SCOPE
This report presents the results of our soils and foundation investigation for the
proposed Kennedy Residence to be built on Lot 3 of the Lazy Diamond "A" Subdivision
in Garfield County, Colorado. We explored the subsurface conditions at the site to
provide foundation recommendations for the building. This report includes a description
of the subsurface conditions found in our test pits, a recommended foundation system
and geotechnical criteria for it and construction criteria for details influenced by the
subsoils. Our report was prepared from data developed during our field exploration,
laboratory testing, engineering analysis and our experience with similar conditions. A
summary of our conclusions is presented below.
SUMMARY OF CONCLUSIONS
1. Our test pits penetrated 1 foot of organic, sandy, silty clays above 3 to 4
feet of medium stiff sandy clays with some gravels and boulders above
dense, clayey gravels with cobbles and boulders in our test pits TP -1 and
TP -2 respectively. Free groundwater was not found in our test pits at the
time of drilling.
2. We recommend founding the residence with footings bearing on the native
gravels. A maximum soil bearing pressure is presented in the "Foundation"
section.
3. A ground surface slope away from the building should be maintained at
all times to reduce the risk of wetting soils below foundations.
SITE CONDITIONS
Lot 12 is adjacent to Home Place in the Lazy Diamond "A" Subdivision
approximately 3 miles south of the Glenwood Springs Airport in Garfield County,
Colorado. The area is an alluvial terrace formed by glaciation and the Roaring Fork River.
The ground surface is gently rolling and slopes from the southwest to the
northeast at grades visually estimated at 4 to 6 percent. Ground surfaces are covered
with pasture grasses, weeds and clusters of scrub oak. Several small irrigation ditches
which trend to the north and northeast cross the property.
PROPOSED CONSTRUCTION
A single family residence will be built. The building will be wood framed, two
stories tall with an attached garage. It had not been decided at this writing if a basement
will be built. Lower level living area floors will be slabs -on- grade. Foundation loads we
assumed for our analysis were between 1,000 and 3,000 pounds per lineal foot on
continuous footings and maximum interior column loads of 10 kips. We should be
informed if the actual construction is different than described above.
SUBSURFACE CONDITIONS
Two (2) test pits were excavated with a rubber tired backhoe at the locations
shown on Fig. 1 to investigate subsurface conditions for foundation recommendations.
Excavation was directed by our engineering geologist who logged the soils and obtained
samples. Summary logs of the soils found in our test pits, results of field penetration
resistance tests, and data from laboratory testing are shown on Fig. 2.
Our test pits penetrated 1 foot of organic, sandy, silty clays above 3 to 4 feet of
medium stiff sandy clays with some gravels and boulders above dense clayey sandy
gravels with cobbles and boulders in our test pits TP -1 and TP -2 respectively. Free
groundwater was not found in our test pits at the time of drilling.
2
SITE GRADING
A layer of organic sandy, silty clays was found. The actual depth of organic soils
covering the proposed building footprint cannot be determined until excavation begins
at the site. Organic soils should be removed from below any building construction at the
site.
Thin fill (less than 2 feet thick) may be required below floor slabs. Fill can consist
of the on -site clays free of organic soils or vegetation. Fill should be placed in loose lifts
no more than 8- inches thick, moisture treated to within 2 percent of optimum moisture
content and compacted to at least 95 percent of the standard Proctor (ASTM D 698)
maximum dry density.
FOUNDATION
In our opinion, the residence can be founded with footings bearing on the natural
gravels. The footings should be designed and constructed with the following criteria:
1. Footings should bear on the natural gravels and be designed for a
maximum soil bearing pressure of 5000 psf. Materials loosened during the
excavation or forming process should be removed from the footing areas
prior to placing concrete. Organic soils are not suitable for supporting
footings;
2. Foundation walls on continuous footings should be reinforced top and
bottom, to span loose soil pockets. We recommend reinforcing steel
equivalent to that required for a simple span of 10 feet. Reinforcement
should be designed by a qualified structural engineer;
3. Minimum footing sizes are desirable. We suggest a minimum width of 16
inches for continuous footings and a size of at least 2 feet by 2 feet for
isolated column pads. Larger sizes may be required based on the
structural loads;
4. The soils under exterior footings should be protected from freezing. The
depth normally assumed for frost protection in the Glenwood Springs area
is 36 inches.
3
FLOOR SLABS AND EXTERIOR CONCRETE
We understand the lower level floors, garage floors, patios and sidewalks will be
slabs -on- grade. The natural clays or gravels free of organics are suitable to support slab-
on-grade floors. We recommend the following design and construction details for slabs -
on- grade;
1. The natural clays or gravels will provide bearing for slabs -on -grade floors
and exterior concrete flatwork. Organic soils are not suitable for slab
support and should be removed from under slab concrete. If required, fill
should be placed in 8 inch maximum loose lifts at 2 percent below to 2
percent above optimum moisture content and compacted to at least 95
percent of standard Proctor maximum dry density (ASTM D 698).
2. Slabs should be separated from exterior walls and interior bearing
members. Vertical movement of the slabs should not be restricted;
3. Plumbing below the slabs should be pressure tested. Trench backfill
should be moisture treated and compacted;
4. Frequent control joints should be provided. The American Concrete
Institute (ACI) recommends maximum joint spacing of 15 to 20 feet to
control cracking.
The above precautions will not prevent movement of the slabs in the event the subsoils
below become wet. They tend to reduce potential damage if movement occurs.
PERCOLATION TESTS
Percolation tests were performed at test locations P -1 through P -6 shown on
Figure 1. Test holes approximately 6 inches in diameter and 12 inches deep were cased
with perforated pipe in the soils found at the bottom of 4 foot deep backhoe excavated
pits. We measured percolation rates between 5 and 40 minutes per inch, most rates were
between 5 and 15 minutes per inch. We recommend a design percolation rate of 30
minutes per inch.
4
SURFACE DRAINAGE
The performance of foundations and concrete flatwork is influenced by the
moisture conditions in the subsoils. Wetting of below foundation soils can be reduced
by planned and maintained surface drainage. Wetting or drying of the open foundation
excavation should be avoided. The ground surface surrounding the residence should be
sloped to provide rapid run -off of water away from the residence in all directions. We
recommend a slope of at least 12 inches in the first 10 feet. Backfill of the foundation
walls should be moisture treated and compacted. Roof downspouts and drains should
discharge well beyond the limits of all backfill. Splash blocks or downspout extensions
should be provided at all discharge locations.
LIMITATIONS
Our test pits were spaced to obtain a reasonably accurate picture of the
subsurface. Variations in the subsurface conditions not indicated by our test pits will
occur. We should observe the completed excavation to confirm the soils are as
anticipated from our test pits.
Our report was based on conditions disclosed by our test pits, results of
laboratory testing, engineering analysis, and our experience. Criteria presented reflects
the proposed building as we understand it. We should be advised if the final design
differs from our assumptions to permit us to re- evaluate our conclusions.
This investigation was conducted in a manner consistent with the level of care and
skill ordinarily exercised by members of our profession currently practicing under similar
conditions in the locality of this project. No other warranty, express or implied, is made.
