Subj: Amendment to Agreement for Subsurface Exploration for
2011 Capital Improvement Projects
Westhaven Clubhouse and Westfield Street Bridge
Oshkosh, Wisconsin
Mr. Sargent:
In accordance with your Request For Proposal on March 7, 2011, River Valley Testing Corp is
pleased to submit the following proposal for performance of a subsurface exploration at the site
of the above referenced project. This proposal is intended to formalize an outline of our general
scope of services and to provide cost information. Further, this proposal will amend our current
2011 contract to include these additional services.
RVT GEOTECHNICAL PHILOSOPHY
Since our inception in 1990, River Valley Testing Corp has made it a corporate commitment to
provide the most responsive service possible. Being the most responsive starts with decreasing
the time required to provide our recommendations. River Valley Testing Corp can provide draft
boring logs and preliminary recommendations as quickly as two days after completion of the
field work. In addition, we can often provide a final report within four weeks of receiving
authorization to proceed on a project. Being the most responsive continues with providing
recommendations which balance geotechnical concerns for the soil system with practical
construction concerns. Therefore, we have always been willing to work with owners, architects,
and design engineers to develop cost effective alternatives and recommendations for potentially
difficult site conditions.
PROJECT INFORMATION
It is our understanding, the project includes construction of a detention pond and underground
utilities at the Westhaven Clubhouse site. In addition, the Westfield Street bridge which extends
over Sawyer Creek will be redesigned and replaced in accordance with current Wisconsin
Department of Transportation standards.
City of Oshkosh March 21, 2011
2011 Capital Improvement Projects Page 2
SCOPE OF SERVICES
As requested, eleven (11) standard penetration test borings will be performed for this
exploration. Further, five (5) of the borings will be extended to 10', three (3) to 15', and three (3)
to auger refusal or a maximum depth of 60' below the existing grade.
We understand the City of Oshkosh will provide boring layout and surface elevation
determination at each borehole, and will coordinate utility clearance. Therefore, we have not
included fees for those services in our estimate. However, our estimate includes abandonment of
each borehole in accordance with Wisconsin Administrative Code NR141 and pavement
patching where necessary. We have also included fees for providing traffic control (signs, arrow
boards and /or flagmen, as necessary).
The subsurface exploration program will include limited laboratory testing, as we deem
necessary to evaluate the classification, strength, and other characteristics of the encountered
subsurface materials. As a minimum, we will perform moisture content tests on all collected
samples and calibrated spring penetrometer tests on all collected clayey soil samples. In
addition, for the Westhaven Clubhouse Pond we will perform one (1) hydraulic conductivity test.
RVT will prepare a total of two (2) written reports (one for Westhaven and one for Westfield)
that document the results of the field and laboratory test programs. Included in the reports will
be boring logs documenting the encountered soil and groundwater conditions, summary tables of
the encountered soil profiles by street, and construction considerations relative to the subsurface
conditions. Further, the Westhaven Clubhouse report will include recommendations for the
detention pond liner and embankments. The boring logs for the pond will include soil
classifications in accordance with both the USCS and USDA classification systems. The
Westfield Street Bridge report will include our recommendations concerning suitable foundation
types and depths, estimated pile capacities, lateral earth pressures, and pavement design
recommendations.
SCHEDULE
Weather permitting, we could begin the fieldwork within one to two weeks of receiving
authorization to proceed. If time becomes critical on this project, we will be available for
consultation and preliminary results of the exploration program on the third day following
completion of drilling. Further, we anticipate that our written reports will be completed by the
requested April 15, 2011 report date.

FEES
It is proposed that the fee for the performance of the above outlined services be determined on a
unit price basis. On the basis of the above Scope of Services and the attached Geotechnical Fee
Schedule, the total fee will not exceed the following amounts without authorization from the City
of Oshkosh:
Westhaven Clubhouse Pond
Mobilization: $ 50
Borings and Fieldwork: $ 500
Laboratory Testing and Report: $1,490
Westhaven Clubhouse Utility
Mobilization: $ 50
Borings and Fieldwork: $ 380
Laboratory Testing and Report: $ 500
Westfield Street Bridge
Mobilization and Traffic Control: $ 150
Borings and Fieldwork: $2,945
Laboratory Testing and Report: $_L ,'M
Total: $7,785
The above fees assume the site is accessible with a truck mounted drill rig. If an ATV mounted
drill rig is required, then we should be contacted so we can revise our proposal. The above fees
assume flagmen will not be required to control traffic at the Westfield Street Bridge site.
CONDITIONS
Should unanticipated conditions develop necessitating changes in the scope of services, our cost
will be based on the actual job work completed in accordance with the attached Geotechnical Fee
Schedule. For example, if a soft layer, such as peat, is encountered at the footing elevation, we
are likely to request the borings be extended deeper than the depth listed in the "Scope of
Services" Section of this proposal. If this situation arises, we will discuss the additional work
with you and receive your approval before proceeding.
INSURANCE
River Valley Testing Corp carries all insurance required by The State of Wisconsin. On your
project sites, RVT employees are covered by Workman's Compensation and General Liability

REMARKS
Should you decide to accept this proposal, please sign one copy of it, complete the attached
Geotechnical Project Data Sheet, and return both to us so we may properly establish your file.
We look forward to working with you on your project. If you have any questions or need
