Dispute Resolution. Client shall not be entitled to assert a Claim against Consultant based on any theory of professional negligence unless and until Client has obtained the written opinion from a registered, independent, and reputable engineer, architect, or geologist that Consultant has violated the standard of care applicable to Consultant's performance of the Services. Client shall provide this opinion to Consultant and the parties shall endeavor to resolve the dispute within 30 days, after which Client may pursue Its remedies at law. This Agreement shall be governed by and construed according to Kansas law. 12. Subsurface Explorations. Subsurface conditions throughout the site may vary from those depicted on logs of discrete borings, test pits, or other exploratory services. Client understands Consultant's layout of boring and test locations is approximate and that Consultant may deviate a reasonable distance from those locations. Consultant will take reasonable precautions to reduce damage to the site when performing Services; however, Client accepts that invasive services such as drilling or sampling may damage or alter the site. Site restoration Is not provided unless specifically Included in the Services. 13. Testing and Observations. Client understands that testing and observation are discrete sampling procedures, and that such procedures indicate conditions only at the depths, locations, and times the procedures were performed. Consultant will provide test results and opinions based on tests and field observations only for the work tested. Client understands that testing and observation are not continuous or exhaustive, and are conducted to reduce - not eliminate - project risk. Client shall cause all tests and inspections of the site, materials, and Services performed by Consultant to be timely and properly scheduled in order for the Services to be performed In accordance with the plans, specifications, contract documents, and Consultant's recommendations. No claims for loss or damage or Injury shall be brought against Consultant by Client or any third party unless all tests and Inspections have been so performed and Consultants recommendations have been followed. Unless otherwise stated in the Proposal, Client assumes sole responsibility for determining whether the quantity and the nature of Services ordered by CI'ent is adequate and sufficient for Client's intended purpose. Client Is responsible (even If delegated to contractor) for requesting services, and notifying and scheduling Consultant so Consultant can perform these Services. Consultant Is not responsible for damages caused by Services not performed due to a failure to request or schedule Consultant's Services. Consultant shall not be responsible for the quality and completeness of Client's contractor's work or their adherence to the project documents, and Consultant's performance of testing and observation services shall not relieve Client's contractor in any way from its responsibility for defects discovered in its work, or create a warranty or guarantee. Consultant will not supervise or direct the work performed by Client's contractor or its subcontractors and is not responsible for their means and methods. The extension of unit prices with quantities to establish a total estimated cost does not guarantee a maximum cost to complete the Services. The quantities, when given, are estimates based on contract documents and schedules made available at the time of the Proposal. Since schedule, performance, production, and charges are directed and/or controlled by others, any quantity extensions must be considered as estimated and not a guarantee of maximum cost. 14. Sample Disposition, Affected Materials, and Indemnity. Samples are consumed in testing or disposed of upon completion of the testing procedures (unless stated otherwise in the Services). Client shall furnish or cause to be furnished to Consultant all documents and information known or available to Client that relate to the identity, location, quantity, nature, or characteristic of any hazardous waste, toxic, radioactive, or contaminated materials ("Affected Materials") at or near the site, and shall immediately transmit new, updated, or revised Information as it becomes available. Client agrees that Consultant is not responsible for the disposition of Affected Materials unless specifically provided in the Services, and that Client Is responsible for directing such disposition. In no event shall Consultant be required to sign a hazardous waste manifest or take title to any Affected Materials. Client shall have the obligation to make all spill or release notifications to appropriate governmental agencies. The Client agrees that Consultant neither created nor contributed to the creation or existence of any Affected Materials conditions at the site and Consultant shall not be responsible for any claims, losses, or damages allegedly arising out of Consultants performance of Services hereunder, or for any claims against Consultant as a generator, disposer, or arranger of Affected Materials under federal, state, or local law or ordinance. 15. Ownership of Documents. Work product, such as reports, logs, data, notes, or calculations, prepared by Consultant shall remain Consultants property.

