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 taw. 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 perfuming 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 a 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 Consultants 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 cornpletion of the testing procedures (unless stated otherwise in the Services). Client shall furnish or cause to be fumished 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. Wok product, such as reports, logs, data, notes, or calculations, prepared by Consunant 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 Consultants document retention policies and practices. 16. Utilities. 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.

Aspects of the project, undefined or assumed, are highlighted. We request that Strand Associates verify and provide the information, if available, prior to initiation of field services. Site Location and Anticipated Conditions Item j Description Site Location The project site is located 3505 Easton Avenue in Waterloo, Iowa. Refer to Exhibit D. Existing Improvements Structures are present adjacent to or in the vicinity of the new structures planned and underground utilities are present at the plant. Current Ground Cover Existing fill, pavements, and grass Existing Topography The ground surface at the WWTP is relatively flat. Terracon has a significant amount of subsurface information at the Waterloo WWTP and performed construction testing services during various WWTP projects. Based on our experience at the site, the Anticipated subsurface profile generally consists of existing fill over alluvial sands with Subsurface Conditions fines and seams and layers of fine-grained soil. The composition of the existing fill varies, and its thickness is generally about 3 to 8 feet. Bedrock is expected to be at least 50 feet below existing grades within the proposed project areas.

Proposed Construction • Three (3) lightly -loaded masonry buildings with slabs -on -ground are planned. Spread footing foundations are planned for the buildings; however, a depressed mat foundation is also being considered for the Ferric Building. The Centrate Equalization Tank is proposed to be about 75 by 45 feet, extend about 22 feet below -grade, and be of cast -in-place reinforced concrete construction. New pavements are also planned in the vicinities of the new structures. More detailed information for the improvements planned, including anticipated bearing elevations of the foundation, are included in Exhibit D. Maximum Structure Loads and Contact Pressures • Building walls: 3 kips per linear foot (klf) • Tank mat: 1.5 to 3 kips per square foot (ksf) • Building floor slabs: 200 pounds per square foot (psf) Maximum Site Grading We considered that changes to the existing grades (i.e., cut and fill) will be 3 feet or less, for the purposes of preparing this proposal. EXHIBIT A - PROJECT UNDERSTANDING 2 of 2 Proposal for Geotechnical Engineering Services Wastewater Treatment Plant Biosolids Modifications E Waterloo, Iowa March 18, 2019 m Terracon Proposal No. P13195025 EXHIBIT B - SCOPE OF SERVICES lierracon Our proposed Scope of Services consists of field exploration, laboratory testing, geotechnical engineering, and project delivery. These services are described in the following sections. Field Services Safety: Terracon is currently not aware of environmental concerns at this project site that would create health or safety hazards associated with the 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, work gloves, 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. Screening of samples will be performed on-site, however, and if PID readings are obtained that are deemed to be of concern, exploration at that location will be terminated and Terracon's findings discussed with the City of Waterloo WMS personnel and Strand Associates. Terracon will notify Iowa One Call to request location and marking of public utilities at least 48 hours prior to performing borings/excavations. We consult with the City of Waterloo WMS personnel regarding underground utilities or other underground hazards. Based on the results of this consultation, we will consider the need for alternative subsurface exploration methods, as the safety of our exploration team members is a priority. An on-site utility locate meeting is planned to be conducted for this project. Any private utilities should be marked by the City of Waterloo personnel 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 City of Waterloo WMS personnel are not able to accurately locate private utilities, Terracon can assist the owner/client by using geophysical instruments. Fees associated with location and marking of private utilities are considered additional services and are not included in the proposed scope of services. Upon request, the estimated fee for the location and marking of private utilities would be forwarded to the City of Waterloo WMS for approval. The use of a private utility locate service would not relieve the owner/client of their responsibilities in identifying 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: Terracon considered that the site and boring locations can be accessed using our track -mounted drill rig. 