Box 505 Edwards, Colorado 81632 Job No. 193 170 Subject: Subsoil Study for Foundation Design, Proposed Residence, Hardscrabble Mountain Road, 4 Miles South of Gypsum, Colorado. Dear Mr. Forsyth, As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study for design of foundations at the subject site. The study was conducted in accordance with our agreement for geotechnical engineering services to Roby Forsyth dated August 16, 1993. 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 single story above a walkout basement level. Ground floor will be slab -on -grade. 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 wilding conditions or foundation loadings are significantly different from those de;.cribed above, we should be notified to reevaluate the recommendations presented in this: report. Site: Conditions: The site consists of vacant property just south of an existing barn. The, ground surface in the area of the building site was mainly undisturbed and covered with grass, weeds, and some sagebrush. The building excavation was partly ditto a depth of about 5 1/2 feet at the uphill (east) corner. The ground surface slope is relatively gentle down to the west. Irrigated hay fields are located just south and east of, the building site. Subsurface Conditions: The subsurface conditions at the site were evaluated by observing two exploratory pits which had been dug prior to our site visit. The logs of tht pits are presented on Fig. 1. Pit 1 is located downhill in the proposed leach field ago and Pit 2 is located just uphill of the building site. The subsoils encountered in pits exposed in the excavation consist of about 2 to 4 feet of relatively loose govelly silt and sand above silty sandy gravel with cobbles. The coarse rock is nuinly subangular red sandstone fragments. Results of consolidation testing peformed on a relatively undisturbed sample of the silty sand, presented on Fig. 2, tdicate low compressibility under existing moisture conditions and light loading and a ligh collapse potential when wetted. Results of a gradation analysis performed on a Swnple;, of clayey gravel (minus 5-inch fraction) obtained from the site are presented M Fig. 3. No free water was observed in the pits and the soils were typically slightly nvistt . Roby Forsyth September 1, 1993 Page 2 Foundation Recommendations: Considering the subsoil conditions encountered in the exploratory pits and the nature of the proposed construction, spread footings placed on the undisturbed natural soil could be used for support of the residence with some risk of differential settlement. The soils are relatively loose and wetting could cause localized settlement and distress. Placing the footings below the upper sandy layer will reduce the settlement risk. Footings can be designed for an allowable soil bearing pressure of 1000 psf and should have a minimum width of 18 inches for continuous walls and 2 feet for columns. Loose and disturbed soils and the loose sand encountered at the foundation bearing level within the excavation should be removed and the footing bearing level deepened or the material should be moistened and compacted. 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 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 40 pcf for the on -site soil as backfill excluding oversized rock. Flo" Slabs: The natural on -site soils, exclusive of topsoil, are suitable to support lightly, loaded slab -on -grade construction. There is a risk of floor slab settlement due to vixtting of the upper sandy soils. 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,oint 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 canconsist of the on -site soils devoid of vegetation, topsoil and oversized rock. Unrdrain System: Although free water was not encountered during our ex#i;oration, it has been our experience in the area that local perched groundwater may dexelop during times of heavy precipitation or seasonal runoff. Frozen ground during sp�ng runoff can create a perched condition. We recommend below grade .crostruction, such as retaining walls, crawl space and basement areas, be protected fran wetting and hydrostatic pressure buildup by an underdrain system H74 G'EOTECH Roby Forsyth September 1, 1993 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 least 1 foot below the basement floor level and sloped at a minimum 1 % to a suitable gravity outlet. The walkout side of the basement should not need a foundation drain. 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 2 feet deep. An impervious liner such as 20 mil PVC should be placed below 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 slab and walkway 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 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. 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. 5) Landscaping which requires regular heavy irrigation should be located at least 10 feet from the building. Percolation Tests: Percolation tests were conducted in three hand dug holes between ;40 and 47 inches deep adjacent the west side of the existing barn and eWo a - �' o e rco a ion test resuis are presented Bn our m ings, a si a is suitable for an H-P GEOTECH Roby Forsyth September 1, 1993 Page 4 infiltration septic disposal system. A percolation rate of 20 minutes per inch can be used for the leach field area sizing. 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 indicated locations, 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. If you have any questions or if we may be of further assistance, please call our office. Sincerely, HEPWORTH - PAWLAK GEOTECHNICAL, INC. Steven L. Pawlak, Rev..
