AE2S/Kalispell AWWTP Fermenter Rehabilitation Project
www-ae2 s.com April 28, 2021 City of Kalispell Wastewater Treatment Plant Aaron Losing WWTP Manager 2001 Airport Road Kalispell, MT 59903 Re: Experienced and Results -Focused Team to Restore Trust in Performance Coatings Dear Mr. Losing: The City of Kalispell is feeling frustrated and uncertain about the condition of its fermenter tank after identifying signs of structural concrete degradation and coating failures after only 14 years of operation. We are writing to reassure you that Kalispell is not alone. AE2S .. sees and studies this kind of concrete and metal corrosion in wastewater environments often. We are ready to guide you through the rehabilitation project you need for sustainable operations and a balanced budget. Consider these highlighted features AE2S offers for successful project delivery: ✓ A Specialized and Experienced Team to Restore Trust in Performance Coatings. The AE2S team is comprised of multi- disciplinary engineers belonging to our Odor and Corrosion Control Community of Practice dedicated to the technical skillset of performance coatings and concrete and metals restoration at water and wastewater facilities. Collectively we've seen some extreme examples of similar concrete decay and hope the results of our experiences will offer conclusive testimony to the transformations possible. With a cross-section of process and structural engineers, we will provide innovative and economical means for concrete and structural repairs to return your fermenter to service for years to come. ✓ Action -Oriented Problem Solving to Direct Project Costs to the Most Critical Activities. Ask any coatings expert the secret to a coating system's performance and they will tell you the same thing: "It's all in the surface preparation." By focusing on the fundamentals of project delivery to prioritize only the most necessary actions — defining a clear scope, the thoughtful selection of coatings systems specified, and well planned quality control provisions — the City will free up valuable project budget to spend during the most critical time — Construction. After all, during the construction phase, you often get the coating system you INSPECT, not simply the one you EXPECT. What differentiates the project we propose is less emphasis on the forensic activities during preliminary engineering, reserving more of the City's budget for the inspection and field engineering that will be required once a Contractor is ready to perform this work. ✓ Technical Experts to Allow Your Team to Focus on Big Picture Goals. We understand the City has other, more process -intensive objectives to worry about in its Facility Plan and would rather spend its time planning, building, and improving its top-notch operation. Don't let this unplanned project distract you and your current process engineers from that objective! Because our team also focuses on process treatment for other clients, we understand the operational priorities critical to most owners and will do our best to keep these anticipated problems off your desk. This level of service will allow your team to continue engaging in and working towards your bigger picture goals. We look forward to serving you and navigating the demands of this important project with our specialized knowledge of concrete repair and history of successful project delivery. Please feel free to contact us with any questions or clarifications. Our contact information is found within Section 1— General Information.

Our local resume alone demonstrates successful design and field performances. The process improvements AE2S designed in Havre for example, employ an A20 process flow configuration along with an in -line fermenter in each train for the production of volatile fatty acids (VFAs). The operational flexibility incorporated into the design of Havre's plant - in the hands of a highly skilled and innovative operator, has contributed to impressive phosphorus removal, turning heads of our statewide regulators and even making national headlines from news outlets like NPR who highlighted the innovative addition of spent grains from Havre's local brewery for increased VFA formation in the fermenter. Finally, Big Sky Co. WSD recently opened construction bids for its WRRF Improvement project designed by AE2S. The Modified Bardenpho - MBR Process aims to achieve effluent nutrient limits at the current limits of technology. But let's be clear, the problem facing Kalispell's fermenter tank is NOT a process engineering problem. PROJECT REFERENCES Intimate knowledge of BNR process design and modeling software does not intrinsically qualify our team - nor any other - to manage concrete rehabilitation projects of this nature. What does qualify the AE2S team is the work we do to foster a Community of Practice (CoP) that focuses on managing knowledge of these unique corrosion issues and delivering specialized services to Owners facing problems just like yours. Our Odor and Corrosion Control CoP is comprised of engineers from our water, wastewater, and structural practices, each with a natural curiosity and desire to address and prevent corrosion in the facilities we design. Why? Because we've