These services are described in the following sections. Field Exploration Claassen Engineering & Surveying, Inc. requested the following boring scope of services: Number of Borings Planned Boring Depth (feet) Planned Location Lift Station 1 50 or practical auger/bit refusal 1. Below the existing ground surface Boring Layout and Elevations: Claassen Engineering & Surveying personnel will stake the boring location and provide the ground surface elevation to Terracon. Subsurface Exploration Procedures: We will advance the boring with a rotary drill rig using continuous flight augers and mud -rotary drilling methods. Sampling will be performed using a split barrel sampler or thin -walled tubes at intervals of 2.5 feet in the upper 20 feet and at intervals of 5 feet thereafter. In the thin -walled tube sampling procedure, a thin -walled, seamless steel tube with a .sharp cutting edge is pushed hydraulically into the soil to obtain a relatively undisturbed sample. In the split -barrel sampling procedure, a standard 2-inch outer diameter split -barrel sampling spoon is driven into the ground by a 140-pound automatic hammer falling a distance of 30 inches. The number of blows required to advance the sampling spoon the last 12 inches of a normal 18-inch penetration is recorded as the Standard Penetration Test (SPT) resistance value. The SPT values, also referred to as N-values, are indicated on the boring logs at the test interval depths. The boring will terminate at practical auger refusal, if encountered. We observe and record groundwater levels during and after drilling and sampling. In some instances, groundwater observations may not be made because drilling fluid or water are used for drilling and/or rock coring, which makes groundwater level observations during and after drilling potentially unrepresentative. Terracon's exploration team prepares a field boring log as part of standard drilling operations. The field log includes sampling interval depths, penetration resistances, and other relevant drilling and sampling information. Our field log also includes visual descriptions of materials encountered during drilling and the drill crew's interpretation of subsurface conditions between samples. The samples are placed in appropriate containers and transported to our laboratory for further testing and classification. Responsive ® Resourceful n Reliable EXHIBIT B. SCOPE OF SERVICES 1 of 5 Proposal for Geotechnical Engineering Services North Hackett Lift Station ® Waterloo, Iowa August 7, 2017 a Terracon Proposal No, P13175103 1rerracon Our engineering staff and the drill crew communicate during the exploration. If the soil conditions encountered appear to be unfavorable or marginal, we may modify our subsurface exploration while we are on site. If additional fees apply, we contact the client for authorization, prior to performing any additional services. Site Access and Property Disturbance: We considered that the site and boring location can be accessed using our drilling equipment. Terracon personnel will take reasonable measures to limit the amount of damage to the property. However, some damage to pavements, rutting of the ground surface, and/or damage to landscape could occur. Therefore, it is important that Terracon be granted access to the site (or legal right of entry) by the property owner. Please notify Terracon if arrangements have not been made for subsurface exploration on the property. Please also note that our scope of services does not include clearing or grubbing, wet ground conditions, or repair of/damage to existing landscape. If such services are desired by the owner/client, we should be notified so we can adjust our scope of services. We backfill our boreholes with auger cuttings and/or bentonite chips after completion. Our services do not include repair of the site beyond backfilling our boreholes. Excess auger cuttings are dispersed in the general vicinity of the borehole. Because backfill material often settles below the surface after a period, we recommend boreholes be checked periodically, and backfilled if necessary. We can provide this service, or grout the borehole for an additional fee, at your request. Laboratory Testing The project engineer reviews field data and assigns laboratory tests to better understand the engineering properties of various soil and rock strata. The actual types and number of tests cannot be defined until completion of field work. Procedural standards noted below are for reference to methodology in general. In some cases, local practices and professional judgement require method variations. Standards noted below include reference to other related standards. Such references are not necessarily applicable to describe the specific test performed. ▪ ASTM D2216 Standard Test Methods for Laboratory Determination of Water (Moisture) Content of Soil and Rock by Mass • ASTM D4318 Standard Test Methods for Liquid Limit, Plastic Limit, and Plasticity Index of Soils ® ASTM D422 Standard Test Method for Particle -Size Analysis of Soils ® ASTM D2166/D2166M