GS04923·120 .r 1 1 2 2 3 4 4 4 5 5 6 7 8 9 10 SCOPE This report presents the results of our soils and foundation investigation for the single·family residence proposed on Lot 58 of Cerise Ranch in Garfield County, Colorado. We conducted this investigation to evaluate subsurface conditions at the site and provide geotechnical engineering recommendations for the proposed construction. Our report was prepared from data developed during drilling of exploratory borings at the site, laboratory testing, engineering analysis and our experience with similar conditions. This report includes a description of the subsurface conditions found in our exploratory borings and presents geotechnical engineering recommendations for design and construction of the recommended foundation, floor systems, below-grade walls, subsurface drain system and details influenced by the subsoils. If actual building plans will differ significantly from the descriptions contained in the report, we should be informed so that we can check that our recommendations and design criteria are appropriate. A summary of our conclusions is presented below. SUMMARY OF CONCLUSIONS 1. Subsurface conditions encountered in our exploratory borings consisted of about 1 to 1.5 feet of sandy clay "topsoil" and about 1 to 3.5 feet of sandy clay underlain by silty gravel with cobbles and boulders to the total explored depth of 6 feet below existing ground surface. Practical auger refusal occurred at multiple depths in our borings. Free ground water was not encountered in our exploratory borings at the time of drilling. 2. Our subsurface information indicates that the natural gravel soil is present at or near proposed foundation elevations for the residence. We recommend constructing the residence on footing foundations that are supported by the undisturbed gravel soil or structural fill. Design and construction criteria for footings are presented in the report. 3. Shallow ground water is likely present in the building envelope of this lot at times when water is conveyed in irrigation ditches. Slabs-on- grade should be constructed above the surrounding ground surface. An exterior foundation drain should be constructed adjacent to below MS KATIE ERICKSON ERICKSON RESIDENCE PROJECT NO. GS04923·120 1 T grade walls. A drain network consisting of washed rock and PVC pipe should be constructed on the floor in crawl space areas, if constructed. 4. Clay soil should be removed from below interior slabs-on-grade in finished living areas to a depth of at least 2 feet. Removal of clay soils to a depth of at least 2 feet below unfinished or exterior slabs-on-grade would likely enhance performance. The clay should be replaced with structural fill. We judge potential for differential movement will be low for slabs-on-grade supported by structural fill at this site. Structural fill to attain grades below slabs should be placed and compacted as recommended in the report. Additional discussion Is in the report. 5. Surface drainage should be designed to provide for rapid removal of surface water away from the residence. SITE CONDITIONS The lot is within Cerise Ranch, located north of State Highway 82 In Garfield County, Colorado. Lot 58 is in the southwestern part of the development and south of Sun Flower Loop. Single-family residential lots are to the east, west and north. Highway 82 is to the south. The lot is about 2 acres. The Jot has a narrow frontage on Sun Flower Loop and widens to about 120 feet adjacent to Highway 82. The building envelope is about 300 feet from the access off of Sun Flower Loop {See Figure 1). Common area open space, Irrigation, and utility easements occupy the majority ofthe southern portion of the lot. In general, ground surface in the building envelope slopes gently down to the southwest at grades of less than 3 percent. About 1 foot of snow was present on the lot at the time of our investigation. PROPOSED CONSTRUCTION Building plans were being developed at this writing. We understand the residence will be a two-story, wood-frame building with an attached garage. A crawl space below the main level floor or slab-on-grade floor will be constructed in living areas . We expect that a slab-on-grade floor is preferred in the garage. Foundation loads are expected to vary between 1,000 and 3,000 pounds per linear foot of MS. KATIE ERICKSON ERICKSON RESIDENCE PROJECT NO. GS04923·120 2 T foundation wall with maximum interior column loads of 30 kips. If construction will differ significantly from the descriptions above, we should be informed so that we can adjust our recommendations and design criteria, if necessary. SUBSURFACE CONDITIONS We investigated subsurface conditions at the site by drilling two exploratory borings (TH-1 and