ANY SPECIAL, CONSEQUENTIAL, INDIRECT, PUNITIVE, OR EXEMPLARY DAMAGES.
11. 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. 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. 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

EXHIBIT B - SCOPE OF SERVICES
1Ferracon
Our proposed scope of services includes field exploration, laboratory testing, and
engineering/project delivery. 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.

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.

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.

Engineering and Project Delivery
1 Ferracon
Results of our field and laboratory programs are evaluated by a professional engineer. 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

EXHIBIT B - SCOPE OF SERVICES
Derr c n
Terracon's proposed scope of services is described in the following sections and includes field,
laboratory testing, and geotechnical engineering services. 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

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.

Subsurface Exploration Procedures: The borings will be performed 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 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

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.

Engineering and Project Delivery
lFerr c.n
Results of our field and laboratory programs will be evaluated by a civil/geotechnical engineer
licensed by the State of Iowa. The engineer will develop a geotechnical site characterization,
perform the engineering calculations, 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 (if not previously
registered). 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 reports
When services are complete, we upload printable versions of our geotechnical engineering
reports. Previous submittals, collaboration, and the reports, 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.
The geotechnical engineering report for the sanitary sewer and road reconstruction will address
and/or include the following:
• General site and project description
® Site and Boring Location diagrams
• Stratified boring logs with field and laboratory data
• Subsurface exploration procedures
• Summaries of soil, rock, and groundwater conditions encountered
• Summary of laboratory test results
▪ Earthwork recommendations for pavements including:
• Subgrade evaluations
• Anticipated undercut/overexcavation depths, where applicable
® Suitable on -site and imported fill material types
® Fill placement and compaction requirements
• General grading and drainage recommendations
• General earthwork considerations
• Typical pavement thicknesses for asphaltic and portland cement concrete sections
• General subsurface drainage recommendations and construction dewatering
considerations, where applicable
• Frost considerations

The geotechnical report for trenchless construction of the sanitary sewer at the railroad spur
crossings will include and/or address the following:
• General site and project description
e Site and Boring Location diagrams
• Stratified boring logs with field and laboratory data
• Photographs of recovered rock core samples
• Subsurface exploration procedures
• Summaries of soil, rock, and groundwater conditions encountered
• General site geology
• Summary of laboratory test results
• Geotechnical discussion regarding the feasibility of trenchless installation methods
• Geotechnical parameters with depth including:
® Unit weight
• Angle of internal friction or cohesion
o Active and passive earth pressure coefficients
• Estimated ground surface settlement considering an assumed overcut dimension
• Settlement monitoring program requirements during construction
• Estimated seismic site class based on the data obtained
• Dewatering considerations
• General backfilling and compaction recommendations
Please note that in order for Terracon to finalize a subsurface exploration program and provide
geotechnical engineering recommendations for the project, we will require sewer plan and profile
drawings that includes the proposed pit areas. Other information may also be required.
Preparation and Review of Claassen Engineering's Performance Specification: Terracon's
geotechnical engineering report and associated verbal and written communications will be used
by WCES for incorporation in the bid documents, and will be used by the contractor to develop
their designs and construction monitoring program. Terracon will assist WCES in the preparation
of earth -related portions of the railway crossing performance specifications and will review project
plans and the performance specification prepared by WCES. Our review will include a written
statement, which conveys our opinions, related to the plans and specifications' consistency with
our geotechnical engineering recommendations and American Railway Engineering and
Maintenance -of -Way Association (AREMA) and CN requirements.
