Box 322 Carbondale, Colorado 81623 Job No. 197 668 Subject: Observation of Excavation, Proposed Residence, Lot 10, Cottonwood Hollow, Garfield County, Colorado Dear Mr. Milkovich: As requested, a representative of Hepworth - Pawlak Geotechnical, Inc. observed the excavation at the subject site on December 1 and 9, 1997 to evaluate the soils exposed for foundation support. The findings of our work and recommendations for the foundation design are presented in this report. The work was done in accordance with our agreement for geotechnical engineering services to JM Building Design, dated November 11, 1997. The proposed residence will be a single story structure of strawbale construction supported on a concrete grade beam over a rubble trench footing for frost protection. Perimeter drainage is proposed for the rubble trench foundation. Ground floor is proposed to be constructed of concrete pavers with radiant heat. The rubble trench footing was designed based on an assumed soil bearing pressure of 1,500 psf. The terrain in the building area slopes moderately down to the west. At the time of our initial visit to the site, the foundation excavation had been cut in one level from 0 to 9 feet below the adjacent ground surface. The soils exposed in the bottom of the excavation consisted of calcareous sandy silty clay with scattered gravel and cobbles in the eastern portion of the excavation and fill over topsoil in the western portion. We recommended subexcavating the fill and topsoil materials to expose the natural clays. When observed on December 9, 1997, the western portion of the excavation had been deepened 1 to 3 feet to expose the natural clays. Screened rock had been placed in voids created by remaining cobbles and small boulders. Results of swell - consolidation testing performed on a sample of clay taken from the site, shown on Fig. 1, indicate the soils have low compressibility under existing moisture conditions and light loading and a minor collapse potential (settlement under constant load) when wetted. The sample showed moderate compressibility under increased loading after wetting. No free water was encountered in the excavation and the soils were slightly moist to moist. Considering the conditions exposed in the excavation and the nature of the proposed construction; we recommend the rubble trench footings be placed on undisturbed natural soil designed for an allowable soil bearing pressure of 1,500 psf for support of the proposed residence. The exposed soils tend to compress when wetted and there could be some post - construction settlement of the foundation if the bearing soils become wet. The rubble trench materials should consist of free draining gravel with JM Building and Design December 9, 1997 Page 2 less than 2% passing the No. 200 sieve. Footings should be a minimum width of 18 inches for continuous walls and 2 feet for columns. Loose and disturbed soils in footing areas should be removed and the bearing level extended down to the undisturbed natural soils. Exterior footings should be provided with adequate soil 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. The concrete grade beam should be reinforced top and bottom to span local anomalies such as by assuming an unsupported length of at least 12 feet. Retaining structures should be designed to resist a lateral earth pressure based on an equivalent fluid unit weight of at least 50 pcf for on -site soil as backfill. The rubble trench drain should consist of perforated PVC pipe sloped to drain at about 1% grade to a suitable gravity outlet. Structural fill placed within floor areas can consist of the on -site soils compacted to at least 95 % of standard Proctor density at a moisture content near optimum. Backfill placed around the structure should be compacted and the surface graded to prevent ponding within at least 10 feet of the building. The recommendations submitted in this letter are based on our observation of the soils exposed within the foundation excavation and do not include subsurface exploration to evaluate the subsurface conditions within the loaded depth of foundation influence. This study is based on the assumption that soils beneath the footings have equal or better support than those exposed. The risk of foundation movement may be greater than indicated in this report because of possible variations in the subsurface conditions. In order to reveal the nature and extent of variations in the subsurface conditions below the excavation, drilling would be required. It is possible the data obtained by subsurface exploration could change the recommendations contained in this letter. If there are any questions or if we may be of further assistance, please let us know. Sincerely, HEP TH - PAWLAK GEOTEC INC. p p0 REG / � � �� , ti p • NAo 07 q,SF 1 ns.
