend the service life of the coating by installing, properly maintaining and operating a cathodic protection system to help protect the steel surfaces in areas that have experienced coating failure. 4. Cathodic Protection: The cathodic protection system should continue to be operated and maintained in accordance with manufacturer requirements. The presence of an anode in the riser should be verified, and one should be installed if one is not found. 5. Pit Welding and Pit Filling: After initial cleaning, all significant pitting that is found should be welded, and all pitting with rough edges that would make the pitting difficult to coat properly should be filled with a solventless epoxy seam sealer. 6. Shell Stiffening Angle: The top and bottom of the interior shell angle -to -shell connection should be fully welded to the shell in accordance with AWWA D 100 recommendations. The interior shell angle should not be used for rigging purposes. 7. Rough Edges: All unused brackets should be removed from the interior and exterior surfaces at the time of the next recoating. Any weld burrs, spatter, scars or rough edges in the steel should be ground smooth to provide a better surface for coating. 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt.

Prospect Tank" Page 23 Village of Mt. Prospect, Illinois 22.129.H3 73. 001 Tank Industry Consultants has no control over the cost of labor, materials, or equipment, or over the contractors' methods of determining prices, or over competitive bidding, or the market conditions. Opinions of probable cost, as provided for herein, are to be made on the basis of our experience and qualifications and represent our best judgment as design professionals familiar with the design, maintenance, and construction of concrete and steel plate structures. However, Tank Industry Consultants cannot and does not guarantee that proposals, bids, or the construction cost will not vary from opinions of probable cost prepared for the Owner. Due to the numerous potential scopes of work that exist, the Owner should obtain an updated budget estimate once the final scope of work has been determined. This would enable the Owner to accurately budget monies for additional mobilization costs and damaged coating rehabilitation costs. Engineering and resident observation costs are not included in the Total of the Engineer's Recommendations because these fees are dependent upon the scope of work to be performed. Tank Industry Consultants performs all facets of the engineering services that would be required for this project. Estimated fees for engineering and resident observation will be furnished upon request. CLOSURE: Brief Summation: The Village of Mt. Prospect, Illinois owns and operates a 1,000,000 gallon multi - legged elevated water storage tank. Proper maintenance after completing the recommendations herein would include periodic washouts and evaluations approximately every 3 to 5 years in accordance with AWWA recommendations, and the proper operation and maintenance of the existing ice -resistant cathodic protection system with long -life anodes. Contractor Selection: The work should be performed by a competent bonded contractor, chosen from competitive bids taken on complete and concise specifications. The coatings used should be furnished by an experienced water tank coating manufacturer, supplying the field service required for application of technical coatings. Standards for Repairs and Coatings: All work and coatings applied should be in accordance with ANSI/NSF Standard 61, the coating manufacturer's recommendation, AWWA D 100, AWWA D 102, AWWA D 104/106, and specified standards of AMPP, The Association for Materials Protection and Performance (formerly SSPC: The Society for Protective Coatings and NACE International, National Association of Corrosion Engineers). Observation of Work: Observation of the work in progress by experienced personnel will offer additional assurance of quality protective coating application. Observations can be performed on a continuous basis or spot (critical phase) basis. The actual cost of observation may be less using spot as opposed to full-time resident observation; however, with spot observation it is often necessary for work to be redone to comply with the specifications. This somewhat lowers the quality of the finished product, lengthens the job, and is frequently a cause of conflict between the contractor, Owner, and field technician. Resident full-time observation minimizes the amount of "rework" required. Anniversary and Maintenance Evaluations: An anniversary evaluation should be conducted prior to the end of the one-year bonded guarantee after rehabilitation work has been completed. Washouts and 1, 000, 000 Gallon Multi -Legged, Elevated Tank, "Mt. Prospect Tank" Page 24 Village of Mt. Prospect, Illinois 22.129.H3 73. 001 coating, structural, sanitary, safety, and corrosion evaluations should be conducted not less than every 3 to 5 years. Time Frame: If the work is not performed within the next 24 months, the structure should be reevaluated prior to the preparation of specifications and solicitation of bids. Specifications and Bidding Documents: The recommendations in this report are not intended to be specifications on which a contractor can bid. Complete bidding documents must include general and special conditions, detailed technical specifications, and other information necessary for the competitive bidding process. To properly protect the interests of the Owner, Contractor, and Engineer; the initial evaluation, the technical specifications, legal portions of the contract documents, and the observation should be performed by the same firm or with close coordination of all parties involved. Limitations of Evaluation: It is believed that the conditions reported herein reflect the condition of the tank as observed on the date of the evaluation, using reasonable care in making the observations, and safety in gaining access to the tank. Should latent defects be discovered during the cleaning of the structure, they should be brought to the attention of the Owner and the Engineer. Seismic and Wind Loadings: This tank is located in or near a region of low/moderate/high seismic activity. This evaluation and the reporting of the condition of this tank do not warrant the structural condition of the tank or any of the original design for seismic loadings. Likewise, recommendations for this tank do not include modifications that may be required for compliance with present structural codes. It is possible the tank was erected in compliance with pre-existing industry standards that have since been replaced by more restrictive standards. Hazardous Materials in Coatings: It should be taken into consideration that Federal, State, and local environmental agencies have placed stricter controls on the removal of lead -based and other heavy- metal based coatings from steel structures by the use of conventional abrasive blasting techniques. The paint and blast residue may be considered to be hazardous waste depending on the concentration of lead or other particles in residue. 1, 000, 000 Gallon Multi -Legged, Elevated Tank "Mt.