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. Please note that our scope of services and fee do not include services associated with site clearing, wet ground nsve ■ Resourceful EXHIBIT B - SCOPE OF SERVICES 1 of 5 Proposal for Geotechnical Engineering Services Wastewater Treatment Plant Biosolids Modifications m Waterloo, Iowa March 18, 2019 Terracon Proposal No. P13195025 lierracon conditions, or reparations to existing landscape. If such services are desired, Terracon should be notified so the scope of services and fee can be modified. At least 3 days advanced notice will be provided to the City of Waterloo WMS of Terracon's intent to notify Iowa One CaII and perform the subsurface exploration. Boreholes will be backfilled with auger cuttings and bentonite chips after completion. Terracon's scope of services does not include repair of the site beyond backfilling the boreholes. Any excess auger cuttings will be disposed on-site, as directed otherwise by City of Waterloo WMS personnel. Because backfill material often settles below the surface after a period, Terracon recommends the boreholes be checked periodically, and backfilled if necessary. Boring Locations and Elevations: Prior to conducting an on-site utility locate meeting, Terracon will determine the boring locations in the field using the site plans provided by Strand Associates. The latitude and longitude of the borings will also be determined with a handheld GPS unit, which has a minimum horizontal accuracy of about 20 feet. Surface elevations at the boring locations will be determined using differential leveling techniques and benchmark references provided by Strand Associates. Surface elevations at the boring locations will be reported to the nearest %- foot. 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 Strand Associates stake the boring locations and provide surface elevations at the boring locations to Terracon. Subsurface Exploration Program: Refer to Exhibit D for the boring program requested by Strand Associates. The requested base exploration program includes performing twelve (12) borings with a total of 330 feet of drilling. The subsurface exploration program requested includes six (6) borings to depths of 25 feet below existing grades for the buildings, four (4) borings to depths of 40 feet for the Centrate Equalization Tank, and two (2) borings to depths of 10 feet in for new pavements. Subsurface Exploration Procedures: The borings will be advanced with a rotary drill rig using hollow -stem augers and mud -rotary drilling methods. Sampling will be performed using a split barrel sampler or thin-walled tubes. In the split -barrel sampling procedure, a standard 2 -inch outer diameter split -barrel sampling spoon is driven into the ground with a 140 -pound, automatic hammer with a 30 - inch drop. 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. 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. Sampling in building and pavement areas will be performed at intervals of 2.5 feet in the upper 15 feet and at intervals of 5 feet thereafter to the boring termination depths. Sampling in borings for the Centrate Equalization Tank will be performed at intervals of 5 feet in the upper 15 feet, EXHIBIT B - SCOPE OF SERVICES 2 of 5 Proposal for Geotechnical Engineering Services Wastewater Treatment Plant Biosolids Modifications ■ Waterloo, Iowa March 18, 2019 ■ Terracon Proposal No. P13195025 lrerracon followed by sampling intervals of 2.5 feet to 30 feet, and then at intervals of 5 feet thereafter to the boring termination depths. Groundwater level observations will be recorded during and after drilling and sampling. In some instances, groundwater observations may not be representative after boring and sampling because drilling fluid or water were used for drilling. 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, sample recoveries, groundwater level observations, and other relevant drilling and sampling information. Our field logs also include visual descriptions of materials encountered during drilling and the exploration team's interpretation of subsurface conditions between samples. The samples are placed in containers and transported to our laboratory for further testing and classification. Terracon's engineering staff and exploration team communicate during the subsurface exploration. If the soil conditions encountered appear to be unfavorable or marginal at the planned boring termination depth, the subsurface exploration can be modified while the exploration team is on-site. If additional fees apply, Terracon will contact the City of Waterloo and Strand Associates for authorization, prior to performing any additional services. Field Screening of Recovered Samples: Personnel trained in environmental