seen Owners in the same situation as you - disappointed and frustrated with a coating system failure that will result in the expenditure of unplanned funds. Our Cop has built a resume of successful projects employing our specialized knowledge of and participation in professional organizations dedicated to concrete restoration and RELEVANT COMPANY EXPERIENCE (a) 0 Kalispell's Modified Johannesburg Process protective coatings. When addressing condition assessments for rehabilitation projects of this nature, our team will closely follow the industry standards adopted and recommended by these trusted organizations: • The American Concrete Institute (ACI) • The International Concrete Repair Institute (ICRI) • The Association for Materials Protection and Performance (AMPP - formed by the merger of NACE International and SSPC, the Society for Protective Coatings). Concrete repair and quality coatings applications can only be delivered through hands-on, skilled, and qualified labor under the supervision of observant and detailed field engineers closely monitoring for quality control - desk -top engineering doesn't measure up. We intend to connect the City of Kalispell to a qualified contractor you can trust to deliver an economical solution - and be there every step of the way for quality control. 11 III AE2S KALISPELL WASTEWATER TREATMENT PLANT FERMENTER REHABILITATION PROJECT STATEMENT OF QUALIFICATIONS 2.1 Bismarck, North Dakota �- WWTF BIOLOGICAL ODOR CONTROL REHABILITATION DESIGN FEE KEY PROJECT STAFF $47,300 Jayme Klecker, PE - Engineer of Record CONSTRUCTION COST Brian Viall, PE - Construction $292,000 Services Manager and Field Engineer CHANGE ORDERS Jordan Geiger - Structural 2.2% Engineer just seven years into operation of its new bio-filter, built to reduce nuisance odors from H2S collected in the pretreatment building, the City of Bismarck, ND witnessed the stark realities of concrete corrosion. The protective coating system had critically failed, exposing the cast in place concrete structure to sulfuric acid — the waste products precipitated from biofiltration of H2S gas. This exposure reduced the new concrete into a paste of gypsum (commonly known as drywall). The result left the structure with a concerning amount of exposed aggregate and rebar. Using in-depth knowledge of high-performance coating systems and concrete restoration practices, AE2S devised a strategy for rehabilitation. Specifications from the Society for Protective Coatings (SSPC), now a cooperative partner with NACE International in the Association for Materials Protection and Performance (AMPP), and the International Concrete Repair Institute (ICRI) were included in the plans and specifications. However, since examination of the majority of the rehabilitation work required removing many tons of filter media, the project required just as much evaluation, depth of knowledge, and precision engineering on the part of the field engineers during construction as it did on the design team. Close attention to detail confirmed the concrete restoration work and coating systems were applied with the highest quality control standards, all while meticulously documenting the work performed and quantities of materials used to ensure payment quantities accurately reflected the Contractor's Work Progress. The project was substantially completed ahead of schedule and periodic inspections indicate the coatings are still performing as expected. RELEVANT COMPANY EXPERIENCE O Bozeman, Montana LYMAN AND SOURDOUGH TANK CONDITION ASSESSMENT DESIGN FEE $40,000 EOPCC Lyman Phase I: $2.1 M Sourdough Phase I: $2.9 M KEY PROJECT STAFF Brian Viall, PE - Project Manager CHANGE ORDERS Study & Report Phase Current as of November 2020 The City of Bozeman hired AE2S to conduct condition assessments of two separate concrete reservoirs in service in their potable water distribution system. Sourdough Tank (a 4 MG concrete reservoir with horizontal preload wire reinforcement) and Lyman Tank (a 5 MG obelisk shaped cast -in -place concrete reservoir) are 60+ and 100+ years old, respectively. Given their age, it is understandable that both tanks are experiencing varying degrees of structural decay. The Condition Assessment included commentary on the visual inspections of concrete conditions observed at each facility. Explanations about what the visual observations might be indicative of were provided for the Owner's understanding, and additional testing methods were recommended for more detailed diagnostics. The assessment evaluates preliminary alternatives for improvements to each facility — including either A) rehabilitation or B) replacement in -kind. Detailed scopes for the engineer's approach to rehabilitation of these structures were outlined in the assessment and focused on a collaborative approach with a qualified contractor specializing in diagnostic testing methods for forensic concrete condition assessments — including destructive and non-destructive methods; concrete restoration; and high- performance protective coatings applications. Due to the usable life of these two alternatives being drastically dissimilar, the report provided a life cycle cost analysis to provide a basis upon which the City