TSF Proposal No.: 2202-121
Dear Robert:
As requested, Tierra South Florida, Inc. (TSF) is pleased to submit this proposal for the above-
referenced project. Based on information provided by McFarland-Johnson, proposed construction
will consist of dumpster pad, with block walls with foundations into the limestone to prevent
overturning.
PROPOSED SCOPE OF WORK
Our scope of work will consist of:
Two (2) Standard Penetration Test (SPT) borings to a depth of 25 feet.
Laboratory Testing of soil samples recovered from SPTs.
A report will be issued that contains the exploration data, geotechnical recommendations
for foundation design, and a discussion of some construction considerations.
Prior to drilling at the project site, TSF will notify the local utility companies and request that
underground utilities be marked. Our experience, however, is that the utility companies will not
mark privately owned utilities. Locating utilities on the air si
responsibility. Our proposal assumes that utility lines on the air side will need be located in
the field by others prior to mobilization of the drill rig. TSF will recommend a utility line
locating service upon request. We believe that significant coordination will likely be required to
perform the field operations. This proposal is based on the assumption that 1) all boring
locations are open and accessible to a truck mounted drill rig.

ESTIMATED FEES
It is proposed that the fee for the performance of the services outlined above is determined on a
unit price basis in accordance with the attached Fee Schedule and that the work be performed
enclosed herewith and incorporated into this proposal. On
the basis of the proposed quantities, it is estimated that the total fee will be approximately
$9,557.50.
Our estimate covers the work needed to present the results. Not included are post design services
such as reviews of drawings, preparation of construction specifications, special conferences, and
SCHEDULE AND AUTHORIZATION
TSF will proceed with the work after receipt of a signed copy of this proposal. With our present
schedule, we can commence work within several days of project approval (weather permitting)
and fieldwork is expected take about 8 to 9 days to complete. The report can be submitted in about
four weeks after completion of the field work.
We at TSF appreciate the opportunity to submit this proposal and look forward to working with
you on this project. If you should have any questions concerning our proposal, please contact our
office.
Respectfully submitted,
