We understand that the proposed residence will consist of a wood frame building with cast in place concrete foundations and concrete slab on grade construction. The site is located in the Colorow Subdivision in the southwestern portion of Eagle County, Colorado. The site slopes toward the northeast at gradients estimated to ranged from 4 to 10 percent. Two soil test pits were performed to help determine the foundation design parameters. The site has a grass root mat of approximately 1 foot in thickness. The subsurface soils at the site consist of sandy silty CLAY, and silty SAND, and slightly sandy SILT which con ai ria le amoun s o grave and boulde The foundations at the site may be designed for a bearing pressure of 2000 psf for footings located in the sandy silty CLAY and silty SAND. SCOPE This report presents the results of a Geotechnical Investigation for the proposed residence to be constructed on Lot 12A, of Colorow Subdivision, Eagle County, Colorado. The investigation was performed digging soil test pits, obtaining soil samplesfor laboratory testing, and by presenting our findings in this report. The purpose of this foundation exploration was to evaluate the soil for foundation support, and the engineering characteristics of the foundation materials, and to provide criteria from a geotechnical point of view, for use by the owner in preparing the foundation design, and in preparing grading and drainage plans. 4 SITE LOCATION AND DESCRIPTION The site is an undeveloped lot located in the Colorow Subdivision. The site, Lot 12A, is bounded by partially wooded and wooded lots. The eastern boundary consists of Colorow Road. The site slopes toward the northeast at gradients estimated to ranged from 2 to 10 percent. The site is wooded with pine and aspen trees. and the ground surface contains a grass root mat. The ground surface was covered with snow at the time the test pits were excavated. SITE INVESTIGATION The subsurface exploration included a site reconnaissance by an Inter -Mountain Engineering Personnel and the excavation of two soil test pits observe the soil profile and obtain soil samples for laboratory testing. The test pits were excavated using a backhoe to the depths indicated in the Summary of Test Pits. :The test pit locations were established in the field by estimating right angles and pacing distances from site features. The approximate locations of the test pit location are illustrated on the Site Plan in the Appendix, refer to Drawing No. 1. The Appendix also contains Summary of Test Pits presenting the: information which was obtained in the subsurface exploration, a key to the terms used in the. Summary of Test Pits, and a brief description of the boring procedures used. 5 The ground surface elevations shown on the Summary of Test Pits were interpolated from the site plan and should be considered to be approximate. SUBSURFACE AND GROUNDWATER CONDITIONS The generalized soil stratigraphy is presented below. The .strata symbols and solid lines which are used to illustrate the various strata breaks on the Summary of Test Pits are approximate as the transitions between soil types may occur suddenly or relatively gradual. Underlying the topsoil at test pit No. 1, layer of reddish brown sandy silty CLAY which contained variable amounts of gravel and boulders was encountered to depths of approximately 5 feet. Underlying the reddish brown sandy SILT, slightly sandy SILT containing a little to some gravel and boulders was encountered. Underlying the topsoil at test pit No. 2, a layer of reddish brown clay, silty, SAND was encountered to a depth of approximately 3 feet. At a depth of 3 feet sandy, silty, CLAY was encountered to a depth of 6 feet. Results of the swell -consolidation indicate that the soils are non>to slightly expansive. The results of tests indicated to 0.6 percent swell under 1000 psf loading. �No measurable ground water was present at the time the soil test borings were completed. No long-term ground water observations were made. 6 PERCOLATION TESTING The percolation test were performed on December 22, 1995 in the vicinity of the proposed absorption field, refer to site plan. Three 6 inch diameter percolation. test holes were hand dug to depths of approximately 3 feet. The approximately locations of the percolation test holes is illustrated on Drawing No. 1. The test holes were filled with water 24 hours prior to testing to allow the soils to inundate. The water levels were measured to a relatively constant rate. The percolation rates are determined to average 77.7 minutes per inch. Although the percolation test holes and profile pits were dug to obtain a reasonable accurate determination of the absorption field conditions, variations in the subsurface conditions are also possible. Variations