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

TABLE 1- SUMMARY OF LABORATORY TEST RESULTS
PURPOSE AND SCOPE OF STUDY
This report presents the results of a subsoil study for a proposed residence to be located
on Lot 105, Ironbridge Development, River Bend Way, 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 for the non -irrigated debris fan areas within the development and presented our
findings in a report dated September 10, 1998, Job No. 197 327.
An exploratory boring was drilled near the center of the lot to obtain information on the
general 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 plan for the lot had not been determined at the time of our study.
The proposed residence will generally be a one and two 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 above crawlspace. A partial basement level may be provided. Grading
for the structure is assumed to be relatively minor with cut depths between about 3 to 6
feet. We assume relatively Tight foundation loadings, typical of the proposed type of
construction.
JobNo 101196-1
GeStech
-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 southern part of the development and was vacant at the time of
our field exploration. The lot is bordered by River Bend Way to the southeast and by the
16`h Fairway to the northwest as shown on Figure 1. The roadway and underground
utility construction to the lot are complete. Shallow cuts and fills were observed on the
lot from minor overlot grading as part of the subdivision development. The ground
surface is relatively flat with a gentle slope down to the northeast. There is about 2 feet
of elevation difference across the building area. The native vegetation had been stripped
during the previous overlot grading.
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 alluvial fan
deposits overlying terrace gravel alluvium of the Roaring Fork River. The alluvium is
predominantly a clast-supported deposit of rounded gravel, cobbles and boulders up to
about 3 feet in sized in a sand and silty sand matrix.
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. The potential for subsidence due to dissolution of the evaporite throughout
the service life of the residence, in our opinion, is low. If further evaluation of the
sinkhole potential on the lot is desired, we should be contacted.

FIELD EXPLORATION
The field exploration for the project was conducted on October 1, 2004. One 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 1 inch and 2 inch I.D. spoon samplers. The
samplers were 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 retumed to our laboratory for review by the project engineer and
testing.
SUBSURFACE CONDITIONS
A graphic log of the subsurface conditions encountered at the site is shown on Figure 2.
The subsoils consist of about I foot of granular fill overlying stiff to very stiff, sandy silt
and clay. Relatively dense, silty sandy gravel with cobbles and boulders was encountered
beneath the silt and clay at a depth of 13 feet. Drilling in the dense granular soils with
auger equipment was difficult due to the cobbles and boulders and drilling refusal was
encountered in the deposit.
Laboratory testing performed on samples obtained from the boring included natural
moisture content, density and finer than sand size gradation analysis. Results of swell -
consolidation testing performed on a relatively undisturbed drive sample of clay,
presented on Figure 4, indicate low to moderate compressibility under conditions of
loading and wetting. The laboratory testing is summarized in Table 1.
Job No 101 196-1
Glertech
-4 -
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 soils typically have low bearing capacity and low to moderate
settlement potential. Foundations which extend down to the dense gravel alluvium would
have moderate bearing capacity and relatively low settlement risk. Spread footings
bearing on the upper silt and clay soils should be suitable for support of relatively lightly
loaded structures with some settlement risk, mainly if the bearing soils become wetted. If
a deep foundation is 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 1,500 psf. Based on experience, we
expect initial settlement of footings designed and constructed as discussed
in this section will be less than 1 inch. Due to the variable
settlement/heave potential of the upper silt and clay soils, additional
differential movement of about 1 inch could occur if the bearing soils
become wetted.
Job No 101 196-1
G tech
-5-
2) The footings should have a minimum width of 18 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 existing fill and any loose disturbed soils should be removed and the
footing bearing level extended down to the undisturbed 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 residence 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.
All foundation and retaining structures should be designed for appropriate hydrostatic and
surcharge pressures such as adjacent footings, traffic, construction materials and
equipment. The pressures recommended above assume drained conditions behind the

walls and a horizontal backfill surface. The buildup of water behind a wall or an upward
sloping backfill surface will increase the lateral pressure imposed on a foundation wall or
retaining structure. An underdrain should be provided to prevent hydrostatic pressure
buildup behind walls.
Backfill should be placed in uniform lifts and compacted to at least 90% of the maximum
standard Proctor density at a moisture content near optimum. Backfill in pavement and
walkway areas should be compacted to at least 95% of the maximum standard Proctor
density. Care should be taken not to overcompact the backfill or use large equipment
near the wall, since this could cause excessive lateral pressure on the wall. Some
settlement of deep foundation wall backfill should be expected, even if the material is
placed correctly, and could result in distress to facilities constructed on the backfill.
The lateral resistance of foundation or retaining wall footings will be a combination of the
sliding resistance of the footing on the foundation materials and passive earth pressure
against the side of the footing. Resistance to sliding at the bottoms of the footings can be
calculated based on a coefficient of friction of 0.35. Passive pressure of compacted
backfill against the sides of the footings can be calculated using an equivalent fluid unit
weight of 300 pcf. The coefficient of friction and passive pressure values recommended
above assume ultimate soil strength. Suitable factors of safety should be included in the
design to limit the strain which will occur at the ultimate strength, particularly in the case
of passive resistance. Fill placed against the sides of the footings to resist lateral loads
should be compacted to at least 95% of the maximum standard Proctor density at a
moisture content near optimum.
FLOOR SLABS
The natural on-site soils, exclusive of topsoil, are suitable to support lightly loaded slab -
on -grade construction. The upper silt and clay 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,
Sob No. 101 196-1

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.
Al] fill materials for support of floor slabs should be compacted to 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.
UNDERDRAJN 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 and
basement areas, be protected from wetting and hydrostatic pressure buildup by an
underdrain system. An underdrain should not be provided around shallow foundations
such as crawlspace 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
grade and sloped at a minimum 1% to a suitable gravity outlet or sump and pump. 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 11/2 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 residence 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) Irrigation sprinkler heads and landscaping which requires regular heavy
irrigation, such as sod, should be located at least 5 feet from foundation
walls.
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 our experience 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 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.
