Subject: Subsoil Study for Foundation Design, Proposed Residence,
Hardscrabble Mountain Road, 4 Miles South of Gypsum, Colorado.
Dear Mr. Forsyth,
As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study for
design of foundations at the subject site. The study was conducted in accordance with
our agreement for geotechnical engineering services to Roby Forsyth dated August 16,
1993. The data obtained and our recommendations based on the proposed
construction and subsurface conditions encountered are presented in this report.
Proposed Construction: The proposed residence will be single story above a walkout
basement level. Ground floor will be slab -on -grade. Cut depths are expected to
range between about 3 to 6 feet. Foundation loadings for this type of construction are
assumed to be relatively light.
If wilding conditions or foundation loadings are significantly different from those
de;.cribed above, we should be notified to reevaluate the recommendations presented
in this: report.
Site: Conditions: The site consists of vacant property just south of an existing barn.
The, ground surface in the area of the building site was mainly undisturbed and
covered with grass, weeds, and some sagebrush. The building excavation was partly
ditto a depth of about 5 1/2 feet at the uphill (east) corner. The ground surface slope
is relatively gentle down to the west. Irrigated hay fields are located just south and
east of, the building site.
Subsurface Conditions: The subsurface conditions at the site were evaluated by
observing two exploratory pits which had been dug prior to our site visit. The logs of
tht pits are presented on Fig. 1. Pit 1 is located downhill in the proposed leach field
ago and Pit 2 is located just uphill of the building site. The subsoils encountered in
pits exposed in the excavation consist of about 2 to 4 feet of relatively loose
govelly silt and sand above silty sandy gravel with cobbles. The coarse rock is
nuinly subangular red sandstone fragments. Results of consolidation testing
peformed on a relatively undisturbed sample of the silty sand, presented on Fig. 2,
tdicate low compressibility under existing moisture conditions and light loading and a
ligh collapse potential when wetted. Results of a gradation analysis performed on a
Swnple;, of clayey gravel (minus 5-inch fraction) obtained from the site are presented
M Fig. 3. No free water was observed in the pits and the soils were typically slightly
nvistt .

Foundation Recommendations: Considering the subsoil conditions encountered in
the exploratory pits and the nature of the proposed construction, spread footings
placed on the undisturbed natural soil could be used for support of the residence with
some risk of differential settlement. The soils are relatively loose and wetting could
cause localized settlement and distress. Placing the footings below the upper sandy
layer will reduce the settlement risk. Footings can be designed for an allowable soil
bearing pressure of 1000 psf and should have a minimum width of 18 inches for
continuous walls and 2 feet for columns. Loose and disturbed soils and the loose sand
encountered at the foundation bearing level within the excavation should be removed
and the footing bearing level deepened or the material should be moistened and
compacted. Exterior footings should be provided with adequate cover above their
bearing elevations for frost protection. Placement of footings at least 42 inches below
the exterior grade is typically used in this area. Continuous foundation walls should
be reinforced top and bottom to span local anomalies such as by assuming an
unsupported length of at least 14 feet. Foundation walls acting as retaining structures
should be designed to resist a lateral earth pressure based on an equivalent fluid unit
weight of at least 40 pcf for the on -site soil as backfill excluding oversized rock.
Flo" Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support
lightly, loaded slab -on -grade construction. There is a risk of floor slab settlement due
to vixtting of the upper sandy soils. 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,oint 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 less than 50 % passing 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 95 % of
maximum standard Proctor density at a moisture content near optimum. Required fill
canconsist of the on -site soils devoid of vegetation, topsoil and oversized rock.
Unrdrain System: Although free water was not encountered during our
ex#i;oration, it has been our experience in the area that local perched groundwater may
dexelop during times of heavy precipitation or seasonal runoff. Frozen ground during
sp�ng runoff can create a perched condition. We recommend below grade
.crostruction, such as retaining walls, crawl space and basement areas, be protected
fran wetting and hydrostatic pressure buildup by an underdrain system
H74 G'EOTECH
Roby Forsyth

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 least 1 foot below the basement floor level and sloped at a
minimum 1 % to a suitable gravity outlet. The walkout side of the basement should
not need a foundation drain. 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 2 feet deep. An impervious liner such as 20 mil PVC should be
placed below 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 slab and walkway
areas and to at least 90 % of the maximum standard Proctor density in
landscape areas. Free -draining wall backfill should be capped with at least 2
feet of the on -site, finer graded soils to reduce surface water infiltration.
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 pavement and walkway areas.
A swale will be needed uphill to direct surface runoff around the residence.
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 the building.
Percolation Tests: Percolation tests were conducted in three hand dug holes between
;40 and 47 inches deep adjacent the west side of the existing barn and

infiltration septic disposal system. A percolation rate of 20 minutes per inch can be
used for the leach field area sizing.
Limitations: This report has been prepared in accordance with generally accepted
geotechnical engineering principles and practices in this area at this time. We make
no other warranty either expressed or implied. The conclusions and recommendations
submitted in this report are based upon the data obtained from the exploratory pits
excavated at the indicated locations, the proposed type of construction and our
experience in the area. Our findings include interpolation and extrapolation of the
subsurface conditions identified at the exploratory pits 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 at once so 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
soil engineer.
If you have any questions or if we may be of further assistance, please call our office.

Mr. and Mrs. Roby Forsyth plan to build a four bedroom, 3 bath home
and use an infiltrator system. The system will consist of two
trenches three feet by one hundred feet long allowing six feet
between each trench. A 1500 gallon, two -compartment plastic tank
with two inspection holes within eight inches of ground level will
also be used to complete the system. The percolation rate is 1
inch in twenty minutes. Enclosed is a copy of the soil and
percolation tests.