TH-2) with a track-mounted rill rig at the approximate locations shown on Figure 1. Exploratory drilling operations were directed by our laboratory/field manager who logged conditions exposed in the borings and obtained samples of the soils. Graphic logs of the soils In the exploratory borings are shown on Figure 2. Subsurface conditions encountered in our exploratory borings consisted of about 1 to 1.5 feet of sandy clay "topsoil" and about 1 to 3.5 feet of sandy clay underlain by silty gravel with cobbles and boulders to the maximum explored depth of 6 feet. Practical auger refusal occurred at multiple depths in our borings. Our observations during drilling indicated the clay was stiff to very stiff and the gravel was dense to very dense. Free ground water was not found in our exploratory borings at the time of drilling. The borings were backfilled immediately after drilling operations were completed. Samples of the subsoils obtained from our borings were returned to our laboratory for testing. A sample of the clay was selected for one-dimensional, swell- consolidation testing. During the test procedure the sample was loaded with 1,000 psf and then flooded. The resulting volume change (i.e. swell-consolidation} was measured. The sample of clay exhibited 0.3 percent swell. Our borings and experience in the area indicates a significant portion of the subsoils consist of cobbles and boulders. Swell-consolidation test results are presented on Figure 3. MS. KATIE ERICKSON ERI CKSON RESIDENCE PROJECT NO. GS04923·120 3 9 SITE EARTHWORK Excavation Our subsurface information indicates that excavations will encounter the clay and gravel soils with cobbles and boulders. Excavation for the building foundation and utilities can be accomplished using conventional, heavy-duty excavation equipment. Excavation sides will need to be sloped or braced to meet local, state and federal safety regulations. The clay will classify as a Type B soil and the gravel will classify as a Type C soil based on OSHA standards governing excavations. Temporary slopes deeper than 4 feet should be no steeper than 1 to 1(horizontal to vertical) in Type B soils and 1.5 to 1 in Type C soils. Contractors should identify the soils encountered in the excavations and refer to OSHA standards to determine appropriate slopes. Free ground water was not found in our exploratory borings at the time of drilling. We do not anticipate that excavations made during the late fall or winter months for foundations or utilities will penetrate ground water. Excavations made during spring snowmelt or when irrigation ditches are flowing may encounter ground water seepage. Excavations can likely be dewatered by sloping to a temporary sump where water can be removed by pumping. Structural Fill Structural fill may be required to attain grades for slabs-on-grade or footings. Voids resulting from the removal of boulders should be filled with densely compacted, granular structural fill. A COOT Class 6 aggregate base course, or similar soil, should be used as structural fill. Alternatively, the on-site gravel soils, free of organic matter, debris and rocks larger than 3 inches in diameter can be used as structural fill. MS. KATIE ERICKSON ERICKSON RESIDENCE PROJECT NO GS04923·12D 4 9 Structural fill should be placed in loose lifts of 10 inches thick or less, moisture-conditioned to within 2 percent of optimum moisture content, and compacted to at least 100 percent of standard Proctor (ASTM D 698) maximum dry density. Moisture content and density of fill and structural fill should be checked by a representative of our firm during placement. Fill and Backfill Proper placement and compaction of fill and backfill adjacent to the building is important to reduce infiltration of surface water. Fill and backfill should consist of the on-site soils or similar soils free of organics, debris and rocks larger than 4 inches in diameter. The fill and backfill should be placed in loose lifts of 10 inches thick or less, moisture-treated to within 2 percent of optimum moisture content, and compacted to at least 95 percent of standard Proctor (ASTM D 698) maximum dry density. The upper one to two foot thickness of backfill soil placed on the exterior of foundation walls should be a clay soil to limit infiltration of surface water. FOUNDATION Our subsurface Information indicates that the natural gravel soil is present at or near proposed foundation elevations for the residence. We recommend constructing the residence on footing foundations supported by the undisturbed gravel soil or structural fill. The completed foundation excavation should be observed by a representative of our firm, prior to placing forms, to confirm that the exposed soil is suitable for support of the footings as designed. Clay soils should be removed to a depth of at least 2 feet below footings and replaced with structural fill. Alternatively, the stem wall could be extended so that the footing is constructed on the natural gravel. Recommendations for structural fill composition, placement, and compaction were outlined in the Structural Fill section. Our experience indicates that maximum settlement offootings designed and constructed as recommended may be MS . KATIE ERICKSON ERICKSON RESIDENCE PROJECT NO. GS04923·120 ............ ....._ •·"""'Q1 A- 5 T about 1 inch. Recommended design and construction criteria for footings are presented below. 1. Footing foundations should be supported by the undisturbed gravel soil or structural fill. Soils loosened during excavation or the forming process for the footings should be removed or the soils can be re- compacted prior to placing concrete. 2. Footings supported by the gravel or structural fill can be designed for a maximum allowable soil bearing pressure of 4,000 psf. 3. Continuous wall footings should have a minimum width of at least 16 inches. Foundations for isolated columns should have minimum dimensions of 24 inches by 24 inches. Larger sizes may be required, depending upon foundation loads. 4. Grade beams and foundation walls should be well reinforced, top and bottom, to span undisclosed loose or soft soil pockets. We recommend reinforcement sufficient to span an unsupported distance of at least 10 feet. Reinforcement should be designed by the structural engineer. 5. The soils beneath exterior footings should be protected from freezing. We recommend the bottom of footings be constructed at a depth of at least 36 inches below finished exterior grades for frost protection. The Garfield County building department should be consulted regarding required frost protection depth. SLABS-ON-GRADE We understand that a slab-on-grade interior finished floor is being considered. We expect a slab-on-grade floor is preferred by the client in the garage. Slabs-on- grade should be constructed above surrounding ground surface elevations due to the potential for shallow ground water on this site. Clay soil should be removed to a depth of at least 2 feet below interior slabs-on-grade in finished living areas. Removal of clay soils to a depth of at least 2 feet below unfinished or exterior slabs-on-grade would likely enhance performance. The clay should be replaced with structural fill. We judge potential for differential movement will be low for slabs-on-grade supported MS. KATIE ERICKSON ERICKSON RESIDENCE PROJECT NO. GS04923·120 6 T by structural fill at this site. Structural fill should be placed and compacted in accordance with the recommendations outlined in the Structural Fill section. We recommend the following precautions for slab-on-grade construction at this site. 1. Slabs should be separated from exterior walls and interior bearing members with slip joints which allow free vertical movement of the slabs. 2. Underslab plumbing should be pressure tested for leaks before the slabs are constructed. Plumbing and utilities which pass through slabs should be isolated from the slabs with sleeves and provided with flexible couplings to slab supported appliances. 3 . Exterior patio and porch slabs should be isolated from the residence. These slabs should be well-reinforced to function as independent units. 4. Frequent control joints should be provided, in accordance with American Concrete Institute (ACI) recommendations, to reduce problems associated with shrinkage and curling. BELOW-GRADE CONSTRUCTION Foundation walls which extend below-grade should be designed for lateral earth pressures where backfill is not present to about the same extent on both sides of the wall. Many factors affect the values of the design lateral earth pressure. These factors include, but are not limited to, the type, compaction, slope and drainage of the backfill, and the rigidity of the wall against rotation and deflection. For a very rigid wall where negligible or very little deflection will occur, an "at-rest" lateral earth pressure should be used in design. For walls which can deflect or rotate 0.5 to 1 percent of wall height (depending upon the backfill types), lower "active" lateral earth pressures are appropriate. Our experience indicates typical foundation walls in residences deflect or rotate slightly under normal design loads, and that this deflection results in satisfactory wall performance. Thus, the earth pressures on the walls will likely be between the "active" and "at-rest" conditions. MS. KATIE ERICKSON ERICKSON RESIDENCE PROJ ECT NO. GS04923·120 7 y If the on-site soils are used as backfill, we recommend design of below-grade walls using an