Subject: Subsoil Study for Foundation Design, Proposed Hofferbert Residence, Lot E-6, Aspen Equestrian Estates, Garfield County, Colorado

Dear Mr. and Mrs. Hofferbert:

As requested, Hepworth-Pawlak Geotechnical, Inc. performed a subsoil study for design

of foundations at the subject site. The study was conducted in accordance with our

agreement for geotechnical engineering services to you dated March 4, 2008. The data

obtained and our recommendations based on the proposed construction and subsurface

conditions encountered are presented in this report. Hepworth-Pawlak Geotechnical, Inc.

previously performed a preliminary geotechnical study for the proposed development

(Preshana Farms) and reported our fmdings August 31, 1998.

Proposed Construction: The proposed residence will be two story wood frame

construction above a crawlspace with an attached garage and located on the site as shown

on Figure I. Garage floor will be slab-on-grade. Cut depths are expected to range

between about 2 to 4 feet. Foundation loadings for this type of construction are assumed

to be relatively light and typical of the proposed type of construction.

If building conditions or foundation loadings are significantly different from those

described above, we should be notified to re-evaluate the recommendations presented in

this report.

Site Conditions: The site was vacant and snow cover was 6 inches at the time of our

exploration. Prior to development the area was irrigated pasture. Vegetation consists of

grass and weeds. The ground surface is relatively flat with a slight slope down to the

south. Blue Creek is located to the south of the site.

Parker 303-841-7119 ° Colorado Springs 719-633-5562 ° Silverthorne 970-468-1989

Subsidence Potential: Aspen Equestrian Estates is underlain by Pennsylvania Age Eagle

Valley Evaporite bedrock. The evaporite contains gypsum deposits. Dissolution of the

gypsum under certain conditions can cause sinkholes to develop and can produce areas of

localized subsidence. Evidence of sinkholes was not observed on the property during our·

preliminary study. Based on our present knowledge of the site, it cannot be said for

certain that sinkholes will not develop. In our opinion, the risk of ground subsidence at

Lot E-6 is low and similar to other lots in the area but the owner should be aware of the

potential for sinkhole development.

Subsurface Conditions: The subsurface conditions at the site were evaluated by

excavating three exploratory pits at the approximate locations shown on Figure 1. The

logs of the pits are presented on Figure 2. The subsoils encountered, below about one

foot of topsoil, consist of sandy silty clay overlying sandy gravel with cobbles and small

boulders. A boring drilled nearby (Boring 2) for our preliminary study indicated

relatively dense silty sandy gravel with cobbles and boulders below one foot of topsoil.

Results of swell-consolidation testing performed on a relatively undisturbed sample of the

sandy silty clay, presented on Figure 3, indicate low to moderate compressibility under

conditions ofloading and wetting. Results of a gradation analysis performed on a sample

of sandy gravel (minus 5 inch fraction) obtained from the site are presented on Figure 4.

No free water was observed in the pits at the time of excavation and the soils were

slightly moist to moist.

Foundation Recommendations: Considering the subsoil conditions encountered in the

exploratory pits and the nature of the proposed construction, we reconnnend spread

footings placed on the undisturbed natural granular soil designed for an allowable soil

bearing pressure of3,000 psffor support of the proposed residence. The garage

excavation will be shallow and the sandy silty clay should be removed from beneath

proposed footings. The grade can be reestablished with structural fill compacted to at

least 100% of the maximum standard Proctor density at a moisture content near optimum.

Footings should be a minimum width of 16 inches for continuous walls and 2 feet for

columns. Loose and disturbed soils encountered at the foundation bearing level within

the excavation should be removed and the footing bearing level extended down to the

undisturbed natural soils. Exterior footings should be provided with adequate 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. Continuous foundation

Job No.l 08 073A

walls should be reinforced top and bottom to span local anomalies such as by assuming

an unsupported length of at least I 0 feet. Foundation walls acting as retaining structures

should be designed to resist a lateral earth pressure based on an equivalent fluid unit

weight of at least 50 pcf for the on-site soil as backfill.

Floor Slabs: The natural on-site soils, exclusive of topsoil, are suitable to support lightly

loaded slab-on-grade construction. To reduce the effects of some differential movement,

floor slabs should be separated from all bearing walls and colunms with expansion joints

which allow unrestrained vertical movement. Floor slab control joints should be used to

reduce damage due to shrinkage cracking. The requirements for joint spacing and slab

reinforcement should be established by the designer based on experience and the intended

slab use. A minimum 4 inch layer of free-draining gravel should be placed beneath

basement level slabs to facilitate drainage. This material should consist of minus 2 inch

aggregate with less than 50% passing the No.4 sieve and less than 2% passing the No.

200 sieve.

All fill materials for support of floor slabs should be compacted to at least 95% of

maximum standard Proctor density at a moisture content near optimum. Required fill can

consist of the on-site soils devoid of vegetation, topsoil and oversized rock.

Underdrain System: Although free water was not encountered during our exploration, it

has been our experience in the area that local perched groundwater can develop during

times of heavy precipitation or seasonal runoff Frozen ground during spring runoff can

create a perched condition. Shallow groundwater is typical during the irrigation season.

We recommend below-grade construction, such as retaining walls and crawlspace areas,

be protected from wetting and hydrostatic pressure buildup by an underdrain system. A

shallow crawlspace (less than 3 feet) should not require an underdrain system provided

the exterior backfill is properly placed and compacted.

If drains are placed, they should consist of drainpipe placed in the bottom of the wall

backfill surrounded above the invert level with free-draining granular material. 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. 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.

Surface Drainage: The following drainage precautions should be observed during

construction and maintained at all times after the residence has been completed:

I) Inundation of the foundation excavations and underslab areas 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. Free-draining wall backfill should be

capped with about 2 feet of the on-site, finer graded soils to reduce surface

water infiltration.

3) The ground surface sun-ounding the exterior of the building 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 10 feet in pavement and

walkway areas.

4) Roof downspouts and drains should discharge well beyond the limits of all

backfill.

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

wan-anty either express or implied. The conclusions and recommendations submitted in

this report are based upon the data obtained from the exploratory pits excavated at the

locations indicated on Figure 1 and to the depths shown on Figure 2, 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 consulted. Our findings include interpolation and

extrapolation of the subsurface conditions identified at the exploratory pits and variations

in the subsurface conditions may not become evident until excavation is performed. If

conditions encountered during construction appear different from those described in this

report, we should be notified at once so 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.

If you have any questions or if we may be of further assistance, please let us know.