could identify the least cost alternative more confidently and appropriately budget for the capital improvements projects to come. AE25 KALISPELL WASTEWATER TREATMENT PLANT FERMENTER REHABILITATION PROJECT STATEMENT OF QUALIFICATIONS 2.2 a RELEVANT COMPANY EXPERIENCE O INTERCEPTOR CORROSION ASSESSMENT AND REHABILITATION I BROOKINGS, SOUTH DAKOTA Shortly after starting up of a new industrial user connected to the collection system, Brookings Municipal Utilities (BMU), noticed an uptick in the H2S levels in their interceptor sewer line and observed a rapid acceleration of concrete decay in the existing manholes. AE2S collected data from the structural assessments and recommended mitigation alternatives. Selecting the Most Economical Approach Seeking to address these alternatives with the most economical alternative, AE2S prepared two bid packages — each outlining a different approach to rehabilitation and corrosion protection of the 64 manholes, and let the market decide which method would be most economical. In the bid evaluation, a high performance grout and fluid applied epoxy liner system was bid against an FRP liner system — the latter proving to be most cost effective for the contractor's qualified to perform the work locally. The construction contract included extended warranty provisions that required a certified Manhole Assessment and Certification Program (MRCP) inspection of the manhole liner system 18-24 months after substantial completion to confirm performance of the installed manhole liner system. This project was featured in the Water Environment Federation's October 2017 WWTF INFLUENT WET WELL REHABILITATION I HAVRE, MONTANA The influent wet well at Havre's W WTP is original to the 1940s construction, and access is limited such that investigation during design of the City's overall plant upgrade was not practical. When construction sequencing for the plant upgrades finally allowed closer examination, the condition assessment showed that the concrete degradation was severe and a significant rehabilitation was necessary. In cooperation with the contractor, AE2S developed a Maintenance of Plant Operations (MOPO) plan to use bypass pumps to direct influent flow from the headworks to secondary treatment. The approach to rehabilitation focused on proper surface preparation. It started with sandblasting to remove the loose and decayed concrete; application of a bonding/sealing agent on the concrete and structural rebar; placement of cementitious and aggregate reinforced concrete resurfacers to fill voids and establish the appropriate concrete surface profile required for proper application of a corrosion resistant and protective epoxy based top coat. The concrete/rebar degradation was extensive and structural integrity was added with cast -in -place reinforcement "beams" Throughout the restoration process, AE2S provided construction inspection to verify the contractor's application methods met manufacturers' recommendations and met industry standards. To date, the Havre WWTF staff continue to perform coatings checks on an annual basis. With over five years in service, WWTF INTERIM OPTIMIZATION I MANDAN, NORTH DAKOTA The City of Mandan has long since struggled with high H2S concentrations in their pretreatment building. By 2013, the volume and concentrations had overwhelmed the existing odor control system which was beyond its usable life. Additionally, with an influx of population, the facility began to receive a significant number of nuisance odor complaints from the encroaching developments and homeowners, and the City had to respond. AE2S was given the nod to proceed with design and construction of an odor control bio-filter. The project included a new odor control facility, complete with an air scrubber and a bio-filtration basin. The concrete basin housing the bio- filter media was scheduled to receive a high-performance protective coating as a barrier against the biproducts of biological filtration which have low pH values and quickly decay concrete. Additionally, the design included a restoration and reapplication of protective coatings on the walls of the headworks building. During construction, the Engineer and RPR worked diligently with the certified coatings applicator for quality control. Coating systems were reviewed in detail against the project specifications and the team held regular pre -application coatings meetings on -site to ensure surface preparation, application, and curing methods conformed to specified performance standards and manufacturers' recommendations. The coating system inspection was closely observed and reviewed to verify holidays (pinholes in the coating layer) and other field quality control issues common with coatings applications were identified and remedied properly prior to the Owner's acceptance and a Edition of WE&T entitled "Characterization of Hydrogen -Sulfide -Induced Concrete Corrosion Using Established and New Methods". 0 DESIGN FEE $40,000 CONSTRUCTION COST $427,822 KEY PROJECT STAFF Scott Schaefer, PE - Engineer of Record Jordan Geiger- Structural Engineer CHANGE ORDERS -3.2% 0 the influent wet well rehabilitation is in excellent condition with no signs of coatings degradation.

