Box 666 �° (�✓ Basalt, Colorado 81621 Job No, 194 225 Subject: Subsoil Study for Foundation Design, Proposed Residence, Lot 13, Cook Subdivision, Adjacent to Aspen Mesa Estates, Vaquero Road, Cagle County, Colorado. Dear Mr. Steinmetz: As requested, Hepworth-Pawlak Geotechtlical, Inc. performed a subsoil study for design of foundations at the subject site. The study was conducted in accordance with out' agreement for geotechnical engineering services to you dated April 25, 1994. "The data obtained and our recotnlnendations based oil the proposed construction and subsurface conditions encountered are presented in this report. Proposed Construction: The proposed residence will be a one story wood frame structure over a partial crawl space and partial walkout basement located on the site as shown on Fig. 1. Basement and garage floors will be slab -on -grade. Cut depths are expected to range between about 3 to 7 feet. Foundation loadings for this type of construction are assured 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 at the time of our field work. The proposed building area is located at the transition between a moderately to steeply sloping forested hillside down to the south end a strongly sloping overgrown meadow (the topographic survey area shown on rig. 1). The vegetation in the building area consists of pinion and juniper trees, sage and rabbit brush, cactus and weeds. Many basalt cobbles and boulders were observed on the ground surface. Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating two exploratory pits at the approximate locations shown on Pig. 1. The logs Of the pits are presented on Pig. 2. "I'llc subsoils encountered, below about 1 1/2 feet of topsoil, consist of basalt cobbles and boulders in a silty sand and gravel matrix. Results of a gradation analysis performed on a sample of the silty san an gravel matrix (minus 3-inch fraction) obtained front the site are presented on Pig. 3. No free water was observed in the pits at the tillle of excavation and the soils were slightly lllolst to Illolst. Jim Steinmetz June 1, 1994 Page 2 Foundation Reconunendations: Considering the subsoil conditions encountered ill the exploratory pits and the nature of the proposed construction, we recommend spread footings placed on tine undisturbed natural soil designed for an allowable soil bearing pressure of 2,500 psf for support of the proposed residence. I ootings 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 and the footing bearing level extended down to the undisturbed natural soils. Holes created by boulder removal should be backfilled with lean concrete or compacted road base gravel. 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 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 45 pcf for tine on -site soil as backfill. 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. 'file requirements for joint spacing and slab reinforcement should be established by the designer based on experience and the intended slab use. /1 rrninitnum 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. Due to the large amount of oversized rock, it may be nnore practical to import road base material as fill under slabs. Underdraiu System: Although free water was not encountered during our exploration, it has been our experience in nnountainous areas that local perched groundwater nnay develop during tinnes of heavy precipitation or seasonal runoff. Frozen ground during Spring runoff can create a perched condition. We reconnnrend below grade H-P Grorrc:ii Jill) Steinmetz .tune 1, 1994 Page 3 construction, such as retaining walls, crawl space and basement areas, 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. Tire 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 about 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 minimull, 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. Percolation Test: Percolation testing was performed in ire e shallows )its' cavated south of the residence. The percolation test holes were soaked oil n it 27, 1994 and the percolation tests were perfoored on April 28, 1994. The percolation test results are shown on Table I. The percolation rate ranged from 30 to 40 minutes per inch, indicating the area is suitable for a conventional leach field septic systeni. 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 1-1-P G[OTFCII Jim Steinmetz June 1, 1994 Page 4 other warranty either expressed or implied. The conclusions and reconunendations 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 out - experience in the area. Our findings include interpolation and extrapolation of the subsurface conditions identified at the exploratory pits and variations it, the subsurface conditions may riot 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 set -vices during construction to review and monitor the implementation of our recommendations, and 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.
