FOUNDATIONS
1. Concrete foundations are designed based on the following soil parameters as reported in an Observation of Excavation prepared
by Kumar & Associates Inc. for the residence at 255 Maroon Drive, Glenwood Springs, Colorado, Project No. 19-7-705, dated
December 31, 2019.
Allowable bearing pressure = 3,000 psf
Lateral At -Rest Earth Pressure = 55 pcf
Lateral Active Earth Pressure = 45 pcf
Lateral Passive Earth Pressure = 350 pcf
Coefficient of Friction for Footing = 0.35
Frost Depth = 36" (per Garfield County)
2. Soils conditions and types, at the proposed foundation bearing elevations, shall be verified as adequate for the noted soil values,
by a representative of a qualified Geotechnical Engineer (emlployed by Oner) during excavation.
3. Proper surface and below grade perimeter drainage shall be intalled per Civil & Geotechnical Engineers to relive foundation from
hydrostatic pressures.
4. It is the responsibility of the Contractor to review the Geotechnical Engineer's recommendations and notify the Architect and/or
S.E.O.R. if any changes to the design are required prior to start of construction.
5. Overexcavate 3'-0" minimum below bottoms of footings and replace with compacted structural fill as specified in Geotechnical
report. Overexcavate 2'-0" minimum below slabs on grade in garage and lower level living areas and replace with compacted
structural fill.