equivalent fluid density of at least 45 pcf for this site. This equivalent density does not include allowances for sloping backfill, surcharges or hydrostatic pressures. The recommended equivalent density assumes deflection; some minor cracking of walls may occur. If very little wall deflection is desired, a higher equivalent fluid density may be appropriate for design. Backfill placed adjacent to foundation wall exteriors should be placed as recommended in the Fill and Backfill section. SUBSURFACE DRAINAGE Crawl space areas, if constructed, may be subject to damp or moist conditions due to the potential for shallow ground water resulting from irrigation ditches and snowmelt on this lot. Water from rain, snow melt, and surface irrigation frequently flows through relatively permeable backfill placed adjacent to a residence and collects on the surface of relatively undisturbed soils at the bottom ofthe excavation. This can cause wetting of foundation soils, hydrostatic pressure on below-grade walls, and moist conditions in below-grade areas after construction. To mitigate these concerns, we recommend provision of a foundation drain around the residence. The drain should consist of a 4-inch diameter, slotted schedule 40 PVC pipe encased in free draining gravel. The drain should lead to a positive gravity outfall or to a sump pit where water can be removed by pumping. The finished structural floor should be constructed at least 1 foot above the surrounding ground surface. We recommend that the crawl space floor be constructed no lower than 3 feet below existing grades. Crawl space areas must be provided with efficient drainage. We recommend constructing drains below the crawl space areas consisting of 2-inch diameter, slotted PVC pipe installed on 8 to 10 foot centers and embedded in at least 6 inches of washed gravel. The pipes should convey water to perimeter drain collector pipes. Water collected should be discharged to a positive gravity outlet or to a sump pit where water can be removed by pumping. Placement of a mud slab or vapor barrier MS . KATIE ERICKSON ERICKSON RESIDENCE PROJECT NO. GS04923·120 8 T glued to the foundation walls should be considered above the washed rock. A typical foundation drain detail is presented on Figure 4. Ventilation is importantto maintain acceptable humidity levels in crawl spaces. The mechanical systems designer should consider the humidity and temperature of air, and air flow volumes, during design of crawl space ventilation systems. We believe it is appropriate to install an active ventilation system that is controlled by a humidistat. SURFACE DRAINAGE Surface drainage is critical to the performance of foundations, floor slabs and concrete flatwork. We recommend the following precautions be observed during construction and maintained at all times after the residence is completed: 1. The ground surface surrounding the exterior of the residence should be sloped to drain away from the residence in all directions. We recommend providing a slope of at least 6 inches in the first 5 feet around the residence in landscaped areas. 2. Backfill around the exterior of foundation walls should be placed as described in the Fill and Backfill section. 3. The residence should be provided with roof gutters and downspouts. Roof downspouts and drains should discharge well beyond the limits of all backfill. Splash blocks and downspout extensions should be provided at all discharge points. 4. Landscaping should be carefully designed to minimize irrigation. Plants used near foundation walls should be limited to those with low moisture requirements; irrigated grass should not be located within 5 feet of the foundation. Sprinklers should not discharge within 5 feet of the foundation and should be directed away from the building. 5. Impervious plastic membranes should not be used to cover the ground surface immediately surrounding the residence. These membranes tend to trap moisture and prevent normal evaporation from occurring. Geotextile fabrics can be used to control weed growth and allow some evaporation to occur. MS. KATIE ERICKSON ERICKSON RESIDENCE PRO.IECT NO. GS04923·120 9 9 LIMITATIONS The exploratory borings provide a reasonably accurate picture of subsurface conditions. Variations in the subsurface conditions not indicated by the borings will occur. We should observe the completed foundation excavation to confirm the natural gravel soil is exposed and suitable for support of the footings as designed. This investigation was conducted in a manner consistent with that level of care and skill ordinarily exercised by geotechnical engineers currently practicing under similar conditions in the locality of this project. No warranty, express or implied, is made.