that exist beneath the absorption field may become evident during the excavation. A representative from our office should observe the completed excavation: to confirm that the soils encountered are as indicated by the soils profile hole. PROPOSED CONSTRUCTION The project site consists of the construction of a single family residence on the site. The residence is to be of wood frame construction with concrete slab on grade construction for the ground floor. We anticipate that the residence will be a two story 7 structure with a walk out basement. Foundation wall loading is anticipated to range from 1 to 5 kips per linear foot, and isolated column loading are anticipated to range from approximately 5 to 25 kips. FOUNDATION RECOMMENDATIONS Based upon the results of field explorations and the laboratory testing, we recommend that conventional spread footing foundation system be used. The foundations may be design for a bearing pressure of 2,000 psf for footings bearing on undisturbed reddish brown sandy silty CLAY and red silty SAND, and approved fill materials compacted to the recommendations provided herein. At this pressure, settlements are anticipated to be within tolerable limits for wood frame construction, provided the improvements in the bearing soils will be made as discussed herein. The footing excavations should be relatively smooth, free of debris, organics, loose soil, frost, and standing water. Any over - excavations should be backfilled and compacted to 100 percent within 2 percent of optimum moisture as determined by a Standard Proctor Test (ASTM D-698). A representative of this office should be contacted to inspect the foundation excavation to verify that the soil conditions are the same as those anticipated in this report. 8 After all of the final grading is completed, the bottom of the footings should be covered with a minimum of 48 inches of backfill for frost protection. Voids left by the removal of cobbles in the bottom of the footing excavation should be filled with lean concrete or a granular soils with a maximum particle size of 3 inches compacted to 100 percent of Standard Proctor Density (ASTM D7698), within 2 percent of optimum moisture. SLAB CONSTRUCTION The on -site soils, exclusive of Topsoil and Organics are suitable to support lightly loads slab -on -grade construction. However, because of the slightly expansive soils being present at the site, some movement of slab -on -grade floor systems may occur which may result in cracking.. To avoid unsightly cracking of slab - on -grade floor systems in living areas, we recommend that all ground level floors in living areas should consist of a structural floor over a crawl space. Cracking of concrete slab -on -grades in garages, unfinished basements areas, and patios must be controlled by providing a "free floating" slab by using a minimum 1" expansion joint between the slab and concrete foundation walls. The concrete slabs should have control joints on 10 to 15 foot intervals. Control joints are also recommended parallel to and approximately 8 inches from all basement walls. 9 All columns should be isolated from concrete slabs -on grade to prevent movement of the columns due to slab movement. The voids surrounding the columns should be expansion joint materials with a minimum 1" clearance. All excavations made for the foundations under proposed slab - on -grade areas must be properly backfilled with suitable material compacted to a minimum of 95 percent of the maximum Standard Proctor Density (ASTM D-698). Backfill place beneath slab -on -grade floor should be installed at -1 to +3% of optimum moisture content. The on -site soils, exclusive of topsoil and organics are suitable for use as backfill. Before the backfill is placed, all water and loose debris should be removed from these excavations. Prior to the construction of concrete floors, the undisturbed subgrade, free from topsoil and organics, should be proof rolled with a loaded rubber -tired loader or similar equipment to densify the near surface soils. To reduce the chance of damage to shallow utilities, special care should be taken in areas where underground utilities are present. The floor slabs should be appropriately reinforced, and joints should be provided at the junctions of the slab and the foundation walls, so that independent movement can occur without causing damage. The slabs should be scored at least 10 feet on center and in accordance with the American Concrete Institute's recommendations to help control cracking. Free vertical movement should be permitted around all utilities passing through the slab- 10 on -grade. Scores should also be made parallel to the foundation walls at a distance of approximately 8 inches from the walls. All partition wall (non -load bearing) located on