The project site is shown on Figure 1. The purpose of the study was to develop recommendations for the foundation design. The study was conducted in accordance with our agreement for geotechnical engineering services to Woodsmith Construction dated February 5, 2009. An exploratory boring was drilled at the site to obtain information on the subsurface conditions. Samples of the subsoils obtained during the field exploration were tested in the laboratory to detennine their classification, compressibility or swell and other engineering characteristics. The results of the field exploration and laboratory testing were analyzed to develop recommendations for foundation types, depths and allowable pressures for the proposed addition foundation. This report summarizes the data obtained during this study and presents our conclusions, design recommendations and other geotechnical engineering considerations based on the proposed construction and the subsurface conditions encountered. PROPOSED CONSTRUCTION The proposed 28 foot by 18 foot addition will be a twci story, wood frame structure attached to the east side of the existing residence shown on Figure 1. The main floor level will be structural over a crawlspace. Grading for the structure is assumed to be relatively minor with cut depths between about 3 to 4 feet. We assume relatively light foundation loadings, typical of the proposed type of construction. lfbuilding loadings, location or grading plans change significantly from those described above, we should be notified to re-evaluate the recommendations contained in this report. Job No. 109 027 A -2- SITE CONDITIONS The property is located to the south of County Road 337 and was occupied by a two story, wood frame residence over crawlspace as shown on Figure 1. Lawn areas are located inunediately adjacent to the residence and a vacant pasture is located to the east. The ground surface around the existing residence and in the pasture was mostly covered with up to 4 inches of snow at the time of our field exploration. The ground surface in the area of the proposed addition was relatively flat with a gentle slope down to the northwest. There was about 1 foot of elevation difference across the approximate addition area. Vegetation consisted of grass (visible where the snow had melted) and several mature trees located around the residence. FIELD EXPLORATION The field exploration for the project was conducted on February 12, 2008. An exploratory boring was drilled at the location shown on Figure 1 to evaluate the subsurface conditions. The borings were advanced with 4-inch diameter continuous flight augers powered by a truck-mounted CME-45B drill rig. The boring was Jogged by a representative of Hepworth-Pawlak Geotechnical, Inc. Samples of the subsoils were taken with 1% inch and 2 inch I. D. spoon samplers. The samplers were driven into the subsoils at various depths with blows from a 140 pound hammer falling 30 inches. This test is similar to the standard penetration test described by ASTM Method D-1586. The penetration resistance values are an indication of the relative density or consistency of the subsoils. Depths at which the samples were taken and the penetration resistance values are shown on the Log of Exploratory Boring, Figure 2. The samples were retumed to our laboratory for review by the project engineer and testing. SUBSURFACE CONDITIONS A graphic log of the subsoil profile encountered in the boring is shown on Figure 2. The subsoils, below about Y, foot of topsoil, consist of about 4\1, feet of sandy clay and 3 feet of silty sand with scattered gravel overlying relatively dense basalt rocks up to possible boulder size in a sandy clay matrix down to the maximum explored depth of2! feet. Job No. 109 027A ~tech -3 - Laboratory testing performed on samples obtained from the borings included natural moisture content, density and percent finer than No. 200 sieve (silt and clay fraction) gradation analyses. Results of swell-consolidation testing performed on a relatively undisturbed drive sample, presented on Figure 4, indicate low to moderate compressibility under conditions ofloading and wetting. The laboratory testing is summarized in Table !. No free water was encountered in the boring at the time of drilling and the subsoils were slightly moist to moist. DESIGN RECOMMENDATIONS FOUNDATIONS Considering the subsurface conditions encountered in the exploratmy boring and the nature of the proposed construction, we recommend the addition be founded with spread footings bearing on the natural subsoils. The design and construction criteria presented below should be observed for a spread footing foundation system. I) Footings placed on the undisturbed natural subsoils should be designed for an allowable bearing pressure of I ,500 psf. Based on experience, we expect settlement of footings designed and constructed as discussed in this section will be about 1 inch or less. Settlements could be differential between the existing foundation and new footings. 2) The footings should have a minimum width of18 inches for continuous walls and 2 feet for isolated pads. 3) Exterior footings and footings beneath unheated areas should be provided with adequate soil cover above their bearing elevation for frost protection. Placement of foundations at least 36 inches below exterior grade is recommended for this part of Garfield County. Job No. 109 027 A ~tech -4- 4) 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 also be designed to resist a lateral earth pressure corresponding to an equivalent fluid unit weight of at least 55 pcf for the on-site soils as backfill, devoid of topsoil, vegetation and oversized rock. 5) Any existing fill, topsoil and any loose or disturbed soils should be removed and the footing bearing level extended down to undisturbed natural soils. The soils exposed in footing areas should be moistened and compacted prior to constructing footings. 6) A representative of the geotechnical engineer should observe all footing excavations prior to concrete placement to evaluate bearing conditions. UNDERDRAIN SYSTEM Although free water was not encountered during our exploration, it has been our experience that local perched groundwater can develop during times of heavy precipitation or seasonal runoff Frozen ground during spring runoff can create a perched condition. We reconnnend the craw !space area (if deeper than 4 feet) be protected from wetting and hydrostatic pressure buildup by an underdrain system. An underdrain system is not needed for a crawlspace area shallower than 4 feet provided that the wall backfill is well compacted and positive surface drainage away from the foundation is maintained around the addition. If provided, the drain should consist of drainpipe surrounded above the invert level with free-draining granular matetial. The drain should be placed at each level of excavation and at least I foot below lowest adjacent finish grade and sloped at a minimum I% to a suitable gravity outlet or sump and pump. 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 of2 inches. The drain gravel backfill should be at least I Y, feet deep. An impervious membrane, such as 20 or 30 mil PVC, should be placed beneath the drain gravel in a trough shape and attach to the foundation Job No. 109 027 A ~tech -5 - 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 addition has been completed: I) Inundation of the foundation excavations 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. 3) The ground surface surrounding the exterior of the addition should be sloped to drain away from the foundation in all directions. We recommend a minimum slope of 6 inches in the first I 0 feet in unpaved areas and a minimum slope of3 inches in the first I 0 feet in paved areas. Free-draining wall backfill should be capped with about 2 feet of the on- site, fine grained soils to reduce surface water infiltration. 4) Roof downspouts and drains should discharge well beyond the limits of all backfill. 5) Landscaping which requires regular heavy irrigation and sprinkler heads should be located at least 5 feet from foundation walls. 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 express or implied. The conclusions and recmrunendations submitted in this report are based upon the data obtained from the exploratory boring drilled at the location indicated on Figure I, the proposed type of construction and our experience in the area. Our services do not include determining the presence, prevention or possibility of mold or other biological contaminants (MOBC) developing in the future. If the client is concerned about MOBC, then a professional in this special field of practice should be No. 109 027A ~tech -6- consulted. Our findings include extrapolation of the subsurface conditions identified at the exploratory boring and variations in the subsurface conditions may not become evident until excavation is performed. If conditions encountered during construction appear different fi"om those described in this report, we should be notified so that 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 geotechnical engineer.
