BERNIE HAINES Clt/1 GS-2013 .• [ SCOPE This report presents the results of our soils and foundation Investigation for the planned Wampler /Haines Residence to be built on Lot 16, Springridge In Garfield County, Colorado. We explored the subsurface conditions to provide foundation recommendations for the proposed building. This report Includes a description of the subsurface conditions found In our exploratory borings, a recommended foundation system and geotechnlcal criteria for It and construction criteria for details Influenced by the subsoils. Our report was prepared from data developed during our field exploration, laboratory testing, engineering analyses, and our experience. A summary of our conclusions Is presented below. SUMMARY OF CONCLUSIONS 1. Our exploratory borings penetrated 0.5 feet of soft, organic clays above medium stiff to very stiff, sandy to silty clays with scattered gravels. Free groundwater was not found In our exploratory borings the day of drilling. 2. We recommend founding the building with footings bearing on the undisturbed natural, sandy to silty clays. 3. The basement floor slab can bear on the natural clays. 4. A ground surface slope away from the building should be maintained at all times to reduce wetting of soils below foundations. SITE CONDITIONS Lot 16, Springridge Subdivision Is located at the end of Springridge Drive approximately 3 miles south of the Glenwood Springs Airport in Garfield County, Colorado. The area Is an alluvial terrace formed by glaciation and the Roaring Fork River. An existing horse arena and parking area are above the planned building location to the north and east. Access Is from the cul- de-sac end of Springridge MR. BERNIE HAINES CTL/r OS-2076 1 [_J Drive to an access drive that Is to the north of the planned building footprint. Ground surfaces slope down to the west at grades visually estimated at 10 to 15 percent. Vegetation consists of Irrigated pasture grasses and weeds. Approximately 1.5 feet of snow covered the site during our field Investigation. PROPOSED CONSTRUCTION A single family residence will be built. The residence will be a two story wood frame building with a walk -out basement for a total of three levels. Floors In living areas will be structurally supported by the foundation system with a crawlspace below. The basement floor will be slab -on- grade. We understand that maximum excavations will be 10 feet deep. Foundation loads we assumed for our analysis were between 1,000 and 3,000 pounds per lineal foot along bearing walls and maximum Interior column Toads of 10 kips. We should be Informed if the actual construction or loads are different than described above to allow re- evaluation of criteria recommended herein. SUBSURFACE CONDITIONS Our senior field technician and engineering geologist directed the drilling of three (3) exploratory borings, one profile hole and three (3) percolation borings at the approximate locations shown on Figure 1 and obtained soil samples for testing In our laboratory. Summary Togs of our exploratory borings are shown on Figure 2. Results of laboratory testing are shown on Figures 3 and 4 and summarized on Table 1. Our exploratory borings penetrated 0.5 feet of soft, organic clays above medium stiff to very stiff, sandy to silty clays with scattered gravels. Free groundwater was not found in our exploratory borings the day of excavation. MR. BERNIE HAINES CTLIA OS -2076 2 .• Iv] SITE EXCAVATION We understand site excavation will consist of approximately 10 feet deep cuts for the basement. Excavation sides should be sloped. Excavated slopes will tend to collapse and flatten. We recommend temporary excavation slopes be 1 to 1 (horizontal to vertical) or flatter for the sandy to silty clays above groundwater. We believe the sandy to silty clays are Type B as described In the October, 1989 Occupation Safety and Health Administration (OSHA) Standards published by the Department of Labor governing excavations. The publication Indicates a maximum temporary slope of 1 to 1 (horizontal to vertical) for Type B soils above the water table. We should view the excavation to confirm that soils are as anticipated. Solis removed from the excavation should not be stockpiled at the edge of the excavation. We recommend the excavated soils be placed at a horizontal distance from the top of the excavation equal to at least the depth of the excavation. Free groundwater was not found In our exploratory borings. Depending upon cut depths and the time of year water may be present and enter the excavation. If free groundwater is encountered, we recommend excavations be sloped to a positive gravity outfall or to sumps where water can be removed by pumping. Excavations will tend to flatten to 2 to 1 (horizontal to vertical) or flatter below the water table. FOUNDATION The building can be founded with footings bearing on the natural, sandy to silty clays. Footings bearing on the natural clays may experience 1 -Inch total settlement and differential settlement of about 1/2 of the actual total settlement. Footings for the building can be designed and constructed with the following criteria: MR. BERNIE HAINES CTL/T 09-2075 3 • ve] 1. Footings bearing on the natural, medium stiff to very stiff, silty to sandy clays can be designed for a maximum allowable soil bearing pressure of 2,000 psf. Material loosened during the excavation or forming process should be removed from footing areas or compacted prior to placing concrete; 2. Foundation walls for continuous footings should be reinforced top and bottom to span undisclosed loose soil pockets. We recommend steel reinforcement equivalent to that required for a simple span of 10 feet. Reinforcement should be designed by a qualified structural engineer; 3. Minimum footing sizes are desirable. We recommend a minimum width of 16 inches for continuous footings and at least 2 feet by 2 feet for isolated column footings. Larger sizes may be required based on the structural loads; 4. The soils beneath exterior footings should be protected from freezing. We recommend footings be at least 36 Inches below finished exterior grades. The local building department should be contacted to verify required frost protection depth. FLOOR SLABS AND EXTERIOR CONCRETE We anticipate excavation at this site will expose sandy to silty