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 Iowa 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 Consultant's 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 Client 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 Consultant's property. Proprietary concepts, systems, and ideas developed during performance of the Services shall remain the sole property of Consultant. Files shall be maintained in general accordance with Consultant's document retention policies and practices. 16. Utilities. Unless otherwise stated in the Proposal, Client shall provide the location and/or arrange for the marking of private utilities and subterranean structures. Consultant shall take reasonable precautions to avoid damage or injury to subterranean structures or utilities. Consultant shall not be responsible for damage to subterranean structures or utilities that are not called to Consultant's attention, are not correctly marked, including by a utility locate service, or are incorrectly shown on the plans furnished to Consultant. 17. Site Access and Safety. Client shall secure all necessary site related approvals, permits, licenses, and consents necessary to commence and complete the Services and will execute any necessary site access agreement. Consultant will be responsible for supervision and site safety measures for its own employees, but shall not be responsible for the supervision or health and safety precautions for any other parties, including Client, Client's contractors, subcontractors, or other parties present at the site. In addition, Consultant retains the right to stop work without penalty at any time Consultant believes it is in the best interests of Consultant's employees or subcontractors to do so in order to reduce the risk of exposure to the coronavirus. Client agrees it will respond quickly to all requests for information made by Consultant related to Consultant's pre -task planning and risk assessment processes. Client acknowledges its responsibility for notifying Consultant of any circumstances that present a risk of exposure to the coronavirus or individuals who have tested positive for COVID-19 or are self -quarantining due to exhibiting symptoms associated with the coronavirus.

Aspects of the project, undefined or assumed, are highlighted. We request the design team verify all information prior to our initiation of field exploration activities. Site Location and Anticipated Conditions Item Description Site Location Existing Improvements Existing Topography Site Access Expected Subsurface Conditions The project site is located at the intersection of Highway 21 and E. Orange Road in Waterloo, Iowa. Latitude: 42.4283, Longitude: -92.3470 (See Exhibit D) Asphaltic pavements with gravel shoulders, ditches, and overhead electric lines are present. Based on publicly available USGS 24k topographic maps, site elevations rise from an elevation of about 910 feet near the south end of the utility alignment to an elevation of about 935 feet at the intersection of Highway 21 and E. Orange Road. The utility alignment is relatively flat along Orange Road. We expect the site, and all exploration locations, can be accessed using our atv-mounted drilling equipment without the assistance of other heavy machinery. Our experience in the vicinity of the project site indicates subsurface conditions consist of several feet of fill over glacial clay soils. Granular soils may be present near the creeks and drainageways. Planned Construction Item Description General Project Description Sanitary sewer extensions are planned about 2,200 feet to the south and about 1,600 feet west of the intersection of Highway 21 and E. Orange Road. The sewer inverts are planned to be as much as 15 feet below existing grades. Responsive • Resourceful • Reliable EXHIBIT A - PROJECT UNDERSTANDING 1 of 1 Proposal for Geotechnical Engineering Services Sanitary Sewer Expansion Waterloo, Iowa July 22, 2022 Terracon Proposal No. P13225059 EXHIBIT B - SCOPE OF SERVICES lrerracon Our proposed Scope of Services consists of field exploration, laboratory testing, and engineering/project delivery. These services are described in the following sections. Field Exploration The City of Waterloo requested the following boring locations and depths: Number of Borings Planned Boring Depth (feet)' Planned Location 7 20 or auger refusal Below ground surface. Sanitary Sewer Route Boring Layout and Elevations: Terracon will determine the boring locations and stake the locations in the field. Latitudes and longitudes will be obtained by superimposing the site plan onto Google Earth photography. We will used handheld GPS equipment to locate the borings in the field. Our GPS equipment has a minimum horizontal accuracy of about 20 feet. Approximate elevations will be obtained by plotting the borings on the IDNR Lidar Elevation Tool. The locations and elevations of the borings should be considered accurate only to the degree implied by these methods. If more accurate boring locations and elevations are desired, we suggest a land surveying firm stake the boring locations and provide surface elevations at the boring locations to us. Subsurface Exploration Procedures: We will advance the borings with a rotary drill rig using continuous flight augers. Sampling will be performed using a split -barrel sampler or thin -walled tubes at intervals of 2.5 feet in the upper 15 feet of each boring. We observe and record groundwater levels during and after drilling and sampling. Open boreholes will be covered between the time the boring is completed and backfilled. Terracon's