Box 1356 Carbondale, Colorado 81623 Job No. 194 176 Subject: Subsoil Study for Foundation Design, Proposed Residence, Homestead #34, Panorama Ranch, Garfield County, Colorado. Dear Mr. Frizzell: As requested, Hepworth - Pawlak Geotechnical, Inc. performed a subsoil study for foundations design and percolation testing for leach field design at the subject site. The study was conducted in accordance with our agreement for geotechnical engineering services to you dated March 29, 1994. The building site is shown on Figs. 1 and 2. The data obtained and our recommendations based on the proposed construction and subsurface conditions encountered are presented in this report. Proposed Construction: The building plans were conceptual at the time of this study. The residence will generally be one and two stories possibly with a walkout lower level and located between the exploratory pits shown on Fig. 2. Ground floor will be above crawl space in the residence and slab -on -grade in the garage. 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 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 building site was vacant and covered with grass, weeds and sagebrush. Scrub oak stands are located below the building site in the leach field area. The terrain in the area is gently rolling with a strong slope down to the southwest. Elevation difference is about 6 feet in the building area. Occasional basalt cobbles are exposed on the ground surface. Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating two exploratory pits in the building area and two profile pits in the leach field area at the approximate locations shown on Fig. 2. The logs of the pits are presented on Figs. 3 and 4. The subsoils encountered, below about 3/4 to 1 1/2 feet of topsoil, generally consist of blocky sandy clay overlying basalt rock fragments in a calcareous sandy silt matrix at about 2 to 3 feet below ground surface. The rock content varied considerably from scattered in Pit 1 to mostly rock in the profile pits. Results of swell - consolidation testing performed on relatively undisturbed samples of the upper clay and sandy silt, presented on Fig. 5, indicate low compressibility under existing moisture conditions and light loading and low to moderate compressibility when wetted and loaded. No free water was observed in the pits at the time of excavation and the soils were slightly moist to moist. • Ray Frizzell April 19, 1994 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 2,000 psf for support of the proposed residence. Settlements are expected to be on the order of 1 inch. Footings should be a minimum width of 16 inches for continuous walls and 2 feet for columns. Loose and disturbed soils at the foundation bearing level within the excavation should be moistened and compacted or removed and the footing bearing level extended down to the undisturbed natural soils. Voids created by boulder removal should be backfilled with concrete or compacted base course. Exterior footings should be provided with adequate cover above their bearing elevations for frost protection. Placement of footings at least 36 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 12 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 (excluding oversize rock). Floor Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support lightly loaded slab -on -grade construction. The upper blocky clays may be expansive when wetted and result in some floor slab movement. 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, topsoil and oversized rock. Underdrain System: Although free water was not encountered during our exploration, it has been our experience in the area 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, crawl space and basement areas, be protected from wetting and hydrostatic pressure buildup by an underdrain system. H -P GEOTECH • • Ray Frizzell April 19, 1994 Page 3 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 2 inches. The drain gravel backfill should be at least 1 1/2 feet deep. 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 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 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. 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. Percolation Tests: Two profile pits were dug in the leach field area. Concentrated basalt rock could not be dug below 3 feet. The percolation tests were conducted in the upper clay soils. The test results, presented in Table II indicate rates between 20 and 80 minutes per inch. The test results indicate the leach field should be constructed in the underlying calcareous soils below the clays. The profile pits could not be dug with the relatively small backhoe. We recommend additional profile pits to verify adequate soil depth. 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 H -P GEOTECH . . • Ray Frizzell April 19, 1994 Page 4 submitted in this report are based upon the data obtained from the exploratory pits excavated at the locations indicated on Figs. 1 and 2, 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.