AE2S KALISPELL WASTEWATER TREATMENT PLANT FERMENTER REHABILITATION PROJECT STATEMENT OF QUALIFICATIONS 31 0 CONTRACT UNDERSTANDING AND APPROACH (D 4 � CONTRACT UNDERSTANDING AND APPROACH The City of Kalispell has three primary concerns with their fermenter's existing conditions: 1) the concrete condition; 2) the structural integrity of the facility itself; and 3) the condition of the existing process equipment. After only 14 years of service, these may seem like premature signs of facility failure, but considering the environment in which the equipment operates and the extent to which it ever received a protective coating in the first place, this proposed scope of rehabilitation efforts seems to be a relatively common (though inconvenient) maintenance cost. In fad, given the above, these concerns are neither a surprise to AE2S' project team, but more importantly, nor do they seem insurmountable - especially when measured against our past experience. We understand it is tempting to want to identify the exact cause of the coating failure in an attempt to not repeat the same mistakes; however, that job is better left to material scientists as the endless variables and much scientific analysis required to obtain a definitive answer is assuredly beyond the City's budget. Further, this information will not significantly influence the means and methods a coatings applicator will want to use for concrete repair of this nature - we know, because we've asked. Our experience addressing these concerns for Owner's of past rehabilitation projects has taught us to ask the appropriate questions and identify solutions that keep the Owner's best interests at heart: How do we preserve as much of the remaining usable life as possible? What is different about our team's approach to delivering the `Required ® Concrete Conditions After some initial investigation and collaboration with the City, we anticipate developing construction plans to define the scope and anticipated extent of concrete repair as clearly as possible. We will specify products suitable for the environment's exposure and with a record of success. Many of these manufacturers offer certification G Structural Integrity We understand the City's concern over structural stability of the remaining structure. It is certainly alarming to see exposed aggregate and signs of corroded Services" outlined in the RFQcomes down to the framework of project delivery methods. We recommend following: the classic design -bid -build method. We propose requiring the contractor to perform these services during the contruction phase of the project. These tests are more suited to serve as a means of verifying their own surface preparation work immediately prior to applications of a coating. Taking tests for potential contaminants during preliminary engineering seem frivolous as existing surface contaminants would assuredly be removed by abrasive sandblasting during construction, revealing an entirely different surface profile . likely cleaned of contaminants. Further, it is highly unlikely that chlorides are to blame for the corrosion observed. Chlorides are a notoriously recalcitrant constituent of wastewater, so the chlorides concentration in the fermenter should be similar to that of the downstream process basins - where little to no corrosion is being noted or observed. In the anaerobic conditions of the fermenter, it is more likely that sulfides and other inorganic elements from either the fermentation process or microbial respiratory action are to blame for the superficial decay and erosion. Such was the case in the photos at the right where sulfuric acid at pH's around 1.0 eroded literally inches of concrete depth away from this five -year -old concrete structure. After sandblasting and concrete repair, the concrete was completely resurfaced and free of contaminants, ready to receive its protective coatings. Six years from substantial completion, these coatings are still performing as expected. programs to qualify contractors. Our bid dots will ask applicator-contrators to provide proof of certification as one level of quality assurance for appropriate systems. To aid in the clarity of these plans, we have added Mongan Painting to our project team. Matt Mongan is the owner and foreman of the painting company employed rebar, especially in a tank structure tasked with containing thousands of gallons of liquid at depths up to 27 feet. However, based on review of the photos contained on the Bismarck Biofilter Rehab project. His demonstrated expertise in the application of performance coatings and concrete restorations will be a valuable addition to the project. The progression of photos above, demonstrates the kind of total transformations possible with this approach under the design and management of the AE2S Team. in the Condition Assessment Tech Memo, the concrete decay appears to be mostly superficial. Additionally, it is difficult to say whether the signs of corrosion and AE2S KALISPELL WASTEWATER TREATMENT PLANT FERMENTER REHABILITATION PROJECT STATEMENT OF QUALIFICATIONS 41 exposure of the rebar are due to extreme corrosion or simply a quality control issue during construction. Circular cast -in -place concrete tanks are a challenge for the most experienced of builders. It is possible that the isolated locations of corroded rebar