Subject: Subsoil Study for Foundation Design and Percolation Test, Proposed
Garage/Barn, Lot 5, Spring Park Ranches, Eagle County, Colorado
Dear Mr. Janckila:
As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study and
percolation test for foundation and septic disposal designs at the subject site. The study
was conducted in accordance with our agreement for geotechnical engineering services
to Jensen Homes dated March 25, 1999. The data obtained and our recommendations
based on the proposed construction and subsurface conditions encountered are presented
in this report.
Proposed Construction: The proposed garage/barn will be a two story wood frame
structure located on the site as shown on Fig. 1. Ground floor is proposed to be a dirt
barn on the lower level. A portion will have slab -on -grade for office. Cut depths are
expected to range between about 3 to 5 feet. Foundation loadings for this type of
construction are assumed to be relatively light and typical of the proposed tyre of
construction. The septic disposal system is proposed to be located about 175 feet to the
southwest of the proposed residence.
If building conditions or foundation loadings are significantly different from those
described above, we should be notified to re-evaluate the recommendations l'resented in
this report.
Site Conditions: The site was vacant at the time of our field work. The ground
surface in the building area is relatively flat with a moderate slope down to the
southwest at grades up to about 10%. There is about 4 to 6 feet elevation diference
across the building area. The Monarch Ditch is located about 60 feet downhill to the
southeast of the proposed building. The lot is vegetated with scruboak, sagebrush,
grass and weeds.
Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating one exploratory pit in the building area and one profile pit in the septic
disposal area at the approximate locations shown on Fig. 1. The logs of the pits are
presented on Fig. 2. The subsoils encountered, below about 21/2 feet of topsoil and 1 to
11/2 feet of clay and gravel consist of relatively dense slightly silty sandy gravel with
Jensen Homes
April 20, 1999
Page 2
cobbles and boulders. Results of a gradation analyses performed on samples of the
gravels (minus 5 inch fraction) obtained from the site are presented on Fig. 3. No free
water was observed in the pits at the time of excavation and the soils were slightly moist
to moist.
Foundation Recommendations: Considering the subsoil conditions encountered in the
exploratory pits and the nature of the proposed construction, we recommend spread
footings placed on the undisturbed natural gravels designed for an allowable soil bearing
pressure of 3,000 psf for support of the proposed residence. Footings should be a
minimum width of 16 inches for continuous walls and 2 feet for columns. Loose and
disturbed soils encountered at the foundation bearing level within the excavation should
be removed and the footing bearing level extended down to the undisturbed natural
gravels. Exterior footings should be provided with adequate cover above thir 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 10 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 45 pef for the on -site gravels, exclusive of oversized rock, as backfill.
Floor Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support
lightly loaded slab -on -grade construction. 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 slabs -on -grade to facilitate drainage and act as a leveling
course. 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
can consist of the on -site soils devoid of vegetation, topsoil and oversized rock.
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
H-P GEOTECH
Jensen Homes
April20, 1999
Page 3
pavement and slab areas and to at least 90 % of the maximum standard
Proctor density in landscape areas. Free -draining wall backfill should be
capped with about 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 12 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.
4) Roof downspouts and drains should discharge well beyond the limits of
all backfill.
Percolation Testing: Percolation tests were conducted on March 26, 1999 to evaluate
the feasibility of an infiltration septic disposal system at the site. One profile pit and
three percolation holes were dug at the locations shown on Fig. 1. The test 11oles
(nominal 12 inch diameter by 12 inch deep) were hand dug at the bottom of shallow
backhoe pits and were soaked with water one day prior to testing. The soils exposed in
the percolation holes are similar to those exposed in the Profile Pit shown on Fig. 2 and
consist of about 21/2 feet of topsoil and 1'/2 feet of clay and gravel overlying dense
sandy gravel with cobbles and boulders. The percolation test results are presented in
Table I. The percolation test results indicated an infiltration rate between 60 and 180
minutes per inch with an average of 110 minutes per inch. The tests were conducted in
the clay and gravel soils. Due to the relatively slow percolation rate, the percolation
holes were deepened and additional percolation tests were conducted in the underlying -
sandy gravels on April 6, 1999. The additional tests did not percolate. Eagle County
may require that a civil engineer design the infiltration septic disposal system.
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 expressed or implied. The conclusions and recommendations submitted
in this report are based upon the data obtained from the exploratory pits excavated at the
locations indicated on Fig. 1, 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
H-P GEOTECH
Jensen Homes

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.
If you have any questions or if we may be of further assistance, please let us know.
