APPROACH TO THE PROJECT
The purpose of the scope of service presented herein is to provide additional subsurface data
within the proposed roadway improvement areas . Specifically, the additional explorations
proposed herein will be performed relative to :
1 . The delineation of the extent of organic (A-8 ) soils encountered during our previous
exploration .
2 . The roadside canals to be reclaimed (or filled ) between approximate Station No ' s .
281 +00 to 295+ 00 and between approximate Station Nos . 322 +00 to 330+00 .
3 . The slope stability analysis of the proposed slope cut located adjacent to the Red Stick
property, between approximate Station No 's . 306 + 00 to 320+ 00 .
4 . To further evaluate our normal seasonal high groundwater table estimate between
approximate Station No 's . 281 + 50 to 310+00 , between approximate Station No 's .
319+00 to 362 + 00 and between approximate Station No 's . 750 + 00 to 771 +50 .

This proposal presents our approach to the project and includes an estimate of field exploration
and laboratory testing quantities as well as engineering resources needed for the evaluation of
the data obtained and preparation of a report.
_PROPOSED M n SERVICES
Ardaman & Associates , Inc. will provide geotechnical engineering services for this phase of the
Project including a review of existing information , field reconnaissance , Standard Penetration
Test( SPT) borings , auger borings and manual muck probes . The scope of service for this phase
of the proposed roadway improvements will include the following :
1 . Perform up to 45 auger borings to an approximate depth of 6 feet within the two areas alon
the roadway where organic (A-8) soils were encountered during our previous exploration . g
2 . Perform manual muck probes within the roadside canals to be reclaimed (or filled )between
approximate Station No 's . 281 +00 to 295 + 00 and between approximate Station No 's . 322 + 00
to 330 +00 . The purpose of the muck probes is to preliminarily measure the depth of soft organic
soils and/or sediment , if present within the existing canals . These probes are performed by
hand -pushing 1 -inch diameter steel rod into the ground until penetration is refused . Generally,
the probes can be pushed through very soft organic and/or clayey soils , and terminate upon
encountering sandy soils or relatively stiff clays . Probes can also be terminated on obstructions
such as roots or buried debris . It is possible that probes could terminate under one of the above
scenarios , while muck could still exist below the probed depth .
3 . Perform up to 20 auger borings to an approximate depth of 6 feet between approximate
Station No 's . 281 +50 to 310+00 , between approximate Station No 's . 319 + 00 to 362+ 00 and
between approximate Station No 's . 750+00 to 771 + 50 to further evaluate our normal seasonal
high groundwater table estimate .
4 . Perform up to two Standard Penetration Test (SPT) borings to an approximate depth of 35
feet in close proximity to the proposed slope cut located adjacent to the Red Stick property. We
note that the existing slope to be analyzed was observed to be densely wooded and
inaccessible to our truck-mounted drilling equipment. Therefore , this proposal includes an
estimated cost for limited land clearing . The clearing is intended to be limited in scope , and will
be performed to provide access to proposed drilling locations within the slope . We note that
Ardaman & Associates , Inc . cannot be held responsible for potential damage to wetland and/or
upland ( protected ) vegetation , or endangered and/or threatened species of animals . If such
concerns exist on the site , we recommend an experienced environmental specialist be present
during clearing activities . The client is responsible for coordinating permission to access the site
with the current property owner.
5 . Obtain soil samples from the SPT and auger borings for laboratory testing . This includes
etc .
routine classification tests including standard sieve analysis , Atterberg Limits , organic contents ,
6 . Prepare a report including all data developed during the laboratory and field programs , and
our recommendations relative to soil and groundwater parameters to be used in the design .
In addition , we will analyze the global stability of the proposed slope cut (for its proposed
geometry and encountered soil conditions ) against failure by circular are , infinite slope
or sliding block type failure . We understand that for this purpose , slope cross sections

will be provided by the client or their design consultant . Geometry will need to extend
a minimum of 40 feet out from the existing toe of slope . We note that for the seepage
portion of the stability analyses , relative permeability will be assigned to each of the
encountered soil strata . This assumes that the actual quantity of seepage through the
slope is not required for the project . If estimates of seepage quantity are required , this
proposal will need to be revised to incorporate field and/or laboratory permeability
testing
All work shall also comply with the current Florida Minimum Technical Standards .
COMPENSATION .
The COUNTY agrees to pay, and the Geotechnical Professional agrees to accept , a fee for
services rendered according to the above " Scope of Services " and identified in the attached
EXHIBIT "A" Fee Schedule .
A Not-to- Exceed Amount of: $ 16 , 946 . 00 to be paid on a unit price basis for actual work
performed in accordance with the schedule of services and fees set forth in Exhibit A of
RENEWAL OF THE ANNUAL GEOTECHNICAL SERVICES CONTRACT IRC RFQ NO .
2008071 WITH ARDAMAN & ASSOCIATES INC . Effective Date : November 18 , 2008 .
TIME FOR COMPLETION

geotechnical work will be as follows :
• Project start- up , boring layout and utility clearance and Field Exploration — 2 to 3 Weeks
• Laboratory testing — 2 weeks
• Engineering analysis , preparation and submittal of draft report — 1 to 2 weeks
• Finalize report - 1 week

Exhibit A
COST ESTIMATE
Based on our knowledge of the project to-date , the costs associated with the aforementioned tasks
are presented below . Unit rates for personnel and field explorations are in accordance with those
set in the continuing service agreement between Ardaman & Associates , Inc . and Indian River
County . The actual cost of our services will be a function of the quantities of work performed in
accordance with the cost estimate presented below.
This cost is based on the assumption that maintenance of traffic ( M . O . T . ) will not be needed for the
performance of the SPT and/or auger borings . If it is determined that M . O .T . will be needed for
some of the boring locations , we can coordinate the necessary services at an additional charge for
the time and materials necessary .