never had the intended depth of cover from the day the concrete was placed. To evaluate this further, a reinforcing steel cover survey can be easily achieved as a non-destructive form of testing using ground penetrative radar. Further, ACI 562-16 has recommendations to clean and prepare exposed rebar for continued service. These CONTRACT UNDERSTANDING AND APPROACH (�) are the same methods used to protect the exposed rebar discovered in the structure pictured on the previous page. Additionally, we are confident in a number of alternatives that can be used to reinforce the structural integrity of the facility and extend the fermenter's usable life. Further, these will be much better solutions than to complete a replacement in -kind. To name a few alternatives, companies like Vector Construction can apply carbon - fiber reinforced "wraps" to the exterior walls of the structure for added rigidity and reinforcement. Alternatively, contractors 0 Existing Process Equipment Finally, the process equipment's protective coatings have obviously reached the end of their usable life. However, 17 years of submerged service is approaching the expected reasonable limit. Again, this rehabilitation is nothing that isn't to be expected. Much like corroded concrete, our team is no stranger to managing the challenges posed during construction of even the most routine of coating applications. After sandblasting the clarifier structure of Mandan, ND's sedimentation basin, a sThe Best Defense is a Good Offense A coatings restoration and concrete repair project will inevitably present similar field challenges to the handful discussed in this section.

AE2S KALISPELL WASTEWATER TREATMENT PLANT FERMENTER REHABILITATION PROJECT STATEMENT OF QUALIFICATIONS 4.2 APPROACH TO CONTRACT MANAGEMENT O 5 0 APPROACH TO CONTRACT MANAGEMENT 0 The Team Project Team with Proven Experience Understanding the project context and goals are imperative when developing a project team that is ready to address the key challenges in the most innovative, reliable, and cost effective manner. The team we've organized for this project - the relationships in which are summarized in the organizational chart presented here - is filled with the experience and qualifications desired for successful delivery and lasting success. 0 Creating a Vision and Setting Goals for Successful Delivery A Tested Framework for Project Success It is common for the typical public works construction project to follow the project delivery methods outlined in The Montana Contractors Association's(MCA) Montana Public Works Standard Specifications (MPWSS). This document is useful for the routine improvements to underground utilities, with a focus on the typical construction Divisions such as Site Work and Concrete. It is a highly reusable document for projects of similar and recurring scope (like compaction requirements and manhole details) and adds efficiency to the construction administrator's work. In contrast, the reality of your fermenter's needs - the skilled application of high performance protective coatings - is anything but typical. This scope inherently carries a different level of risk and performance requirements that should be balanced. Further, the most current version of the MPWSS relies on Construction Series Contract Documents from 2007. A lot has changed in the construction industry and construction case law since 2007 to necessitate updates to the General Conditions and all other Bidding Documents, Contract Documents, and Project Forms. Indeed the MCA is in the process of updating the MPWSS around the 2018 version of EJCDC's Construction Series Documents. This update is anticipated in May 2021. Your PM, Brian Viall, is familiar with project delivery using the 2018 Edition of the MPWSS, having delivered projects for Owner's in Montana with these 2018 Construction Series Documents successfully. Further, for the specialty construction of what we call "vertical infrastructure" we feel the Owner's who've adopted these Contract Documents have the most project success. Independent Third Party Inspections AE2S serves our clients with our strengths: Engineering and Project Delivery. We intentionally follow the EJCDC's traditional method of project delivery which prioritizes the Owner's risk by placing testing and specialized inspection services on an independent third party. In a rural geography like Montana, it is best to leave these inspections to the independent testing firms like ST&I who have highly trained inspectors that perform the volume of tests required to stay current and relevant in the field. Though we have a deep understanding of proper and appropriate coatings applications, we feel an independent inspector will provide the City with the most peace of mind and validate the product if any conflict between your Engineer and contractor should arise. Our priority will be connecting you to these qualified organizations in a meaningful and efficient manner. Qualifications of Bidders Through our connections to coatings applicators (like Mongan Painting Company) and coatings manufacturers (like TNEMEC) and the use of EJCDC's Bidder's Qualifications Statement, we will expect applicator/contractors to be certified by the product manufacturer's specified. This will build a relationship of trust between the Owner and their contractor.