data collection will screen the soil samples obtained from the borings. Each sample will be appropriately bagged, allowed to equilibrate for at least 20 minutes and then tested on-site for the presence of refined petroleum hydrocarbons (PHCs) utilizing a calibrated photoionization detector (PID). The soil will also be subjectively evaluated for odor and/or discoloration. The data along with lithology descriptions will be recorded on the log for each boring and included within the geotechnical report. Laboratory Testing The project engineer will review field data and assign laboratory tests to aid in the evaluation of the engineering properties of various soil strata. The proposed laboratory testing program includes the following: ■ Water content (testing on about 50% of 96 samples planned) ■ Unit dry weight (estimated to be <_ 12 tests) • Atterberg limits (estimated to be <_ 1 test) ■ .Sieve analysis w/ P200 (1 test planned for dewatering considerations) ■ Unconfined compressive strength (estimated to be <_ 12 tests) EXHIBIT B - SCOPE OF SERVICES 3 of 5 Proposal for Geotechnical Engineering Services Wastewater Treatment Plant Biosolids Modifications E Waterloo, Iowa March 18, 2019 N Terracon Proposal No. P13195025 lierracon Our laboratory testing program includes examination of soil samples by an engineer and/or a geologist. 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). Samples recovered during the subsurface exploration will be retained in our office for a period of 120 days after submittal of our geotechnical engineering report so that additional testing can be performed upon request. Engineering and Project Delivery Field exploration, laboratory testing, site characterization, and geotechnical engineering services will be performed by and/or under the supervision of an experienced civil/geotechnical engineer licensed by the State of Iowa. Your project will be delivered using our GeoReport. system. 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 the geotechnical engineering report is complete, Terracon will provide copies to the City of Waterloo and Strand Associates. Terracon will also upload a 'pdf' version of the report to our GeoReport° system. Previous submittals, collaboration, and the report will be 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. The geotechnical engineering report will include and/or address the following: General site and project description ▪ Site and Boring Location diagrams Stratified boring logs with field and laboratory data ▪ Subsurface exploration procedures Summary of laboratory testing performed ® Summaries of soil and groundwater conditions encountered Geotechnical design recommendations for spread footing and mat foundations including: • Minimum widths and minimum embedments for frost protection Anticipated suitable bearing depths Net allowable bearing pressure(s) • Subgrade response modulus • Estimated total and differential settlement • Parameters for uplift/buoyancy resistance General foundation construction considerations EXHIBIT B - SCOPE OF SERVICES 4 of 5 Proposal for Geotechnical Engineering Services Wastewater Treatment Plant Biosolids Modifications N Waterloo, Iowa March 18, 2019 ■ Terracon Proposal No. P13195025 lierracon Estimated seismic site class based on the data obtained Recommendations for design and construction of building floor slabs Recommended modulus of subgrade reaction(s) for floor slab subgrades Earthwork recommendations for foundations, floor slabs, and pavements including: • Subgrade evaluations ▪ Anticipated stripping depths and undercut/overexcavation depths, where applicable Discussion regarding corrective earthwork approaches • Suitable on-site and imported fill material types • Fill placement and compaction recommendations • General grading and drainage recommendations • General earthwork considerations Lateral earth pressure recommendations • Typical pavement thicknesses for asphaltic and portland cement concrete sections E Considerations for groundwater control and subsurface drainage, where applicable Frost considerations Please note that in order for Terracon to provide more specific geotechnical engineering recommendations for development of the project design, the following information would be beneficial for use in the geotechnical evaluations. • Topographic Site and Grading Plans • Building floor slab elevations and loads Traffic loading information and pavement design period (we'll consider 20 years otherwise) Review of Strand Associates' Final Plans and Specifications: Terracon's geotechnical engineering report will be included in the bid documents and used by Strand Associates for preparation of the designs, plans, and specifications. Terracon will review earth -related portions of the project plans and specification prepared by Strand Associates. Terracon's review will include a written statement, which conveys our opinions, related to the consistency of the plans and specifications with our geotechnical engineering recommendations.