Standard Test Method for Unconfined Compressive Strength of Cohesive Soil • ASTM D2974 Standard Test Methods for Moisture, Ash, and Organic Matter of Peat and other Organic Soils Responsive ® Resourceful ® Reliable EXHIBIT B • SCOPE OF SERVICES 2 of 5 Proposal for Geotechnical Engineering Services North Hackett Lift Station ® Waterloo, Iowa August 7, 2017 ® Terracon Proposal No. P13175103 1 Ferracon Our laboratory testing program includes observation of recovered soil samples by an engineer and/or a geologist. Based on the texture and plasticity of the soil, we describe and classify samples in general accordance with the Unified Soil Classification System (USCS). Recovered bedrock samples are visually and tactilely classified using locally accepted practices for engineering purposes. Petrographic analysis (if performed) may reveal other rock types. Rock core samples typically provide an improved specimen for this classification. Samples recovered during the subsurface exploration would be retained in our office for a period of 60 days after submittal of our geotechnical engineering report in the event that additional testing is requested. Safety Terracon is currently not aware of environmental concerns at this project site that would create health or safety hazards associated with our field exploration program. Thus, the estimated fee includes our exploration team using standard Personal Protection Equipment (PPE) for geotechnical drilling including hard hats, safety glasses, hearing protection, high visibility vests, and steel -toed boots. Our scope of services does not include environmental site assessment services, but identification of unusual or unnatural materials encountered while drilling and/or sampling will be noted on our logs and discussed in our report. Terracon notifies Iowa One Call to request location and marking of public utilities at least 48 hours prior to performing borings/excavations. We consult with the owner/client regarding potential private utilities, or other underground hazards. Based on the results of this consultation, we consider the need for alternative subsurface exploration methods, as the safety of our exploration team members is a priority. Private utilities should be marked by the owner/client prior to commencement of subsurface exploration. Terracon will not be responsible for damage to utilities that are incorrectly marked or not made aware to us. If the owner/client is not able to accurately locate private utilities, Terracon can assist the owner/client by coordinating or subcontracting with a private utility locating service. Fees associated with location and marking of private utilities are considered additional services and are not included in our current scope of services. The estimated fee for the location and marking of private utilities will be forwarded to our client for approval. The detection of underground utilities is dependent upon the composition and construction of the utility line; some utilities are comprised of non -electrically conductive materials and may not be readily detected. The use of a private utility locate service would not relieve the owner of their responsibilities in identifying private underground utilities.

The engineer develops a geotechnical site characterization, performs the engineering calculations necessary to evaluate foundation alternatives, and develops appropriate geotechnical engineering design criteria for earth -related portions of the project. Your project will be delivered using our GeoReport system. Upon initiation, we will provide you and your design team the necessary link and password to access the website (if not previously registered). Each project includes a calendar to track the schedule, an interactive site map, a listing of team members, access to all project documents as they are uploaded to the site, and a collaboration portal. A typical delivery process includes three basic stages: a Stage 1: Project Planning a Stage 2: Site Characterization ® Stage 3: Geotechnical Engineering When utilized, a collaboration portal documents communication, eliminating the need for long email threads. This collaborative effort allows prompt evaluation and discussion of options related to the design and associated benefits and risks of each option. With the ability to inform all parties as the work progresses, decisions and consensus can be reached faster. In some cases, only minimal uploads and collaboration will be required, because options for design and construction are limited or unnecessary. This is typically the case for uncomplicated projects with no anomalies found at the site. When our geotechnical engineering report is complete, we will upload a printable version of our report, including the professional engineer's seal and signature, which documents our services. Previous submittals, collaboration, and final report will be maintained in our system, which allows future reference and integration into subsequent aspects of our services, as the project goes through final design and construction.

