CLIENT: Mr. Jonathan Todd
Re: Open Hole Inspection Report, 630 Lariat Rd, Silt, CO
American GeoServices, LLC (AGS) have performed a geotechnical field inspection/
evaluation at the referenced site. A detailed geotechnical evaluation and geologic hazards
assessment of any kind was beyond our scope of services.
SUMMARY OF RESULTS
Based on the results of our geotechnical field evaluation we made following
conclusions and recommendations:
•The subgrades are adequately compacted to at least 95% of ASTM D1557 equivalent
maximum dry density for the exposed subgrades and/or compacted soils.
•The allowable bearing capacity is at least 1,500 psf, for a minimum footing embedment
depth of at least 16 inches, provided proper drainage is maintained.
•It is important to assure that the bottom of footing is placed at least 16 inches below
the final finished and compated subgrade, throughout the design life of the structure.
It should be noted that a detailed geotechnical evaluation or detailed geologic hazards evaluation
of any kind was beyond our scope of services. It should also be noted that all our
recommendations are valid only if proper drainage and stormwater management as per local city,

county, and state regulations are implemented and maintained throughout the life of the
structures. No warranty of any kind is expressed or implied.
LIMITATIONS
Our Scope of Work for this project did not include any geotechnical evaluation, flood hazard
evaluation, civil engineering evaluation, or structural evaluation of any kind, or research, testing,
or assessment relative to past or present contamination of the site by any source. If such
contamination were present, it is very likely that the exploration and testing conducted for this
report would not reveal its existence. If the Owner is concerned about the potential for such
contamination, additional studies should be undertaken. We are available to discuss the scope of
such studies with you. No tests were performed to detect the existence of mold or other
environmental hazards or the presence or absence of collapsible or expansive soils, as it was
beyond Scope of Work.
Local regulations regarding land or facility use, on and off-site conditions, or other factors may
change over time, and additional work may be required with the passage of time. Based on the
intended use of the report within one year from the date of report preparation, AGS may
recommend additional work and report updates. Non-compliance with any of these requirements
by the client or anyone else will release AGS from any liability resulting from the use of this report
by any unauthorized party. Client agrees to defend, indemnify, and hold harmless AGS from any
claim or liability associated with such unauthorized use or non-compliance.
In this report, we have presented judgments based partly on our understanding of the proposed
construction and partly on the data we have obtained. This report meets professional standards
expected for reports of this type in this area. Our company is not responsible for the conclusions,
opinions or recommendations made by others based on the data we have presented.
This report has been prepared exclusively for the client, its’ engineers and subcontractors for
design and construction of the proposed structure. No other engineer, consultant, or contractor
shall be entitled to rely on information, conclusions or recommendations presented in this
document without the prior written approval of AGS.
We appreciate the opportunity to be of service to you on this project. If we can provide additional
assistance or observation and testing services during design and construction phases, please call
us at 1 888 276 4027.