Terracon Consultants, Inc. 2640 12th Street Southwest Cedar Rapids, IA 52404 Re: Wastewater Treatment Plant Biosolids Modifications City of Waterloo, Iowa (Owner) Dear Mr. Lisi: On behalf of Owner, Strand Associates, Inc.® (Strand) is sending you this request for cost proposal for Geotechnical Services. Project Description Strand is in the process of designing improvements to the existing wastewater treatment plant. The main new structures to be constructed as part of this project include the following: 1. Waste Activate Sludge (WAS) Building Addition 2. Dewatering Building Addition 3. Centrate Equalization Tank 4. Ferric Building 5. Pavement Removal and Reinstallation Enclosed is a Preliminary Location Map showing the location of the anticipated improvements. These structures are described in more detail in the following paragraphs. WAS Building Addition The WAS Building addition will be an approximate 20 -foot -wide by 40 -foot -long on -grade structure including masonry walls with precast plank roof, concrete frost walls, and continuous strip footings. The floor slab will be a 6 -inch fiber -reinforced concrete slab -on -grade with approximate finished floor el. 842.00. Footings will bear at approximate el. 837.00 and unfactored wall loads will be on the order of 2 kips per foot. Dewatering Building Addition The Dewatering Building addition will be an approximate 20 -foot -wide by 72 -foot -long on -grade structure consisting of masonry walls with precast plank roof, concrete frost walls, and continuous strip footings. The floor slab will be a 6 -inch fiber -reinforced concrete slab -on -grade at approximate finished floor El. 839.50. Footings will bear at approximate el. 834.50 and unfactored wall loads will be on the order of 3.0 kips per foot.

Mr. Tom Lisi, P.E. Terracon Consultants, Inc. Page 2 March 11, 2019 Ccntratc Equalization Tank The Centrate Equalization Tank will be a 75 -foot by 45 -foot below -grade by 22 -foot deep concrete tank with top of wall at approximate el. 841.00 and mat slab bearing at approximately el. 818.00. Expected contact pressure at the bottom of the mat slab will be approximately 1.5 kips per square foot. Ferric Building The Ferric Building will be an approximate 28 -foot -wide by 44 -foot -long masonry structure with concrete frost walls and strip footings and a concrete slab -on -grade floor. An alternative design would have a mat slab chemical storage area bearing approximately 4 to 5 feet below grade, with below -grade building walls bearing on the mal slab. Finished floor is expected to be at approximately El. 837.00 and mat slab or footings are expected to bear at approximate el. 832.00. Expected loads for the strip footings are 2.0 kips per foot. Expected edge loads for the mat slab alternative are approximately 3.0 kips per foot, yielding a maximum soil pressure of approximately 1 kip per square foot. Access Road Site driveways and parking areas in the vicinity of the new structures will be removed and replaced. Most pavement is expected to consist of simple replacement in areas that are already paved. There will be a small amount of paving of previously unpaved areas. Project Scope Geotechnical Engineering Services Boring No. B-1, B-2 B-3, B-4 B-5 through B-8 B-9, B-10 B-11, B-12 TABLE 1—BORING DESCRIPTION—BASE SCOPE OF SERVICES Base Scope Depth (feet) Structure 25 WAS Building Addition 25 Dewatering Building Addition 40 Centrate Equalization Tank 25 Ferric Building 10 Access Road Remarks Two borings Two borings Four borings Two borings Two borings Provide one boring each in the pavement areas north and south of the Dewatering Building. The base scope of services (number and depth of borings) has been determined based on past projects of a similar nature. The geotechnical engineer shall provide a fee for this base scope to provide Owner with consistent criteria for one aspect of its evaluation of the proposals. The geotechnical engineer shall make an independent assessment of the field exploration and testing necessary to provide the geotechnical information requested in this letter and needed for design. Fees for any services beyond the base scope WDM:sjl\\\\strandcom\projects \MAD\4400 -4499\4463\004\Designs-Studies-Reports\ Geotechnical\Geotechnical RFP\waterloo iageotech RFP.docx www.strand.com Exhibit D Strand Associates, in Mr. Tom Lisi, P.E. Terracon Consultants, Inc. Page 3 March 11, 2019 shall be included separately in the proposal. If no additional services are proposed, it is understood that the geotechnical engineer concurs that the base scope is sufficient to provide the information requested. Boring depths are estimated depths assuming no auger refusal. Should bedrock be encountered, the intent is for drilling to extend only to auger refusal on bedrock for typical borings. Should