exploration team prepares field boring logs as part of standard drilling operations. The field logs include sampling interval depths, 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 placed in appropriate containers and transported to our laboratory for further testing and classification. Our engineering staff and the drill crew communicate during the exploration. If the soil 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. Responsive • Resourceful • Reliable EXHIBIT B - SCOPE OF SERVICES 1 of 4 Proposal for Geotechnical Engineering Services Sanitary Sewer Expansion Waterloo, Iowa July 22, 2022 Terracon Proposal No. P13225059 lrerracon Safety: Terracon is currently not aware of environmental concerns at this project site that would create health or safety hazards associated with our subsurface 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. For the purpose of preparing our cost estimate, we considered that a right-of-way permit will be not be required by the City of Waterloo. Traffic control including signage will be required to perform work in the right-of-way of Orange Road and Iowa Highway 21. Terracon will obtain a permit from the Iowa Department of Transportation to work within the Highway 21 right-of-way. We do not anticipate the need for flaggers nor closing a lane of traffic in order to complete the borings along Highway 21 and E. Orange Rd. In areas where the planned boring locations are near overhead power lines, the borings will be offset a safe distance from the power lines. Terracon will notify Iowa One Call to request 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, we consider the need for alternative subsurface exploration methods, as the safety of our exploration team members is a priority. Any 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 use of a private utility locate service would not relieve the owner of their responsibilities in identifying private underground utilities. If there are any site restrictions or special site and/or exploration requirements, these should be made known to Terracon prior to commencement of field services. Site Access and Property Disturbance: We considered that the site and boring locations can be accessed using our ATV -mounted equipment. Terracon personnel will take reasonable measures to limit the amount of damage to the property. However, some rutting of the ground surface and/or damage to landscape and vegetation could occur. Please note that our scope of services and fee do not include services associated with site clearing, wet ground conditions, or repairing existing landscape. If such services are desired by the owner, we should be notified so we can adjust our scope of services and fee. At least 2 days advanced notice will be provided to the City of Waterloo of our intent to notify Iowa One Call and perform the field exploration. Please notify Terracon if arrangements have not been made for subsurface exploration on the property. Responsive • Resourceful • Reliable EXHIBIT B - SCOPE OF SERVICES 2 of 4 Proposal for Geotechnical Engineering Services Sanitary Sewer Expansion Waterloo, Iowa July 22, 2022 Terracon Proposal No. P13225059 lrerracon We will backfill our boreholes with auger cuttings and bentonite chips after completion. Our services do not include repair of the site beyond backfilling our boreholes. Excess auger cuttings will be disposed of in an area designated by the client. Because backfill material often settles below the surface after a period, we recommend boreholes be checked periodically, and backfilled if necessary. Laboratory Testing The project engineer will review field data and assign laboratory tests to aid in our evaluation of the engineering properties of the various soil strata. Exact types and number of tests cannot be defined until completion of field work. Anticipated laboratory testing includes the following: Water content Dry unit weight Unconfined compressive strength Our laboratory testing program also includes examination of soil samples by an engineer. Based on the material's texture and plasticity, we will describe and classify soil samples in general accordance with the Unified Soil Classification System (USCS). Engineering and Project Delivery Results of our field and laboratory programs will be evaluated by a professional engineer. The engineer will develop a geotechnical site characterization, perform the engineering calculations necessary to evaluate foundation alternatives, and develop appropriate geotechnical engineering design criteria for earth -related phases of the project. Your project will be delivered using our GeoReport° system. Upon initiation, we provide you and your design team the necessary link and password to access the website. Each project includes a calendar to track the schedule, an interactive site map, a listing of team members, access to the project documents as they are uploaded to the site, and a collaboration portal. The typical delivery process includes the following: Project Planning — Proposal information, schedule and anticipated exploration plan will be posted for review and verification Site Characterization — Findings of the site exploration Geotechnical Engineering — Recommendations and geotechnical engineering report When services are complete, we upload a printable version of our completed geotechnical engineering report. Previous submittals, collaboration, and the report are maintained in our system. This allows future reference and integration into subsequent aspects of our services as the project goes through final design and construction.