Two geotechnical engineering reports will be prepared for the project. One report will be prepared for the railroad right-of-way crossings and one report will be prepared for the sanitary sewer and road reconstruction. The purpose of our services for the railroad crossings will be to characterize the subsurface conditions based on the borings performed in the pit areas and provide the information in a geotechnical engineering report to be included in the initial notification submittal to CN. Our scope of services considers that the launching and receiving pits, and hence the borings, will be located outside of the CN railroad 'zone of influence' and right-of-way, and shoring designs will not be required in the 'initial notification of intent to construct a utility crossing/encroachment' submittal to CN. Our geotechnical engineering report will be referenced by contractors bidding on the project to select their method of installation, and to develop their pit/excavation and dewatering designs and construction monitoring program. The project's bid documents will need to include a detailed performance specification for the contractor(s). The purpose of our services for the pavements and underground utilities will be to characterize the subsurface conditions based on the borings performed and provide pavement thickness designs for Westfield Avenue and Duryea Street. General earthwork recommendations and general construction considerations for earthwork and utility excavations will also be provided. Terracon's earthwork recommendations and construction considerations will be used by WCES to develop project bid documents and specifications for the project. Field Services Boring Locations and Elevations: Terracon will provide a proposed boring plan to WCES and the City of Waterloo for consideration after authorization to proceed is received and further communications regarding existing and proposed construction. We recommend WCES stake the boring locations and provide surface elevations and latitudes and longitudes of the boring locations to Terracon. Terracon will use a handheld GPS unit in the field to determine the latitude and longitude of the boring locations. Our GPS equipment has a minimum horizontal accuracy of about 20 feet. The locations and elevations of the borings should be considered accurate only to the degree implied by the methods used to define them. Safety and Underground Utility Locations: Terracon is currently not aware of environmental concerns at this project site that would create health or safety hazards associated with our field services. Thus, the estimated fee includes our exploration team using standard Personal Protection Equipment (PPE) for geotechnical drilling including hard hats, safety glasses, hearing protection, high visibility vests, and steel -toed boots. Our scope of services does not include environmental site assessment services, but identification of unusual or unnatural materials Responsive ® Resourceful ® Reliable EXHIBIT B - SCOPE OF SERVICES 1 of 6 Proposal for Geotechnical Engineering Services NW Interceptor Sewer a Waterloo, Iowa December 23, 2019 n Terracon Proposal No. P13195135 ir rrac encountered while drilling and/or sampling will be noted on our logs and discussed in our report. If impacted soil/material is encountered in a boring, the boring will be terminated and our findings discussed with the client prior to further drilling at the location. Upon completion of staking and surveying by WCES, Terracon will notify Iowa One Call to request a 'joint meeting' for subsequent location and marking of public utilities, at least 48 hours prior to performing borings/excavations. We will consult with the owner/client regarding potential private utilities, or other underground hazards. Based on the results of this consultation, Terracon will consider the need for alternative subsurface exploration methods; as the safety of our exploration team members and avoiding damage to existing improvements are priorities. Any private utilities should be marked by the client or owner prior to subsurface exploration. Terracon will not be responsible for damage to utilities that are incorrectly marked or not made aware to us. If the client is not able to accurately locate private utilities, Terracon can assist the client by coordinating or subcontracting with a private utility locating service. Please note that our scope of services and fee does not include the location and marking of private utilities. Subsurface Exploration: Terracon has performed borings on Westfield Avenue from Ansborough Avenue to Fletcher Avenue. WCES has indicated that the existing boring information will be used for this project and no borings are requested from Ansborough Avenue to Fletcher Avenue. Terracon's subsurface exploration program includes performing a soil boring in the area of each pit for the utilities planned, as required by CN. We also propose performing borings at intervals of about 300 feet along Westfield Avenue from Fletcher Avenue to Duryea Street and along Duryea Street from Westfield Avenue to Falls Avenue. Per the request of WCES, rock coring is not included in the scope of services. Therefore, if practical auger refusal is experienced in bedrock, the borings will be terminated. The following boring program is proposed. of umbersz< Bonngs s n Planned ' Boring (feet) Depth Planned Area 4 40 Rail Crossings/ Bore Pits 13 20 or auger refusal Sanitary Sewer 6 2 20 or auger refusal Sanitary Sewer 1.

