The study was conducted in accordance with our agreement for geotechnical engineering services to you, dated April 19, 1993. The data obtained and our recommendations based on the proposed construction and subsurface conditions encountered are presented in this report. Chen - Northern, Inc. previously conducted a preliminary subsoil study for the Teller Springs Subdivision reported under Job No. 4 338 90. Proposed Construction: The proposed residence will be a one story block structure located on the site as shown on Fig. 1. A swimming pool is proposed southeast of the residence. Ground floor will be slab -on- grade. Cut depths of about 1 to 2 feet are assumed. 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 the vegetation consisted of grass, weeds, sagebrush, cactus and evergreens at the time of our visit. Man- placed fill was observed in two areas within the building site. The fill appears to be composed of sand and gravel and was probably placed during construction of an old railroad or roadway through the side. The site is generally flat in the proposed building area with steep slopes above to the west and below to the east. Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating two exploratory pits at the locations shown on Fig. 1. The logs of the pits are presented on Fig. 2. The subsoils encountered in Pit 1, below about 1 foot of topsoil, consist of silty sandy gravel. Backhoe refusal was encountered in Pit 1 at a depth of 4 feet. The subsoils encountered in Pit 2, below about 1 foot of topsoil, consist of about 3 1/2 feet of sandy silty clay overlying silty sandy gravel. Pit 2 was excavated to a depth of 8 feet. Results of a gradation analysis 4 member ol me ffi group d companies Mr. Rod Poland May 18, 1993 Page 2 performed on a sample of silty sandy gravel (minus 5 -inch fraction) obtained from Pit 1 are presented on Fig. 3. No free water was observed in the pits at the time of excavation. Test Pit 2 was also logged as a profile pit for leach field design. Foundation Recommendations: Considering the subsoils encountered in the exploratory pits and the nature of the proposed construction, we recommend spread footings placed on the undisturbed gravels designed for an allowable soil bearing pressure of 3000 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, sandy clay soils and existing fill encountered at the foundation bearing level within the excavation should be removed and the footings extended down to adequate natural bearing material. 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 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 45 pcf. Floor Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support lightly to moderately 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 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 mountainous areas 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 the proposed swimming pool, 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 CheneNorthern, Inc.Consulting Engineers and&lentos Mr. Rod Poland May 18, 1993 Page 3 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 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 bacldill 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 about 2 feet of the on -site, finer grained 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. 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 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 to be 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 exploratory information which has not been described or documented in this report. 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 of 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.
