Subject: Subsoil Study for Foundation Design and Percolation Testing, Proposed
Residence, Lot 30, Horse Pasture, Gypsum, Colorado
aAr-cr_- '�' 2-el,
Dear Ms. Bishop:
As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study and
percolation testing for foundation and septic disposal system designs at the subject site.
The study was conducted in accordance with our agreement for geotechnical
engineering services to Design Development dated January 7, 1997. 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 a single story wood frame
structure over a garden level basement located on the site as shown on Fig. 1. Basement
and garage floors will be slab -on -grade. Cut depths are expected to be up to about 6
feet. Foundation loadings for this type of construction are assumed to be relatively
light.
If building conditions or foundation loadings are significantly different from those
described above, we should be notified to reevaluate the recommendations presented in
this report.
Site Conditions: The site was vacant and covered with about 6 inches of snow at the
time of our field work. The lot is in a relatively flat irrigated pasture with a gentle
slope down to the west and about 2 feet of elevation difference across building area. A
dry irrigation ditch is located about 120 feet to the west and downhill of the proposed
building. Vegetation consists of grasses and weeds beneath the snow.
Subsurface Conditions: The subsurface conditions at the site were evaluated by
excavating one exploratory pit in the building area and a 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 11/2 to 2 feet of topsoil,
consist of loose to medium dense silty sand. Results of swell -consolidation testing
performed -on a re ative y undisturbed sample of the silty sand, presented on Fig. 3,
indicate low compressibility under existing moisture conditions and light loading and a
low collapse potential (settlement under constant load) when wetted. The sample
showed moderate compressibility upon additional loading after wetting. No free water
was observed in the pits at the time of excavation and the soils were moist.
Design Development
February 4, 1997
Page 2
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 soil designed for an allowable soil bearing
pressure of 1,000 psf for support of the proposed residence. The soils are collapsible
and tend to compress after wetting and there could be some post -construction settlement
particularly if the bearing soils become wetted. Footings should be a minimum width
of 18 inches for continuous walls and 2 feet for columns. Loose and disturbed soils
encountered at the foundation bearing level within the excavations should be removed
and the footing subgrade moistened and compacted to help limit settlement potential.
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 heavily reinforced
top and bottom to span local anomalies and limit the effects of potential differential,
settlement 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 45 pcf for the on -site soil as backfill,
Floor Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support
lightly loaded slab -on -grade construction. The silty sand soils encountered tend to
collapse when wetted, which could result in slab distress. 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 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 and topsoil.
Underdrain System: Although free water was not encountered during our exploration,
it has been our experience that local perched groundwater may 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.
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. 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
H-P GEOTECH
Design Development
February 4, 1997
Page 3
2 inches. The drain gravel backfill should be at least 11/z 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. Free draining wall backfill should be
capped will 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.
4) Roof downspouts and drains should discharge well beyond the limits of
all backfill.
5) Landscaping which requires regular heavy irrigation such as sod should
be located at least 10 feet from the building. Consideration should be
given to the use of xeriscape to help limit the risk of wetting the bearing
soils.
Percolation Testing: The results of percolation tests conducted at the site are presented
in Table Il. The test locations are shown on Fig. 1 and the log of the profile is shown
on Fig. 2. The subsoil profile in the proposed septic disposal area consists of 2 feet of
topsoil overlying silty sand down to the maximum depth explored, 10 feet. The
percolation test holes were hand dug at the bottom of shallow backhoe pits on January
20, 1997. The tests holes were protected from freezing overnight with rigid foam
insulation. The percolation tests were performed on January 21, 1997. At the time of
the tests, the soil temperature was between 40' F and 43' F and no frost was observed
in the test hole soils. The percolation rate was aboutinutes per inch in all three
holes. Based on the relatively fast percolation rates measured, it is our understanding
the Eagle County will require the system be designed by a civil engineer.
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 locations indicated on Fig. 1, the proposed type of construction, and
our experience in -the area. Our findings include interpolation and extrapolation of the
H-P GEOTECH
Design Development
February 4, 1997
Page 4
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 geotechnical
engineer.
If you have any questions or if we may be of further assistance, please call our office.
