City of Springilsld Permit No. COM2004-o040 1
PURPOSE AND SCOPE
As requested, K & A Engineering, Inc. has completed a limited evaluatIon of salls at the subject SIte of the
constructIon eta sIngle-family residence on lot 12 of the St. LucIa Park subdivision The purpose of thIs
evaluation was to determine the suitability of the site for construction of the proposed conventionally framed
structure on cast-in-prace concrete spread foofings and to make recommendatIons for preparation 01 the
foundation pad.
FOUNDATION PREPARATION
The site is located on a flat lot south of Main Street off of a new extension of Aster Street There were no signs
of signIficant unstable areas (tensIon cracks, depressions, scarps) at the time of our inspection or during
excavation.
Solis at the site consisted of appiQJ(lmately 1.5-feet of loose brown OigaiiiC silts aliBi tan, moist, modeiataly
stiff, piastlc slits. The tan plastIc slits are moderately BxpanSlve. One spring was noted at the south east corner
of tile fOUndatIon excavation.
Preparation of the foundation pad was maae according to our on-site recommendations, ana conslstea of
stripping the surface organic slits, removing them off-site, and excavating to a depth of 2.5 to- 3.0-feet from the
existing ground surface to undisturbed slits Approximately 12 to 18-Inches 0' select granular fill consisting of
3"-lnch dense-graded Quarry rock was placed in 12.inch (maximum) lifts and compacted using a steel-wheeled
vibratory roller until no further deformation was evident dunng compaction at the edges 0' the roller
2 to 3-lnchs of Vol-Inch or 1 lh-Inch minus crushed aggregate was placed over the select granular 1111 and
compacted.
SUMMARY AND RECOMMENDATIONS
The foundation pad. as prepared, /s suItable to support the cast.in.p!ace concrete spread footings WIthout
significant heaving but with good,bearlno-capaclty (1,500 pounds per squara fcotallowabla bearing capacIty).