slabs must have at a 1-1/2 inch void space at the base the walls to allow the slab to move vertically, refer to detail. The void spaced should be monitored periodically to ensure that the void does not close. A good alternative, to a concrete slab -on -grade floor with the associated risk of differential movements causing cracking, is to use structural floor systems with crawl spaces. Seasonal fluctuations and climatic conditions may cause some vertical movements in floor slabs. GROUNDWATER AND DRAIN SYSTEM While no ground water was reported in the soil test borings at the time the field investigation was conducted, it is possible that seasonal variations will cause fluctuations, or for a water table to be present in the upper soils during the spring months, or after prolonged periods of rain. A foundation perimeter drain as detailed on Figure No. 8 is recommended to reduce the risk of surface water infiltrating the footing subsoils. REINFORCING The foundation should be well reinforced and rigid enough to withstand differential settlements. Walls retaining earth should 11 be designed to resist an equivalent fluid pressure of 45 pcf for an "active" case assuming a level drained backfill condition. For "at rest" conditions such as basement walls, an equivalent fluid pressure value of 55 pcf may be used for "at rest" conditions. CRAWL SPACE COVER When moist soils are encountered in the excavation, the ground surface in crawl space areas should be covered with an impervious moisture barrier sealed against the footings. This will help to reduce humidity in the crawl space area. BACRFILL AND SURFACE DRAINAGE The foundation soils encountered in portions of the site must be prevented from being wetted after construction. The backfill placed around the foundation walls should be methodically compacted to help reduce settlement after completion of construction. The top one foot of the backfill material must be relatively impervious. The on -site soils, exclusive of Topsoil and Organics are suitable for use as backfill. Foundation wall backfill should be moistened or dried to near its optimum moisture content and compacted to at least 90,percent. of the maximum Standard Proctor Density. Structural backfill should be compacted to at least 95 percent of the maximum dry 12 density as determined by the Standard Proctor method of test (ASTM D 698). Surface water running toward the structure from upslope areas should be diverted around and away from the building by means of lined drainage swales or other similar measures. The final. grade should have a positive slope away from the foundation walls on all sides. A minimum of 12 inches in the first 10 feet is recommended. Downspouts and sill cocks should discharge into splash blocks that extend beyond the limits of the backfill. The use of long downspout extensions in place of splash blocks is advisable. LAWN IRRIGATION Do not install sprinkler systems next to foundation walls, porches or patio slabs. If sprinkler systems are installed, the sprinkler heads be aligned so that the spray from the heads, under full pressure, does not fall on foundation walls or within five feet of foundation walls', porches, or patio slabs. Lawn irrigation must be controlled and no flooding or ponding of water should be performed. If. the future owners desire to plant next to foundation walls, porches or patio slabs, and are willing to assume the risk of structural damage, etc., then it is advisable to plant only flowers and shrubbery (no lawn) of varieties that require very little moisture. These flowers and shrubs should be hand watered only. 1 MISCELLANEOUS The recommendations provided herein are based on experience in the area and from the on -site field exploration. The information obtained form the field exploration and laboratory testing reflects subsurface conditions only at the specific locations at the particular times designated. Subsurface conditions at other locations and times may differ from the conditions at these locations. The extent of any variations between the test pits may not appear evident until excavation is performed. However,. only minor variations are expected. If during construction conditions appear to be different, this office should be advised so re- evaluation of the recommendations may be made. This report has been prepared for the exclusive use of Steve Hill for the specific application to the proposed residence to be located on Lot 12A, Colorow Subdivision, Eagle County, Colorado. The findings and recommendations of this report have: been prepared in accordance with locally accepted professional engineering standards for similar conditions at this time. There is no other warranty, either expressed or implied. Sincerely, INTER UNT I�N%ENNGGI G, LTD. C/ Richard O. Ricks, P.E.