bedrock be encountered, a 5 -foot rock core shall be performed for one boring per structure. Unconfined compressive strength tests shall be conducted and rock quality designation values shall be determined for the rock core samples. Contingency costs for rock coring and analysis shall be included as a separate line item in the proposal. The layout of the new improvements is preliminary. Structure locations may change slightly during final design. If the subsurface conditions require additional or changed borings or other evaluations appear to be necessary to provide the desired information, please advise Strand and Owner. The geotechnical work shall include the following items: 1. Contact wastewater treatment plant staff and local utility companies for underground utility locations. Review existing site underground piping drawings with the utilities. Discuss presence of other underground utilities and/or facilities with Owner and obtain location information. Choose the location for each boring to avoid any conflicts with underground utilities and facilities. 2. Mobilize drilling crew and equipment to project site and return. 3. Stake soil boring locations and ground elevations. Determine exact field locations for each boring. 4. Perform standard soil borings with a 2 -inch outside diameter split barrel sampler driven 18 inches with a 140 -pound weight falling 30 inches (American Society for Testing and Materials D1586), unless otherwise recommended by the geotechnical engineer. 5. Provide photoionization detector (PID) readings of soil or rock core samples recorded on the soil boring logs. Readings shall be taken in the field by placing a portion of the sample in a Ziploc® bag, allowing the sample to reach room temperature, inserting the PID probe into a corner of the bag, and recording the highest reading. 6. Measure water levels in the borings during drilling, at the completion of the drilling, and 24 hours after completion of drilling. 7. Backfill bore holes in accordance with code requirements. 8. Perform laboratory tests as necessary to determine general strength and settlement characteristics of the soil. 9. Classify soils. Provide drawing of soil boring records and analyses of results. Particle size gradations shall be provided to determine whether on-site soils are suitable for use as fill and backfill. 10. Classify fill soils from borings, including a determination of whether any potential hazardous or petroleum waste material or solid wastes are present. These classifications and determinations WDM:sjl\\\\strandeam\projects \MADW400--4499\4463\004\Designs-Studies-Reports\Geotechnical \Geotechnical RFP \waterloo iageotech RFP.docx www.strand.corn Exhibit D Strand Associates, inc. Mr. Tom Lisi, P.E. Terracon Consultants, Inc. Page 4 March 11, 2019 shall be based on field observations of samples and drilling spoils and PID readings, not on laboratory analysis or other testing of the samples. Note all observations on the soil boring logs. 11. Provide additional geotechnical evaluations as recommended by the geotechnical engineer. 12. Provide project coordination, project administration, and geotechnical report. The geotechnical report shall include the following items at a minimum and any additional geotechnical information required for the design and construction of the facility: a. Presence or absence of rock, old excavation, or fill. Rock shall be sampled to determine whether it can be excavated. b. Suitability of the site for the structure to be built thereon. c. Classification of soil strata after appropriate sampling. d. General type of foundation that will be required at the site. e. Elevation of groundwater and whether dewatering is anticipated. f. Homogeneity and compressibility of the soils across the site and evaluation of the anticipated total and differential settlement of the structures. g. Bearing capacity of the soil and depth at which footings must be founded. h. Recommendations for deep foundations where deemed necessary because of soil conditions including the following: (1) Type of deep foundation (e.g., driven piles, drilled piers). (2) Type of piles (e.g., H -piles, pipe piles). (3) Estimated size, depth, end bearing, and skin friction design values for piles, drilled piers, or other deep foundations. i. Geotechnical design parameters including lateral earth pressure for design of below -grade structures and earth -retaining structures, subgrade modulus for design of floors and mat foundations, and recommended design groundwater levels. j. Asphalt and concrete pavement design recommendations. k. Seismic Design Site Class in accordance with the 2015 International building Code. 1. Elevations of the existing grade and other topographical features that may affect the foundation design of construction. 13.
