As requested, KSM Engineering & Testing has performed a preliminary subsurface investigation
for the referenced project. The purpose of this investigation was to evaluate the near surface
soils with respect to the proposed project.
The site investigation program consisted of performing three (3) hand auger soil profiles, each to
a depth of 6 feet with static cone penetrometer readings. During the test, a shaft with a conical
point is pushed through the soil and the thrust required to push the cone tip is measured on an
attached calibrated gauge. The value of the bearing pressure exerted by the cone point allows
the operator to estimate the existing soil density. After the thrust was measured, the hole was
advanced with a hand -auger in 1-foot increments to permit a continuation of measurement of
relative density versus depth. The relationship of the static cone penetrometer reading to the
relative density is listed below:
Penetrometer Table
Relative Density
Static Penetrometer Reading

<15

Medium Dense

Based on the information obtained from this site investigation, we are pleased to offer the following
evaluation:
The boring logs indicate the subsurface soils consist mostly of fine-grained sand and fine-grained
clayed sand. No `muck' or other unsuitable soils were encountered in the test borings except for
the typical surface vegetation. Static cone penetrometer readings recorded during the
investigation indicates that the existing soil density is generally medium -dense. Please refer to
the soil boring logs for specific information relative to the soil description.

Based on the existing soil conditions, it is our professional opinion, that the soils to 6 feet below
grade are suitable for the proposed metal aircraft hanger provided that the site is properly
prepared.
Site Preparation:
The proposed building area and areas to be paved, plus a minimum margin of five feet beyond
proposed construction area shall be completely cleared of all surface debris, including vegetation,
roots and any organic matter. The building area should be graded level and proofrolled. Any soft,
yielding area should be excavated and replaced with clean compacted fill. Sufficient passes
should be made during compaction operations to produce a density no less than 95 percent of its
modified dry Proctor value to a depth of 2 feet.
After the exposed surface has been proofrolled, the building and pavement areas may be filled to
the desired grades. The fill material shall consist of clean granular sand containing less than 10%
material passing the U.S. Standard No. 200 mesh sieve. Place structural fill in loose layers of 12
inches in thickness and compact each lift to at least 95 percent of its modified dry Proctor value.
After excavating for the footings, the disturbed footing subgrade should be recompacted to 95
percent (minimum) of its modified dry Proctor value. This can be best achieved by making several
passes with a relatively light -weight walk -behind vibratory sled or roller.
Closure:
This report has been prepared in accordance with generally accepted soil and foundation
engineering practices based on the results of the test borings and the assumed loading conditions.
No warranties, either expressed or implied, are intended or made. This report does not reflect
any variations which may occur between the borings. If variations appear evident during the
course of construction, it would be necessary to re-evaluate the recommendations of this project.
Environmental conditions, wetland delineation, water quality, and municipal requirements are not
a part of this report.
We are pleased to be of assistance to you on this phase of your project. When we may be of
further service to you or should you have any questions, please feel free to contact the office.
