And
MOVED BUILDINGS
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
construction of your project. Any project with more than ten (10) occupants requires the plans
to be sealed by a Colorado Registered Design Professional.
To provide for a more understandable plan in order to determine compliance with the building,
plumbing and mechanical codes, applicants are requested to review the following checklist prior to
and during design. Applicants are required to indicate appropriately and to submit the
completed checklist at time of application for a permit.

PURPOSE AND SCOPE OF STUDY
This report presents the results of a subsoil study fol a proposed residence to be located
on Lot 98, River Bend Way, 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.H. Rose Ranch, LLC dated July
24, 2003. We previously performed a preliminary subsoil study for Lots 90 through 100
and presented our findings in a report dated December 31, 2002, lob No. I01 196-1
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 1 or 2 story. wood frame stricture about 2,500 to
3,000 square -feet in size. Ground floor will be slab -on -grade and/or structural over a
crawispace. 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.
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
9513465087 p.6
The lot is located in the downhill, eastern part of the development and was vacant at the
time of our field exploration. River Bend Way borders the lot to the northeast and the
Robertson Ditch (in a culvert) and golf course border the lot to the west as shown 011
Figure I . The roadway and underground utility construction to the lot are complete. The
residence on Lot 100 is under construction. Minor overlot grading during subdivision
development consists of shallow cuts and fills across most of the lot. The ground surface
is relatively flat and slopes gently down to the northeast.
GEOLOGY
The geologic conditions were described in aur 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 consist mainly of sandy silty day (debris 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 3
feet in size 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 July 14, 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
Cob No. 101 196-1
Rug 29 2005 11:47
IROMBRIDGE HOMES LLC 9513465087
powered by a truck -mounted CME -4514 drill rig. the boring was logged by a
representative ofHepworth-Pawlak Geotcclmical, Inc.
Samples of the subsoils were taken with 1 3/8 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 desci ibed
by ASTM Method D -I 586. 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 holing is shown on Figure 2. The
subsoils, below about % foot of topsoil, consist of 4 feet of very stiff, sandy silty clay
overlying relatively dense, silty sandy gravel and cobbles with boulders (terrace alluvium)
down to the drilled depth of 11 feet. Drilling in the dense terrace alluvium 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 and density. Results of swell -consolidation testing performed on a
relatively undisturbed drive sample of the upper clay soil, presented on Figure 4, indicate
low compressibility under existing low moisture conditions and light loading and a low
collapse potential (settlement under constant load) after wetting. The sample showed
moderate compressibility ander addition] load after welting.
No free water was encountered in the boring at the lime drilling and the subsoils were
slightly moist. Groundwater was encountered at a depth of about 12 feet on Lot 100 and
at about 13 feet on Lot 90, located to the south and north of Lot 98, respectively.

FOUNDATION REARING CONDITIONS
The upper silty clay (debris fan) soils typically have low bearing capacity and low to
moderate settlement potential under loading when wetted. Foundations which extend
down to the dense terrace alluvium would have moderate bearing capacity and low
settlement risk. Spread footings placed on the natural soils should be feasible for building
support with some potential for differential settlement. mainly if the debris fan soils are
wetted.
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. Footings bearing entirely on
the dense terrace alluvium can be designed for an allowable bearing
pressure of 3,000 psf. Based on experience, we expect initial settlement of
footings designed and constructed as discussed in this section will be about
1 inch or less. Due to the variable settlement potential of the debris fan
soils, additional differential movement on the order of ii inch could occur,
mainly if' the debris fan soils are wetted.
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 he assuming an unsupported length of at least 12
feet. Foundation walls acting as lemming structures should also he
designed to resist lateral earth pressures as discussed in the "Foundation
and Retaining Walls" section of this report.
51 Any existing fill, topsoil 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 structwes 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 clay soils. Cantilevered retaining structures which
are separate from the residence and can be expected to deflect sufficiently to mobilize tite
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 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 asswne 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 sntucture. An underdrain should he provided to prevent hydrostatic pressure
buildup behind walls.

Backfill should be placed in uniform lifts and compacted to at least 90% of the ntaxiniuni
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
densly Care should be taken not to overcompact the backfill or use large equipment
nem the wall, since this could cause excessive lateral pressure on the wall. Some
settlement of deep foundation wall backfill should he 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 for footings placed on the silty clay
soils and 0.50 for footings placed on gravel sods. Passive pressure of compacted backfill
against the sides of the footings can be calculated using an equivalent fluid unit weight of
350 pcf. The coefficient of friction and passive pressure values recommended above
assume ultnnate 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 silty clay soils have variable settlement potential when
wetted under load and there could be some post -construction slab movement if the
subgradc 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 Tree -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 compacted to at least 95u/0 of
maximum standard Proctor density at a moisture content near optimum. Required fill can
consist of the on-site gravel terrace soils devoid of vegetation, topsoil and oversized rock.
UNDERDRAMNSYSTEM
Although free water was not encountered during our exploration, it has been out
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. The basement floor should be kept relatively shallow to reduce the potential for
groundwater impacts. 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 end at least 1 foot below lowest adjacent finish
grade and sloped at a minimum I% to a suitable gravity outlet. Free -draining granular
material used in the underdrain system should contain less than 2% passing the No. 290
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. Where footings bear on the upper
silty clay soils, an impervious membrane such as a 20 mil PVC liner should be placed in a
trough shape below the drain gravel and attached to the foundation wall with mastic to

prevent wetting of the bearing soils.
SURI'ACE DRAINAGE
9513465087 p.12
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 neat optimum mutstute 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 he
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 teduce 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 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. \Ve 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 of

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 he notified so
that re-evaluation of the recommendations may he 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 OUT 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 recouunend on-site observation of excavations and foundation
hearing strata and testing of structural fill by a representative of the geotechnical
engineer.
