Subject: Observation of Pit Excavations and Percolation Testing, Proposed
Residence, North of Pond, Lyons Ranch, County Road 300, Parachute,
Colorado
Dear Mr. Lyons:
As requested, a representative of Hepworth - Pawlak Geotechnical, Inc. observed the pit
excavations at the subject site on August 2, 1996 to evaluate the soils exposed for
foundation support. The findings of our work and recommendations for the foundation
design are presented in this report. The work was done in accordance with our
agreement for gebtechnical engineering services to you, dated July 31, 1996.
Additional percolation testing was performed as requested by Greg Newton.
Site and Subsoil Conditions: The proposed residence will be located just north of the
pond and will consist of a one story wood frame structure over a full basement level.
The basement floor will be slab -on- grade.
At the time of our visit to the site, two exploratory pits had been excavated to depths of
8 to 10 feet in the proposed building area. The soils exposed in the exploratory pits
consisted of slightly silty sandy gravel with cobbles. The results of a gradation analysis
performed on a sample of the gravel (minus 3 inch fraction) obtained from the building
site are presented on Fig. 1. The laboratory testing is summarized on Table I. No free
water was encountered in the pit excavations and the soils were slightly moist to moist.
Foundation Recommendations: Considering the conditions exposed in the pit
excavations and the nature of the proposed construction, spread footings placed on the
undisturbed natural gravels designed for an allowable soil bearing pressure of 3,000 psf
should be adequate 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 to expose the undisturbed natural soils. Exterior footings should be
provided with adequate soil cover above their bearing elevations for frost protection.
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 40 pcf for on -site gravel soil as
backfill (minus 6 inch fraction). A perimeter foundation drain should be provided to
prevent temporary buildup of hydrostatic pressure behind the walls and prevent wetting
of the lower level. The perimeter drain should consist of perforated pipe surrounded
above the invert level with 11/2 feet of screened rock. The drain should be sloped at
1% grade to a suitable gravity outlet. Structural fill placed within floor slab areas can
consist of the on -site soils compacted to at least 95% of standard Proctor density at a
moisture content near optimum. Backfill placed around the structure should be
compacted and the surface graded to prevent ponding within at least 10 feet of the

building.
Percolation Testing: Percolation testing was performed in test holes excavated and
soaked by the ranch manager, Greg Newton. Initial testing performed on August 3,
1996 included a site on the fill bench west of the pond and two sites northwest of the
residence on the lower area near the county road. Due to the slow percolation rates
encountered in these areas, two other areas were evaluated. Additional percolation
testing was performed on August 7, 1996 in an area just west of the residence on the
upper gravel bench and on the lower area near the toe of the slope. The percolation
tests were performed in hand dug 1 foot diameter holes at the bottom of 2 to 3 foot
deep backhoe pits. The percolation holes were excavated and soaked on August 6,
1996. The tests were performed on August 7, 1996. A profile pit was excavated at
each area. The subsoils observed in the profile pit at the lower area consisted of silty
gravelly sand. The subsoils on the upper bench were 2 to 3 feet of sand and gravel fill
over slightly silty sandy gravel with cobbles. The percolation tests indicate that in both
areas an average percolation rate of 50 to 60 minutes per inch should be used for
infiltration septic disposal design.
Limitations: The recommendations submitted in this letter are based on our
observation of the soils exposed within the pits excavated at the site. The risk of
foundation movement may be greater than indicated in this report because of possible
variations in the subsurface conditions. We should be informed of any changes in the
subsoil profile encountered during excavation.
If there are any questions or if we may be of further assistance, please let us know.
Sincerely,
HEPWORTH - PAWLAK GEOTECHNICAL, INC.