Tank Industry Consultants April2026 Page 13 IN =111 VAN NUW� The Village of Mount Prospect is seeking a qualified consultant to provide engineering, design, bidding, and construction management and inspection services associated with the painting and rehabilitation of the 1,000,000 Gallon Elevated Storage Tank located at 202 East Evergreen Avenue in Mount Prospect. TIC performed the evaluation for this tank in July 2023. TIC understands that the project will include preparation of detailed construction documents, assistance during bidding, and full-time construction observation during rehabilitation activities. In addition, the Village has requested that the selected consultant perform an updated evaluation of the tank, including interior inspection utilizing both ROV and raft methods and exterior inspection, prior to finalizing the detailed technical specifications and bidding documents to confirm the current condition and refine the scope of work. TIC maintains a large and experienced field services group to support the full-time inspection requirements of the project. Based on our experience with similar elevated tank rehabilitation projects and our familiarity with the Village's water storage facilities, the anticipated scope of work will include surface preparation and coating of interior and exterior steel surfaces, along with associated structural, safety, and appurtenance improvements as identified during the evaluation. TIC's experience with elevated tank coating systems, structural components, and construction practices allows us to develop clear, project -specific specifications that address the actual condition of the tank and support efficient construction. Because TIC routinely performs both detailed evaluations and rehabilitation design, we are well positioned to incorporate the findings of the pre -bid evaluation into the development of the contract documents. This approach helps reduce uncertainty, support more competitive bidding, and promote efficient project execution. PROJECT APPROACH The following i's our detailed approach and methodology for the preparation of construction documents, bidding, construction management and resident inspection services for the Mount Prospect 1,000,000 Gallon Elevated Water Tank Painting and Rehabilitation Projeect. TIC will perform an updated evaluation of the elevated storage tank prior to preparation of final contract documents. This evaluation will include an interior inspection utilizing ROV and raft methods, as appropriate, along with a comprehensive exterior evaluation. This approach allows TIC to closely evaluate structural components such as roof framing, which is not fully visible using a single inspection method. The purpose of this evaluation is to confirm current tank conditions, identify any changes since the previous inspection, and refine the rehabilitation scope. Findings will be incorporated directly into the project specifications and cost estimate. Tank Industry Consultants April2026 Page 14 CO\ISJ ( 11 Marc0 110f, 11,J V� TIC's specifications and contract documents are project -specific and more extensive than those provided by most engineers. This level of care is enabled by our experience and extensive familiarity with the latest AWWA, NFPA, API, NACE, and SSPC standards and how they must be supplemented. Specifications are also prepared in accordance with local, state, and federal laws and all specific requirements of the Village of Mount Prospect. As TIC performed the most recent evaluation of the Village's 1,0001000-gallon elevated storage tank in July 2023, we have a well-defined understanding of R 9 U67 W Wk Em 9 M114-=.- t qk TIC's specifications are suitable for bidding. PlI10JECT CONSULTAT110N. Throughout the project design and execution, TIC's project team will be in ,iirect communication with the Village of Mount Prospect (VOMP) to ensure that the project 110 DETAILED CONSTRUCTION COST ESTIMATES. TIC provides budget estimates for construction so that the final scope of work meets the VOMP's maintenance and financial goals. After all reviews are complete, TIC revises all documents as required for final approval and prepares afinal detailed cost estimate for the project. REDUCE CONSTRUCT110N COSTS. TIC 's project -specific specifications address the actual work required for each tank, helping limit change orders to pre -defined items with competitive unit pricing. They als"t anticipate common rehabilitation challenges and incorporate cost-effective solutions that protect the ownerls interests. By addressing maintenance -prone areas during design, TIC helps extend coating system life and reduce both current and future rehabilitation costs. REPAIR AND REI 1AWILITATION DESIGN. It is important to include specific tank upgrades in the tank repainting design. TIC has found that a specification that is only end -result oriented is not adequate when working with tank repair and repainting contractors. TIC"s tank -specific repair designs provide a better finished product. Engineered solutions are vital to the successful completion of tank rehabilitation projects. COATING SYSTEM DESIGN. For elevated tank rehabilitation, TIC"s specifications address the unique requirements associated with multi -legged structures, elevated access., containment, and environmental controls. Coating systems are selected based on service environment, expected service life, and constructability, with careful consideration given to surface preparation standards, application conditions, and long-term maintenance. Some of the specific issues that are considered include: Containment Typical weather conditions during Out -of -service time application Environmental controls Compliance with regulatory agencies Access (rigging, staging) TIC does not just take a coating specification off a shelf and reuse it for every project it designs. TIC's specialty is designing unique solutions to specific project challenges.