Sampling will be performed using a split barrel sampler or thin -walled tubes at intervals of 2.5 feet in the upper 20 feet of each boring and at intervals of 5 feet thereafter. As mentioned previously, if practical auger refusal is experienced in bedrock, in borings performed for the sanity sewer, the borings will be terminated. Upon encountering bedrock or practical auger/bit refusal in the pit borings, coring of bedrock using a double -wall, NQ/NX core barrel will be performed to a depth of at least 5 feet greater than the planned maximum invert depth of the sanitary sewer. Rock coring/sampling is performed continuously; however, rock core recovery is partially dependent on the quality, consistency, or degree of cementation of the rock. Water will be used for rock coring and the spent water/fluid will be discharged on -site, unless we are directed otherwise. Terracon's exploration team will observe and record groundwater levels during and after drilling and sampling. In some instances, groundwater observations may not be representative because drilling fluids or water are used. Open boreholes will be covered between the time the boring is completed and backfilled. Terracon's exploration team prepares field logs as part of standard drilling operations. The field logs include sampling interval depths, sample recoveries, penetration resistances, and other relevant drilling and sampling information. Our field logs also include visual descriptions of materials encountered during drilling and the drill crew's interpretation of subsurface conditions between samples. The samples are containerized and transported to our laboratory for further testing and classification. Our engineering staff and the drill crew communicate during the exploration. If the subsurface conditions encountered appear to be unfavorable or marginal, we modify our subsurface exploration while we are on site. If additional fees apply, we contact the client for authorization, prior to performing any additional services. Site Access and Property Disturbance: We considered that the boring locations (and pits) will be located outside of the CN right-of-way, and railroad permits and flagmen will not be required. We anticipate performing the borings through the existing roadways. We also considered that traffic control, consisting of signs and flagmen to allow one lane of the roadway to remain open, will be required for the borings performed in Westfield Avenue. Signs will be used to notify motorists of work in the right-of-way. We also considered that the sites and boring locations can be accessed using our ATV -mounted drill rig without the assistance of other machinery. Terracon personnel will take reasonable measures to limit the amount of damage to the properties. However, some damage to pavements, rutting of the ground surface, and/or damage to landscape could occur. Please note that our scope of services and fee do not include services associated with site clearing, soft/wet ground conditions, or reparations to damage of the existing Responsive a Resourceful a Reliable EXHIBIT B - SCOPE OF SERVICES 3 of 6 Proposal for Geotechnical Engineering Services NW Interceptor Sewer o Waterloo, Iowa December 23, 2019 Terracon Proposal No. P13195135 lieu atc n landscape. If such services are desired, we should be notified so we can adjust our scope of services. It is important that Terracon be granted access to the sites (i.e., legal right -of -entry) by the property owners. Please notify Terracon if arrangements have not been made for subsurface exploration on the properties. At least 7 days of notice will be provided to WCES and The City of Waterloo of our intent to notify Iowa One Call and perform the field exploration. Pit boreholes will be backfilled with portland cement-bentonite grout after completion. All other boreholes performed for the sanitary sewer and road reconstruction will be backfilled with auger cuttings and bentonite chips. Pavements will be patched with commercially -available, high early strength concrete or cold patch asphalt. Our services do not include repair of the sites beyond backfilling our boreholes and patching of pavements. Any excess auger cuttings will be disposed of in an area designated by authorized personnel. Because backfill material often settles below the surface after a period, we recommend boreholes be checked periodically, and backfilled if necessary. Terracon can provide this service for an additional fee, upon request. Long-term maintenance of the boreholes will be the responsibility of the client. Laboratory Testing Our laboratory testing program includes observation of recovered soil samples by an engineer and/or a geologist. Based on the texture and plasticity of the soil, we describe and classify soil samples in general accordance with the Unified Soil Classification System (USCS). The project engineer reviews field data and visual classifications and assigns laboratory tests for engineering evaluations. Laboratory testing planned for this project is presented in Exhibit C and includes water content, particle size analyses, dry density, unconfined compression, organic content, plastic and liquid limits, and pH tests. Laboratory testing of recovered bedrock core samples will include compressive strength of intact rock core samples. Recover bedrock samples will be visual and tactile classification using locally accepted practices for engineering purposes. Petrographic analysis (if performed) may reveal other rock types. Rock core samples typically provide an improved specimen for rock classification. Samples recovered during the subsurface exploration will be retained in our office for a period of 90 days after submittal of our geotechnical engineering report.
