The study was conducted in accordance with our agreement for geotechnical engineering services to you dated November 6, 1997. 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 consist of four connected single story wood frame structures located on the site as shown on Fig. I. A second story loft. will be built over the garage located on the western portion of the site. We understand the site is located within the flood plain of the Roaring Fork River. The residence is planned to be built on columns placed on footing pads to elevate the first floor of the structures about 4 feet above the existing ground surface. Floors will be structural. The garage at the west side of the residence will have continuous spread footing foundation and a slab-on-grade floor. Foundation loadings for this type of construction are assumed to be relatively light and typical of the proposed type of construction. The septic disposal system is proposed to be located between about 20 and. 30 feet to the northwest of the residence. If building conditions or foundation loadings are significantly different from those described above, we should be notified to re-evaluate the recommendations presented in this report, Site Conditions: The site is located on a working horse ranch. About 6 inches of snow covered the site at the time of our field work. The ground surface in the building area is relatively flat with a slight slope down to lhe north. There is about 4 feet of elevation difference across the site. A flowing irrigation ditch is located to the south of the building envelope. The lot is vegetated with cottonwood trees and an understory of grass and weeds. ,, , Richard Duddy November 25, 1997 Page 2 Subsurface Conditions: The subsurface conditions at the site were evaluated by excavating three exploratory pies in the building area and one profile pie in the septic disposal area at the approximate locations shown on Fig. I. The logs of the pits are presented on Fig. 2. 111e subsoils encountered, below about 'h to 2 feet of topsoil, consist of relatively dense sandy gravel with cobbles and scattered boulders. Results of a gradation analysis perfom1ed on a sample of the gravels (minus 5 inch fraction) obtained from the site arc presented on Fig. 3. Groundwater was observed in the pits at the time of excavation at a depth of abo@~to 3 feet and the soils were moist to wet. Foundation Recommendations: Considedng the subsoil conditions encountered in the exploratory pits and the nature of the proposed construction, we recommend footings placed on the undisturbed natural gravels designed for an allowable soil bearing pressure of 3,000 psf for support of the proposed residence. Due to the relatively shallow groundwater, excavation dewatering will be needed for construction of the footings. Footings should be a minimum width of 16 inches for continuous footings and 2 feet for column pads. 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 gravels. 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 in the garage should be reinforced top and bottom to span local anomalies such as by assuming an unsupported length of at least 10 feet. Garage Slab: The natural on-site gravels, exclusive of topsoil, are· suitable to support lightly 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 3 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 gravels devoid of vegetation, topsoil and oversized rock. Surface Drainage: The following drainage precautions should be observed during "'Onstruction and maintained at all times after the residence has been completed: 1) Exterior backfill should be adjusted to near optimum moisture and compacted to at least 95 % of the maximum standard Proctor density in H-P GEO"li:.C.H , i l ' I Richard Duddy November 25, 1997 Page 3 pavement and slab areas and to at least 903 of the maximum standard Proctor density in landscape areas. 2) 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. Percolation Testing: Percolation tests were conducted November 11, 1997 to evaluate the feasibility of an infiltration septic disposal system at the site. One profile pit and three percolation holes were dug at the locations shown on Fig. l. The test holes (nominal 12 inch diameter by 12 inch deep) were hand dug at the bottom of shallow backhoe pits and were soaked with water one day prior to testing. The soils exposed in the percolation holes are similar to those exposed in the Profile Pit shown on Fig. 2 and consist of about 'h foot of topsoil overlying sandy gravel with cobbles and scattered boulders. The percolation test results are presented in Table I. The percolation test results indicate an infiltration rate between 5 and 7 minutes per inch with an average of about 6 minutes per inch. The percolation rates were based on the last three readings of the test. Based on the shallow groundwater, a "mounded" system may be needed. The county may require thac the disposal system be designed by a civil engineer. Limitations: This study has been conducted in accordance with generally accepted geotechnical engineering principles and practices in this area at this time. We make no 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. I, the proposed type of construction and our experience in the area. Our findings include interpolation and extrapoJation 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 Che project evolves, we should provide continued consultation and field services during construction to review and monitor the implementation of our recommendations, and to verify thac 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 geotechnical engineer.
