not limited to the Project Information section, unless the Project is oiherwise described in Exhibit A to this Agreement (which section or Exhibit is
incorporated into this Agreement).
1. Scope of Services. The scope of Consultant's services is described in the Proposal, including but not limited to the Scope of Services seciion
("Services"), unless Services are otherwise described in Exhibit B to this Agreement (which section or exhibit is incorporated into this Agreement).
Portions of the Services may be subcontracted. Consultant's Services do not include the investigation or detection of, nor do recommendations in
Consultant's reports address the presence or prevention of biological pollutants (e.g., mold, fungi, bacteria, viruses, or their byproducts) or occupant
safety issues, such as vulnerability to natural disasters, terrorism, or violence. If Services include purchase of software, Client will execute a separate
software license agreement. ConsultanYs findings, opinions, and recommendations are based solely upon data and information obtained by and
furnished to Consultant at the time of the Services.
2. Acceptance/ Termination. Client agrees that execution of this Agreement is a material element of the consideration Consultant requires to
execute the Services, and if Services are initiated by Consultant prior to execution of this Agreement as an accommodation for Client at Client's
request, both parties shall consider that commencement of Services constitutes formal acceptance of all terms and conditions of this Agreement.
Additional terms and conditions may be added or changed only by written amendment to this Agreement signed by both parties. In the event Client
uses a purchase order or other form to administer this Agreement, the use of such form shall be for convenience purposes only and any additional or
conflicting terms it contains are stricken. This Agreement shall not be assigned by either party without prior written consent of the other party. Either
party may terminate this Agreement or the Services upon written notice to the other. In such case, Consultant shall be paid costs incurred and fees
earned to the date of termination plus reasonable costs of closing the Project.
3. Change Orders. Client may request changes to the scope of Services by altering or adding to the Services to be performed. If Client so requests,
Consultant will return to Client a statement (or supplemental proposal) of ihe change setting forth an adjustment to the Services and fees for the
requested changes. Following ClienYs review, Client shall provide written acceptance. If Client does not follow these procedures, but instead directs,
authorizes, or permits Consultant to perform changed or additional work, the Services are changed accordingly and Consultant will be paid for this work
according to the fees stated or its current fee schedule. If project conditions change materially from those observed at the site or described to
Consultant at the time of proposal, Consultant is entitled to a change order equitably adjusting its Services and fee.
4. Compensation and Terms of Payment. Client shall pay compensation for the Services perFormed at the fees stated in the Proposal, including

which they are issued. Fees do not include sales tax. Client will pay applicable sales tax as required by law. Consultant may invoice Client at least
monthly and payment is due upon receipt of invoice. Client shall notify Consultant in writing, at the address below, within 15 days of the date of the
invoice if Client objects to any portion of the charges on the invoice, and shall promptly pay the undisputed portion. Client shall pay a finance fee of
1.5% per month, but not exceeding the maximum rate allowed by law, for all unpaid amounts 30 days or older. Client agrees to pay all collection-related
costs that Consultant incurs, including attorney fees. Consultant may suspend Services for lack of timely payment. It is the responsibility of Client to
determine whether federal, state, or local prevailing wage requirements apply and to notify Consultant if prevailing wages apply. If it is later determined
that prevailing wages apply, and Consultant was not previously notified by Client, Client agrees to pay the prevailing wage from that point forward, as
well as a retroactive payment adjustment to bring previously paid amounts in line with prevailing wages. Client also agrees to defend, indemnify, and
hold harmless Consultant from any alleged violations made by any governmental agency regulating prevailing wage activity for failing to pay prevailing
wages, including the payment of any fines or penalties.

1. Based on our experience and review of the Iowa Geological Survey - GeoSam well in the
vicinity of the project site, bedrock is anticipated within about 50 to 100 feet below the
ground surface.
2. The anticipated boring depth is based on the expected depth to auger refusal in
bedrock.
3. See Exhibit E for approximate boring locations. We understand that the boring locations
may be updated, and the revised boring locations/coordinates and surface elevations
will be provided by HHE prior to our field mobilization.
4. Per HHE, if the boring is located along the edge of W Cemetery Road, then this boring
may need to extend to 30 feet in depth.
Site Access: Terracon must be granted access to the site by the City of Fairfax. We will
notify the City of Fairfax and HHE at least 2 business days prior to our field mobilization.
Utility Locate: Terracon will contact the local Iowa One Call service to request the
location of utilities owned by member companies. Locating private lines on private
property is not part of the Iowa One Call member companies or Terracon's scope. All
private utilities should be marked by the City of Fairfax or HHE prior to the
commencement of our field exploration.
Traffic Control: We understand the existing bridge is currently open to traffic with the
average daily traffic (ADT) of 640 vehicles per day (VPD) and we have assumed it to be
the same at the time of our field exploration and that traffic control will be required for

the borings performed near W. Cemetery Road. We assume the traffic control will consist
of closing 1 lane and providing signage.
Boring Layout and Elevations: We understand the borings will be staked by HHE and
the coordinates and elevations will be provided to Terracon. If offsets are required due
to access issues or existing utilities, HHE will be notified, and the boring will be
performed at the offset location upon HHE's approval. Approximate boring surface
elevations provided by HHE will be utilized and change in elevation for any offsets will be
measured in the field.
Subsurface Exploration Procedures: We will advance borings with an ATV- or a
track-mounted drill rig using continuous flight augers (solid stem and/or hollow stem, as
necessary, depending on soil conditions) and/or rotary wash boring techniques.
Sampling will be performed at intervals of 5 feet using split-barrel sampling procedures.
The split-barrel samplers will be driven in accordance with the standard penetration test
(SPT). Upon encountering bedrock, SPT resistance values (N-values) will be recorded
at/near the top of the bedrock and at final refusal. We will observe and record
groundwater leveis while drilling/sampling if encountered prior to mud-rotary drilling
techniques. The samples will be containerized and transported to our laboratory for
testing and classification by a geotechnicai engineer.
Our exploration team will prepare field logs as part of standard drilling operations
including sampling depths, penetration resistances, and other relevant sampling
information. Field logs include visual classifications of materials observed during drilling
and our interpretation of subsurface conditions between samples.
Property Disturbance: Terracon will make reasonable efforts to reduce damage to the
property. However, it should be understood that during the normal course of our work,
some disturbance could occur including rutting of the ground surface and damage to
landscaping. Our services do not include repair of the site beyond backfilling our
boreholes. Excess auger cuttings will be dispersed in the general vicinity of the
boreholes. Because backfill material often settles below the surface after a period, we
recommend boreholes are checked periodically and backfilled, if necessary. We can
provide this service, or grout the boreholes, for additional fees at your request.
Safety: Terracon is not currently aware of environmental concerns at the 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 OSHA Class D
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 boring logs.

Laboratory Testing
We have assumed that laboratory testing will consist of performing moisture content
tests on recovered soil and disturbed rock samples.
Based on the material's texture and plasticity, we will describe and classify soii samples
in general accordance with the Unified Soil Classification System (USCS); the bridge
boring soil samples will also be classified in general accordance with the Iowa DOT BDM
Table 6.2.7-2. Bedrock classification will be conducted using locally accepted practices
for engineering purposes per the Description of Rock Properties, as well as per Iowa DOT
BDM Table 6.2.7-1.
Engineering and Project Delivery
The results of our field and laboratory programs will be evaluated, and a geotechnical
engineering report will be prepared under the supervision of a licensed professionai
engineer. The geotechnical engineering report will provide the following:
