In order to understand the scope of the work intended under a permit application and expedite the
issuance of a permit it is important that complete information be provided. When reviewing a plan
and it's discovered that required information has not been provided by the applicant, this will result
in the delay of the permit issuance and in proceeding with building construction. The owner or
contractor shall be required to provide this information before the plan review can proceed. Other
plans that are in line for review may be given attention before the new information may be reviewed
after it has been provided to the Building Department.
Please review this document to determine if you have enough information to design your
project and provide adequate information to facilitate a plan review. Also, please consider
using a design professional for assistance in your design and a construction professional for

PURPOSE AND SCOPE OF STUDY
This report presents the results of a subsoil study for a proposed residence to be located
on Lot 133, Silver Mountain Drive, Ironbridge Development, Garfield County, Colorado.
The project site is shown on Figure 1. The purpose of the study was to develop
recommendations for the foundation design. The study was conducted as a supplement to
our agreement for geotechnical engineering services to L.B. Rose Ranch, LLC dated July
24, 2003. We previously conducted subsurface exploration to evaluate the collapse
potential of the non -irrigated debris fan areas within the development, report dated
September 10, 1998, Job No. 197 327, and have conducted subsurface exploration for
evaluation of subsidence potential on Lot 133 that will be reported under separate cover.
An exploratory boring was drilled on the lot to obtain information on the subsurface
conditions. Samples of the subsoils obtained during the field exploration were tested in
the laboratory to determine their classification, compressibility or swell and other
engineering characteristics. The results of the field exploration and laboratory testing
were analyzed to develop recommendations for foundation types, depths and allowable
pressures for the proposed building foundation. This report summarizes the data obtained
during this study and presents our conclusions, design recommendations and other
geotechnical engineering considerations based on the proposed construction and the
subsurface conditions encountered.
PROPOSED CONSTRUCTION
The specific building on the lot had not been determined at the time of this study. The
proposed residence will generally be a I or 2 story, wood frame structure between about
2,500 and 3,000 square -feet in size. Ground floor will be slab -on -grade and/or structural
over a crawlspace. A basement level may be provided. Grading for the structure is
assumed to be relatively minor with cut depths between about 3 to 8 feet. We assume
relatively light foundation loadings, typical of the proposed type of construction.
Job No. 101 196-1
-2 -
If building loadings, location or grading plans change significantly from those described
above, we should be notified to re-evaluate the recommendations contained in this report.
SITE CONDITIONS
The lot is located in the south-central part of the development and was vacant at the time
of our field exploration. Silver Mountain Drive borders -the lot to the east as shown on
Figure 1. The roadway and underground utility construction to the lot are complete.
Minor overlot grading during subdivision development consists of shallow cuts and fills
on the lot. The ground surface is relatively flat and slopes gently to strongly down to the
east. The drainage ditch along Silver Mountain Drive and spring thaw made the drill rig
access difficult and delayed the exploratory drilling.
GEOLOGY
The geologic conditions were described in our previous report conducted for planning and
preliminary design of the subdivision development, dated October 29, 1997, Job No. 197
327. The surficial soils on the lot mainly consist of sandy silt and clay debris fan deposits
overlying terrace gravel alluvium of the Roaring Fork River at a depth of 41'/2 feet. The
alluvium is predominantly a clast-supported deposit of rounded gravel, cobbles and
boulders up to 3 feet in size in a silty sand matrix that extended to a depth of 52 feet on
the lot.
The underlying bedrock consists of the Eagle Valley Evaporite which contains gypsum
and is generally associated with scattered sinkhole development in the Roaring Fork
River valley. Voids were not encountered in the bedrock to the drilled depth of 78 feet
and the potential for subsidence due to dissolution of the evaporite throughout the service
life of the residence, in our opinion, is low. Our project report to be issued under separate
cover should be referenced for the complete findings of the subsidence potential
evaluation.
Job No. 101 196-1
-3 -
FIELD EXPLORATION
The field exploration for the project was conducted on March 18, 2005. An exploratory
boring was drilled at the location shown on Figure 1 to evaluate the subsurface
conditions. The boring was advanced with 4 -inch diameter continuous flight augers
powered by a truck -mounted CME -45B drill rig. The boring was logged by a
representative of Hepworth-Pawlak Geotechnical, Inc.
Samples of the subsoils were taken with a 2 inch I.D. spoon sampler. The sampler was
driven into the subsoils at various depths with blows from a 140 pound hammer falling 30
inches. This test is similar to the standard penetration test described by ASTM Method
D-1586. The penetration resistance values are an indication of the relative density or
consistency of the subsoils. Depths at which the samples were taken and the penetration
resistance values are shown on the Log of Exploratory Boring, Figure 2. The samples
were returned to our laboratory for review by the project engineer and testing.
SUBSURFACE CONDITIONS
A graphic log of the subsoil profile encountered in the boring is shown on Figure 2. The
subsoils, below about'/: foot of topsoil, consist of 411/4 feet of generally stiff, sandy silt
and clay overlying relatively dense, silty sandy gravel and cobbles with boulders (terrace
alluvium) down to the drilled depth of 471/4 feet. Drilling in the terrace alluvium with
auger equipment was difficult due to the cobbles and boulders and practical refusal to
drilling was encountered in the deposit.
Laboratory testing performed on samples obtained from the boring included natural
moisture content and density, and percent finer than No. 200 sieve (silt and clay fraction)
gradation analysis. Results of swell -consolidation testing performed on relatively
undisturbed drive samples, presented on Figure 4, indicate low compressibility under
existing low moisture content and light loading and a low collapse potential (settlement
Job No. 101 196-1
-4 -
under a constant load) when wetted. The samples showed moderate compressibility with
increased loading after wetting. The laboratory testing is summarized in Table 1.
No free water was encountered in the boring at the time of drilling and the subsoils were
slightly moist.
FOUNDATION BEARING CONDITIONS
The upper silt and clay (debris fan) soils typically have low bearing capacity and low to
moderate settlement potential. Foundations which extend down to the dense terrace
alluvium would have moderate bearing capacity and low settlement risk. Spread footings
placed on the upper debris fan soils should be suitable for support of lightly loaded
structures with some settlement risk, mainly if the bearing soils become wetted. The
settlement potential and risk of distress can be reduced by supporting the building on a
stiffened slab (mat) foundation, or ground improvements, such as removal and
replacement of the native soils compacted to at least 95% of standard Proctor density at a
moisture content at to 2% above optimum. We expect the ground modifications would be
limited to the upper 5 to 10 feet. If a mat foundation or ground improvements are
proposed, we should be contacted.
DESIGN RECOMMENDATIONS
FOUNDATIONS
Considering the subsurface conditions encountered in the exploratory boring and the
nature of the proposed construction, we recommend the building be founded with spread
footings bearing on the natural subsoils.
The design and construction criteria presented below should be observed for a spread
footing foundation system.
1) Footings placed on the undisturbed natural subsoils should be designed for
an allowable bearing pressure of 1,200 psf. Based on experience, we
Job No. 101 196-1
-5 -
expect initial settlement of footings designed and constructed as discussed
in this section will be up to about 1 inch. Due to the variable settlement
potential of the debris fan soils, additional differential movement of about
1 to 2 inches could occur if the bearing soils become wetted.
2) The footings should have a minimum width of 20 inches for continuous
walls and 2 feet for isolated pads.
3) Exterior footings and footings beneath unheated areas should be provided
with adequate soil cover above their bearing elevation for frost protection.
Placement of foundations at least 36 inches below exterior grade is
typically used in this area.
4) Continuous foundation walls should be reinforced top and bottom to span
local anomalies such as by assuming an unsupported length of at least 12
feet. Foundation walls acting as retaining structures should also be
designed to resist lateral earth pressures as discussed in the "Foundation
and Retaining Walls" section of this report.
5) The topsoil, any existing fill and loose or disturbed soils should be
removed and the footing bearing level extended down to the firm natural
soils. The exposed soils in footing area should then be moistened and
compacted.
6) A representative of the geotechnical engineer should observe all footing
excavations prior to concrete placement to evaluate bearing conditions.
FOUNDATION AND RETAINING WALLS
Foundation walls and retaining structures which are laterally supported and can be
expected to undergo only a slight amount of deflection should be designed for a lateral
earth pressure computed on the basis of an equivalent fluid unit weight of at least 55 pcf
for backfill consisting of the on-site fine-grained soils. Cantilevered retaining structures
which are separate from the building and can be expected to deflect sufficiently to
mobilize the full active earth pressure condition should be designed for a lateral earth
pressure computed on the basis of an equivalent fluid unit weight of at least 50 pcf for
backfill consisting of the on-site fine-grained soils.

FLOOR SLABS
The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded slab -
on -grade construction. The debris fan soils are typically compressible when wetted under
load and there could be some post -construction slab settlement and distress if the
subgrade soils become wet. To reduce the effects of some differential movement, floor
slabs should be separated from all bearing walls and columns with expansion joints which
allow unrestrained vertical movement. Floor slab control joints should be used to reduce
damage due to shrinkage cracking. The requirements for joint spacing and slab
reinforcement should be established by the designer based on experience and the intended
slab use. A minimum 4 inch layer of free -draining gravel should be placed beneath
basement level slabs to facilitate drainage. This material should consist of minus 2 inch
aggregate with at least 50% retained on the No. 4 sieve and less than 2% passing the No.
200 sieve.
All fill materials for support of floor slabs should be compactedxo at least 95% of
maximum standard Proctor density at a moisture content near optimum. Required fill can
consist of the on-site soils devoid of vegetation, topsoil and oversized rock.
UNDERDRAIN SYSTEM
Although free water was not encountered during our exploration, it has been our
experience in the area that local perched groundwater can develop during times of heavy
precipitation or seasonal runoff. Frozen ground during spring runoff can create a perched
condition. We recommend below -grade construction, such as retaining walls, crawlspace
and basement areas, be protected from wetting and hydrostatic pressure buildup by an
underdrain system. An underdrain should not be provided around shallow foundations (3
feet deep or less) and garage areas.
The drains should consist of drainpipe placed in the bottom of the wall backfill
surrounded above the invert level with free -draining granular material. The drain should
be placed at each level of excavation and at least 1 foot below lowest adjacent finish
Job No. 101 196-1
-8 -
grade and sloped at a minimum 1% to a suitable gravity outlet. Free -draining granular
material used in the underdrain system should contain less than 2% passing the No. 200
sieve, less than 50% passing the No. 4 sieve and have a maximum size of 2 inches. The
drain gravel backfill should be at least 11/4 feet deep. An impervious membrane such as
20 mil PVC should be placed beneath the drain gravel in a trough shape and attached to
the foundation wall with mastic to prevent wetting of the bearing soils.
SURFACE DRAINAGE
The following drainage precautions should be observed during construction and
maintained at all times after the building has been completed:
1) Inundation of the foundation excavations and underslab areas should be
avoided during construction.
2) Exterior backfill should be adjusted to near optimum moisture and-.
compacted to at least 95% of the maximum standard Proctor density in
pavement and slab areas and to at least 90% of the maximum standard
Proctor density in landscape areas.
3) The ground surface surrounding the exterior of the building should be
sloped to drain away from the foundation in all directions. We
recommend a minimum slope of 6 inches in the first 10 feet in unpaved
areas and a minimum slope of 3 inches in the first 10 feet in paved areas.
Free -draining wall backfill should be capped with about 2 feet of the on-
site, fine-grained soils to reduce surface water infiltration.
4) Roof downspouts and drains should discharge well beyond the limits of all
backfill.
5) Landscaping which requires regular heavy irrigation should be located at
least 10 feet from foundation walls. Consideration should be given to use
of xeriscape to reduce the potential for wetting of soils below the building
caused by irrigation.

LIMITATIONS
This study has been conducted in accordance with generally accepted geotechnical
engineering principles and practices in this area at this time. We make no warranty either
express or implied. The conclusions and recommendations submitted in this report are
based upon the data obtained from the exploratory boring drilled at the location indicated
on Figure 1, the proposed -type of construction and ourexperience in the area. Our
services do not include determining the presence, prevention or possibility of mold or
other biological contaminants (MOBC) developing in the future. If the client is
concerned about MOBC, then a professional in this special field of practice should be
consulted. Our findings include interpolation and extrapolation of the subsurface
conditions identified at the exploratory boring and variations in the subsurface conditions
may not become evident until excavation is performed. If conditions encountered during
construction appear different from those described in this report, we should be notified so
that re-evaluation of the recommendations may be made.
This report has been prepared for the exclusive use by our client for design purposes. We
are not responsible for technical interpretations by others of our information. As the
project evolves, we should provide continued consultation and field services during
construction to review and monitor the implementation of our recommendations, and to
verify that the recommendations have been appropriately interpreted. Significant design
changes may require additional analysis or modifications to the recommendations
presented herein. We recommend on-site observation of excavations and foundation
bearing strata and testing of structural fill by a representative of the geotechnical
engineer.
