Dear Kiley Gardiner:
In accordance with your request, Atlas Technical Consultants LLC (Atlas) is pleased to submit
this proposal for a geotechnical investigation for the Preserve Park project located east of the
intersection of Eastland Drive and Pole Line Road within Twin Falls, ID.
The subsurface investigation will be conducted to provide information needed in design of the
proposed project. The project is expected to consist of a new restroom structure, an expanded
parking lot, and a community park area. The site to be developed is approximately 2.4 acres. In
addition, paved areas will be developed for the project. Retaining walls are not anticipated.
Drainage is expected to be directed to onsite infiltration facilities. Location and size of the
infiltration facilities are unknown at this time. Revisions may be required based on final design
requirements. This proposal contains our proposed scope of work, fee, and schedule.
SCOPE OF WORK
Exploration and recommendations will be prepared under the supervision of a registered
professional engineer. Qualified personnel will perform all field work. In accordance with your
request, our proposed subsurface exploration will include the following services:

Subsurface Soils Investigation
• Underground public utility locate services will be contacted prior to commencement of field
work. The client, property owner, and/or developer are responsible for private utility
locates as Atlas cannot be held responsible for the cost of replacement of utility services.
• Test pits (3) will be advanced on the site. Test pits will be backfilled at completion of
exploration. Surfaces will be left in a rough and somewhat mounded condition. Costs can
be determined if additional surface restoration is necessary.
• Soil will be classified in the field in accordance with applicable standards, including ASTM
D2488.
• Representative soil samples will be collected and transported to our laboratory for
additional testing, per ASTM or other recognized standards.
• Two infiltration tests will be performed.
Geotechnical Engineering Report
• Information regarding regional geology will be provided.
• Recommended Site Class and Seismic Design Parameters will be provided.
• Results of field and laboratory testing will be included.
• Final logs will be provided based on field classification, laboratory test data, and
classification of soils per ASTM D2487. These logs will incorporate all subsurface soil
and/or rock profile properties that may affect engineering conclusions.
• A summary of soil conditions encountered will be provided.
• Approximate exploration locations will be provided on a site map.
• Hydrology
o A review of localized groundwater conditions will be included.
o Estimated soil infiltration rates will be provided based on soil classification.
o Design infiltration rates will be reported based on site specific infiltration testing.
• Foundations and Floor Slabs-on-Grade
o Bearing capacity for applicable foundation types will be provided.
o Recommended frost embedment depths will be included.
o Foundation and floor slab subgrade preparation and drainage recommendations
will be presented.
• Applicable pavement section recommendations will be provided.
• Fill material type and placement recommendations will be presented.
• Recommendations for construction activities will be included.

COST INFORMATION
The fees outlined in this proposal are based on review of the provided project details and/or
documents, as well as our experience on similar projects. The outlined scope of work will be
billed on a lump-sum basis for a total fee of $4,605.00. The cost of services may exceed this
proposed fee if unanticipated conditions are encountered that would warrant additional
investigation or analysis, or if the proposed plans are changed from the previously stated
understanding of the project. Atlas will notify the client and obtain approval prior to incurring any
additional fees on the project. All subsequent services and communications with design
consultants or contractors will be charged in accordance with the attached fee schedule.
SCHEDULE
Atlas will proceed with the work on the basis of verbal authorization; however, please sign and
return a copy of this proposal. Public underground utility locate services will be notified as
required by law once notice to proceed is received. Utility locate services require 2 full business
days before subsurface exploration can commence. Atlas anticipates issuing our findings and
recommendations within 10 business days from the last date field work is performed or soil
samples are obtained. The attached Protect Data Sheet provides us with values used in our
design calculations. Please consult the project design team, complete the sheet to the fullest
extent possible, and return at your earliest convenience. Unless otherwise noted, Atlas will
provide only a PDF copy of the final report.
CLOSURE
This proposal is valid for 90 days from the date initiated. If you have any questions regarding this
document or if we may be of further service, please contact our office at (208) 733-5323.
Atlas sincerely appreciates this opportunity to provide professional services to you on this project.
We look forward to working with your team.