clays. Basement and garage floors will be slabs -on- grade. We recommend the following design and construction criteria for slabs -on -grade floors: 1. Slabs -on -grade floors should bear on the natural, sandy to silty clays; 2. Slabs should be separated from exterior walls and interior bearing members with a joint to provide for free movement. Trench backflll should be moisture treated and compacted to at least 95 percent of standard Proctor maximum dry density (ASTM D 698); 3. Plumbing and utilities below slabs should be pressure tested prior to concrete placement and isolated from the slabs with sleeves; 4. Frequent control Joints should be provided. We suggest using the recommendations outlined by the American Concrete Institute (ACI). The above precautions will not prevent movement of slabs -on -grade floors in the event the soils become wet, but they will reduce the potential damage when movement occurs. MR. BERNIE MINES CTL/f 05-2075 4 BASEMENT CONSTRUCTION Basement walls will be up to 10 feet high and will be subjected to lateral earth pressure. These walls are restrained and cannot move, therefore, they should be designed for the "at rest" lateral earth pressure. Assuming on -site soils will be used as backflll, we recommend using an equivalent fluid density of 50 pcf to calculate the lateral earth pressure. The above lateral earth pressure value does not Include allowances for sloping backfill, loads from adjacent structures or hydrostatic loading that may develop. Backflll of the foundation walls should be moisture treated to within 2 percent of optimum moisture content and compacted to at least 90 percent of standard Proctor maximum dry density (ASTM D 698). Water from surface run -off (precipitation, snow melt, Irrigation) frequently flows through backflll placed adjacent to foundation walls and collects on the surface of the comparatively impermeable soils occurring at the bottom of the foundation excavation. This can cause wetting of soils below the foundation and damp or wet conditions In the basement. To reduce the accumulation of water, we recommend a foundation drain. The drain should consist of a 4-Inch diameter open joint or slotted PVC pipe encased in free draining gravel. The drain should lead to a positive gravity outfall or to a sump to be mechanically pumped. A typical foundation drain detail is shown on Figure 5. PERCOLATION TEST RESULTS Three (3) percolation tests were performed in the clays at locations shown as P -1 through P3 on Figure 1. The fast rates measured in our P -2 are likely due to localized anomalies In the subsoils such as sand lenses or close proximity of animal burrows. Percolation rates measured varied significantly in our percolation borings. Winter conditions may have effected results. We recommend additional percolation tests in the mid to late spring. Percolation test results are shown on Figures 6 through 8. MR. BERNIE HAINES CTUT 03.2076 5 SURFACE DRAINAGE Careful attention to surface drainage will be critical to the performance of foundations and concrete flatwork at this site. Performance of foundations and concrete flatwork Is influenced by moisture condltlons within the subgrade soils. Surface grading should cause rapid run -off of surface water away from the building in all directions. Sprinkler heads should be at least 10 feet from the building and be directed away from the building. We recommend landscaping that requires no or minimum Irrigation within 10 feet of the building. The following precautions should be observed during construction and maintained at all times after the construction is completed: 1. Wetting or drying of the open excavation should be avoided; 2. Water should not be allowed to pond adjacent to the building. The ground surface surrounding the building exterior should be sloped to cause rapid run -off of surface water away from the building. We recommend a finished ground surface slope of at least 12 Inches in the first 10 feet; 3. Plastic membranes should not be used to cover the ground surface Immediately surrounding the building. These membranes tend to trap moisture and prevent normal evaporation from occurring. Geotextlle fabric such as Mirafi or Typar can be used on the ground surface Immediately surrounding the building for weed growth control while allowing evaporation to occur; 4. Roof downspouts, drains and other water collection systems should discharge well beyond the limits of all backflll. Splash blocks or extensions should be provided at all discharge locations. LIMITATIONS Our exploratory borings were spaced to obtain a reasonably accurate picture of the subsurface conditions. Variations In the subsurface condltlons not Indicated by our exploratory borings will occur. We should observe the completed excavation to confirm the soils are as we anticipated from our exploratory borings. Placement and compaction of fill and backfill should be observed and tested during construction. MR. BERNIE HAINES CTIJT 05-2075 6 L Q I j Our report Is based on conditions disclosed by our exploratory borings, results of laboratory testing, engineering analysis and our experience. Criteria presented reflects the proposed building as we understand it. We should be advised If the final design differs from our assumptions to permit us to re- evaluate our conclusions and recommendations. 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 other warranty, express or Implied, is made. If we can be of further service or if you have questions regarding this report, please call. CTL/THOMPSON, IN Wilson L. "Llv" Bowden..

We performed percolation testing as part of our geotechnical investigation at the subject site (CTL/Thompson, Inc. Job No. GS -2075, dated February 25, 1997). Percolation test results at that time varied significantly and may have been effected by winter conditions. Test pits were excavated to a depth of approximately 3 feet deep with the contractors backhoe. A test hole 6 to 8 Inches In diameter was hand excavated an additional 12 to 18 Inches. The percolation test holes were saturated and percolation testing performed the following day. Test results are presented on the attached Figure 1. We recommend using a design percolation rate of 12 minutes per inch. We appreciate the opportunity to work with you on this project. If you have questions, please call.
